Under the terms of the agreement, shareholders of Rosetta will receive 0.542 shares of Noble for each share of Rosetta common stock owned. Based on Noble’s closing price on May 8, 2015, the day prior to the announcement, Rosetta shareholders would have received compensation valued at approximately $26.62 per share.
