ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On October 25, 2004, Nabors Industries, Inc., a Delaware corporation,
as issuer ("Nabors Delaware"), and Nabors Industries Ltd., a Bermuda exempted
company, as guarantor (the "Company"), entered into a Second Supplemental
Indenture (the "2021 Supplemental Indenture"), with J.P. Morgan Trust Company,
National Association (as successor to Bank One, N.A.), as trustee (the
"Trustee"), to the Indenture, dated as of February 5, 2001, as amended (the
"2021 Indenture"), by and among Nabors Delaware, the Company and the Trustee
with respect to Nabors Delaware's Zero Coupon Convertible Senior Debentures due
2021 (the "2021 Securities"). Nabors Delaware is a wholly owned subsidiary of
the Company.

         In addition, on October 25, 2004, Nabors Delaware, as issuer, and the
Company, as guarantor, entered into a First Supplemental Indenture with the
Trustee (together with the 2021 Supplemental Indenture, the "Supplemental
Indentures") to the Indenture, dated as of June 10, 2003 (together with the 2021
Indenture, the "Existing Indentures"), by and among Nabors Delaware, the Company
and the Trustee with respect to Nabors Delaware's Zero Coupon Senior
Exchangeable Notes due 2023 (the "2023 Securities" and together with the 2021
Securities, the "Securities").

         The Supplemental Indentures contain the following provisions and
generally have the following effects on the Existing Indentures:

     o   The Existing Indentures provided that Nabors Delaware had the right to
         elect, by written notice to holders ("Company Notice"), to pay the
         purchase price in cash or in the Company's common shares ("Common
         Shares"), or any combination of cash and Common Shares, when holders
         require Nabors Delaware to repurchase all or a portion of the
         Securities at the holder's option as provided in the Existing
         Indentures. In the Supplemental Indentures, Nabors Delaware and the
         Company covenanted and agreed for the benefit of the holders of
         Securities that in any Company Notice, Nabors Delaware will in all
         circumstances elect to pay the purchase price described above solely in
         cash.

     o   The Existing Indentures provide that upon an exchange of 2023
         Securities or conversion of 2021 Securities, Nabors Delaware has the
         right to elect, by written notice to holders, instead of delivering the
         number of Common Shares to be delivered upon such exchange or
         conversion, as the case may be, to pay such holder, in respect of all
         or a portion of such Securities, an amount of cash based on the value
         of such Common Shares determined pursuant to the Existing Indentures,
         provided that if such payment of cash is not permitted pursuant to the
         provisions of the Existing Indentures or any other agreement or
         instrument to which Nabors Delaware is a party or by which Nabors
         Delaware is bound or otherwise or an event of default under the
         respective Existing Indenture has occurred and is continuing, then
         Nabors Delaware will deliver Common Shares upon such exchange or
         conversion of such Securities (notwithstanding any notice of election
         to pay cash on such exchange or conversion). In the Supplemental


                                       2


         Indentures, Nabors Delaware and the Company covenanted and agreed for
         the benefit of the holders of Securities that the written notice
         described in the first sentence of this paragraph, will in all
         circumstances specify that Nabors Delaware will make payment solely in
         cash for all Securities submitted for exchange or conversion unless the
         Full Cash Price (as defined in the Supplemental Indentures) for a
         Security is greater than the Principal Amount (as defined in the
         Existing Indentures) thereof, in which case Nabors Delaware will (x)
         pay in cash the percentage of the Full Cash Price equal to the quotient
         obtained by dividing the Principal Amount of such Security by the Full
         Cash Price for such Security, and (y) pay the remaining portion of the
         payment for such Securities in either, at Nabors Delaware's option,
         cash or Common Shares.

     o   Deleting in their entirety provisions in the Existing Indentures that
         permitted Nabors Delaware and the Company, at Nabors Delaware or the
         Company's option, to enter into exchange or conversion arrangements
         with investment banks when Nabors Delaware calls the Securities for
         redemption.

         The Supplemental Indentures were entered into without the consent of
holders of Securities pursuant to Section 9.01(4) of each of the Existing
Indentures. Section 9.01(4) of each of the Existing Indentures permits
amendments without the consent of holders to make any change that does not
adversely affect the rights of any holder of Securities.

         The above description of the Supplemental Indentures is a summary only
and is qualified in its entirety by reference to the Supplemental Indentures
which are filed as exhibits to this Current Report on Form 8-K.
