Other relevant factors have been and will be disclosed in the Company’s filings with the Securities and Exchange Commission (“SEC”).

The Company urges its stockholders —including participants in its equity based incentive compensation plans — and investors to read carefully the proxy statement/prospectus (and any other document that the Company or Rowan UK subsequently files with the SEC) before making any voting or investment decision about the proposed merger, because they contain important information about the Company, Rowan UK and the proposed merger and related transactions.
