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 $72.50 and not more than $87.00 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 $72.50 per Share (which is the minimum price per Share under the Offer). If the Purchase Price is determined to be $72.50 (which is the minimum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 20,689,655 Shares. If the Purchase Price is determined to be $87.00 (which is the maximum price per Share under the Offer), the maximum number of Shares that may be purchased by the Company is 17,241,379 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 $72.50 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 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 0.0343 (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.

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 0.0343 (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.

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.

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.

How to complete this form Backup Withholding The Internal Revenue Service (IRS) requires us to withhold taxes for the applicable rate of backup withholding for U.S. persons without a W-9 tax certification who are not otherwise exempt. Parties acting as disbursement agents, such as Computershare, must withhold and pay to the IRS the applicable tax rate of such payments under certain conditions. This is called “backup withholding.” Payments that may be subject to backup withholding include interest, dividends, broker and barter exchange transactions, and royalties. Supplying us with your correct Taxpayer Identification Number (TIN), and signing this form will generally allow you to receive your payments without being subject to backup withholding. Failure to supply your TIN, or supplying us with an incorrect TIN, could result in a $50.00 penalty being assessed by the IRS. Receipt of a completed Form W-9 will discontinue backup withholding unless otherwise required. Taxpayer Identification Social Security Number (SSN) - If you are completing this on behalf of one of these parties, include the appropriate Social Security Number, as indicated below. 1.
