                    INFORMATION TO BE INCLUDED IN THE REPORT


ITEM 7.01.  REGULATION FD DISCLOSURE

        The Registrant hereby incorporates by reference into this Item 7.01 the
summary report of the status, as of October 11, 2004, of the offshore drilling
rigs of the Registrant attached as Exhibit 99.1, which is being furnished in
accordance with Rule 101(e)(1) under Regulation FD and shall not be deemed to be
filed.

        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, include, but are
not limited to, statements regarding the current term, start and end dates and
comments concerning future contracts and availability and other aspects of the
Registrant's drilling rigs. 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. A discussion of the risk factors that could
impact these areas and the Registrant's overall business and financial
performance can be found in the Registrant's reports and other documents filed
with the Securities and Exchange Commission. These factors include, among
others, general economic and business conditions, 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 Registrant'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 the rig status report,
and the Registrant undertakes no obligation to publicly update or revise any
forward-looking statements.
