EXPLANATORY NOTE

         This Amendment No. 1 to Annual Report on Form 10-K is being filed by
Noble Corporation, a Cayman Islands exempted company limited by shares
("Noble-Cayman"), as successor issuer to Noble Drilling Corporation, a Delaware
corporation ("Noble-Delaware"), pursuant to Rule 15d-5 promulgated under the
United States Securities Exchange Act of 1934. Pursuant to a corporate
reorganization (the "Reorganization") that became effective on April 30, 2002,
Noble-Delaware became an indirect, wholly owned subsidiary of Noble-Cayman. In
the merger, each person holding shares of Noble-Delaware common stock (and
related preferred stock purchase rights) immediately before the merger received
one ordinary share, par value US$.10 per share ("Ordinary Shares"), of
Noble-Cayman (and related preferred share purchase right) for each share of
Noble-Delaware common stock (and related preferred stock purchase right) held by
such person.

         This Amendment No. 1 to Annual Report on Form 10-K for the year ended
December 31, 2001 (the "2001 Form 10-K") is being filed for the following
purposes:

         (1) To file the financial statements required by Form 11-K for the
             fiscal year ended December 31, 2001 with respect to the Noble
             Drilling Corporation 401(k) Savings Plan (formerly the Noble
             Drilling Corporation Thrift Plan) as Exhibit 99.1.

         (2) To amend Item 14 of the 2001 Form 10-K to reflect the filing
             herewith of new Exhibit 99.1. Item 14 is restated as set forth
             below.

         (3) To restate in its entirety the Index to Exhibits to the 2001 Form
             10-K as set forth following the signature page, in order to reflect
             the inclusion therein, and the filing herewith, of new Exhibit
             99.1.

         Pursuant to the Reorganization, Ordinary Shares will henceforth be
issuable under the Noble Drilling Corporation 401(k) Savings Plan in lieu of
common stock of Noble-Delaware, but Noble-Delaware will continue to sponsor the
Plan. The 2001 Form 10-K is not being updated by this Amendment No. 1, except as
specifically enumerated above. All references in this Amendment No. 1 to "the
Registrant" in connection with dates preceding the Reorganization are references
to Noble-Delaware.
