ACKNOWLEDGEMENTS AND AGREEMENTS OF THE SUBSCRIBER

no prospectus has been filed by the Issuer with any securities commission or any other regulatory authority in connection with the issuance of the Common Shares;

the Subscriber has not received, nor has the Subscriber requested nor had any need to receive, or been provided with a prospectus, offering memorandum or any document purporting to describe the business and affairs of the Issuer which has been prepared for review by prospective purchasers to assist in making an investment decision in respect of the Common Shares and that the Subscriber’s decision, or, if applicable, the decision of others for whom the undersigned is contracting hereunder, to enter into this Agreement and to subscribe for the Common Shares is based entirely upon this Agreement and publicly available information concerning the Issuer and not upon any other verbal or written representation as to fact or otherwise made by or on behalf of the Issuer;

the Issuer’s constating documents contain restrictions on the transfer of the Common Shares, which provide that no Common Shares may be transferred without the prior approval of the board of directors of the Issuer;

the Issuer is not a “reporting issuer” as that term is defined in applicable Canadian securities laws, nor will it become a reporting issuer in any jurisdiction in Canada or elsewhere upon completion of the Offering and, as a result:

any applicable hold periods under applicable securities laws may never expire, and the Common Shares may be subject to restrictions on resale for an indefinite period of time;

the Issuer is relieved from certain obligations that would otherwise apply under applicable securities laws,

there is no government or other insurance covering the Common Shares, and

there are risks associated with the purchase of the Common Shares, including that the Subscriber may lose the Subscriber’s entire investment;

an investment in the Issuer is highly speculative and only investors who can afford the loss of their entire investment should consider investing in the Issuer and the Common Shares;

any subscription monies paid by the Subscriber for the Common Shares is being raised as “seed” or “risk” capital for the Issuer, which is in a speculative stage, and there is no market for the Common Shares whatsoever;

none of the Common Shares have been or will be registered under the United States Securities Act of 1933, as amended (the “1933 Act”), or under any securities or “blue sky” laws of any state of the United States, and, unless so registered, may not be offered or sold in the United States or, directly or indirectly, to any U.S. Person (as defined in Section 6.2) except in accordance with the provisions of Regulation S under the 1933 Act (“Regulation S”), pursuant to an effective registration statement under the 1933 Act, or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the 1933 Act, and in each case only in accordance with any other applicable state, provincial and foreign securities laws;

the Issuer has not undertaken, and will have no obligation, to register any of the Common Shares under the 1933 Act or any other securities laws;

the Issuer will refuse to register the transfer of any of the Common Shares to a U.S. Person not made pursuant to an effective registration statement under the 1933 Act or pursuant to an available exemption from the registration requirements of the 1933 Act, and in each case will only register such transfer in accordance with Applicable Laws;

any resale, assignment, transfer, hypothecation or pledge of any of the Common Shares by the Subscriber will be subject to: (i) resale restrictions contained in the securities laws applicable to the Issuer, the Subscriber and any proposed transferee; and (ii) the Issuer’s constating documents and it is the responsibility of the Subscriber to find out what those restrictions are and to comply with such restrictions before selling any of the Common Shares;

it consents to the placement of a legend or legends on the Certificate and any other document evidencing any of the Common Shares setting forth the restrictions on transferability and sale thereof contained in this Agreement, including the following:

it has been advised to consult its own legal, tax and other advisors with respect to the Offering and the risks of an investment in the Common Shares and with respect to applicable resale restrictions, and it is solely responsible (and the Issuer is not in any way responsible) for compliance with:

any Applicable Laws of the jurisdiction in which the Subscriber is resident in connection with the distribution of the Common Shares hereunder, and

any applicable resale restrictions;

there may be material tax consequences to the Subscriber of an acquisition or disposition of the Common Shares and the Issuer gives no opinion and makes no representation to the Subscriber with respect to the tax consequences to the Subscriber under federal, state, provincial, local or foreign tax laws that may apply to the Subscriber’s acquisition or disposition of any of the Common Shares;

the Issuer is relying on one of the “Accredited Investor” exemption or the “Minimum Amount Investment” exemption from the prospectus requirements as set out in National Instrument 45-106 – Prospectus Exemptions (“NI 45-106”) adopted by the Canadian Securities Administrators or subsection 73.4(2) of the Securities Act (Ontario), as applicable, which, among other restrictions, impose: (i) a transfer restriction on the Common Shares to the effect that, for so long as the Issuer is not a reporting issuer, the Common Shares are subject to restrictions on transfer that are contained in the Issuer’s constating documents; and (ii) a requirement to legend the Certificate representing the Common Shares to reflect such transfer restriction;

there is no market for any of the Common Shares and no market for any of the Common Shares may ever exist; and
