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 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, its Special Committee and its Board of Directors in determining to approve
the Offer, among other considerations, on or about May 6, 2022. 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.sedar.com 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.
Imperials Board of Directors has approved the making of the Offer and
the price range for the purchase of Shares thereunder upon the recommendation of its Special Committee. However, none of Imperial, its Special Committee, 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, 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.
The Offer referred to in this news release has not yet commenced. This news release is for informational purposes only and 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 Canada and 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. (Computershare) to act as depositary. Any questions or requests for information may be directed to Computershare at 1 (800) 564-6253 (Toll Free
