(1)  Includes Series A Junior Participating Preferred Share Purchase Rights (the
     "Rights"). The Rights are associated with and will trade with the Ordinary
     Shares of the registrant. No additional registration fee is required with
     respect to the Rights.

(2)  Represents the number of additional Ordinary Shares of the registrant that
     may be issued in connection with the merger of Noble-Delaware and Noble
     Cayman Acquisition Corporation (the "merger"), as described in Registration
     Statement No. 333-84278, which became effective on March 22, 2002. In
     connection with the filing of that Registration Statement, 132,135,326
     Ordinary Shares of the registrant (and the related Rights) were registered
     with the Securities and Exchange Commission and a fee of $441,948 was paid.
     The registrant now anticipates that up to 134,635,326 of its Ordinary
     Shares (and related Rights) may be issued in the merger.

(3)  Reflects the market price of the common stock of Noble-Delaware to be
     exchanged for Ordinary Shares of the registrant in connection with the
     merger computed in accordance with Rule 457(c) and Rule 457(f)(1) under the
     Securities Act based upon the average of the high and low prices of the
     common stock of Noble-Delaware as reported by the New York Stock Exchange,
     Inc. on April 15, 2002, and is estimated solely to determine the
     registration fee.

    The Registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the registrant shall
file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until the Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to Section 8(a), may determine.

Purchase Rights (the "Rights")) for issuance in connection with the merger of
Noble Cayman Acquisition Corporation, an indirect, wholly owned subsidiary of
the registrant, with and into Noble Drilling Corporation (the "Merger").

number of Ordinary Shares of the registrant (and related Rights) to be issued
pursuant to the Merger is now expected not to exceed 134,635,326.
