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 Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 750,000 Additional Shares at the Purchase Price, solely to cover over-allotments. The Representative of the Underwriters may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of the Prospectus.

On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth on Schedule A hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

3. Terms of Offering. You have advised the Company that the Underwriters will make an offering of the Shares to be purchased by the Underwriters hereunder on the terms set forth in this Agreement and the Disclosure Package.

4. Payment and Delivery.

The time and date of such payment are hereinafter referred to as the “Closing Date.”

Payment for any Additional Shares shall be made to the Company in Federal or other funds immediately available in New York City on the date specified in the corresponding notice described in Section 2 or at such other time on the same or on such other date, in any event not later than the tenth business day thereafter, as may be designated in writing by the Representative.

The Firm Shares and the Additional Shares shall be registered in such names and in such denominations as you shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor.

(e) If the Disclosure Package is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Disclosure Package conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Disclosure Package to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own

expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Disclosure Package so that the statements in the Disclosure Package as so amended or supplemented will not, in the light of the circumstances when the Disclosure Package is delivered to a prospective purchaser, be misleading or so that the Disclosure Package, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Disclosure Package, as amended or supplemented, will comply with applicable law.

7. Covenants of the Underwriters. Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, the respective officers and directors of the Underwriters, and each person, if any, who controls any Underwriter 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 Registration Statement or any amendment thereof, any preliminary prospectus, the Disclosure Package or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus, or in any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, other than with respect to statements in the Registration Statement, 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 Underwriters through the Representative expressly for use therein, it being understood and agreed that the only information furnished by any such Underwriter consists of the information described in Section 8(b).

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its affiliates, its directors, its officers who sign the Registration Statement and each other person, if any, who controls the Company 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 to the Underwriters, but only with reference to information relating to the Underwriters furnished in writing by the Underwriters through the Representative to the Company expressly for use in the Registration Statement, any preliminary prospectus, the Disclosure Package, any issuer free writing prospectus, road show, or the Prospectus or any amendments or supplements thereto, it being understood and agreed that the only information furnished by any such Underwriters consists of the following information in the Disclosure Package and the Prospectus: (i) the names of the Underwriters on the cover page and (ii) the concession figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting.”

(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; but the omission so to promptly notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party provided that the party entitled to be so notified is not prejudiced by such delay to promptly notify. 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 Representative, in the case of parties indemnified pursuant to Section 8(a), and by the Company, 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 (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding, and (ii) does not include an admission of fault, culpability or a culpable failure to act, by or on behalf of an indemnified party.

(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 on the one hand and the Underwriters on the other hand from the offering of the Shares 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 on the one hand and of the Underwriters 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 on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total discounts and commissions received by the Underwriters, in each case as set forth in the Disclosure Package or herein, bear to the aggregate offering price of the Shares. The relative fault of the Company on the one hand and of the Underwriters 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 Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriters 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 Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter 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 Underwriters’ obligations to contribute pursuant to this Section 8(e) are several in proportion to the respective amount of Shares 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 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 Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors, or any other person controlling the Company and (iii) acceptance of and payment for any of the Shares.

9. Termination. This Agreement shall be subject to termination by notice given by the Underwriters to the Company, 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, either the New York Stock Exchange or The NASDAQ Stock Market LLC, or settlement of trading shall have been materially disrupted, (ii) trading of any securities of the Company 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 Shares on the terms and in the manner contemplated by this Agreement, the Disclosure Package or the Prospectus.

10. Default by an Underwriter. If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has

or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Disclosure Package, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

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 Underwriters because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters 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 Underwriters 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 000 X. Xxxxxx Xxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, Attention: Chief Financial Officer, or (b) if to the Underwriters, to Xxxxxx Xxxxxxx & Co. LLC, 0000 Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000, 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 Underwriters, the Company, 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 Underwriters of any of the Shares 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. 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.

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

17. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which they may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

18. Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, or the courts of the State of New York in each case located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation System as its agent to receive service of process or

other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York.

19. Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

20. 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.

		The exact share price and effective date may not be set forth on the table, in which case: · if the share price is between two share prices on the table or the effective date is between two effective dates on the table, the fundamental change conversion rate per Mandatory Convertible Preferred Share will be determined by straight-line interpolation between the fundamental change conversion rates per Mandatory Convertible Preferred Share set forth for the higher and lower share prices and the earlier and later effective dates, as applicable, based on a 365-day; · if the share price is in excess of $50.00 per share (subject to adjustment in the same manner as the share prices in the column headings of the table above as described in the Preferred Shares Preliminary Prospectus Supplement), then the fundamental change conversion rate per Mandatory Convertible Preferred Share will be the Minimum Conversion Rate, subject to adjustment as described in the Preferred Shares Preliminary Prospectus Supplement; and · if the share price is less than $2.00 per share (subject to adjustment in the same manner as the share prices in the column headings of the table above as described in the Preferred Shares Preliminary Prospectus Supplement), then the fundamental change conversion rate per Mandatory Convertible Preferred Share will be determined (a) as if the share price were equal to $2.00 and (b) if the effective date is between two effective dates on the table, using straight-line interpolation.

Conversion upon a Tax Event:		If at any time Issuer becomes obligated to pay or deliver additional amounts on the issued and outstanding Mandatory Convertible Preferred Shares in a tax event (as defined in the Preferred Shares Preliminary Prospectus Supplement), Issuer may, at its option, cause all, but not less than all, issued and outstanding Mandatory Convertible Preferred Shares to be automatically converted into a number of Common Shares equal to the fundamental change conversion rate determined as though the tax event conversion date (as defined in the Preferred Shares Preliminary Prospectus Supplement) were the effective date of a fundamental change and the “share price” in such transaction were the average of the volume-weighted average prices per Common Share over the 10 trading day period beginning on, and including, the second trading day immediately following the date on which Issuer provides notice of the tax event conversion.

Listing:		The Issuer will apply to list the Mandatory Convertible Preferred Shares on the NYSE under the symbol “NBR PR A”.

Ladies and Gentlemen:

The undersigned understands that Xxxxxx Xxxxxxx & Co. LLC (the “Representative”) propose to enter into an Underwriting Agreement (the “Common Shares Underwriting Agreement”) with Xxxxxx Industries Ltd., a Bermuda exempted company (the “Company”), providing for the public offering (the “Common Shares Public Offering”) by the several Underwriters, including the Representative (the “Underwriters”), of common shares, par value $0.001 per share, of the Company (the “Common Shares”). The undersigned also understands that the Representative proposed to enter into an Underwriting Agreement (the “Convertible Preferred Underwriting Agreement”) with the Company providing for the public offering (the “Convertible Preferred Public Offering” and, together with the Common Shares Public Offering, the “Offerings”) by the Underwriters of 6.00% series A mandatory convertible preferred shares, par value $0.001 per share (the “Convertible Preferred Shares”). The Convertible Preferred Shares will be convertible into a variable number of Common Shares. The Common Shares Public Offering and the Convertible Preferred Public Offering are not contingent on one another.

To induce the Underwriters that may participate in the Offerings to continue their efforts in connection with the Offerings, the undersigned hereby agrees that, without the prior written consent of the Representative on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 60 days after the date of the final prospectuses (the “Restricted Period”) relating to the Offerings (the “Prospectuses”), (1) 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 beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Shares (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to Common Shares or other securities acquired in open market transactions after the completion of the Offerings, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Shares or other securities acquired in such open market transactions, (b) transfers of Common Shares or any security convertible into Common Shares as a bona fide gift, or (c) distributions of Common Shares or any security convertible into Common Shares to limited partners or shareholders of the

Exhibit A-1

undersigned; provided that in the case of any transfer or distribution pursuant to clause (b) or (c), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Common Shares, shall be required or shall be voluntarily made during the Restricted Period, or (d) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Shares, provided that (i) such plan does not provide for the transfer of Common Shares during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Shares may be made under such plan during the Restricted Period. In addition, the undersigned agrees that, without the prior written consent of the Representative on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Common Shares or any security convertible into or exercisable or exchangeable for Common Shares. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Common Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Offerings. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Offerings actually occur depends on a number of factors, including market conditions. Each Offering will only be made pursuant to the Common Shares Underwriting Agreement or the Convertible Preferred Underwriting Agreement, as applicable, the terms of which are subject to negotiation between the Company and the Underwriters.

ANNEX 5(C)

OPINION OF XXXXXX X. XXXXXX

Each of Xxxxxx Industries, Inc., Xxxxxx International Finance Inc., Xxxxxx Drilling Technologies USA, Inc. and Xxxxxx Drilling Holdings Inc. (collectively, the “Selected Subsidiaries” and each, a “Selected Subsidiary”), has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction in which it is chartered or organized, with full corporate power and authority to own its properties and conduct its business as described in the Registration Statement, the Disclosure Package and the Prospectus, and is duly qualified to do business as a foreign corporation 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 Company and its subsidiaries, taken as a whole;

All outstanding shares of capital stock of the Significant Subsidiaries are owned by the Company 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 Company or a 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 Company or a Significant Subsidiary;

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 Company or any of its subsidiaries of a character required to be disclosed in the Registration Statement, the Disclosure Package or the Prospectus which is not disclosed in the Registration Statement, the Disclosure Package or the Prospectus as required or any contracts or other documents that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus or to be filed as exhibits to the Registration Statement that are not so described or filed; and

Neither the issue and sale of the Shares, the consummation of any other of the transactions contemplated by this Agreement and the Certificate of Designations, including the issuance of the Shares and the issuance of the Maximum Number of Common Shares issuable by the Company in accordance with the terms of the Certificate of Designations, nor the fulfillment of the terms thereof 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 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 or any of the Significant Subsidiaries of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Company or any of the Significant Subsidiaries, except such as would not, either singly or in the aggregate, have a material adverse effect upon the Company and its subsidiaries, taken as a whole, or prevent the Company from performing its obligations under this Agreement and the Certificate of Designations, including the issuance of the Shares and the issuance of the Maximum Number of Common Shares issuable by the Company in accordance with the terms of the Certificate of Designations, or (B) the respective charters, bylaws or other organizational documents of the Significant Subsidiaries (assuming that the relevant laws of the

Annex 5(C)-1

jurisdiction of organization of any Significant Subsidiary not organized in Texas or Delaware are the same as those of Texas).

Such counsel shall also state that it has no reason to believe that any part of the Registration Statement, when such part became effective, the Disclosure Package, as of the Applicable Time, or the Prospectus, 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 necessary in order to make the statements therein, other than with respect to statements in the Registration Statement, in the light of the circumstances under which they were made, not misleading (it being understood that such counsel need not express an opinion or comment with respect to the financial statements and the other financial information contained or incorporated by reference therein or excluded therefrom).

Annex 5(C)-2

ANNEX 5(D)-1

OPINION OF MILBANK, TWEED, XXXXXX & XxXXXX LLP

1. Xxxxxx Industries, Inc. is validly existing as a corporation in good standing under the laws of the State of Delaware.

2. The filing of the Final Prospectus pursuant to Rule 424(b)(2) has been made in the manner and within the time period required by Rule 424(b)(2) (without reference to Rule 424(b)(8)).

3. Each document filed pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and incorporated by reference in the Registration Statement, the Disclosure Package or the Final Prospectus appeared on its face to be appropriately responsive as of its filing date in all material respects to the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that we express no opinion and make no statement as to the financial statements and other financial and accounting information and data and management’s report on the effectiveness of internal control over financial reporting included or incorporated by reference therein.

4. Each of the Registration Statement, as of its most recent effective date, the Disclosure Package, as of the Applicable Time, and the Final Prospectus, as of the date thereof, appeared on their face to be appropriately responsive in all material respects to the applicable requirements of the Securities Act and the rules and regulations thereunder, except that we express no opinion and make no statement as to the financial statements and other financial and accounting information and data and management’s report on the effectiveness of internal control over financial reporting included or incorporated by reference therein. In rendering this opinion we take no responsibility for the accuracy, completeness or fairness of the statements made in the Registration Statement, the Disclosure Package or the Final Prospectus, except to the extent set forth in paragraph 8.

5. The Underwriting Agreement has been duly executed and delivered by the Company.

6. No consent, approval, authorization or order of any Governmental Authority (as defined below) is required for the consummation of the transactions contemplated by the Underwriting Agreement, except such as have been made or obtained prior to the date hereof or as may be required under federal or state securities or “blue sky” laws of any jurisdiction.

7. Neither the issue and sale of the Preferred Shares by the Company, nor the consummation of any of the other transactions contemplated in the Underwriting Agreement, nor the fulfillment of the terms of the Underwriting Agreement, results in a breach or violation of Applicable Law (as defined below), except such as would not, either singly or in the aggregate, have a material adverse effect on the Company and its subsidiaries, taken as a whole, or prevent the Company from performing its obligations under the Underwriting Agreement.

8. The statements in the Disclosure Package and the Final Prospectus under the caption titled “Certain U.S. Federal Income Tax Considerations” to the extent they constitute

Annex 5(C)-1

statements of law or legal conclusions are, subject to the limitations, qualifications, exceptions, and assumptions set forth therein, correct in all material respects.

9. The Company is not required to, and, immediately after giving effect to the offering and sale of the Preferred Shares and the application of the proceeds thereof as described in the Disclosure Package and the Final Prospectus, the Company will not be required to register as an investment company under the Investment Company Act of 1940, as amended.

The foregoing opinion in paragraph 8 above is limited to matters involving United States federal law, and we do not express any opinion as to the laws of any other jurisdiction. The foregoing opinion in paragraph 8 is based on the law in effect on the date hereof, including the United States Internal Revenue Code of 1986, as amended (the “Code”), and United States Treasury regulations (including proposed regulations) promulgated under the Code, the legislative history thereof, judicial decisions and administrative pronouncements and rulings of the United States Internal Revenue Service. Such laws are subject to change, possibly with retroactive effect, and we undertake no obligation to update such opinion or otherwise advise you if any such laws should change. Our opinion is not binding on the Internal Revenue Service or a court and, in particular due to the absence of authority addressing a closely comparable transaction, there can be no assurance that the Internal Revenue Service or a court will not adopt a position contrary to our opinion.

For purposes of the opinions rendered above, (i) “Applicable Law” means United States federal laws (other than the federal and state securities laws), the laws of the State of New York and those provisions of the General Corporation Law of the State of Delaware which in each case in our experience are normally applicable to transactions of the type contemplated by the Underwriting Agreement and (ii) “Governmental Authority” means any United States federal or State of New York administrative, judicial or other governmental agency, authority, tribunal or body.

We express no opinion as to matters governed by any laws other than the laws of the State of New York, the General Corporation Law of the State of Delaware and United States federal laws. The opinions contained herein are rendered to you and are solely for your benefit in connection with the closing under the Underwriting Agreement of the sale of the Preferred Shares occurring today and may not be used, quoted, relied upon or otherwise referred to by any other person or for any other purpose without our express written consent in each instance. We disclaim any obligation to update anything herein for events occurring after the date hereof.

NEGATIVE ASSURANCE LETTER

MILBANK, TWEED, XXXXXX & XxXXXX LLP

(i) the Registration Statement (other than the financial statements and schedules and other financial and accounting information and data and management’s report on the effectiveness of internal control over financial reporting, as to which we express no belief and make no statement), ) as of its most recent effective date, contained an untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading;

Annex 5(D)-2-1

ANNEX 5(E)

OPINION OF XXXXXXX XXXX & XXXXXXX LIMITED

1. The Company is duly incorporated and existing under the laws of Bermuda in good standing (meaning solely that it has not failed to make any filing with any Bermuda governmental authority, or to pay any Bermuda government fee or tax, which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda).

2. The Company has the necessary corporate power and authority to conduct its business and to own, lease and operate its property as described in the Registration Statement, the Disclosure Package and the Prospectus.

3. The Company has the necessary corporate power and authority to enter into and perform its obligations under the Agreement, including, for the avoidance of doubt, the issuance of the Preferred Shares and the issuance of the Common Shares in accordance with the terms of the Agreement and the Certificate of Designations. The execution and delivery of the Agreement and the performance by the Company of its obligations thereunder, including the issuance and sale of the Preferred Shares and the issuance of the Common Shares in accordance with the terms of the Preferred Shares and the Certificate of Designations, will not violate the memorandum of association or bye-laws of the Company nor any applicable law, regulation, order or decree in Bermuda.

4. The Company has taken all corporate action required to authorise its execution, delivery and performance of the Agreement and the issuance of the Preferred Shares and the issuance of the Common Shares in accordance with the terms of the Certificate of Designations. The Agreement has been duly executed and delivered by or on behalf of the Company, and constitutes the valid, binding and enforceable obligation of the Company in accordance with the terms thereof.

5. No order, consent, approval, licence, authorisation or validation of or exemption by any government or public body or authority of Bermuda or any sub-division thereof is required to authorise or is required in connection with the execution, delivery, performance and enforcement of the Agreement or for the issuance of the Preferred Shares and the issuance of the Common Shares in accordance with the terms of the Certificate of Designations, except such as have been duly obtained in accordance with Bermuda law.

6. It is not necessary or desirable to ensure the enforceability in Bermuda of the Agreement that they be registered in any register kept by, or filed with, any governmental authority or regulatory body in Bermuda. However, to the extent that Agreement creates a charge over assets of the Company, it may be desirable to ensure the priority in Bermuda of the charge that it be registered in the Register of Charges in accordance with Section 55 of the Companies Xxx 0000. On registration, to the extent that Bermuda law governs the priority of a charge, such charge will have priority in

Annex 5(E)-1

Bermuda over any unregistered charges, and over any subsequently registered charges, in respect of the assets which are the subject of the charge. A registration fee of $665 will be payable in respect of the registration.

While there is no exhaustive definition of a charge under Bermuda law, a charge includes any interest created in property by way of security (including any mortgage, assignment, pledge, lien or hypothecation). As the Agreement is governed by the Foreign Laws, the question of whether they create such an interest in property would be determined under the Foreign Laws.

7. The Agreement will not be subject to ad valorem stamp duty in Bermuda and no registration, documentary, recording, transfer or other similar tax, fee or charge is payable in Bermuda in connection with the execution, delivery, filing, registration or performance of the Agreement other than as stated in paragraph 6 hereof.

8. The Preferred Shares have been duly authorized by the Company and when issued and paid for in accordance with the Agreement, will be validly issued, fully paid and non-assessable (which term means when used herein that no further sums are required to be paid by the holders thereof in connection with the issue of such shares), and the issuance of such Shares will not be subject to any preemptive rights or similar rights.

9. The Common Shares have been duly authorized and reserved for issuance and, when issued in accordance with the terms of the Preferred Shares and the Certificate of Designations, will be validly issued, fully paid and non-assessable (which term means when used herein that no further sums are required to be paid by the holders thereof in connection with the issue of such shares), and will not be subject to any preemptive rights or similar rights.

10. Based solely on a search of the public records in respect of the Company maintained at the offices of the Registrar of Companies at [TIME] on [ ] May 2018, the authorized share capital of the Company is US$[ ] divided into [ ]shares of which [ ] are Common Shares and [ ] are preferred shares, par value US$0.001 each.

11. Based solely upon a review of the register of members of the Company prepared by Computershare Shareholder Services Inc., the branch registrar of the Company, on [ ] May 2018, there are [ ] issued and outstanding Common Shares of the Company, all of which are validly issued, fully paid and non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection with the issuer thereof) and such shares are not subject to any statutory pre-emptive or similar rights.

12. The statements set forth in the Disclosure Package and the Prospectus under the caption “Description of Authorized Share Capital,” “Description of the Series A Preferred Shares” and “Certain Bermuda Tax Considerations” to the extent they constitute statements of Bermuda law or summaries of Shares, are accurate in all material respects.

Annex 5(E)-2

13. The choice of the Foreign Laws as the governing law of the Agreement is a valid choice of law and would be recognised and given effect to in any action brought before a court of competent jurisdiction in Bermuda, except for those laws (i) which such court considers to be procedural in nature; (ii) which are revenue or penal laws or (iii) the application of which would be inconsistent with public policy, as such term is interpreted under the laws of Bermuda.
