Bridgetown, Barbados

Dear Sirs

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") in relation to a total of 1,073,514 Common Shares of
the Company of par value US$0.001 each (the "Common Shares") which may be issued
upon the exercise of options to acquire Common Shares granted or to be granted
under the Nabors Industries, Inc. 1992 Incentive Stock Plan and the Nabors
Industries, Inc. 1993 Key Employee Stock Plan (collectively, the "Plans").

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.

         obligation under, or action to be taken under, the Plans is required to

         the Plans in good faith for the purpose of carrying on its business and

(t)      that the issue price of the Common Shares issued pursuant to Awards
         issued under the Plans 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:


                                       4


(1)      The Company is an exempted company incorporated with limited liability
         and existing under the laws of Bermuda. The Company possesses the
         capacity to sue and be sued in its own name and is in good standing
         under the laws of Bermuda.

(2)      The Company has taken all necessary corporate action to authorise the
         delivery of the Registration Statement and the registration of the
         Shares pursuant to the Registration Statement.

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

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

(5)      The issue by the Company of the Shares will not violate:-

         (a)      any provision of any applicable law of Bermuda, nor, as far as
                  can be ascertained from public record, any regulation or order
                  of any governmental, judicial or public body or authority of
                  or in Bermuda;

         (b)      the Memorandum of Association or Bye-laws of the Company.


(6)      Based solely upon the Company Search and the Litigation Search:

         (i)      no litigation, arbitration or administrative or other
                  proceeding of or before any arbitrator or governmental
                  authority of Bermuda is pending against or affecting the
                  Company or against or affecting any of its properties, rights,
                  revenues or assets; and

         (ii)     no notice to the Registrar of Companies of the passing of a
                  resolution of members or creditors to wind up or the
                  appointment of a liquidator or receiver has been given. No
                  petition to wind up the Company or application to reorganise
                  its affairs pursuant to a Scheme of Arrangement or application
                  for the appointment of a receiver has been filed with the
                  Supreme Court.

(7)      The Company has received an assurance from the Ministry of Finance
         granting an exemption, until 28 March 2016, from the imposition of tax
         under any applicable Bermuda law computed on profits or income or
         computed on any capital asset, gain or appreciation, or any tax in the
         nature of estate duty or inheritance tax, provided that such exemption
         shall not prevent the application of any such tax or duty to such
         persons as are ordinarily resident in Bermuda


                                       5


         and shall not prevent the application of any tax payable in accordance
         with the provisions of the Land Tax Act 1967 or otherwise payable in
         relation to land in Bermuda leased to the Company. There are, subject
         as otherwise provided in this opinion, no Bermuda taxes, stamp or
         documentary taxes, duties or similar charges now due, or which could in
         the future become due, in connection with the delivery, performance of
         the Plans or the transactions contemplated thereby and the Company is
         not required by any Bermuda law or regulation to make any deductions or
         withholdings in Bermuda from any payment it may make thereunder.

RESERVATIONS

We have the following reservations:-

(a)      The term "enforceable" as used in this opinion means that there is a
         way of ensuring that each party performs an agreement or that there are
         remedies available for breach.

(b)      We express no opinion as to the availability of equitable remedies such
         as specific performance or injunctive relief, or as to any matters,
         which are within the discretion of the courts of Bermuda in respect of
         any obligations of the Company as set out in the Plans. In particular,
         we express no opinion as to the enforceability of any present or future
         waiver of any provision of law (whether substantive or procedural) or
         of any right or remedy which might otherwise be available presently or
         in the future under the Plans.

(c)      Enforcement of the obligations of the Company under the Plans may be
         limited or affected by applicable laws from time to time in effect
         relating to bankruptcy, insolvency or liquidation or any other laws or
         other legal procedures affecting generally the enforcement of
         creditors' rights.

(d)      Enforcement of the obligations of the Company may be the subject of a
         statutory limitation of the time within which such proceedings may be
         brought.

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

(f)      Where an obligation is to be performed in a jurisdiction other than
         Bermuda, the courts of Bermuda may refuse to enforce it to the extent
         that such performance would be illegal under the laws of, or contrary
         to public policy of, such other jurisdiction.


                                       6


(g)      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.

(h)      A Bermuda court may refuse to give effect to any provisions of the
         Plans in respect of costs of unsuccessful litigation brought before the
         Bermuda court or where that court has itself made an order for costs.

(i)      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;

         (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.


                                       7


(j)      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.

(k)      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.

(l)      In paragraph (1) above, the term "good standing" means that the Company
         has received a Certificate of Compliance from the Registrar of
         Companies.

(m)      Any reference to this opinion to 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 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.

(n)      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 Plans.
