        These fees are calculated based on the number of issuances and amount of securities to be offered and, accordingly, cannot be estimated at this time.

Item 15.    Indemnification of Directors and Officers.

        Under our operating agreement, we must indemnify our manager and its and our officers and directors to the fullest extent permitted by law, against liabilities, costs and expenses incurred by our manager or these other persons. We must provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud or willful misconduct. We also must provide this indemnification for criminal proceedings unless our manager or these other persons acted with knowledge that their conduct was unlawful. Thus, our manager or these other persons could be indemnified for its negligent or grossly negligent acts if they meet the requirements set forth above. Any provision that includes indemnification for liabilities arising under the Securities Act is, according to the SEC, contrary to public policy and therefore unenforceable.

        Specifically, we will indemnify the following persons, in most circumstances, to the fullest extent permitted by law, from and against all losses, claims, damages or similar events:

•

our manager;

•

any departing manager;

•

any person who is or was a director, officer, fiduciary, trustee, manager or managing member of us or any of our subsidiaries (including the Issuers), our manager or any departing manager;

•

any person who is or was serving as a director, officer, fiduciary, trustee, manager or managing member of another person owing a fiduciary duty to us or any of our subsidiaries at the request of our manager or any departing manager;

•

any person who controls our manager; or

•

any person designated by our board.

        Any indemnification under the provisions of our operating agreement will only be out of our assets. Unless it otherwise agrees, our manager will not be personally liable for, or have any obligation to contribute or loan funds or assets to us to enable us to effectuate, indemnification.

II-1

        Subject to any terms, conditions or restrictions set forth in an operating agreement or limited liability company agreement, Section 18-108 of the Delaware Limited Liability Company Act empowers a Delaware limited liability company to indemnify and hold harmless any member or other persons from and against all claims and demands whatsoever.

        The Limited Liability Company Agreement of Niska US provides that none of the members, managers or officers of Niska US are liable to it for any act or omission done or omitted in good faith, unless such act or omission constitutes gross negligence, willful misconduct or a breach of the Limited Liability Company Agreement of Niska US. In addition, the Limited Liability Company Agreement of Niska US requires Niska US to indemnify any of its members, managers or officers to the fullest extent permitted by law against any loss, liability, damage, judgment, demand, claim, cost or expense incurred by or asserted against such persons, including, reasonable attorney's fees and disbursements incurred in defense thereof, arising out of any act or omission unless such act or omission constitutes bad faith, gross negligence or willful misconduct on the part of such person.

        The Certificate of Incorporation of US Finco provides that a director or officer will not be liable to it or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability for:

•

any breach of such director or officer's duty of loyalty to the it or its stockholders;

•

for acts or omissions not in good faith or which involved intentional misconduct or a knowing violation of the law;

•

under section 174 of the Delaware General Corporation Law, or the DGCL, for unlawful payment of dividends or improper redemption of stock; or

•

for any transaction from which the director or officer derived an improper personal benefit.

        In addition, the bylaws of US Finco provide that it will indemnify, and advance expenses to, any officer or director to the fullest extent authorized by the DGCL and that US Finco may maintain insurance on behalf of its officers and directors against expense, liability or loss asserted incurred by them in their capacities as officers and directors.

        Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement in connection with specified actions, suits and proceedings whether civil, criminal, administrative, or investigative, other than a derivative action by or in the right of the corporation, if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses, including attorneys' fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation's certificate of incorporation, bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

        Each of Niska Canada and Canada Finco is incorporated under the Alberta Business Corporations Act, or the ABCA. Under the ABCA, each of Niska Canada and Canada Finco may indemnify an individual who is or was a director or officer of such corporations, or who is or was a director or officer of another corporation, of which such corporations are or were a shareholder or creditor, at the corporations' request, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the director or officer in respect of any civil,

II-2

criminal or administrative action or proceeding, in which such eligible party is involved because of that association with such corporations or the other entity.

        However, indemnification is prohibited under the ABCA if: (i) such eligible party did not act honestly and in good faith with a view to such corporations' respective best interests (or the best interests of the other entity, as the case may be); and (ii) in the case of a criminal or administrative proceeding that is enforced by a monetary penalty, such eligible party did not have reasonable grounds for believing that such person's conduct was lawful.

        Subject to the foregoing, each of Niska Canada and Canada Finco may, with the approval of the Court of Queen's Bench of Alberta, indemnify or pay the expenses of an eligible party in respect of an action brought against the eligible party by such corporations or on such corporations' behalf to which the eligible party is made a party by reason of being or having been a director or officer of such corporations (or the other entity as the case may be).

        The ABCA provides that each of Niska Canada and Canada Finco may purchase and maintain insurance for the benefit of an eligible party (or their heirs and personal or other legal representatives of the eligible party) against any liability that may be incurred by reason of the eligible party being or having been a director or officer, or in an equivalent position of such corporations or that of an associated corporation, except when the liability relates to the person's failure to act honestly and in good faith with a view to the best interests of such corporations' or an associate corporation, as applicable.

        The by-laws of each of Niska Canada and Canada Finco provide that, subject to the limitations in the ABCA and except in respect of an action by or on behalf of such corporations or body corporate to procure a judgment in its favor, each of the corporations shall indemnify a director or officer of the corporation, a former director or officer of the corporation or a person who acts or acted at the corporation's request as a director or officer of a body corporate of which the corporation is or was a shareholder or creditor, and his heirs and legal representatives, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he is made a party by reason of being or having been a director or officer of the Corporation or body corporate, if: (i) he acted honestly and in good faith with a view to the best interests of the Corporation, and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful.

        The by-laws of each of Niska Canada and Canada Finco provide that such corporations shall, subject to the approval of the Court of Queen's Bench of Alberta, indemnify such officers and directors in respect of an action by or on behalf of such corporations or a body corporate to procure a judgment in its favor, to which he is made a party by reason of being or having been a director or an officer of the such corporations or body corporate, against all costs, charges and expenses reasonably incurred by him in connection with such action if he fulfills the above conditions.

        The by-laws of each of Niska Canada and Canada Finco further provide that such officers and directors shall be entitled to indemnity from such corporations in respect of all costs, charges and expenses reasonably incurred by him in connection with the defense of any civil, criminal or administrative action or proceeding to which he is made a party by reason of being or having been a director or officer of such corporations or body corporate, if the person seeking indemnity: (i) was substantially successful on the merits of his defense of the action or proceeding; and (ii) fulfills the above conditions.

        (2)   Financial Statement Schedules

Item 17.    Undertakings.

        (1)   The undersigned registrant hereby undertakes:

        (a)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

          (i)  To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

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

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

provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

        (b)   That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (c)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

        (d)   That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

          (i)  Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

         (ii)  Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information

II-4

required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

        (e)   That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

          (i)  Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

         (ii)  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

        (iii)  The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

        (iv)  Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

        (2)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (3)   Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of any registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

II-5

        (4)   The undersigned registrant hereby undertakes that:

        (a)   For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

        (b)   For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (5)   The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act ("Act") in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.

Exhibit 5.1

December 19, 2014

Niska Gas Storage Partners LLC

170 Radnor Chester Road, Suite 150

Radnor, PA 19087

Ladies and Gentlemen:

We have acted as counsel for Niska Gas Storage Partners LLC, a Delaware limited liability company (the “Company”), with respect to the preparation of the Registration Statement on Form S-3 (Reg. No. 333-200004) (the “Registration Statement”) filed by the Company, Niska Gas Storage US, LLC, a Delaware limited liability company, Niska Gas Storage US Finance Corp., a Delaware corporation, Niska Gas Storage Canada ULC, an Alberta unlimited liability corporation and Niska Gas Storage Canada Finance Corp., an Alberta corporation (collectively, the “Issuers”), and certain other subsidiaries identified on Schedule I hereto (together with the Issuers, the “Guarantors”), with the Securities and Exchange Commission (the “Commission”) in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale, from time to time, pursuant to Rule 415 under the Securities Act.

(1)by the Company, of common units representing limited liability company interests in the Company (the “Primary Units”);

(2)by any Issuer or any combination of the Issuers, of debt securities of such Issuer or Issuers, which may either be senior or subordinated and may be issued in one or more series, consisting of debentures, notes, bonds or other evidences of indebtedness (the “Debt Securities”);

(3)by any Issuer or combination of the Issuers, of units consisting of one or more Debt Securities or Primary Units or any combination of such securities (the “Units”);

(4)by any Guarantor or combination of the Guarantors, of guarantees of the Debt Securities (the “Guarantees” and, together with the Primary Units, the Debt Securities and the Units, the “Primary Securities”); and

(5)by the unitholder named as the selling unitholder in the Registration Statement, of up to 16,304,745 common units representing limited liability company interests in the Company (the “Secondary Units” and, together with the Primary Securities, the “Securities”).

Vinson & Elkins LLP Attorneys at Law Abu Dhabi  Austin  Beijing  Dallas  Dubai  Hong Kong  Houston  London Moscow  New York  Palo Alto  Riyadh  San Francisco  Tokyo  Washington 1001 Fannin Street, Suite 2500 Houston, TX 77002-6760 Tel +1.713.758.2222  Fax +1.713.758.2346  www.velaw.com

We have also participated in the preparation of the Prospectus (the “Prospectus”) contained in the Registration Statement. The Primary Securities will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in supplements (each, a “Prospectus Supplement”) to the Prospectus.

In rendering the opinions set forth below, we examined and relied upon the Registration Statement, the Prospectus, the form of Senior Indenture (the “Senior Indenture”) filed as an exhibit to the Registration Statement, the form of Subordinated Indenture (the “Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”) filed as an exhibit to the Registration Statement, originals or copies, certified or otherwise identified to our satisfaction, of such certificates, statutes, documents, instruments, resolutions and records of the Guarantors, and communications with officers of the Guarantors. In addition, we have reviewed such questions of law as we considered necessary or appropriate.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies, that the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and the Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement and the applicable Prospectus Supplement, if any.

For the purposes of rendering the opinions set forth below, we have made the following assumptions:

(1)the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective;

(2)in the case of an offering of Primary Securities, that a Prospectus Supplement will have been prepared and filed with the Commission describing the Securities offered thereby;

(3)each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine;

(4)each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete;

(5)the Indentures, together with any supplemental indentures relating to a series of Debt Securities to be issued under either of the Indentures, and a unit

2

agreement, if applicable, relating to Units to be issued, will each be duly authorized and validly executed and delivered by the parties thereto;

(6)the Guarantors, at the time of issuance and sale of any Primary Securities, will be duly organized, validly existing and in good standing under the laws of their respective jurisdictions;

(7)at the time of the issuance of any Primary Securities, the applicable Guarantors will have the necessary organizational power and authority to issue such Primary Securities;

(8)a definitive purchase, underwriting or similar agreement with respect to any Primary Securities offered will have been authorized and validly issued and delivered by the issuers of such Primary Securities and the other parties thereto; and

(9)any Primary Securities issuable upon conversion, exchange or exercise of any Primary Security being offered will be duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange or exercise.

Based on the foregoing, we are of the opinion that:

(1)the Primary Units will be duly authorized, validly issued, fully paid and non-assessable when (a) the Company has taken all necessary action to duly authorize and approve the issuance of such Primary Units and the limited liability company interests represented thereby, the terms of the offering thereof and related matters and (b) the Primary Units have been issued and delivered in accordance with the terms of the applicable definitive purchase, underwriting or similar agreement approved by the Company upon payment of the consideration thereof or provided for therein;

(2)the Debt Securities and, if applicable, the Guarantees, will be duly authorized and validly issued and will constitute valid and legally binding obligations of the Issuer or Issuers issuing such Debt Securities and the Guarantors issuing such Guarantees, as applicable, enforceable against such Issuer or Issuers and the Guarantor or Guarantors, as applicable, in accordance with their terms, except as such enforcement is subject to any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and to general equitable principles (regardless of whether enforcement is sought in a proceeding in equity or at law) when (a) the applicable Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, (b) such Issuer or Issuers and Guarantor or Guarantors, as applicable, have taken all necessary action to duly authorize and approve

3

the issuance and terms of the Debt Securities, and, if applicable, the Guarantees and the terms of the offering thereof and related matters, (c) the terms of the Debt Securities and, if applicable, the Guarantees, and their issuance and sale have been duly established in conformity with the applicable Indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon such Issuer or Issuers and Guarantor or Guarantors, as applicable, and so as to comply with any requirements or restrictions imposed by any court or governmental body having jurisdiction over the such Issuer or Issuers and Guarantor or Guarantors, as applicable, and (e) the Debt Securities (which may include the related Guarantees) have been duly executed, authenticated, issued and delivered in accordance with the applicable Indenture and the applicable definitive purchase, underwriting or similar agreement upon payment of the consideration for the Debt Securities as provided for therein; and

(3)the Secondary Units have been duly authorized and validly issued and are fully paid and non-assessable.

Our opinion is qualified in the following respects:

(1)we express no opinions concerning (a) the validity or enforceability of any provisions contained in the Indentures that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law or (b) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws;

(2)the opinions expressed herein are limited in all respects to the federal laws of the United States of America, the General Corporation Law of the State of Delaware, the Delaware Limited Liability Company Act, the Delaware Revised Uniform Limited Partnership Act and the Constitution of the State of Delaware (including all applicable statutory provisions and reported judicial decisions interpreting those laws) and the laws of the State of New York, and we are expressing no opinion as to the effect of the laws of any other jurisdiction, domestic or foreign;

(3)we express no opinion with respect to the validity or enforceability of provisions that limit the obligation of a Guarantor based on the potential unenforceability, invalidity or voidability of a Guarantee under any applicable law, including, without limitation, any state or federal fraudulent transfer or fraudulent conveyance laws;

(4)we have relied (a) as to matters of Alberta, British Columbia and Ontario law upon the opinion of Bennett Jones LLP filed as Exhibit 5.2 to the Registration

4

Statement, and (b) as to matters of Dutch law upon the opinion of De Brauw Blackstone Westbroek New York B.V., filed as Exhibit 5.3 to the Registration Statement; and

(5)we express no opinion as to any matter other than as set forth herein, and no opinion may be inferred or implied herefrom.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the Prospectus forming part of the Registration Statement. By giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission issued thereunder.

Very truly yours,

/s/ Vinson & Elkins L.L.P.

Introduction

We have acted as special Alberta, Ontario and British Columbia counsel to Niska Gas Storage Partners LLC, a Delaware limited liability company (“Niska LLC”), in connection with the Registration Statement on Form S-3 (Reg.

Dear Sir/Madam,

Niska Gas Storage Partners LLC et al.

Registration on Form S-3 with the US Securities and Exchange Commission of

Common Units Representing Limited Liability Company Interests, Debt Securities, Guarantees, Units

1Introduction

I act as Dutch legal adviser (advocaat) to the Cooperative in connection with the registration with the US Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended, of units representing limited liability company interests in Niska Gas Storage Partners LLC and of Debt Securities of Niska Gas Storage Partners LLC, Niska Gas Storage US, LLC and Niska Gas Storage US Finance Corp, and of Niska Gas Storage Canada ULC and Niska Gas Storage Canada Finance Corp or any combination thereof, which Debt Securities may be guaranteed by certain Subsidiary Guarantors, including the Cooperative.

Certain terms used in this opinion are defined in the Annex (Definitions).

2Dutch Law

This opinion is limited to Dutch law in effect on the date of this opinion. It (including all terms used in it) is to be construed in accordance with Dutch law.

Attorneys at law, tax lawyers, candidate civil law notaries. Admitted in The Netherlands. Not admitted in New York.

De Brauw Blackstone Westbroek New York is De Brauw Blackstone Westbroek New York B.V., P.C., having its corporate seat in The Hague, the Netherlands, registered with the Trade Register in Amsterdam under no 27172369.

3Scope of Inquiry

For the purpose of this opinion, I have examined the following documents:

3.1A copy obtained on November 7, 2014 through www.sec.gov of the form of:

(a)

(i)the Senior Indenture;

(ii)the Subordinated Indenture;

(iii)the Notation of Guarantee be signed by the Cooperative and being a part of the Senior Indenture or the Subordinated Indenture, as the case may be; and

(b)a draft, dated November 7, 2014, of the Registration Statement.

3.2A copy of:

(a)the deed of incorporation of the Cooperative and its articles of association, as provided to me by the Chamber of Commerce; and

(b)the Trade Register Extract.

3.3A copy of each Corporate Resolution.

In addition, I have obtained the following confirmations given on the date of this opinion:

3.4Confirmation by telephone from the Chamber of Commerce that the Trade Register Extract is up to date.

3.5

(a)Confirmation by telephone from the court registry of the District Court of the place where the Cooperative has its seat, derived from that Court’s Insolvency Register; and

(b)confirmation through www.rechtspraak.nl, derived from the segment for EU registrations of the Central Insolvency Register;

in each case that the Cooperative is not registered as being subject to Insolvency Proceedings.

I have not examined any document, and do not express an opinion on, or on

2

any reference to, any document other than the documents referred to in this paragraph 3. My examination has been limited to the text of the documents and I have not investigated the meaning and effect of any document governed by a law other than Dutch law under that other law.

4Assumptions

For the purpose of this opinion, I have made the following assumptions:

4.1

(a)Each copy document conforms to the original and each original is genuine and complete.

(b)Each signature is the genuine signature of the individual concerned.

(c)Each confirmation referred to in this opinion is true.

4.2

(a)At the time when the Members Resolution was signed, the members which signed the Members Resolution were the only members of the Cooperative.

(b)Each Corporate Resolution remains in full force and effect without modification.

4.3The Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee) are within the capacity and powers of, and will have been validly authorised and entered into by, each party other than the Cooperative.

4.4Under New York Law by which the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee) are expressed to be governed:

(c)provided that the Senior Indenture and the Subordinated Indenture have been validly signed by all the respective parties to it, the Senior Indenture (including the relevant Guarantee) and Subordinated Indenture (including the relevant Guarantee), as the case may be are valid, binding on and enforceable against each party; and

(d)the choice of New York Law as the governing law of the Senior Indenture and the Subordinated Indenture applies to the submission to the jurisdiction of the New York Courts pursuant to the Jurisdiction

3

Clause in the Senior Indenture and the Subordinated Indenture, as the case may be.

5Opinion

Based on the documents and confirmations referred to and the assumptions made in paragraphs 3 and 4 and subject to the qualifications in paragraph 6 and to any matters not disclosed to me, I am of the following opinion:

5.1The Cooperative has been incorporated and exists as a cooperative (coöperatie).

5.2

(a)The Cooperative has the power to enter into and perform the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee).

(b)The Cooperative has taken all necessary action to authorise its entry into and performance of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee).

(c)When signed on behalf of the Cooperative by each director A acting jointly with director B, the Senior Indenture and the Notation of Guarantee referred to therein and the Subordinated Indenture and the Notation of Guarantee referred to therein, will have been validly signed by the Cooperative.

5.3

(a)The Cooperative does not require any licence, dispensation, recognition or other governmental consent for its entry into and performance of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee).

(b)There are no registration, filing or similar governmental formalities required to ensure the validity, binding effect on and enforceability against the Cooperative of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee).

5.4The entry into and performance of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee)

4

by the Cooperative do not violate Dutch law or the articles of association of the Cooperative.

5.5The choice of New York Law as the governing law of the Senior Indenture (including the relevant Guarantee) and of the Subordinated Indenture (including the relevant Guarantee) is recognised and accordingly that law governs the validity, binding effect on and enforceability against the Cooperative of the Senior Indenture (including the relevant Guarantee) and the Supplemental Indenture (including the relevant Guarantee), as the case may be.

5.6

(a)In proceedings in a New York Court, New York Law determines the validity, binding effect on and enforceability against the Cooperative of the Jurisdiction Clause.

(b)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.

6Qualifications

This opinion is subject to the following qualifications:

6.1This opinion is subject to any limitations arising from bankruptcy, suspension of payments, emergency measures, (other) Insolvency Proceedings or other laws relating to or affecting the rights of creditors.

6.2The recognition of New York Law as the governing law of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee):

(a)will not prejudice the provisions of the law of the European Community (where appropriate as implemented in the Netherlands) which cannot be derogated from by agreement if all elements relevant to the situation at the time when the Senior Indenture or the Subordinated Indenture was entered into (other than the choice of New York Law as the governing law of the Senior Indenture or the Subordinated Indenture) are located in one or more Member States of the European Union;

5

(b)

(i)will not restrict the application of the overriding provisions of Dutch law; and

(ii)will not prevent effect being given to the overriding provisions of the law of a jurisdiction with which the situation has a close connection;

(and for this purpose “overriding provisions” are provisions the respect for which is regarded as crucial by a jurisdiction for safeguarding its public interests to such an extent that they are applicable to any situation falling within their scope, irrespective of the law otherwise applicable to an agreement);

(c)will not prevent the application of New York Law being refused if it is manifestly incompatible with Dutch public policy (ordre public); and

(d)will not prevent regard having to be had to the law of the jurisdiction in which performance takes place in relation to the manner of performance and the steps to be taken in the event of defective performance.

6.3The enforcement in the Netherlands of the Senior Indenture (including the relevant Guarantee) or the Subordinated Indenture (including the relevant Guarantee) and of foreign judgments is subject to Dutch rules of civil procedure (including rules of evidence).

6.4The enforceability of the Senior Indenture (including the relevant Guarantee) and the Subordinated Indenture (including the relevant Guarantee) may be limited under the 1977 Sanction Act (Sanctiewet 1977) or otherwise by international sanctions.

6.5To the extent that pursuant to the Senior Indenture or the Subordinated Indenture the Cooperative is required or forbidden to take, or restricted in taking, any action that falls within the powers of its meeting of members, it may not be binding on and enforceable against it.

6.6To the extent that the Senior Indenture (including the relevant Guarantee) or the Subordinated Indenture (including the relevant Guarantee) constitutes general conditions within the meaning of Section 6:231 CC, a beneficiary of the Guarantee may nullify (vernietigen) a provision therein if (i) the beneficiary has not been given a reasonable opportunity to examine the Supplemented Indenture, or (ii) the provision, having regard to all relevant circumstances, is

6

unreasonably onerous to the holder. A provision in general conditions as referred to in Section 6:236 CC is deemed to be unreasonably onerous, irrespective of the circumstances, if the beneficiary of the Guarantee is a natural person not acting in the conduct of a profession or trade.

6.7To the extent that Dutch law applies, a legal act (rechtshandeling) performed by a person (including (without limitation) an agreement pursuant to which it guarantees the performance of another person’s obligations and any other legal act having a similar effect) may be nullified by any of its creditors, if (a) it performed the act without an obligation to do so (onverplicht), (b) the creditor concerned was prejudiced as a consequence of the act, and (c) at the time the act was performed both it and (unless the act was for no consideration (om niet)) the party with or towards which it acted, knew or should have known that one or more of its creditors (existing or future) would be prejudiced.

6.8If a legal act (rechtshandeling) performed by a Dutch legal entity (including (without limitation) an agreement pursuant to which it guarantees the performance of the obligations of another person and any other legal act having a similar effect) is not in the entity’s interest, the act may exceed the entity’s power.

6.9If a legal act (rechtshandeling) performed by a Dutch legal entity (including (without limitation) an agreement pursuant to which it guarantees the performance of another person’s obligations and any other legal act having a similar effect) is not in the entity’s interest, the act may (i) exceed the entity’s corporate or other power, (ii) violate its articles of association, and (iii) be nullified by it if the other party or parties to the act knew or should have known that the act is not in the entity’s interest.

6.10

(a)An extract from the Trade Register does not provide conclusive evidence that the facts set out in it are correct. However, under the 2007 Trade Register Act (Handelsregisterwet 2007), subject to limited exceptions, a legal entity or partnership cannot invoke the incorrectness or incompleteness of its Trade Register registration against third parties who were unaware of the incorrectness or incompleteness.

(b)A confirmation derived from an Insolvency Register does not provide conclusive evidence that an entity is not subject to Insolvency Proceedings.

7

6.11I do not express any opinion on any taxation matters.

7Reliance

7.1This opinion is an exhibit to the Registration Statement and may be relied upon for the purpose of the Registration. It may not be supplied, and its contents or existence may not be disclosed, to any person other than as an Exhibit to (and therefore together with) the Registration Statement and may not be relied upon for any purpose other than the Registration.

7.2Each person relying on this opinion agrees, in so relying, that only De Brauw shall have any liability in connection with this opinion, that the agreement in this paragraph 7.2 and all liability and other matters relating to this opinion shall be governed exclusively by Dutch law and that the Dutch courts shall have exclusive jurisdiction to settle any dispute relating to this opinion.

7.3The Cooperative may:

(a)file (or permit the registrants under the Registration Statement to file) this opinion as an exhibit to the Registration Statement; and

(b)refer (or permit the registrants under the Registration Statement to refer) to De Brauw under the heading “Legal Matters” in the prospectus included in the Registration Statement.

The previous sentence is no admittance from me (or De Brauw) that I am (or De Brauw is) in the category of persons whose consent for the filing and reference in that paragraph is required under Section 7 of the Securities Act or any rules or regulations of the SEC promulgated under it.
