Dear Sirs and Mesdames:

     Nabors Industries, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to
the several initial purchasers named in Schedule A hereto (the “Initial Purchasers”) $2,500,000,000
principal amount of its 0.94% Exchangeable Notes Due 2011 (the “Firm Notes”) to be issued pursuant
to the provisions of an Indenture to be dated as of May 23, 2006 (the “Indenture”) among the
Company, the Guarantor (as defined below) and Wells Fargo Bank, National Association as Trustee
(the “Trustee”). The Company also proposes to issue and sell to the several Initial Purchasers not
more than an additional $250,000,000 principal amount of its 0.94% Senior Exchangeable Notes Due
2011, solely to cover over-allotments (the “Additional Notes”) if and to the extent the Initial
Purchasers elect to exercise the right to purchase such Additional Notes granted to the Initial
Purchasers in Section 2 hereof. The Firm Notes and the Additional Notes, together with the
Guarantees (as defined below) are hereinafter collectively referred to as the “Notes”. The Notes
will be fully and unconditionally guaranteed (the “Guarantees”) by Nabors Industries Ltd., a
Bermuda exempted company (the “Guarantor”). The Notes will be exchangeable for shares of the
Guarantor’s Common Shares, $0.001 par value (the “Underlying Securities”). The Notes and the
Underlying Securities are hereinafter collectively referred to as the “Securities”.

     The Notes, the Guarantees and the Underlying Securities will be offered by the Initial
Purchasers without being registered under the Securities Act of 1933, as amended (the “Securities
Act”), to qualified institutional buyers in compliance with the exemption from registration
provided by Rule 144A (“Rule 144A”) .

     The Initial Purchasers and their direct and indirect transferees will be entitled to the
benefits and subject to the obligations of a Registration Rights Agreement to be dated the Closing
Date (as defined below) among the Company, the Guarantor and the Initial Purchasers (the
“Registration Rights Agreement”).

     The Company intends to use a portion of the net proceeds from the sale of the Securities to
fund the cost of exchangeable note hedge transactions that the Company expects to close
concurrently with the closing of the sale of the Securities with Bear, Stearns International
Limited and Citibank, N.A. (the “Hedge Transactions”). In addition, in connection with the sale of
the Securities and the Hedge Transactions, the Guarantor expects to sell warrants to purchase
shares of its common stock to Bear, Stearns International Limited and Citibank, N.A. (the

 

 

“Warrant Sale”). As used herein, the term “Transactions” collectively refers to the Hedge
Transactions and the Warrant Sale.

     In connection with the sale of the Securities, the Company has prepared and delivered to the
Initial Purchasers a preliminary offering memorandum, dated May 17, 2006 (together with any
exhibits thereto and the documents incorporated by reference therein, the “Offering Memorandum”)
and has prepared and delivered a pricing supplement (the “Pricing Supplement”) dated May 18, 2006,
in the form attached hereto as Schedule I, describing the terms of the Securities, the terms of the
offering and a description of the Company and the Guarantor, each for use by the Initial Purchasers
in connection with their solicitation of offers to purchase the Securities. As used herein,
“Disclosure Package” shall mean the Offering Memorandum, as supplemented by the Pricing Supplement
and any written communications (as defined in Rule 405 under the Securities Act) authorized for use
under Section 6(e), each in the most recent form that has been prepared and delivered by the
Company to the Initial Purchasers in connection with their solicitation of offers to purchase the
Securities as of the Applicable Time. “Applicable Time” means 9:00 A.M. (EST) on May 18, 2006.
Promptly after the Applicable Time and in any event no later than the Closing Date (as defined in
Section 4), the Company will prepare and deliver to the Initial Purchasers a final offering
memorandum (the “Final Memorandum”), which will consist of the Offering Memorandum with only such
changes therein as are required to reflect the information contained in the Pricing Supplement.
The Offering Memorandum and the Final Memorandum are each sometimes referred to herein as a
“Memorandum.” As used herein (including the schedule and annexes hereto), the term “Memorandum”
shall include in each case the documents incorporated by reference therein. The terms
“supplement”, “amendment” and “amend” as used herein with respect to the Memorandum shall include
all documents deemed to be incorporated by reference in the Memorandum that are filed subsequent to
the date of the Memorandum with the Securities and Exchange Commission (the “Commission”) pursuant
to the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

1. Representations

of the Applicable Time the Disclosure Package did not or will not contain, and on and as of
the Closing Date, the Disclosure Package and the Final Memorandum will not contain, any
untrue statement of a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not
misleading, except that the representations and warranties set forth in this paragraph do
not apply to statements or omissions in the Disclosure Package or the Final Memorandum based

     2. Agreements to Sell and Purchase.
The Company hereby agrees to sell to the Initial Purchasers,
and the Initial Purchasers, upon the basis of the representations and warranties herein contained,
but subject to the conditions hereinafter stated, agree, severally and not jointly, to purchase
from the Company the principal amount at maturity of Firm Notes set forth opposite

Purchaser’s name on Schedule A hereto at a purchase price of 99.00% of the principal amount thereof
(the “Purchase Price”).

     On the basis of the representations and warranties contained in this Agreement, and subject to
its terms and conditions, the Company agrees to sell to the Initial Purchasers the Additional
Notes, and the Initial Purchasers shall have the right to purchase, solely to cover
over-allotments, severally and not jointly, up to $250,000,000 principal amount of Additional Notes
at the Purchase Price, plus accrued interest, if any, from the Closing Date to the Option Closing
Date. Such right may be exercised by the Initial Purchasers on one or more occasions, but the
total principal amount that may be acquired pursuant to such exercises shall be limited to
$250,000,000. Each time the Initial Purchasers elect to exercise such right, the Initial
Purchasers shall so notify the Company in writing not later than 13 days after the Closing Date,
which notice shall specify the principal amount of Additional Notes to be purchased by the Initial
Purchasers and the date on which such Additional Notes are to be purchased. Such date may be the
same as the Closing Date but not earlier than the Closing Date nor later than three business days
after the date of such notice. Additional Notes may be purchased as provided in Section 4. The
principal amount of Additional Notes to be sold to each Initial Purchaser shall be the principal

Purchaser on Schedule A hereto bears to the aggregate principal amount of Firm Notes, as adjusted
pursuant to Section 10.

     Each of the Company and the Guarantor hereby agrees that, without the prior written consent of
the Initial Purchasers, which consent will not be unreasonably withheld, it will not, during the
period ending 90 days after the date of the Final Memorandum, (i) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or
indirectly, any common shares or any securities convertible into or exercisable or exchangeable for
common shares of the Guarantor or (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of the common shares of
the Guarantor, whether any such transaction described in clause (i) or (ii) above is to be settled
by delivery of common shares of the Guarantor or such other securities, in cash or otherwise. The
foregoing sentence shall not apply to (A) the sale of the Securities under this Agreement, (B) the
issuance by the Guarantor of any common shares upon the exercise of an option or warrant or the
conversion of a security outstanding on the date hereof, (C) issuances and purchases pursuant to
the Transactions, (D) the issuance by the Guarantor of common shares as consideration in an
acquisition of the stock or assets of another entity or any contract or offer to enter into a
contract therefor or (E) the grant or issuance of any securities of the type described in the
immediately preceding sentence pursuant to employee benefit or compensation plans or agreements.

     The Company hereby agrees that, without the prior written consent of the Initial Purchasers,
it will not, during the period beginning on the date hereof and continuing to and including the
Closing Date, offer, sell, contract to sell or otherwise dispose of any debt of the Company or
warrants to purchase debt of the Company in each case of a type substantially similar to the Notes
(other than the sale of the Notes under this Agreement).

-6-

 

     3. Terms of Offering.
You have advised the Company and the Guarantor that the Initial Purchasers
will make an offering of the Securities to be purchased by the Initial Purchasers hereunder on the
terms set forth in this Agreement and the Offering Memorandum.

     4. Payment and Delivery.
Payment of the Purchase Price for the Firm Notes and the related
Guarantees shall be made to the Company in Federal or other funds immediately available in New York
City against delivery of such Firm Notes for the account of the Initial Purchasers at 10:00 a.m.,
New York City time, on May 23, 2006, or at such other time on the same or such other date, as shall
hereafter be agreed upon by the Company and the Initial Purchasers. The time and date of such
payment are hereinafter referred to as the “Closing Date.”

     Payment for any Additional Notes and related Guarantees shall be made to the Company in
Federal or other funds immediately available in New York City against delivery of such Additional
Notes for the account of the Initial Purchasers at 10:00 a.m., New York City time, on the date
specified in the notice described in Section 2 or at such other time on the same or on such other
date, in any event not later than June 8, 2006, as shall be designated in writing by the Initial
Purchasers. The time and date of each such payment are hereinafter referred to as an “Option
Closing Date”.

     Delivery of the Firm Notes and the Additional Notes, as the case may be, shall be made through
the facilities of The Depository Trust Company (“DTC”) pursuant to its Full-Fast Delivery Program
unless the Initial Purchasers shall otherwise instruct, and Securities sold by the Initial
Purchasers in reliance on Rule 144A (the “144A Securities”) shall be represented by one or more
global certificates.

     5. Conditions to the Initial Purchasers’ Obligations.
The obligations of the several Initial
Purchasers to purchase and pay for the Firm Notes and related Guarantees on the Closing Date are
subject to the following conditions:

     (a) Subsequent to the execution and delivery of this Agreement and prior to the Closing
Date there shall not have occurred any change, or any development involving a prospective
change, in the financial position, or in the earnings, business or operations of the
Guarantor and its subsidiaries, taken as a whole, from that set forth in the Offering
Memorandum (exclusive of any amendments or supplements thereto subsequent to the date of
this Agreement) that, in your judgment, is material and adverse and that makes it, in your
judgment, impracticable to market the Securities on the terms and in the manner contemplated
in the Offering Memorandum.

     (b) The Initial Purchasers shall have received on the Closing Date a certificate, dated
the Closing Date and signed by an executive officer of each of the Company, with respect to
the Company, and the Guarantor, with respect to the Guarantor, to the effect set forth in
Section 5(a)(i) and (ii) and to the effect that the representations and warranties of the
Company and the Guarantor contained in this Agreement are true and correct as of the Closing
Date and that each of the Company and the Guarantor has complied with all of the agreements
and satisfied all of the conditions on its part to be performed or satisfied hereunder on or
before the Closing Date.

-7-

 

     The officer signing and delivering such certificate may rely upon the best of his or her
knowledge as to proceedings threatened.

     (c) The Company and the Guarantor shall have furnished to the Initial Purchasers the
opinion of Bruce M. Taten, Vice President and General Counsel of Nabors Corporate Services,
Inc., dated the Closing Date, substantially to the effect set forth on Annex 5(c) hereto.
In giving such opinion, such counsel may rely as to matters of fact, to the extent such
counsel deems proper, on certificates of responsible officers of the Company or the
Guarantor and the Significant Subsidiaries and of public officials. Such opinion may be
relied upon only by the Initial Purchasers in connection with the transactions contemplated
by this Agreement, and may not be used or relied upon by the Initial Purchasers for any
other purpose, or by any other person, firm, corporation or entity for any purpose
whatsoever, without the prior written consent of such counsel. Such opinion may be limited
to the laws of the State of Texas and the General Corporation Law of the State of Delaware.
As to Significant Subsidiaries that are not Selected Subsidiaries (as defined in Annex
5(c)), the Company will deliver opinions from counsel in the jurisdiction of formation,
substantially to the effect set forth in Section (i) of Annex 5(c).

     (d) The Company and the Guarantor shall have furnished to the Initial Purchasers the
opinion of Milbank, Tweed, Hadley & McCloy LLP, special United States counsel for the
Company and the Guarantor, dated the Closing Date, substantially to the effect set forth on
Annex 5(d) hereto. In rendering their opinions pursuant to this Section 5(d), such counsel
may rely, to the extent deemed advisable by such counsel, (i) as to factual matters on
certificates of officers of the Company or the Guarantor and (ii) upon certificates of
public officials. Such counsel shall also state that such counsel has participated in
conferences with officers, employees and representatives of the Company and the Guarantor,
the independent public accountants of the Company and the Guarantor and the Initial
Purchasers and their counsel, at which conferences such counsel made inquiries of such
officers, Initial Purchasers and accountants, discussed in detail the contents of the
Disclosure Package and the Final Memorandum and (without taking any further action to verify
independently the statements made in the Disclosure Package and the Final Memorandum and,
except as stated in Sections (ii) and (viii) of Annex 5(d), without assuming any
responsibility for the accuracy, completeness or fairness of such statements) that nothing
has come to such counsel’s attention that would lead such counsel to believe that the
Disclosure Package, as of the Applicable Time and at the Closing Date, or the Final
Memorandum as of its date and at the Closing Date, contained or contains an untrue statement
of a material fact or omitted or omits to state a material
fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading (it being understood
that such counsel need express no opinion or comment with respect to the financial
statements and other financial and statistical information contained or incorporated by
reference therein).

     Such opinion shall be limited to the laws of the State of New York, the Federal laws of
the United States and the General Corporation Law of the State of Delaware. Such opinion
shall be rendered as of the Closing Date only in connection with this

-8-

 

Agreement and will be
solely for the benefit of the Initial Purchasers, and may not be relied upon, nor shown to
or quoted from, for any other purpose, or to any other person, firm or corporation.

     (e) The Company and the Guarantor shall have furnished to the Initial Purchasers the
opinion of Appleby Spurling Hunter, special counsel for the Guarantor, dated the Closing
Date, substantially to the effect set forth on Annex 5(e) hereto. Such opinion shall be
limited to the laws of Bermuda. Such opinion shall be rendered as of the Closing Date only
in connection with the Agreement and will be solely for the benefit of the Initial
Purchasers, and may not be relied upon, nor shown to or quoted from, for any other purpose,
or to any other person, firm or corporation.

     (f) The Initial Purchasers shall have received from Vinson & Elkins L.L.P., counsel for
the Initial Purchasers, such opinion or opinions, dated the Closing Date, with respect to
the issuance and sale of the Securities, the Disclosure Package, the Final Memorandum and
other related matters as the Initial Purchasers may reasonably require, and the Company and
the Guarantor shall have furnished to such counsel such documents as such counsel reasonably
requests for the purpose of enabling such counsel to pass upon such matters.

     (g) The Initial Purchasers shall have received on the Closing Date letters, dated the
date of the Applicable Time and Closing Date, in form and substance satisfactory to the
Initial Purchaser, from PricewaterhouseCoopers LLP, independent public accountants,
containing statements and information of the type ordinarily included in accountants’
“comfort letters” to underwriters with respect to the financial statements and certain
financial information contained in or incorporated by reference into each Memorandum;
provided that the letter delivered on the Closing Date shall use a “cut-off date” not
earlier than the date hereof.

     The obligations of the several Initial Purchasers to purchase Additional Notes hereunder are
subject to the same conditions and the delivery to you on each Option Closing Date of each of the
same documents as set forth in Section 5(a) through (g) above (or, with regard to documents and
opinions, “bring down letters” reaffirming as of the Option Closing Date the facts or other
opinions or statements contained in such documents and opinions) and such other matters as you may
reasonably request related to the execution, authentication and issuance of the Additional Notes.

     6. Covenants of the Company and the Guarantor
In further consideration of the agreements of the Initial Purchasers contained in this
Agreement, the Company and the Guarantor, jointly and severally, covenant with the Initial
Purchasers as follows:

     (a) To furnish to the Initial Purchasers in New York City, without charge, prior to
10:00 a.m. New York City time on May 23, 2006 and during the period mentioned in Section
6(c), as many copies of the Disclosure Package, the Memorandum, any documents incorporated
by reference therein and any supplements and amendments thereto as the Initial Purchasers
may reasonably request.

-9-

 

     (b) Before amending or supplementing the Disclosure Package or the Memorandum, to
furnish to the Initial Purchasers a copy of each such proposed amendment or supplement and
not to use any such proposed amendment or supplement to which the Initial Purchasers
reasonably object.

     (c) If, during such period after the date hereof and prior to the date on which all of
the Securities shall have been sold by the Initial Purchasers, any event shall occur or
condition exist as a result of which it is necessary to amend or supplement the Disclosure
Package or the Memorandum in order to make the statements therein, in the light of the
circumstances when the Disclosure Package or the Memorandum is delivered to a purchaser, not
misleading, or if, in the opinion of counsel for the Initial Purchasers, it is necessary to
amend or supplement the Disclosure Package or the Memorandum to comply with applicable law,
forthwith to prepare and furnish, at its own expense, to the Initial Purchasers, either
amendments or supplements to the Disclosure Package or the Memorandum so that the statements
in the Disclosure Package or the Memorandum as so amended or supplemented will not, in the
light of the circumstances when the Disclosure Package or the Memorandum is delivered to a
purchaser, be misleading or so that the Disclosure Package or the Memorandum, as amended or
supplemented, will comply with applicable law.

     (d) To endeavor to qualify the Securities for offer and sale under the securities or
Blue Sky laws of such jurisdictions as the Initial Purchasers shall reasonably request;
provided, however that neither the Company nor the Guarantor shall be obligated to file any
general consent to service of process or to qualify as a foreign corporation or as a dealer
in securities in any jurisdiction in which it is not so qualified or to subject itself to
taxation in respect of doing business in any jurisdiction in which it is not otherwise so
subject.

     (e) Whether or not the transactions contemplated in this Agreement are consummated or
this Agreement is terminated, to pay or cause to be paid all expenses incident to the
performance of their respective obligations under this Agreement, including: (i) the fees,
disbursements and expenses of the Company’s and the Guarantor’s counsel and the Company’s
and the Guarantor’s accountants in connection with the issuance and sale of the Securities
and all other fees or expenses of the Company and the Guarantor in connection with the
preparation of the Disclosure Package and the Memorandum and all amendments and supplements
thereto, including all printing costs associated therewith, and the delivery of copies
thereof to the Initial Purchasers, in the
quantities herein above specified, (ii) all costs and expenses related to the issuance,
transfer and delivery of the Securities to the Initial Purchasers, including any transfer or
other taxes payable thereon, (iii) the cost of printing or producing any blue sky or legal
investment memorandum in connection with the offer and sale of the Securities under state
securities laws and all expenses in connection with the qualification of the Securities for
offer and sale under state securities laws as provided in Section 6(d) hereof, including
filing fees and the reasonable fees and disbursements of counsel for the Initial Purchasers
in connection with such qualification and in connection with the Blue Sky or legal
investment memorandum, (iv) any fees charged by rating agencies for the rating of the
Securities, (i) the fees and expenses, if any, incurred in connection with the admission of

-10-

 

the Securities for trading in PORTAL or any appropriate market system, (vi) the costs and
charges of the Trustee and any transfer agent, registrar or depositary, and (vii) all other
costs and expenses incident to the performance of the obligations of the Company and the
Guarantor hereunder for which provision is not otherwise made in this Section. It is
understood, however, that except as provided elsewhere in this Agreement, the Initial
Purchasers will pay all of their costs and expenses, including fees and disbursements of
their counsel, transfer taxes payable upon resale of any of the Securities by them and any
advertising expenses connected with any offers they may make.

     (f) Neither the Guarantor nor any Affiliate will sell, offer for sale or solicit offers
to buy or otherwise negotiate in respect of any security (as defined in the Securities Act)
which could be integrated with the sale of the Securities in a manner that would require the
registration under the Securities Act of the Securities.

     (g) Not to solicit any offer to buy or offer or sell the Securities by means of any
form of general solicitation or general advertising (as those terms are used in Regulation D
under the Securities Act) or in any manner involving a public offering within the meaning of
Section 4(2) of the Securities Act.

     (h) While any of the Securities remain “restricted securities” within the meaning of
the Securities Act, to make available, upon request, to any seller of such Securities the
information specified in Rule 144A(d)(4) under the Securities Act, unless the Guarantor is
then subject to Section 13 or 15(d) of the Exchange Act.

     (i) Until the effectiveness of the shelf registration statement contemplated by the
Registration Rights Agreement, the Guarantor will not, and will not permit any of its
affiliates (as defined in Rule 144 under the Securities Act) to resell any of the Notes
which constitute “restricted securities” under Rule 144 that have been reacquired by any of
them.

     (j) The Guarantor shall use its reasonable best efforts to have the Underlying
Securities authorized (subject to official notice of issuance) for listing on The New York
Stock Exchange as promptly as practicable following the execution hereof.

     (k) Before using, authorizing, approving or referring to any written communication that
constitutes an offer to sell or a solicitation to buy the Notes or the Guarantees (other
than the Disclosure Package and the Final Memorandum), the
Company will furnish to the Initial Purchasers a copy of such written communication for
review and will not use, authorize, approve or refer to any such written communication to
which the Initial Purchasers reasonably object.

     7. Offering of Securities; Restrictions on Transfer.
(a) Each Initial Purchaser, severally and
not jointly, represents, warrants and agrees that (i) it is a qualified institutional buyer as
defined in Rule 144A under the Securities Act (a “QIB”), and an “accredited investor” within the
meaning of Rule 501 under the Securities Act, (ii) it has not solicited offers for, or offered or
sold, and will not solicit offers for, or offer or sell, such Securities by any form of general
solicitation or general advertising (as those terms are used in Regulation D under the Securities

-11-

 

Act) or in any manner involving a public offering within the meaning of Section 4(2) of the
Securities Act and (iii) it will solicit offers for such Securities only from, and will offer such
Securities only to persons that it reasonably believes to be QIBs in transactions pursuant to Rule
144A and in connection with each such sale, it has taken or will take reasonable steps to ensure
that such sale is being made in reliance on Rule 144A. Each Initial Purchaser will comply with all
applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or
delivers Securities or has in its possession or distributes the Disclosure Package or the
Memorandum or any such other material, in all cases at its own expense, except as provided in
Section 6(e).

     (b) Each Initial Purchaser acknowledges and agrees that the Company and, for the purposes of
the opinions to be delivered to the Initial Purchaser pursuant to Sections 5(c), 5(d), 5(e) and
5(f) by counsel for the Company, counsel for the Guarantor and counsel for the Initial Purchasers,
respectively, may rely upon the accuracy of the representations and warranties of such Initial
Purchaser, and compliance of such Initial Purchaser with its agreements, contained in paragraph
7(a) above, and such Initial Purchaser hereby consents to such reliance.

     8. Indemnity and Contribution.
(a) The Company and the Guarantor, jointly and severally, agree to
indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any
Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act from and against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Offering Memorandum, the Disclosure Package or the Final
Memorandum, or in any amendment or supplement, or caused by any omission or alleged omission to
state therein a material fact necessary to make the statements therein in the light of the
circumstances under which they were made not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or alleged untrue
statement or omission based upon information furnished to the Company in writing by the Initial
Purchasers expressly for use therein, it being understood and agreed that the only information
furnished by any such Initial Purchaser consists of the information described in Section 8(b);

     (b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold
harmless the Company, its directors, its officers, the Guarantor, its directors, its
officers and each other person, if any, who controls the Company or the Guarantor
within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same extent as the foregoing indemnity from the Company and the Guarantor to the
Initial Purchasers, but only with reference to information relating to the Initial
Purchasers furnished in writing by the Initial Purchasers to the Company expressly for use
in the Offering Memorandum, the Disclosure Package or the Final Memorandum or any amendments
or supplements thereto, it being understood and agreed that the only information furnished
by any such Initial Purchaser consists of the following information in the Offering
Memorandum: the third (first sentence only), seventh (fifth, sixth and seventh sentences
only) and eighth paragraphs under the caption “Plan of Distribution.

-12-

 

     (c) In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought pursuant to
Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person
against whom such indemnity may be sought (the “indemnifying party”) in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and disbursements
of such counsel related to such proceeding. In any such proceeding, any indemnified party
shall have the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests between them.
It is understood that the indemnifying party shall not, in respect of the legal expenses of
any indemnified party in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm (in
addition to any local counsel) for all such indemnified parties and that all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing
by the Initial Purchasers, in the case of parties indemnified pursuant to Section 8(a), and
by the Guarantor, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an indemnifying
party to reimburse the indemnified party for fees and expenses of counsel as contemplated by
the second and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its written consent if
(i) such settlement is entered into more than 30 days after receipt by such indemnifying
party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed
the indemnified party in accordance with such request prior to the date of such settlement.
No indemnifying party shall, without the prior written consent of the indemnified party,
effect any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been sought
hereunder by such indemnified party, unless such settlement includes an unconditional
release of such indemnified party from all liability on claims that are the subject matter
of such proceeding.

     (d) To the extent the indemnification provided for in Section 8(a) or 8(b) is
unavailable to an indemnified party or insufficient in respect of any losses, claims,
damages or liabilities referred to therein, then each indemnifying party under such
paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to
the amount paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company or the Guarantor on the one hand and the Initial

-13-

 

Purchasers
on the other hand from the offering of the Securities or (ii) if the allocation provided by
clause 8(d)(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above
but also the relative fault of the Company or the Guarantor on the one hand and of the
Initial Purchasers on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative benefits received by the Company or the Guarantor on
the one hand and the Initial Purchasers on the other hand in connection with the offering of
the Securities shall be deemed to be in the same respective proportions as the net proceeds
from the offering of the Notes (before deducting expenses) received by the Company and the
total discounts and commissions received by the Initial Purchasers, in each case as set
forth in the Offering Memorandum or herein, bear to the aggregate offering price of the
Notes. The relative fault of the Company or the Guarantor on the one hand and of the
Initial Purchasers on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the Company or
by the Initial Purchasers and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     (e) The Company, the Guarantor and the Initial Purchasers agree that it would not be
just or equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation or by any other method of allocation that does not take account of the equitable
considerations referred to in Section 8(d). The amount paid or payable by an indemnified
party as a result of the losses, claims, damages and liabilities referred to in Section 8(d)
shall be deemed to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this Section 8, no
Initial Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Notes resold by it in the initial placement of such Notes
were offered to investors exceeds the amount of any damages that such Initial Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The remedies provided for in
this Section 8 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified
party at law or in equity. The Initial Purchasers’ obligations to contribute pursuant
to this Section 8 are several in proportion to the respective principal amount of Notes they
have agreed to purchase hereunder and not joint.

     (f) The indemnity and contribution provisions contained in this Section 8 and the
representations, warranties and other statements of the Company or the Guarantor contained
in this Agreement shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of any Initial
Purchaser or any person controlling any Initial Purchaser or by or on behalf of the Company,
its officers or directors, the Guarantor, its officers or directors or any other

-14-

 

person
controlling the Company or the Guarantor and (iii) acceptance of and payment for any of the
Notes.

     9. Termination.
This Agreement shall be subject to termination by notice given by the Initial
Purchasers to the Company and the Guarantor, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been suspended or
materially limited on or by, as the case may be, any of the New York Stock Exchange, the American
Stock Exchange, the NASDAQ National Market, or settlement of trading shall have been materially
disrupted, (ii) trading of any securities of the Guarantor shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York State authorities or
(iv) there shall have occurred any outbreak or escalation of hostilities (including without
limitation an act of terrorism) or any change in financial markets or any calamity or crisis that,
in your judgment, is material and adverse to the financial markets generally and (b) in the case of
any of the events specified in clauses 9(a)(i) through 9(a)(iv), such event, singly or together
with any other such event, makes it, in your judgment, impracticable to market the Securities on
the terms and in the manner contemplated by this Agreement and the Offering Memorandum.

     10. Default by an Initial Purchaser.
If any one or more Initial Purchasers shall fail to purchase
and pay for any of the Notes agreed to be purchased by such Initial Purchaser hereunder and such
failure to purchase shall constitute a default in the performance of its or their obligations under
this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay
for (in the respective proportions that the principal amount of Notes set forth opposite their
names in Schedule A hereto bears to the aggregate principal amount of Notes set forth opposite the
names of all the remaining Initial Purchasers) the Notes that the defaulting Initial Purchaser or
Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the
aggregate principal amount of Notes that the defaulting Initial Purchaser or Initial Purchasers
agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Notes set forth
in Schedule A hereto, the remaining Initial Purchasers shall have the right to purchase all, but
shall not be under any obligation to purchase any, of the Notes, and if such nondefaulting Initial
Purchasers do not purchase all the Notes, this Agreement will terminate without liability to any
nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser
as set forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding
five Business
Days, as the Initial Purchasers shall determine in order that the required changes in the Final
Memorandum or in any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company
or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

     11. Effectiveness; Expense Reimbursement.
This Agreement shall become effective upon the execution
and delivery hereof by the parties hereto.

     If this Agreement shall be terminated by the Initial Purchasers because of any failure or
refusal on the part of the Company or the Guarantor to comply with the terms or to fulfill any of
the conditions of this Agreement, or if for any reason the Company or the Guarantor shall be unable
to perform its obligations under this Agreement, the Company will reimburse the Initial

-15-

 

Purchasers
for all out-of-pocket expenses (including the fees and disbursements of their counsel up to a
maximum of $100,000), reasonably incurred by the Initial Purchasers in connection with this
Agreement or the offering contemplated hereunder.

     12. Notices.
Notices given pursuant to this Agreement shall be in writing and shall be delivered
(a) if to the Company, at 515 W. Greens Road, Suite 1200, Houston, Texas 77067, Attention: Chief
Financial Officer, or (b) if to the Guarantor, Mintflower Place, 8 Par-La-Ville Road, Hamilton,
HM08, Bermuda, or (c) if to the Initial Purchasers, Citigroup Global Markets Inc., at the offices
of 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, and at the offices
of Lehman Brothers Inc., Syndicate Registration, 745 Seventh Avenue, New York, N.Y. 10019, or in
any case to such other address as the person to be notified may have requested in writing.

     13. Successors.
This Agreement is made solely for the benefit of the Initial Purchasers, the
Company, the Guarantor, their respective directors and officers and other controlling persons
referred to in Section 8 hereof, and their respective successors and assigns, and no other person
shall acquire or have any right under or by virtue of this Agreement. The term “successors and
assigns” as used in this Agreement shall not include a purchaser from the Initial Purchasers of any
of the Securities in its status as such purchaser.

     14. Partial Unenforceability.
If any section, paragraph or provision of this Agreement is for any
reason determined to be invalid or unenforceable, such determination shall not affect the validity
or enforceability of any other section, paragraph or provision hereof.

     15. Waiver of Tax Confidentiality
Notwithstanding anything herein to the contrary, purchasers of the Securities and the parties to
this Agreement and each employee, representative or other agent of the Company and the Guarantor
may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and
U.S. tax structure of any transaction contemplated herein and all materials of any kind (including
opinions or other tax analyses) that are, have been or will be provided relating to such U.S. tax
treatment and U.S tax structure, other than any information for which nondisclosure is reasonably
necessary in order to comply with applicable federal or state securities laws.

     16. Counterparts.
This Agreement may be signed (including by facsimile) in any number of
counterparts, each of which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument.

     17. Applicable Law.
This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York.

     18. No Fiduciary Duty.
The Company and Guarantor hereby acknowledge that (a) the purchase and sale
of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the
Company and the Guarantor, on the one hand, and the Initial Purchasers and any affiliate through
which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as
an agent or fiduciary of the Company or the Guarantor and (c) the Company’s engagement of the
Initial Purchasers in connection with the offering and the process leading up to the offering is as
independent contractors and not in any other capacity.

-16-

 

Furthermore, the Company and the Guarantor
agree that they are solely responsible for making their own judgments in connection with the
offering (irrespective of whether any of the Initial Purchasers has advised or is currently
advising the Company or the Guarantor on related or other matters). The Company and the Guarantor
agree that they will not claim that the Initial Purchasers have rendered advisory services of any
nature or respect, or owe an agency, fiduciary or similar duty to the Company or the Guarantor, in
connection with such transaction or the process leading thereto.

     19. Headings.
The headings of the sections of this Agreement have been inserted for convenience of
reference only and shall not be deemed a part of this Agreement.

ANNEX 5(C )

OPINION OF BRUCE M. TATEN

               (i) each of the Company, Nabors Drilling USA, LP, Nabors Holding Company, Nabors
Industries Inc., Nabors International Finance Inc., Ryan Energy Technologies Inc., Oak Leaf
Investments Inc., Nabors Diamond Holdings, Inc., Nabors Well Services Co. (collectively, the
“Selected Subsidiaries”), has been duly organized and is validly existing as a corporation
or limited partnership in good standing under the laws of the jurisdiction in which it is
chartered or organized, with full corporate or partnership power and authority to own its
properties and conduct its business as described in the Offering Memorandum, and is duly
qualified to do business as a foreign corporation or limited partnership and is in good
standing under the laws of each jurisdiction which requires such qualification wherein it
owns or leases properties or conducts business, except to the extent that the failure to be
so qualified or be in good standing would not have a material adverse effect on the
Guarantor and its subsidiaries, taken as a whole;

               (ii) all outstanding shares of capital stock (or limited partnership interests) of each
of the Company and the other Significant Subsidiaries are owned by the Guarantor either
directly or through wholly owned subsidiaries free and clear of any perfected security
interest, other than any perfected security interest in favor of the Guarantor or another
Significant Subsidiary and, to the knowledge of such counsel, any other security interests,
claims, liens or encumbrances other than any liens, encumbrances, equities or claims in
favor of the Guarantor or another Significant Subsidiary;

               (iii) to the knowledge of such counsel, there is no pending or threatened material
action, suit or proceeding before any court or governmental agency, authority or body or any
arbitrator involving the Guarantor or any of its subsidiaries of a character required to be
disclosed in the Offering Memorandum which is not disclosed in the Offering Memorandum;

               (iv) such counsel has no reason to believe that the Offering Memorandum, as of the
Applicable Time and at the Closing Date, or the Final Memorandum, as of its date and at the
Closing Date, included or includes any untrue statement of a material fact or omitted or
omits to state a material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading (it being understood that such
counsel need express no opinion or comment with respect to the financial statements and the
other financial and statistical information contained or incorporated by reference therein);

               (v) neither the issue and sale of the Securities, the consummation of the Transactions,
nor the consummation of any other of the transactions herein contemplated nor the
fulfillment of the terms hereof will conflict with, result in a breach or violation of, or
constitute a default under the terms of (A) any indenture or other agreement or instrument
known to such counsel and to which the Company, the

-22-

 

Guarantor or any of the Significant Subsidiaries is a party or bound, or any judgment,
order or decree known to such counsel to be applicable to the Company, the Guarantor or any
of the Significant Subsidiaries of any court, regulatory body, administrative agency,
governmental body or arbitrator having jurisdiction over the Company, the Guarantor or any
of the Significant Subsidiaries, except such as would not, either singly or in the
aggregate, have a material adverse effect upon the Guarantor and its subsidiaries, taken as
a whole, or prevent the Company or the Guarantor from performing its obligations under this
Agreement, the Registration Rights Agreement or the Indenture or (B) the respective charters
or bylaws of the Significant Subsidiaries (assuming that the relevant laws of the state of
incorporation of any Significant Subsidiary not incorporated in Texas or Delaware are the
same as those of Texas).

ANNEX 5(D)(I)

OPINION OF MILBANK, TWEED, HADLEY & McCLOY LLP

               (i) the Company has been duly incorporated and is validly existing as a corporation in
good standing under the laws of the State of Delaware;

               (ii) the statements in the Offering Memorandum under “Description of Notes,” and
“Transfer Restrictions” insofar as such statements constitute a summary of the documents or
legal matters referred to therein, fairly present in all material respects the information
called for with respect to such documents or legal matters;

               (iii) based upon the representations, warranties and agreements of the Company and the
Guarantor in Sections 1(l), 1(n), 6(f) and 6(g) of this Agreement and of the Initial
Purchaser in Section 7 of this Agreement, it is not necessary in connection with the offer,
sale and delivery of the Securities to the Initial Purchaser under this Agreement or in
connection with the initial resale of such Securities by the Initial Purchaser in accordance
with Section 7 of this Agreement to register the Securities under the Securities Act of 1933
or to qualify the Indenture under the Trust Indenture Act of 1939;

               (iv) each of the Indenture and the Registration Rights Agreement has been duly
authorized, executed and delivered by the Company, and, assuming each has been duly
authorized, executed and delivered by the Guarantor and the Indenture has been duly
authorized, executed and delivered by the Trustee, it constitutes a legal, valid and binding
agreement enforceable against the Company and the Guarantor in accordance with its terms
(subject to the qualification that enforceability of the obligations of the Company and the
Guarantor thereunder may be limited by (i) bankruptcy, fraudulent conveyance or transfer,
insolvency, reorganization, moratorium and other similar laws relating to or affecting
creditors’ rights generally, and (ii) the application of general principles of equity
(regardless of whether considered in a proceeding at law or in equity) including, without
limitation, (a) the possible unavailability of specific performance, injunctive relief or
any other equitable remedy and (b) concepts of good faith, reasonableness, fair dealing and
materiality, and except as rights to indemnification and contribution under the Registration
Rights Agreement may be limited by public policy or law); and the Notes have been duly
authorized by the Company and, when executed and authenticated in accordance with the
provisions of the Indenture and delivered to and paid for by the Initial Purchaser pursuant
to this Agreement, will constitute legal, valid and binding obligations of the Company
entitled to the benefits of the Indenture (subject to the qualification that enforceability
of the obligations of the Company thereunder may be limited by (i) bankruptcy, fraudulent
conveyance or transfer, insolvency, reorganization, moratorium and other similar laws
relating to or affecting creditors’ rights generally, and (ii) the application of general
principles of equity (regardless of whether considered in a proceeding at law or in equity)
including, without limitation, (a) the possible unavailability of specific performance,

-24-

 

injunctive relief or any other equitable remedy and (b) concepts of good faith,
reasonableness, fair dealing and materiality);

               (v) this Agreement has been duly authorized, executed and delivered by the Company;

               (vi) no consent, approval, authorization or order of any court or governmental agency
or body is required of the consummation of the transactions contemplated herein, except such
as may be required under the blue sky laws of any jurisdiction in connection with the
purchase and distribution of the Securities by the Initial Purchaser (as to which such
counsel need express no opinion) and by Federal and state securities laws with respect to
the Company’s and the Guarantors’ obligations under the Registration Rights Agreement;

               (vii) neither the issue and sale of the Securities, nor the consummation of any other
of the transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation of, or constitute a default under any
provision of (A) applicable law, except such as would not, either singly or in the
aggregate, have a material adverse effect upon the Guarantor and its subsidiaries, taken as
a whole, or prevent the Company or the Guarantor from performing its obligations under this
Agreement, the Registration Rights Agreement or the Indenture, or (B) the Restated
Certificate of Incorporation or By-Laws of the Company; and

               (vii) although the statements in the Offering Memorandum under the caption “Certain
Material United States Federal Income Tax Considerations” (the “Discussion”) do not purport
to discuss all possible United States federal income tax consequences of the acquisition,
ownership, and disposition of Notes, we are of the opinion that, subject to the limitations,
qualifications, exceptions, and assumptions set forth therein, the Discussion constitutes a
fair and accurate summary under current law of the anticipated material United States
federal income tax consequences of the acquisition, ownership, and disposition of Notes and
of any of the Guarantor’s Common Shares received pursuant to an exchange of the Notes.
