                              EXPLANATORY STATEMENT

         This post-effective amendment No. 1 to the registration statement on
Form S-8, Registration No. 333-91743 (which we refer to as this registration
statement), is being filed pursuant to Rule 414 of the Securities Act of 1933,
as amended, by Nabors Industries Ltd., a Bermuda exempted company (which we
refer to as Nabors Bermuda), which is the successor issuer to Nabors Industries,
Inc., a Delaware corporation (which we refer to as Nabors Delaware). Nabors
Bermuda became the successor issuer to Nabors Delaware following a corporate
reorganization that became effective on June 24, 2002. The reorganization was
effected through the merger of a newly formed Delaware merger subsidiary of
Nabors Bermuda with and into Nabors Delaware, with Nabors Delaware as the
surviving corporation. Pursuant to the merger, Nabors Delaware became a
wholly-owned, indirect subsidiary of Nabors Bermuda. As a result of the merger,
each share of Nabors Delaware outstanding immediately prior to the effective
time of the merger automatically converted into the right to receive a common
share of Nabors Bermuda. After completion of the merger, the shareholders of
Nabors Delaware became the shareholders of Nabors Bermuda which, together with
its subsidiaries, will continue to be engaged in the same business that Nabors
Delaware and its subsidiaries were engaged in before the merger. Pursuant to the
reorganization, common shares of Nabors Bermuda, par value $0.001 per share,
will henceforth be issuable, in lieu of common stock of Nabors Delaware under
the 1999 Pool Employee/Director Option Exchange Plan, but Nabors Delaware will
continue to maintain and sponsor such plan.

         Nabors Bermuda expressly adopts this registration statement as its own
registration statement for all purposes under the Securities Act of 1933, as
amended, and the Securities Exchange Act of 1934, as amended.

ITEM 6.    INDEMNIFICATION OF DIRECTORS AND OFFICERS.


                                       3



         Section 98 of the Companies Act 1981 of Bermuda (which we refer to as
the Bermuda Companies Act) provides generally that a Bermuda company may
indemnify its directors and officers against any liability that by virtue of
Bermuda law otherwise would be imposed on them, except in cases where such
liability arises from fraud or dishonesty of which such director or officer may
be guilty in relation to the company. Section 98 further provides that a Bermuda
company may indemnify its directors and officers against any liability incurred
by them in defending any proceedings, whether civil or criminal, in which a
judgment is awarded in their favor or in which they are acquitted or granted
relief by the Supreme Court of Bermuda in certain proceedings arising under
Section 281 of the Bermuda Companies Act.

         Bye-law 75 of our Amended and Restated Bye-Laws provides that we shall
indemnify our current or former directors or officers against all liabilities,
losses, damages or expenses incurred or suffered out of the actual or purported
execution or discharge of their duties or the exercise or purported exercise of
their powers as officers and directors. Such exemption from liability and
indemnity shall have effect to the fullest extent of applicable law, but shall
not extend in any matter which would render any such exemption void pursuant to
the Bermuda Companies Act. Bye-law 75 further states that subject to the Bermuda
Companies Act, expenses incurred in defending any civil action or criminal
action or proceeding, for which indemnification is required pursuant to Bye-law
75, shall be paid by us in advance of the final disposition of such action or
proceeding upon our receipt of an undertaking by or on behalf of the indemnified
party to repay such amount if it shall ultimately be determined that the
indemnified party is not entitled to be indemnified.

         Our directors and officers are also parties to indemnification and/or
employment agreements which provide for these and other indemnification rights
in accordance with Bermuda law. In addition, we have obtained an aggregate of
$50,000,000 of directors' and officers' insurance coverage.

ITEM 9.   UNDERTAKINGS.

         (a)     Rule 415 Offering

         The undersigned registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this registration statement:

                           (i) To include any prospectus required by Section
                  10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
                  arising after the effective date of the registration statement
                  (or the most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the registration
                  statement;

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material change to such
                  information in the registration statement; provided, however,
                  that paragraphs (1)(i) and (ii) do not apply if the
                  information required to be included in a post-effective
                  amendment by those paragraphs is contained in periodic reports
                  filed by the registrant pursuant to Section 13 or Section
                  15(d) of the Exchange Act that are incorporated by reference
                  in this registration statement.

                  (2) That, for the purpose of determining any liability under
         the Securities Act


                                       5



         of 1933, each such post-effective amendment shall be deemed to be a new
         registration statement relating to the securities offered therein, and
         the offering of such securities at that time shall be deemed to be the
         initial bona fide offering thereof.

                  (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (b)     Filings incorporating Subsequent Exchange Act Documents by
Reference

                  The undersigned registrant hereby undertakes that, for
         purposes of determining any liability under the Securities Act of 1933,
         each filing of the registrant's annual report pursuant to section 13(a)
         or section 15(d) of the Securities Exchange Act of 1934 that is
         incorporated by reference in the registration statement shall be deemed
         to be a new registration statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.

         (c)     Filing of Registration Statement on Form S-8

                  Insofar as indemnification for liabilities arising under the
         Securities Act of 1933 may be permitted to directors, officers and
         controlling persons of the registrant pursuant to the foregoing
         provisions, or otherwise, the registrant has been advised that in the
         opinion of the Securities and Exchange Commission such indemnification
         is against public policy as expressed in the Act and is, therefore,
         unenforceable. In the event that a claim for indemnification against
         such liabilities (other than the payment by the registrant of expenses
         incurred or paid by a director, officer or controlling person of the
         registrant in the successful defense of any action, suit or proceeding)
         is asserted by such director, officer or controlling person in
         connection with the securities being registered, the registrant will,
         unless in the opinion of its counsel the matter has been settled by
         controlling precedent, submit to a court of appropriate jurisdiction
         the question whether such indemnification by it is against public
         policy as expressed in the Securities Act and will be governed by the
         final adjudication of such issue.
