It is expected that the common shares of Pipestone Energy (the “Pipestone Energy Shares”) will commence trading on the TSX Venture Exchange ("TSX-V") under the trading symbol "PIPE" within two to three business days following the date of this press release and the issuance of a bulletin by the TSX-V regarding completion of the Arrangement. Blackbird’s existing common share purchase warrants (“Warrants”) will continue as obligations of Pipestone Energy and will retain the trading symbol “BBI.WT”.
