The Company's common stock continues to trade on the NYSE. However, starting on May 31, 2013, the NYSE will transmit the Company's trading symbol with a ".BC" indicator until the price condition has been cured. The Company's common stock also continues to trade on the Toronto Stock Exchange under the symbol "LPR", and that listing is not affected by the receipt of the NYSE notification. In addition, the Company's U.S. Securities and Exchange Commission and Canadian securities regulatory authority reporting requirements are not affected by the receipt of the NYSE notification.
