5.Full Description of Material Change:

On October 30, 2023, the Company announced the terms of the Offer pursuant to which the Company will offer to purchase for cancellation up to C$1,500,000,000 of its Shares. Subject to obtaining certain exemptive relief under applicable securities laws in the United States, the Offer will proceed by way of a modified Dutch auction that includes the ability for shareholders to participate via a proportionate tender. The modified Dutch auction procedure will have a tender price range from C$78.50 per Share to C$94.00 per Share. Imperial has obtained routine exemptive relief from Canadian securities regulatory authorities with respect to the proportionate take-up and extension requirements of the Offer.

- 2 -

The Offer is expected to commence on November 3, 2023 and remain open for acceptance until 5:00 p.m. (Calgary time) on December 8, 2023, unless withdrawn, extended or varied by Imperial.

The Offer will be for up to approximately 3.4 percent of Imperial’s total number of issued and outstanding Shares (based on a purchase price equal to the minimum purchase price per Share and 554,945,083 Shares issued and outstanding as at the close of business on October 30, 2023).

Exxon Mobil Corporation (“ExxonMobil”), Imperial’s majority shareholder, advised Imperial that it will make a proportionate tender in connection with the Offer in order to maintain its proportionate Share ownership at approximately 69.6 percent following completion of the Offer.

Holders of Shares wishing to tender to the Offer may do so pursuant to: (i) auction tenders in which the tendering shareholders specify the number of Shares being tendered at a specified price of not less than C$78.50 per Share and not more than C$94.00 per Share in increments of C$0.25 per Share; (ii) purchase price tenders in which they will not specify a price per Share, but will rather agree to have a specified number of Shares purchased at the Purchase Price, as defined below; or (iii) proportionate tenders in which they will agree to sell, at the Purchase Price, a number of Shares that will result in them maintaining their proportionate Share ownership in Imperial following completion of the Offer. Shareholders who validly tender Shares without specifying the method in which they are tendering their Shares, or who make an invalid proportionate tender, including by tendering an insufficient number of Shares, will be deemed to have made a purchase price tender. For purposes of determining the Purchase Price, shareholders who make, or who are deemed to have made, a purchase price tender will be deemed to have tendered their Shares at the minimum price of C$78.50 per Share.

The purchase price to be paid by Imperial for each validly deposited Share taken up by the Company (the “Purchase Price”) will be determined upon expiry of the Offer and will be based on the number of Shares validly deposited pursuant to auction tenders and purchase price tenders, and prices specified by shareholders making auction tenders. As a result, Imperial’s shareholders who tender their Shares (other than ExxonMobil and shareholders who make proportionate tenders) will set the Purchase Price for the Offer. The Purchase Price will be the lowest price (which will not be less than C$78.50 per Share and not more than C$94.00 per Share) that enables the Company to purchase Shares up to the maximum amount available for auction tenders and purchase price tenders, determined in accordance with the terms of the Offer. Shares deposited at or below the Purchase Price as finally determined by Imperial will be purchased at such Purchase Price. Shares that will not be taken up in connection with the Offer, including Shares deposited pursuant to auction tenders at prices above the Purchase Price, will be returned to the shareholders.

If the aggregate purchase price for Shares validly tendered pursuant to auction tenders and purchase price tenders is greater than the amount available for auction tenders and purchase price tenders (after taking into consideration the proportionate

- 3 -

tenders), Imperial will purchase Shares from the shareholders who made purchase price tenders or tendered at or below the Purchase Price as finally determined by Imperial on a pro rata basis, except that “odd lot” holders (shareholders who own fewer than 100 Shares) will not be subject to proration.

Imperial expects to mail the formal offer to purchase, issuer bid circular, letter of transmittal, notice of guaranteed delivery and other related documents (collectively, the “Offer Documents”) containing the terms and conditions of the Offer, instructions for tendering Shares, and the factors considered by Imperial, the special committee of its board of directors (the “Special Committee”) and its board of directors (the “Board of Directors”) in determining to approve the Offer, among other considerations, on or about November 3, 2023. The Offer Documents will be filed with the applicable securities regulators in Canada and the United States and will be available free of charge on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov. Shareholders should carefully read the Offer Documents prior to making a decision with respect to the Offer.

The Offer will not be conditional upon any minimum number of Shares being tendered. The Offer will, however, be subject to other conditions described in the Offer Documents and Imperial will reserve the right, subject to applicable laws, to withdraw, extend or vary the Offer, if, at any time prior to the payment for deposited Shares, certain events occur.

The Board of Directors has approved the making of the Offer and the price range for the purchase of Shares thereunder upon the recommendation of the Special Committee. However, none of Imperial, the Special Committee, the Board of Directors, the dealer manager or the depositary makes any recommendation to any shareholder as to whether to deposit or refrain from depositing Shares under the Offer. Shareholders are urged to evaluate carefully all information in the Offer, consult their own financial, legal, investment and tax advisors and make their own decisions whether to deposit Shares under the Offer, how many Shares to deposit, whether to deposit Shares pursuant to the same tender option or different tender options and whether to specify a price or prices and, if so, at what price or prices to deposit such Shares.

This material change report does not constitute an offer to buy or the solicitation of an offer to sell Shares. An offer to buy the Shares will only be made pursuant to Offer Documents to be filed with the applicable securities regulators in Canada and the United States which remains subject to obtaining the necessary exemptive relief under applicable securities laws in the United States. The Offer will be optional for all shareholders, who will be free to choose whether to participate, how many Shares to tender and, in the case of auction tenders, at what price to tender within the specified range. Any shareholder who does not deposit any Shares (or whose Shares are not repurchased under the Offer) will realize a proportionate increase in equity interest in Imperial, to the extent that Shares are purchased under the Offer.

Imperial has retained RBC Capital Markets to act as financial advisor and dealer manager in connection with the Offer and Computershare Investor Services Inc.

- 4 -

(“Computershare”) to act as depositary. Any questions or requests for information may be directed to Computershare at 1 (800) 564-6253 (Toll Free within North America) or 1 (514) 982-7555 (outside North America) or to RBC Capital Markets as dealer manager for the Offer at ImperialSIB@rbccm.com.

The enforcement by U.S. Shareholders of civil liabilities under U.S. federal and state securities laws may be adversely affected by the fact that Imperial is incorporated under the Canada Business Corporations Act and located in Canada, and that certain of its directors and officers and the experts named in the Offer are non-residents of the United States.

OFFER TO PURCHASE FOR CASH

UP TO C$1,500,000,000 IN VALUE OF ITS COMMON SHARES AT A PURCHASE PRICE OF NOT LESS THAN

C$78.50 AND NOT MORE THAN C$94.00 PER COMMON SHARE

Imperial Oil Limited (“Imperial” or the “Company”) hereby offers to purchase for cancellation a number of common shares of the Company (the “Shares”) for an aggregate purchase price not exceeding $1,500,000,000. The purchase price of any Share taken up by the Company (the “Purchase Price”) will be determined in the manner described below but will not be less than $78.50 and not more than $94.00 per Share.

The offer by the Company is subject to the terms and conditions set forth in this offer to purchase (the “Offer to Purchase”), the accompanying issuer bid circular (the “Circular”), and the related letter of transmittal (the “Letter of Transmittal”) and notice of guaranteed delivery (the “Notice of Guaranteed Delivery”) (which together constitute, and are herein referred to as, the “Offer”).

The Offer commences on the date hereof and expires at 5:00 p.m. (Calgary time) on December 8, 2023, or at such later time and date to which the Offer may be extended by the Company (the “Expiration Date”), unless withdrawn. The Offer is not conditional upon any minimum number of Shares being properly deposited under the Offer. The Offer is, however, subject to other conditions and the Company reserves the right, subject to applicable laws, to withdraw, extend or vary the Offer if, at any time prior to the payment of any Shares, certain events occur. See Section 7 of the Offer to Purchase, “Certain Conditions of the Offer”.

Holders of Shares (the “Shareholders”) wishing to tender to the Offer may do so pursuant to:

•auction tenders in which the tendering Shareholders specify the number of Shares being tendered at a specified price (the “Auction Price”) of not less than $78.50 and not more than $94.00 per Share in increments of $0.25 per Share (the “Auction Tenders”);

•purchase price tenders in which the tendering Shareholders do not specify a price per Share, but rather agree to have a specified number of Shares purchased at the Purchase Price to be determined pursuant to the Offer (the “Purchase Price Tenders”), understanding that if they make a Purchase Price Tender such Shares will be deemed to have been tendered at the minimum price of $78.50; or

•proportionate tenders in which the tendering Shareholders agree to sell to the Company, at the Purchase Price to be determined pursuant to the Offer, a number of Shares that will result in them maintaining their respective proportionate Share ownership in the Company following completion of the Offer (the “Proportionate Tenders”).

Promptly following the Expiration Date, the Company will determine the Purchase Price, representing a single price per Share, which will not be less than $78.50 and not more than $94.00 per Share, taking into account the Auction Prices and the number of Shares deposited pursuant to Auction Tenders and Purchase Price Tenders. The Purchase Price will be the lowest price that enables the Company to purchase that number of Shares pursuant to valid Auction Tenders and Purchase Price Tenders having an aggregate purchase price not to exceed an amount (the “Auction Tender Limit Amount”) equal to (i) $1,500,000,000 less (ii) the product of (A) $1,500,000,000 and (B) a fraction, the numerator of which is the aggregate number of Shares owned by Shareholders making valid Proportionate Tenders, and the denominator of which is the aggregate number of Shares outstanding at the time of the Expiration Date. If the Purchase Price is determined to be $78.50 (which is the minimum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 19,108,280 Shares. If the Purchase Price is determined to be $94.00 (which is the maximum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 15,957,446 Shares. For the purpose of determining the Purchase Price, Shares tendered pursuant to a Purchase Price Tender will be considered to have been tendered at a price of $78.50 per Share (which is the minimum price per Share under the Offer). Shares tendered pursuant to a Proportionate Tender will be considered to have been tendered at a price per Share equal to the Purchase Price. Shares tendered by a Shareholder pursuant to an Auction Tender will not be purchased by the Company pursuant to the Offer if the price per Share specified by the Shareholder is greater than the Purchase Price. Shareholders who validly tender Shares without specifying the method in which they are tendering their shares, or who make an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender. Shareholders who wish to deposit Shares without specifying a price at which such Shares may be purchased by the Company should tender Shares in a Purchase Price Tender. Under a Purchase Price Tender, Shares will be purchased, upon the terms and subject to the conditions of the Offer, at the Purchase Price determined as provided herein.

Each Shareholder who has properly deposited Shares pursuant to an Auction Tender at or below the Purchase Price, a Purchase Price Tender or a Proportionate Tender and who has not withdrawn such shares will receive the Purchase Price, payable in cash (subject to applicable withholding taxes, if any), for all Shares purchased upon the terms and subject to the conditions of the Offer, including the provisions relating to proration and the preferential acceptance of odd lots described herein.

The Purchase Price will be payable in Canadian dollars; however, Shareholders may elect to receive the Purchase Price in United States dollars as described in the Offer. The risk of any fluctuation in exchange rates, including risks relating to the particular date and time at which funds are converted, will be borne solely by the Shareholder wishing to receive payment in United States dollars.

If the aggregate purchase price for Shares validly tendered and not withdrawn pursuant to Auction Tenders at Auction Prices at or below the Purchase Price and Purchase Price Tenders (collectively, the “Auction Tender Purchase Amount”) is less than or equal to the Auction Tender Limit Amount, the Company will purchase at the Purchase Price all Shares so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders.

If the Auction Tender Purchase Amount is greater than the Auction Tender Limit Amount, the Company will purchase a portion of the Shares so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders, as follows: (i) first, the Company will purchase all Shares tendered at or below the Purchase Price by Shareholders who own fewer than 100 Shares (the “Odd Lot Holders”) at the Purchase Price; and (ii) second, the Company will purchase at the Purchase Price on a pro rata basis that portion of the Shares tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders having an aggregate purchase price, based on the Purchase Price, equal to (A) the Auction Tender Limit Amount, less (B) the aggregate amount paid by

the Company for Shares tendered by Odd Lot Holders. Regardless of proration, the Company will always purchase at the Purchase Price, payable in cash (subject to applicable withholding taxes, if any), a number of Shares from Shareholders making valid Proportionate Tenders that results in such tendering Shareholders maintaining their respective proportionate Share ownership in the Company following completion of the Offer (subject to nominal differences due to the quantity of Shares purchased from such Shareholders being rounded down to the nearest whole number of Shares to avoid the purchase of fractional Shares). If the Auction Tender Purchase Amount is equal to or greater than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate purchase price equal to $1,500,000,000. If the Auction Tender Purchase Amount is less than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate purchase price equal to the product of (i) $1,500,000,000 and (ii) a fraction, the numerator of which is the Auction Tender Purchase Amount, and the denominator of which is the Auction Tender Limit Amount.

If no Auction Tenders or Purchase Price Tenders are made pursuant to the Offer, no Shares will be purchased by the Company (unless all Shareholders make valid Proportionate Tenders, in which case all Shares purchased will be purchased for $78.50 per Share).

All Auction Tenders, Purchase Price Tenders and Proportionate Tenders will be subject to adjustment to avoid the purchase of fractional Shares. All payments to Shareholders will be subject to deduction of applicable withholding taxes. See Section 3 of the Offer to Purchase, “Number of Shares, Proration and Proportionate Tenders”.

Certificates for all Shares not purchased under the Offer (including Shares not purchased because of proration and Shares deposited pursuant to Auction Tenders at prices in excess of the Purchase Price), or properly withdrawn before the Expiration Date, will be returned (in the case of certificates representing Shares all of which are not purchased) or replaced with new certificates representing the balance of Shares not purchased (in the case of certificates representing Shares of which less than all are purchased), promptly after the Expiration Date or termination of the Offer or the date of withdrawal of the Shares, without expense to the Shareholder. In the case of Shares tendered through book-entry transfer, such Shares will be credited to the appropriate account, without expense to the Shareholder.

Exxon Mobil Corporation (“ExxonMobil” or the “Principal Shareholder”) is the beneficial owner of 386,241,378 Shares, which represents approximately 69.6% of all issued and outstanding Shares. The Principal Shareholder has advised the Company that it will make a Proportionate Tender.

As of October 30, 2023, there were 554,945,083 Shares issued and outstanding. The Offer would be for approximately 3.4% of the total number of issued and outstanding Shares if the Purchase Price is determined to be

$78.50 (which is the minimum price per Share under the Offer) or approximately 2.9% of the total number of issued and outstanding Shares if the Purchase Price is determined to be $94.00 (which is the maximum price per Share under the Offer).

The Shares are listed and posted for trading on the Toronto Stock Exchange (the “TSX”) under the symbol “IMO” and have unlisted trading privileges on the NYSE American LLC (“NYSE American”) under the symbol “IMO”. On October 26, 2023, the last full trading day prior to the date of announcement of the Company’s intention to make the Offer, the closing price of the Shares on the TSX was $81.30 per Share and US$58.80 per Share on NYSE American. The lowest price that the Company may pay for Shares pursuant to the Offer is $78.50 per Share, which is below the closing price of the Shares on the TSX of $79.90 per Share on October 30, 2023. During the twelve months ended October 30, 2023, the closing prices of the Shares on the TSX have ranged from a low of $60.27 to a high of $84.34 per Share and on the NYSE American have ranged from a low of US$44.46 to a high of US$62.37 per Share.

In accordance with Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions, the Company has determined that: (i) a liquid market existed for the Shares at the time of the Offer, and (ii) it is reasonable to conclude that, following the completion of the Offer in accordance with its terms, there will be a market for holders of Shares who do not tender to the Offer that is not materially less liquid than the market that existed at the time of the making of the Offer. The board of directors of Imperial (the “Board of Directors”) has also obtained, on a voluntary basis, an opinion from RBC Capital Markets as of October 30, 2023 which, subject to the qualifications, assumptions and restrictions set out therein, confirms the determination of the Company with respect to market liquidity. A copy of the opinion is attached hereto as Schedule A.

The Board of Directors has approved the Offer. However, none of Imperial, the Special Committee (as defined below) or the Board of Directors, the Dealer Manager (as defined below) or the Depositary (as defined below) makes any recommendation to any Shareholder as to whether to deposit or refrain from

iii

depositing Shares under the Offer. Shareholders are urged to evaluate carefully all information in the Offer, consult their own financial, legal, investment and tax advisors and make their own decisions as to whether to deposit Shares under the Offer, how many Shares to deposit and whether to specify a price and, if so, at what price to deposit such Shares. No director or officer of the Company has advised the Company that he or she intends to deposit Shares under the Offer. See Section 3 “Purpose and Effect of the Offer”, Section 9 “Interest of Directors and Officers – Ownership of Imperial’s Securities” and Section 10 “Arrangements Concerning Shares – Acceptance of the Offer” of the Circular.

Shareholders should carefully consider the income tax consequences of having Shares being purchased under the Offer. See Section 13 of the Circular, “Income Tax Considerations”.

Shareholders wishing to deposit all or any portion of their Shares pursuant to the Offer must comply in all respects with the delivery procedures described herein. See Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”.

On November 4, 2022, the Company commenced a substantial issuer bid (the “Q4 2022 SIB”) pursuant to which it offered to purchase for cancellation up to $1.5 billion of its Shares through a modified Dutch auction and proportionate tender offer. The Q4 2022 SIB expired on December 9, 2022, with the Company repurchasing and cancelling a total of 20,689,655 Shares at a price of $72.50 per share, for a total consideration of $1.5 billion. On June 29, 2023, the Company commenced a normal course issuer bid to repurchase up to 29,207,635 Shares during the next 12 months (the “2023 NCIB”). On July 28, 2023, the Company announced plans to accelerate Share repurchases under the 2023 NCIB, and the purchase and cancellation of all Shares available under the 2023 NCIB were completed by October 19, 2023. A total of 29,207,635 Shares were repurchased and cancelled pursuant to the 2023 NCIB for a total consideration of approximately $2,300 million. See Sections 3 and 6 of the Circular, “Purpose and Effect of the Offer” and “Previous Purchases of Shares”.

Forward-looking statements are not guarantees of future performance and, by their very nature, involve a number of inherent risks and uncertainties, some that are similar to other oil and gas companies and some that are unique to the Company. Forward-looking statements are based on the Company’s current expectations, estimates, projections and assumptions, both general and specific, made by the Company in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors that the Company believes are appropriate and reasonable in the circumstances. The Company cautions that there can be no assurance that such assumptions will prove to be correct or that the Company’s expectations regarding this Offer or the Company’s business guidance, objectives, plans and strategic priorities will be achieved.

Many factors could cause the Company’s expectations regarding this Offer or the Company’s actual future financial and operating results, including expectations and assumptions concerning future energy demand, supply and mix; commodity prices and foreign exchange rates; production rates, growth and mix across various assets; production life, resource recoveries and reservoir performance; project plans, timing, costs, technical evaluations and capacities, and the company’s ability to effectively execute on these plans and operate its assets, including its investment in the renewable diesel complex at Strathcona and the Leming, Grand Rapids and LASER projects at Cold Lake; the adoption and impact of new facilities or technologies on reductions to GHG emissions intensity, including technologies using solvents to replace energy intensive steam at Cold Lake, boiler flue gas technology at Kearl, Strathcona renewable diesel, carbon capture and storage including in connection with hydrogen for the renewable diesel project, recovery technologies and efficiency projects and any changes in the scope, terms, or costs of such projects; that any required support from policymakers and other stakeholders for various new technologies such as carbon capture and storage will be provided; the amount and timing of emissions reductions, including the impact of lower carbon fuels; performance of third party service providers; receipt of regulatory and third party approvals in a timely manner; applicable laws and government policies, including with respect to climate change, GHG emissions reductions and low carbon fuels; refinery utilization and product sales; the ability to offset any ongoing inflationary pressures; cash generation, financing sources and capital structure, such as dividends and shareholder returns, including the timing and amounts of share repurchases; progression of COVID-19 and its impacts on Imperial’s ability to operate its assets; capital and environmental expenditures; the capture of efficiencies within and between business lines and the ability to maintain near-term cost reductions as ongoing efficiencies; and general market conditions to differ materially from those expressed or implied by the forward-looking statements.

These factors include, without limitation: global, regional or local changes in supply and demand for oil, natural gas, petroleum and petrochemical products, feedstocks and other market factors, economic conditions or seasonal fluctuations and resulting demand, price, differential and margin impacts; transportation for accessing markets; political or regulatory events, including changes in law or government policy, including foreign government action with respect to supply levels and prices, applicable royalty rates, tax laws including taxes on share buybacks, and actions in response to COVID-19; the occurrence of wars; environmental risks inherent in oil and gas activities; environmental regulation, including climate change and greenhouse gas regulation and changes to such regulation; government policies supporting lower carbon investment opportunities; failure or delay of supportive policy and market development for emerging lower emission energy technologies; the receipt, in a timely manner, of regulatory and third-party approvals; third-party opposition to company and service provider operations, projects and infrastructure; availability and allocation of capital; availability and performance of third-party service providers, unanticipated technical or operational difficulties; management effectiveness and disaster response preparedness; commercial negotiations; project management and schedules and timely completion of projects; unexpected technological developments; the results of research programs and new technologies, including with respect to greenhouse gas emissions, and the ability to bring new technologies to commercial scale on a cost-competitive basis; reservoir analysis and performance; the ability to develop or acquire additional reserves; operational hazards and risks; cybersecurity incidents, including increased reliance on remote working arrangements; currency exchange rates; the impacts of COVID-19 or other public health crises, including the effects of government responses on people and economies; general economic conditions, including the occurrence and duration of economic recessions or

downturns; and other factors discussed in Item 1A Risk Factors and Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Company’s Annual Report on Form 10-K dated February 22, 2023 and the Company’s quarterly reports on Form 10-Q for each of the three month periods ended March 31, 2023, June 30, 2023 and September 30, 2023, each of which is incorporated by reference in this cautionary statement.

These factors are not intended to represent a complete list of the factors that could affect the Company; however, these factors should be considered carefully. Other factors could also cause the Company’s expectations regarding the Offer to differ materially from those expressed or implied by the forward-looking statements.

The purpose of the forward-looking statements is to provide the reader with a description of management’s expectations and may not be appropriate for other purposes; readers should not place undue reliance on forward- looking statements made herein. Furthermore, unless otherwise stated, the forward-looking statements contained in this Offer are made as of the date of this Offer or the date of the documents incorporated herein, as applicable, and the Company has no intention and undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

The forward-looking statements contained in this Offer are expressly qualified by this cautionary statement.

INFORMATION FOR UNITED STATES SHAREHOLDERS

The Offer is made by Imperial, a Canadian issuer, for its own Shares, and while the Offer is subject to the disclosure requirements of the Province of Alberta and the other provinces and territories of Canada, U.S. Shareholders should be aware that these disclosure requirements are different from those of the United States.

The enforcement by Shareholders of civil liabilities under U.S. federal and state securities laws may be adversely affected by the fact that Imperial is incorporated under the Canada Business Corporations Act and located in Canada and that certain of its directors and officers and the experts named in the Offer are non-residents of the United States and that all or a substantial portion of the assets of the Company and said Persons are located outside the United States. It may be difficult to effect service of process on the Company, its officers and directors and the experts named in the Offer. In addition, U.S. Shareholders should not assume that courts in Canada or in the countries where such directors and officers reside or in which Imperial’s assets or the assets of such Persons are located (i) would enforce judgments of U.S. courts obtained in actions against Imperial or such Persons predicated upon civil liability provisions of U.S. federal and state securities laws as may be applicable, or (ii) would enforce, in original actions, any asserted liabilities against Imperial, its subsidiaries or such Persons predicated upon such laws. Enforcement of any asserted civil liabilities under U.S. securities laws may be further adversely affected by the fact that some or all of the experts named in the Offer may be residents of Canada.

U.S. Shareholders should be aware that the acceptance of the Offer will have certain tax consequences under United States and Canadian law. See Section 13 of the Circular, “Income Tax Considerations”.

CURRENCY

All dollar references in the Offer to Purchase and the Circular are expressed in Canadian dollars, except where otherwise indicated. References to “$” are to Canadian dollars and references to “US$” are to U.S. dollars.

On October 30, 2023, the Bank of Canada daily average exchange rate was $1.00 = US$0.72.

SUMMARY
This summary is provided for your convenience. It highlights certain material information relating to the Offer, but you should understand that it does not describe all of the details of the Offer to the same extent as described elsewhere herein. The Company therefore urges you to read the entire Offer to Purchase, Circular, Letter of Transmittal and Notice of Guaranteed Delivery because they each contain important information. References have been included to certain sections of the Offer where you will find a more complete discussion.
Purpose of the Offer			The Board of Directors believes that the purchase of Shares by the Company is in the best interests of the Company and its Shareholders. The Offer will allow the Company to return up to an additional $1,500,000,000 of capital to Shareholders who elect to tender their shares while at the same time increasing the Share ownership of Shareholders who elect not to tender. See Section 3 of the Circular, “Purpose and Effect of the Offer”.
Expiration Date			The Offer expires at 5:00 p.m. (Calgary time) on December 8, 2023 or at such later time and date to which the Offer may be extended by the Company, unless withdrawn. See Section 1 of the Offer to Purchase, “The Offer”.
Payment Date			The Company will comply with both Canadian and U.S. regulations governing the timing for acceptance of and payment for Shares. Under Canadian regulations, Imperial must take up the Shares to be purchased pursuant to the Offer as soon as reasonably practicable after the Expiration Date and in any event not later than 10 days after the Expiration Date, provided that the conditions of the Offer (as the same may be varied) have been satisfied or waived. Any Shares taken up will be paid for as soon as reasonably practicable, but in any event no later than three (3) Business Days after they are taken up in accordance with applicable Canadian securities laws. See Section 9 of the Offer to Purchase, “Taking Up and Payment for Deposited Shares”. Under U.S. regulations, Imperial is required to promptly accept for payment and promptly thereafter pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Date pursuant to the Offer. The Company currently expects to accept and pay for Shares validly tendered and not validly withdrawn prior to the Expiration Date on December 13, 2023, the 3rd Business Day following the Expiration Date (assuming the Expiration Date is not extended beyond December 8, 2023).
Currency of Payment			The Purchase Price will be denominated in Canadian dollars and payments of amounts owing to Shareholders whose Shares are taken up will be made in Canadian dollars. However, Shareholders may elect to receive the Purchase Price in United States dollars as described in the Offer. In such case, the risk of any fluctuation in exchange rates, including risks relating to the particular date and time at which funds are converted, will be borne solely by the Shareholder. See Section 2 of the Offer to Purchase, “Purchase Price”.
Methods of Tender			Shareholders wishing to tender to the Offer may do so pursuant to: •Auction Tenders in which the tendering Shareholders specify the number of Shares being tendered and specify an Auction Price of not less than $78.50 and not more than $94.00 per Share in increments of $0.25 per Share; •Purchase Price Tenders in which the tendering Shareholders do


			not specify a price per Share, but rather agree to have a specified number of Shares purchased at the Purchase Price to be determined pursuant to the Offer; or •Proportionate Tenders in which the tendering Shareholders agree to sell to the Company, at the Purchase Price to be determined pursuant to the Offer, a number of Shares that will result in them maintaining their respective proportionate Share ownership in the Company following completion of the Offer.
Purchase Price			The Purchase Price will be determined in the manner described in the Offer but will be not less than $78.50 and not more than $94.00 per Share, taking into account the Auction Prices and the number of Shares deposited pursuant to Auction Tenders and Purchase Price Tenders. The Purchase Price will be the lowest price that enables the Company to purchase that number of Shares pursuant to valid Auction Tenders and Purchase Price Tenders having an aggregate purchase price not exceeding the Auction Tender Limit Amount. All Shares purchased by the Company pursuant to the Offer (including Shares tendered at Auction Prices below the Purchase Price) will be purchased at the same Purchase Price. A Shareholder making an Auction Tender may deposit different Shares at different prices, but a Shareholder cannot deposit the same Shares pursuant to more than one method of tender or pursuant to an Auction Tender at more than one price. Shareholders may deposit different Shares pursuant to Auction Tenders and Purchase Price Tenders but cannot make an Auction Tender or Purchase Price Tender as well as a Proportionate Tender. The Company will return all Shares not purchased under the Offer, including Shares not purchased as a result of proration or invalid tender or Shares deposited pursuant to Auction Tenders at prices in excess of the Purchase Price, promptly after the Expiration Date. See Section 2 of the Offer to Purchase, “Purchase Price”.
Number of Shares to be Purchased			Imperial will purchase Shares under the Offer to a maximum aggregate amount of $1,500,000,000. Since the Purchase Price will only be determined after the Expiration Date, the number of Shares that will be purchased will not be known until after the Expiration Date. If the Auction Tender Purchase Amount is equal to or greater than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate value equal to $1,500,000,000. If the Auction Tender Purchase Amount is less than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate purchase price equal to the product of (i) $1,500,000,000, and (ii) a fraction, the numerator of which is the Auction Tender Purchase Amount, and the denominator of which is the Auction Tender Limit Amount. See Section 3 of the Offer to Purchase, “Number of Shares, Proration and Proportionate Tenders”.
Proration			If the aggregate purchase price for Shares validly tendered and not withdrawn pursuant to Auction Tenders at Auction Prices at or below the Purchase Price and Purchase Price Tenders is less than or equal to the Auction Tender Limit Amount, the Company will purchase at the Purchase Price all Shares so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders. If the Auction Tender Purchase Amount is greater than the Auction Tender Limit Amount, the Company will purchase a portion of the Shares


			so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders, as follows: (i) first, the Company will purchase at the Purchase Price all Shares tendered by Odd Lot Holders at or below the Purchase Price; and (ii) second, the Company will purchase at the Purchase Price on a pro rata basis that portion of the Shares tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders having an aggregate purchase price, based on the Purchase Price, equal to (A) the Auction Tender Limit Amount, less (B) the aggregate amount paid by the Company for Shares tendered by Odd Lot Holders. The Company will purchase at the Purchase Price, payable in cash (subject to applicable withholding taxes, if any), a number of Shares from Shareholders making valid Proportionate Tenders that results in such tendering Shareholders maintaining their respective proportionate Share ownership in the Company following completion of the Offer (subject to nominal differences due to the quantity of Shares purchased from such Shareholders being rounded down to the nearest whole number of Shares to avoid the purchase of fractional Shares). See Section 3 of the Offer to Purchase, “Number of Shares, Proration and Proportionate Tenders”.
Delivery Procedure			Each Shareholder wishing to deposit Shares pursuant to the Offer must: •provide certificates or DRIP position for all Deposited Shares in proper form for transfer, together with a properly completed and duly executed Letter of Transmittal, in accordance with the instructions in such Letter of Transmittal, together with all other documents required by the Letter of Transmittal and must be delivered to, and received by, the Depositary at one of the addresses listed in the Letter of Transmittal by the Expiration Date; •follow the guaranteed delivery procedure described in Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”; or •transfer Shares pursuant to a book-entry transfer, provided that a Book-Entry Confirmation through the CDSX system (in the case of Shares held in CDS) or an Agent’s Message (in the case of Shares held in DTC) is received by the Depositary at its office in Toronto, Ontario prior to the Expiration Date (as such terms are defined herein). A Shareholder who wishes to deposit Shares under the Offer and who holds such Shares through an investment dealer, stock broker, bank, trust company or other nominee should immediately contact such nominee in order to take the necessary steps to be able to deposit such Shares under the Offer. See Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”.
Brokerage Commissions			Shareholders depositing Shares will not be obligated to pay brokerage fees or commissions to the Company or to the Depositary. However, Shareholders are cautioned to consult with their own brokers or other intermediaries to determine whether any fees or commissions are payable to their own brokers or other intermediaries in connection with a deposit of Shares pursuant to the Offer. See Section 9 of the Offer to Purchase, “Taking Up and Payment for Deposited Shares”.

Withdrawal Rights			Shares deposited pursuant to the Offer may be withdrawn by the Shareholder (a) at any time if the shares have not been taken up by the Company before actual receipt by the Depositary of a notice of withdrawal in respect of such Shares, (b) at any time before the expiration of ten (10) days from the date that a notice of change or variation (unless (i) the variation consists solely of an increase in the consideration offered for those Shares pursuant to the Offer where the time for deposit is not extended for greater than ten (10) days, or (ii) the variation consists solely of the waiver of a condition of the Offer) has been given in accordance with Section 8, “Extension and Variation of the Offer”, or (c) at any time if the Shares have been taken up but not paid for by the Company within three (3) Business Days of being taken up. In addition, pursuant to Rule 13e-4(f) under the Exchange Act, Shares may also be withdrawn after January 3, 2024, which is the 40th Business Day after the date of the commencement of the Offer, unless such Shares have already been accepted for payment by the Company pursuant to the Offer and not validly withdrawn.
Position of the Company and its Directors			Neither the Company nor its Board of Directors makes any recommendation to any Shareholder as to whether to deposit or refrain from depositing Shares. Shareholders are urged to evaluate carefully all information in the Offer, consult their own investment and tax advisors and make their own decisions whether to deposit Shares under the Offer, how many Shares to deposit and whether to specify a price and, if so, at what price to deposit such Shares. See Section 1 of the Offer to Purchase, “The Offer”.

OFFER TO PURCHASE

To the holders of Shares of Imperial Oil Limited:

1.THE OFFER

The Company hereby offers, upon the terms and subject to the conditions described in this Offer to Purchase, the accompanying Circular, the related Letter of Transmittal and the Notice of Guaranteed Delivery, to purchase for cancellation a number of Shares having an aggregate purchase price not exceeding $1,500,000,000 pursuant to:

•Auction Tenders at an Auction Price of not less than $78.50 and not more than $94.00 per Share in increments of $0.25 per Share, as specified by the Shareholders;

•Purchase Price Tenders; or

•Proportionate Tenders.

The Offer will commence on November 3, 2023, the date of this Offer to Purchase, and expire at 5:00 p.m. (Calgary time) on December 8, 2023, or at such later time and date to which the Offer may be extended by Imperial, unless withdrawn. Beneficial owners should be aware that their broker, dealer, commercial bank, trust company or other nominee may establish its own earlier deadlines for participation in the Offer.

THE OFFER IS NOT CONDITIONAL UPON ANY MINIMUM NUMBER OF SHARES BEING DEPOSITED. THE OFFER IS, HOWEVER, SUBJECT TO CERTAIN OTHER CONDITIONS. SEE SECTION 7 OF THE OFFER TO PURCHASE, “CERTAIN CONDITIONS OF THE OFFER”.

Imperial will return all Shares not purchased under the Offer (including Shares not purchased because of proration or invalid tenders and Shares deposited pursuant to Auction Tenders at prices in excess of the Purchase Price), or properly withdrawn before the Expiration Date.

None of Imperial, its Special Committee or its Board of Directors, the Dealer Manager or the Depositary makes any recommendation to any Shareholder as to whether to deposit or refrain from depositing Shares. Shareholders must make their own decisions as to whether to deposit Shares under the Offer, how many Shares to deposit and whether to specify a price and, if so, at what price to deposit such Shares. Shareholders should carefully consider the income tax consequences of having Shares being purchased under to the Offer. See Section 13 of the Circular, “Income Tax Considerations”.

The accompanying Circular, Letter of Transmittal and Notice of Guaranteed Delivery contain important information and should be read carefully before making a decision with respect to the Offer.

2.PURCHASE PRICE

Purchase Price

the Company is 19,108,280 Shares. If the Purchase Price is determined to be $94.00 (which is the maximum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 15,957,446 Shares. For the purpose of determining the Purchase Price, Shares tendered pursuant to a Purchase Price Tender will be considered to have been tendered at a price of $78.50 per Share (which is the minimum price per Share under the Offer). Shares tendered pursuant to a Proportionate Tender will be considered to have been tendered at a price per Share equal to the Purchase Price. Shares tendered by a Shareholder pursuant to an Auction Tender will not be purchased by the Company pursuant to the Offer if the price per Share specified by the Shareholder is greater than the Purchase Price. Shareholders who validly tender Shares without specifying the method in which they are tendering their shares, or who make an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender. Shareholders who wish to deposit Shares without specifying a price at which such Shares may be purchased by the Company should tender Shares in a Purchase Price Tender. Under a Purchase Price Tender, Shares will be purchased, upon the terms and subject to the conditions of the Offer, at the Purchase Price determined as provided herein.

Shareholders should be aware that Shares tendered in Purchase Price Tenders will be deemed to have been tendered at the minimum price of $78.50 per Share and such tenders may result in a lower Purchase Price than might otherwise have been determined.

As promptly as practicable after determining the Purchase Price, Imperial will publicly announce the Purchase Price and all Shareholders who have validly deposited and not withdrawn their shares pursuant to Auction Tenders at or below the Purchase Price or pursuant to Purchase Price Tenders or Proportionate Tenders will receive the Purchase Price, payable in cash, for all Shares purchased upon the terms and subject to the conditions of the Offer, including the provisions relating to proration and the preferential acceptance of odd lots described herein. See Section 3 of this Offer, “Number of Shares, Proration and Proportionate Tenders”.

All Shares purchased by the Company pursuant to the Offer (including Shares at Auction Prices below the Purchase Price) will be purchased at the Purchase Price. All Auction Tenders, Purchase Price Tenders and Proportionate Tenders will be subject to adjustment to avoid the purchase of fractional Shares. Imperial will return all Shares not purchased under the Offer, including Shares not purchased because of proration or invalid tenders or Shares deposited pursuant to Auction Tenders at prices in excess of the Purchase Price, or properly withdrawn before the Expiration Date. All payments to Shareholders will be subject to deduction of applicable withholding taxes.

No alternative, conditional or contingent tenders will be accepted.

Currency

Each registered Shareholder who has tendered Shares under the Offer will receive payment of the Purchase Price for purchased Shares in Canadian dollars, unless such Shareholder exercises the applicable election in the Letter of Transmittal and Notice of Guaranteed Delivery to use the Depositary’s currency exchange services to convert payment of the Purchase Price of the tendered Shares into United States dollars as described below. There is no additional fee payable by Shareholders who elect to use the Depositary’s currency exchange services.

Each non-registered or beneficial Shareholder who has tendered Shares under the Offer will receive payment of the Purchase Price for purchased Shares in Canadian dollars, unless such non-registered Shareholder contacts the intermediary in whose name such Shareholder’s shares are registered and requests that the intermediary make an election on its behalf to receive the Purchase Price in United States dollars as described below.

The exchange rate that will be used to convert payments from Canadian dollars into United States dollars will be the rate available from Computershare Trust Company of Canada, in its capacity as foreign exchange service provider, on the date on which the funds are converted, which rate will be based on the prevailing market rate on such date. The risk of any fluctuations in such rates, including risks relating to the particular date and time at which funds are converted, will be borne solely by the Shareholder. Computershare Trust Company of Canada will act as principal in such currency conversion transactions.

3.NUMBER OF SHARES, PRORATION AND PROPORTIONATE TENDERS

We will purchase, upon the terms and subject to the conditions of the Offer, at the Purchase Price, Deposited Shares up to a maximum aggregate purchase price of $1,500,000,000. The number of Shares that the Company will purchase pursuant to the Offer and the aggregate purchase price will vary depending on whether the Auction Tender Purchase Amount is less than or equal to the Auction Tender Limit Amount. If the Auction Tender

Purchase Amount is less than the Auction Tender Limit Amount, the Company will purchase proportionately fewer Shares and the aggregate purchase price therefor will be proportionately less. If the Auction Tender Purchase Amount is equal to the Auction Tender Limit Amount, the Company will purchase 15,957,446 Shares if the Purchase Price is $94.00 per Share (the maximum price per Share under the Offer) and 19,108,280 Shares if the Purchase Price is $78.50 per Share (the minimum price per Share under the Offer), in both cases for an aggregate purchase price of $1,500,000,000. The Offer is not conditional upon any minimum number of Shares being properly deposited under the Offer.

If the Auction Tender Purchase Amount is less than or equal to the Auction Tender Limit Amount, the Company will purchase at the Purchase Price all Shares so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders. If the Auction Tender Purchase Amount is greater than the Auction Tender Limit Amount, the Company will purchase a portion of the Shares so tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders, as follows: (i) first, the Company will purchase at the Purchase Price all Shares tendered by Odd Lot Holders at or below the Purchase Price; and (ii) second, the Company will purchase at the Purchase Price on a pro rata basis that portion of the Shares tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders having an aggregate purchase price, based on the Purchase Price, equal to (A) the Auction Tender Limit Amount, less (B) the aggregate amount paid by the Company for Shares tendered by Odd Lot Holders. The pro-ration percentage for each individual Shareholder other than Odd Lot Holders within the Auction Tender/Purchase Price Tender pool will be calculated as (1) the number of Shares such Shareholder has tendered at or below the Purchase Price, divided by (2) the total number of Shares tendered pursuant to Auction Tenders (at prices at or below the Purchase Price) and Purchase Price Tenders. Shares that are tendered above the Purchase Price will not be taken into account and will therefore be excluded from the pro-ration calculation.

As set out above, Odd Lots will be accepted for purchase before any proration. In order to qualify for this preference, an Odd Lot Holder must properly tender, pursuant to an Auction Tender at a price at or below the Purchase Price or pursuant to a Purchase Price Tender, all Shares beneficially owned by such Odd Lot Holder. Partial tenders will not qualify for this preference. This preference is not available to holders of 100 or more Shares even if holders have separate share certificates for fewer than 100 Shares or hold fewer than 100 Shares in different accounts. Any Odd Lot Holder wishing to tender all Shares beneficially owned, without proration, must complete the appropriate box on the Letter of Transmittal and, if applicable, on the Notice of Guaranteed Delivery. Shareholders owning an aggregate of fewer than 100 Shares whose Shares are purchased pursuant to the Offer not only will avoid the payment of brokerage commissions, but will also avoid any odd lot discounts, each of which may be applicable on a sale of their Shares in a transaction on the TSX or NYSE American.

Regardless of proration, the Company will always purchase at the Purchase Price a number of the Shares from Shareholders making valid Proportionate Tenders that results in such Shareholders maintaining their respective proportionate Share ownership in the Company following completion of the Offer (subject to nominal differences due to the quantity of Shares purchased from such Shareholders being rounded down to the nearest whole number of Shares to avoid the purchase of fractional Shares). Shareholders making Proportionate Tenders will be prorated in a separate proration pool from Shareholders making Auction Tenders and/or Purchase Price Tenders. Such proration will be based on the number of Shares necessary for such Shareholders to maintain their existing ownership percentages. These proration mechanics are required to permit Proportionate Tenders pursuant to the Offer and differ from the standard mechanics required under applicable securities laws in issuer bids/tender offers without Proportionate Tenders. Imperial has obtained the Proportionate Take Up Relief from the securities regulatory authorities in Canada from the proportionate take up and related disclosure requirements in order to permit Proportionate Tenders to be purchased under the Offer and has applied for exemptive relief from the SEC under Rule 13e-4(f)(3) under the Exchange Act to allow for the proration contemplated by the Offer.

If the Auction Tender Purchase Amount is equal to or greater than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate value equal to $1,500,000,000. If the Auction Tender Purchase Amount is less than the Auction Tender Limit Amount, the Company will repurchase a total number of Shares having an aggregate value equal to the product of (i) $1,500,000,000, and (ii) a fraction, the numerator of which is the Auction Tender Purchase Amount, and the denominator of which is the Auction Tender Limit Amount.

4.ANNOUNCEMENT OF RESULTS OF THE OFFER

The Company will publicly announce the results of the Offer, including the Purchase Price, the number of Shares validly tendered to the Offer and the aggregate purchase price of the Shares to be purchased for cancellation pursuant to the Offer, as promptly as reasonably practicable after the Expiration Date.

5.PROCEDURE FOR DEPOSITING SHARES

Proper Deposit of Shares

Shareholders who wish to accept the Offer may do so by making Auction Tenders, Purchase Price Tenders or Proportionate Tenders. In accordance with Instruction 4 of the Letter of Transmittal, each Shareholder desiring to deposit Shares pursuant to the Offer must indicate (a): in Box A captioned “Type of Tender” on such Letter of Transmittal and, if applicable, the Notice of Guaranteed Delivery, whether Shares are deposited pursuant to an Auction Tender, Purchase Price Tender, or Proportionate Tender; (b) in Box G, if an Auction Tender is made, the price (in increments of $0.25 per Share) at which such Shares are being deposited; (c) in Box B, if a Proportionate Tender is made, the total number of Shares the participating Shareholder owns; and (d) in Box E, if applicable, whether the Shareholder is making an Odd Lot deposit in accordance with Instruction 7 of the Letter of Transmittal.

A Shareholder who wishes to make an Auction Tender will be required to specify, among other things, the number of Shares that it wishes to sell and the price per Share (not less than $78.50 and not more than $94.00 per Share and in increments of $0.25 per Share) at which it is prepared to sell those Shares. A Shareholder may make multiple Auction Tenders but not in respect of the same shares (i.e., Shareholders may deposit different Shares at different prices but cannot deposit the same Shares at different prices). A Shareholder may also make an Auction Tender in respect of certain Shares and a Purchase Price Tender in respect of other Shares. Shareholders who make an Auction Tender or Purchase Price Tender may not make a Proportionate Tender. Odd Lot Holders making an Auction Tender or a Purchase Price Tender will be required to tender all Shares owned by the Shareholder. Proportionate Tenders or partial tenders will not be accepted from Odd Lot Holders.

A Shareholder who wishes to make a Purchase Price Tender or a Proportionate Tender may not specify an Auction Price. A Shareholder who makes a Proportionate Tender will be deemed to have agreed to sell to the Company at the Purchase Price a number of Shares that will result in the Shareholder maintaining its, his or her respective proportionate Share ownership in the Company following completion of the Offer. Registered Shareholders may make a Proportionate Tender and non-registered Shareholders may instruct their nominees to make a Proportionate Tender. All Shareholders who make a Proportionate Tender must state how many Shares they own in the Letter of Transmittal or instruction to their nominee, as the case may be. A registered Shareholder who makes a Proportionate Tender must deposit either all of its Shares or a sufficient number of Shares to satisfy the Shareholder’s Proportionate Tender. The Letter of Transmittal provides guidance on how a registered Shareholder can calculate the minimum number of Shares that would need to be deposited. A non-registered Shareholder who wishes its nominee to make a Proportionate Tender must deposit all of its Shares. If a non-registered Shareholder wishes to become a registered Shareholder in order to make a Proportionate Tender by depositing only a sufficient number of Shares, the Shareholder should immediately contact its investment dealer, stock broker, bank, trust company or other nominee in order to take the necessary steps to have its Shares registered in the Shareholder’s name prior to tendering Shares pursuant to the Offer. A Shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender. Shareholders who make a Proportionate Tender may not make an Auction Tender or a Purchase Price Tender.

Shares deposited pursuant to an Auction Tender in compliance with the procedures set forth herein will be taken up only if the Auction Price specified in the Auction Tender is equal to or less than the Purchase Price.

Shareholders who tender Shares without making a valid Auction Tender, Purchase Price Tender or Proportionate Tender will be deemed to have made a Purchase Price Tender. A shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender. If multiple boxes are checked in the same Letter of Transmittal indicating that Shares are being deposited pursuant to an Auction Tender, Purchase Price Tender, and/or Proportionate Tender, all Shares identified will be deemed to have been tendered pursuant to a Purchase Price Tender.

A shareholder desiring to deposit Shares in separate lots at a different price for each lot must complete a separate Letter of Transmittal (and, if applicable, a separate Notice of Guaranteed Delivery) for each price at which the Shareholder is depositing Shares. The same Shares cannot be deposited pursuant to different tender methods or pursuant to an Auction Tender at more than one price.

Holders of Shares

To deposit Shares pursuant to the Offer, holders of Shares must (a) provide certificates or DRIP position for all Deposited Shares in proper form for transfer, together with a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof), in accordance with the instructions in such Letter of Transmittal, together with all other documents required by the Letter of Transmittal and must be delivered to, and received by, the Depositary at one of the addresses listed in the Letter of Transmittal by the Expiration Date, (b) follow the guaranteed delivery procedure described below, or (c) transfer Shares pursuant to the procedures for book-entry transfer, provided that the Depositary receives at its office in Toronto, Ontario prior to the Expiration Date,

(i)in the case of Shares held by CDS, a Book-Entry Confirmation of transfer of Shares into the Depositary’s account established at CDS in accordance with the terms of the Offer, through the CDSX book-entry system administered by CDS, or (ii) in the case of Shares held in DTC, a message, transmitted by DTC, to and received by the Depositary and forming a part of a DTC book-entry confirmation.

A registered Shareholder who desires to deposit a DRIP position under the Offer must deposit their entire DRIP position, the Shares for which will be removed from the DRIP in connection with such tender, excluding fractions. To the extent a registered Shareholder desires to deposit only a portion of their DRIP position, such Shareholder must withdraw that portion of their DRIP position that they intend to deposit from the DRIP and submit the certificate received in respect thereof, together with a Letter of Transmittal. Shareholders should contact the DRIP plan agent, TSX Trust Company, in such circumstance to arrange the withdrawal.

A non-registered Shareholder who desires to deposit Shares under the Offer should immediately contact such Shareholder’s investment dealer, stock broker, commercial bank, trust company or other nominee in order to take the necessary steps to be able to deposit such Shares under the Offer.

If an investment dealer, stock broker, bank, trust company or other nominee holds Shares for a Shareholder, it is likely the nominee has established an earlier deadline for that Shareholder to act to instruct the nominee to accept the Offer on its behalf. A Shareholder should immediately contact the Shareholder’s investment dealer, stock broker, bank, trust company or other nominee to find out the nominee’s deadline.

Participants of CDS or DTC should contact CDS or DTC, as applicable, to obtain instructions as to the method of depositing Shares under the terms of the Offer. CDS and DTC will be issuing instructions to their respective participants as to the method of depositing Shares under the terms of the Offer.

Imperial Savings Plan Participants

Employee and retiree participants in the Company and select affiliates’ Savings Plan (the “Savings Plan”) who beneficially own Shares under the Savings Plan and who wish to have the Savings Plan administrator tender such Shares should complete the election form available on the participant’s online Savings Plan member website in accordance with the election instructions included with the letter furnished to such participants. The administrator of the Savings Plan will tabulate the results of all such Savings Plan elections and will, or will cause the Savings Plan custodian to, deposit to the Offer one or more Letters of Transmittal reflecting the participants’ elections. The participants in the Savings Plan may not use the Letter of Transmittal to direct the tender of the Savings Plan Shares, but must use the separate election form for participants in the Savings Plan. Savings Plan participants are urged to read the separate election form, the election instructions and related materials carefully. Any Savings Plan Shares tendered but not purchased will be retained in the participant's Savings Plan account.

Participants in the Savings Plan should carefully consider the income tax consequences of having Shares in the Savings Plan purchased under the Offer, which consequences may differ from those that other Shareholders may realize and which consequences may further differ depending upon the Savings Plan account from which such Shares are tendered.

Signature Guarantees

No signature guarantee is required on the Letter of Transmittal if (a) the Letter of Transmittal is signed by the registered holder of the Shares exactly as the name of the registered holder appears on the DRIP position or the share certificate deposited therewith, and payment is to be made directly to such registered holder, or (b) shares are deposited for the account of an Eligible Institution. In all other cases, all signatures on the Letter of Transmittal must be guaranteed by an Eligible Institution. See the appropriate instructions in the Letter of Transmittal.

If a certificate or DRIP position representing Shares is registered in the name of a Person other than the signatory to a Letter of Transmittal, or if payment is to be made, or certificates or DRIP positions representing Shares not purchased are to be issued, to a Person other than the registered holder, the certificate or DRIP position must be endorsed or accompanied by an appropriate stock power, in either case, signed exactly as the name of the registered holder appears on the certificate or DRIP position with the signature on the certificate or stock power signature guaranteed by an Eligible Institution.

Book-Entry Transfer Procedures

An account with respect to the Shares will be established at CDS for purposes of the Offer. Any financial institution that is a participant in CDS may make book-entry delivery of the Shares through CDSX by causing CDS to transfer such Shares into the Depositary’s account in accordance with CDS’s procedures for such transfer. Delivery of Shares to the Depositary by means of a book-entry transfer through CDSX will constitute a valid tender under the Offer.

Shareholders may accept the Offer by following the procedures for a book-entry transfer established by CDS, provided that a Book-Entry Confirmation through CDSX is received by the Depositary at its Toronto, Ontario office address set forth on the back-cover page of this Offer to Purchase and Circular prior to the Expiration Date. Shareholders, through their respective CDS Participants, who utilize CDSX to accept the Offer through a book-entry transfer of their holdings into the Depositary’s account with CDS shall be deemed to have completed and submitted a Letter of Transmittal and to be bound by the terms thereof and, therefore, such instructions received by the Depositary are considered a valid tender in accordance with the terms of the Offer. Delivery of documents to CDS does not constitute delivery to the Depositary.

Shareholders who have an account maintained by DTC may accept the Offer by following the procedures for book-entry transfer established by DTC, provided that a book-entry confirmation, together with an Agent’s Message in respect thereof, or a properly completed and duly executed Letter of Transmittal and any other required documents, are received by the Depositary at its office specified in the Letter of Transmittal prior to the Expiration Date of the Offer. If necessary, the Depositary will establish an account at DTC for the purpose of the Offer. Any financial institution that is a participant in DTC’s systems may cause DTC to make a book-entry transfer of a Shareholder’s Shares into the Depositary’s account in accordance with DTC’s procedures for such transfer. However, as noted above, although delivery of Shares may be effected through book-entry transfer at DTC, either a Letter of Transmittal (or a manually signed facsimile copy thereof), properly completed and duly executed, together with any required signature guarantees, or an Agent’s Message in lieu of a Letter of Transmittal, and any other required documents, must, in any case, be received by the Depositary, at its office specified in the Letter of Transmittal prior to the Expiration Date. Delivery of documents to DTC in accordance with its procedures does not constitute delivery to the Depositary.

Method of Delivery

The method of delivery of certificates representing Shares and all other required documents is at the option and risk of the depositing Shareholder. If certificates representing Shares are to be sent by mail, registered mail that is properly insured is recommended and it is suggested that the mailing be made sufficiently in advance of the Expiration Date to permit delivery to the Depositary on or prior to such date. Delivery of a share certificate representing Shares will only be made upon actual receipt of such share certificate representing Shares by the Depositary.

Lost or Stolen Certificates

If any certificate representing Shares has been lost or destroyed, the Shareholder should promptly notify the Transfer Agent at the phone number or address set forth on the back cover page of this document. The Shareholder will then be instructed as to the steps that must be taken in order to replace the certificate(s). The Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost or destroyed

certificates have been followed, and in such circumstances, a longer period of time may be needed to complete a tender of Shares. Shareholders are urged to contact the Depositary immediately in order to permit timely processing of this documentation.

Procedure for Guaranteed Delivery

If a Shareholder wishes to deposit Shares pursuant to the Offer and cannot deliver certificates for such Shares, or the book-entry transfer procedures described above cannot be completed, prior to the Expiration Date, or time will not permit all required documents to reach the Depositary by the Expiration Date, such Shares may nevertheless be deposited if all of the following conditions are met:

(a)such deposit is made by or through an Eligible Institution, except for any tender by the administrator of the Savings Plan;

(b)a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form provided by the Company through the Depositary is received by the Depositary, at its Toronto office listed in the Notice of Guaranteed Delivery, by the Expiration Date; and

(c)the share certificates for all Shares proposed to be taken up in proper form for transfer, together with a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof) or, in the case of a book-entry transfer, a Book-Entry Confirmation through CDSX (in the case of Shares held in CDS) or an Agent’s Message (in the case of Shares held in DTC), and any other documents required by the Letter of Transmittal, are received by the Toronto office of the Depositary, before 5:00 p.m. (Calgary time) on or before the second trading day on the TSX after the Expiration Date.

The Notice of Guaranteed Delivery may be hand delivered, couriered, mailed or transmitted by electronic mail transmission to the Toronto office of the Depositary listed in the Notice of Guaranteed Delivery, and must include a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery.

Notwithstanding any other provision hereof, payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of the share certificates for all Shares proposed to be taken up in proper form for transfer, together with a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof) or Book-Entry Confirmation in lieu thereof relating to such Shares, with signatures that are guaranteed if so required in accordance with the Letter of Transmittal, and any other documents required by the Letter of Transmittal.

The tender information specified in a Notice of Guaranteed Delivery by a Person completing such Notice of Guaranteed Delivery will, in all circumstances, take precedence over the tender information that is specified in the related Letter of Transmittal that is subsequently deposited.

Return of Unpurchased Shares

All tendered Shares not purchased, including all Shares tendered pursuant to Auction Tenders at prices greater than the Purchase Price, Shares not purchased due to pro-ration and Shares not accepted for purchase, will be returned to the tendering Shareholder promptly after the Expiration Date or termination of the Offer without expense to the tendering Shareholder.

In the case of Shares tendered through book-entry transfer into the Depositary’s account at DTC or CDS, the Shares will be credited to the appropriate account maintained by the tendering Shareholder at DTC or CDS, as applicable, without expense to the Shareholder.

Determination of Validity, Rejection and Notice of Defect

All questions as to the number of tenders to be accepted, the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any Shares will be determined by the Company, in its sole discretion, which determination shall be final and binding on all parties. Imperial reserves the absolute right to reject any deposits of Shares determined by it not to be in proper form or completed in accordance with the instructions herein and in the Letter of Transmittal or the acceptance for payment of or payment for which may, in the opinion of the Company’s counsel, be unlawful. Imperial also reserves the absolute right to waive any of the conditions of the

Offer or any defect or irregularity in the deposit of any particular Shares, and Imperial’s interpretation of the terms of the Offer (including these instructions) will be final and binding on all parties. No individual deposit of Shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with deposits must be cured within such time as Imperial shall determine. None of Imperial, the Depositary, the Dealer Manager nor any other Person is or will be obligated to give notice of defects or irregularities in deposits, nor shall any of them incur any liability for failure to give any such notice. The Company’s interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and the Notice of Guaranteed Delivery) will be final and binding.

Under no circumstances will interest be paid by the Company or the Depositary by reason of any delay in making payment to any Person using the guaranteed delivery procedures, including without limitation any delay arising because the Shares to be delivered pursuant to the guaranteed delivery procedures are not so delivered to the Depositary, and therefore payment by the Depositary on account of such Shares is not made until after the date the payment for the Deposited Shares taken up pursuant to the Offer is to be made by the Company.

Formation of Agreement

The proper deposit of Shares pursuant to any one of the procedures described above will constitute a binding agreement between the depositing Shareholder and the Company, effective as of the Expiration Date, upon the terms and subject to the conditions of the Offer. Such agreement will be governed by and construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein.

Prohibition on “Short” Tenders

It is a violation of Rule 14e-4 promulgated under the Exchange Act for a Person acting alone or in concert with others, directly or indirectly, to tender shares for such Person’s own account unless at the time of tender and at the Expiration Date such Person has a “net long position” in (i) a number of shares that is equal to or greater than the amount tendered and will deliver or cause to be delivered such shares for the purpose of tendering to us within the period specified in the Offer or (ii) other securities immediately convertible into, exercisable for or exchangeable into a number of shares (“Equivalent Securities”) that is equal to or greater than the number of shares tendered and, upon the acceptance of such tender, will acquire such shares by conversion, exchange, or exercise of such Equivalent Securities to the extent required by the terms of the Offer and will deliver or cause to be delivered such shares so acquired for the purpose of tender to us within the period specified in the Offer. Rule 14e-4 also provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another Person. A tender of shares made pursuant to any method of delivery set forth in the Circular will constitute the tendering shareholder’s acceptance of the terms and conditions of the Offer, as well as the tendering shareholder’s representation and warranty to us that (i) such shareholder has a “net long position” in a number of shares or Equivalent Securities at least equal to the shares being tendered within the meaning of Rule 14e-4, and (ii) such tender of shares complies with Rule 14e-4. Our acceptance for payment of shares tendered pursuant to the Offer will constitute a binding agreement between the tendering shareholder and us upon the terms and subject to the conditions of the Offer.

Further Assurances

Each Shareholder accepting the Offer covenants under the terms of the Letter of Transmittal to execute, upon request of Imperial, any additional documents, transfers and other assurances as may be necessary or desirable to complete the sale, assignment and transfer of any Shares proposed to be taken up by the Company. Each authority therein conferred or agreed to be conferred may be exercised during any subsequent legal incapacity of such Shareholder and shall, to the extent permitted by law, survive the death or incapacity, bankruptcy or insolvency of the Shareholder and all obligations of the Shareholder therein shall be binding upon the heirs, personal representatives, successors and assigns of such Shareholder.

6.WITHDRAWAL RIGHTS

Except as otherwise provided in this Section, deposits of Shares pursuant to the Offer will be irrevocable. Shares deposited pursuant to the Offer may be withdrawn by the Shareholder (a) at any time if the Shares have not been taken up by the Company before actual receipt by the Depositary of a notice of withdrawal in respect of such shares, (b) at any time before the expiration of ten (10) days from the date that a notice of change or variation (unless

(i) the variation consists solely of an increase in the consideration offered for those Shares pursuant to the Offer where the time for deposit is not extended for greater than ten (10) days, or (ii) the variation consists solely of the waiver of a condition of the Offer) has been given in accordance with Section 8, “Extension and Variation of the Offer”; or (c) at any time if the Shares have been taken up but not paid for by the Company within three (3) Business

Days of being taken up. In addition, pursuant to Rule 13e-4(f) under the Exchange Act, Shares may also be withdrawn after January 3, 2024, which is the 40th Business Day after the date of the commencement of the Offer, unless such Shares have already been accepted for payment by the Company pursuant to the Offer and not validly withdrawn.

For a withdrawal to be effective, a written or printed copy of a notice of withdrawal must be actually received by the Depositary by the applicable date specified above at the place of deposit of the relevant Shares. Any such notice of withdrawal must be signed by or on behalf of the Person who signed the Letter of Transmittal or Notice of Guaranteed Delivery in respect of the Shares being withdrawn or, in the case of shares tendered by a CDS Participant through CDSX, be signed by such participant in the same manner as the participant’s name is listed on the applicable Book- Entry Confirmation or, in the case of Shares tendered by a DTC participant, be signed by such participant in the same manner as the participant’s name is listed on the applicable Agent’s Message, and must specify the name of the Person who deposited the shares to be withdrawn, the name of the registered holder, if different from that of the Person who deposited such shares, and the number of shares to be withdrawn. If the certificates for the Shares deposited pursuant to the Offer have been delivered or otherwise identified to the Depositary, then, prior to the release of such certificates, the depositing Shareholder must submit the serial numbers shown on the particular certificates evidencing the shares to be withdrawn and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”), except in the case of shares deposited by an Eligible Institution. A withdrawal of Shares deposited pursuant to the Offer may only be accomplished in accordance with the foregoing procedure. The withdrawal shall take effect only upon actual receipt by the Depositary of a written or printed copy of a properly completed and executed notice of withdrawal.

A Shareholder who wishes to withdraw Shares under the Offer and who holds Shares through an investment dealer, stock broker, bank, trust company or other nominee should immediately contact such nominee in order to take the necessary steps to be able to withdraw such Shares under the Offer. Participants of CDS or DTC should contact these depositaries with respect to the withdrawal of Shares under the Offer.

All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by the Company, in its sole discretion, which determination shall be final and binding. None of the Company, the Depositary, the Dealer Manager or any other Person shall be obligated to give any notice of any defects or irregularities in any notice of withdrawal and none of them shall incur any liability for failure to give any such notice.

Any Shares properly withdrawn will thereafter be deemed not deposited for purposes of the Offer. However, withdrawn shares may be redeposited prior to the Expiration Date by again following the procedures described in Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”.

If the Company extends the period of time during which the Offer is open, is delayed in its purchase of Shares or is unable to purchase Shares pursuant to the Offer for any reason, then, without prejudice to the Company’s rights under the Offer, the Depositary may, subject to applicable law, retain on behalf of the Company all Deposited Shares, and such Shares may not be withdrawn except to the extent that depositing Shareholders are entitled to withdrawal rights as described in this Section.

7.CERTAIN CONDITIONS OF THE OFFER

Notwithstanding any other provision of the Offer, the Company shall not be required to accept for purchase, to purchase or, subject to any applicable rules or regulations, to pay for any Shares deposited, and may terminate, cancel or amend the Offer or may postpone the payment for Shares deposited, if, at any time before the Expiration Date, any of the following events shall have occurred (or shall have been determined by the Company to have occurred) which, in the Company’s sole judgment, acting reasonably, in any such case, makes it inadvisable to proceed with the Offer or with such acceptance for purchase or payment:

(f)the Company shall have concluded, in its sole judgment, acting reasonably, that the Offer or the take up and payment for any or all of the Shares by the Company is illegal or not in compliance with applicable law, or that necessary exemptions under applicable securities legislation, including exemptions from proportionate take up and related disclosure requirements and from the obligation to take up Shares in the event that the Offer is extended in certain circumstances applied for by the Company from the securities regulatory authorities in Canada and the SEC, are not available to the Company for the Offer and, if required under any such legislation, the Company shall not have received the necessary exemptions from or waivers of the appropriate courts or securities regulatory authorities in respect of the Offer, including the Securities Regulatory Relief, or such exemptions or waivers are rescinded or modified in a manner that is not in form and substance satisfactory to the Company;

(g)any changes shall have occurred or been proposed to the Tax Act or the Code, to the publicly available administrative policies or assessing practices of the CRA or the IRS or to relevant tax jurisprudence that, in the sole judgment of the Company are detrimental to Imperial or its affiliates taken as a whole or any one or more Shareholders, or with respect to making the Offer or taking up and paying for Shares deposited under the Offer;

(h)RBC Capital Markets shall have withdrawn or amended the Liquidity Opinion provided by it in connection with the Offer;

The foregoing conditions are for the sole benefit of the Company and may be asserted by the Company in its sole discretion, acting reasonably, or may be waived by the Company, in its sole discretion, in whole or in part at any time, provided that the conditions listed in clause (i) above are not waivable by the Company. Any determination by the Company concerning the events described in this Section 7 shall be final and binding on all parties.

Any waiver of a condition or the withdrawal of the Offer by Imperial shall be deemed to be effective on the date on which notice of such waiver or withdrawal by the Company is delivered or otherwise communicated to the Depositary. Imperial, after giving notice to the Depositary of any waiver of a condition or the withdrawal of the Offer, shall immediately make a public announcement of such waiver or withdrawal and provide or cause to be provided notice of such waiver or withdrawal to the TSX, NYSE American and the applicable Canadian securities regulatory authorities. If the Offer is withdrawn, the Company shall not be obligated to take up, accept for purchase or pay for any Shares deposited under the Offer, and the Depositary will return all certificates or DRIP positions for Deposited Shares, Letters of Transmittal and Notices of Guaranteed Delivery and any related documents to the parties by whom they were deposited.

8.EXTENSION AND VARIATION OF THE OFFER

Subject to applicable law, the Company expressly reserves the right, in its sole discretion, and regardless of whether or not any of the conditions specified in Section 7 of this Offer to Purchase. “Certain Conditions of the Offer” shall have occurred, at any time or from time to time, to extend the period of time during which the Offer is open or to vary the terms and conditions of the Offer by giving written notice, or oral notice to be confirmed in writing, of extension or variation to the Depositary and by causing the Depositary to provide to all Shareholders, where required by law, as soon as practicable thereafter, a copy of the notice in the manner set forth in Section 12 of this Offer to Purchase, “Notice”. Promptly after giving notice of an extension or variation to the Depositary, but, in the case of an extension, no later than 9:00 a.m. (Calgary time) on the next Business Day following the last previously scheduled or announced Expiration Date, the Company will make a public announcement of the extension or variation and provide or cause to be provided notice of such extension or variation to the TSX, NYSE American and the applicable Canadian securities regulatory authorities. Any notice of extension or variation will be deemed to have been given and be effective on the day on which it is delivered or otherwise communicated to the Depositary at its principal office in Calgary, Alberta.

If we make a material change in the terms of the Offer or the information concerning the Offer or if we waive a material condition of the Offer, we will disseminate additional tender offer materials and extend the Offer if and to the extent required by applicable Canadian securities laws, the rules of the SEC under the Exchange Act and the

interpretations thereunder. Pursuant to applicable United States securities laws, the minimum period during which an offer must remain open following material changes in the terms of an offer or information concerning an offer, other than a change in price or a change in percentage of securities sought, will depend upon the facts and circumstances, including the relative materiality of the terms or information changes and the appropriate manner of dissemination. In a published release, the SEC has stated that, in its view, an offer should remain open for a minimum of five business days from the date the material change is first published, sent or given to security holders, and that if material changes are made with respect to information that approaches the significance of price and the percentage of securities sought, a minimum period of ten business days may be required to allow for adequate dissemination to security holders and investor response. During any such extension or in the event of any variation, all Shares previously deposited and not taken up or withdrawn will remain subject to the Offer and may be accepted for purchase by the Company in accordance with the terms of the Offer, subject to Section 6 of this Offer to Purchase, “Withdrawal Rights”. An extension of the Expiration Date or a variation of the Offer does not constitute a waiver by the Company of its rights in Section 7 of this Offer to Purchase, “Certain Conditions of the Offer”.

If the Company makes a material change in the terms of the Offer or the information concerning the Offer, the Company will extend the time during which the Offer is open to the extent required under applicable Canadian and United States securities laws and regulations.

In order to facilitate the availability of Proportionate Tenders pursuant to the Offer, Imperial has obtained the Extension Relief to permit Imperial to extend the Offer, in circumstances in which all of the terms and conditions of the Offer have either been satisfied or waived by Imperial, without first taking up Shares which have been deposited (and not withdrawn) before the Offer was previously scheduled to expire. Accordingly, in the event that Imperial elects to extend the Offer, Imperial will not take up or pay for any Shares until the expiry of such extension.

The Company also expressly reserves the right, in its sole discretion, (a) to terminate the Offer and not take up and pay for any Shares not theretofore taken up and paid for upon the occurrence of any of the conditions specified in Section 7 of this Offer to Purchase, “Certain Conditions of the Offer”, and/or (b) at any time or from time to time, to vary the Offer in any respect, including increasing or decreasing the aggregate purchase price for Shares that the Company may purchase or the range of prices it may pay pursuant to the Offer, subject to compliance with applicable Canadian and United States securities laws and regulations.

Any such extension, delay, termination or variation will be followed as promptly as practicable by a public announcement. Without limiting the manner in which the Company may choose to make any public announcement, except as provided by applicable law, the Company shall have no obligation to publish, advertise or otherwise communicate any such public announcement other than by making a release through a widely circulated news wire service.

9.TAKING UP AND PAYMENT FOR DEPOSITED SHARES

The Company will comply with both Canadian and U.S. regulations governing the timing for acceptance of and payment for Shares. Under Canadian regulations, upon the terms and provisions of the Offer (including proration) and subject to and in accordance with applicable securities laws, the Company is required to take up and pay for Shares properly deposited and not withdrawn under the Offer in accordance with the terms thereof as soon as practicable after the Expiration Date, but in any event not later than ten days after the Expiration Date, provided that the conditions of the Offer (as the same may be varied) have been satisfied or waived. Any Shares taken up must be paid for as soon as reasonably practicable, but in any event no later than three (3) Business Days after they are taken up in accordance with applicable Canadian securities laws. Pursuant to Rule 14e-1(c) under the Exchange Act, the Company is required to promptly accept for payment and promptly thereafter pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Date pursuant to the Offer.

The Company currently expects to accept and pay for Shares validly tendered and not validly withdrawn prior to the Expiration Date on December 13, 2023, the 3rd Business Day following the Expiration Date (assuming the Expiration Date is not extended beyond December 8, 2023).

For the purpose of the Offer, the Company will be deemed to have taken up and accepted for payment validly tendered Shares having an aggregate Purchase Price not exceeding $1,500,000,000 if, as and when the Company gives written notice or other communication confirmed in writing to the Depositary to that effect.

The Company reserves the right, in its sole discretion, to delay taking up or paying for any Shares or to terminate the Offer and not take up or pay for any Shares upon the occurrence of any of the conditions specified in Section 7 of this Offer to Purchase by giving written notice thereof or other communication confirmed in writing to the

Depositary. The Company also reserves the right, in its sole discretion and notwithstanding any other condition of the Offer, to delay taking up and paying for Shares in order to comply, in whole or in part, with any applicable law or as permitted pursuant to the Extension Relief.

In the event of proration of Shares deposited pursuant to the Auction Tenders and Purchase Price Tenders, the Company will determine the proration factor and pay for those Deposited Shares accepted for payment as soon as practicable after the Expiration Date. However, the Company does not expect to be able to announce the final results of any such proration until approximately three (3) Business Days after the Expiration Date.

Certificates for all Shares not purchased, including Shares not purchased due to proration and Shares deposited pursuant to Auction Tenders at prices in excess of the Purchase Price, will be returned (in the case of certificates representing Shares all of which are not purchased), or replaced with new certificates representing the balance of Shares not purchased (in the case of certificates representing Shares of which less than all are purchased), as soon as practicable after the Expiration Date or termination of the Offer without expense to the depositing Shareholder. DRIP positions not purchased, including DRIP positions not purchased due to proration and DRIP positions deposited pursuant to Auction Tenders at prices in excess of the Purchase Price, will be returned to the DRIP account as soon as practicable after the Expiration Date or termination of the Offer without expense to the depositing Shareholder.

The Company will pay for Shares taken up under the Offer by providing the Depositary with sufficient funds (by bank transfer or other means satisfactory to the Depositary) for transmittal to depositing Shareholders. Under no circumstances will interest accrue or be paid by the Company or the Depositary on the Purchase Price of the Shares purchased by the Company, regardless of any delay in making such payment or otherwise.

Depositing Shareholders will not be obligated to pay brokerage fees or commissions to the Company or the Depositary. However, Shareholders are cautioned to consult with their own brokers or other intermediaries to determine whether any fees or commissions are payable to their brokers or other intermediaries in connection with a deposit of Shares pursuant to the Offer. Imperial will pay all fees and expenses of the Dealer Managers (in their capacity as such) and the Depositary in connection with the Offer.

The Depositary will act as agent of Persons who have properly deposited Shares under the Offer and have not properly withdrawn them, for the purposes of receiving payment from the Company and transmitting payment to such Persons. Receipt by the Depositary from Imperial of payment for such Shares will be deemed to constitute receipt of payment by Persons depositing Shares. Under no circumstances will interest accrue or be paid by the Company or the Depositary on the Purchase Price to any Person depositing Shares regardless of any delay in making payment, including any delay in making payment to any Person using the guaranteed delivery procedures.

Unless a Shareholder elects to be paid by wire transfer, the settlement with each Shareholder who has deposited Shares under the Offer will be effected by the Depositary by forwarding a cheque, representing the cash payment (subject to applicable withholding taxes, if any) for such Shareholder’s Shares taken up under the Offer. The cheque will be issued in the name of the Person as specified by properly completing the appropriate box in the Letter of Transmittal. Unless the depositing Shareholder instructs the Depositary to hold the cheque for pick-up by checking the appropriate box in the Letter of Transmittal, the cheque will be forwarded by first class mail, postage prepaid, to the payee at the address specified in the Letter of Transmittal. If no such address is specified, the cheque will be sent to the address of the depositing Shareholder as it appears in the registers maintained in respect of the Shares. Cheques mailed in accordance with this paragraph will be deemed to have been delivered at the time of mailing. Payments will be made net of any applicable withholding taxes. Alternatively, a Shareholder may request that the payment for such Shareholder’s Shares taken up under the Offer be paid by wire payment by properly completing the appropriate box in the Letter of Transmittal. Wire payments will be made net of applicable banking fees.

All Shares purchased by the Company pursuant to the Offer will be cancelled.

10.PAYMENT IN THE EVENT OF MAIL SERVICE INTERRUPTION

Notwithstanding the provisions of the Offer, cheques in payment for Shares purchased under the Offer and certificates for any Shares to be returned will not be mailed if the Company determines that delivery by mail may be delayed. Persons entitled to cheques or certificates that are not mailed for this reason may take delivery at the office of the Depositary at which the deposited certificates for the Shares were delivered until the Company has determined that delivery by mail will no longer be delayed. Imperial will provide notice, in accordance with Section 12 of this Offer

to Purchase, of any determination not to mail under this Section 10 as soon as reasonably practicable after such determination is made.

11.LIENS AND DIVIDENDS

Shares acquired pursuant to the Offer shall be acquired by the Company free and clear of all liens, charges, encumbrances, security interests, claims, restrictions and equities whatsoever, together with all rights and benefits arising therefrom, provided that any dividends or distributions that may be paid, issued, distributed, made or transferred on or in respect of such Shares to Shareholders of record on or prior to the date upon which the Shares are taken up and paid for under the Offer shall be for the account of such Shareholders. Each Shareholder of record on that date will be entitled to receive that dividend or distribution whether or not such Shareholder deposits Shares pursuant to the Offer.

12.NOTICE

Without limiting any other lawful means of giving notice, any notice to be given by the Company or the Depositary under the Offer will be deemed to have been properly given if it is mailed by first-class mail, postage prepaid, to the registered holders of Shares at their respective addresses as shown on the share registers maintained in respect of the Shares and will be deemed to have been received on the first Business Day following the date of mailing. These provisions apply despite (i) any accidental omission to give notice to any one or more Shareholders, and (ii) an interruption of mail service following mailing. In the event of an interruption of mail service following mailing, the Company will use reasonable efforts to disseminate the notice by other means, such as publication. If post offices are not open for deposit of mail, or there is reason to believe there is or could be a disruption in all or any part of the postal service, any notice which the Company or the Depositary may give or cause to be given under the Offer will be deemed to have been properly given and to have been received by Shareholders if it is issued by way of a news release and if it is published once in The Globe and Mail or the National Post and in a French language daily newspaper of general circulation in the Province of Québec and in The Wall Street Journal.

13.OTHER TERMS

No broker, dealer or other Person has been authorized to give any information or to make any representation on behalf of the Company other than as contained in the Offer, and, if any such information or representation is given or made, it must not be relied upon as having been authorized by the Company.

It is a term of the Offer that for the purposes of subsection 191(4) of the Tax Act, the “specified amount” in respect of each Share shall be an amount equal to the closing trading price for the Shares on the TSX on the Expiration Date. The Company will publicly announce the specified amount when the Company announces the Purchase Price as promptly as practicable following the Expiration Date.

Shareholders should carefully consider the income tax consequences of accepting the Offer. See Section 13 of the Circular, “Income Tax Considerations”.

The Offer and all contracts resulting from the acceptance thereof shall be governed by and construed in accordance with the laws of the Province of Alberta and the laws of Canada applicable therein.

The Company, in its sole discretion, shall be entitled to make a final and binding determination of all questions relating to the interpretation of the Offer, the validity of any acceptance of the Offer and the validity of any withdrawals of Shares. The Offer is not being made to Shareholders residing in any jurisdiction in which the making of the Offer or the acceptance thereof would not be in compliance with the laws of such jurisdiction.

Imperial has applied for the Securities Regulatory Relief in order to facilitate the availability of Proportionate Tenders pursuant to the Offer and to permit the Company to extend the Offer without first taking up validly deposited Shares in certain circumstances.

ISSUER BID CIRCULAR

This Circular is being furnished in connection with the Offer by Imperial to purchase for cancellation a number of Shares for an aggregate purchase price not exceeding $1,500,000,000 at a Purchase Price of not less than $78.50 per Share and not more than $94.00 per Share. Terms defined in the Offer to Purchase and not otherwise defined herein have the same meaning in this Circular. The terms and conditions of the Offer to Purchase, Letter of Transmittal and the Notice of Guaranteed Delivery are incorporated into and form part of this Circular. Reference is made to the Offer to Purchase for details of its terms and conditions.

1.IMPERIAL OIL LIMITED

Imperial Oil Limited was incorporated under the laws of Canada in 1880 and was continued under the Canada Business Corporations Act by certificate of continuance dated April 24, 1978. The head and principal office of the company is located at 505 Quarry Park Boulevard S.E., Calgary, Alberta, Canada T2C 5N1.

The Company is one of Canada’s largest integrated oil companies. It is active in all phases of the petroleum industry in Canada, including the exploration for, and production and sale of, crude oil and natural gas. In Canada, it is a major producer of crude oil, the largest petroleum refiner and a leading marketer of petroleum products and a major producer of petrochemicals. The Company also pursues lower-emission business opportunities, including carbon capture and storage and biofuels. It is also a major producer of petrochemicals. The Company’s operations are conducted in three main segments: Upstream, Downstream and Chemical.

Imperial is subject to the information and reporting requirements of Canadian provincial and territorial securities laws, and the rules of the TSX, as well as information requirements of the Exchange Act, and in accordance therewith files periodic reports and other information with securities regulatory authorities in Canada, the TSX and the SEC, relating to its business, financial condition and other matters. Shareholders may access documents on SEDAR+’s website at www.sedarplus.ca and on the SEC’s EDGAR website at www.sec.gov.

Imperial has filed with the SEC an Issuer Tender Offer Statement on Schedule TO which contains additional information with respect to the Offer. The Offer, which constitutes a part of the Schedule TO, does not contain all of the information set forth in the Schedule TO.

2.AUTHORIZED CAPITAL

The Company’s authorized share capital consists of 1,100,000,000 Shares. As at October 30, 2023, 554,945,083 Shares were issued and outstanding.

3.PURPOSE AND EFFECT OF THE OFFER

The Board of Directors believes that the purchase of Shares by the Company is in the best interests of the Company and its Shareholders.

The Offer will allow the Company to return up to an additional $1,500,000,000 of capital to Shareholders who elect to tender their shares while at the same time increasing the Share ownership of Shareholders who elect not to tender.

As of October 30, 2023, there were 554,945,083 Shares issued and outstanding. Accordingly, the Offer is for approximately 3.4% of the total number of issued and outstanding Shares if the Purchase Price is determined to be $78.50 (which is the minimum price per Share under the Offer) or approximately 2.9% of the total number of issued and outstanding Shares if the Purchase Price is determined to be $94.00 (which is the maximum price per Share under the Offer). Assuming that the Offer is fully subscribed, the effect of the Offer would be to increase the Share ownership of each Shareholder who does not tender any Shares to the Offer by 3.6% if the Purchase Price is determined to be $78.50 (which is the minimum price per Share under the Offer) or 3.0% if the Purchase Price is determined to be $94.00 (which is the maximum price per Share under the Offer).

Shares acquired by the Company pursuant to the Offer will be cancelled.

Canadian securities laws prohibit the Company and its affiliates from acquiring or offering to acquire beneficial ownership of any Shares, other than pursuant to the Offer, until at least 20 Business Days after the Expiration Date or termination of the Offer, except, in the case of acquisitions during the period following the Expiration Date, pursuant to certain acquisitions effected in the normal course on a published market or as otherwise permitted by applicable law.

Background to the Offer

Management and the Board of Directors continually evaluate the capital allocation of the Company. Consistent with the Company’s balance sheet strength, low capital requirements and strong cash generation, the Company has for a number of years implemented a share repurchase program pursuant to a normal course issuer bid through the facilities of the TSX, repurchasing over 292 million Shares for aggregate consideration of approximately $15,186 million since the Company recommenced its normal course issuer bid program in 2017. Purchases from ExxonMobil are included in this amount, as ExxonMobil was permitted to sell Shares to the Company

outside of, but concurrent with, the normal course issuer bid to maintain its proportionate share ownership interest at approximately 69.6%.

The Company’s two most recent normal course issuer bids resulted in the repurchase of an aggregate of 61,041,444 Shares for total consideration of approximately $4,245 million, as follows:

•2022 NCIB – Commenced June 29, 2022, authorizing the repurchase of up to 31,833,809 Shares over the following twelve months. On July 29, 2022, the Company announced that it intended to accelerate its Share purchases under the normal course issuer bid, and all possible purchases were completed by October 21, 2022, for total consideration of approximately $1,945 million.

•2023 NCIB - Commenced June 29, 2023, authorizing the repurchase of up to 29,207,635 Shares over the following twelve months. On July 28, 2023, the Company announced that it intended to accelerate its Share purchases under the normal course issuer bid, and all possible purchases were completed by October 19, 2023, for total consideration of approximately $2,300 million.

Recognizing the Company’s priority to return cash to Shareholders and in addition to its normal course issuer bids, the Company also announced on April 29, 2022 its intention to launch a substantial issuer bid for up to $2.5 billion. On May 6, 2022, the Company commenced the substantial issuer bid pursuant to which it offered to purchase for cancellation up to $2.5 billion of its Shares through a modified Dutch auction and proportionate tender offer. The Q2 2022 SIB expired on June 10, 2022, with the Company repurchasing and cancelling a total of 32,467,532 Shares at a price of $77.00 per share, for total consideration of $2.5 billion. This included 22,597,379 Shares purchased from ExxonMobil by way of a proportionate tender to maintain its ownership percentage at approximately 69.6% of all issued and outstanding Shares.

Additionally, on October 28, 2022, the Company announced its intention to launch a substantial issuer bid for up to $1.5 billion. On November 4, 2022, the Company commenced the substantial issuer bid pursuant to which it offered to purchase for cancellation up to $1.5 billion of its Shares through a modified Dutch auction and proportionate tender offer. The Q4 2022 SIB expired on December 9, 2022, with the Company repurchasing and cancelling a total of 20,689,655 Shares at a price of $72.50 per share, for total consideration of $1.5 billion. This included 14,399,985 Shares purchased from ExxonMobil by way of a proportionate tender to maintain its ownership percentage at approximately 69.6% of all issued and outstanding Shares.

The Company continually assesses its capacity to return cash to its Shareholders on an efficient basis. At a meeting of the Board of Directors held on September 20, 2023, the Board of Directors reviewed the Company’s most recent update of the corporate and financing plan, which highlighted the strong cash position of the Company and projected cash flow across a variety of crude price scenarios. After giving consideration to, among other things, the capital requirements and financial resources of the Company, it was proposed that the Company consider repurchasing more of its Shares pursuant to another substantial issuer bid. In light of the interest that certain directors of the Company may have as a result of their current or prior involvement with the Principal Shareholder, the Board of Directors mandated a Special Committee composed of independent directors, namely David W. Cornhill (Chair), Sharon R. Driscoll, John Floren, Gary J. Goldberg and Miranda C. Hubbs to further explore the possibility of implementing the substantial issuer bid. Following the meeting, the Special Committee tasked management to complete further analysis and to discuss with outside advisors in order to assist the Board of Directors in making a determination regarding the feasibility and desirability of pursuing a subsequent substantial issuer bid. The Special Committee further considered the proposed substantial issuer bid and whether it would be in the best interests of the Company. Among other things, the Special Committee held discussions and meetings with management of the Company. RBC Capital Markets was engaged to provide capital markets advice and a liquidity opinion in connection with the Offer.

At a meeting of the Special Committee held on October 13, 2023, the Special Committee further considered the possibility of pursuing the proposed substantial issuer bid in a discussion led by RBC Capital Markets, as financial advisor.

At a meeting of the Board of Directors held on October 26, 2023, RBC Capital Markets provided advice to the Board of Directors, including with respect to the trading liquidity of the Shares, and the Special Committee presented its unanimous recommendation to the Board of Directors to proceed with a substantial issuer bid based on certain price and size parameters and to authorize the announcement by the Company of its intention to make such a subsequent substantial issuer bid. At the same meeting, the Board of Directors, based on the unanimous recommendation of the Special Committee and after giving careful consideration to the factors set forth below, unanimously determined that the substantial issuer bid was in the best interests of the Company and its Shareholders and approved the making of such a substantial issuer bid, including the terms, conditions and parameters of the Offer, and the delivery of the Circular to Imperial’s Shareholders. Thereafter, pursuant to authority delegated by the Board of Directors, the Chairman, President and Chief Executive Officer and the Senior Vice-President, Finance and Administration of the Company determined the specific price range and remaining final terms of the Offer within parameters established by the Board of Directors, and RBC Capital Markets delivered its Liquidity Opinion.

In evaluating the Offer and determining that it would be in the best interests of the Company, the Special Committee and the Board of Directors gave careful consideration to a number of factors, including, without limitation, the following:

(a)the Offer represented an opportunity for the Company to return up to $1,500,000,000 of capital to Shareholders who elect to tender, while increasing the proportionate ownership interest of Shareholders who elect not to tender;

(b)the deposit of Shares under the Offer is optional, the option is available to all Shareholders, and all Shareholders are free to accept or reject the Offer;

(c)the positive impact that the purchase of Shares would have on the Company’s earnings and cash flow calculated on a per Share basis, as well as on the return on equity on the Shares;

(d)the Offer reduces the Company’s Share count and therefore the Company’s required cash outlay at any given dividend;

(e)the repurchase of Shares represents an attractive investment and an appropriate and desirable use of available funds;

(f)the Company’s belief that the Offer is a prudent use of the Company’s financial resources given its balance sheet strength, low capital requirements and strong cash generation;

(g)after giving effect to the Offer, the Company will continue to have sufficient financial resources and working capital to conduct its ongoing business and operations and the Offer is not expected to preclude Imperial from pursuing its foreseeable business opportunities or the future growth of the Company’s business;

(h)the advice of the Company’s financial advisor, RBC Capital Markets, in respect of the Offer, including regarding the liquidity of the market for the Shares immediately prior to and after completion of the Offer, and the advice of RBC Capital Markets that it would be in a position to render the Liquidity Opinion upon the Company’s determination of the specific price range and remaining final terms of the Offer;

(i)the fact that it is reasonable to conclude that, following the completion of the Offer in accordance with its terms, there will be a market for holders of Shares who do not tender to the Offer that is not materially less liquid than the market that existed at the time of the making of the Offer (see “Liquidity of Market” below);

(j)the stated intention of the Principal Shareholder to make a Proportionate Tender and the implications thereof, including the fact that the number of Shares to be purchased pursuant to Proportionate Tenders will be dependent upon the number of Shares to be purchased from Auction Tenders and Purchase Price Tenders; and the fact that the Proportionate Tenders will ensure that the public float is not disproportionately reduced as a result of the Offer;

(k)the Offer provides Shareholders with an opportunity to realize on all or a portion of their investment in the Company should they desire liquidity in quantities and at prices which may otherwise be unavailable in the market and (i) to determine the price at which they are willing to sell their Shares if such Shares are tendered pursuant to an Auction Tender or (ii) tender their Shares without specifying a price if such Shares are deposited pursuant to a Purchase Price Tender and, in each case, to sell their Shares without incurring brokerage commissions which might otherwise be payable on a sale of their Shares in a transaction on the TSX or the NYSE American;

(l)Shareholders wishing to tender Shares may do so pursuant to Auction Tenders, Purchase Price Tenders or Proportionate Tenders or by tendering a portion of Shares pursuant to Auction Tenders and another portion of Shares pursuant to Purchase Price Tenders;

(m)the Offer provides Shareholders who are considering the sale of all or a portion of their Shares with the opportunity to sell such Shares for cash without the usual transaction costs associated with market sales;

(n)the Offer is not conditional on any minimum number of Shares being deposited;

(o)Shareholders who do not deposit their Shares under the Offer will realize an increase in their Share ownership in the Company to the extent that Shares are purchased by the Company pursuant to the Offer; and

(p)the Offer provides for equal and hence fair treatment of all Shareholders.

In connection with the Board of Directors approval at the October 26, 2023 meeting, certain directors of the Company, in accordance with subsection 120(1) of the Canada Business Corporations Act, notified the Company that they may have an interest in the Offer as a result of their current or prior involvement or relationship with the Principal Shareholder, namely Bradley W. Corson and Matthew R. Crocker. Accordingly, such directors abstained from voting on matters relating to the Offer at such meetings.

The foregoing summary of the factors considered by the Special Committee and the Board of Directors is not, and is not intended to be, exhaustive. In view of the variety of factors and the amount of information considered in connection with its determination to proceed with the Offer, the Special Committee and the Board of Directors did not find it practical to, and did not, quantify or otherwise attempt to assign any relative weight to each specific factor considered in reaching its conclusion.

None of Imperial, its Special Committee or its Board of Directors, the Dealer Manager or the Depositary makes any recommendation to any Shareholder as to whether to deposit or refrain from depositing Shares under the Offer. Shareholders are urged to evaluate carefully all information in the Offer, consult their own financial, legal, investment and tax advisors and make their own decisions whether to deposit Shares under the Offer, how many Shares to deposit and whether to specify a price and, if so, at what price to deposit such Shares. See Section 13 of the Circular, “Income Tax Considerations”.

Liquidity of Market

As at October 30, 2023, there were 554,945,083 Shares issued and outstanding, of which 168,703,705 Shares comprise the Public float, which excludes Shares beneficially owned, or over which control or direction is exercised, by “related parties” of the Company (which includes our directors and senior officers and any of our subsidiaries as well as any Person that beneficially owns or exercises control or direction, directly or indirectly, over 10% or more of the issued and outstanding Shares) and Shares that are not “freely tradeable” (each as defined in MI 61-101) (the “Public float”). The maximum number of Shares that the Company is offering to purchase pursuant to the Offer, if the Purchase Price is determined to be $78.50 (being the minimum price per Share under the Offer), represents approximately 3.4% of the Shares outstanding as of October 30, 2023. If the Company purchases such maximum number of Shares, there will be approximately 535,836,803 Shares outstanding following completion of the Offer.

If the Company purchases such maximum number of Shares and none of the related parties deposit their Shares pursuant to the Offer, the Public float will comprise approximately 149,595,425 Shares. Assuming the Offer is fully subscribed, the minimum number of Shares that we are offering to purchase pursuant to the Offer represents approximately 2.9% of the Shares issued and outstanding as of October 30, 2023. If the Company purchases the minimum of 15,957,446 Shares pursuant to the Offer, and none of our related parties deposit their Shares pursuant to the Offer, the Public float will comprise approximately 152,746,259 Shares.

Imperial is relying on the “liquid market exemption” specified in MI 61-101 from the requirement to obtain a formal valuation applicable to the Offer. Accordingly, the valuation requirements of securities regulatory authorities in Canada applicable to issuer bids generally are not applicable in connection with the Offer.

Imperial has determined that there is a liquid market in the Shares because:

(a)there is a published market for the Shares (the TSX and NYSE American);

(b)during the 12 months before October 26, 2023 (the last full trading day prior to the date the Offer was publicly announced):

(i)the number of issued and outstanding Shares was at all times at least 5,000,000 (excluding Shares beneficially owned, or over which control and direction was exercised, by related parties and securities that were not freely tradeable);

(ii)the aggregate trading volume of Shares on the TSX (the exchange on which the Shares were principally traded) was at least 1,000,000 Shares;

(iii)there were at least 1,000 trades in the Shares on the TSX; and

(iv)the aggregate value of the trades in the Shares on the TSX was at least $15,000,000;

(c)the market value of the Shares on the TSX, as determined in accordance with MI 61-101, was at least $75,000,000 for September 2023 (the calendar month preceding the calendar month in which the Offer was announced).

Imperial has also obtained, on a voluntary basis, the Liquidity Opinion of RBC Capital Markets to the effect that a liquid market for the Shares existed as of October 30, 2023 and that it is reasonable to conclude that, following the completion of the Offer, there will be a market for holders of Shares who do not tender to the Offer that is not materially less liquid than the market that existed at the time of the making of the Offer. A copy of the Liquidity Opinion of RBC Capital Markets is attached hereto as Schedule A and Shareholders are encouraged to read it in its entirety. The Liquidity Opinion is not a recommendation to any Shareholder as to whether to deposit or refrain from depositing Shares.

Based on the liquid market test set out above and the Liquidity Opinion of RBC Capital Markets, the Company determined that it is reasonable to conclude that, following the completion of the Offer, there will be a market for holders of Shares who do not tender to the Offer that is not materially less liquid than the market that existed at the time of the making of the Offer.

Accordingly, the valuation requirements of securities regulatory authorities in Canada applicable to issuer bids generally are not applicable in connection with the Offer.

For further information, see the tables and information included in Section 4 of the Circular, ‘‘Price Range of Shares’’, Section 5 of the Circular, ‘‘Dividend Policy’’, and Section 6 of the Circular, ‘‘Previous Purchases of Shares”.

Additional Securities Law Considerations

Imperial is a reporting issuer (or the equivalent thereof) in each of the provinces and territories of Canada, and the Shares are listed on the TSX. Imperial believes that the purchase of Shares pursuant to the Offer will not result in: (i) Imperial ceasing to be a reporting issuer in any jurisdiction in Canada, or (ii) the Shares being delisted from the TSX.

Imperial is a reporting issuer under the Exchange Act and the Shares are registered under Section 12(g) of the Exchange Act and have unlisted trading privileges on the NYSE American. Imperial believes that the purchase of Shares pursuant to the Offer will not result in: (i) the Shares becoming eligible for deregistration under Section 12(g) of the Exchange Act or (ii) the Shares losing their unlisted trading privileges on the NYSE American. The Offer is conditioned upon, among other things, the Company having determined that the consummation of the Offer is not reasonably likely to cause the Shares to lose their unlisted trading privileges on the NYSE American or to be eligible for deregistration under the Exchange Act.

The Shares are currently “margin securities” under the rules of the U.S. Federal Reserve Board. This has the effect, among other things, of allowing brokers to extend credit on the collateral of the Shares. The Company believes that, following the repurchase of Shares pursuant to the Offer, the Shares will continue to be margin securities for the purposes of the U.S. Federal Reserve Board’s margin regulations.

Disposition of shares pursuant to Imperial Oil Limited normal course issuer bid to maintain proportionate ownership

10.ARRANGEMENTS CONCERNING SHARES

Acceptance of the Offer

The Principal Shareholder has advised the Company that it will make a Proportionate Tender in order to maintain its proportionate Share ownership in the Company following completion of the Offer. In making a Proportionate Tender, ExxonMobil allows other Shareholders to determine the Purchase Price and the aggregate number of Shares tendered in the Offer, thus eliminating any effect ExxonMobil could have on other Shareholders by making an Auction Tender or a Purchase Price Tender. ExxonMobil will receive the same consideration for its Shares on a per Share basis as all other Shareholders.

To the knowledge of the Company, after reasonable inquiry, none of the people named under Section 9 of the Circular “Interest of Directors and Officers – Ownership of Imperial’s Securities”, other than ExxonMobil, will be depositing any Shares pursuant to the Offer.

The intention of the Principal Shareholder, the directors and officers of the Company and their respective associates or affiliates as described above may change or, subject to compliance with applicable laws, Shares may be sold on the TSX or NYSE American during the period of the Offer depending on the change in circumstance of such parties.

Commitments to Acquire Shares

Imperial has no agreements, commitments or understandings to purchase Shares other than pursuant to the Offer and other than pursuant to the Savings Plan. To the knowledge of the Company, after reasonable inquiry, no Person or company referred to in this Circular under Section 9 of the Circular “Interest of Directors and Officers – Ownership of Imperial’s Securities” has any agreement, commitment or understanding to acquire securities of the Company.

Benefits from the Offer

Except as described or referred to in the Offer, no Person or company named under Section 9 of the Circular “Interest of Directors and Officers – Ownership of Imperial’s Securities” will receive any direct or indirect benefit from accepting or refusing to accept the Offer other than the Purchase Price for any Shares purchased by the Company in accordance with the terms of the Offer and any benefit available to any Shareholder who does or does not participate in the Offer. See Section 3 of the Circular, “Purpose and Effect of the Offer”.

Contracts, Arrangements or Understandings with Shareholders

Except as described or referred to in the Offer, there are no contracts, arrangements or understandings, formal or informal, made or proposed to be made between the Company and any holder of any securities of the Company in relation to the Offer.

11.MATERIAL CHANGES IN THE AFFAIRS OF THE COMPANY

Except as described or referred to in the Offer or as otherwise publicly disclosed, the Company is not aware of any plans or proposals for material changes in the affairs of the Company, or of any undisclosed material changes, that have occurred since November 1, 2023, the date on which the Company’s most recent interim financial report was filed by the Company with the Canadian securities regulatory authorities, which may be accessed on SEDAR+’s website at www.sedarplus.ca and on EDGAR’s website at www.sec.gov.

The Company considers strategic acquisition and divestment opportunities on an ongoing basis. The Company may have proposals, letters of intent, exclusivity arrangements or other conditional commitments outstanding with respect to opportunities which may, if they proceed, be material to the Company. However, there can be no assurance that any of these discussions will result in a definitive agreement and, if they do, what the terms or timing of any acquisition, investment or disposition would be or that such acquisition, investment or disposition will be completed by the Company.

12.PRIOR VALUATIONS AND BONA FIDE OFFERS

The Company is relying on the “liquid market exemption” specified in MI 61-101. Accordingly, the valuation requirements of securities regulatory authorities in Canada applicable to issuer bids generally are not applicable in connection with the Offer.

To the knowledge of the directors and officers of the Company, after reasonable inquiry, no “prior valuation” (as defined in MI 61-101) in respect of the Company has been made in the 24 months before the date hereof. No bona fide prior offer that relates to the Shares or is otherwise relevant to the Offer has been received by the Company during the 24 months preceding the date of the Offer.

13.INCOME TAX CONSIDERATIONS

Certain Canadian Federal Income Tax Considerations

The Company has been advised by Stikeman Elliott LLP that the following summary describes certain of the principal Canadian federal income tax considerations pursuant to the Tax Act generally applicable, as at the date hereof, to a disposition of Shares pursuant to the Offer.

This summary is based on the current provisions of the Tax Act, the regulations thereunder, the Proposed Amendments and counsel’s understanding of the current administrative policies and assessing practices of the CRA published in writing prior to the date hereof. This summary assumes that the Proposed Amendments will be enacted in the form currently proposed. No assurances can be given that the Proposed Amendments will be enacted as currently proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policies or assessing practices, whether by judicial, governmental or legislative decision or action, nor does it take into account provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein.

This summary is not applicable to a Shareholder: (i) that is a “financial institution”, (ii) that is a “specified financial institution” or a “restricted financial institution”, (iii) an interest in which is a “tax shelter investment”, (iv) that reports its “Canadian tax results” in a currency other than Canadian dollars, (v) that is a partnership or a trust, or (vi) that has entered into a “derivative forward agreement” or a “dividend rental arrangement” in respect of the Shares, as each of those terms is defined in the Tax Act. This summary is also not applicable to a Shareholder that acquired Shares pursuant to the exercise of an employee stock option and who disposes of such Shares pursuant to the Offer. Such Shareholders should consult their own tax advisors regarding their particular circumstances.

This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations. This summary is not, and should not be construed as, legal or tax advice to any particular Shareholder and no representations with respect to Canadian federal income tax consequences to any particular Shareholder are made. Accordingly, Shareholders are urged to consult their own tax advisors with respect to their particular circumstances.

Having regard to the deemed dividend tax treatment (including Canadian withholding tax for non- residents of Canada) described below on a disposition of Shares pursuant to the Offer as opposed to capital gains (or capital loss) treatment which would generally apply to a disposition in the market, Shareholders who wish to dispose of their Shares and who are not generally exempt from Canadian federal income tax should consult their tax advisors regarding the disposition of their Shares in the market as an alternative to disposing of their Shares pursuant to the Offer, in order that capital gains (or capital loss) treatment apply on the disposition of their Shares.

For purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition or deemed disposition of Shares must be expressed in Canadian dollars. This summary assumes that at all relevant times the Shares are listed on a “designated stock exchange” as defined in the Tax Act (which currently includes the TSX).

Residents of Canada

This portion of the summary is applicable to a Resident Shareholder. Generally, Shares will be considered to be capital property to a Resident Shareholder provided that the Resident Shareholder does not hold the Shares in the course of carrying on a business and has not acquired the Shares in one or more transactions considered to be an adventure or concern in the nature of trade. A Resident Shareholder whose Shares might not otherwise qualify as capital property may, in certain circumstances, make an irrevocable election under subsection 39(4) of the Tax Act to have the Shares and every other “Canadian security”, as defined in the Tax Act, owned by such Resident Shareholder in the taxation year of the election and in all subsequent taxation years deemed to be capital property. Resident Shareholders are advised to consult their own tax advisors to determine if this election is appropriate in their particular circumstances.

A Resident Shareholder who disposes of Shares pursuant to the Offer will be deemed to receive a taxable dividend on a separate class of shares comprising the Shares so sold equal to the excess of the amount paid by Imperial for the Shares, being the Purchase Price, over their paid-up capital for purposes of the Tax Act. Imperial estimates that on the Expiration Date the paid-up capital per Share should not exceed $1.75 for purposes of the Tax Act. As a result, Imperial expects that a Resident Shareholder who disposes of Shares under the Offer will be deemed to receive a taxable dividend. The exact quantum of the deemed dividend cannot be guaranteed.

Any dividend deemed to be received by a Resident Shareholder who is an individual will be subject to gross- up and dividend tax credit rules applicable to taxable dividends received by Canadian resident individuals from a taxable Canadian corporation, including the enhanced gross-up and dividend tax credit with respect to eligible dividends, if applicable. There may be limitations on the ability of a corporation to designate dividends as eligible dividends. Imperial intends to designate the maximum amount, as permitted without creating taxes for Imperial under the Tax Act, of the deemed dividend as an eligible dividend.

Subject to the application of subsection 55(2) of the Tax Act, as described below, any dividend deemed to be received by a Resident Shareholder that is a corporation will be included in computing such Resident Shareholder’s income as a dividend, and will ordinarily be deductible in computing its taxable income subject also to all other limitations under the Tax Act. To the extent that such a deduction is available, private corporations (as defined in the Tax Act) and certain other corporations may be liable to pay tax under Part IV of the Tax Act at a rate of 38 1/3% of the amount of the deemed dividend. This additional tax may be refundable in certain circumstances.

Under subsection 55(2) of the Tax Act, a Resident Shareholder that is a corporation may be required to treat all or a portion of any deemed dividend that is deductible in computing taxable income as proceeds of disposition of capital property and not as a dividend where the Resident Shareholder would have realized a capital gain if it disposed of any Share at fair market value immediately before the disposition of Shares to Imperial, the disposition to Imperial resulted in a significant reduction in such capital gain and the dividend exceeds the “safe income” in respect of the particular Share that could reasonably be considered to contribute to such capital gain. Subsection 55(2) of the Tax Act does not apply to the portion of the taxable dividend subject to tax under Part IV of the Tax Act that is not refunded under the circumstances specified in subsection 55(2) of the Tax Act. The application of subsection 55(2) of the Tax Act involves a number of factual considerations that will differ for each Resident Shareholder and a Resident Shareholder to whom it may be relevant is urged to consult its own tax advisors concerning its application having regard to its particular circumstances.

The amount paid by Imperial under the Offer for the Shares less any amount deemed to be received by the Resident Shareholder as a dividend (after the application of subsection 55(2) of the Tax Act, if applicable, in the case of a corporate Resident Shareholder) will be treated as proceeds of disposition of the Shares. The Resident Shareholder will realize a capital gain (or capital loss) on the disposition of the Shares equal to the amount by which the Resident Shareholder’s proceeds of disposition, net of any costs of disposition, exceed (or are less than) the adjusted cost base to the Resident Shareholder of the Shares sold to Imperial pursuant to the Offer.

Generally, a Resident Shareholder will be required to include in computing its income for a taxation year one-half of any capital gain (a “Taxable capital gain”) realized by it in that year. A Resident Shareholder must generally deduct one-half of the amount of any capital loss (an “Allowable capital loss”) realized in a taxation year from Taxable capital gains realized by the Resident Shareholder in that year, and any excess may generally be applied to reduce Taxable capital gains realized by the Resident Shareholder in the three preceding taxation years or in any subsequent taxation year to the extent and under the circumstances specified in the Tax Act.

The amount of a capital loss realized on the disposition of a Share by a Resident Shareholder that is a corporation should, to the extent and under the circumstances specified in the Tax Act, be reduced by the amount of dividends received or deemed to be received on the Shares (including any dividends deemed to be received as a result of the disposition of Shares to Imperial under the Offer). Similar rules may apply where Shares are owned by a partnership or trust of which a corporation, trust or partnership is a member or beneficiary. Resident Shareholders who may be affected by these rules are urged to consult with their own tax advisors in this regard.

A Resident Shareholder who is an individual (other than a trust) and has realized a capital loss on the disposition of Shares pursuant to the Offer could have all or a portion of that loss denied under the “superficial loss” rules set out in the Tax Act. In general, these rules apply where such Resident Shareholder or a Person affiliated with such Resident Shareholder has acquired Shares in the period beginning 30 days before the disposition of Shares pursuant to the Offer and ending 30 days after the disposition of Shares pursuant to the Offer, and such acquired Shares are owned by such Resident Shareholder or by a Person affiliated with such Resident Shareholder at the end of such period. Resident Shareholders are urged to consult their own tax advisors with respect to the “superficial loss” rules.

A Resident Shareholder that is a corporation or trust and has realized a capital loss on the disposition of Shares pursuant to the Offer could have all or a portion of that loss denied under the “stop-loss” rules set out in the Tax Act. In general, these rules apply where such Resident Shareholder or a Person affiliated with such Resident Shareholder has acquired Shares in the period beginning 30 days before the disposition of Shares pursuant to the Offer and ending 30 days after the disposition of Shares pursuant to the Offer, and such acquired Shares are owned by such Resident Shareholder or by a Person affiliated with such Resident Shareholder at the end of such period. Resident Shareholders are urged to consult their own tax advisors with respect to the “stop-loss” rules.

A Resident Shareholder that is a “Canadian-controlled private corporation” (as defined in the Tax Act) throughout the year may be liable to pay an additional tax on its “aggregate investment income” for the year, which is defined to include an amount in respect of Taxable capital gains. This additional tax may be refundable in certain circumstances. Proposed Amendments released by the Minister of Finance (Canada) on August 9, 2022, are intended to extend this additional tax and refund mechanism in respect of aggregate investment income to “substantive CCPCs” (as proposed to be defined in the Tax Act). Resident Shareholders are advised to consult their own tax advisors regarding the possible implications of these Proposed Amendments in their particular circumstances.

A Resident Shareholder who is an individual or a trust (other than certain specified trusts), who realizes a capital gain or who is deemed to receive a dividend on the disposition of Shares pursuant to the Offer may be subject to alternative minimum tax under the Tax Act as calculated pursuant to the detailed rules contained therein. Such Resident Shareholders should consult their own tax advisors with respect to the alternative minimum tax rules set out in the Tax Act.

Non-Residents of Canada

This portion of the summary is applicable to a Non-Resident Shareholder.

A Non-Resident Shareholder who disposes of Shares pursuant to the Offer will be deemed to receive a dividend equal to the excess of the amount paid by Imperial for the Shares, being the Purchase Price, over their paid- up capital for Canadian income tax purposes. As a result, Imperial expects that Non-Resident Shareholders who disposes of Shares under the Offer will be deemed to receive a dividend. Imperial estimates that on the Expiration Date the paid-up capital per Share should not exceed $1.75 for purposes of the Tax Act. The exact quantum of the deemed dividend cannot be guaranteed. Any such dividend will be subject to Canadian withholding tax at a rate of 25% or such lower rate as may be provided under the terms of an applicable Canadian tax treaty.

A Non-Resident Shareholder will not be subject to tax under the Tax Act in respect of any capital gain realized on the disposition of a Share pursuant to the Offer.

In view of the deemed dividend tax treatment described above on a sale of Shares pursuant to this Offer and the resulting Canadian withholding tax, Non-Resident Shareholders should consult their own tax advisors regarding selling their Shares in the market as an alternative to selling Shares pursuant to the Offer.

Certain United States Federal Income Tax Considerations

The following discussion describes certain material U.S. federal income tax consequences of the Offer to Shareholders whose securities are properly tendered and accepted for payment pursuant to the Offer. Those Shareholders who do not participate in the Offer will not incur any U.S. federal income tax liability as a result of the Offer.

This discussion is based upon the provisions of the Code, existing final and temporary regulations promulgated thereunder (the “Treasury Regulations”), and current administrative rulings and court decisions, all of which are subject to change, possibly with retroactive effect. Changes in these authorities may cause the U.S. federal income tax consequences to vary substantially from those described below.

This discussion applies only to U.S. Holders (as defined below) of the Company’s Shares that own the Shares as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment), and does not comment on all aspects of U.S. federal income taxation that may be important to certain Shareholders in light of their particular circumstances, such as Shareholders subject to special tax rules (e.g., banks and other financial institutions, brokers, dealers or traders in securities or commodities, insurance companies, regulated investment companies, real estate investment trusts, traders that elect to mark-to-market their securities, certain expatriates or former long-term residents of the United States, personal holding companies, “S” corporations, U.S. expatriates, tax- exempt organizations, tax-qualified retirement plans, Persons that own 10% or more of the Company’s voting stock, Persons who are subject to alternative minimum tax, Persons who hold Shares as a position in a “straddle” or as part of a “hedging,” “conversion” or “integrated” transaction, Persons that have a functional currency other than the U.S. dollar, controlled foreign corporations, passive foreign investment companies, or Persons who acquired Shares through the exercise of employee stock options or otherwise as compensation for services). If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) is a Shareholder, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships or partners in a partnership holding Shares should consult their own tax advisors regarding the tax consequences of participating in the Offer.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE OFFER. SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX LAWS) OF THE OFFER.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of Shares that is, for U.S. federal income tax purposes: (i) a U.S. citizen or U.S. resident alien, (ii) a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, that was created or organized under the laws of the United States, any State thereof or the District of Columbia, (iii) an estate whose income is subject to U.S. federal income taxation regardless of its source, or (iv) a trust that either is subject to the supervision of a court within the United States and has one or more U.S. Persons with authority to control all of its substantial decisions or has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. Person.

Characterization of the Purchase — Distribution vs. Sale Treatment

The purchase of Shares from a U.S. Holder pursuant to the Offer generally will be a taxable transaction for

U.S. federal income tax purposes. As a consequence of any such purchase, a U.S. Holder will, depending on the

U.S. Holder’s particular circumstances, be treated either as having sold its Shares or as having received a distribution in respect of such Shares. The purchase will be treated as a sale if a U.S. Holder meets at least one of the three tests discussed below (the “Section 302 tests”). The purchase will be treated as a distribution if the U.S. Holder does not satisfy any of the Section 302 tests.

Section 302 Tests — Determination of Sale or Distribution Treatment

The purchase of Shares pursuant to the Offer will be treated as a sale of the Shares by a U.S. Holder if any of the following Section 302 tests is satisfied:

•as a result of the purchase, there is a “complete redemption” of the U.S. Holder’s equity interest in the Company;

•as a result of the purchase, there is a “substantially disproportionate” reduction in the U.S. Holder’s equity interest in the Company; or

•the receipt of cash by the U.S. Holder is “not essentially equivalent to a dividend”. These tests are described more fully below.

For purposes of the Section 302 tests, the constructive ownership rules of Section 318 of the Code generally apply. As a result, a U.S. Holder is treated as owning not only stock of the Company actually owned by such holder but also stock of the Company actually (and in some cases constructively) owned by certain related entities and individuals. Under the constructive ownership rules, a U.S. Holder will be considered to own stock of the Company owned, directly or indirectly, by certain members of the holder’s family and certain entities (such as corporations, partnerships, trusts and estates) in which the U.S. Holder has an equity interest or (in the case of a U.S. Holder that is itself an entity) which have an interest in the U.S Holder, as well as certain stock of the Company which the U.S. Holder has an option to acquire or can acquire by exchange of a convertible security. U.S. Holders should consult their own tax advisors with respect to the operation of these constructive ownership rules.

The purchase of Shares pursuant to the Offer will result in a “complete redemption” of a U.S. Holder’s equity interest in the Company for purposes of the Section 302 tests, if, immediately after such purchase, such U.S. Holder owns, actually and constructively, no stock of the Company. In applying the “complete redemption” test, U.S. Holders may be able to waive the application of constructive ownership through the family attribution rules, provided that such

U.S. Holders comply with the provisions of Section 302(c)(2) of the Code and applicable U.S. Treasury Regulations.

U.S. Holders wishing to satisfy the “complete redemption” test through satisfaction of the special conditions set forth in Section 302(c)(2) of the Code should consult their tax advisors concerning the mechanics and desirability of those conditions.

In general, the purchase of a U.S. Holder’s Shares pursuant to the Offer will be “substantially disproportionate” as to a U.S. Holder for purposes of the Section 302 tests if, immediately after the purchase, the percentage of the outstanding voting stock of the Company that the U.S. Holder actually and constructively owns is less than 80% of the percentage of the outstanding voting stock of the Company actually and constructively owned by such U.S. Holder immediately before the purchase and, immediately following the exchange, such U.S. Holder actually and constructively owns less than 50% of the total combined voting power of the Company.

The purchase of a U.S. Holder’s Shares pursuant to the Offer will be treated as “not essentially equivalent to a dividend” for purposes of the Section 302 tests if it results in a “meaningful reduction” in the U.S. Holder’s proportionate interest in the Company, given the U.S. Holder’s particular facts and circumstances. The IRS has indicated in a published ruling that even a small reduction in the percentage interest of a Shareholder whose relative stock interest in a publicly held corporation is minimal after taking into account the constructive ownership rules of Section 318 of the Code, and who exercises no control over corporate affairs should constitute a “meaningful reduction”. U.S. Holders who intend to qualify for sale treatment by demonstrating that the proceeds received from the Company are “not essentially equivalent to a dividend” should consult their tax advisors to determine the possibility of satisfying this test.

The Company cannot predict whether any particular U.S. Holder will be subject to sale or distribution treatment.

Each U.S. Holder should be aware that because proration may occur in the Offer, even if all of the Shares actually and constructively owned by a U.S. Holder are tendered pursuant to the Offer and the U.S. Holder does not actually or constructively own any other stock of the Company, fewer than all of such Shares may be purchased by the Company. Also, a tendering U.S. Holder may not be able to satisfy one of the Section 302 Tests because of contemporaneous acquisitions of shares by such U.S. Holder or a related party whose shares are attributed to such

U.S. Holder. Consequently, the Company cannot provide assurances that a sufficient number of any particular U.S. Holder’s Shares will be purchased to ensure that this purchase will be treated as a sale, rather than as a distribution, for U.S. federal income tax purposes.

Treatment of a Sale of Shares

Subject to the PFIC rules discussed below, a U.S. Holder that satisfies any of the Section 302 tests described above will be treated as having sold the Shares purchased by the Company pursuant to the Offer and generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash received under the Offer and the U.S. Holder’s adjusted tax basis in such Shares. The gain or loss recognized generally will be treated as (i) long-term capital gain or loss if the U.S. Holder’s holding period is greater than one year as of the date of the Company’s purchase pursuant to the Offer and (ii) U.S. source income or loss, as applicable, for foreign tax credit purposes. However, if a U.S. Holder is eligible for the benefits of the tax treaty between the United States and Canada, the U.S. Holder may be entitled to elect to treat the portion of any such gain that is subject to Canadian tax as foreign source income for foreign tax credit purposes. If a U.S. Holder is not able to make such election, it will generally not be able to credit any Canadian tax imposed on the sale of Shares unless such credit can be applied (subject to applicable limitations) against tax due on other foreign source income. In addition, under recently finalized Treasury Regulations, a U.S. Holder will generally be precluded from claiming a foreign tax credit in respect of any

such taxes unless the U.S. Holder is eligible for and elects to apply the benefits of the tax treaty between the United States and Canada.

Certain U.S. Holders, including individuals, may be eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations (including the “wash sale” rules under the Code). A U.S. Holder must calculate gain or loss separately for each block of Shares (generally, Shares acquired at the same cost in a single transaction). A U.S. Holder may be able to designate which blocks of Shares it wishes to tender and the order in which different blocks will be purchased in the event that less than all of its Shares are tendered. U.S. Holders should consult their tax advisors concerning the mechanics and desirability of that designation.

Treatment of a Distribution in Respect of Shares.

Subject to the PFIC rules discussed below, if a U.S. Holder does not satisfy any of the Section 302 tests described above, the full amount received by the U.S. Holder pursuant to the Offer will be treated as a distribution to the U.S. Holder with respect to the U.S. Holder’s Shares. The tax basis of the Shares that a U.S. Holder sells pursuant to the Offer will be added to the tax basis of such holder’s remaining Shares. To the extent of the Company’s current and accumulated earnings and profits allocated to the U.S. Holder’s Shares, as determined under U.S. federal income tax principles, this distribution generally will be treated as a dividend. Such a dividend would be includible in the U.S. Holder’s gross income as ordinary income without reduction for the tax basis of the Shares exchanged, and no current loss would be recognized.

Non-corporate U.S. Holders generally will be subject to U.S. federal income tax at a maximum rate of 20% with respect to any such dividend income, provided that (1) the shares are readily tradable on an established securities market in the United States or the Company is eligible for benefits under a comprehensive United States income tax treaty which the IRS has approved for these purposes, (2) the Company is not a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year, (3) such U.S. Holder satisfies a holding period requirement and (4) such U.S. Holder is not under an obligation (whether pursuant to a short sale or otherwise) to make payments with respect to positions in substantially similar or related property. The Company believes that the shares are readily tradable on an established securities market in the United States.

Amounts treated as a dividend will be treated as foreign source income for U.S. federal income tax purposes. Subject to various limitations, a U.S. Holder may elect to claim a foreign tax credit against its United States federal income tax liability for Canadian income tax paid with respect to any such dividend income. However, under recently finalized Treasury Regulations, it is possible that such taxes may not be creditable unless a U.S. Holder is eligible for and elects to apply the benefits of the tax treaty between the United States and Canada. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the preferential tax rates. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, any amount treated as a dividend will generally be categorized as “passive category income” for United States foreign tax credit purposes. U.S. Holders who do not elect to claim the foreign tax credit may instead claim a deduction for Canadian income tax paid, but only for a year in which the U.S. Holder elects to do so with respect to all foreign income taxes. A deduction does not reduce the United States tax on a dollar-for-dollar basis like a tax credit. The deduction, however, is not subject to the same limitations applicable to foreign tax credits. The rules relating to the foreign tax credit determination are complex. Accordingly, U.S. Holders should consult their own tax advisors to determine whether and to what extent they may be entitled to the credit.

Distributions in excess of the Company’s current and accumulated earnings and profits allocated to the U.S. Holder’s Shares will be treated first as a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in its Shares and thereafter as capital gain, which will be either long-term or short-term capital gain depending upon whether the U.S. Holder has held the Shares for more than one year. See, however, the discussion of the PFIC rules below, which could materially alter this treatment.

The Company does not maintain and will not report calculations of its earnings and profits in accordance with U.S. federal income tax accounting principles. U.S. Holders should consult their tax advisors as to whether all or any part of the payment received from the Company should be treated as a dividend.

Medicare Surtax

U.S. Holders who are individuals, estates or trusts and whose income exceeds certain thresholds will also be required to pay (in addition to U.S. federal income tax) a 3.8% Medicare surtax on net investment income, including dividends and gains from the sale or other taxable disposition of the Shares. U.S. Holders are urged to consult their tax advisers regarding whether the Medicare surtax will apply to them.

Reporting Requirement for Significant Holders

A U.S. Holder that is considered a “significant holder” within the meaning of U.S. Treasury Regulation Section 1.302-2(b) who exchanges Shares for cash pursuant to the Offer may be required to comply with the reporting requirements of such regulation.

Passive Foreign Investment Company

Generally, a PFIC is a non-U.S. corporation that, in any tax year, receives passive income in an amount equal to 75% or more of its gross income or holds assets for the production of passive income representing 50% or more of the average quarterly value of its assets determined, broadly speaking, on a consolidated basis with its subsidiaries. A company’s status as a PFIC must be determined every year based on the income, assets and operations of the company for that year. Because this is a factual determination that must be made annually, no assurance can be provided that the Company will not be a PFIC in the current taxable year or that it was never a PFIC in a prior taxable year. However, based on its current and projected assets and income, the Company expects that it will not be a PFIC for its current taxable year, although there is no assurance that this will in fact be the case.

If the Company is treated as a PFIC in any year in which a U.S. Holder has held its Shares, certain adverse consequences could apply to payments made with respect to the Offer, including (1) that gain on the disposition of Shares could be treated as ordinary income and subject to additional tax in the nature of interest, (2) amounts treated as distributions on the Shares may fail to qualify for the preferential rates of taxation and (3) additional reporting requirements may apply to U.S. Holders. U.S. Holders should consult with their tax advisors as to the effect of these rules on their tender of Shares pursuant to the Offer.

Backup Withholding and Information Reporting

The sale by a U.S. Holder of Shares pursuant to the Offer may be subject to information reporting requirements. Additionally, backup withholding may apply to the purchase price for Shares paid pursuant to the Offer to a non-corporate U.S. holder that fails to provide an accurate taxpayer identification number, is notified by the IRS that the holder has failed to report all interest and dividends required to be shown on the holder’s federal income tax returns, or, in certain circumstances, fails to comply with applicable certification requirements. A U.S. Holder generally may obtain a refund of amounts withheld under the backup withholding rules that exceed the U.S. Holder’s income tax liability by filing a refund claim with the IRS.

THIS DISCUSSION IS GENERAL IN NATURE AND DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A PARTICULAR SHAREHOLDER IN LIGHT OF THE SHAREHOLDER’S PARTICULAR CIRCUMSTANCES, OR TO CERTAIN TYPES OF SHAREHOLDERS SUBJECT TO SPECIAL TREATMENT UNDER U.S. FEDERAL INCOME TAX LAWS. YOU ARE ADVISED TO CONSULT WITH YOUR OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE OFFER, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS.

14.LEGAL MATTERS AND REGULATORY APPROVALS

Imperial is not aware of any license or regulatory permit that is material to the Company’s business that might be adversely affected by the Company’s acquisition of Shares pursuant to the Offer or, except as noted below, of any approval or other action by any government or governmental, administrative or regulatory authority or agency in any jurisdiction, that would be required for the acquisition of Shares by the Company pursuant to the Offer and that has not been obtained on or before the date hereof. Should any such approval or other action be required, the Company currently contemplates that such approval will be sought or other action will be taken. Imperial cannot predict whether it may determine that it must delay the acceptance for payment of Shares deposited pursuant to the Offer pending the outcome of any such matter.

There can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that the failure to obtain any such approval or other action might not result in adverse consequences to the Company’s business.

In order to facilitate the availability of Proportionate Tenders pursuant to the Offer and to permit the Company to extend the Offer without first taking up validly deposited Shares in certain circumstances, the Company has applied for the Securities Regulatory Relief. Accordingly, if the Securities Regulatory Relief is granted, in the event that Imperial elects to extend the Offer, Imperial will not take up or pay for any Shares until the expiry of such extension.

15.SOURCE OF FUNDS

The Company expects to fund the purchase of Shares pursuant to the Offer, including all related fees and expenses, with available cash on hand.

16.DEALER MANAGER

RBC Capital Markets has been retained to serve as Dealer Manager in connection with the Offer. The Dealer Manager may communicate with investment dealers, stock brokers, commercial banks, trust companies and dealers with respect to the Offer. RBC Capital Markets has also been retained as financial advisor in connection with the Offer and to provide a liquidity opinion.

The Dealer Manager and its affiliates has provided, and may in the future provide, various investment banking, commercial banking and other services to us for which it has received, or we expect it will receive, customary compensation from us.

In the ordinary course of business, including in its trading and brokerage operations and in a fiduciary capacity, the Dealer Manager and its affiliates may hold positions, both long and short, for their own accounts and for those of their customers, in our securities. The Dealer Manager may from time to time hold Shares in its proprietary accounts, and, to the extent it owns Shares in these accounts at the time of the Offer, the Dealer Managers may tender the Shares pursuant to the Offer.

17.DEPOSITARY

Imperial has appointed Computershare Investor Services Inc. to act as a depositary for, among other things,

(a) the receipt of certificates and/or DRIP positions representing Shares and related Letters of Transmittal deposited under the Offer, (b) the receipt of Notices of Guaranteed Delivery delivered pursuant to the procedures for guaranteed delivery set forth in Section 5 of the Offer to Purchase, “Procedure for Depositing Shares”, (c) the receipt from the Company of cash to be paid in consideration of the Shares acquired by the Company under the Offer, as agent for the depositing Shareholders, and (d) the transmittal of such cash to the depositing Shareholders, as agent for the depositing Shareholders, including the conversion of such cash from Canadian dollars to United States dollars for depositing Shareholders who elect to receive payment of the Purchase Price for their Shares in United States dollars. The Depositary may contact Shareholders by mail, telephone or facsimile and may request brokers, dealers and other nominee Shareholders to forward materials relating to the Offer to beneficial owners. The Depositary is not an affiliate of the Company.

18.FEES AND EXPENSES

RBC Capital Markets has been retained by the Company to serve as Dealer Manager and financial advisor in connection with the Offer and to deliver a liquidity opinion in connection with the Offer to the Board of Directors for which it will receive a fee from Imperial for its services. Imperial has agreed to reimburse RBC Capital Markets for certain reasonable out-of-pocket expenses incurred in connection with the Offer and to indemnify RBC Capital Markets against certain liabilities to which it may become subject as a result of its engagement. None of the fees payable to RBC Capital Markets are contingent upon the conclusions reached by RBC Capital Markets in the Liquidity Opinion.

Imperial has retained Computershare Investor Services Inc. to act as the Depositary in connection with the Offer. The Depositary will receive reasonable and customary compensation for its services, will be reimbursed for certain reasonable out-of-pocket expenses and will be indemnified against certain liabilities and expenses in connection with the Offer, including certain liabilities under Canadian provincial and territorial securities laws.

Imperial will not pay any fees or commissions to any broker or dealer or any other Person for soliciting deposits of Shares pursuant to the Offer. Brokers, dealers, commercial banks and trust companies will, upon request, be reimbursed by the Company for reasonable and necessary costs and expenses incurred by them in forwarding materials to their customers.

Imperial is expected to incur expenses of approximately $2 million in connection with the Offer, which includes filing fees, advisory fees, the fees of RBC Capital Markets, the Transfer Agent, the Depositary, legal, translation, accounting and printing fees.

19.CANADIAN STATUTORY RIGHTS

Securities legislation in the provinces and territories of Canada provides Shareholders with, in addition to any other rights they may have at law, one or more rights of rescission, price revision or to damages, if there is a misrepresentation in a circular or notice that is required to be delivered to the Shareholders. However, such rights must be exercised within prescribed time limits. Shareholders should refer to the applicable provisions of the securities legislation of their province or territory for particulars of those rights or consult a lawyer.

Imperial Oil Limited

505 Quarry Park Boulevard S.E.

Calgary, Alberta

Canada, T2C 5N1

To the Special Committee and the Board:

RBC Dominion Securities Inc. (“RBC”, “we” or “us”), a member company of RBC Capital Markets, understands that Imperial Oil Limited (the “Company”) is proposing to make a substantial issuer bid (the “Substantial Issuer Bid”) to acquire up to $1,500,000,000 in value of the common shares (the “Shares”) of the Company by way of a combination of a modified Dutch Auction and a proportionate tender at a price not less than $78.50 per Share and not more than $94.00 per Share. Exxon Mobil Corporation ("ExxonMobil") is the beneficial owner of 386,241,378 Shares, which represent approximately 69.6% of all issued and outstanding Shares. RBC understands that ExxonMobil has advised the Company that it intends to make a proportionate tender that will result in ExxonMobil maintaining its proportionate equity ownership in the Company following the completion of the Substantial Issuer Bid. RBC also understands that the terms and conditions of the Substantial Issuer Bid will be set forth in an offer to purchase and issuer bid circular to be mailed to the holders of the Shares in connection with the Substantial Issuer Bid (the “Offer to Purchase”). The terms used herein which are used or defined in the Offer to Purchase and not otherwise defined herein will have the same meaning as used in the Offer to Purchase.

RBC understands that a special committee (the “Special Committee”) of the Board of Directors (the “Board”) of the Company has been constituted to consider the Substantial Issuer Bid and make recommendations thereon to the Board. The Company has retained RBC to provide advice and assistance to the Special Committee and the Board in evaluating the Substantial Issuer Bid, including the preparation and delivery to the Special Committee and the Board of RBC’s opinion (the “Opinion”) as to whether, as of the date hereof, (i) a liquid market for the Shares exists, and (ii) it is reasonable to conclude that, following the completion of the Substantial Issuer Bid, there will be a market for holders of the Shares who do not tender to the Substantial Issuer Bid that is not materially less liquid than the market that existed at the time of the making of the Substantial Issuer Bid. The Special Committee and the Board have, on a voluntary basis, obtained the Opinion from RBC notwithstanding that such opinion is not required pursuant to Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions (“MI 61-101”). In addition, RBC has been retained by the Company to act as dealer manager (“Dealer Manager”) in connection with the Substantial Issuer Bid.

Engagement

RBC was formally engaged by the Company through an agreement between the Company and RBC (the “Engagement Agreement”) dated as of September 26, 2023 and amended as of October 13, 2023. The terms of the Engagement Agreement provide that RBC is to be paid a fee for its services as financial advisor and Dealer Manager, including fees that are contingent on the outcome of the Substantial Issuer Bid. In addition, RBC is to be reimbursed for its reasonable out-of-pocket expenses and to be indemnified by the Company in certain circumstances. RBC consents to the inclusion of the Opinion in its entirety and a summary thereof in the Offer to Purchase and to the filing thereof, as necessary, by the Company with the securities commissions or similar regulatory authorities in each province of Canada and in the United States.

RBC acts as a trader and dealer, both as principal and agent, in major financial markets and, as such, may have had and may in the future have positions in the Shares or other securities of the Company, or any of its associates or affiliates and, from time to time, may have executed or may execute transactions on behalf of such companies or clients for which it received or may receive compensation. As an investment dealer, RBC conducts research on securities and may, in the ordinary course of its business, provide research reports and investment advice to its clients on investment matters, including with respect to the Company, the Shares or the Substantial Issuer Bid.

Credentials of RBC Capital Markets

RBC Capital Markets also has significant operations in the United States and internationally. The Opinion expressed herein represents the opinion of RBC and the form and content herein have been approved for release by a committee of its managing directors, each of whom is experienced in merger, acquisition, divestiture and opinion matters.

Scope of Review

In connection with our Opinion, we have reviewed and relied upon or carried out, among other things, the following:

1.the most recent draft of the Offer to Purchase (the “Draft Offer to Purchase”), dated October 30, 2023;

2.the trading activity, volumes, and price history of the Shares on the Toronto Stock Exchange and other alternative trading venues;

4.the number of Shares proposed to be purchased under the Substantial Issuer Bid relative to the total number of Shares issued and outstanding;

5.public information with respect to the Company and the Shares;

6.the definition of “liquid market” as outlined in MI 61-101 and certain other parameters in MI 61-101;

8.discussions with senior management and legal counsel of the Company; and

9.such other corporate, industry, and financial market information, investigations and analyses as RBC considered necessary or appropriate in the circumstances.

RBC CAPITAL MARKETS

Assumptions and Limitations

With the Board’s approval and as provided for in the Engagement Agreement, RBC has relied upon the completeness, accuracy, and fair representation of all of the financial and other information, data, advice, opinions, or representations obtained by it from public sources, senior management of the Company, and their consultants and advisors (collectively, the “Information”). The Opinion is conditional upon such completeness, accuracy, and fair presentation of such Information. Subject to the exercise of professional judgment and except as expressly described herein, we have not attempted to verify independently the completeness, accuracy, or fair representation of any of the Information.

Senior officers of the Company have represented to RBC in a certificate delivered as of the date hereof, among other things, that (i) the Information provided orally by, or in the presence of, any officer or employee of the Company or in writing by the Company, any of its affiliates (as such term is defined in National Instrument 62-104 Take-Over Bids and Issuer Bids of the Canadian Securities Administrators) or any of their respective agents or advisors, for the purpose of preparing the Opinion was, at the date provided to RBC, and is at the date hereof complete, true and correct in all material respects, and did not and does not contain any untrue statement of a material fact, and did not and does not omit to state any material fact necessary to make such Information, or any statement contained therein, not misleading in light of the circumstances in which it was provided to RBC, and (ii) since the dates on which the Information was provided to RBC, except as disclosed in writing to RBC, there has been no material change or change in material facts, financial or otherwise, which might reasonably be considered material to the Opinion.

In preparing the Opinion, RBC has made several assumptions, including that all of the conditions required to implement the Substantial Issuer Bid will be met, that there will be no significant change in the holdings of the Shares other than as a result of the Substantial Issuer Bid and that the disclosure provided or incorporated by reference in the Draft Offer to Purchase with respect to the Company, its subsidiaries and affiliates and the Substantial Issuer Bid is accurate in all material respects.

The Opinion is rendered on the basis of securities markets, economic, financial and general business conditions prevailing as at the date hereof and conditions affecting the Company and the Shares at the date hereof.

The Opinion has been provided for the use of the Special Committee and the Board and may not be used by any other person or relied upon by any other person other than the Special Committee and the Board without the express prior written consent of RBC. The Opinion is given as of the date hereof and RBC disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Opinion which may come or be brought to RBC’s attention after the date hereof. Without limiting the foregoing, in the event that there is any material change in any fact or matter affecting the Opinion after the date hereof, RBC reserves the right to change, modify, or withdraw the Opinion.

RBC believes that its analyses must be considered as a whole and that selecting portions of the analyses or the factors considered by it, without considering all factors and analyses together, could create a misleading view of the process underlying the Opinion. The preparation of an opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Any attempt to do so could lead to undue emphasis on any particular factor or analysis. The Opinion is not to be construed as a recommendation to any holder of Shares as to whether to tender their Shares to the Substantial Issuer Bid, or as an opinion as to the fairness, from a financial point of view, of the consideration offered to holders of Shares pursuant to the Substantial Issuer Bid or as a formal valuation of the Shares or of any of the Company’s other securities or assets.

For purposes of the Opinion, the phrase “liquid market” has the meaning ascribed thereto in MI 61-101.

RBC CAPITAL MARKETS

Conclusion

Based upon and subject to the foregoing, RBC is of the opinion that, as of the date hereof, (i) a liquid market for the Shares exists, and (ii) it is reasonable to conclude that, following the completion of the Substantial Issuer Bid, there will be a market for holders of the Shares who do not tender to the Substantial Issuer Bid that is not materially less liquid than the market that existed at the time of the making of the Substantial Issuer Bid.

SHAREHOLDERS SHOULD CAREFULLY CONSIDER THE INCOME TAX CONSEQUENCES OF DEPOSITING SHARES PURSUANT THE OFFER. SEE SECTION 13 OF THE CIRCULAR “INCOME TAX CONSIDERATIONS”.

This Letter of Transmittal, properly completed and duly executed, together with all other required documents, must accompany the certificates for the Shares tendered pursuant to the Offer. Any financial institution that is a participant in CDS or DTC may make book-entry delivery of the Shares through the on-line tendering systems of such clearing systems pursuant to which book-entry transfers may be effected by causing the applicable clearing systems to transfer such shares into the Depositary’s account in accordance with such clearing system’s procedures for such transfer.

Subject to and effective upon acceptance for purchase of the Shares deposited hereby in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of Imperial, all rights, title and interest in and to all Shares deposited hereby pursuant to an Auction Tender or a Purchase Price Tender, or the portion of such Shares subject to purchase pursuant to a Proportionate Tender, and in and to any and all rights, benefits and claims in respect thereof or arising, or having arisen as a result of the undersigned’s status as a Shareholder of Imperial and in and to any and all distributions, payments, securities, rights, assets or other interests which may be declared, paid, issued, distributed, made or transferred, or may be payable, issuable, distributable or transferable, on or in respect of such shares or any of them on or after the date upon which the Shares are taken up and paid for pursuant to the Offer (the “Effective Time”), other than any dividends declared with a record date prior to the Effective Time and paid after the Effective Time, and hereby irrevocably constitutes and appoints the Depositary and any officer of Imperial as attorney-in-fact of the undersigned with respect to such Shares effective from the Effective Time, with full power of substitution (such power of attorney being an irrevocable power coupled with an interest), to:

(a)deliver certificates for such Shares, together with all accompanying evidences of transfer and authenticity, to or upon the order, of Imperial upon receipt by the Depositary, as the undersigned’s agent, of the Purchase Price (as defined below);

(b)present certificates for such Shares or DRIP positions for cancellation and transfer on the applicable securities register(s) of Imperial for such securities; and

(c)receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares, subject to the next paragraph, all in accordance with the terms of the Offer.

If the undersigned is tendering Shares held through the DRIP, the undersigned irrevocably appoints TSX Trust Company, acting as administrative agent for the DRIP as his or her agent for the purpose of tendering the Shares in accordance with the instructions set out in this Letter of Transmittal, effective as of the date hereof.

The undersigned hereby represents, warrants and covenants that:

(a)the undersigned understands that depositing Shares under any one of the procedures described in the Offer and the Instructions hereto will constitute the undersigned’s acceptance of the terms and conditions of the Offer, including the undersigned’s representation that (i) the undersigned has a “net long position” in shares being tendered or equivalent securities at least equal to the shares tendered within the meaning of Rule 14e-4 under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (ii) such tender of shares complies with Rule 14e-4 under the Exchange Act;

(b)the undersigned has full power and authority to deposit, sell, assign and transfer the Shares;

- 4 -

(c)when and to the extent Imperial accepts the Shares for payment, Imperial will acquire good, marketable, and unencumbered title thereto, free and clear of all liens, charges, encumbrances, security interests, claims, restrictions and equities whatsoever, together with all rights and benefits arising therefrom, and the same will not be subject to any adverse claim, provided that any dividends or distributions which may be declared, paid, issued, distributed, made or transferred on or in respect of such Shares to Shareholders of record on or prior to the Effective Time shall be for the account of the undersigned;

(d)on request, the undersigned will execute and deliver any additional documents that the Depositary or Imperial deems necessary or desirable to complete the assignment, transfer, and purchase of the Shares tendered hereby; and

(e)the undersigned has received and agrees to all of the terms of this Offer.

The names and addresses of the registered owners should be printed as they appear on the certificates representing Shares deposited hereby. The certificates, the number of Shares that the undersigned wishes to tender, whether the tender is being made as an Auction Tender, a Purchase Price Tender or a Proportionate Tender, and, if the tender is made as an Auction Tender, the Purchase Price at which such shares are being tendered, should all be indicated in the appropriate boxes. If the tender is being made pursuant to an Auction Tender, the Purchase Price at which such shares are being tendered should be indicated in Box G “Auction Tenders” below. If the tender is being made pursuant to a Proportionate Tender, the total number of Shares owned by the Shareholder MUST be indicated in Box B “Proportionate Tender” below.

The undersigned understands that he or she must indicate whether he or she tenders Shares pursuant to an Auction Tender, a Purchase Price Tender or a Proportionate Tender by completing the Box A “Type of Tender” below. All Shares tendered by a Shareholder who fails to specify any Auction Tender price for its Shares, or fails to indicate that he or she has tendered its Shares pursuant to a Purchase Price Tender or a Proportionate Tender, will be considered to have been tendered pursuant to a Purchase Price Tender. A shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender.

The undersigned understands that, upon the terms and subject to the conditions of the Offer, the Company will determine the purchase price (the “Purchase Price”), representing a single price per Share (which will not be less than $78.50 and not more than $94.00 per Share and in increments of $0.25 per Share) that it will pay for Shares validly deposited pursuant to the Offer and not withdrawn. The Purchase Price will be the lowest price that enables the Company to purchase that number of Shares pursuant to valid Auction Tenders and Purchase Price Tenders and not withdrawn having an aggregate purchase price not exceeding the Auction Tender Limit Amount, being an amount equal to (i) $1,500,000,000 less (ii) the product of (A) $1,500,000,000 and (B) a fraction, the numerator of which is the aggregate number of Shares owned by Shareholders making valid Proportionate Tenders, and the denominator of which is the aggregate number of Shares outstanding at the time of the Expiration Date. For the purpose of determining the Purchase Price, Shares tendered pursuant to a Purchase Price Tender will be considered to have been tendered at a price of $78.50 per Share (which is the minimum price per Share under the Offer). If the Purchase Price is determined to be $78.50 (which is the minimum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 19,108,280 Shares. If the Purchase Price is determined to be

$94.00 (which is the maximum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 15,957,446 Shares. Shares tendered pursuant to a Proportionate Tender will be considered to have been tendered at a price per share equal to the Purchase Price. Shares validly deposited pursuant to an Auction Tender will only be taken up if the price specified in the Auction Tender by the depositing shareholder is equal to or less than the Purchase Price. If no Auction Tenders or Purchase Price Tenders are made pursuant to the Offer, no Shares will be purchased by the Company (unless all Shareholders make valid Proportionate Tenders, in which case all Shares purchased will be purchased for $78.50 per Share).

The undersigned understands that if less than all of the Shares deposited are taken up by the Company (including Shares tendered pursuant to an Auction Tender at prices greater than the Purchase Price and Shares not purchased because of pro-ration), or properly withdrawn before the Expiration Date, the certificate(s) representing its Shares will be returned (in the case of certificates representing Shares all of which are not purchased) or replaced with new certificates representing the balance of Shares not purchased (in the case of certificates representing Shares of which less than all are purchased), promptly after the Expiration Date or the date of withdrawal, without expense to the Shareholder. DRIP positions not purchased, including DRIP positions not purchased due to proration and DRIP positions deposited pursuant to Auction Tenders at prices in excess of the Purchase Price, will be returned to the DRIP account promptly after the Expiration Date or the date of withdrawal, without expense to the Shareholder.

- 5 -

The undersigned understands that a Shareholder who desires to tender different Shares at more than one price under an Auction Tender must complete a separate Letter of Transmittal for each price at which Shares are tendered. A Shareholder may not deposit the same Shares pursuant to more than one method of tender or pursuant to an Auction Tender at more than one price. Shareholders may deposit different Shares pursuant to Auction Tenders and Purchase Price Tenders but cannot make an Auction Tender or Purchase Price Tender as well as a Proportionate Tender. Odd Lot Holders making an Auction Tender or a Purchase Price Tender will be required to tender all Shares owned by the Shareholder. Proportionate Tenders or partial tenders will not be accepted from Odd Lot Holders.

The undersigned understands that if the aggregate purchase price for the Shares tendered pursuant to Auction Tenders (at prices at or below the Purchase Price) and Purchase Price Tenders exceeds the Auction Tender Limit Amount, then the Company shall purchase a portion of the Shares so tendered pursuant to Auction Tenders (at or below the Purchase Price) and Purchase Price Tenders, as follows: (i) first, the Company will purchase all Shares tendered at or below the Purchase Price by Odd Lot Holders at the Purchase Price; and (ii) second, the Company will purchase at the Purchase Price on a pro-rata basis that portion of the Shares tendered pursuant to Auction Tenders (at or below the Purchase Price) and Purchase Price Tenders having an aggregate purchase price, based on the Purchase Price, equal to (A) the Auction Tender Limit Amount, less (B) the aggregate amount paid by the Company for shares tendered by Odd Lot Holders. See Section 3 of the Offer, “Number of Shares, Proration and Proportionate Tenders”. The Company’s determination as to pro-ration shall be final and binding on all parties.

The undersigned recognizes that under certain circumstances set forth in the Offer and the Circular, Imperial may withdraw, extend or vary the Offer or may not be required to purchase any of the Shares tendered hereby or may accept for payment, in accordance with the applicable proration provisions relating to Shares deposited or the terms and conditions relating to the Offer, fewer than all of the Shares tendered hereby. The undersigned understands that certificates for any Shares not deposited or not purchased will be recredited or returned to the undersigned at the address indicated above.

The undersigned understands that acceptance of Shares by Imperial for payment will constitute a binding agreement between the undersigned and Imperial, effective as of the Expiration Date, upon the terms and subject to the conditions of the Offer. Such agreement will be governed by and construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein.

The undersigned understands that payment for Shares taken up by the Company pursuant to the Offer will be made by depositing the aggregate Purchase Price for such Shares with the Depositary, which will act as agent for Shareholders who have properly tendered Shares in acceptance of the Offer and have not withdrawn them, for the purpose of receiving payment from Imperial and transmitting such payment to such Shareholders. Receipt of payment by the Depositary will be deemed to constitute receipt of payment thereof by persons depositing Shares. Under no circumstances will interest accrue or be paid by Imperial or the Depositary, regardless of any delay in making such payment or otherwise.

The undersigned understands and acknowledges that each of the Company and the Depositary, as applicable, shall be entitled to deduct and withhold from any payment to any Shareholder pursuant to the Offer such amount as it is required to deduct or withhold from such payment under the Income Tax Act (Canada) (the “Tax Act”), or any provision of any applicable federal, provincial, territorial, state, local or foreign tax law, and remit such deduction or withholding amount to the appropriate government entity. To the extent that amounts are deducted or withheld, such deducted or withheld amounts shall be treated for all purposes of the Offer as having been paid to the Shareholder to whom such amounts would otherwise have been paid, provided that such deducted or withheld amounts are actually remitted to the appropriate government entity.

The undersigned instructs Imperial and the Depositary to issue the cheque for the Purchase Price for such Shares that are purchased pursuant to the Offer as indicated in Box C or D “Payment Instructions” below and mailed by first- class mail, postage prepaid, to the address indicated in Box C or D “Delivery Instructions” below unless otherwise indicated in Box C “Hold for Pick-Up” below, subject to the option of Shareholders to elect to receive the Purchase Price in U.S. dollars as described in Box H “Currency Election” below, net in each case of any applicable withholding taxes.

The undersigned understands that cash amounts will be denominated in Canadian dollars and payments of amounts owing to Shareholders whose Shares are taken up will be made in Canadian dollars; however, Shareholders may elect to receive the Purchase Price in U.S. dollars and use the Depositary’s currency exchange services to convert such payment into U.S. dollars by checking Box H “Currency Election” below, in which case such Shareholder will have acknowledged and agreed that the exchange rate for one Canadian dollar expressed in U.S. dollars will be based on the rate available from the Depositary on the date of the currency conversion. All risks associated with the

- 6 -

currency conversion from Canadian dollars to U.S. dollars, including risks relating to change in rates, the timing of exchange or the selection of a rate for exchange, and all costs incurred with the currency conversion are for the Shareholder’s sole account and will be at such Shareholder’s sole risk and expense, and neither the Depositary nor Imperial or their affiliates will be responsible for any such matters.

The undersigned recognizes that all authority conferred or agreed to be conferred in this Letter of Transmittal shall survive its death or incapacity and any obligations of the undersigned under this Letter of Transmittal shall be binding upon its heirs, personal representatives, successors and assigns. Except as stated in the Offer, this tender is irrevocable.

The undersigned agrees not to vote any of the deposited Shares, or distributions on such Shares consisting of securities, at any meeting and not to exercise any of the other rights or privileges attached to any of such deposited Shares or distributions consisting of securities, or otherwise act with respect thereto. The undersigned agrees further to execute and deliver to Imperial, provided not contrary to any applicable law, at any time and from time to time, as and when requested by, and at the expense of Imperial, any and all instructions of proxy, authorization or consent, in form and on terms satisfactory to Imperial, in respect of any such deposited Shares or distributions consisting of securities. The undersigned agrees further to designate in any such instruments of proxy the person or persons specified by Imperial as the proxyholder of the undersigned in respect of such deposited Shares or distributions consisting of securities.

BOX A TYPE OF TENDER CHECK ONLY ONE BOX, IF MORE THAN ONE BOX IS CHECKED, OR IF NO BOX IS CHECKED, THE TENDER WILL BE DEEMED TO BE A PURCHASE PRICE TENDER. SHARES ARE BEING TENDERED HEREBY PURSUANT TO:
☐An Auction Tender	☐A Purchase Price Tender	☐a Proportionate Tender
(Complete Box G)		(Complete Box B)


BOX B PROPORTIONATE TENDER In addition to checking “Proportionate Tender” in Box A above, this Box B MUST be completed if Shares are being tendered pursuant to a Proportionate Tender. A Shareholder who makes a Proportionate Tender will be deemed to have agreed to sell to the Company at the Purchase Price a number of Shares that will result in the Shareholder maintaining its proportionate equity ownership in the Company following completion of the Offer. Registered Shareholders may make a Proportionate Tender and non-registered Shareholders may instruct their nominees to make a Proportionate Tender. All Shareholders who make a Proportionate Tender must indicate the total number of Shares they own below. A registered Shareholder who makes a Proportionate Tender must deposit either all of its Shares or a sufficient number of Shares to satisfy the Shareholder’s Proportionate Tender. This number of Shares can be calculated by multiplying the total number of Shares owned by the Shareholder by 0.0345 (rounded down to the nearest whole number of Shares). A non-registered Shareholder who wishes its nominee to make a Proportionate Tender must deposit all of its Shares. If a non-registered Shareholder wishes to become a registered Shareholder in order to make a Proportionate Tender by depositing only a sufficient number of Shares, the Shareholder should immediately contact its investment dealer, stock broker, bank, trust company or other nominee in order to take the necessary steps to have its Shares registered in the Shareholder’s name prior to tendering Shares pursuant to the Offer. A Shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender.

INSTRUCTIONS

Forming Part of the Terms of the Offer

1.Guarantee of Signatures.

No signature guarantee is required if:

(a)this Letter of Transmittal is signed by the registered Shareholder exactly as the name of the registered holder appears on the certificate or DRIP position deposited with this Letter of Transmittal and payment and delivery are to be made directly to such registered holder pursuant to Box C or D above; or

(b)such Shares are deposited for the account of a Canadian Schedule I chartered bank, a member of the Securities Transfer Agents Medallion Program (STAMP), a member of the Stock Exchange Medallion Program (SEMP) or a member of the New York Stock Exchange Inc. Medallion Signature Program (MSP) (each such entity, an “Eligible Institution”).

In all other cases, an Eligible Institution must guarantee all signatures on this Letter of Transmittal by completing Box K “Guarantee of Signature(s)”. See Instruction 6.

2.Delivery of Letter of Transmittal and Certificates — Guaranteed Delivery Procedures.

Certificates for all physically tendered Shares, together with a properly completed and duly executed Letter of Transmittal, or, in the case of a book-entry transfer, a Book-Entry Confirmation through the CDSX system (in the case of Shares held in CDS) or an Agent’s Message (in the case of Shares held in DTC), and any other documents required by this Letter of Transmittal, should be hand delivered, couriered or mailed to the Depositary at the appropriate address set forth herein and must be received by the Depositary by the Expiration Date.

Shareholders whose certificates are not immediately available or who cannot deliver certificates for Shares and all other required documents to the Depositary by the Expiry Date, may only tender their Shares by or through any Eligible Institution by properly completing and duly executing and delivering a Notice of Guaranteed Delivery substantially in the form provided (or an executed facsimile thereof) by the Company through the Depositary (indicating the type of tender and, in the case of an Auction Tender, the price at which Shares are being tendered) to the Depositary by the Expiry Date, which must include a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery, and by otherwise complying with this guaranteed delivery procedure as set forth in Section 5 of the Offer, “Procedure for Depositing Shares”. Pursuant to such guaranteed delivery procedure, the certificates for all physically tendered Shares, as well as a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof) or Book-Entry Confirmation or Agent’s Message in lieu thereof, relating to such Shares, with signatures guaranteed if so required in accordance with this Letter of Transmittal, and all other documents required by this Letter of Transmittal, must be received by the Toronto, Ontario office of the Depositary before 5:00 p.m. (Calgary time) on or before the second trading day on the Toronto Stock Exchange after the Expiration Date.

The Notice of Guaranteed Delivery may be hand delivered, couriered, mailed or transmitted by email transmission to the Toronto office of the Depositary listed in the Notice of Guaranteed Delivery, and must include a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery. For Shares to be validly tendered pursuant to the guaranteed delivery procedure, the Depositary must receive the Notice of Guaranteed Delivery by the Expiration Date.

Notwithstanding any other provision hereof, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of certificates for such Shares, a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof) relating to such Shares, with signatures that are guaranteed if so required, and any other documents required by the Letter of Transmittal or, in the case of a book-entry transfer, a Book- Entry Confirmation through the CDSX system (in the case of Shares held in CDS) or an Agent’s Message (in the case of Shares held in DTC).

- 13 -

The tender information specified in a Notice of Guaranteed Delivery will, in all circumstances, take precedence over the tender information that is specified in the related Letter of Transmittal that is subsequently deposited.

The method of delivery of certificates representing Shares and all other required documents is at the option and risk of the depositing Shareholder. If certificates representing Shares are to be sent by mail, registered mail, properly insured, is recommended, and it is suggested that the mailing be made sufficiently in advance of the Expiration Date to permit delivery to the Depositary on or prior to such date. Delivery of a certificate representing Shares will only be made upon actual receipt of such certificate representing such shares by the Depositary.

Under no circumstances will interest be paid by Imperial by reason of any delay in making payment to any person using the guaranteed delivery procedures, including without limitation any delay arising because the Shares to be delivered pursuant to the guaranteed delivery procedures are not so delivered to the Depositary, and therefore payment by the Depositary on account of such Shares is not made until after the date the payment for the deposited Shares accepted for payment pursuant to the Offer is to be made by Imperial.

Imperial will not purchase any fractional Shares, nor will it accept any alternative, conditional or contingent tenders except as specifically permitted by the Offer. All tendering Shareholders, by execution of this Letter of Transmittal and delivery of it in the manner prescribed herein, waive any right to receive any notice of the acceptance of their deposit.

3.Inadequate Space.

If the space provided in any Box is inadequate, attach a separate signed document to this Letter of Transmittal.

4.Indication of Type of Tender and Indication of Price.

(a)For Shares to be validly tendered, a Shareholder must indicate in Box A “Type of Tender” above whether he or she is tendering Shares pursuant to an Auction Tender (Box G “Auction Tenders”), a Purchase Price Tender or a Proportionate Tender (Box B “Proportionate Tender”).

(b)Only one box in Box A “Type of Tender” may be checked. If more than one box is checked, or if no box is checked, the Shareholder will be deemed to have made a Purchase Price Tender. The same Shares cannot be tendered, unless previously properly withdrawn as provided in the Offer and the Circular, pursuant to Auction Tenders at more than one price. Shareholders may not include the same Shares pursuant to more than one method of tender or pursuant to an Auction Tender at more than one price. Shareholders who desire to tender different Shares at more than one price under an Auction Tender must complete a separate Letter of Transmittal (or make a separate electronic book-entry confirmation) for each price at which Shares are tendered. Shareholders may deposit some of their Shares pursuant to an Auction Tender and deposit different Shares pursuant to a Purchase Price Tender. Shareholders who make an Auction Tender and/or a Purchase Price Tender cannot deposit Shares in a Proportionate Tender. Shareholders who deposit Shares in a Proportionate Tender may not make an Auction Tender or a Purchase Price Tender.

(c)For Shares to be validly tendered pursuant to an Auction Tender, a Shareholder must check the box indicating the price per Share at which he or she is tendering Shares under Box G “Auction Tenders”. Only one box in Box A may be checked. If more than one box is checked, or if no box is checked, the Shareholder will be deemed to have made a Purchase Price Tender. Shareholders (other than Odd Lot Holders) may make multiple Auction Tenders but not in respect of the same Shares. If a Shareholder wishes to tender different Shares at different prices, a separate tender instruction by way of Letter of Transmittal (or Book-Entry Confirmation or Agent’s Message as the case may be) must be submitted for each such tender. The same Shares cannot be tendered (unless previously withdrawn as provided in Section 6 of the Offer, “Withdrawal Rights”) pursuant to Auction Tenders at more than one price.

(d)No price can be specified by a Shareholder making a Purchase Price Tender or a Proportionate Tender. If a Shareholder checks “Purchase Price Tender” or “Proportionate Tender” under Box A

- 14 -

“Type of Tender” and indicates a price per Share in Box G “Auction Tenders”, there is no proper tender of Shares.

(e)For Shares to be properly tendered pursuant to a Proportionate Tender, the Shareholder must complete Box B “Proportionate Tender” on this Letter of Transmittal indicating the total number of Shares they own. A registered Shareholder who makes a Proportionate Tender must deposit either all of its Shares or a sufficient number of Shares to satisfy the Shareholder’s Proportionate Tender. This number of Shares can be calculated by multiplying the total number of Shares owned by the Shareholder by 0.0345 (rounded down to the nearest whole number of Shares). A non-registered Shareholder who wishes its nominee to make a Proportionate Tender must deposit all of its Shares. If a non-registered Shareholder wishes to become a registered Shareholder in order to make a Proportionate Tender by depositing only a sufficient number of Shares, the Shareholder should immediately contact its investment dealer, stock broker, bank, trust company or other nominee in order to take the necessary steps to have its Shares registered in the Shareholder’s name prior to tendering Shares pursuant to the Offer. A Shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender.

5.Partial Deposits and Unpurchased Shares.

If fewer than all of the Shares evidenced by any certificate are to be tendered pursuant to an Auction Tender or a Purchase Price Tender, fill in the number of Shares which are to be deposited in the column entitled “Number of Shares Deposited”. If you desire to deposit only a portion of your DRIP position, you must withdraw that portion of your DRIP position from the DRIP and submit the certificate received in respect thereof, together with a Letter of Transmittal. Shareholders should contact the DRIP plan agent, TSX Trust Company, in such circumstance to arrange the withdrawal. In such case, if any tendered Shares or Shares represented by DRIP positions are purchased, a new certificate for the remainder of the Shares evidenced by the old certificate(s) or DRIP position will be issued and sent to the address on record unless otherwise indicated under Box C “Payment Instructions” or Box D “Delivery Instructions” on this Letter of Transmittal, as soon as practicable after the Expiration Date. Prorated DRIP positions not purchased will be returned to the DRIP.

All Shares represented by the certificate(s) or DRIP positions listed and delivered to the Depositary are deemed to have been deposited unless otherwise indicated. For all Proportionate Tenders, a new certificate for the portion of the Shares that are not purchased pursuant to the Offer will be sent to the registered address on record unless otherwise indicated under Box C “Payment Instructions” or Box D “Delivery Instructions” on this Letter of Transmittal, as soon as practicable after the Expiration Date. Prorated DRIP positions not purchased will be returned to the DRIP.

6.Signatures on Letter of Transmittal, Stock Transfer Powers and Endorsements.

(a)If this Letter of Transmittal is signed by the registered holder(s) of the Shares deposited hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate without any change whatsoever.

(b)If the Shares are registered in the names of two or more joint owners, each such owner must sign this Letter of Transmittal.

(c)If any deposited Shares are registered in different names on several certificates, it will be necessary to complete, sign, and submit as many separate Letters of Transmittal (or facsimile of it) as there are different registrations of certificates.

(d)When this Letter of Transmittal is duly executed by the registered owner(s) of the Shares listed and transmitted hereby, no endorsements of certificate(s) representing such Shares or separate stock powers are required unless payment is to be made, or the certificates or DRIP positions for Shares not tendered by the undersigned or not purchased by the Company, are to be issued, to a person other than the registered owner(s). Any signature(s) required on such certificates or stock powers must be guaranteed by an Eligible Institution. If this Letter of Transmittal is duly executed by a person other than the registered owner of the certificate(s) listed, the certificates or DRIP positions must be endorsed or accompanied by appropriate stock powers, signed exactly as the name(s) of the registered owner(s) appear(s) on the certificate or DRIP position, and signatures on such

- 15 -

certificate(s) or stock power(s) must be guaranteed by an Eligible Institution. An ownership declaration, which can be obtained from the Depositary, must also be completed and delivered to the Depositary. See Instruction 1 in this Letter of Transmittal.

(e)If this Letter of Transmittal or any certificates or stock transfer powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and must submit proper evidence satisfactory to Imperial of their authority so to act.

7.Odd Lots.

As described in Section 3 of the Offer, “Number of Shares, Proration and Proportionate Tenders”, if Imperial is to purchase less than all Shares tendered pursuant to Auction Tenders and Purchase Price Tenders by the Expiration Date, the Shares purchased first will consist of all Shares so tendered by any Shareholder who will own beneficially, as of the close of business on the Expiration Date, an aggregate of fewer than 100 Shares and who tenders all of its Shares under Auction Tenders at or below the Purchase Price or under Purchase Price Tenders. This preference will not be available unless Box E “Odd Lots” is completed. Proportionate Tenders or partial tenders will not be accepted from Odd Lot Holders.

8.Special Payment Instructions.

Complete Box C “Payment Instructions” if cheques or new certificates or DRIP positions are to be sent to someone other than the undersigned.

If a cheque in payment for Shares tendered or new certificates are to be held by the Depositary for pick-up by the undersigned or any person designated by the undersigned in writing, Box C “Hold for Pick-Up” on this Letter of Transmittal must be completed.

The undersigned may elect to receive payment for shares tendered via a wire transfer instead of a cheque, by completing Box L – “Wire Payment”.

9.Lost Certificates

If a share certificate has been lost or destroyed, the shareholder must contact the Transfer Agent and receive a replacement share certificate prior to depositing the Letter of Transmittal with the Depositary. The Transfer Agent can be contacted by phone at 1 (800) 387-0825 or by email at lostcertificates@tmx.com.

10.Irregularities.

All questions as to the number of Shares to be taken up, the price to be paid therefor, the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any deposit of Shares will be determined by Imperial, in its sole discretion, which determination shall be final and binding on all parties. Imperial reserves the absolute right to reject any deposits of Shares determined by it not to be in proper form or completed in accordance with the instructions in the Offer and in this Letter of Transmittal or the acceptance for payment of or payment for which may, in the opinion of Imperial’s counsel, be unlawful. Imperial also reserves the absolute right to waive any of the conditions of the Offer or any defect or irregularity in the deposit of any particular Shares and Imperial’s interpretation of the terms of the Offer (including the instructions in the Offer and this Letter of Transmittal) will be final and binding on all parties. No individual deposit of Shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with deposits must be cured within such time as Imperial shall determine. None of Imperial, the Depositary, the Dealer Manager nor any other person is or will be obligated to give notice of defects or irregularities in notices of withdrawal, nor shall any of them incur any liability for failure to give any such notice. Imperial’s interpretation of the terms and conditions of the Offer (including this Letter of Transmittal and the Notice of Guaranteed Delivery) will be final and binding.

13.Form W-9.

Each U.S. Shareholder depositing Shares to the Depositary is required to provide the Depositary with a correct U.S. taxpayer identification number (“TIN”) (generally the Shareholder’s social security number or federal employer identification number) and certain other information, on Form W-9, which is attached to this Letter of Transmittal. Failure to timely provide a correct TIN on the form may subject the depositing Shareholder to U.S. federal backup withholding tax on the gross amount of any payments made to the U.S. Shareholder and, in certain cases, penalties.

14.Currency of Payment.

All amounts payable under the Offer will be paid in Canadian dollars; however, Shareholders can elect to use the Depositary’s currency exchange services to convert such payment into U.S. dollars by checking Box H “Currency Election”.

The exchange rate for one Canadian dollar expressed in U.S. dollars will be based on the rate available from the Depositary on the date of the currency conversion. All risks associated with the currency conversion from Canadian dollars to U.S. dollars, including risks relating to change in rates, the timing of exchange or the selection of a rate for exchange, and all costs incurred with the currency conversion are for the Shareholder’s sole account and will be at such Shareholder’s sole risk and expense, and neither the Depositary nor Imperial or their affiliates will be responsible for any such matters.

Non-resident Shareholders who do not properly complete and provide a Form NR-301 (or, in the case of a partnership or hybrid entity, Form NR-302 or NR-303, as applicable), will be assumed to be subject to 25% Canadian non- resident withholding tax rate on any relevant amounts.

This following is a summary only of certain U.S. tax considerations. Shareholders should consult with their tax advisors regarding the tax consequences with respect to their particular circumstances.

- 18 -

IMPORTANT U.S. TAX INFORMATION FOR U.S. HOLDERS

In order to avoid backup withholding of U.S. federal income tax on payments pursuant to the Offer, a U.S. Shareholder tendering Shares must, unless an exemption applies, provide the Depositary with such Shareholder’s TIN (i.e., Social Security Number or Employer Identification Number), certify under penalties of perjury that such TIN is correct, and provide certain other certifications by completing the Form W-9 included in this Letter of Transmittal. If a U.S. Shareholder does not provide such Shareholder’s correct TIN or fails to provide the required certifications, the Internal Revenue Service (the “IRS”) may impose a penalty of $50 U.S. dollars on such Shareholder and payment to such Shareholder pursuant to the Offer may be subject to backup withholding currently at a rate of 24%. All U.S. Shareholders tendering Shares pursuant to the Offer should complete and sign the Form W-9 to provide the information and certification necessary to avoid backup withholding (unless an applicable exemption exists and is proved in a manner satisfactory to Imperial and the Depositary).

Backup withholding is not an additional tax. Rather, the amount of the backup withholding can be credited against the

U.S. federal income tax liability of the person subject to the backup withholding, provided that the required information is given to the IRS. If backup withholding results in an overpayment of tax, a refund can be obtained by the Shareholder upon filing a U.S. federal income tax return.

Certain Shareholders (including, among others, corporations, individual retirement accounts and certain foreign individuals and entities) are generally not subject to backup withholding but may be required to provide evidence of their exemption from backup withholding. Exempt U.S. Shareholders should indicate their exempt status on the Form W-9. Shareholders are urged to consult their tax advisors to determine whether they are exempt from backup withholding and associated reporting requirements.

ALL U.S. SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE HOW THE FOREGOING BACKUP WITHHOLDING AND REPORTING REQUIREMENTS APPLY TO THEM WITH REGARD TO THEIR PARTICULAR CIRCUMSTANCES.

Exhibit (a)(1)(v)

This announcement is neither an offer to purchase nor a solicitation of an offer to sell the common shares of Imperial Oil Limited. The Offer (as defined below) is made solely by the Offer to Purchase, dated November 3, 2023, and the accompanying Issuer Bid Circular, and the related Letter of Transmittal, and Notice of Guaranteed Delivery and any amendments or supplements thereto. The Offer is not being made to holders of the Shares (as defined below) in any jurisdiction in which the making or acceptance of offers to sell the Shares would not be in compliance with the laws of that jurisdiction. In any jurisdiction where the securities, blue sky, or other laws require the Offer to be made by a licensed broker or dealer, the Offer shall be deemed made on behalf of Imperial Oil Limited by the Dealer Manager (as defined below) or one or more brokers or dealers registered under the laws of such jurisdiction.

Notice of Offer to Purchase for Cash by

Imperial Oil Limited of

Up to C$1,500,000,000 in Value of its Common Shares At a Purchase Price of

Not Less Than C$78.50 per Common Share

And Not More Than C$94.00 per Common Share

Imperial Oil Limited, a Canadian corporation (the “Company”), is offering to purchase for cancellation a number of the Company’s common shares (each, a “Share”), having an aggregate purchase price not exceeding C$1,500,000,000 pursuant to: (i) auction tenders in which the tendering shareholders specify the number of Shares being tendered at a specified price (the “Auction Price”) of not less than C$78.50 and not more than C$94.00 per Share in increments of C$0.25 per Share (the “Auction Tenders”), (ii) purchase price tenders, in which the tendering shareholders do not specify a price per Share, but rather agree to have a specified number of Shares purchased at the Purchase Price (as defined below) to be determined pursuant to the Offer to Purchase (as defined below) (the “Purchase Price Tenders”), or (iii) proportionate tenders, in which the tendering shareholders do not specify a price per Share, but rather agree to have a number of Shares purchased at the Purchase Price to be determined pursuant to the Offer to Purchase that will result in them maintaining their respective proportionate Share ownership (the “Proportionate Tenders), upon the terms and subject to the conditions described in the Offer to Purchase, dated November 3, 2023 (the “Offer to Purchase”), and the accompanying Issuer Bid Circular (the “Issuer Bid Circular”) and the related Letter of Transmittal (the “Letter of Transmittal”) and notice of guaranteed delivery (the “Notice of Guaranteed Delivery”) (which together, as they may be amended and supplemented from time to time, constitute the “Offer”).


THE OFFER WILL EXPIRE AT 5:00 P.M., CALGARY TIME, ON DECEMBER 8, 2023, OR AT SUCH LATER TIME AND DATE TO WHICH THE OFFER MAY BE EXTENDED BY THE COMPANY (THE “EXPIRATION DATE”), UNLESS WITHDRAWN.

The Offer is not conditional upon any minimum number of Shares being properly deposited under the Offer. The Offer is, however, subject to other conditions as set forth in the Offer to Purchase.

Upon the terms and subject to the conditions of the Offer, the Company will determine a single price per Share (the “Purchase Price”), not less than C$78.50 and not more than C$94.00 per Share (in increments of C$0.25 per Share),

that the Company will pay for Shares properly tendered to and not properly withdrawn from the Offer, taking into account the Auction Prices and the number of Shares deposited pursuant to Auction Tenders and Purchase Price Tenders. The Purchase Price will be the lowest price that enables the Company to purchase that number of Shares pursuant to valid Auction Tenders and Purchase Price Tenders having an aggregate purchase price not to exceed an amount (the “Auction Tender Limit Amount”) equal to (i) C$1,500,000,000 less (ii) the product of (A) C$1,500,000,000 and (B) a fraction, the numerator of which is the aggregate number of Shares owned by shareholders making valid Proportionate Tenders, and the denominator of which is the aggregate number of Shares outstanding at the time of the Expiration Date. All Shares the Company purchases in the Offer will be acquired at the same purchase price regardless of whether any shareholder tenders at a lower price. For the purpose of determining the Purchase Price, Shares tendered pursuant to a Purchase Price Tender will be considered to have been tendered at a price of $78.50 per Share (which is the minimum price per Share under the Offer). Shares tendered pursuant to a Proportionate Tender will be considered to have been tendered at a price per Share equal to the Purchase Price. Shares tendered by a Shareholder pursuant to an Auction Tender will not be purchased by the Company pursuant to the Offer if the price per Share specified by the Shareholder is greater than the Purchase Price. However, because of “odd lot” priority and proration described in the Offer to Purchase, the Company may not purchase all of the Shares tendered at or below the Purchase Price if the aggregate purchase price for Shares validly tendered and not withdrawn pursuant to Auction Tenders at Auction Prices at or below the Purchase Price and Purchase Price Tenders (the “Auction Tender Purchase Amount”) is greater than the Auction Tender Limit Amount. Shares not purchased in the Offer will be recredited or returned to the depositing shareholders at the Company’s expense promptly after the Expiration Date of the Offer. The Company reserves the right, in its sole discretion, to change the purchase price range per Share and to increase or decrease the value of Shares sought in the Offer, subject to applicable law.

As of October 30, 2023, there were 554,945,083 Shares issued and outstanding. At the maximum purchase price of C$94.00 per Share, the Company could purchase 15,957,446 Shares if the Offer is fully subscribed, which would represent approximately 2.9% of the issued and outstanding Shares as of October 30, 2023. At the minimum purchase price of C$78.50 per Share, the Company could purchase 19,108,280 Shares if the Offer is fully subscribed, which would represent approximately 3.4% of the issued and outstanding Shares as of October 30, 2023. The Shares are listed and posted for trading on the Toronto Stock Exchange (the “TSX”) under the symbol “IMO” and have unlisted trading privileges on the NYSE American LLC (“NYSE American”) under the symbol “IMO”.

Shareholders are urged to obtain current market quotations for the Shares before deciding whether and at what purchase price or purchase prices to tender their Shares.

The Company expressly reserves the right, in its sole discretion, at any time and from time to time, to extend the period of time during which the Offer is open or to vary the terms and conditions of the Offer by giving written notice, or oral notice to be confirmed in writing, of extension or variation to Computershare Investor Services, Inc., the depositary for the Offer (the “Depositary”), and by causing the Depositary to provide to all shareholders, where required by law, as soon as practicable thereafter, a copy of the notice in the manner set forth in the Offer to Purchase. Promptly after giving notice of an extension or variation to the Depositary, but, in the case of an extension, no later than 9:00 A.M., Calgary time, on the next Business Day (defined herein as any day other than a Saturday, a Sunday, a statutory holiday in Calgary, Alberta or Toronto, Ontario and a United States federal holiday) following the last previously scheduled or announced Expiration Date, the Company will make a public announcement of the extension or variation and provide or cause to be provided notice of such extension or variation to the TSX, NYSE American and the applicable Canadian securities regulatory authorities.

The Offer will expire at 5:00 P.M., Calgary time, on December 8, 2023, unless the Company exercises its right, in its sole discretion, to extend the period of time during which the Offer will remain open. Beneficial owners should be aware that their broker, dealer, commercial bank, trust company or other nominee may establish its own earlier deadlines for participation in the Offer. Accordingly, beneficial owners wishing to participate in the Offer should contact their broker, dealer, commercial bank, trust company or other nominee as soon as possible in order to determine the times by which such owner must take action in order to participate in the Offer.

In accordance with the instructions to the Letter of Transmittal, shareholders wishing to tender Shares must indicate whether he or she tenders Shares pursuant to an Auction Tender, a Purchase Price Tender or a Proportionate Tender. If electing to tender his or her Shares pursuant to an Auction Tender, the tendering shareholder must specify the number of Shares that it wishes to sell and the price, not greater than C$94.00 nor less than C$78.50 per Share, at


2

which he or she is willing to sell his or her Shares to the Company in the Offer. All Shares tendered by a shareholder who fails to specify any Auction Tender price for its Shares, or fails to indicate that he or she has tendered its shares pursuant to a Purchase Price Tender or a Proportionate Tender, will be considered to have been tendered pursuant to a Purchase Price Tender. A shareholder who makes an invalid Proportionate Tender, including by tendering an insufficient number of Shares, will be deemed to have made a Purchase Price Tender. Shareholders wishing to tender Shares must follow the procedures set forth in the Offer to Purchase, Issuer Bid Circular and in the related Letter of Transmittal (and, if applicable, the Notice of Guaranteed Delivery).

The Purchase Price will be payable in Canadian dollars; however, shareholders may elect to receive the Purchase Price in United States dollars as described in the Offer. The risk of any fluctuation in exchange rates, including risks relating to the particular date and time at which funds are converted, will be borne solely by the shareholder wishing to receive payment in United States dollars.

•first, the Company will purchase all Shares tendered at or below the Purchase Price by shareholders who own fewer than 100 Shares (the “Odd Lot Holders”) at the Purchase Price; and

•second, the Company will purchase at the Purchase Price on a pro rata basis that portion of the Shares tendered pursuant to Auction Tenders at or below the Purchase Price and Purchase Price Tenders having an aggregate purchase price, based on the Purchase Price, equal to (A) the Auction Tender Limit Amount, less (B) the aggregate amount paid by the Company for Shares tendered by Odd Lot Holders. Regardless of proration, the Company will always purchase at the Purchase Price, payable in cash (subject to applicable withholding taxes, if any), a number of Shares from shareholders making valid Proportionate Tenders that results in such tendering shareholders maintaining their respective proportionate Share ownership in the Company following completion of the Offer (subject to nominal differences due to the quantity of Shares purchased from such shareholders being rounded down to the nearest whole number of Shares to avoid the purchase of fractional Shares). Shareholders making Proportionate Tenders will be prorated in a separate proration pool from Shareholders making Auction Tenders and/or Purchase Price Tenders. Such proration will be based on the number of Shares necessary for such Shareholders to maintain their existing ownership percentages.

Payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (i) the share certificates for all Shares proposed to be taken up in proper form for transfer, together with a properly completed and duly executed Letter of Transmittal (or a manually executed photocopy thereof) or, in the case of a book-entry transfer, a Book-Entry Confirmation or an Agent’s Message (each as defined in the Offer to Purchase), as applicable, in lieu thereof relating to such Shares, with signatures that are guaranteed if so required in accordance with the Letter of Transmittal, and (ii) any other documents required by the Letter of Transmittal.

In the event of proration of Shares deposited pursuant to the Auction Tenders and Purchase Price Tenders, the Company will determine the proration factor and pay for those deposited Shares accepted for payment as soon as practicable after the Expiration Date. However, the Company does not expect to be able to announce the final results of any such proration until approximately three (3) Business Days after the Expiration Date.

Deposits of Shares are irrevocable, except that Shares may be withdrawn by the shareholder (a) at any time if the Shares have not been taken up by the Company before actual receipt by the Depositary of a notice of withdrawal in respect of such Shares, (b) at any time before the expiration of ten (10) days from the date that a notice of change or variation (unless (i) the Company has taken up the Shares deposited pursuant to the Offer before the date of the notice of change or variation, or (ii) the variation consists solely of an increase in the consideration offered for those Shares pursuant to the Offer where the time for deposit is not extended for greater than ten (10) days) has been given


3

in accordance with the terms of the Offer to Purchase; or (c) at any time if the Shares have been taken up but not paid for by the Company within three (3) Business Days of being taken up.

For a withdrawal to be effective, a written or printed copy of a notice of withdrawal must be actually received by the Depositary by the applicable date specified above at the place of deposit of the relevant Shares. Any such notice of withdrawal must be signed by or on behalf of the person who signed the Letter of Transmittal or Notice of Guaranteed Delivery in respect of the Shares being withdrawn or, in the case of shares tendered in accordance with the procedures for book-entry transfer described in the Offer to Purchase, any notice of withdrawal must be signed by such participant in the same manner as the participant’s name is listed on the applicable Book-Entry Confirmation or on the applicable Agent’s Message, and must specify the name of the person who deposited the shares to be withdrawn, the name of the registered holder, if different from that of the person who deposited such shares, and the number of shares to be withdrawn. If the certificates for the Shares deposited pursuant to the Offer have been delivered or otherwise identified to the Depositary, then, prior to the release of such certificates, the depositing shareholder must submit the serial numbers shown on the particular certificates evidencing the shares to be withdrawn and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in the Offer to Purchase), except in the case of shares deposited by an Eligible Institution. All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by the Company, in its sole discretion, which determination shall be final and binding. None of the Company, the Depositary, RBC Capital Markets, as dealer manager (the “Dealer Manager”), or any other person shall be obligated to give any notice of any defects or irregularities in any notice of withdrawal and none of them shall incur any liability for failure to give any such notice.

Generally, if a shareholder is a Resident Shareholder (as defined in the Offer to Purchase), Shares will be considered to be capital property to the Resident Shareholder provided that the Resident Shareholder does not hold the Shares in the course of carrying on a business and has not acquired the Shares in one or more transactions considered to be an adventure or concern in the nature of trade. A Resident Shareholder whose Shares might not otherwise qualify as capital property may, in certain circumstances, make an irrevocable election under subsection 39(4) of the Income Tax Act (Canada) (the “Tax Act”) to have the Shares and every other “Canadian security”, as defined in the Tax Act, owned by such Resident Shareholder in the taxation year of the election and in all subsequent taxation years deemed to be capital property. Resident Shareholders are advised to consult their own tax advisors to determine if this election is appropriate in their particular circumstances.

A Resident Shareholder who disposes of Shares pursuant to the Offer will be deemed to receive a taxable dividend on a separate class of shares comprising the Shares so sold equal to the excess of the amount paid by the Company for the Shares, being the Purchase Price, over their paid-up capital for purposes of the Tax Act. The Company estimates that on the Expiration Date the paid-up capital per Share should not exceed $1.75 for purposes of the Tax Act. As a result, the Company expects that a Resident Shareholder who disposes of Shares under the Offer will be deemed to receive a taxable dividend. The exact quantum of the deemed dividend cannot be guaranteed.

A Non-Resident Shareholder (as defined in the Offer to Purchase) who disposes of Shares pursuant to the Offer will be deemed to receive a dividend equal to the excess of the amount paid by the Company for the Shares, being the Purchase Price, over their paid-up capital for Canadian income tax purposes. As a result, the Company expects that Non-Resident Shareholders who dispose of Shares under the Offer will be deemed to receive a dividend. The Company estimates that on the Expiration Date the paid-up capital per Share should not exceed $1.75 for purposes of the Tax Act. The exact quantum of the deemed dividend cannot be guaranteed. Any such dividend will be subject to Canadian withholding tax at a rate of 25% or such lower rate as may be provided under the terms of an applicable Canadian tax treaty.

Generally, the purchase of shares from a shareholder that is a U.S. Holder (as defined in the Issuer Bid Circular) will be a taxable transaction for U.S. federal income tax purposes. As a consequence of any such purchase, a U.S. Holder will, depending on the U.S. Holder’s particular circumstances, be treated either as having sold its Shares or as having received a distribution in respect of such Shares.

All shareholders should read carefully the Offer to Purchase and the accompanying Issuer Bid Circular for additional information regarding the income tax consequences of participating in the Offer and should consult their financial and tax advisors.

The Board of Directors has approved the Offer. However, none of the Company, the Special Committee (as defined in the Offer to Purchase) or the Board of Directors, the Dealer Manager or the Depositary makes any recommendation to any shareholder as to whether to deposit or refrain from depositing Shares under the Offer. Shareholders are urged to evaluate carefully all information in the Offer, consult their own financial, legal, investment and tax advisors and make their own decisions as to whether to deposit Shares under the Offer, how many Shares to deposit and whether to specify a price and, if so, at what price to deposit such Shares. No director or officer of the Company has advised the Company that he or she intends to deposit Shares under the Offer.

The information required to be disclosed by Rule 13e-4(d)(1) of the Securities Exchange Act of 1934, as amended, is contained in the Offer to Purchase and is incorporated herein by reference. The Company is also filing with the Securities and Exchange Commission an Issuer Tender Offer Statement on Schedule TO, which includes certain additional information relating to the Offer.

Copies of the Offer to Purchase, accompanying Issuer Bid Circular and the related Letter of Transmittal and Notice of Guaranteed Delivery are being mailed to all holders of the Shares, including brokers, dealers, commercial banks and trust companies whose names, or the names of whose nominees, appear on the Company’s shareholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares. The Offer is explained in detail in those materials.

Questions or requests for assistance may be directed to the Depositary or the Dealer Manager, at their respective addresses, telephone numbers and emails, as applicable and as set forth below. Copies of the Offer to Purchase, accompanying Issuer Bid Circular, the Letter of Transmittal, the Notice of Guaranteed Delivery and other related materials will be furnished promptly by the Depositary at the Company’s expense. Shareholders may also contact their broker, dealer, commercial bank, trust company or other nominee or trust company for assistance concerning the Offer.
