ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

         (c) Exhibits

             Exhibit 99.1  Noble Corporation Press Release dated April 23, 2003,
                           announcing the financial results for the quarter
                           ended March 31, 2003.

ITEM 9. REGULATION FD DISCLOSURE.

         The following information is being furnished under Item 9 and in
accordance with Securities and Exchange Commission Release No. 33-8126, under
Item 12, "Results of Operations and Financial Condition", by being presented
under Item 9.

         On April 23, 2003, the Registrant issued a press release announcing its
financial results for the quarter ended March 31, 2003. A copy of such press
release is attached as Exhibit 99.1 and will be published in the "Newsroom" area
on the Registrant's web site at http://www.noblecorp.com. Pursuant to the rules
and regulations of the Securities and Exchange Commission, the press release is
being furnished and shall not be deemed to be "filed" under the Securities
Exchange Act of 1934.

         The press release contains forward-looking statements about the
Registrant's business, financial condition and prospects. The Registrant's
actual results could differ materially from those indicated by the
forward-looking statements because of various risks and uncertainties,
including, without limitation, changes in United States tax laws, or the
enactment of new United States tax laws, that may result in the Registrant being
subject to taxation in the United States on its worldwide earnings, other
material changes in the tax laws of the United States or other countries in
which the Registrant operates which could increase its effective tax rate,
volatility in crude oil and natural gas prices, the discovery of significant
additional oil and/or gas reserves or the construction of significant oil and/or
gas delivery or storage systems that impact regional or worldwide energy
markets, potential deterioration in the demand for the drilling services of the
Registrant and resulting declining dayrates, changes in customers' drilling
programs or budgets due to factors discussed herein or due to their own internal
corporate events, the cancellation by customers of drilling contracts or letter
agreements or letters of intent for drilling contracts or their exercise of
early termination provisions generally found in the Registrant's drilling
contracts, intense competition in the drilling industry, changes in oil and gas
drilling technology or in competitors' drilling rig fleets that could make the
Registrant's drilling rigs less competitive or require major capital investment
to keep them competitive, political and economic conditions in the United States
and in international markets where the Registrant operates, acts of war or
terrorism and the aftermath of the September 11, 2001 terrorist attacks on the
United States, cost overruns or delays on shipyard repair, maintenance,
conversion or upgrade projects, adverse weather (such as hurricanes or monsoons)
and seas, operational risks (such as blowouts and fires), limitations on the
Registrant's insurance coverage, and requirements and potential liability
imposed by governmental regulation of the drilling industry (including
environmental regulation). All of the foregoing risks and uncertainties are
beyond the Registrant's ability to control, and in many cases, the Registrant
cannot predict the risks and uncertainties that could

forward-looking statements. When used in the report, the words "believes",

Registrant or its management are intended to identify forward-looking
statements.
