15

7.Covenants of the Underwriters.  (a)  Each Underwriter represents and warrants to, and agrees with, the Company and each other Underwriter that it has not made, and will not make, any offer relating to the Securities that would constitute a "free writing prospectus" (as defined in Rule 405 under the Act), without the prior consent of the Company and the Representatives; provided,however, that prior to the preparation of the final term sheet substantially in the form set forth in Schedule IV hereto, the Underwriters are authorized to use a free writing prospectus that contains only information (i) describing the preliminary terms of the Securities or their offering or (ii) describing the final terms of the Securities which will not be inconsistent with the final term sheet substantially in the form set forth in Schedule IV hereto.

(b)Each Underwriter (i) represents that it has not offered or sold, directly or indirectly, and agrees that it will not, directly or indirectly, offer, sell or deliver, any of the Securities in or from Canada or to any resident of Canada without the consent of the Company and (ii) agrees that it will include a comparable provision to clause (i) above of this Section 7(b) in any sub-underwriting, banking group or selling group agreement or similar arrangement with respect to the Securities that may be entered into by such Underwriter.

8.Indemnity and Contribution.  (a) The Company agrees to indemnify and hold harmless each Underwriter, 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, each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act and each agent of any Underwriter from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the Basic Prospectuses, the Preliminary Prospectuses, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or the Prospectuses or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to

18

the Company in writing by such 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 who sign the Registration Statement 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, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement or any amendment thereof, the Basic Prospectuses, any preliminary prospectus, the Time of Sale Prospectus, the Prospectuses, any issuer free writing prospectus or any amendment or supplement thereto.

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

19

includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d)To the extent the indemnification provided for in Section 8(a) or Section 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters bear to the aggregate initial public offering price of the Securities as set forth in the Prospectus.  The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Securities they have purchased hereunder, and not joint.

(e)The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

20

(f)The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate or agent of any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9.Termination.  The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Time of Delivery (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NASDAQ Stock Market or the Toronto Stock Exchange, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States or Canada shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State, Canadian federal or Ontario provincial authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectuses.

10.Effectiveness; Defaulting Underwriters.  This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase the Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Underwriters' Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule II bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided,that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Underwriter.  If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase the Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company.  In any such case either the Representatives or the Company shall have the right to postpone the Closing Date,

"Reset Interest Determination Date" means the day falling two Business Days prior to the Reset Date.

"Reset Reference Bank Rate" means the percentage rate determined on the basis of the 5-Year Mid-Swap Rate Quotation provided by five leading swap dealers in the interbank market (selected by the Company) to the Company at approximately 11:00 a.m. (New York time) on the Reset Interest Determination Date. If at least three quotations are provided, the 5-Year Mid-Swap Rate will be the arithmetic mean of the quotations calculated by the Company, eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest).

Ranking and Subordination:	The Notes will be direct, unsecured obligations of the Company and will be subordinated in right of payment to all Senior Indebtedness and Policy Liabilities of the Company and equal in right of payment to all other Subordinated Indebtedness of the Company. The Notes will constitute Subordinated Indebtedness for purposes of the Insurance Companies Act (Canada).
Events of Default:	An Event of Default in respect of the Notes will occur if the Company becomes bankrupt or insolvent, consents to the institution of bankruptcy or insolvency proceedings against it, resolves to wind-up or liquidate, is ordered wound-up or liquidated, or makes a general assignment for the benefit of its creditors, or a receiver of a substantial portion of the Company's property is appointed. If an Event of Default has occurred and is continuing, either trustee or the holders of not less than 25% of the principal amount of the Notes may declare the principal on all outstanding Notes to be immediately due and payable. However, the holders of a majority in principal amount of the Notes by written notice to the trustees may, under certain circumstances, instruct the trustees to waive any Event of Default and/or to cancel any such declaration. There is no right of acceleration in the case of a breach in the performance of any covenant of the Company in the indenture, including a failure to pay amounts due on the Notes, although a legal action could be brought by the trustees to enforce such covenant.

20. The Company is eligible to file a short form prospectus with the Reviewing Authority and use the Shelf Procedures in respect of the Securities.

21. The Canadian Prospectus has been filed with the Reviewing Authority in the manner and within the time period required by the Shelf Procedures.

22. The statements in the Registration Statement under Part II of the registration statement on Form F-10 under the heading "Indemnification of Directors and Officers", insofar as such statements constitute statements of the laws of the Province of Ontario or the federal laws of Canada applicable therein or purport to summarize provisions of agreements or instruments, have been reviewed by us and fairly summarize the matters described therein and are accurate in all material respects.

23. The form of global certificate representing the Securities has been approved by the Company and complies with the provisions of the ICA.

24. The attributes and characteristics of the Securities conform in all material respects with the statements relating thereto contained in the Canadian Prospectus.

25. The statements in the Canadian Prospectus under the headings "ICA Restrictions and Approvals", "Constraints on Shares", "Enforceability of Civil Liabilities" and "Statutory and Contractual Rights of Withdrawal and Rescission Applicable to Canadian Investors", insofar as such statements constitute statements of Canadian federal or Ontario law, have been reviewed by us and fairly summarize the matters described therein and are accurate in all material respects.

26. The statements in the Canadian Prospectus under the heading "Additional Restrictions on Declaration of Dividends", insofar as such statements purport to summarize provisions of agreements or instruments, provide, in all material respects, a fair summary of such agreements or instruments.

A-1-4

27. The statements in the Canadian Prospectus under the heading "Description of the Notes – Ranking and Subordination" (including the summary of such section set forth under the heading "Summary – The Offering – Ranking and Substitution") which relate to the subordination provisions of the Indenture and the Securities, which provisions are governed by and construed in accordance with the laws of Ontario and the federal laws of Canada applicable therein, insofar as such statements purport to summarize provisions of agreements or instruments, provide, in all material respects, a fair summary of such agreements or instruments.

28. Subject to the assumptions and qualifications set out therein, the statements as to matters of the federal laws of Canada under the heading "Certain Canadian Federal Income Tax Considerations" in the Canadian Prospectus are accurate in all material respects.

29. All payments by the Company pursuant to the Underwriting Agreement shall be made without withholding for taxes under the Income Tax Act (Canada) provided that such payments are not in respect of services rendered in Canada.

30. No tax imposed under Part IX of the Excise Tax Act (Canada) will be payable by the Company or collectable by an Underwriter in respect of the payment of commissions as contemplated by the Underwriting Agreement to an Underwriter that is not resident of Canada, provided that such commissions are in respect of services performed by the Underwriter wholly outside of Canada and for the resale of Securities by an Underwriter to U.S. residents.

31. No stamp duty, documentary taxes or similar taxes are payable by the Company under the federal laws of Canada or the laws of the Province of Ontario in connection with the sale and delivery of the Securities pursuant to the Underwriting Agreement to the Underwriters or the resale of Securities by an Underwriter to U.S. residents.

32. A court of competent jurisdiction in the Province of Ontario (an "Ontario Court") would give effect to the choice of the law of the State of New York ("New York Law") in the Underwriting Agreement and the Indenture (to the extent the Indenture is governed by New York Law), provided that such choice of law is bona fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction) and provided that such choice of law is not contrary to "public policy", as that term is applied by an Ontario Court.  Based on the facts of which we have knowledge, in our opinion, there are no reasons under the laws of the Province of Ontario or the federal laws of Canada applicable therein for avoiding the choice of New York Law to govern the Underwriting Agreement and the Indenture (to the extent the Indenture is governed by New York Law).

33. In an action on a final and conclusive judgment in personam for a fixed sum of money of any State or Federal Court in the Borough of Manhattan, City and State of New York (a "New York Court") that is not impeachable as void or voidable under New York Law, an Ontario Court (a) would not refuse to recognize the non-exclusive jurisdiction of the court rendering such judgment on the basis of process being served on John Hancock Life

A-1-5

Insurance Company (U.S.A.) as the agent of the Company to receive service of process in the United States under the Underwriting Agreement or the Indenture provided the Company has not purported to revoke the appointment or John Hancock Life Insurance Company (U.S.A.) has not terminated the agency or otherwise rendered service on it ineffective and (b) would give effect to the provisions in the Underwriting Agreement and the Indenture whereby the Company submits to the non-exclusive jurisdiction of a New York Court.

34. If the Underwriting Agreement or the Indenture (to the extent the Indenture is governed by New York Law) are sought to be enforced in the Province of Ontario in accordance with New York Law, an Ontario Court would, to the extent specifically pleaded and proved as a fact by expert evidence, recognize the choice of New York Law and, upon appropriate evidence as to such law being adduced, apply such law to all issues that under the conflict of laws rules of the Province of Ontario are to be determined in accordance with the proper or general law of a contract, provided that none of the provisions of the Underwriting Agreement or the Indenture (to the extent those provisions are governed by New York Law), or of New York Law, are contrary to "public policy" as that term is applied by an Ontario Court; provided, however, that, in matters of procedure, the laws of the Province of Ontario will be applied, including the Limitations Act, 2002 (Ontario), and an Ontario Court will retain discretion to decline to hear such action if it is contrary to "public policy", as that term is applied by an Ontario Court, for it to do so, or if it is not the proper forum to hear such an action, or if concurrent proceedings are being brought elsewhere.  Based on the facts of which we have knowledge, in our opinion there are no reasons under the laws of the Province of Ontario or the federal laws of Canada applicable therein and no reasons, to our knowledge, with respect to the application of New York Law by an Ontario Court, for avoiding enforcement of the Underwriting Agreement or the Indenture (to the extent the Indenture is governed by New York Law), based on "public policy", as that term is applied by an Ontario Court.

35. The laws of the Province of Ontario and the federal laws of Canada applicable therein permit an action to be brought in an Ontario Court on a final and conclusive judgment in personam for a fixed sum of money of a New York Court that is subsisting and unsatisfied respecting the enforcement of the Underwriting Agreement or the Indenture and that is not impeachable as void or voidable under New York Law if: (a) 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" as such term is applied by an Ontario Court, or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada) in respect of certain judgments, laws and directives having effect on competition in Canada; (b) the enforcement of such judgment does not constitute, directly or indirectly, the enforcement of foreign revenue or penal laws; (c) the action to enforce such judgment is commenced within the applicable limitation period; and (d) a court rendering such judgment had jurisdiction over the Company as recognized by the courts of the Province of Ontario (in our opinion, submission under the provisions of the Underwriting Agreement and the Indenture to the non-exclusive jurisdiction of a New York Court will be sufficient for this purpose). 

A-1-6

Based on the facts of which we have knowledge, in our opinion there are no reasons under the laws of the Province of Ontario or the federal laws of Canada applicable therein for avoiding recognition of judgments of a New York Court under the Underwriting Agreement or the Indenture based on "public policy", as that term is applied by an Ontario Court.

(5) The statements in the Prospectus under the headings "Description of the Notes" in the Prospectus Supplement and "Description of Debt Securities" in the Base Prospectus, when taken together, and the statements in the Time of Sale Information under the headings "Description of the Notes" in the Prospectus Supplement and "Description of Debt Securities" in the Base Prospectus, when taken collectively with the statements contained in the final term sheet, insofar as such statements purport to summarize certain provisions of the Indenture and the Securities, are accurate in all material respects; provided that we express no opinion in this paragraph 5 with respect to statements relating to the subordination provisions of the Indenture and the Securities, which provisions are governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

(6) The Company is not, and, on the date hereof after giving effect to the offering and sale of the Securities in the manner contemplated in the Underwriting Agreement and the Prospectus, will not be, required to be registered as an "investment company" (as defined in the 1940 Act) under the 1940 Act.

(the "Agent") for the purposes described in Section 18 of the Underwriting Agreement and Section 115 of the Indenture, and service of process effected on the Agent in the manner set forth therein will be effective to confer valid personal jurisdiction over the Company.  In rendering the foregoing opinion, we express no opinion as to whether any such court would accept such jurisdiction.

A-2-4

(10) The execution and delivery by the Company of the Underwriting Agreement and the Base Indenture did not, the execution and delivery by the Company of the Supplemental Indenture will not, and the issuance and sale today by the Company of the Securities in accordance with the terms of the Indenture and the Underwriting Agreement will not, violate (a) any existing United States Federal or New York State law, rule or regulation known to us to be applicable to the Company, (b) any existing judgment, order or decree known to us to be binding upon the Company of any United States Federal or New York State court or other governmental authority, or (c) the subordinated note guarantee listed in Schedule B hereto to which the Company is a party; provided that we express no opinion in this paragraph 10 with respect to United States Federal or state securities laws

Our opinions set forth above are subject to the effects of (i) bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization and moratorium laws, and other similar laws relating to or affecting creditors' rights or remedies generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), (iii) concepts of good faith, reasonableness and fair dealing, and standards of materiality and (iv) limitations on the validity or enforceability of indemnification, contribution or exculpation under applicable law (including court decisions) or public policy.

Without limiting the foregoing, we express no opinion as to the validity, binding effect or enforceability of any provision of the Indenture or the Securities that purports to (i) waive, release or vary any defense, right or privilege of, or any duties owing to, any party to the extent that such waiver, release or variation may be limited by applicable law, (ii) constitute a waiver of inconvenient forum or improper venue, (iii) relate to the subject matter jurisdiction of a court to adjudicate any controversy, (iv) grant a right to collect any amount that a court determines to constitute post-judgment interest or a penalty or forfeiture, (v) grant any right of set-off with respect to any contingent or unmatured obligation, (vi) maintain or impose any obligation to pay any amount in U.S. dollars, or specify any rate or method of exchange, where a final judgment concerning such obligation is rendered in another currency, or maintain or impose any obligation to pay any amount in a foreign currency, or specify any rate or method of exchange, where a final judgment concerning such obligation is rendered in U.S. dollar, or (vii) provide for liquidated damages or otherwise specify or limit damages, liabilities or remedies.  In addition, the enforceability of any provision in the Indenture or the Securities to the effect that (x) the terms thereof may not be waived or modified except in writing, (y) the express terms thereof supersede any inconsistent course of dealing, performance or usage of trade or (z) certain determinations made by one party shall have conclusive effect, may be limited under certain circumstances. Our opinions in paragraphs 2, 4 and 9 above with respect to the choice of law and choice of forum provisions of the Indenture, the Securities and the Underwriting Agreement, as the case may be, are given in reliance on, and are limited in scope to, Sections 5-1401 and 5-1402 of the General Obligations Law of the State of New York, and we express no opinion with respect to any such provision insofar as it exceeds such scope.

For purposes of the opinion set forth in paragraph 10 as to any judgment, order or decree referred to therein, we have only endeavored, to the extent we have believed necessary, to determine from lawyers currently in our firm who have performed substantive legal services for

A-2-5

the Company whether such services involved substantive attention in the form of legal representation concerning any judgment, order or decree of the nature referred to in such paragraph 10.  We have not made any other review, search or investigation, whether of any public files or records or otherwise, with respect to such opinion.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of New York and the Federal laws of the United States of America, each as currently in effect, in each case that in our experience are normally applicable to transactions of the type contemplated by the Underwriting Agreement and the Indenture without regard to the particular nature of the business conducted by the Company.

The opinions expressed herein are solely for the benefit of the Underwriters and, without our prior written consent, neither our opinions nor this opinion letter may be disclosed to or relied upon by any other person, except that the Trustee may rely upon paragraphs 2, 3 and 4 of this letter as if such paragraphs were addressed to the Trustee.  This opinion letter is limited to, and no opinion is implied or may be inferred beyond, the matters expressly stated herein.  The opinions expressed herein are rendered only as of the date hereof, and we assume no responsibility to advise the Underwriters of facts, circumstances, changes in law, or other events or developments that hereafter may occur or be brought to our attention and that may alter, affect or modify the opinions expressed herein.

Very truly yours,

representatives of the several underwriters named therein (the representatives and such other underwriters, collectively, the "Underwriters").  The Securities will be issued pursuant to the Subordinated Indenture, dated as of February [●], 2017 (the "Base Indenture"), between the Company and The Bank of New York Mellon, as U.S. trustee (the "U.S. Trustee"), and BNY Trust Company of Canada, as Canadian trustee (together with the U.S. Trustee, the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of February [●], 2017, between the Company and the Trustee (the "Supplemental Indenture"; the Base Indenture, as supplemented and amended by the Supplemental Indenture being referred to herein as the "Indenture"). We are delivering this letter to you pursuant to Section 5(e) of the Underwriting Agreement.

In so acting, we have reviewed the registration statement on Form F-10 (Registration No. 333-208442), as amended, of the Company filed with the Securities and Exchange Commission (the "SEC") pursuant to the Securities Act of 1933, as amended (the "1933 Act"), the Time of Sale Information (as defined below) and the final prospectus supplement, dated February [●], 2017 (the "Prospectus Supplement"), relating to the Securities, in the form filed with the SEC pursuant to General Instruction II.L of Form F-10.  As used herein, the term "Registration Statement" means such registration statement, as amended, on the date such registration is deemed to be effective pursuant to Rule 430B under the 1933 Act for purposes of liability under Section 11 of the 1933 Act of the Company and the Underwriters (which, for purposes hereof, is February [●], 2017, the "Effective Date"), including the information deemed to be a part of such registration statement as of the Effective Date pursuant to Rule 430B under the 1933 Act.  The term "Base Prospectus" means the base prospectus, dated December 17, 2015, filed as part of the Registration Statement.  The term "Preliminary Prospectus Supplement" means the preliminary prospectus supplement, dated February [●], 2017, relating to the Securities, in the form filed with the SEC pursuant to General Instruction II.L of Form F-10.  The term "Time of Sale Information" means, collectively, the Base Prospectus, the Preliminary Prospectus Supplement and the final term sheet in the form filed with the SEC pursuant to Rule 433 under the 1933 Act and attached hereto as Schedule A.  The term "Prospectus" means the Base Prospectus as supplemented by, and together with, the Prospectus Supplement.

We have reviewed and discussed the contents of the Registration Statement, the Time of Sale Information and the Prospectus with certain officers and employees of the Company and its subsidiaries, their counsel, representatives of the Company's independent accountants and representatives of the Underwriters and their counsel.  We have not ourselves checked the accuracy, completeness or fairness of, or otherwise verified, and we are not passing upon and assume no responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the Time of Sale Information or the Prospectus, or the documents incorporated by reference in any of the foregoing, and have made no independent check or verification thereof, except as and to the extent expressly set forth in paragraphs 5 and 7 of our opinion letter dated as of the date hereof addressed to you and delivered to you pursuant to the Underwriting Agreement.  We have also assumed (a) the accuracy of the representations and warranties of the Company set forth in Section 1(b) of the Underwriting Agreement that the Company meets the general eligibility requirements for use of Form F-10 under the 1933 Act and (b) that each document filed by the Company with the securities regulatory authorities in

A-3-2

Canada and incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement and the Prospectus conformed when so filed to the requirements of the Canadian Securities Laws (as defined in the Underwriting Agreement).

On the basis of the foregoing, we advise you as follows:

(i)The Registration Statement, as of the Effective Date, and the Prospectus, as of the date of the Prospectus Supplement, appeared to us on their face to be appropriately responsive in all material respects to the requirements as to form of the 1933 Act and the applicable rules and regulations of the SEC thereunder; except that we express no view as to (a) the financial statements, the related notes and schedules, and other financial and accounting or statistical data or information contained in or omitted from the Registration Statement or the Prospectus; (b) the statement of eligibility of the Trustee under the Indenture; or (c) Regulation S-T.

(ii)No facts have come to our attention that have caused us to believe that (a) the Registration Statement, as of the Effective Date, contained any 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; (b) the Time of Sale Information, as of [●] p.m., New York City time, on February [●], 2017, contained any 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 (c) the Prospectus, as of the date of the Prospectus Supplement and as of the date and time of the delivery of this letter, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that in each case we express no belief as to (1) the financial statements, the related notes and schedules, and other financial and accounting or statistical data or information contained in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus; (2) the report of management's assessment of the effectiveness of internal control over financial reporting or the auditor's attestation report thereon in the Registration Statement, the Time of Sale Information or the Prospectus; or (3) the statement of eligibility of the Trustee under the Indenture.

(iii)Based exclusively on our review of the SEC's Internet site page of stop orders at http://www.sec.gov/litigation/stoporders.shtml and the notice of effectiveness of the Registration Statement posted on the SEC's EDGAR database, the Registration Statement has become effective under the 1933 Act pursuant to Rule 467(b) and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for such purpose are pending before the SEC.

This letter is solely for the benefit of the Underwriters and, without our prior written consent, neither our beliefs nor this letter may be disclosed to or relied upon by any other
