Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Company and the Issuer, and each of their respective directors, officers who signs a Registration Statement and each person, if any, who controls either of the Company or the Issuer within the meaning of the Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which such indemnified party may become subject, under the Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter or is otherwise permitted in Section 9(d) hereof), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any part of the Registration Statement, any Statutory Prospectus, the Final Prospectus, or any Issuer Free Writing Prospectus, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the

Registration Statement, any Statutory Prospectus, the Final Prospectus, or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company and the Issuer by such Underwriter through the Representatives expressly for use therein; and to reimburse such indemnified party for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by such indemnified party in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and the Issuer hereby acknowledges that the only information that the Underwriters through the Representatives have furnished to the Company and the Issuer expressly for use in the Final Prospectus are the statements described in Section 9(a) above. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the failure to so notify the indemnifying party will not relieve such indemnifying party from any liability which it may have to any indemnified party under the indemnity agreement contained in this Section 9 except to the extent it is materially prejudiced (through the forfeiture of substantive rights and defenses) as a result of such failure and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party otherwise than under the provisions of this Section 9. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties (such counsel to be selected by the Representatives in the case of Sections 9(a) and 9(e) hereof); provided, further, that the Company and the Issuer shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons, which firm shall be selected by the Representatives. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)) representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, 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 against any loss, claim, damage, liability or expense 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 this Section 9, 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 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days before such settlement is entered into and (iii) 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, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

(e) Contribution. If the indemnification provided for in this Section 9 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Issuer, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company and the Issuer, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Issuer, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (after deducting discounts and commissions to the Underwriters but before deducting expenses) received by the Company and the Issuer bear to the total purchase discounts and commissions received by the Underwriters. The relative fault of the Company and the Issuer, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Issuer, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in this Section 9, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in this Section 9 with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9(e); provided, however, that no additional notice shall be required with respect to any action for which notice has been given under this Section 9 for purposes of indemnification.

The Company, the Issuer and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9(e).

Notwithstanding the provisions of this Section 9(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public exceeds the amount of any damages which 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 of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9(e) are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9(e), each director, officer, selling agent and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director and officer of the Company or the Issuer, and each person, if any, who controls the Company or the Issuer within the meaning of the Act and the Exchange Act, shall have the same rights to contribution as the Company.

10. Termination of This Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company and the Issuer if at any time: (i) trading or quotation in any of the Company’s or the Issuer’s securities shall have been suspended or materially limited by the Commission, (ii) trading in securities generally on either the NASDAQ Stock Market or the New York Stock Exchange shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iv) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities in the manner and on the terms described in the General Disclosure Package or to enforce contracts for the sale of securities; (v) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (vi) the Company or the Issuer shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may interfere materially with the conduct of the business and operations of the Company or the Issuer regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 10 shall be without

liability on the part of (a) the Company or the Issuer to any Underwriter, except that the Company and the Issuer shall be obligated to reimburse the expenses of the Underwriters pursuant to Sections 5(h) and 8 hereof, (b) any Underwriter to the Company and the Issuer, or (c) any party hereto to any other party except that the provisions of Section 9 hereof shall at all times be effective and shall survive such termination.

11. Survival. The respective indemnities, agreements, representations, warranties and other statements of each of the Company and the Issuer and their respective officers and the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Company, the Issuer or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

12. Notices. All communications hereunder shall be in writing and shall be mailed, hand delivered, couriered or facsimiled and confirmed to the parties hereto as follows:

Any party hereto may change the address or facsimile number for receipt of communications by giving written notice to the others.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Section 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any purchaser of the Securities as such from any of the Underwriters merely by reason of such purchase.

14. Authority of the Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

16. Governing Law Provisions. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(a) 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 or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (a “Related Judgment”) as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related 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 Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Related Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. Each of the Company and the Issuer has irrevocably appointed National Corporate Research, Ltd. (“NCR”), located at ▇▇ ▇▇▇▇ ▇▇^▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified Court. Service of any process, summons, notice or document sent to NCR in any manner permitted by applicable law shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

(b) 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.

(c) Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase U.S. dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligations of the each of the Company and the Issuer in respect of any sum due from it to any Underwriter shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Underwriter hereunder, each of the Company and the Issuer agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the U.S. dollars so purchased are

greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company or the Issuer, as the case may be, (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Underwriter hereunder.

17. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities hereunder on the Closing Date, and the aggregate principal amount of Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the aggregate principal amount of Securities that the Underwriters are obligated to purchase on the Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Securities that such defaulting Underwriters agreed but failed to purchase on the Closing Date. If any Underwriter or Underwriters so default and the principal amount of Securities with respect to which such default or defaults occur exceeds 10% of the aggregate principal amount of Securities that the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to the Representatives, the Company and the Issuer for the purchase of such Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Issuer, except as provided in Section 11. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 17. Nothing herein will relieve a defaulting Underwriter from liability for its default.

18. No Advisory or Fiduciary Responsibility. Each of the Company and the Issuer acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction among the Company, the Issuer and the several Underwriters, and each of the Company and the Issuer is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or the Issuer or any of their respective affiliates, shareholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Issuer with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Issuer on other matters) or any other obligation to the Company or the Issuer except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Issuer and that the several Underwriters have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and each of the Company and the Issuer has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

19. Taxes. All payments to be made by the Company and/or the Issuer under this Agreement (including, for purposes of this provision, to any relevant extent, the difference between the purchase price paid by the Underwriters for the Securities and the offering price of the Securities) shall be paid free and clear of and without deduction or withholding for or on account of, any present or future taxes, levies or imposts by The Netherlands or the United Kingdom or by any department, agency or other political subdivision or taxing authority thereof or therein, and all interest, penalties or similar liabilities with respect thereto (collectively, “Taxes”). If any Taxes are required by law to be deducted or withheld in connection with such payments, the Company or the Issuer, as the case may be, will increase the amount paid so that the full amount of such payment is received by the Underwriters. All fees and amounts payable by the Company or the Issuer to the Underwriters under this Agreement are exclusive of any value added tax or any similar taxes (“VAT”). If the transactions described in this Agreement are subject to VAT, the Company or the Issuer, as the case may be, will pay the Underwriters the applicable VAT.

20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Each of the Company and the Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Company or the Issuer may have against the several Underwriters with respect to any breach or alleged breach of fiduciary duty with respect to transactions contemplated by this Agreement.

Dutch Counsel to the Issuer

1.1	Each Company has been incorporated and exists as a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) (in the case of the Issuer) or a limited liability company (naamloze vennootschap) (in the case of the Guarantor).

1.2

(a)

Each Company has the corporate power to enter into and perform its obligations under the Agreements and, in the case of the Issuer, to issue and perform its obligations under the Notes.

(b)

Each Company has taken all necessary corporate action to authorise its entry into and performance of its obligations under the Agreements and, in the case of the Issuer, its issue and performance of its obligations under the Notes.

(c)

Each Company has validly signed the Agreements and, in the case of the Issuer, the Notes.

1.3

(a)

No Company requires any licence, dispensation, recognition or other governmental consent for its entry into and performance of the Agreements or, in the case of the Issuer, for its issue and performance of the Notes except for the purpose of complying with the assumption in paragraph 1.2(a).

(b)

There are no registration, filing or similar governmental formalities required to ensure the validity, binding effect on and enforceability against each Company of the Agreements and, in the case of the Issuer, the Notes.

1.4	The entry into and performance of its obligations under the Agreements, and, in the case of the Issuer, its issue and performance of the Notes, by each Company do not violate Dutch law or its articles of association.

1.5	Neither Company is entitled to immunity from legal proceedings nor are its assets immune from execution.

In proceedings in a New York Court, New York Law determines the validity, binding effect on and enforceability against each Company of the Jurisdiction Clause included in each of the Agreements and the Notes.

A judgment rendered by a New York Court will not be recognised and enforced by the Dutch courts. However, if a person has obtained a final and conclusive judgment for the payment of money rendered by a New York Court which is enforceable in New York and files his claim with the competent Dutch court, the Dutch court will generally give binding effect to the judgment insofar as it finds that (i) the jurisdiction of the New York Court has been based on grounds which are internationally acceptable, (ii) proper legal procedures have been observed, and (iii) the judgment does not contravene Dutch public policy.

1.8

(a)

Any payments made under the Notes or the Agreements will not be subject to withholding or deduction for, or on account of, any Dutch Taxes.

5.

C-2-1

6. The statements set forth under the headings “Description of Debt Securities,” “Description of Guarantees” and “Description of the Notes” in the Final Prospectus and in the General Disclosure Package, insofar as such statements purport to summarize certain provisions of the Securities and the Indenture, accurately summarize such provisions in all material respects.

7. The issuance and sale of the Securities to the Underwriters by the Company and the Issuer pursuant to the Underwriting Agreement does not, and the performance by the Company and the Issuer of their respective obligations under the Transaction Documents in accordance with their terms will not (i) require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States of America or the State of New York (other than such as may be required under United States federal securities laws, any state securities or blue sky laws or the rules and regulations of the Financial Industry Regulatory Authority, as to which we express no opinion), (ii) result in a breach of, or constitute a default under, any of the agreements of the Company identified in Exhibit A hereto or (iii) result in a violation of any United States federal or New York State law or published rule or regulation (other than state securities or blue sky laws and anti-fraud laws, orders, rules and regulations, as to which we express no opinion), except in the case of clause (ii) and (iii) for such breaches, conflicts or violations as would not, individually or in the aggregate, have a Material Adverse Change.

8. No registration of either the Company or the Issuer under the U.S. Investment Company Act of 1940, as amended, is required for the offer and sale of the Securities and the application of the net proceeds thereof in the manner contemplated by the Underwriting Agreement and the Final Prospectus.

9. Under the laws of the State of New York relating to submission to jurisdiction, each of the Company and the Issuer, pursuant to Section 16 of the Underwriting Agreement, has (a) validly and irrevocably submitted to the personal jurisdiction of any New York State or U.S. federal court located in the City and County of New York, in any action arising out of or related to the Underwriting Agreement, (b) to the fullest extent permitted by applicable law, validly and irrevocably waived any objection to the venue of a proceeding in any such court, and (c) validly appointed NCR as its initial authorized agent for the purpose described in Section 16 of the Underwriting Agreement; and service of process effected in the manner set forth in Section 16 of the Underwriting Agreement will be effective to confer valid personal jurisdiction over the Company and the Issuer in any such action.

We have reviewed the Registration Statement, the General Disclosure Package and the Final Prospectus and have participated in conferences with officers and other representatives of the Company and the Issuer, with representatives of the Company’s independent registered public accounting firm and with your representatives and your counsel, at which the contents of the Registration Statement, the General Disclosure Package, the Final Prospectus and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the General Disclosure Package or the Final Prospectus, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the General Disclosure Package and the Final Prospectus involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the General Disclosure Package and the Final Prospectus (except to the extent stated in paragraphs 5 and 6 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that nothing came to our attention that caused us to believe that:

C-2-2

(1)

the Registration Statement, as of the latest Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(2)

the General Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(3)

the Final Prospectus, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case we have not been asked to, and do not, express any belief with respect to (a) the financial statements and schedules or other financial, accounting or statistical information contained or included or incorporated by reference therein or omitted therefrom, (b) representations and warranties and other statements of fact contained in the exhibits to the Registration Statement or to documents incorporated by reference therein or (c) that part of the Registration Statement that constitutes the Forms T-1.

The opinions set forth above are limited in all respects to matters of the laws of the State of New York and applicable federal law of the United States, each as in effect on the date hereof. We have relied as to matters of Dutch law upon the opinion of De Brauw Blackstone Westbroek N.V. furnished to you pursuant to the Underwriting Agreement.

Such counsel’s opinion shall also be subject to other qualifications as reasonably agreed to between such counsel and the Representatives.

SCHEDULE C-3

Form of LyondellBasell In-House Opinion

1. Each of the Significant Subsidiaries organized under the laws of a U.S. jurisdiction has been duly organized and is validly existing under the laws of its jurisdiction of organization, with power and authority (corporate, limited liability company or limited partnership) under such laws to own its properties and conduct its business as described in the General Disclosure Package, the Final Prospectus and the documents incorporated by reference in each of them, and has been duly qualified for the transaction of business and is in good standing under the laws of each jurisdiction in which it owns or leases properties, or conducts any business, so as to require such qualification, other than where the failure to be so qualified or in good standing would not result in a Material Adverse Change; and all the outstanding shares of capital stock or other ownership interests of each such Significant Subsidiary have been duly authorized and validly issued, are fully paid and non-assessable, and (except (i) any Liens permitted under the indentures dated as of April 9, 2012, November 14, 2011 and July 16, 2013, relating to the Company’s 5.000% Senior Notes due 2019 and 5.750% Senior Notes due 2024; the Company’s 6.000% Senior Notes due 2021; and the 4.000% Guaranteed Notes due 2023 and 5.250% Guaranteed Notes due 2043 issued by LYB International Finance B.V. and guaranteed by the Company, respectively, and (ii) as otherwise set forth in the General Disclosure Package, the Final Prospectus and the documents incorporated by reference in each of them) are owned, directly or indirectly by the Company, free and clear of all consensual liens, encumbrances, equities and similar claims.

2. Other than as set forth or contemplated in the General Disclosure Package, the Final Prospectus and the documents incorporated by reference in each of them, to the best of my knowledge, there are no legal or governmental investigations, actions, suits or proceedings pending or threatened or contemplated against the Company or any of its subsidiaries or any of their respective properties or to which the Company or any of its subsidiaries is or may be a party or to which any property of the Company or its subsidiaries is or may be the subject which, if determined adversely to the Company or its subsidiaries, could individually or in the aggregate reasonably be expected to result in a Material Adverse Change.

3. I do not know of any statutes, regulations, contracts or other documents that would be required by the Act to be disclosed in the Registration Statement, the General Disclosure Package and the Final Prospectus that are not so disclosed (including by way of incorporation by reference).

4. To the best of my knowledge, neither the Company nor the Issuer is, and with the giving of notice or lapse of time or both would not be, in violation of or in default under any agreement or instrument to which the Company or the Issuer, as the case may be, is a party or by which it or any of its properties is bound, except for violations and defaults which, individually and in the aggregate, would not reasonably be expected to result in a Material Adverse Change.

5. The sale of the Securities to the Underwriters pursuant to the Underwriting Agreement does not, and the performance by the Company and the Issuer of their respective obligations under the Transaction Documents will not, (a) conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any agreement or instrument known to me to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or its subsidiaries is subject, (b) result in a violation of any applicable law or statute or any order, rule

C-3-1

or regulation of any court or governmental agency or body having jurisdiction over the Company, its subsidiaries or any of their respective properties, or (c) result in the imposition or creation of (or the obligation to create or impose) a Lien under any agreement or instrument to which the Company or the Issuer is a party or by which the Company, the Issuer or their respective property is bound; except where the conflict, breach, default, violation, or the imposition or creation of a Lien would not reasonably be expected to result in a Material Adverse Change, and in the case of (b) where I express no opinion with respect to state securities laws or the antifraud provisions of the United States securities laws.

6. Except as disclosed in the General Disclosure Package, the Final Prospectus and the documents incorporated by reference in each of them, (a) the Company and the Issuer, and, to the best of my knowledge, each other subsidiary of the Company, owns, possesses or has obtained all licenses, permits, certificates, consents, orders, approvals and other authorizations from, and has made all declarations and filings with, all federal, state, local and other governmental authorities (including foreign regulatory agencies), all self-regulatory organizations and all courts and other tribunals, domestic or foreign, necessary to own or lease, as the case may be, and to operate its properties and to carry on its business as conducted as of the date hereof except such as could not reasonably be expected to result in a Material Adverse Change; (b) to the best of my knowledge, none of the Company or any of its subsidiaries has received any actual notice of any proceeding relating to revocation or modification of any such license, permit, certificate, consent, order, approval or other authorization which, if determined adversely to the Company or any of its subsidiaries could reasonably be expected to result in a Material Adverse Change; and (c) to the best of my knowledge, each of the Company and its subsidiaries is in compliance with all laws and regulations relating to the conduct of its business as conducted as of the date hereof, except where the failure to so comply could not reasonably be expected to result in a Material Adverse Change.

7. The Registration Statement and the Final Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission under the Act, except for the financial statements, financial statement schedules and other financial data included or incorporated by reference in or omitted from either of them, as to which we express no opinion.

8. Except as disclosed in the General Disclosure Package and the Prospectus, to the best of my knowledge, there are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by the Underwriting Agreement, except for such rights as have been duly waived.

In addition, I have participated in conferences with officers and other representatives of the Company and the Issuer, and persons under my direction or control have participated in conferences with officers and other representatives of the Company and the Issuer, representatives of the independent accountants of the Company, with your representatives and your counsel at which conferences the contents of the General Disclosure Package, the Final Prospectus, portions of certain of the documents incorporated by reference in each of them and related matters were discussed. Although I did not independently verify such information and am not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the General Disclosure Package, the Final Prospectus and the documents incorporated by reference in each of them, on the basis of the foregoing (relying as to materiality, to the extent I deem reasonable, upon officers and other representatives of the Company and the

C-3-2

Issuer), no facts have come to my attention to lead me to believe that (a) the General Disclosure Package, including the documents incorporated by reference therein (other than the financial statements, the notes thereto and the auditor’s reports thereon, management’s report on internal control over financial reporting and the other financial and accounting data contained therein or omitted therefrom), at the time of execution of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (b) the Final Prospectus, including the documents incorporated by reference therein (other than the financial statements, the notes thereto and the auditor’s reports thereon, management’s report on internal control over financial reporting and the other financial and accounting data contained therein or omitted therefrom), as of the date thereof or the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.
