Prospective investors should be aware that the acquisition and disposition of the Securities may have tax
consequences both in the United States and in Canada. Such consequences for investors who are resident in, or citizens of, the United States are not described fully herein. Prospective investors should read the tax discussion contained in any
applicable Prospectus Supplement with respect to a particular Offering and consult their own tax advisor with respect to their own particular circumstances. See Certain Canadian and United States Income Tax Consequences.
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE SEC) NOR HAS THE SEC PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
All information permitted under
applicable law to be omitted from this Prospectus will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, except in cases where an exemption from such delivery requirements is
available. Each Prospectus Supplement will be incorporated by reference in this Prospectus for the purposes of securities legislation as of the date of the Prospectus Supplement and only for the purposes of the distribution of the Securities to
which the Prospectus Supplement pertains. You should read this Prospectus and any applicable Prospectus Supplement carefully before you invest in any Securities. The Corporation may offer and sell Securities through underwriters or dealers, directly
or through agents designated by the Corporation from time to time at amounts and prices and other terms determined by the Corporation. A Prospectus Supplement will set forth the names of any underwriters, dealers or agents involved in the Offering
and will set forth the terms of the Offering, the method of distribution of such Securities including, to the extent applicable, the proceeds to the Corporation and any fees, discounts or any other compensation payable to underwriters, dealers or
agents and any other material terms of the distribution. Unless otherwise specified in a Prospectus Supplement, in connection with any Offering, other than an
at-the-market distribution, the underwriters or agents may, subject to applicable law, over-allot or effect transactions which stabilize or maintain the
market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. No underwriter, agent or dealer of the at-the-market distribution, and no person or company acting jointly or in concert with an underwriter, agent or dealer, may, in connection with the distribution, enter into any transaction that is
intended to stabilize or maintain the market price of the Securities or Securities of the same class as the Securities distributed under the at-the-market
prospectus, including selling an aggregate number or principal amount of Securities that would result in the underwriter, agent or dealer creating an over-allocation position in the Securities. See Plan of Distribution. No underwriter
has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.
Investing in the Securities is
speculative and involves certain risks. The risks outlined in this Prospectus and in the documents incorporated by reference herein and in the applicable Prospectus Supplement and the documents incorporated by reference therein should be carefully
reviewed and considered by prospective investors. See Risk Factors.
The enforcement by investors of civil liabilities under the United
States federal securities laws may be affected adversely by the fact that the Corporation is incorporated in Canada, most of the Corporations directors and officers are residents of Canada, some of the experts named in this Prospectus are not
residents of the United States, and all or a substantial portion of the Corporations assets and the assets of such persons are located outside of the United States. See Enforceability of Certain Civil Liabilities.
Messrs. Michael Vitton and Raymond Threlkeld and Dr. William (Bill) Williams, each a director of the Corporation, and Daniel Roth, Michael G. Hester,
John M. Marek, Laurie M. Tahija, Patrick W. Dugan, each a qualified person named in this Prospectus, reside outside of Canada. Messrs. Michael Vitton and Raymond Threlkeld and Dr. William (Bill) Williams have each appointed Cassels
Brock & Blackwell LLP, Suite 2200, 885 West Georgia Street, Vancouver, British Columbia, V6C 3E8 for service of process. Prospective investors are advised that it may not be possible for investors to enforce judgments obtained in Canada
against any person that resides outside of Canada, even if the person has appointed an agent for service of process.
The Corporations common
shares (the Common Shares) are listed on the Toronto Stock Exchange (the TSX) and the NYSE American (the NYSE American) under the symbol WRN. Unless otherwise specified in the applicable Prospectus
Supplement, there is no existing trading market through which the warrants (the Warrants), the subscription receipts (the Subscription Receipts) or the units (the Units) may be sold and purchasers may not be able
to resell any of such Securities purchased under this Prospectus. This may affect the pricing of such Securities on the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer
regulation. See Risk Factors. No assurances can be given that a market for trading in Securities of any series or issue will develop or as to the liquidity of any such market, whether or not the Securities are listed on a securities
exchange.
