Noble Corporation celebrates its 90th year in 2011. Very few companies, and even fewer drilling contractors, can claim this milestone. The Company's proactive style of management has guided it from a one rig operation in 1921 to one of the largest offshore drilling contractors in the world today. The Company's growth since the time of its spin-off from Noble Affiliates in 1985 has come about through a series of strategic acquisitions of offshore drilling assets and ancillary, non-capital intensive businesses around the world.

Noble is a leading offshore drilling contractor for the oil and gas industry. Noble performs, through its subsidiaries, contract drilling services with a fleet of 79 offshore drilling units (including seven ultra-deepwater rigs and six jackup drilling rigs currently under construction), located worldwide, including in the Middle East, India, the U.S. Gulf of Mexico, Mexico, the Mediterranean, the North Sea, Brazil, West Africa and Asian Pacific. Noble's shares are traded on the New York Stock Exchange under the symbol "NE".

Noble will continue to perpetuate this heritage by providing the highest quality service and performance; which its customers, employees and shareholders have come to know and expect. www.noblecorp.com
