ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

Eugene M. Isenberg

On December 29, 2005, Nabors Industries, Inc. and Nabors Industries Ltd.
(collectively, the "Company) and Mr. Isenberg amended Mr. Isenberg's employment
agreement. The amendment eliminates Mr. Isenberg's ability to elect to receive a
cash payment from the Company for the value of his appreciated stock options
without the consent of the Compensation Committee of the Board of Directors in
the event of a change in control of the Company. The amendment was made to
eliminate the requirement to record a liability related to the affected options
as of January 1, 2006, based on the requirements of Statement of Financial
Accounting Standards (SFAS) No. 123R, "Share-Based Payment". SFAS 123R requires
that the fair value of options be recognized as a liability whenever a company
can be required under any circumstance to settle options by transferring cash or
other assets.
