NABORS INDUSTRIES LTD  (THE "COMPANY")


We have acted as legal counsel in Bermuda to the Company in connection with the
filing by the Company with the Securities and Exchange Commission, under the
Securities Act of 1933, as amended, of a registration statement on Form S-8
(the "Registration Statement") registering 3,500,000 Common Shares of the
Company of par value US$0.001 each (the "Common Shares") issuable pursuant to
the Nabors Industries Limited 2003 Employee Stock Plan (collectively, the
"Plan"). The Plan provides, among other things, for the discretionary grant of
Common Shares subject to restrictions and stock options as further described in
the Plan.

For the purposes of this opinion we have examined and relied upon the documents
listed, and in some cases defined, in the Schedule to this opinion (the
"Documents") together with such other documentation, as we have considered
requisite to this opinion. Unless otherwise defined herein, capitalized terms
have the meanings assigned to them in the Registration Statement.

                                                                          Page 1

         conformed, notarised, faxed or photostatic copies;

         received by electronic means is complete, intact and in conformity with
         the transmission as sent;

         accurate and complete;

(f)      that there are no provisions of the laws or regulations of any
         jurisdiction other than Bermuda which would be contravened by the Plan
         or which would have any implication in relation to the opinion
         expressed herein and that, in so far as any obligation under, or action
         to be taken under, the Plan is required to be performed or taken in any
         jurisdiction outside Bermuda such action or obligation will not be
         illegal by virtue of the laws of that jurisdiction;

                                                                          Page 2

(g)      that the records which were the subject of the Company Search were
         complete and accurate at the time of such search and disclosed all
         information which is material for the purposes of this opinion and such
         information has not since the date of the Company Search been

(h)      that the records which were the subject of the Litigation Search were
         complete and accurate at the time of such search and disclosed all
         information which is material for the purposes of this opinion and such
         information has not since the date of the Litigation Search been
         materially altered;

(i)      that the Resolutions are in full force and effect, have not been
         rescinded, either in whole or in part, and there is no matter affecting
         the authority of the Directors to effect entry by the Company into the
         Plan, or to perform their obligations under the Registration Statement
         not disclosed by the Constitutional Documents or the Resolutions, which
         would have any adverse implication in relation to the opinions
         expressed herein;

(j)      that each Director of the Company, when the Board of Directors adopted
         the Resolutions (which are the Directors' resolutions), discharged his

         with a view to the best interests of the Company;

(m)      that the approval of the issue of any Awards under the Plan are duly
         made at a duly convened and quorate meeting of the Committee in a
         manner complying with the terms of its constitution then in force
         within the authority then given to the Committee by the Board of
         Directors of the Company; and

(n)      that the issue price of the Common Shares issued pursuant to Awards
         issued under the Plan will not be less than the par value of such
         shares and the Company will have sufficient authorised share capital to
         effect the issue of such shares and will continue to hold the necessary
         consent of the Bermuda Monetary Authority.

OPINION

Based upon and subject to the foregoing and subject to the reservations set out
below and to any matters not disclosed to us, we are of the opinion that:-

(1)      The Company has taken all necessary corporate action to authorise the
         Plan and the issuance of the Common Shares.

(2)      When issued in accordance with the Resolutions and the Plan, the Common
         Shares will be duly and validly issued, fully paid, non-assessable
         shares of the Company.

RESERVATIONS:

We have the following reservations:-

(a)      We express no opinion as to any law other than Bermuda law and none of
         the


                                                                          Page 4

         opinions expressed herein relates to compliance with or matters
         governed by the laws of any jurisdiction except Bermuda. This opinion
         is limited to Bermuda law as applied by the courts of Bermuda at the
         date hereof.

(b)      Where a person is vested with a discretion or may determine a matter in
         his or its opinion, such discretion may have to be exercised reasonably
         or such an opinion may have to be based on reasonable grounds.

(c)      Searches of the Register of Companies at the office of the Registrar of
         Companies and of the Supreme Court Causes Book at the Registry of the
         Supreme Court are not conclusive and it should be noted that the
         Register of Companies and the Supreme Court Causes Book do not reveal:

         (i)      whether an application to the Supreme Court for a winding up
                  petition or for the appointment of a receiver or manager has
                  been prepared but not yet been presented or has been presented
                  but does not appear in the Causes Book at the date and time
                  the Search is concluded;

         (ii)     whether any arbitration or administrative proceedings are
                  pending or whether any proceedings are threatened, or whether
                  any arbitrator has been appointed;

         (iii)    details of matters which have been lodged for filing or
                  registration which as a matter of general practice of the
                  Registrar of Companies would have or should have been
                  disclosed on the public file but have not actually been
                  registered or to the extent that they have been registered
                  have not been disclosed or do not appear in the public records
                  at the date and time the search is concluded;


                                                                          Page 5

         (iv)     details of matters which should have been lodged for
                  registration but have not been lodged for registration at the
                  date the search is concluded; or

         (v)      whether a receiver or manager has been appointed privately
                  pursuant to the provisions of a debenture or other security,
                  unless notice of the fact has been entered in the Register of
                  Charges in accordance with the provisions of the Companies Act
                  1981.

         Furthermore, in the absence of a statutorily defined system for the
         registration of charges created by companies incorporated outside
         Bermuda ("overseas companies") over their assets located in Bermuda, it
         is not possible to determine definitively from searches of the Register
         of Charges maintained by the Registrar of Companies in respect of such
         overseas companies what charges have been registered over any of their
         assets located in Bermuda or whether any one charge has priority over
         any other charge over such assets.

(d)      In order to issue this opinion we have carried out the Company Search
         as referred to in the Schedule to this opinion and have not enquired as
         to whether there has been any change since the date and time such
         search was completed.

(e)      In order to issue this opinion we have carried out the Litigation
         Search as referred to in the Schedule to this opinion and have not
         enquired as to whether there has been any change since the date and
         time such search was completed.

(f)      Any reference in this opinion to the Common Shares being
         "non-assessable" shall mean, in relation to fully-paid shares of the
         Company and subject to any contrary provision in any agreement in
         writing between the Company and the holder of shares, that no
         shareholder shall be obliged to contribute further amounts to the
         capital of the Company, either in order to complete payment for their
         shares, to satisfy claims of creditors of the Company, or otherwise;
         and no shareholder shall


                                                                          Page 6

         be bound by an alteration of the Memorandum of Association or Bye-laws
         of the Company after the date on which he became a shareholder, if and
         so far as the alteration requires him to take, or subscribe for
         additional shares, or in any way increase his liability to contribute
         to the share capital of, or otherwise to pay money to the Company.

(g)      Bermuda law does not recognise the concept of "treasury shares" and so
         such shares will not be available to satisfy the obligations of the
         Company to issue Common Shares under the Plan.
