**ITEM 16G. CORPORATE GOVERNANCE**

The Company is a "foreign private issuer" as defined in Rule 3b-4 under the Exchange Act and the Common Shares are listed on Nasdaq. Rule 5615(a)(3) of The Nasdaq Stock Market Rules permits foreign private issuers to follow home country practices in lieu of certain provisions of The Nasdaq Stock Market Rules. A foreign private issuer that follows home country practices in lieu of certain provisions of Nasdaq Stock Market Rules must disclose ways in which its corporate governance practices differ from those followed by domestic companies either on its website or in the annual report that it distributes to shareholders in the United States. A description of the ways in which the Company's governance practices differ from those followed by domestic companies pursuant to Nasdaq standards are as follows:

* *Shareholder Meeting Annual Requirement*: Nasdaq Stock Market Rule 5620(a) ("Rule 5620(a)") requires that each company listing common stock or voting preferred stock, and their equivalents, shall hold an annual meeting of shareholders no later than one year after the end of the company's fiscal year-end. In lieu of following Rule 5620(a), the Company has elected to follow Canadian practices consistent with the requirements of the TSXV and the BCBCA. 

* *Shareholder Meeting Quorum Requirement*: Nasdaq Stock Market Rule 5620(c) ("Rule 5620(c)") requires that the minimum quorum requirement for a meeting of shareholders be 33 1/3 % of the outstanding Common Shares. In addition, Rule 5620(c) requires that an issuer listed on Nasdaq state its quorum requirement in its by-laws. In lieu of following Rule 5620(c), the Company has elected to follow Canadian practices consistent with the requirements of the TSXV and the BCBCA. 

* *Independent Nominating Committee*: Nasdaq Stock Market Rule 5605(e)(1) ("Rule 5605(e)(1)") requires having a Nominations Committee comprised solely of independent directors. In lieu of following Rule 5605(e)(1), the Company has elected to follow Canadian practices consistent with the requirements of the TSXV and the BCBCA. 

* *Independent Compensation Committee*: Nasdaq Stock Market Rule 5605(d)(2) ("Rule 5605(d)(2)") requires having a Compensation Committee comprised solely of independent directors. In lieu of following Rule 5605(d)(2), the Company has elected to follow Canadian practices consistent with the requirements of the TSXV and the BCBCA. 

* *Shareholder Approval Requirement*: Nasdaq Stock Market Rule 5635(d) ("Rule 5635(d)") requires shareholder approval prior to a transaction involving the sale or issuance of a company's common stock (or securities convertible into or exercisable for its common stock): (i) at a price below the greater of book value or market value; and (ii) which together with sales by officers, directors, or substantial stockholders, is equal to 20% or more of the company's outstanding shares of common stock or 20% or more of the voting power prior to issuance. In lieu of following Rule 5635(d), the Company has elected to follow Canadian practices consistent with the requirements of the TSXV and the BCBCA.
