7. The several obligations of the Underwriters hereunder shall be subject, in the discretion of the Representatives, to the condition that all representations and warranties and other statements of the Company herein are, at and as of the date hereof and the Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

8. (a) The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees, affiliates and agents, 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 or liabilities, joint or several, to which any of them may become subject, under the Securities Act, any BC Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) an untrue statement or alleged untrue statement of a material fact contained in the Base Prospectuses, the Preliminary Prospectuses, the Disclosure Package, any issuer free writing prospectus or road show (each as defined in Rule 433(h) under the Securities Act) or the Prospectuses or any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse such Underwriter or such director, officer, employee, affiliate, agent or controlling person for any legal or other expenses reasonably incurred by such Underwriter or such director, officer, employee, affiliate, agent or controlling person in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of

or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement or any amendment thereof, the Base Prospectuses, the Preliminary Prospectuses, the Disclosure Package, any issuer free writing prospectus or road show, each as defined in Rule 433(h) under the Securities Act, or the Prospectuses or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers and each 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 such Underwriter, its directors, officers, employees, affiliates, agents and controlling persons, but only with reference to information furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement or any amendment thereof, the Base Prospectuses, the Preliminary Prospectuses, the Disclosure Package, any issuer free writing prospectus or road show (each as defined in Rule 433(h) under the Securities Act) or the Prospectuses or any amendment or supplement thereto. The Company hereby acknowledges that the only information that the Underwriters have furnished to the Company through the Representatives expressly for use in the Registration Statement or any amendment thereof, the Base Prospectuses, the Preliminary Prospectuses, the Disclosure Package, any issuer free writing prospectus or road show (each as defined in Rule 433(h) under the Securities Act) or the Prospectuses or any amendment or supplement thereto, are the statements set forth in the first and second sentences of the third paragraph, the fifth paragraph and the sixth paragraph under the caption “Underwriting” in the Preliminary Prospectus.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection or to the extent it is not materially prejudiced as a proximate result of such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) 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 from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectuses. The relative fault 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 on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) 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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), 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 were offered 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(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have.

9. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, the Representatives may in their discretion arrange for the Underwriters or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such

Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectuses, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectuses which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, its directors, officers, employees, affiliates or agents or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities and any termination of this Agreement.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives jointly or singly on behalf of the Underwriters.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the Representatives in care of BNP Paribas Securities Corp., 787 Seventh Avenue, 7th Floor, New York, NY 10019-6016, Attention: Debt Capital Markets Group, Fax: (212) 841-2140, J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Investment Grade Syndicate Desk, Fax: (212) 834-6081 and RBC Capital Markets, LLC, Three World Financial Center, 200 Vesey Street, 9th Floor, New York, New York 10281, Attention: Debt Capital Markets, Email: usdebtcapitalmarkets@rbccm.com; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Chief Financial Officer; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. The Company hereby acknowledges that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters and any affiliate through which it may be acting, on the other hand, and the Company 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 financial advisor, agent or fiduciary of the Company or any of its affiliates, shareholders, creditors or employees or any other party, (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company 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 on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby 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 several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Underwriters, or any of them, with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 8 and 10 hereof, the directors, officers, employees, affiliates, agents and controlling persons referred to therein, and, in each case, their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. The Company irrevocably (i) agrees that any legal suit, action or proceeding against the Company brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any New York Court, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company irrevocably waives any immunity to jurisdiction to which it may otherwise be entitled or become entitled (including sovereign immunity, immunity to pre-judgment attachment, post-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement or the transactions contemplated hereby which is instituted in any New York Court or in any competent court in Canada. The Company has appointed CT Corporation System located at 111 Eighth Avenue, New York, New York 10011, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any New York Court by any Underwriter or by any person who controls any Underwriter, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. The Company represents and warrants that the Authorized Agent has agreed to act as such agent for service of process and agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to the Company shall be deemed, in every respect, effective service of process upon the Company.

16. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than United States dollars, the Company will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars.

17. Time shall be of the essence of this Agreement. As used herein, and except as otherwise provided, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the Company and the Underwriters shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the Company and the Underwriters that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

19. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile, email or other electronic transmission (i.e., “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement.

21. This Agreement may be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may be given, provided that the same are in writing and signed by all of the signatories hereto.

22. The Company is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriters imposing any limitation of any kind.

If the foregoing is in accordance with your understanding, please sign and return to us five counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this Agreement and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company. It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement Among Underwriters, the form of which shall be submitted to the Company for examination upon request, but without warranty on your part as to the authority of the signers thereof.


Very truly yours,

We have acted as special United States counsel to Methanex Corporation, a Canadian corporation (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated as of November 13, 2014, among the Company and the several underwriters named in Schedule I thereto (the “Underwriters”), for whom you are acting as representatives, relating to the purchase today by the Underwriters of US$300,000,000 aggregate principal amount of the Company’s 4.250% Senior Notes due 2024 (the “2024 Notes”) and US$300,000,000 aggregate principal amount of the Company’s 5.650% Senior Notes due 2044 (the “2044 Notes” and, together with the 2024 Notes, the “Notes”). This opinion is being furnished at the request of the Company as contemplated by section 7(c) of the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

the Company dated October 31, 2014 (the “Form F-X”) and the Form T-1 of the Trustee dated October 30, 2014 (the “Form T-1”) were filed with the Commission prior to the effectiveness of the Registration Statement. In this opinion, the Registration Statement at the time it became effective under the Act, including the documents incorporated by reference therein, is referred to as the “Registration Statement”; the base prospectus, dated November 7, 2014, contained in the Registration Statement at the time it became effective (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement dated November 13, 2014, including the documents incorporated by reference therein immediately prior to the Applicable Time, is referred to as the “Preliminary Prospectus”; the Preliminary Prospectus, taken together with the information set forth in the pricing term sheet, dated November 13, 2014 and filed with the Commission pursuant to Rule 433 of the Act, is referred to as the “Disclosure Package”; and the Base Prospectus, as supplemented by the final prospectus supplement dated November 13, 2014, including the documents incorporated by reference therein, is referred to as the “Prospectus”. Both the Preliminary Prospectus and the Prospectus have been filed pursuant to General Instruction II.L of Form F-10 in the manner and within the time period required by said General Instruction II.L. The Company has also filed a short form base shelf prospectus, dated October 30, 2014, which short form base shelf prospectus was amended on November 7, 2014 (as amended, the “Canadian Base Prospectus”), a preliminary prospectus supplement, dated November 13, 2014, and a final prospectus supplement (together with the Canadian Base Prospectus and the documents incorporated by reference therein, the “Canadian Final Prospectus”), dated November 13, 2014, in each case with the British Columbia Securities Commission, as principal regulator.

The Commission’s website indicates that no stop order suspending the effectiveness of the Registration Statement has been issued.

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents:

In addition, we have examined such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions and beliefs expressed below. We have also relied upon oral and written statements of officers and representatives of the Company, the factual matters contained in the representations and warranties made in the Underwriting Agreement and upon certificates of public officials and officers of the Company. The documents incorporated by reference into the Registration Statement and the Prospectus were prepared by the Company without our participation.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the enforceability of documents against each party to the documents other than the Company, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

We have also assumed, without independent investigation that (i) the Company is validly existing and in good standing under the laws of its jurisdiction of organization, (ii) the Company has all necessary corporate power to execute, deliver and perform its obligations under the Underwriting Agreement, the Indenture, the Supplemental Indenture and the Notes (collectively, the “Operative Documents”), (iii) the execution, delivery and performance of the Operative Documents have been duly authorized by all necessary corporate action and do not violate the Certificate of Continuance, By-laws or other organizational documents of the Company or the laws of its jurisdiction of organization, (iv) the due execution and delivery of the Operative Documents under the laws of its jurisdiction of organization, and (v) that each of the parties (other than the Company) to the Operative Documents has complied with all of its obligations and covenants arising under the Operative Documents. We have also assumed that the Indenture and the Supplemental Indenture each constitute the legal, valid and binding obligation of the Trustee and the due authentication of the Notes by the Trustee in the manner described in the certificate of the Trustee delivered to you today.

Based upon the foregoing, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

1. The Registration Statement and the 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 and the Form T-1, as to which we express no opinion; the Form F-X, as of its date, appears on its face to be appropriately responsive in all material respects to the requirements of the Act. We have assumed, for purposes of this paragraph, the compliance of the Canadian Base Prospectus and the Canadian Final Prospectus with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission. We understand that such matters are covered in the opinion of McCarthy Tétrault LLP furnished to you today.

2. No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made is required by the Company under those laws, rules and regulations of the United States of America and the State of New York (“Applicable Law”), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement, for the issuance and sale of the Notes by the Company, the execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Supplemental Indenture and the performance by the Company of its obligations

thereunder. For purposes of this letter, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of the State of New York or the United States of America. For purposes of this letter, the term “Applicable Law” does not include securities laws, anti-fraud laws, or any law, rule or regulation that is applicable to the Company, the Operative Documents or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any party to the Underwriting Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate.

3. The Indenture (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Company. The Indenture constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that the enforceability of the Indenture may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and possible judicial action giving effect to governmental actions relating to persons or transactions or foreign laws affecting creditors’ rights and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); and the Indenture conforms in all material respects to its description contained in the Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities.” The Indenture has been duly qualified under the Trust Indenture Act.

4. The Supplemental Indenture (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Company. The Supplemental Indenture constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that the enforceability of the Supplemental Indenture may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and possible judicial action giving effect to governmental actions relating to persons or transactions or foreign laws affecting creditors’ rights and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); and the Supplemental Indenture conforms in all material respects to its description contained in the Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities.”

5. The Notes (to the extent execution and delivery are governed by the laws of New York) have been duly executed and delivered by the Company. The Notes, when duly issued and delivered by the Company against payment as provided in the Underwriting Agreement, will constitute the legal, valid and binding obligations of the Company entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, except that the enforceability of the Notes may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and possible judicial action giving effect to governmental actions relating to persons or transactions or foreign laws affecting creditors’ rights and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); and the Notes, when issued and delivered, will conform in all material respects to the description contained in the Disclosure Package and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities.”

6. The Underwriting Agreement (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Company.

7. The Company is not and, after giving effect to the offering and sale of the Notes and the application of their proceeds as described in the Disclosure Package and the Prospectus under the heading “Use of Proceeds,” will not be required to be registered as an investment company under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

8. The statements in the Disclosure Package and the Prospectus under the heading “Certain Income Tax Considerations — Certain United States Federal Income Tax Considerations,” to the extent that they constitute summaries of United States federal law or regulation or legal conclusions, have been reviewed by us and fairly summarize the matters described under that heading in all material respects.

9. Under the laws of the State of New York relating to submission to jurisdiction, the Company has, pursuant to Section 15 of the Underwriting Agreement and Section 13.10 of the Indenture, validly and irrevocably submitted to the personal jurisdiction of any state or federal court located in the State of New York, in any action arising out of or relating to the Underwriting Agreement or the Indenture or the transactions contemplated thereby, has validly and irrevocably waived any objection to the venue of a proceeding in any such court, and has validly and irrevocably appointed the Authorized Agent as its authorized agent for the purpose described in Section 15 of the Underwriting Agreement and Section 13.10 of the Indenture; and service of process effected on such agent in the manner set forth in Section 15 of the Underwriting Agreement and Section 13.10 of the Indenture will be effective to confer valid personal jurisdiction over the Company. This opinion (9) is subject to the qualification that we express no opinion as to the enforceability of forum selection clauses in the federal courts.

The opinions expressed above are limited to the laws of the State of New York and the federal laws of the United States of America. Our opinions are rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect. We express no opinion with respect to the enforceability of any indemnity against any loss in converting into a specified currency the proceeds or amount of a court judgment in another currency.

This letter is furnished by us solely for the benefit of the Underwriters in connection with the transactions referred to in the Underwriting Agreement and may not be circulated to, or relied upon by, any other person without our prior written consent.

We have acted as special United States counsel to Methanex Corporation, a Canadian corporation (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated as of November 13, 2014, among the Company and the several underwriters named in Schedule I thereto (the “Underwriters”), for whom you are acting as representatives, relating to the purchase today by the Underwriters of US$300,000,000 in aggregate principal amount of the Company’s 4.250% Senior Notes due 2024 (the “2024 Notes”) and US$300,000,000 in aggregate principal amount of the Company’s 5.650% Senior Notes due 2044 (the “2044 Notes” and, together with the 2024 Notes, the “Notes”). This letter is being furnished at the request of the Company in connection with the delivery of our opinion to you of even date herewith (the “Opinion”) under the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form F-10 (File No. 333-199756) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on October 31, 2014, was amended on November 7, 2014 and, based on our review of the Commission’s EDGAR database on November 12, 2014, was declared effective by the Commission at 9:00 a.m. on November 10, 2014. In this letter, the Registration Statement at the time it became effective under the Act, including the documents incorporated by reference therein, is referred to as the “Registration Statement”; the base prospectus, dated November 7, 2014, contained in the Registration Statement at the time it became effective (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement dated November 13, 2014, including the documents incorporated by reference therein immediately prior to the Applicable Time, is referred to as the “Preliminary Prospectus”; the Preliminary Prospectus, taken together with the information set forth in the pricing term sheet, dated November 13, 2014 and filed with the Commission pursuant to Rule 433 of the Act, is referred to as the “Disclosure Package”; and the Base Prospectus, as supplemented by the final prospectus supplement dated November 13, 2014, including the documents incorporated by reference therein, is referred to as the “Prospectus”. Both the Preliminary Prospectus and the Prospectus have been filed pursuant to General Instruction II.L of Form F-10 in the manner and within the time period required by said General Instruction II.L.

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Registration Statement, the Preliminary Prospectus and the Prospectus are of a wholly

or partially non-legal character or relate to legal matters outside the scope of this letter. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the General Disclosure Package, the Preliminary Prospectus, the Prospectus or the documents incorporated by reference therein (other than as explicitly stated in paragraphs 3, 4, 5 and 8 of the Opinion).

In the course of acting as special counsel to the Company in connection with the offering of the Notes, we have participated in the preparation of the Registration Statement, the Disclosure Package and the Prospectus and in conferences and telephone conversations with your representatives, including your United States counsel, officers and other representatives of the Company, the Company’s Canadian counsel and the independent registered public accountants for the Company, during which conferences and conversations the contents of the Registration Statement, the Preliminary Prospectus, the Prospectus and related matters were discussed. Based upon such participation (and relying as to factual matters on officers, employees and other representatives of the Company and its subsidiaries), our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we hereby advise you that our work in connection with this matter did not disclose any information that caused us to believe that (i) as of the Applicable Time, the Registration Statement (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference and the Form T-1, as to which we express no such belief) included 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; (ii) as of the Applicable Time, the Disclosure Package (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we express no such belief) 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 (iii) at the time the Prospectus was issued or at the Closing Date, the Prospectus (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we express no such belief) 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.

This letter is furnished by us solely for your benefit in connection with the transactions referred to in the Underwriting Agreement and may not be circulated to, or relied upon by, any other person without our prior written consent.

We have acted as Canadian counsel to Methanex Corporation (the “Corporation”) in connection with the issue by the Corporation and the purchase by BNP Paribas Securities Corp., J.P. Morgan Securities LLC, RBC Capital Markets, LLC, BMO Capital Markets Corp., HSBC Securities (USA) Inc., nabSecurities, LLC and RBS Securities Inc. (together, the “Underwriters”) of US$300,000,000 aggregate principal amount of 4.250% Senior Notes due 2024 (the “2024 Notes”) and US$300,000,000 aggregate principal amount of 5.650% Senior Notes due 2044 (the “2044 Notes” and, together with the 2024 Notes, the “Notes”) pursuant to an underwriting agreement (the “Underwriting Agreement”) dated as of November 13, 2014 among the Underwriters and the Corporation. The Notes are being created and issued pursuant to a trust indenture (the “Initial Indenture”) made as of July 20, 1995 between the Corporation and The Bank of New York Mellon (formerly United States Trust Company of New York), as trustee (the “Trustee”), as supplemented by a supplemental indenture dated as of June 18, 2002 (the “First Supplemental Indenture”), a supplemental indenture dated as of June 19, 2002 (the “Second Supplemental Indenture”), a supplemental indenture dated as of December 9, 2003 (the “Third Supplemental Indenture”), a supplemental indenture dated as of August 3, 2005 (the “Fourth Supplemental Indenture”), a supplemental indenture dated as of February 28, 2012 (the “Fifth Supplemental Indenture”) and a supplemental indenture dated as of November 18, 2014 (the “Sixth Supplemental Indenture”) between the Corporation and the Trustee (the Initial Indenture, the First Supplemental Indenture, the Second Supplemental Indenture, the Third Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental Indenture and the Sixth Supplemental Indenture being referred to collectively herein as the “Indenture”). Capitalized terms used and not otherwise defined herein have the meanings ascribed to such terms in the Underwriting Agreement.

In connection with the distribution of the Notes by the Underwriters, the Corporation has prepared, pursuant to National Instrument 44-101 – Short Form Prospectus Distributions and National

Instrument 44-102 – Shelf Distributions, and filed with the British Columbia Securities Commission (the “BCSC”) (i) a preliminary short form base shelf prospectus, dated October 31, 2014 (the “Canadian Preliminary Base Prospectus”) (including the documents incorporated or deemed to be incorporated by reference therein), (ii) a final short form base shelf prospectus, dated November 7, 2014 (the “Canadian Base Prospectus”) (including the documents incorporated or deemed to be incorporated by reference therein), (iii) a preliminary prospectus supplement, dated November 13, 2014 relating to the offering of the Notes (the “Canadian Preliminary Prospectus”) (including the documents incorporated or deemed to be incorporated by reference therein), and (iv) a final prospectus supplement, dated November 13, 2014, relating to the offering of the Notes (the “Canadian Final Prospectus”) (including the documents incorporated or deemed to be incorporated by reference therein) (the Canadian Final Prospectus, together with the Canadian Base Prospectus is referred to herein as the “Canadian Prospectus”).

The Corporation has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form F-10 (File No. 333-199756) (as amended, together with the documents incorporated by reference therein, the “Registration Statement”) under the Securities Act of 1933, as amended (the “1933 Act”). The Registration Statement was filed on October 31, 2014, was amended on November 10, 2011 and was declared effective by the Commission at 9:00 a.m. on November 10, 2014.

The base prospectus, dated November 10, 2014 contained in the Registration Statement at the time it became effective (the “U.S. Base Prospectus”), as supplemented by the preliminary prospectus supplement dated November 13, 2014, together with the documents incorporated by reference therein, are referred to, collectively, as the “U.S. Preliminary Prospectus”. The U.S. Base Prospectus, as supplemented by the final prospectus supplement dated November 13, 2014, together with the documents incorporated by reference therein and the final term sheet substantially in the form set forth in Annex I of the Underwriting Agreement, are referred to, collectively, as the “U.S. Prospectus”. The Canadian Prospectus and the U.S. Prospectus are referred to herein as the “Prospectuses”. Both the U.S. Preliminary Prospectus and the U.S. Prospectus have been filed pursuant to General Instruction II.L of Form F 10.

We have participated in the preparation of or have examined the following documents and agreements:

We have also examined such statutes, public records, corporate records and documents and certificates of public officials and officers of the Corporation, have considered such matters of law and have made such enquiries of officers of the Corporation and other persons as we have considered appropriate or necessary as a basis for the opinions expressed herein. In such examinations, we have assumed (i) the genuineness of all signatures on the documents examined by us and, except with respect to the Corporation, the authority of all persons signing documents examined by us, (ii) the authenticity of all documents examined by us which were submitted to us as originals, (iii) the conformity to authentic original documents of all documents examined by us which were submitted to us as certified, conformed, facsimile or photostatic copies of original documents and (iv) the identity and capacity of all individuals acting or purporting to act as public officials.

The opinions hereinafter expressed are limited to the laws of the Province of British Columbia and the federal laws of Canada applicable therein on the date hereof. Accordingly, our opinions in paragraphs 5 and 6 below are limited to the due authorization, execution and delivery of the Underwriting Agreement, the Indenture and the Notes and the due issuance of the Notes under the laws of the Province of British Columbia and the federal laws of Canada applicable therein and we express no opinion with respect to the requirements of the Underwriting Agreement or the Indenture, which are matters of New York law. We understand that you are being provided with and are relying upon an opinion dated the date hereof of Paul, Weiss, Rifkind, Wharton & Garrison LLP with respect to the laws of the United States of America and the State of New York related to the creation, offering and sale of the Notes and certain other matters including, without limitation, satisfaction of the requirements of the Act and the Trust Indenture Act. Paul, Weiss, Rifkind, Wharton & Garrison LLP may rely on this opinion for the purposes of such opinion, as if this opinion were addressed to them.

The qualification of any opinion or statement herein with respect to the existence or absence of facts by “to our knowledge” means actual knowledge of the lawyers of our firm involved in the preparation of the Offering Materials without any independent investigation or inquiry.

In expressing the opinions set forth below we have assumed, without independent investigation, that the Indenture and the Underwriting Agreement have been duly authorized, executed and delivered by and constitute valid and legally binding obligations of the Trustee and the Underwriters, respectively, that the Notes conform to the specimen thereof examined by us and that the Trustee’s certificates of authentication of the Notes have been manually signed by one of the Trustee’s authorized officers.

Based and relying upon and subject to the foregoing, we are of the opinion that at the date hereof:

1. The Corporation has been duly continued and is validly existing as a corporation under the federal laws of Canada, with corporate power and authority to own its properties and conduct its business as described in the Prospectuses, and the Corporation has all requisite corporate power and authority to execute, deliver and perform its obligations under the Underwriting Agreement, the Indenture and the Notes.

2. The Corporation has an authorized capitalization as set forth in the Prospectuses and all of the issued and outstanding shares in the capital of the Corporation have duly authorized and validly issued and are fully paid and non-assessable.

3. The Corporation has been extra-provincially registered or otherwise duly qualified as an extra-provincial or as a foreign corporation for the transaction of business under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, or is subject to no material liability or disability by reason of the failure to be so qualified in any such jurisdiction.

4. To our knowledge, based solely upon documents provided to us by the Corporation and conferences with officers and other representatives of the Corporation in connection with the offering of the Notes, and other than as set forth in the Prospectuses, there are no legal or governmental proceedings pending to which the Corporation or any of its subsidiaries is a party or of which any property of the Corporation or any of its subsidiaries is the subject which are of a character required by the Securities Act (British Columbia) and the rules, regulations and published policy statements applicable in the Province of British Columbia (“British Columbia Securities Laws”) to be described or referred to in the Prospectuses and no such proceedings are threatened or contemplated by any Governmental Agency or threatened by others.

5. The Underwriting Agreement has been duly authorized and, to the extent that execution and delivery are governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein, executed and delivered by the Corporation.

6. The Indenture and the Notes have been duly authorized and, to the extent that execution, issuance and delivery are matters governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein, the Indenture has been duly executed and delivered by the Corporation and the Notes have been duly executed, issued and delivered by the Corporation, and the Indenture and the Notes conform in all material respects to the descriptions thereof in the Prospectuses.

7. The form of global certificate representing the Notes, as included in the Indenture, has been duly approved and adopted by the Corporation and complies in all material respects with all applicable statutory requirements of the Province of British Columbia and of Canada applicable therein and with any applicable requirements of the constating documents of the Corporation.

8. The Indenture and the issuance of the Notes thereunder comply, to the extent applicable, with the provisions of the Canada Business Corporations Act. No registration, filing or recording of the Indenture under British Columbia Securities Laws is necessary in order to preserve or protect the validity or enforceability of the Indenture or the Notes issued thereunder.

9. The issue and sale of the Notes and the compliance by the Corporation with all of the provisions of the Notes, the Indenture and the Underwriting Agreement and the consummation by the Corporation of the transactions therein contemplated will not (A) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any of the agreements or instruments set forth in Schedule “A” to the Officer’s Certificate, (B) result in any violation of the provisions of the Articles of Continuance or the By-laws, as amended of the Corporation, or (C) contravene any federal, provincial or local law, rule or regulation of the Province of British Columbia or Canada applicable to the transactions contemplated by the issue and sale of the Notes or the provisions of the Indenture or the Underwriting Agreement or, to the best of our knowledge, any order applicable to the Corporation of any court or of any other governmental body or instrumentality having jurisdiction over it or any of its property that would have a Material Adverse Effect (it being understood that for the purpose of this clause (C), we are not passing upon compliance with respect to antifraud or similar provisions of any law, rule or regulation).

10. No Governmental Authorization of or with any Governmental Agency in Canada is required for the issue and sale of the Notes or the consummation by the Corporation of the transactions contemplated by the Underwriting Agreement or the Indenture, except such as have been obtained.

11. To our knowledge, the Corporation is not in violation of its constating documents or in default in the performance or observance of any material obligation, covenant or condition contained in any of the agreements or instruments set forth in Schedule “A” to the Officer’s Certificate.

12. To our knowledge, all descriptions in the Prospectuses of contracts, agreements, arrangements and other documents to which the Corporation or its subsidiaries are a party are correct in all material respects.

13. The information in the Registration Statement under “Part II – Indemnification of Directors and Officers” and the statements set forth in the Prospectuses under the captions “Risk Factors — It may be difficult for you…”, “Description of the Notes — Enforceability of Judgments” and “Tax Considerations — Certain Canadian Federal Income Tax Considerations”, insofar as they purport to describe the provisions of the laws of the Province of British Columbia or the federal laws of Canada applicable therein, and under the caption “Underwriting”, have been reviewed by us and, to the extent that such statements constitute matters of law or legal conclusions, such statements fairly present the information disclosed therein and, insofar as such statements purport to describe the provisions of laws or documents referred to therein, such statements are correct in all material respects, in each case subject to the qualifications, limitations and assumptions set out under each such caption in the Registration Statement or the Prospectuses, as applicable.

14. Insofar as matters of the laws of the Province of British Columbia and the federal laws of Canada applicable therein are concerned, the Registration Statement and the filing of the Registration Statement with the Commission have been duly authorized by and on behalf of the Corporation, and the Registration Statement has been duly executed pursuant to such authorization by and on behalf of the Corporation.

15. A final receipt has been obtained in respect of the Canadian Base Prospectus from the BCSC and, subject to the filing of standard post-closing notices, all necessary documents have been filed, all necessary proceedings have been taken and all necessary authorizations, approvals, permits and consents have been obtained under British Columbia Securities Laws to permit the Notes to be offered, sold and delivered, as contemplated by the Underwriting Agreement and pursuant to the U.S./Canada Multi-Jurisdictional Disclosure System (“MJDS”), in the United States, and no other Governmental Authorization of or with any Governmental Agency in Canada or the Province of British Columbia is

required for such offering, sale or delivery of the Notes pursuant to the MJDS in the United States or the consummation by the Corporation of the transactions contemplated by the Underwriting Agreement, except such as have been obtained.

16. The Corporation is a “reporting issuer” under the securities legislation of the Province of British Columbia and is not on the list of defaulting issuers maintained under such legislation, and the Corporation meets the general requirements to use a short form prospectus under National Instrument 44-101 – Short Form Prospectus Distributions.

17. There are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments referred to in the Prospectuses that in accordance with the requirements of the BCSC are required to be made publicly available in connection with the offering of the Notes that have not been made publicly available as would be required, and there are no documents required to be filed with the BCSC in connection with the offering of the Notes that have not been filed as required.

18. No withholding tax imposed under the Income Tax Act (Canada) will be payable in respect of the payment of the Underwriters’ Commission by the Corporation to an Underwriter, provided that the Underwriter deals at arm’s length with the Corporation (as such term is understood for purposes of the Income Tax Act (Canada)); the services performed by the Underwriter for which the Underwriters’ Commission is payable are performed in the ordinary course of business carried on by the Underwriter that includes the performance of such services for a fee; the amount of each such payment is reasonable in the circumstances; and each such payment is made in respect of services rendered by the Underwriter wholly outside of Canada.

19. No goods and services tax imposed under the federal laws of Canada will be payable by the Corporation to, or collectable by, an Underwriter that is not a resident of Canada, in respect of the payment of the Underwriters’ Commission to such Underwriter, provided that each such payment is made in respect of services performed by the Underwriter wholly outside of Canada.

20. No stamp duty, documentary, value added or transfer taxes are payable by the Corporation under the federal laws of Canada or the laws of the Province of British Columbia in connection with the sale and delivery of the Notes by the Corporation pursuant to the Underwriting Agreement.

21. A court of competent jurisdiction in the Province of British Columbia (a “British Columbia Court”) would give effect to the choice of the law of the State of New York (“New York law”) as the proper law governing the Underwriting Agreement, the Indenture and the Notes, provided that such choice of law is: (A) bona fide (primarily in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction); (B) legal; and (C) not contrary to public policy as that term is applied by a British Columbia Court (“Public Policy”). In our opinion, no Public Policy would be offended by recognition of this choice of law, nor are we aware of any basis upon which such choice of law would not be bona fide and legal.

22. In an action on a final and conclusive judgment in personam of any federal or state court in the State of New York (a “New York Court”) that is not impeachable as void or voidable under New York law, a British Columbia Court would give effect to the appointment by the Corporation of CT Corporation System as its agent to receive service of process in the United States of America under the Underwriting Agreement and the Indenture and to the provisions therein whereby the Corporation submits to the non-exclusive jurisdiction of a New York Court except that a British Columbia Court may not consider itself bound by any provision of the Underwriting Agreement or the Indenture purporting to make that submission to jurisdiction exclusive.

23. If the Underwriting Agreement, the Indenture or the Notes are sought to be enforced in the Province of British Columbia in accordance with the laws applicable thereto as chosen by the parties, namely New York law, a British Columbia Court would, subject to the opinion expressed in paragraph 21 above, recognize the choice of New York law and, upon such law being specifically pleaded and appropriate evidence as to such law being adduced, apply such law to all issues that under the conflict rules of the Province of British Columbia, are to be determined in accordance with the proper or governing law of the contract, provided that: (A) none of the provisions of the Underwriting Agreement, the Indenture or the Notes, as the case may be, or of applicable New York law, are contrary to Public Policy; (B) that such New York law does not constitute, directly or indirectly, revenue, expropriatory, public or penal laws; (C) in matters of procedure, the laws of the Province of British Columbia will be applied; (D) a British Columbia Court will retain discretion to decline to hear such action if it is contrary to Public Policy for it to do so, or if it is not the appropriate forum to hear such an action, or if concurrent proceedings are being brought elsewhere; and (E) a British Columbia Court may not enforce an obligation enforceable under the laws of the Province of British Columbia where performance of the obligation would be illegal under the laws of the place of performance.

24. The laws of the Province of British Columbia and the federal laws of Canada applicable therein permit an action to be brought in a British Columbia Court on a final and conclusive judgment in personam of a New York Court that is subsisting and unsatisfied respecting the enforcement of the Underwriting Agreement, the Indenture or the Notes, that is not impeachable as void or voidable under New York law and that is for a sum certain if: (A) the New York Court that rendered such judgment had jurisdiction over the judgment debtor, as recognized by a British Columbia Court (and submission by the Corporation in the Underwriting Agreement and the Indenture to the jurisdiction of the New York Court will be deemed sufficient for such purpose); (B) proper service of process in respect of the proceeding in which such judgment was obtained was made in accordance with New York law; (C) such judgment was not obtained by fraud or in a manner contrary to natural justice and the enforcement thereof would not be inconsistent with Public Policy or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or contrary to any order made by the Competition Tribunal under the Competition Act (Canada); (D) the enforcement of such judgment in British Columbia does not constitute, directly or indirectly, the enforcement of any laws of the State of New York or of the United States of America which a British Columbia Court would characterize as revenue, expropriatory, public or penal laws; (E) in an action to enforce a default judgment, the judgment does not contain a manifest error on its face; (F) the action to enforce such judgment is commenced within the applicable limitation period after the date of such judgment; and (G) the judgment does not conflict with another final and conclusive judgment in the same cause of action, provided that a British Columbia Court may stay an action to enforce a foreign judgment if an appeal of a judgment is pending or the time for appeal has not expired, and provided, further, that under the Currency Act (Canada) a British Columbia Court may only give judgment in Canadian dollars.

25. No Governmental Authorization of or with any Governmental Agency is required to effect payments of principal, premium, if any, and interest on the Notes.

26. The Canadian Prospectus appears on its face to be responsive as to form in all material respects to the requirements of British Columbia Securities Laws as interpreted and applied by the BCSC.

This opinion is delivered solely for the benefit of the persons to whom it is addressed, except as otherwise indicated herein, and may not be quoted, filed with any governmental authority or other regulatory agency or otherwise circulated or utilized for any purposes without our prior written consent.

We have acted as Canadian counsel to Methanex Corporation (the “Corporation”) in connection with the underwriting agreement dated November 13, 2014 (the “Underwriting Agreement”) among the Corporation and the several underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), in connection with the public offering by the Corporation of US$300,000,000 aggregate principal amount of 4.250% Senior Notes due 2024 (the “2024 Notes”) and US$300,000,000 aggregate principal amount of 5.650% Senior Notes due 2044 (the “2044 Notes” and, together with the 2024 Notes, the “Notes”).

This letter is being furnished to you pursuant to Section 7(d) of the Underwriting Agreement. All defined terms not otherwise defined herein have the meanings attributed to them in the Underwriting Agreement.

As such counsel, we have participated, together with Paul, Weiss, Rifkind, Wharton & Garrison LLP, U.S. counsel for the Corporation, and Shearman & Sterling LLP, U.S. counsel for the Underwriters, in the preparation and have reviewed copies of the Canadian Base Prospectus, the Canadian Preliminary Prospectus, the Canadian Prospectus and the Canadian Offering Memorandum (collectively, the “Canadian Disclosure Package”).

In the course of the preparation by the Corporation of the Canadian Disclosure Package, we have participated in conferences with certain of the officers and representatives of, and the independent chartered accountants for, the Corporation, at which the contents of the Canadian Disclosure Package were discussed. Given the limitations inherent in the independent verification of factual matters and the character of determinations involved in the prospectus filing process in Canada, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Canadian Disclosure Package, and have made no independent check or verification thereof. Subject to the foregoing, and on the basis of information gained in the course of the performance of the services referred to above, including information obtained from officers and representatives of, and the independent chartered accountants for, the Issuer, no facts have come to our attention that cause us to believe that the Canadian Disclosure Package, as of its 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 not misleading. However, we express no view or belief with respect to financial statements, notes or schedules and other financial, accounting or statistical data included in, incorporated into or omitted from the Canadian Disclosure Package.

Our comments set out above as to the absence of material facts which have come to our attention which could be indicative of a misrepresentation in the Canadian Disclosure Package are based on our experience in practising securities law in the Province of British Columbia and on the meanings of the terms “material fact” and “misrepresentation” as stated below. Such comments are limited to the meanings of such terms under the laws of the Province of British Columbia and the federal laws of Canada applicable therein.

References in this letter to “material fact” are to the definition of such term in Section 1 of the Securities Act (British Columbia) (“BCSA”). Under the BCSA, a determination of whether a fact is a material fact is principally a factual, not a legal, matter, requiring a determination as to the effect information would have on market prices or values of the relevant securities.

References in this letter to “misrepresentation” are to the definition of such term in Section 1 of the BCSA. Under the BCSA, misrepresentation is defined as (a) an untrue statement of material fact, or (b) an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in the light of the circumstances in which it was made.

This letter is furnished to you at your request solely for your benefit in connection with your use of the Canadian Disclosure Package, and may not be relied upon in any manner or for any purpose by any other person and may not to be quoted, in whole or in part, without our prior written consent.
