("PNG" or the "Company") (NYSE: PNG) in connection with their conduct related to the proposed buyout of the Company by Plains All American Pipeline, L.P. (NYSE: PAA). Under the terms of the proposed transaction, shareholders of PNG would receive 0.435 common units of Plains All American Pipeline, L.P. for each share of PNG common stock that they own.
