                         UP TO 1,000,000 COMMON SHARES

                             NABORS INDUSTRIES LTD.

     This prospectus relates to the common shares of Nabors Industries Ltd., a
Bermuda exempted company (which we refer to as Nabors in this prospectus),
issuable upon exchange or redemption of the exchangeable shares of Nabors
Exchangeco (Canada) Inc., a Canadian corporation and an indirect subsidiary of
Nabors, which we call Exchangeco in this prospectus.

     The exchangeable shares are being issued to the former shareholders of Ryan
Energy Technologies Inc., a corporation incorporated under the laws of Alberta,
Canada (which we refer to as Ryan in this prospectus), in connection with our
acquisition of Ryan. Each exchangeable share may be exchanged for one of our
common shares, plus the aggregate amount of dividends payable and unpaid, if
any, on each such exchangeable share. In some cases, Exchangeco may redeem each
exchangeable share for one of our common shares plus the aggregate amount of
dividends payable and unpaid, if any, on each such exchangeable share. Because
our common shares offered by this prospectus will be issued in exchange for, or
upon the redemption of, the exchangeable shares, we will not receive any cash
proceeds from the issuance of our common shares upon exchange or redemption of
exchangeable shares in connection with this offering.

     We are paying all expenses of registration incurred in connection with this
offering.

     Nabors' common shares are traded on the American Stock Exchange under the
symbol "NBR." On September 5, 2002, the last reported sale price of our common
shares on that exchange was $30.95. Unless otherwise indicated, all dollar
references in this prospectus are to U.S. dollars.

     INVESTING IN NABORS' COMMON SHARES INVOLVES RISKS.   SEE "RISK FACTORS"
BEGINNING ON PAGE 5.

COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ADEQUACY OR ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                              RECENT DEVELOPMENTS

AGREEMENT TO ACQUIRE RYAN

     On August 12, 2002, we entered into an arrangement agreement to acquire
Ryan. The acquisition will become effective pursuant to a plan of arrangement
submitted for approval to the securityholders of Ryan and to the Court of
Queen's Bench of Alberta. We have agreed to pay Cdn$1.85 per Ryan common share.
The purchase price is payable, at the election of each individual Ryan
shareholder, in cash, in exchangeable shares of Exchangeco or in a combination
of cash and such exchangeable shares. The exchangeable shares will be
exchangeable for our common shares on a 1:1 basis, plus the aggregate amount of
dividends payable and unpaid, if any, on each such exchangeable share. We
anticipate that the acquisition will close on or about October 9, 2002.

     Under the terms of the arrangement, if the transaction is completed, each
holder of Ryan common shares who so elects will receive a number of exchangeable
shares for each common share equal to the exchange ratio. Each registered
shareholder will receive only a whole number of exchangeable shares, and will be
paid a cash amount by Exchangeco in lieu of any fractional entitlement. Each
exchangeable share will have economic and voting rights effectively equivalent
to one Nabors common share and will be exchangeable at any time for one Nabors
common share.

     Pursuant to the arrangement, the exchange ratio means a fraction the
numerator of which is Cdn$1.85 and the denominator of which is the weighted
average trading price of Nabors common shares on the American Stock Exchange,
converted to Canadian dollars, for the three consecutive trading days ending on
the third business day prior to the date of the Ryan shareholders meeting to
approve the plan of arrangement (currently expected to be October 8, 2002). For
these purposes, the "weighted average trading price" will be determined by
dividing the aggregate sale price of all Nabors common shares sold on the
American Stock Exchange during the three trading day period by the total number
of Nabors common shares sold. The weighted average trading price will be
converted to Canadian dollars based on the average of the noon buying rates
(expressed to the fourth decimal place) in New York City for cable transfers in
Canadian dollars as certified for customs purposes by the Federal Reserve Bank
of New York for each such trading day.

     Nabors and Ryan will issue a press release announcing the exchange ratio at
the end of the measurement period, currently anticipated to be issued after the
close of business on October 3, 2002.

     Optionholders of Ryan may exercise their options prior to the arrangement
becoming effective and elect to receive exchangeable shares, cash or a
combination thereof in respect of the Ryan common shares issued on such
exercise. Alternatively, optionholders of Ryan may surrender their options for
termination in which case they will be paid in cash at closing of the
arrangement, in respect of each such option, the greater of: (i) the positive
difference, if any, between Cdn$1.85 and the exercise price of such option for
each Ryan common share issuable on exercise of such option, and (ii) Cdn$0.10
per common share issuable on exercise of such option, subject to required
withholdings.

     As a result of the arrangement, all options to acquire Ryan common shares
that have not previously been exercised or surrendered for termination will be
terminated and each holder of such options will be paid in cash, in respect of
each such option, the greater of: (i) the positive difference, if any, between
Cdn$1.85 and the exercise price of such option for each Ryan common share
issuable on exercise of such

                                        2


option, and (ii) Cdn$0.10 per common share issuable on exercise of such option,
subject to required withholdings.

     Certain shareholders and optionholders of Ryan who own or control an
aggregate of 4,454,058 Ryan common shares and options to acquire 450,000 Ryan
common shares, which constitute approximately 21% of the outstanding common
shares of Ryan (diluted for in-the-money options), have agreed, subject to the
terms and conditions of those agreements, to vote their Ryan common shares and
options in favor of the plan of arrangement.

     Nabors may acquire the 4,454,058 Ryan common shares, discussed above, for
Cdn$1.85 each, upon the occurrence of the following events:

     - Ryan's board of directors withdrawing or adversely modifying or changing
       its recommendations or determinations related to the acquisition of Ryan,

     - Ryan's board of directors failing to reaffirm its recommendation of the
       arrangement by press statement within three business days after the
       expiration of the time period for Nabors to advise whether it will amend
       the terms of the arrangement to account for a superior proposal (which
       involves a proposal which is demonstrably superior to the arrangement
       from a financial point of view to Ryan's shareholders), and three
       business days after the public announcement or commencement of another
       acquisition proposal (which involves a proposal to acquire in any manner,
       directly or indirectly, beneficial ownership of or control or direction
       over more than 20% of the outstanding voting shares of Ryan),

     - Ryan's board of directors recommending that any of its shareholders
       deposit their shares under, vote in favour of, or otherwise accept, an
       acquisition proposal,

     - Ryan entering into an agreement, commitment or understanding with any
       person, entity or group with respect to an acquisition proposal prior to
       the closing of the acquisition, excluding permitted confidentiality
       agreements,

     - prior to the closing of the acquisition, Ryan breaching any of its
       representations, warranties, agreements or obligations in the arrangement
       agreement which breach would result in the failure to satisfy conditions
       related to the closing of the acquisition and which breach is: related to
       Ryan's agreement not to solicit other acquisitions, an intentional
       breach, not curable or not cured within 5 days of notice, and

     - the existence of an acquisition proposal being publicly announced or made
       to the shareholders of Ryan or Ryan providing notice of such acquisition
       proposal.

As a result of Nabors' ability to acquire the 4,454,058 Ryan common shares,
Nabors may be considered to have acquired ownership, control or direction over
such shares. Nabors did not previously own or exercise control or direction over
any securities of Ryan.

CORPORATE REORGANIZATION

     Effective June 24, 2002, Nabors became the successor to Nabors Delaware
following a corporate reorganization, which effectively changed the jurisdiction
of incorporation of Nabors from Delaware to Bermuda. The reorganization was
accomplished through a merger of an indirect, newly formed Delaware subsidiary
of Nabors with and into Nabors Delaware. Nabors Delaware was the surviving
company in the merger. As a result of the merger, Nabors Delaware became a
wholly-owned, indirect subsidiary of Nabors. Upon consummation of the merger,
all outstanding shares of Nabors Delaware common stock automatically converted
into the right to receive Nabors common shares, with the result that the
shareholders of Nabors Delaware on the date of the merger became the
shareholders of Nabors. Nabors and its subsidiaries continue to conduct the
businesses previously conducted by Nabors Delaware and its subsidiaries. The
reorganization has been accounted for as a reorganization of entities under
common control and accordingly, it did not result in any changes to the
consolidated amounts of assets, liabilities and stockholders' equity.

                                        3


     The Board of Nabors Delaware approved the expatriation transaction because
international activities are an important part of Nabors' current business and
they believe that international operations will continue to grow in the future.
Expansion of Nabors' international business is an important part of its current
business strategy and significant growth opportunities exist in the
international marketplace. Nabors believes that reorganizing as a Bermuda
company will allow Nabors to implement its business strategy more effectively.
In addition, Nabors believes that the reorganization should increase its access
to international capital markets and acquisition opportunities, increase its
attractiveness to non-U.S. investors, improve global cash management, improve
its global tax position and result in a more favorable corporate structure for
expansion of its current business.

     Several members of the United States Congress have introduced legislation
that, if enacted, would have the effect of eliminating the tax benefits of the
reorganization. In particular, on June 18, 2002, the Senate Finance Committee
approved legislation introduced by Senator Charles Grassley, the Ranking
Minority Member of the Senate Finance Committee, along with Senator Max Baucus,
the Chairman of the Senate Finance Committee, (S. 2119) that, for United States
federal tax purposes, would treat a foreign corporation, such as Nabors, that
undertakes a corporate expatriation transaction, such as the reorganization, as
a domestic corporation and, thus, such foreign corporation would be subject to
United States federal income tax. S. 2119 is proposed to be effective for
corporate expatriation transactions completed after March 20, 2002. In addition,
on July 11, 2002, Representative Bill Thomas, Chairman of the House Committee on
Ways and Means, introduced legislation (H.R. 5095) that is substantially similar
to S. 2119 with respect to its treatment of corporations that undertake a
corporate expatriation transaction such as the reorganization, except that (i)
it is proposed to apply to transactions completed after March 20, 2002 and
before March 21, 2005 and (ii) it would not permit shareholders to qualify for
tax-free treatment with respect to a corporate expatriation transaction such as
the reorganization. If any of the proposed legislation, including S. 2119 or
H.R. 5095, were enacted with their proposed effective dates, the tax savings
would not be realized from the reorganization.

     In addition, there has been significant, increased negative publicity and
criticism of corporate expatriation transactions from public pension funds and
other investors since the time Nabors completed its reorganization.

     In light of such events and if and when any such legislation is enacted,
Nabors will consider the effects of such legislation and will evaluate all
strategic alternatives that may be necessary or prudent in response to such
legislation.

ISSUANCE OF SENIOR NOTES BY NABORS DELAWARE AND NABORS HOLDINGS

     On August 22, 2002 Nabors Holdings 1, ULC (which we refer to as Nabors
Holdings in this prospectus), an indirect, wholly-owned subsidiary of Nabors,
issued $225 million aggregate principal amount of 4.875% senior notes due 2009
(which refer to as Nabors Holdings notes in this prospectus), fully and
unconditionally guaranteed by Nabors and Nabors Delaware, to qualified
institutional buyers under Rule 144A of the Securities Act of 1933, as amended,
of the United States (which we refer to as Rule 144A in this prospectus).
Concurrently with this offering by Nabors Holdings, Nabors Delaware issued $275
million aggregate principal amount of 5.375% senior notes due 2012 (which we
refer to as the Nabors Delaware notes in this prospectus), fully and
unconditionally guaranteed by Nabors, to qualified institutional buyers under
Rule 144A. Interest on the Nabors Holdings notes and the Nabors Delaware notes
is payable August 15 and February 15 of each year, beginning on February 15,
2003.

     Both the Nabors Holdings notes and the Nabors Delaware notes are unsecured
and are effectively junior in right of payment to any of such issuer's future
secured debt. The Nabors Holdings notes and Nabors Delaware notes will rank
equally in right of payment with any of such issuer's future unsubordinated debt
and will be senior in right of payment to any of such issuer's subordinated
debt. The guarantees of Nabors Delaware and Nabors with respect to the Nabors
Holdings notes, and the guarantee of Nabors with respect to the Nabors Delaware
notes, will be similarly unsecured and have a similar ranking to the series of
notes so guaranteed.

     Subject to certain qualifications and limitations, the indenture governing
the Nabors Holdings notes and the indenture governing the Nabors Delaware notes
limit the ability of Nabors and its subsidiaries to incur liens and to enter
into sale and lease-back transactions. In addition, such indentures limit the
ability of Nabors, Nabors Delaware and Nabors Holdings to enter into mergers,
consolidations or transfers of all or substantially all of such entity's assets
unless the successor company assumes the obligations of such entity under the
applicable indenture.

     In exchange for Nabors Holdings notes, Nabors Holdings expects to issue new
notes consisting of up to $225 million aggregate principal amount of 4.875%
senior notes due 2009 which will have been registered under the Securities Act
of 1933, as amended (which we refer to as the Nabors Holdings exchange notes in
this prospectus). The terms of the Nabors Holdings exchange notes, including the
terms of the guarantees by Nabors Delaware and Nabors, will be substantially
identical to those of the Nabors Holdings notes, except that the transfer
restrictions and registration rights relating to the Nabors Holdings notes will
not apply to the Nabors Holdings exchange notes.

     Similarly, Nabors Delaware expects to issue new notes consisting of up to
$275 million aggregate principal amount of 5.375% senior notes due 2012 which
will have been registered under the Securities Act of 1933, as amended (which we
refer to as the Nabors Delaware exchange notes in this prospectus) in exchange
for the Nabors Delaware notes. The terms of the Nabors Delaware exchange notes,
including the terms of the guarantee by Nabors, will be substantially identical
to those of the Nabors Delaware notes, except that the transfer restrictions and
registration rights relating to the Nabors Delaware notes will not apply to the
Nabors Delaware exchange notes.

                                  RISK FACTORS

     Investing in our common shares involves risk. In addition to the risk
factors described: (i) in Nabors Delaware's Annual Report on Form 10-K, for the
year ended December 31, 2001, as amended, under the heading "Item 7.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS", (ii) in our Quarterly Report on Form 10-Q, for the quarter ended
June 30, 2002, under the heading "Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" and (iii) in our Registration
Statement on Form S-4, filed with the SEC on January 2, 2002, as amended, under
the heading "RISK FACTORS," which are incorporated by reference in this
prospectus, and the other information contained or incorporated by reference in
this prospectus, you should carefully consider the risk factors described below
before making an investment decision. The risks and uncertainties described
below and incorporated by reference are not the only risks we face. Additional
risks and uncertainties not presently known to us or that we currently deem
immaterial may impair our future business operations.

THE EXCHANGE OF YOUR EXCHANGEABLE SHARES IS GENERALLY TAXABLE.

     Based on the tax laws as of the date of this prospectus, the exchange of
exchangeable shares for our common shares is generally a taxable event in Canada
and may be a taxable event in the United States. A holder's tax consequences can
vary depending on a number of factors, including the residency of the holder,
the method of the exchange and the length of time that the exchangeable shares
were held prior to the exchange. Canadian and United States federal income tax
consequences will vary depending on your particular circumstances. We strongly
urge you to consult your tax advisor as to the tax consequences of exchanging
your exchangeable shares for our common shares. See "Income Tax Considerations."

THE MARKET PRICE OF OUR COMMON SHARES MAY BE LESS THAN THE MARKET PRICE OF THE
EXCHANGEABLE SHARES.

     Our common shares are listed on the American Stock Exchange, and the
exchangeable shares are listed on the Toronto Stock Exchange. We do not intend
to list the exchangeable shares or our common shares on any other stock exchange
in Canada or in the United States. As a result, the price at which the
exchangeable shares trade is based upon the market for such shares on the
Toronto Stock Exchange, and
                                        5


the price at which our common shares trade is based upon the market for such
shares on the American Stock Exchange. Although we believe that the market price
of the exchangeable shares on the Toronto Stock Exchange and the market price of
our common shares on the American Stock Exchange should reflect essentially
equivalent values, there can be no assurance that the market price of our common
shares will be identical, or even similar, to the market price of the
exchangeable shares.

OUR COMMON SHARES WILL BE FOREIGN PROPERTY FOR CANADIAN TAX PURPOSES.

     You may be required to limit your investment in our common shares or risk
incurring penalties under the Income Tax Act (Canada) if you are:

     - a registered pension plan;

     - a registered retirement savings plan;

     - a registered retirement income fund;

     - a deferred profit sharing plan; or

     - among some other classes of tax-exempt person.

     So long as the exchangeable shares are listed on a prescribed Canadian
stock exchange, which exchanges include the Toronto Stock Exchange, and
Exchangeco maintains a substantial presence in Canada, the exchangeable shares
will not be foreign property under the Income Tax Act (Canada). Our common
shares will, however, be foreign property for these plans or persons. These
plans or persons may have to limit their investment in our common shares or risk
incurring penalties under the Income Tax Act (Canada).

                      WHERE YOU CAN FIND MORE INFORMATION

     We file annual, quarterly and current reports, proxy statements and other
information with the SEC. Nabors Delaware previously filed such reports and
materials but is no longer required to do so following the corporate
reorganization on June 24, 2002, described under the section entitled "Recent
Developments." Nabors Delaware's previous filings pertain to Nabors because
Nabors pursuant to a reorganization became the successor entity to Nabors
Delaware. You may obtain any document we file or filed by Nabors Delaware with
the SEC at the SEC's Public Reference Room in Washington, D.C. You may obtain
information on the operation of the SEC's Public Reference Room by calling the
SEC at 1-800-SEC-0330. You can request copies of these documents, upon payment
of a duplicating fee, by writing to the SEC at its principal office at 450 Fifth
Street, N.W., Washington, D.C. 20549-1004. Our SEC filings are also accessible
through the Internet at the SEC's web site at http://www.sec.gov. In addition,
reports, proxy and information statements and other information concerning
Nabors can be inspected at the American Stock Exchange, 86 Trinity Place, New
York, New York 10006, where Nabors' common shares are listed.

                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The SEC permits us to "incorporate by reference" into this prospectus the

     We have filed with the SEC a registration statement on Form S-3 under the
Securities Act of 1933, as amended (which we refer to as the Securities Act in
this prospectus), covering the securities described in this prospectus. This
prospectus does not contain all of the information included in the registration
statement. Any statement made in this prospectus concerning the contents of any
contract, agreement or other document is only a summary of the actual contract,
agreement or other document. If we have filed any contract, agreement or other
document as an exhibit to the registration statement, you should read the
exhibit for a more complete understanding of the document or matter involved.
Each statement regarding a contract, agreement or other document is qualified in
its entirety by reference to the actual document.

                           FORWARD-LOOKING STATEMENTS

     The statements in this document and the documents incorporated by reference
that relate to matters that are not historical facts are "forward-looking
statements" within the meaning of Section 27A of the Securities Act and Section
21E of the Securities Exchange Act of 1934. When used in this document and the
documents incorporated by reference, words such as "anticipate," "believe,"
"expect," "plan," "intend," "estimate," "project," "will," "should," "could,"
"may," "predict" and similar expressions are intended to identify
forward-looking statements. Further events and actual results may differ
materially from those set forth or implied in forward-looking statements. Any
forward-looking statements, including statements regarding the intent, belief or
current expectations of Nabors or management, are not guarantees of future
performance and involve risks, uncertainties and assumptions about Nabors and
the industry in which we operate, including, among other things:

     - fluctuations in worldwide prices and demand for oil and natural gas;

     - fluctuations to levels of oil and natural gas exploration and development
       activities;

     - fluctuations in the demand for contract drilling and workover services;

     - the existence of competitors, technological changes and developments in
       the oilfield services industry;

     - the existence of operating risks inherent in the oilfield services
       industry;

     - the existence of regulatory and legislative uncertainties;
                                        7


     - outcomes of pending and future litigation;

     - the possibility of political instability, war or acts of terrorism in any
       of the countries in which we do or will do business;

     - changes in capital needs;

     - an inability to execute our business strategy; and

     - general economic conditions.

     Our businesses depend, to a large degree, on the level of spending by oil
and gas companies for exploration, development and production activities.
Therefore, a sustained increase or decrease in the price of natural gas or oil,
which could have a material impact on exploration and production activities,
could also materially affect our financial position, results of operations and
cash flows.

     All forward-looking statements in this prospectus are based on information
available to us on the date of this prospectus. We do not intend to update or
revise any forward-looking statements that we may make in this prospectus or
other documents, reports, filings or press releases, whether as a result of new
information, future events or otherwise.

                                USE OF PROCEEDS

     Because our common shares will be issued in exchange for exchangeable
shares, we will not receive any cash proceeds upon the issuance of our common
shares upon exchange or redemption of the exchangeable shares.

                              PLAN OF DISTRIBUTION

EXCHANGEABLE SHARES

     Our common shares may be issued to you in exchange for your exchangeable
shares in the following ways:

     - You may require Exchangeco to exchange your exchangeable shares for an
       equivalent number of our common shares. We refer to this as your
       retraction rights.

     - Exchangeco may automatically redeem your exchangeable shares for our
       common shares at any time on or after April 26, 2007, or upon the
       occurrence of any of the events described under "Our Redemption Rights."
       We refer to these rights as our redemption rights.

     - Upon our liquidation or the liquidation or insolvency of Exchangeco, you
       may be required to, or may choose to, exchange your exchangeable shares
       for our common shares. We refer to these rights as your exchange rights.

     In addition, 3064297 Nova Scotia Company, an unlimited liability company
organized under the laws of Nova Scotia, Canada, and our indirect, wholly-owned
subsidiary (which we refer to as Callco in this prospectus) may exercise call
rights over your exchangeable shares as described under "Callco's Call Rights"
beginning on page 12. These call rights permit Callco to require an exchange of
your exchangeable shares for our common shares if you exercise your retraction
rights or exchange rights or in any circumstance where Exchangeco exercises its
redemption rights. We are also permitted to exercise the call right identified
below as the "change of law call right". Callco and Nabors plan to exercise
their call rights, when available, and we currently foresee no circumstances
under which Callco or Nabors would not exercise their call rights. Consequently,
we expect that you will receive our common shares through an exchange with
Callco or Nabors, as the case may be, as opposed to a redemption by Exchangeco,
of your exchangeable shares for our common shares. While the consideration
received upon an exchange with

                                        8


Callco or Nabors or a redemption by Exchangeco will be the same, the tax
consequences will be substantially different. These call rights are described
below and are respectively called the:

     - retraction call rights;

     - liquidation call rights;

     - redemption call rights; and

     - change of law call rights.

YOUR RETRACTION RIGHTS

     Subject to applicable law and Callco's retraction call right described in
this prospectus, you are entitled at any time to retract, or require Exchangeco
to redeem, any or all of your exchangeable shares and to receive an equal number
of our common shares plus the aggregate amount of dividends payable and unpaid,
if any, on each such exchangeable share. You may exercise your retraction rights
by presenting to the transfer agent for the exchangeable shares or Exchangeco:

     - a certificate or certificates representing the number of exchangeable
       shares you desire to retract;

     - any other documents as may be required to effect the retraction of such
       exchangeable shares; and

     - a duly executed retraction request:

      - specifying the number of exchangeable shares you desire to retract;

      - stating the retraction date on which you desire to have Exchangeco
        redeem your exchangeable shares, which must be between 10 and 15
        business days from the date Exchangeco receives the request; and

      - acknowledging Callco's overriding retraction call right to purchase all
        but not less than all of the retracted shares directly from you and that
        the retraction request will be deemed to be a revocable offer by you to
        sell the retracted shares to Callco in accordance with Callco's
        retraction call right on the terms and conditions described below.

     Exchangeco will promptly notify Callco upon receipt of a retraction
request. In order to exercise its retraction call right, Callco must notify
Exchangeco of its determination to do so within five business days of
Exchangeco's receipt of the retraction request. If Callco delivers the call
notice to Exchangeco within five business days, and you have not revoked your
retraction request, Exchangeco will not redeem the retracted shares and Callco
will purchase from you the retracted shares on the retraction date. If Callco
does not timely deliver the call notice and you have not revoked your retraction
request, Exchangeco will redeem the retracted shares on the retraction date. In
the event that Callco exercises its retraction call right, the closing of the
purchase and sale of the retracted shares under the retraction call right will
be deemed to occur as at the close of business on the retraction date, and no
redemption by Exchangeco of the retracted shares will take place on the
retraction date.

     You may revoke a retraction request by giving notice in writing to
Exchangeco at any time prior to the close of business on the business day
immediately preceding the retraction date, in which case the retracted shares
will neither be purchased by Callco nor be redeemed by Exchangeco. If the
retraction request is not revoked on or prior to the close of business on the
business day immediately preceding the retraction date, the retracted shares
will either be purchased by Callco or redeemed by Exchangeco. Callco or
Exchangeco, as the case may be, will then deliver or cause Exchangeco's transfer
agent to deliver the retraction price to you by mailing:

     - certificates representing the number of our common shares equal to the
       number of exchangeable shares purchased or redeemed, registered in your
       name or such other name as you may request; and

     - if applicable, a check payable to you for the aggregate amount of
       dividends payable and unpaid on each such exchangeable share,

                                        9


to the address recorded in the securities register of Exchangeco or to the
address specified in your retraction request or by holding the same for you to
pick up at the registered office of Exchangeco or the office of Exchangeco's
transfer agent as specified by Exchangeco, in each case less any amounts
required to be withheld because of applicable taxes.

     If, as a result of solvency requirements or applicable law, Exchangeco is
not permitted to redeem all of your exchangeable shares specified in the
retraction request, and provided Callco has not exercised its retraction call
right with respect to such retracted shares, Exchangeco will redeem only those
retracted shares requested by you (rounded down to a whole number of shares) as
would not be contrary to provisions of applicable law. The trustee under the
voting and exchange trust agreement, on your behalf, will require us to purchase
the retracted shares not redeemed by Exchangeco or purchased by Callco on the
retraction date or as soon as reasonably practicable after the retraction date,
under your exchange rights.

OUR REDEMPTION RIGHTS

     Subject to applicable law and Callco's redemption call rights discussed
below, on an automatic redemption date, Exchangeco will redeem all of the then
outstanding exchangeable shares in exchange for an equal number of our common
shares, plus the aggregate amount of dividends payable and unpaid, if any, on
each such exchangeable share. Notwithstanding any proposed redemption of the
exchangeable shares you may initiate, our redemption rights give us the
overriding right to acquire on an automatic redemption date all but not less
than all of the outstanding exchangeable shares in exchange for an equal number
of our common shares, plus the amount of all payable and unpaid dividends, if
any, on each such exchangeable share.

     An automatic redemption will occur upon the first to occur of:

     - April 26, 2007, at the discretion of the board of directors of
       Exchangeco;

     - the date that there are outstanding less than 1,500,000 exchangeable
       shares (other than exchangeable shares held by us and our affiliates) and
       the board of directors of Exchangeco decides to accelerate the redemption
       of the exchangeable shares prior to April 26, 2007 (Exchangeco will not
       exercise the redemption right based on the number of exchangeable shares
       outstanding prior to January 1, 2003, or if Ryan shareholders elect
       pursuant to the arrangement to receive in aggregate not less than 300,000
       exchangeable shares, prior to January 1, 2004);

     - the occurrence of any merger, amalgamation, tender offer, material sale
       of shares or similar transactions involving Nabors, or any proposal to
       carry out the same, in which case the board of directors of Exchangeco
       determines in good faith that it is not reasonably practicable to
       substantially replicate the terms and conditions of the exchangeable
       shares in connection with such transaction and that the redemption of all
       but not less than all of the exchangeable shares is necessary to enable
       the completion of such transaction in accordance with its terms;

     - the business day prior to the record date for any meeting or vote of
       Exchangeco shareholders to consider any matter in which the holders of
       exchangeable shares would be entitled to vote as Exchangeco shareholders,
       but, except as described in the bullet immediately following below,
       excluding meetings or votes regarding changes to the rights, privileges,
       restrictions or conditions of the exchangeable shares requiring the
       approval of the holders of the exchangeable shares; and

     - the business day following the day on which the holders of exchangeable
       shares fail to take the necessary action at a meeting or other vote of
       holders of exchangeable shares, if and to the extent the action is
       required, to approve or disapprove any change to, or in the rights of the
       holders of, the exchangeable shares, if the approval or disapproval of
       the change would be required to maintain the economic and legal
       equivalence of the exchangeable shares and our common shares.

     At least 45 days before an automatic redemption date (or if the automatic
redemption date occurs as a result of a Nabors control transaction, a record
date for a vote of Exchangeco shareholders or the failure

                                        10


of Exchangeco shareholders to approve a change to the exchangeable shares
described in the three immediately preceding bullet points above, on as many
days prior written notice as the board of directors of Exchangeco determines to
be reasonably practicable under the circumstances), Exchangeco shall provide you
with written notice of the proposed redemption or possible redemption of the
exchangeable shares by Exchangeco or the purchase of the exchangeable shares by
Callco under its redemption call right, as the case may be. In the case of a
possible automatic redemption date, the notice will be given contingently and
will be withdrawn if the contingency does not occur.

YOUR EXCHANGE RIGHTS

     Liquidation and Insolvency Rights with Respect to Exchangeco.  Subject to
Callco's liquidation call right described below, in the event of the
liquidation, dissolution or winding-up of Exchangeco or any other distribution
of assets of Exchangeco among its shareholders for the purpose of winding-up its
affairs, you will be entitled to receive for each exchangeable share one of our
common shares, together with all dividends payable and unpaid on such
exchangeable share, if any.

     In the event of the liquidation, dissolution or winding-up of Exchangeco or
any other proposed distribution of the assets of Exchangeco among its
shareholders for the purpose of winding-up its affairs, holders of the
exchangeable shares will have, subject to applicable law, preferential rights to
receive from Exchangeco, for each exchangeable share held, an amount equal to
the market price of our common shares on the last business day prior to the
liquidation, which amount shall be paid by the delivery to such holders of one
of our common shares for each exchangeable share held plus the aggregate amount
of dividends payable and unpaid on each such exchangeable share, if any. Upon
the occurrence of such liquidation, dissolution or winding-up, Callco will have
an overriding right to purchase all of the outstanding exchangeable shares
(other than exchangeable shares held by us and our affiliates) from the holders
of the exchangeable shares on the effective date of such liquidation,
dissolution or winding-up for a purchase price per share equal to the market
price of our common shares on the last business day prior to the liquidation
(which amount shall be paid by the delivery to such holders of one of our common
shares for each exchangeable share held), plus, to the extent it is not paid by
Exchangeco, the aggregate amount of dividends payable and unpaid, if any, on
each such exchangeable share.

     Upon, and during the continuance of, insolvency of Exchangeco, a holder of
exchangeable shares will be entitled to instruct the trustee under the voting
and exchange trust agreement to exercise the exchange rights with respect to any
or all of the exchangeable shares held by such holder, thereby requiring us to
purchase such exchangeable shares from the holder. As soon as practicable
following the occurrence of such an insolvency of Exchangeco or any event which
would, with the passage of time and/or the giving of notice, lead to insolvency
of Exchangeco, we and Exchangeco will give written notice of an insolvency or
such event to the trustee. As soon as practicable after the delivery of such
notice, the trustee will then notify each holder of exchangeable shares of such
event or potential event and will advise the holder of its rights with respect
to the insolvency exchange right. The purchase price payable by us for each
exchangeable share purchased under this right will be satisfied by the issuance
of one of our common shares plus, to the extent not paid by Exchangeco, the
aggregate amount of dividends payable and unpaid, if any, on each such
exchangeable share.

     An insolvency event will occur in respect of Exchangeco upon:

     - the institution by Exchangeco of any proceeding to be adjudicated as
       bankrupt or insolvent or to be wound up, or the consent of Exchangeco to
       the institution of bankruptcy, insolvency or winding-up proceedings
       against it;

     - the filing of a petition, answer or consent seeking dissolution or
       winding-up under any bankruptcy, insolvency or analogous laws, including
       the Companies Creditors' Arrangement Act (Canada) and the Bankruptcy and
       Insolvency Act (Canada), and Exchangeco's failure to contest in good
       faith such proceedings commenced in respect of Exchangeco within 30 days
       of becoming aware of the proceedings, or the consent by Exchangeco to the
       filing of any such petition or to the appointment of a receiver;
                                        11


     - the making by Exchangeco of a general assignment for the benefit of
       creditors, or the admission in writing by Exchangeco of its inability to
       pay its debts generally as they come due; or

     - Exchangeco not being permitted, under solvency requirements of applicable
       law, to redeem any retracted exchangeable shares in accordance with the
       exchangeable share conditions.

     Liquidation with Respect to Nabors.  In order for the holders of the
exchangeable shares to participate on a pro rata basis with the holders of our
common shares in the event of our liquidation, immediately prior to the
effective date of a liquidation event, each exchangeable share will
automatically be exchanged for an equivalent number of our common shares, plus,
to the extent not paid by Exchangeco, the aggregate amount of dividends payable
and unpaid, if any, on each such exchangeable share. Upon a holder's request and
surrender of exchangeable share certificates, duly endorsed in blank and
accompanied by such instruments of transfer as we may reasonably require, we
will deliver to such holder certificates representing an equivalent number of
our common shares plus, to the extent not paid by Exchangeco, the aggregate
amount of dividends payable and unpaid, if any, on exchangeable shares for each
exchangeable share exchanged under this exchange right.

     A liquidation event will occur in respect of Nabors upon:

     - determination by the Nabors board to institute voluntary liquidation,
       dissolution, or winding-up proceedings with respect to Nabors or to
       effect any other distribution of its assets among its shareholders for
       the purpose of winding-up its affairs, at least 60 days prior to the
       proposed effective date of such liquidation, dissolution, winding-up or
       other distribution; or

     - receipt by Nabors of notice of, or Nabors otherwise becoming aware of,
       any threatened or instituted claim, suit, petition or other proceedings
       with respect to the involuntary liquidation, dissolution or winding-up of
       Nabors or to effect any distribution of assets of Nabors among its
       shareholders for the purpose of winding-up its affairs, in each case
       where Nabors has failed to contest in good faith any such proceeding
       commenced in respect of Nabors within 30 days of becoming aware of the
       proceeding.

CALLCO'S CALL RIGHTS

     In the circumstances described below, Callco and, in the case of the change
of law call right, we will have overriding call rights to acquire your
exchangeable shares by delivering an equal number of our common shares, plus all
dividends then payable but unpaid on the exchangeable shares. DIFFERENT CANADIAN
FEDERAL INCOME TAX CONSEQUENCES MAY ARISE DEPENDING UPON WHETHER WE OR CALLCO
EXERCISE THE CALL RIGHTS OR WHETHER YOUR EXCHANGEABLE SHARES ARE REDEEMED BY
EXCHANGECO. See "Income Tax Considerations -- Canadian Federal Income Tax
Considerations." In any circumstance where Exchangeco is required to purchase
your exchangeable shares, we may cause Callco to acquire from us and deliver to
you our common shares. In addition, we and Callco will have an overriding call
right on your exchangeable shares if there are changes to Canadian tax laws
permitting you to exchange your exchangeable shares without recognizing any gain
or loss or any actual or deemed dividend in respect of such exchange. If and
when Callco or, if applicable, Nabors, acquires your exchangeable shares as a
result of exercise of the call rights, neither of them will be entitled to
exercise any of the voting rights attached to your exchangeable shares.

     Retraction Call Right.  If you request the redemption by Exchangeco of your
exchangeable shares, you will be deemed to offer your exchangeable shares to
Callco, and Callco will have an overriding retraction call right to acquire all,
but not less than all, of the exchangeable shares that you have requested
Exchangeco to redeem in exchange for an equal number of our common shares, plus
the aggregate amount of dividends payable and unpaid, if any, on each such
exchangeable share. Upon the exercise of Callco's retraction call right, you
will be obligated to transfer your exchangeable shares to Callco.

     Redemption Call Right.  Callco has an overriding redemption call right to
acquire on an automatic redemption date all, but not less than all, of the
exchangeable shares then outstanding (other than exchangeable shares held by
Nabors and its affiliates) in exchange for an equal number of our common
                                        12


shares, plus the aggregate amount of dividends payable and unpaid, if any, on
each such exchangeable share, and, upon the exercise of Callco's redemption call
right, you will be obligated to transfer your shares to Callco.

     Liquidation Call Right.  Callco will be granted an overriding liquidation
call right, in the event of and notwithstanding a proposed liquidation,
dissolution or winding-up of Exchangeco or any other distribution of the assets
of Exchangeco among its shareholders for the purpose of winding-up its affairs,
to acquire all, but not less than all, of the exchangeable shares then
outstanding (other than exchangeable shares held by Nabors and its affiliates)
in exchange for an equal number of our common shares, plus the aggregate amount
of dividends payable and unpaid, if any, on each such exchangeable share. Upon
the exercise of Callco's liquidation call right, you will be obligated to
transfer your exchangeable shares to Callco. Callco's acquisition of all of the
outstanding exchangeable shares upon the exercise of the liquidation call right
will occur on the effective date of the voluntary or involuntary liquidation,
dissolution or winding-up of Exchangeco.

     Change of Law Call Right.  We have the overriding right, in the event of
any amendment to the Income Tax Act (Canada) and other applicable Canadian
provincial income tax laws that permits holders of exchangeable shares who are
resident in Canada, hold the exchangeable shares as capital property and deal at
arm's length with us and Ryan (all for the purposes of the Income Tax Act
(Canada) and other applicable Canadian provincial income tax laws) to exchange
their exchangeable shares for our common shares on a basis that will not require
such holders to recognize any gain or loss or any actual or deemed dividend in
respect of such exchange for the purposes of the Income Tax Act (Canada) and
other applicable Canadian provincial income tax laws, to purchase (or to cause
Callco to purchase) from all but not less than all of the holders of the
exchangeable shares (other than any holder which is an affiliate of Nabors) all
but not less than all of the exchangeable shares held by each such holder upon
payment by Nabors or Callco, as the case may be, of an amount per share equal to
the exchangeable share price applicable on the last business day prior to the
date on which Nabors or Callco intends to purchase such shares. Payment of the
exchangeable share price will be fully satisfied by the delivery for each
exchangeable share of one of our common shares plus the aggregate amount of
dividends payable and unpaid, if any, on each such exchangeable share.

     To exercise the foregoing right, Nabors or Callco must notify the transfer
agent for the exchangeable shares of its intention to exercise such right at
least 45 days before the date on which Nabors or Callco intends to acquire the
exchangeable shares. Upon the exercise of this right, holders will be obligated
to sell their exchangeable shares to Nabors or Callco, as the case may be.

     If we or Callco exercise one or more of our call rights, Nabors or Callco
will issue or deliver our common shares to you and will become the holder of
your exchangeable shares. If and when Callco or, if applicable, Nabors, acquires
your exchangeable shares under the call rights, neither of them will be entitled
to exercise any of the voting rights attached to your exchangeable shares. If we
or Callco decline to exercise our respective call rights when available, we will
be required to issue our common shares as Exchangeco directs, including to
Exchangeco, which will, in turn, transfer our common shares to you in
consideration for the return and cancellation of your exchangeable shares. In
the event we or Callco do not exercise our call rights when applicable and
instead deliver our common shares as Exchangeco directs, you would receive the
same consideration, but the Canadian tax consequences will be substantially
different. See "Income Tax Considerations -- Canadian Federal Income Tax
Considerations." However, we anticipate that we or Callco will exercise our call
rights, when available, and currently foresee no circumstances under which we or
Callco would not exercise our call rights. In addition, we do not anticipate any
restriction or limitation on the number of exchangeable shares we or Callco
would acquire upon the exercise of our call rights.

WITHHOLDING RIGHTS

     Each of Nabors, Callco, Exchangeco, Exchangeco's transfer agent and the
trustee will be entitled to deduct and withhold from any dividend or other
consideration otherwise payable to any holder of

                                        13


exchangeable shares or our common shares such amounts as each of Nabors, Callco,
Exchangeco, Exchangeco's transfer agent or the trustee is required to deduct and
withhold with respect to such payment under the Income Tax Act (Canada), the
United States Internal Revenue Code of 1986, as amended (the "Code"), or any
provision of federal, provincial, state, local or foreign tax law. To the extent
that amounts are so withheld, such withheld amounts will be treated for all
purposes as having been paid to the holder of the exchangeable shares or our
common shares, as the case may be, in respect of which the deduction and
withholding was made, provided that the withheld amounts are actually remitted
to the appropriate taxing authority. To the extent that the amount required to
be deducted or withheld from any payment to a holder exceeds the cash portion of
the dividend or other consideration otherwise payable to the holder, Nabors,
Callco, Exchangeco, Exchangeco's transfer agent and the trustee are authorized
to sell or otherwise dispose of the portion of the consideration necessary to
provide sufficient funds to Nabors, Callco, Exchangeco, Exchangeco's transfer
agent or the trustee, as the case may be, to enable it to comply with the
deduction or withholding requirement and Nabors, Callco, Exchangeco,
Exchangeco's transfer agent or the trustee, as the case may be, will notify the
holder and remit to the holder any unapplied balance of the net proceeds of such
sale.

                        DESCRIPTION OF OUR SHARE CAPITAL

     Our authorized share capital consists of 425,000,000 shares of capital
stock of which 400,000,000 are common shares, par value $0.001 per share, and
25,000,000 are preferred shares, par value $0.001 per share. The following
summary is qualified in its entirety by the provisions of Nabors' Memorandum of
Association, dated December 10, 2001 and Nabors' Amended and Restated Bye-Laws,
which are both publicly available. See "Where You Can Find More Information." As
of August 31, 2002, there were 144,459,268 Nabors common shares outstanding and
one Nabors special voting preferred share, par value $0.001 per share,
outstanding. No other shares of any class or series were outstanding as of
August 31, 2002.

COMMON SHARES

     Holders of our common shares are entitled to one vote on any question to be
decided on a show of hands and one vote per share on a poll on all matters
submitted to a vote of the shareholders of Nabors. Except as specifically
provided in Nabors' bye-laws or in The Companies Act 1981 (Bermuda), as amended
(which we refer to as the Companies Act in this prospectus), any action to be
taken by shareholders at any meeting at which a quorum is in attendance shall be
decided by a majority of the issued shares present in person or represented by
proxy and entitled to vote. There are no limitations imposed by Bermuda law or
Nabors' bye-laws on the right of shareholders who are not Bermuda residents to
hold or to vote their Nabors common shares.

     Our bye-laws do not provide for cumulative voting. A special meeting of
shareholders may be called by Nabors' board of directors or as otherwise
provided by the Companies Act and applicable law. Any action, except the removal
of auditors and directors, required or permitted to be taken at any annual or
special meeting of shareholders may be taken by written consent if the consent
is signed by each shareholder, or their proxy, entitled to vote on the matter.

     Holders of Nabors common shares do not have a preemptive or preferential
right to purchase any other securities of Nabors. Nabors' common shares have no
sinking fund provision.

Exchange for our common shares was $30.95 per share.

DIVIDEND POLICY

     We have never declared or paid any cash dividends on our common shares.
Nabors Delaware last paid a cash dividend in 1982. We do not anticipate paying
any cash dividends on our common shares in the foreseeable future.

PREFERRED SHARES

     The board of directors of Nabors is authorized, without further shareholder
action, to issue from time to time up to 25,000,000 preferred shares in one or
more classes or series, and fix for each such class or series such voting power,
full or limited, or no voting power, and such designations, preferences and
relative, participating, optional or other special rights and such
qualifications, limitations or restrictions thereof, as are provided in the
resolutions adopted by the board of directors providing for the issuance of such
class or series. The Nabors board of directors in authorizing such class or
series may provide that any such class or series may be:

     - subject to redemption at the option of the company or the holders, or
       both, at such time or times and at such price or prices;

     - entitled to receive dividends (which may be cumulative or non-cumulative)
       at such rates, on such conditions, and at such times, and payable in
       preference to, or in relation to, the dividends payable on any other
       class or classes or any other series;

     - entitled to such rights upon the dissolution of, or upon any distribution
       of the assets of, Nabors; or

                                        15


     - convertible into, or exchangeable for, shares of any other class or
       classes of shares, or of any other series of the same or any other class
       or classes of shares, of Nabors at such price or prices or at such rates
       of exchange and with such adjustments;

in each case, as set forth in the resolutions authorizing the class or series of
preferred shares.

     A series of preferred shares, consisting of one share, has been designated
as a special voting preferred share, having a par value of $0.001 per share and
a liquidation preference of $0.01. The special voting preferred share has been
issued to Computershare Trust Company of Canada, as trustee under a voting and
exchange trust agreement among us, Exchangeco and such trustee. Except as
otherwise required by law, our memorandum of association or our bye-laws, the
one special voting preferred share will possess a number of votes for the
election of directors and on all other matters submitted to a vote of our
shareholders equal to the number of outstanding exchangeable shares from time to
time not owned by us or any entity controlled by us. The holders of our common
shares and the holder of the special voting preferred share will vote together
as a single class on all matters on which holders of our common shares are
eligible to vote. In the event of our liquidation, dissolution or winding-up,
all outstanding exchangeable shares will automatically be exchanged for shares
of our common shares, and the holder of the special voting preferred share will
not be entitled to receive any assets available for distribution to our
shareholders (other than the $.01 liquidation preference). The holder of the
special voting preferred share will not be entitled to receive dividends. At
such time as the one special voting preferred share has no votes attached to it
because there are no exchangeable shares outstanding not owned by us or an
entity controlled by us, the special voting preferred share will be canceled.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for Nabors' common shares is EquiServe.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND
BYE-LAWS

     Nabors' bye-laws have provisions that could have an anti-takeover effect.
In addition, Nabors' bye-laws include an "advance notice" provision which places
time limitations on shareholders' nominations of directors and submission of
proposals for consideration at an annual general meeting. These provisions are
intended to enhance the likelihood of continuity and stability in the
composition of the board of directors and in the policies formulated by the
board of directors and to encourage negotiations with the board of directors in
transactions that may involve an actual or potential change of control of
Nabors.

     The bye-laws provide that Nabors' board of directors will be divided into
three classes serving staggered three-year terms. Directors can be removed from
office prior to the expiration of their term only for cause by the affirmative
vote of the holders of a majority of the voting power of Nabors on the relevant
record date. The board of directors does not have the power to remove directors.
As long as a quorum of directors remains and is present, vacancies on the board
of directors may be filled by a majority vote of the remaining directors. Any
general meeting can authorize the board of directors to fill any vacancy left
unfilled at a general meeting. Each of these provisions can delay a shareholder
from obtaining majority representation on the board of directors.

     The bye-laws also provide that the board of directors will consist of not
less than five nor more than eighteen persons, the exact number to be set from
time to time by the affirmative vote of a majority of the directors then in
office. Accordingly, the board of directors, and not the shareholders, has the
authority to determine the number of directors and could delay any shareholder
from obtaining majority representation on the board of directors by enlarging
the board of directors and filling the new vacancies with its own nominees.

     The bye-laws of Nabors provide that at any annual general meeting, only
such business shall be conducted as shall have been brought before the meeting
by or at the direction of the board of directors, by any shareholder who
complies with certain procedures set forth in the bye-laws or by any shareholder
pursuant to the valid exercise of the power granted under the Companies Act.

                                        16


     For business to be properly brought before an annual general meeting by a
shareholder in accordance with the terms of the bye-laws the shareholder must
have given timely notice thereof in proper written form to the Secretary of
Nabors and satisfied all requirements under applicable rules promulgated by the
SEC. To be timely for consideration at the annual general meeting, a
shareholder's notice must be received by the Secretary at Nabors' principal
executive offices and its registered office in Bermuda not less than 60 days nor
more than 90 days prior to the anniversary date of the immediately preceding
annual general meeting, provided that in the event that the annual general
meeting is called for a date that is not within 30 days before or after such
anniversary date, not later than the 10th day following the day on which such
notice of the date of the annual general meeting was mailed or public disclosure
of the date of the annual general meeting was made, whichever occurs first. In
order for a shareholder to nominate directors in connection with an annual
general meeting of shareholders, a shareholder's notice of his intention to make
such nominations must be received in proper written form as specified in the
bye-laws of Nabors by the Secretary of Nabors within the time limits described
above.

     In addition, the Companies Act provides for a mechanism by which 100
shareholders acting together or shareholders holding at least 5% of the voting
power of a Bermuda company may properly propose a resolution for consideration
at a general meeting of the company.

     Subject to the terms of any other class of shares in issue, any action
required or permitted to be taken by the holders of Nabors' common shares must
be taken at a duly called annual or special general meeting of shareholders
unless taken by written consent of all holders of common shares. Under the
bye-laws, special general meetings may be called at any time by the board of
directors or when requisitioned by shareholders pursuant to the provisions of
the Companies Act. The Companies Act currently permits shareholders holding 10%
of the shares of a company entitled to vote at general meeting to requisition a
special general meeting.

     The board of directors is authorized, without obtaining any vote or consent
of the holders of any class or series of shares unless expressly provided by the
terms of issue of a class or series, to from time to time issue any authorized
and unissued shares on such terms and conditions as it may determine. For
example, the board of directors could authorize the issuance of preferred shares
with terms and conditions that could discourage a takeover or other transaction
that holders of some or a majority of the Nabors common shares might believe to
be in their best interests or in which holders might receive a premium for their
shares over the then market price of the shares.

                           INCOME TAX CONSIDERATIONS

                   CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

     In the opinion of Stikeman Elliott, our Canadian counsel, the following is
a fair and accurate summary of the material Canadian federal income tax
considerations generally applicable under the Income Tax Act (Canada) (the
"Canadian Income Tax Act") if you will hold exchangeable shares or acquire our
common shares on the exchange of exchangeable shares and if, for purposes of the
Canadian Income Tax Act, you deal with us at arm's length and will hold your
exchangeable shares and our common shares as capital property. This discussion
does not apply to you if you are a "financial institution", as defined in the
Canadian Income Tax Act for the purposes of the mark-to-market provisions
thereof.

     The exchangeable shares and our common shares will generally be considered
to be capital property to you unless such shares are held by you in the course
of carrying on a business of buying and selling securities or such shares are
acquired by you in a transaction considered to be an adventure in the nature of
trade. If you are a resident of Canada and the exchangeable shares might not
otherwise qualify as capital property, you may be entitled to obtain this
qualification by making the irrevocable election provided under subsection 39(4)
of the Canadian Income Tax Act. If you will not hold your exchangeable shares or
our common shares as capital property, you should consult your own tax advisors
for information and advice having regard to your particular circumstances.

                                        17


     This summary is based on the current provisions of the Canadian Income Tax
Act and regulations thereunder, the current provisions of the Convention Between
the United States of America and Canada with Respect to Taxes on Income and on
Capital, signed September 26, 1980, as amended, (the "Canada-U.S. Tax
Convention") and our counsel's understanding of the current published
administrative practices of the Canada Customs and Revenue Agency (the "CCRA").
This summary takes into account all specific proposals to amend the Canadian
Income Tax Act and regulations that have been publicly announced by the Minister
of Finance (Canada) prior to the date hereof and assumes that all of these
proposed amendments will be enacted in their present form. No assurances can be
given that any proposed amendments will be enacted in the form proposed, if at
all. Except for the foregoing, this summary does not take into account or
anticipate any changes in law, whether by legislative, administrative or
judicial decision or action, nor does it take into account provincial,
territorial or foreign income tax legislation or considerations, which may
differ from the Canadian federal income tax considerations described below. No
advance income tax ruling has been sought or obtained from the CCRA to confirm
the tax consequences of any of the transactions relating to the exchangeable
shares or the acquisition of our common shares on the exchange of exchangeable
shares.

     For purposes of the Canadian Income Tax Act, all amounts otherwise
denominated in United States dollars relating to the acquisition, holding or
disposition of our common shares, including dividends, adjusted cost base
amounts and proceeds of disposition, must be converted into Canadian dollars
based on the prevailing United States dollar exchange rate generally at the time
these amounts arise.

THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND SHOULD
NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO YOU. THEREFORE, YOU ARE
URGED TO CONSULT YOUR OWN TAX ADVISORS WITH RESPECT TO YOUR PARTICULAR
CIRCUMSTANCES.

SHAREHOLDERS RESIDENT IN CANADA

     The following portion of this summary will apply to you only if, for the
purposes of the Canadian Income Tax Act and any applicable income tax treaty or
convention, you are resident or deemed to be resident in Canada at all relevant
times. This summary does not apply to you if we are or will be a "foreign
affiliate" of you as defined in the Canadian Income Tax Act.

  REDEMPTION OF EXCHANGEABLE SHARES

     On a redemption (including a retraction) of your exchangeable shares by
Exchangeco, you will be deemed to have received a dividend equal to the amount,
if any, by which the redemption proceeds exceed the "paid-up capital" of the
exchangeable shares so redeemed. The "paid-up capital" of an exchangeable share
will be equal to the aggregate paid-up capital of all of the exchangeable shares
divided by the number of exchangeable shares outstanding. The aggregate paid-up
capital of all of the exchangeable shares will generally be equal to the
aggregate consideration for which the exchangeable shares were issued (provided
that amount was added to the stated capital account maintained for the
exchangeable shares under the relevant corporate law), less an amount to be
determined based upon the Canadian tax elections that are (or were) filed by
former shareholders of Ryan and Enserco Energy Services Company Inc. ("Enserco")
who elected to exchange their Ryan or Enserco shares, as the case may be, for
exchangeable shares under the applicable arrangement and who are or were
permitted under the terms of the applicable arrangement to, and do, file such
Canadian tax elections. For these purposes, the redemption proceeds will be the
fair market value of our common shares received from Exchangeco at the time of
the redemption plus the amount, if any, of all payable and unpaid dividends on
the exchangeable shares paid on the redemption. The taxation of dividends
received or deemed to be received on the exchangeable shares is described below.
We anticipate that we or Callco, as the case may be, will exercise our call
rights, when available, and currently foresee no circumstances under which
exchangeable shares would be redeemed by Exchangeco.

                                        18


     On a redemption (including a retraction) of your exchangeable shares, you
will also be considered to have disposed of your exchangeable shares, but the
amount of the deemed dividend, described above, will be excluded in computing
your proceeds of disposition for purposes of computing any capital gain or
capital loss arising on the disposition. If you are a corporation, in some
circumstances, the amount of any such deemed dividend may be treated as proceeds
of disposition and not as a dividend. The taxation of capital gains and capital
losses is described below.

  EXCHANGE OF EXCHANGEABLE SHARES WITH US

     On an exchange of your exchangeable shares with us or Callco for our common
shares, you will generally realize a capital gain (or a capital loss) equal to
the amount by which the proceeds of disposition of your exchangeable shares, net
of any reasonable costs of disposition, exceed (or are less than) the adjusted
cost base to you of the exchangeable shares immediately before the exchange. For
these purposes, the proceeds of disposition will be the fair market value at the
time of the exchange of our common shares which you receive. The taxation of
capital gains and capital losses is described below. Any amount received by you
as part of the exchange that is in lieu of or in satisfaction of dividends that
are payable but not paid on the exchangeable shares will be treated as a
dividend rather than as proceeds of disposition. The taxation of dividends
received or deemed to be received on the exchangeable shares is discussed below.

  DIVIDENDS ON EXCHANGEABLE SHARES

     If you are an individual, dividends received or deemed to be received on
the exchangeable shares will be included in computing your income, and will be
subject to the gross-up and dividend tax credit rules normally applicable to
taxable dividends received from a corporation resident in Canada.

     Subject to the discussion below regarding our status as a "specified
financial institution" for the purposes of the Canadian Income Tax Act, if you
are a corporation other than a "specified financial institution," as defined in
the Canadian Income Tax Act, dividends received or deemed to be received on the
exchangeable shares normally will be included in your income and be deductible
in computing your taxable income.

     If you are a "specified financial institution", as defined in the Canadian
Income Tax Act, a dividend received on the exchangeable shares will be
deductible in computing your taxable income only if:

          1. you did not acquire the exchangeable shares in the ordinary course
     of carrying on your business; or

          2. at the time the dividend is received, the exchangeable shares are
     listed on a prescribed stock exchange in Canada (which currently includes
     the TSX) and you, either alone or together with persons with whom you do
     not deal at arm's length, do not receive (and are not deemed to receive)
     dividends in respect of more than 10% of the issued and outstanding
     exchangeable shares.

     If you are a specified financial institution, you should consult your own
tax advisors.

     We have been advised by our counsel (based in part on representations made
by us as to certain factual matters) that we currently qualify as a "specified
financial institution" for the purposes of the Canadian Income Tax Act. As a
consequence, and for so long as we continue to so qualify, if you are a
corporation (including a "specified financial institution" as defined in the
Canadian Income Tax Act), dividends received or deemed to be received on the
exchangeable shares may not be deductible in computing your taxable income
unless, at the time such dividends or deemed dividends are received, the
exchangeable shares are listed on a prescribed stock exchange (which includes
the TSX), we are "related" to Exchangeco for the purposes of the Canadian Income
Tax Act (which we are now and anticipate that we will continue to be), and you,
either alone or together with persons with whom you do not deal at arm's length
or trusts or partnerships of which you or any such non-arm's length person is a
beneficiary or member, receive dividends in respect of not more than 10 percent
of the issued and outstanding exchangeable shares.
                                        19


     If you are a "private corporation," as defined in the Canadian Income Tax
Act, or any other corporation resident in Canada and controlled or deemed to be
controlled by or for the benefit of an individual or a related group of
individuals, you may be liable under Part IV of the Canadian Income Tax Act to
pay a refundable tax of 33 1/3 percent of any dividends received or deemed to be
received on your exchangeable shares to the extent that these dividends are
deductible in computing your taxable income.

     If you are throughout the relevant taxation year a "Canadian-controlled
private corporation," as defined in the Canadian Income Tax Act, you may be
liable to pay an additional refundable tax of 6 2/3 percent of your "aggregate
investment income" for the year which will include dividends or deemed dividends
on the exchangeable shares that are not deductible in computing taxable income.

     If there is non-resident withholding tax on any dividends you receive on
exchangeable shares, you will generally be eligible for foreign tax credit or
deduction treatment where applicable under the Canadian Income Tax Act.

     If you are a corporation, the amount of any capital loss realized on a
disposition or deemed disposition of exchangeable shares may be reduced by the
amount of any dividends received or deemed to have been received by you on the
exchangeable shares to the extent and under circumstances prescribed by the
Canadian Income Tax Act. Similar rules may apply where you are a corporation and
a member of a partnership or a beneficiary of a trust that owns these shares.

  ACQUISITION AND DISPOSITION OF OUR COMMON SHARES

     The cost of our common shares received on a retraction, redemption or
exchange of exchangeable shares will be equal to the fair market value of such
common shares at the time of that event, and will be averaged with the adjusted
cost base of any other of our common shares held by you at that time as capital
property. A disposition or deemed disposition of our common shares by you will
generally result in the realization of a capital gain (or a capital loss) equal
to the amount by which the proceeds of disposition, net of any reasonable costs
of disposition, exceed (or are less than) the adjusted cost base to you of these
shares immediately before the disposition. The taxation of capital gains and
capital losses is described below.

  DIVIDENDS ON OUR COMMON SHARES

     Dividends on our common shares will be included in your income for the
purposes of the Canadian Income Tax Act. If you are an individual, these
dividends will not be subject to the gross-up and dividend tax credit rules in
the Canadian Income Tax Act applicable to dividends received from corporations
resident in Canada. If you are a corporation, you will be required to include
these dividends in computing your income and generally will not be entitled to
deduct the amount of these dividends in computing your taxable income.

     If you are throughout the relevant taxation year a "Canadian-controlled
private corporation," as defined in the Canadian Income Tax Act, you may be
liable to pay an additional refundable tax of 6 2/3 percent of your "aggregate
investment income" for the year which will include these dividends.

     If there is non-resident withholding tax on any dividends you receive on
our common shares, you will generally be eligible for foreign tax credit or
deduction treatment where applicable under the Canadian Income Tax Act.

  TAXATION OF CAPITAL GAINS AND CAPITAL LOSSES

     One-half of any capital gain realized on a disposition or deemed
disposition of exchangeable shares or our common shares must be included in your
income for the year of the disposition. You generally may be able to deduct
one-half of any capital losses against one-half of any capital gains realized in
the year of the disposition. Any capital losses in excess of capital gains in
the year of the disposition may generally be carried back and deducted against
net capital gains (capital gains less capital losses) in any of the three
taxation years immediately preceding, or carried forward and deducted against
net capital gains in any
                                        20


taxation year following, the year of disposition, to the extent and in the
circumstances prescribed in the Canadian Income Tax Act.

     If you are an individual or trust, other than certain trusts, capital gains
realized by you may give rise to alternative minimum tax under the Canadian
Income Tax Act.

     If you are throughout the relevant taxation year a "Canadian-controlled
private corporation," as defined in the Canadian Income Tax Act, you may be
liable to pay an additional refundable tax of 6 2/3 percent of your "aggregate
investment income" for the year which will include an amount in respect of
taxable capital gains.

  FOREIGN PROPERTY INFORMATION REPORTING

     With some exceptions, any taxpayer resident in Canada during a year is a
"specified Canadian entity," as defined in the Canadian Income Tax Act. If you
are a specified Canadian entity for a taxation year or fiscal period and the
total cost amount of "specified foreign property," which would include our
common shares and the exchangeable shares, at any time in the year or fiscal
period exceeds Cdn.$100,000, you will be required to file an information return
for the year or period disclosing prescribed information, your cost amount, any
dividends received in the year, and any gains or losses realized in the year, in
respect of the specified foreign property. You should consult your own advisors
about whether you must comply with these rules with respect to the ownership of
our common shares or the exchangeable shares.

  FOREIGN INVESTMENT ENTITY DRAFT LEGISLATION

     On August 2, 2001, the Canadian Minister of Finance released draft
legislation to amend the Canadian Income Tax Act to implement a proposal
concerning the taxation of certain holdings in "foreign investment entities."
Generally, a non-resident corporation will be a "foreign investment entity" for
the purposes of these rules as at any time in a particular taxation year unless
at the end of the taxation year either (i) the carrying value of the
corporation's investment properties is not greater than one-half of the carrying
value of all of its properties, or (ii) the corporation's principal business is
not an investment business. Detailed rules are proposed in respect of each of
these tests. We have been advised by our counsel (based in part on
representations made by us as to certain factual matters) that although no
assurances can be given in this regard, it appears reasonable to conclude that
we meet and will continue to meet one or both of these exceptions. Accordingly,
while a definitive opinion cannot be given, it is reasonable to expect that we
will not be considered to be a foreign investment entity and that the proposed
rules will not apply to an investment in exchangeable shares or in common shares
of Nabors.

     If Nabors is or were to become a "foreign investment entity," a Canadian
resident who holds exchangeable shares or Nabors common shares could, subject to
certain exceptions, be required to take into account in computing income, on an
annual basis, certain amounts in respect of the income of Nabors or the value of
the common shares of Nabors.

     On December 17, 2001, the Canadian Minister of Finance announced that the
proposed new rules would generally apply for taxation years beginning after
2002. However, the proposed rules have not yet been enacted and are subject to
further amendment. Accordingly, you should consult your own tax advisor
concerning these rules.

SHAREHOLDERS NOT RESIDENT IN CANADA

     The following portion of this summary will apply to you only if, for
purposes of the Canadian Income Tax Act and any applicable tax treaty or
convention, you will not be resident or deemed to be resident in Canada at any
time while you hold exchangeable shares or our common shares, and will not use
or hold the exchangeable shares or our common shares in, or in the course of,
carrying on a business (including an insurance business) in Canada and, except
as specifically discussed below, if those shares do not constitute "taxable
Canadian property" to you as defined in the Canadian Income Tax Act.

                                        21


     The exchangeable shares will generally not be taxable Canadian property to
you at a particular time provided that these shares are listed on a prescribed
stock exchange (which includes the TSX) and you, or persons with whom you do not
deal at arm's length, or you together with such persons have not owned (or had
under option) 25 percent or more of the issued shares of any class or series of
the capital stock of Exchangeco at any time within five years preceding the
particular time. Our common shares will generally not constitute taxable
Canadian property to you.

     Provided the exchangeable shares or our common shares are not taxable
Canadian property to you, you will not be subject to tax under the Canadian
Income Tax Act on the exchange of exchangeable shares for our common shares
(except to the extent the exchange gives rise to a deemed dividend as discussed
below), or on the sale or other disposition of exchangeable shares or our common
shares.

     Dividends paid or deemed to be paid on the exchangeable shares will be
subject to non-resident withholding tax under the Canadian Income Tax Act at the
rate of 25 percent, although this rate may be reduced under the provisions of an
applicable income tax treaty or convention. For example, under the Canada-U.S.
Tax Convention, the rate of non-resident withholding tax is generally reduced to
15 percent in respect of dividends paid to a person who is the beneficial owner
thereof and who is resident in the United States for purposes of the convention.

     A holder whose exchangeable shares are redeemed by Exchangeco (either under
redemption rights or pursuant to retraction rights) will be deemed to receive a
dividend equal to the amount, if any, by which the redemption proceeds exceed
the "paid-up capital," for the purposes of the Canadian Income Tax Act, of the
exchangeable shares at the time the exchangeable shares are redeemed. For these
purposes, the redemption proceeds will be the fair market value of our common
shares received from Exchangeco at the time of the redemption plus the amount,
if any, of all payable and unpaid dividends on the exchangeable shares paid on
the redemption. Any deemed dividend will be subject to non-resident withholding
tax as described in the preceding paragraph. However, we anticipate that we or
Callco, as the case may be, will exercise our call rights, when available, and
currently foresee no circumstances under which exchangeable shares would be
redeemed by Exchangeco.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     In the opinion of Skadden, Arps, Slate, Meagher & Flom LLP, the following
general discussion constitutes a fair and accurate summary of the anticipated
material United States federal income tax consequences of the ownership and
disposition of exchangeable shares that may be relevant to holders generally.
This discussion is based on the Code, United States Treasury regulations
promulgated thereunder, and judicial and administrative interpretations thereof,
in each case as in effect and available as of the date of this prospectus. These
income tax laws, regulations and interpretations, however, may change at any
time, and any change could be retroactive. It should be noted that legislation
has been introduced which, if enacted in its present form, could materially
change the discussion set forth below. Moreover, the United States Treasury
Department is currently studying transactions such as the reorganization and, as
a result, changes in these income tax laws, regulations, and interpretations may
occur, possibly with retroactive effect, which could affect the discussion set
forth below. These income tax laws and regulations are also subject to various
interpretations, and the IRS or the United States courts could later disagree
with the explanations or conclusions contained in this summary.

     No statutory, judicial or administrative authority exists that directly
addresses the United States federal income tax consequences of instruments
comparable to the exchangeable shares together with the associated ancillary
rights and call rights. Consequently, the United States federal income tax
treatment of the ownership of exchangeable shares and the exchange of
exchangeable shares for shares of Nabors common shares is not certain. No
advance ruling has been sought or obtained from the IRS regarding the tax
consequence of any of the transactions described herein and there can be no
assurance that the IRS would not challenge the conclusions contained in the
discussion below, or, if challenged, that a court would not agree with the IRS.

                                        22


     As used herein, a "United States Holder" is a beneficial owner of
exchangeable shares that, for United States federal income tax purposes, is: (1)
a citizen or resident of the United States, (2) a corporation (including for
this purpose any entity treated as a corporation for United States federal
income tax purposes) or partnership created or organized in or under the laws of
the United States, or of any political subdivision thereof, (3) an estate or
other entity the income of which is includible in its gross income for United
States federal income tax purposes without regard to its source or (4) a trust
if (A) a court within the United States is able to exercise primary supervision
over the administration of such trust and one or more United States persons have
the authority to control all substantial decisions of the trust or (B) the trust
has a valid election in effect under the applicable United States Treasury
regulations to be treated as a United States person. A "non-United States
Holder" is a beneficial owner of exchangeable shares that is not a United States
Holder. If a partnership (including for this purpose any entity treated as a
partnership for United States federal income tax purposes) is a beneficial owner
of the exchangeable shares, the partnership itself will not be subject to United
States federal income tax on a net income basis, but the United States federal
income tax treatment of a partner in the partnership will generally depend upon
the status of the partner and upon the activities of the partnership. A holder
that is a partnership and partners in such partnership are urged to consult
their tax advisers about the United States federal income tax consequences of
owning and disposing of exchangeable shares. Based on current estimates of gross
income and gross assets and the nature of the business, Nabors believes that
none of Exchangeco, Ryan or Nabors will be classified as a foreign personal
holding company or a passive foreign investment company for the current taxable
year. The status of Exchangeco, Ryan and Nabors in future years, however, will
depend on their income, assets and activities in those years. Accordingly, this
summary assumes that none of Exchangeco, Ryan or Nabors are or will be a
"foreign personal holding company" or a "passive foreign investment company" for
United States federal income tax purposes. This summary also assumes that none
of Exchangeco, Ryan or Nabors are or will be a "controlled foreign corporation"
for United States federal income tax purposes. This discussion does not address
persons subject to special provisions of United States federal income tax law,
such as tax-exempt organizations, banks, financial institutions, insurance
companies, real estate investment trusts, regulated investment companies,
dealers or traders in securities or currencies, grantor trusts, persons having a
"functional currency" other than the United States dollar, non-United States
Holders, holders who own, or are deemed to own, 10% or more, determined by
voting power or value, of exchangeable shares, holders who hold exchangeable
shares as part of a hedge, straddle, wash sale, synthetic security, conversion
transaction or other integrated investment and holders of exchangeable shares
who acquired their interests through the exercise of employee stock options or
otherwise as compensation for services. This discussion is limited to holders
who hold exchangeable shares as, and who will hold Nabors common shares as, a
capital asset as defined in the Code.

     This discussion does not address all aspects of United States federal
income taxation that may be applicable to a particular holder in light of the
holder's particular circumstances. Accordingly, all holders are urged to consult
their tax advisors with respect to the United States federal income tax
consequences to them of the ownership and disposition of exchangeable shares in
light of their particular circumstances. This discussion does not address any
aspects of United States federal income taxation that may be applicable to
holders of options or warrants. In addition, this discussion does not address
the United States state or local tax consequences or the foreign tax
consequences of the ownership and disposition of the exchangeable shares.
Holders are urged to consult their tax advisors with respect to the United
States federal, state and local tax consequences, the foreign tax consequences
and the non-tax consequences of the ownership and disposition of exchangeable
shares, Nabors common shares and ancillary rights and call rights.

UNITED STATES HOLDERS

  EXCHANGE OF EXCHANGEABLE SHARES

     There is no authority directly addressing the proper characterization of
instruments similar to the exchangeable shares together with the associated
ancillary rights and call rights or the exchange of exchangeable shares for
Nabors common shares (including an exchange upon the occurrence of an

                                        23


automatic redemption date). As a result, the consequences to a United States
Holder of such an exchange are unclear.

     A United States Holder may be justified in taking the position that the
exchangeable shares (together with the ancillary rights and call rights)
constitute stock of Nabors for United States federal income tax purposes. If the
exchangeable shares (together with the ancillary rights and call rights)
constitute stock of Nabors for United States federal income tax purposes, the
exchange of the exchangeable shares for Nabors common shares should not be a
taxable event. In such event, the aggregate tax basis of the Nabors common
shares received pursuant to the exchange would equal the United States Holder's
aggregate tax basis in the exchangeable shares and the holding period of the
Nabors common shares received by such holder would include the holding period of
the exchangeable shares surrendered in the exchange.

     Alternatively, if the exchangeable shares constitute stock of Exchangeco
for United States federal income tax purposes, a United States Holder who
exchanges its exchangeable shares for shares of Nabors common shares would
generally recognize gain or loss. Such gain or loss would be measured by the
difference, if any, between (1) the fair market value of the shares of Nabors
common shares received at the time of the exchange and (2) the United States
Holder's tax basis in the exchangeable shares surrendered, and would generally
be capital gain or loss, except with respect to any declared but unpaid
dividends on the exchangeable shares. Under this alternative characterization, a
United States Holder's tax basis in the shares of Nabors common shares received
would be equal to the fair market value of such shares at the time of the
exchange and the holding period for such shares would begin on the day after the
exchange.

     For United States federal income tax purposes, gain recognized on the
exchange of exchangeable shares for shares of Nabors common shares will
generally be treated as United States source gain. Any Canadian tax imposed on
the exchange may be available as a credit against United States federal income
taxes, subject to applicable limitations. The use of a credit may be limited or
precluded entirely if the United States Holder has no income that is treated as
non-United States source income for United States federal income tax purposes.
Alternatively, a United States Holder may be entitled to claim a deduction with
respect to any Canadian tax paid in computing United States taxable income.

  DISTRIBUTIONS ON THE EXCHANGEABLE SHARES

     Because the treatment of exchangeable shares is not clear, the treatment of
dividends with respect to such shares is also not clear. If dividends received
by a United States Holder with respect to the exchangeable shares constitute
dividends from Nabors for United States federal income tax purposes, then any
dividends paid with respect to the exchangeable shares out of Nabors' earnings
and profits generally would be treated as foreign source dividend income.

     Alternatively, if dividends received by a United States Holder with respect
to the exchangeable shares constitute dividends from Exchangeco for United
States federal income tax purposes, then any dividends paid with respect to the
exchangeable shares out of Exchangeco's earnings and profits generally would be
treated as foreign source dividend income.

     Dividends paid in Canadian dollars will be includible in the income of a
United States Holder in a United States dollar amount calculated by reference to
the exchange rate in effect on the date the dividends are deemed received.
United States Holders are urged to consult their tax advisors regarding the
treatment of any foreign currency gain or loss on any Canadian dollars received
which are not converted into United States dollars on such date.

     Under the terms of the Canada-United States Tax Convention, distributions
with respect to the exchangeable shares received by United States Holders may be
subject to Canadian withholding tax at a rate of 15% irrespective of the
treatment for United States federal income tax purposes. Subject to certain
limitations of United States federal income tax law, a United States Holder
should generally be entitled to either a credit against its United States
federal income tax liability or a deduction in computing United

                                        24


States taxable income for Canadian income taxes withheld from distributions with
respect to the exchangeable shares.

  BACKUP WITHHOLDING AND INFORMATION REPORTING

     Payments of dividends made with respect to, or the proceeds of the sale or
other disposition of, the exchangeable shares and shares of Nabors common
shares, as the case may be, may be subject to information reporting and United
States federal backup withholding tax at the then applicable rate if the
recipient of such payment fails to supply an accurate taxpayer identification
number or otherwise fails to comply with applicable United States information
reporting or certification requirements. Any amount withheld from a payment to a
United States Holder under the backup withholding rules is allowable as a credit
against the holder's United States federal income tax, provided that the
required information is furnished to the IRS.

NON-UNITED STATES HOLDERS

     A non-United States Holder should generally not be subject to United States
federal income tax as a result of the ownership and disposition of exchangeable
shares. However, as noted above, legislation has been introduced which, if
enacted in its present form, could materially change the United States federal
income tax consequences of the ownership and disposition of exchangeable shares
to non-United States Holders. It is difficult at this time to predict what, if
any, changes might occur. Non-United States Holders are urged to consult their
tax advisors regarding the possibility and effect of any such changes.

                       BERMUDA INCOME TAX CONSIDERATIONS

     Under current Bermuda law, we are not subject to tax in Bermuda on our
income or capital gains. Furthermore, we have obtained from the Minister of
Finance of Bermuda, under the Exempted Undertakings Tax Protection Act 1966, an
undertaking that, in the event that Bermuda enacts any legislation imposing tax
computed on any income or capital gains, that tax will not be applicable to us
until March 28, 2016. This undertaking does not, however, prevent the imposition
of any tax or duty on persons ordinarily resident in Bermuda or any property tax
on leasehold interests we may have in Bermuda. We will pay an annual government
fee in Bermuda based on our authorised share capital and share premium. The
maximum annual government fee applicable to us is currently $29,215, and we
expect to be subject to the maximum fee.

     Under current Bermuda law, no income, withholding or other taxes or stamp
or other duties are imposed in Bermuda upon the issue, transfer or sale of our
common shares or on any payments in respect of our common shares (except, in
certain circumstances, to persons ordinarily resident in Bermuda).

     In the opinion of Appleby, Spurling & Kempe, the exchange of exchangeable
shares for common shares of Nabors will be tax-free under Bermuda law to Nabors
and the holders of the exchangeable shares.

                                 LEGAL MATTERS

     The validity of our common shares issuable hereunder will be passed upon
for us by Appleby, Spurling & Kempe. Certain Bermuda income tax matters have
been passed on by Appleby, Spurling & Kempe, certain United States federal
income tax matters have been passed upon by Skadden, Arps, Slate, Meagher & Flom
LLP and certain Canadian federal income tax matters have been passed upon by
Stikeman Elliott.

                            INDEPENDENT ACCOUNTANTS

     The consolidated financial statements incorporated in this prospectus by
reference to Nabors' Current Report on Form 8-K filed on August 20, 2002 (File
No. 000-49887) have been so incorporated in reliance on the report of
PricewaterhouseCoopers LLP, independent accountants, given on the authority of
said firm as experts in auditing and accounting.

                                        25


     With respect to the unaudited financial information of Nabors Delaware for
the three-month periods ended March 31, 2002 and 2001 and of Nabors for the
six-month periods ended June 30, 2002 and 2001, incorporated by reference in
this prospectus, PricewaterhouseCoopers LLP reported that they have applied
limited procedures in accordance with professional standards for a review of
such information. However, their separate reports dated April 17, 2002, except
for Notes 1 and 2, as to which the date is April 29, 2002, and July 17, 2002,
except for Note 11, as to which the date is August 13, 2002, incorporated by
reference herein, state that they did not audit and they do not express an
opinion on that unaudited financial information. Accordingly, the degree of
reliance on their report on such information should be restricted in light of
the limited nature of the review procedures applied. PricewaterhouseCoopers LLP
is not subject to the liability provisions of Section 11 of the Securities Act
of 1933 for their report on the unaudited financial information because that
report is not a "report" or a "part" of the registration statement prepared or
certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11
of the Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under Bermuda law, a company is permitted to indemnify its directors and
officers subject to certain restrictions. Section One (1) and Seventy-Five (75)
of Nabors' Amended and Restated Bye-Laws, state:

          "Officer" means a Director, Secretary, or other officer of the Company
     appointed pursuant to these Bye-laws, but does not include any person
     holding the office of auditor in relation to the Company;

          "75. Exemption and Indemnification of Officers. Subject always to
     these Bye-laws, no Officer shall be liable for the acts, receipts, neglects
     or defaults of any other Officer nor shall any Officer be liable in respect
     of any negligence, default or breach of duty on his or her own part in
     relation to the Company or any Subsidiary, or for any loss, misfortune or
     damage which may happen, in or arising out of the actual or purported
     execution or discharge of his or her duties or the exercise or purported
     exercise of his or her powers or otherwise in relation to or in connection
     with his or her duties, powers or office.

          75.1. Subject always to these Bye-laws, every Officer shall be
     indemnified and held harmless out of the funds of the Company against all
     liabilities, losses, damages or expenses (including but not limited to
     liabilities under contract, tort and statute or any applicable foreign law
     or regulation and all legal and other costs and expenses properly payable)
     incurred or suffered by the Officer arising out of the actual or purported
     execution or discharge of the Officer's duties (including, without
     limitation, in respect of his or her service at the request of the Company
     as a director, officer, partner, trustee, employee, agent or similar
     functionary of another person) or the exercise or purported exercise of the
     Officer's powers or otherwise, in relation to or in connection with the
     Officer's duties, powers or office (including but not limited to
     liabilities attaching to the Officer and losses arising by virtue of any
     rule of law in respect of any negligence, default, breach of duty or breach
     of trust of which such Officer may be guilty in relation to the Company or
     any Subsidiary of the Company).

          75.2. Every Officer shall be indemnified out of the funds of the
     Company against all liabilities arising out of the actual or purported
     execution or discharge of the Officer's duties or the exercise or purported
     exercise of the Officer's powers or otherwise, in relation to or in
     connection with the Officer's duties, powers or office, incurred by such
     Officer in defending any proceedings, whether civil or criminal, in which
     judgment is given in the Officer's favour, or in which the Officer is
     acquitted, or in connection with any application under the Companies Acts
     in which relief from liability is granted to the Officer by the court.

                                       II-1


          75.3. In this Bye-law 75 (i) the term "Officer" includes, in addition
     to the persons specified in the definition of that term in Bye-law 1, the
     Resident Representative, a member of a committee constituted under these
     Bye-laws, any person acting as an Officer or committee member in the
     reasonable belief that the Officer has been so appointed or elected,
     notwithstanding any defect in such appointment or election, and any person
     who formerly was an Officer or acted in any of the other capacities
     described in this clause (i) and (ii) where the context so admits,
     references to an Officer include the estate and personal representatives of
     a deceased Officer or any such other person.

          75.4. The provisions for exemption from liability and indemnity
     contained in this Bye-law shall have effect to the fullest extent permitted
     by Applicable Law, but shall not extend to any matter which would render
     any of them void pursuant to the Companies Acts.

          75.5. To the extent that any person is entitled to claim an indemnity
     pursuant to these Bye-laws in respect of an amount paid or discharged by
     him or her, the relevant indemnity shall take effect as an obligation of
     the Company to reimburse the person making such payment (including advance
     payments of fees or other costs) or effecting such discharge.

          75.6. The rights to indemnification and reimbursement of expenses
     provided by these Bye-laws shall not be deemed to be exclusive of, and are
     in addition to, any other rights to which a person may be entitled. Any
     repeal or amendment of this Bye-law 75 shall be prospective only and shall
     not limit the rights of any Officer or the obligation of the Company with
     respect to any claim arising prior to any such repeal or amendment.

          75.7. In so far as it is permissible under Applicable Law, each
     Shareholder and the Company agree to waive any claim or right of action the
     Shareholder or it may at any time have, whether individually or by or in
     the right of the Company, against any Officer on account of any action
     taken by such Officer or the failure of such Officer to take any action in
     the performance of his duties with or for the Company, provided however,
     that such waiver shall not apply to any claims or rights of action arising
     out of the fraud or dishonesty of such Officer or to recover any gain,
     personal profit or advantage to which such Officer is not legally entitled.

          75.8. Subject to the Companies Acts, expenses incurred in defending
     any civil or criminal action or proceeding for which indemnification is
     required pursuant to this Bye-law 75 shall be paid by the Company in
     advance of the final disposition of such action or proceeding upon 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 pursuant to this Bye-law 75.

          75.9. Each Shareholder of the Company, by virtue of its acquisition
     and continued holding of a Share, shall be deemed to have acknowledged and
     agreed that the advances of funds may be made by the Company as aforesaid,
     and when made by the Company under this Bye-law 75 are made to meet
     expenditures incurred for the purpose of enabling such Officer to properly
     perform his or her duties as an Officer."

     Nabors has entered into agreements with certain of its directors and
officers indemnifying them against expenses, settlements, judgments and fines in
connection with any threatened, pending or completed action, suit, arbitration
or proceeding where the individual's involvement is by reason of the fact that
he is or was a director or officer or served at Nabors' request as a director or
officer of another organization, except where such indemnification is not
permitted under applicable law.

     The officers and directors of Nabors are covered by directors and officers
insurance aggregating $50,000,000.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Nabors pursuant
to the foregoing provisions, Nabors has been informed that, in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 17.  UNDERTAKINGS

     The undersigned registrant hereby undertakes:

          (a) (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;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this 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 this registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

             (iii) to include any material information with respect to the plan
        of distribution not previously disclosed in this registration statement
        or any material change to such information in this registration
        statement;

          provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this
     section do not apply if the information required to be included in a
     post-effective amendment by those paragraphs is contained in periodic
     reports filed with or furnished to the SEC by the registrant pursuant to
     Section 13 or Section 15(d) of the Securities Exchange Act that are
     incorporated by reference in this registration statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, 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) That, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act, and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act, that is incorporated by reference in this 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) Insofar as indemnification for liabilities arising under the Securities
Act 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 SEC such indemnification is against
public policy as expressed in the Securities Act and therefore is 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 them is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                       II-4


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing this registration statement on Form S-3 and has duly
caused this registration statement to be signed on its behalf by the
undersigned, thereunto duly authorized in Houston, Texas, on this 6th day of
September, 2002.
