YM has entered into a Sales Agreement, dated April 23, 2010, with Cantor Fitzgerald & Co., under which YM may, at its discretion, from time to time sell up to a maximum of 7,750,000, of its common shares through an "at-the-market" equity offering program known as a Controlled Equity Offering ("CEO"). Cantor Fitzgerald & Co. will act as sales agent for any sales made under the CEO. The common shares will be sold at market prices prevailing at the time of a sale (if any) of the common shares or at prices negotiated with Cantor Fitzgerald & Co., and, as a result, prices may vary as between purchasers and during the period of the offering. The Company is not required to sell any of the reserved shares at any time during the term of the CEO, which extends until October 16, 2011, and there are no stand-by fees for having established the arrangement. The Sales Agreement does not prohibit the Company from conducting additional financings.

The Canadian prospectus and prospectus supplement have been filed on SEDAR and the U.S. prospectus and the supplement thereto have been filed on the SEC's website (www.sec.gov). Alternatively, Cantor Fitzgerald & Co. will provide any of those documents upon request. Such requests may be made by contacting Cantor Fitzgerald & Co., Attention: Equity Capital Markets, 110 E. 59th Street, New York, NY 10022, or by calling 212-829-7122.

This press release does not and shall not constitute an offer to sell or the solicitation of an offer to buy any of the common shares, nor shall there be any sale of the common shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.
