This letter of transmittal (the “Letter of Transmittal”) is to be used by registered shareholders (the “CanniMed Shareholders”) of common shares (the “CanniMed Shares”) of CanniMed Therapeutics Inc. (“CanniMed” or the “Company”) to accept the offer (the “Offer”) made by Aurora Cannabis Inc. (the “Offeror” or “Aurora”) to purchase, upon and subject to the terms and conditions of the Offer, all of the issued and outstanding CanniMed Shares (including any CanniMed Shares that may become issued and outstanding upon exercise of convertible securities after the date of the Offer but before the Expiry Time), as set out in the Offer and accompanying Take-Over Bid Circular of Aurora dated November 24, 2017 (together, the “Offer and Circular”), and to facilitate the deposit of CanniMed Shares pursuant to the Offer.

The terms and conditions of the Offer and Circular are incorporated by reference in this Letter of Transmittal and capitalized terms used but not defined in this Letter of Transmittal have the respective meanings set out in the Offer and Circular.

This Letter of Transmittal is to be used by CanniMed Shareholders only and is NOT to be used by beneficial holders of CanniMed Shares (each, a “Beneficial Shareholder”). A Beneficial Shareholder does not have CanniMed Shares registered in his, her or its name; rather, such CanniMed Shares are held by an intermediary or clearing agency such as CDS & Co. (each, an “Intermediary”). If you are a Beneficial Shareholder you should contact your Intermediary for instructions and assistance in receiving the consideration for your CanniMed Shares.

On the Effective Date, CanniMed Shareholders will be entitled to receive, in exchange for each CanniMed Share, 4.52586207 common shares of the Offeror (the “Aurora Shares”), subject to: (a) adjustment in accordance with the terms and conditions of the Offer, and (b) the Cap Price of $24.00 per CanniMed Share. (The Aurora Shares issuable in exchange for CanniMed Shares pursuant to the Offer are sometimes collectively referred to herein as the “Consideration”). CanniMed Shareholders are not entitled to receive fractional Aurora Shares in connection with the Offer and the number of Aurora Shares issuable to each CanniMed Shareholder pursuant to the Offer will be either rounded down to the nearest whole number (if the fractional interest is less than 0.5) or up to the nearest whole number (if the fractional interest is 0.5 or higher).

The Offer is subject to, among other things, the receipt of more than 66 2/3% of the CanniMed Shares validly tendered to the Offer and not withdrawn.

CanniMed Shareholders who wish to accept the Offer must, prior to the Expiry Time, complete and execute this Letter of Transmittal and tender it, or a manually executed facsimile thereof, together with the certificate(s) or DRS Statement(s) representing the CanniMed Shares and any other documents required by this Letter of Transmittal, to Laurel Hill Advisory Group Company, the depositary for the Offer (in such capacity, the “Depositary and Information Agent”), at the offices of the Depositary and Information Agent set out on the back page of this Letter of Transmittal. Detailed rules and instructions are set out below in this Letter of Transmittal. Alternatively, the CanniMed Shareholders may accept the Offer by:

(a)	following the procedures for book-entry transfer of the CanniMed Shares described in Section 3 of the Offer, “Manner of Acceptance – Procedure for Book-based Transfer”; or
(b)	following the procedures for guaranteed delivery described in Section 3 of the Offer, “Manner of Acceptance – Procedure for Guaranteed Delivery”, using the accompanying Notice of Guaranteed Delivery (printed on green paper) or a manually executed facsimile thereof.

CanniMed Shareholders who wish to accept the Offer will not be required to pay any fee or commission if they tender their CanniMed Shares directly to the Depositary and Information Agent. See Section 3 of the Offer, “Manner of Acceptance”.

Aurora will pay for CanniMed Shares validly deposited under the Offer and not withdrawn by providing a treasury direction to the Offeror’s transfer agent, Computershare Trust Company of Canada (“Computershare”), to issue a sufficient number of Aurora Shares for transmittal to depositing CanniMed Shareholders. Under no circumstances will interest accrue or be paid by Aurora or the Depositary and Information Agent to persons depositing CanniMed Shares on the purchase price of CanniMed Shares purchased by Aurora, regardless of any delay in making such payment. The Depositary and Information Agent will act as the agent of persons who have deposited CanniMed Shares in acceptance of the Offer for the purposes of receiving payment from Aurora and transmitting payment to such persons, and receipt of payment by the Depositary and Information Agent shall be deemed to constitute receipt thereof by persons depositing CanniMed Shares.

PLEASE READ THE OFFER AND CIRCULAR, AND THE INSTRUCTIONS SET OUT BELOW CAREFULLY BEFORE COMPLETING THIS LETTER OF TRANSMITTAL. DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN THE ADDRESS AS SET FORTH HEREIN WILL NOT CONSTITUTE A VALID DELIVERY. IF SHARES ARE REGISTERED IN DIFFERENT NAMES, A SEPARATE LETTER OF TRANSMITTAL MUST BE SUBMITTED FOR EACH DIFFERENT REGISTERED OWNER. SEE INSTRUCTION #9.

NOTICE TO U.S. SHAREHOLDERS

The exchange offer is made for the securities of a company formed outside of the United States. The Offer is subject to disclosure requirements of Canada that are different from those of the United States. Financial statements included or incorporated by reference in the Offer and Circular have been prepared in accordance with Canadian accounting standards and may not be comparable to the financial statements of United States companies.

It may be difficult for you to enforce your rights and any claim you may have arising under the U.S. federal Securities Laws, since the Offeror is located in Canada, and some or all of its officers or directors may be residents of Canada or another country outside of the United States. You may not be able to sue a Canadian company or its officers or directors in a court in Canada or elsewhere outside of the United States for violations of U.S. Securities Laws. It may be difficult to compel a Canadian company and its affiliates to subject themselves to a U.S. court’s judgment.

You should be aware that Offeror may purchase securities otherwise than under the Offer, such as in open market or privately negotiated purchases.

THESE SECURITIES HAVE NOT BEEN REGISTERED OR OTHERWISE QUALIFIED FOR OFFER AND SALE IN CERTAIN U.S. STATES WHERE HOLDERS OF CANNIMED SHARES RESIDE AND NO SUCH OFFER TO SELL OR SALE, OR SOLICITATION OF AN OFFER TO BUY MAY BE MADE IN SUCH U.S. STATES.

Holders of CanniMed Shares whose CanniMed Shares are registered in the name of a broker, investment dealer, bank, trust company or other nominee should contact that nominee for assistance in depositing those CanniMed Shares. Delivery to an office other than to the specified office in this Letter of Transmittal does not constitute delivery for this purpose.

(e)      If the DRS Statement in respect of the Aurora Shares is to be issued in the name of a person other than the person(s) signing this Letter of Transmittal or if the DRS Statement in respect of the Aurora Shares is to be mailed to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown above, the appropriate boxes in this Letter of Transmittal should be completed (Box A and Box B).

If the Offer does not proceed for any reason, any certificate(s) representing CanniMed Shares received by the Depositary and Information Agent will be returned to you forthwith in accordance with your delivery instructions in Box “A” or Box “B”.

8. Direct Registration System

Aurora Shares issuable under the Offer may be issued in the Direct Registration System, or DRS. The DRS is a system that allows you to hold your Aurora Shares in “book-entry” form without having a physical share certificate issued as evidence of ownership. Instead, your Aurora Shares will be held in your name and registered electronically in Aurora’s records, which will be maintained by its transfer agent, Computershare. The Direct Registration System eliminates the need for shareholders to safeguard and store certificates, it avoids the significant cost of a surety bond for the replacement of, and the effort involved in replacing, physical certificate(s) that might be lost, stolen or destroyed and it permits/enables electronic share transactions.

Upon completion of the Offer you may receive an initial DRS Statement acknowledging the number of Aurora Shares you hold in your DRS account. Each time you have any movement of shares into or out of your DRS account, you will be mailed an updated DRS Statement. You may request a statement at any time by contacting Computershare or by accessing your account online at www.computershare.com/investorcentrecanada.

At any time you may request a share certificate for all or a portion of the Aurora Shares held in your DRS account. Simply contact Computershare with your request. A share certificate for the requested number of Aurora Shares will be sent to you by first class mail upon receipt of your instructions, at no cost to you.

For more information about DRS, please contact Computershare at 1-800-564-6253 (toll free within Canada and the U.S.) or 514-982-7555 (outside of Canada and the U.S.) or visit Computershare on-line at www.computershare.com/investorcentrecanada.
