OTHER EVENTS On September 26, 2005, Diamond Offshore Drilling, Inc. (the "Company") issued a press release announcing that the drilling rigs Ocean Saratoga and Ocean Star broke free from their moorings as Hurricane Rita passed west of both semisubmersibles. Both of the units and their well operations were secured and personnel were evacuated well in advance of the storm. Both rigs were tracked during the storm by onboard locator beacons. The press release reported that the Ocean Saratoga was currently grounded in approximately 35 feet of water on Vermilion block 111. The site is approximately 100 miles northwest of the rig's original location on Green Canyon block 157. The press release reported that the Ocean Star was also aground in approximately 35 feet of water on Eugene Island block 142. The site is approximately 100 miles north of the unit's original location on Green Canyon block 768. Start-up crews re-boarded the Saratoga and Star on Sunday, September 25, 2005 in order to secure the units and to further assess their condition. Initial fly-bys of other Company rigs in the path of Hurricane Rita did not indicate any significant damage, but the press release reported that the Company will not be able to make a complete assessment of the condition of all of its rigs until personnel are able to re-board the units over the next few days. Filed herewith is a copy of such press release. Statements in this report that contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, may include, but are not limited to, statements concerning the location of the Company's drilling rigs, related search efforts, condition and damage assessments, securing the rigs, damages to the Company's drilling rigs and re-boarding the rigs. Forward-looking statements include, without limitation, statements which project, indicate or imply future results and may contain words like "expect," "intend," "plan," "will," "would," "estimated" and "budgeted," among others. Such statements are inherently subject to a variety of risks and uncertainties that could cause actual results to differ materially from those anticipated or projected. These factors include, among others, potential damage to or loss of equipment and resulting loss of contracted revenue due to Hurricane Rita, as well as general economic and business conditions, changes in oil and natural gas prices, casualty losses, industry fleet capacity, changes in foreign and domestic oil and gas exploration and production activity, competition, changes in foreign, political, social and economic conditions, regulatory initiatives and compliance with governmental regulations, customer preferences and various other matters, many of which are beyond the Company's control. Given these concerns, investors and analysts should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of this report. The Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement to reflect any change in the 2 Company's expectations with regard thereto or any change in events, conditions or circumstances on which any forward-looking statement is based. A further discussion of the risk factors that could impact these areas and the Company's overall business and financial performance can be found in the Company's reports and other filings with the Securities and Exchange Commission.
