(a) The Company represents and agrees that, without the prior consent of the Underwriters, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; the Selling Shareholder represents and agrees that, without the prior consent of the Company and the Underwriters, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; and each Underwriter represents and agrees that, without the prior consent of the Company and the Underwriters, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Company and the Underwriters is listed on Schedule II(a) hereto; the Company represents and agrees that, without the prior consent of the Underwriters, it has not made and will not make use of any materials that would constitute marketing materials (as defined in NI 41-101) relating to the Shares, the Company or the offering; the Selling Shareholder represents and agrees that, without the prior consent of the Company and the Underwriters, it has not made and will not make use of any materials that would constitute marketing materials (as defined in NI 41-101) relating to the Shares, the Company of the offering; and each Underwriter represents and agrees that, without the prior consent of the Company and the Underwriters, it has not made and will not make use of any materials that would constitute marketing materials (as defined in NI 41-101) relating to the Shares, the Company or the offering; any such materials the use of which has been consented to by the Company and the Underwriters are the marketing materials (as defined in NI 41-101) listed on Schedule II(d) hereto and the Underwriters agree (severally and not jointly) to comply with Canadian Securities Laws and laws concerning the French language in Quebec in connection with the provision of any marketing materials or standard term sheet (each as defined in NI 41-101) to prospective purchasers of the Shares;

(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any electronic road show; the Company has complied and will comply with its requirements

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the U.S. Pricing Prospectus or the Prospectuses or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through the Underwriters or their counsel expressly for use therein or by the Selling Shareholder or its counsel expressly for use therein in connection with the disclosure required by Form F-3 or Canadian Securities Laws.

7. The Company covenants and agrees with the several Underwriters: that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Shares under the Act, the qualification of the Shares for distribution by prospectus under Canadian Securities Laws and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any U.S. Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectuses and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of producing any Agreement among Underwriters, this Agreement, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (iii) all expenses in connection with the qualification of the Shares for offering and sale under U.S. state laws and Canadian Securities Laws as provided in Section 5(b) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with any Blue Sky survey undertaken (such fees and expenses referenced in clause (ii) and (iii) not to exceed $5,000.00); (iv) all fees and expenses in connection with listing the Shares on the NYSE and the TSX; (v) the filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, any required review by FINRA of the terms of the sale of the Shares (such fee and expenses not to exceed $5,000.00); and (vi) the cost of preparing share certificates; if applicable (vii) the cost and charges of any transfer agent or registrar, and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. The Selling Shareholder shall pay or cause to be paid all taxes incident to the sale and delivery of the Shares to be sold by the Selling Shareholder to the Underwriters hereunder. In connection with the preceding sentence, the Underwriters agree to pay New York State stock transfer tax, and the Selling Shareholder agrees to reimburse the Underwriters for associated carrying costs if such tax payment is not rebated on the day of payment and for any portion of such tax payment not rebated. It is understood, however, that the Company shall bear, and the Selling Shareholder shall not be required to pay or to reimburse the Company for, the cost of any other matters not directly relating to the sale and purchase of the Shares pursuant to this Agreement (other than, in the case of the Selling Shareholder, the underwriting commissions in respect of the Shares sold by the Selling Shareholder hereunder), and that, except as provided in this Section, and Sections 9 and 12 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, and any advertising expenses connected with any offers they may make.

(k) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization”, as defined in Section 3(a)(62) of the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities;

(l) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the NYSE or the TSX; (ii) a suspension or material limitation in trading in the Company’s securities on the NYSE or the TSX; (iii) a general moratorium on commercial banking activities in the United States or Canada declared by the relevant authorities, or a material disruption in commercial banking or securities settlement or clearance services in the United States or Canada; (iv) the outbreak or escalation of hostilities involving the United States or Canada or the declaration by the United States or Canada of a national emergency or war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or Canada or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment such as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at the Time of Delivery on the terms and in the manner contemplated in the Prospectuses;

(m) Any steps required to be completed prior to the Time of Delivery, including the conversion of the Selling Shareholder’s multiple voting shares, shall be completed; the Shares will be duly and validly issued upon conversion of multiple voting shares in the capital of the Company or otherwise be legally and beneficially owned by the Selling Shareholder and be fully paid and non-assessable and available for transfer to the Underwriters;

(r) The Selling Shareholder will have delivered to you, on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as you may reasonably request in connection with the verification of the foregoing certification; and

(s) The Selling Shareholder will have delivered to you prior to or at the Time of Delivery a properly completed and executed United States Treasury Department Form W-9 or W-8BEN-E, establishing a complete exemption from United States backup withholding tax.

9. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act, Canadian 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, any U.S. Preliminary Prospectus, the U.S. Pricing Prospectus or the U.S. Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) a misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws) contained in the Canadian Preliminary Prospectus, the Canadian Prospectus or any amendment or supplement thereto; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter 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 or misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws) made in the Registration Statement, any U.S. Preliminary Prospectus, Canadian Preliminary Prospectus, Canadian Prospectus, the U.S. Pricing Prospectus or the Prospectuses, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information (as defined below) or the Selling Shareholder Information.

(b) The Selling Shareholder will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act, Canadian 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, any U.S. Preliminary Prospectus, the U.S. Pricing Prospectus, or the U.S. Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) a misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws) contained in the Canadian Preliminary Prospectus, the Canadian Prospectus or any amendment or supplement thereto; in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission or misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws), as the case may be, was made in the Registration Statement, any U.S. Preliminary Prospectus, Canadian Preliminary Prospectus, Canadian Prospectus, the U.S. Pricing Prospectus or the Prospectuses, or any amendment or supplement thereto or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Selling Shareholder Information; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the liability of the Selling Shareholder pursuant to this subsection (b) shall not exceed the aggregate net proceeds after underwriting commissions, but before deducting expenses, received by the Selling Shareholder from the Underwriters for the Shares sold by the Selling Shareholder hereunder.

(c) The Underwriters, severally and not jointly, will indemnify and hold harmless the Company and the Selling Shareholder against any losses, claims, damages or liabilities to which the Company or the Selling Shareholder may become subject, under the Act, Canadian 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, any U.S. Preliminary Prospectus, the U.S. Pricing Prospectus or the U.S. Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) a misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws) contained in the Canadian Preliminary Prospectus, the Canadian Prospectus or any amendment or supplement thereto; in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission or misrepresentation or alleged misrepresentation (as that term is defined under applicable Canadian Securities Laws), as the case may be, was made in the Registration Statement, any U.S. Preliminary Prospectus, Canadian Preliminary Prospectus, Canadian Prospectus, the U.S. Pricing Prospectus or the Prospectuses, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter or its counsel expressly for use therein; and will reimburse the Company and the Selling Shareholder for any legal or other expenses reasonably incurred by the Company or the Selling Shareholder in connection with investigating or defending any such action or claim as such expenses are incurred. The Company acknowledges that the statements in any Canadian Prospectus set forth in the tenth, eleventh and twelfth paragraphs under the heading “Plan of Distribution” and in any U.S. Prospectus set forth in the eleventh, twelfth and thirteenth paragraphs under the heading “Underwriting” (collectively, the “Underwriter Information”), constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Registration Statement, any U.S. Preliminary Prospectus, Canadian Preliminary Prospectus, Canadian Prospectus, the U.S. Pricing Prospectus or the Prospectuses, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) of this Section 9 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. 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.

(e) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein (other than as a result of the limitations imposed on indemnification described in such preceding subsections of this Section 9), 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 and the Selling Shareholder on the one hand and the Underwriters on the other from the offering of the Shares. 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 (d) 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 and the Selling Shareholder 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 and the Selling Shareholder 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 and the Selling Shareholder bear to the total underwriting commissions or discounts received by the Underwriters, in each case described in 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 or the Selling Shareholder 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, the Selling Shareholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). 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 (e) 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 (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. In no event shall the aggregate liability of the Selling Shareholder under Section 9(b) and this Section 9(e) exceed the limit set forth in Section 9(b). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) The obligations of the Company and the Selling Shareholder under this Section 9 shall be in addition to any liability which the Company and the Selling Shareholder may otherwise have and shall extend, upon the same terms and conditions, to each officer, director or employee of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer, director or employee of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company or the Selling Shareholder within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase the Shares that it has agreed to purchase hereunder at the Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Shareholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Shareholder that you have so arranged for the purchase of such Shares, or the Company or the Selling Shareholder notifies you that it has so arranged for the purchase of such Shares, you or the Company or the Selling Shareholder 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 or supplements to the Registration Statement or the Prospectuses which in your 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 Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Shareholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at the Time of Delivery, then the Company and the Selling Shareholder shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at the Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares 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 Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Shareholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be purchased at the Time of Delivery, or if the Company and the Selling Shareholder shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Shareholder, except for the expenses to be borne by the Company, the Selling Shareholder and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Shareholder and 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 or any controlling person of any Underwriter, or the Company, or the Selling Shareholder, or any officer or director or controlling person of the Company, or any controlling person of the Selling Shareholder, and shall survive delivery of and payment for the Shares.

12. If this Agreement shall be terminated pursuant to Section 10 hereof or as a result of a failure to satisfy the condition specified in Section 8(l) hereof, neither the Company nor the Selling Shareholder shall then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Company and the Selling Shareholder as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Shareholder shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

In all dealings hereunder, you 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 you jointly; and in all dealings with the Selling Shareholder hereunder, you and the Company shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of the Selling Shareholder made or given by the Selling Shareholder.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Shareholder, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

15. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and the Selling Shareholder and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company, the Selling Shareholder or any Underwriter, and 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 Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

16. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business and chartered banks in Canada are open for business in Toronto, Ontario.

17. The Company and the Selling Shareholder acknowledge and agree that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Selling Shareholder, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Selling Shareholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Selling Shareholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Selling Shareholder on other matters) or any other obligation to the Company or the Selling Shareholder except the obligations expressly set forth in this Agreement and (iv) the Company and the Selling Shareholder has consulted its own legal and financial advisors to the extent it deemed appropriate. Each of the Company and the Selling Shareholder agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Selling Shareholder, in connection with such transaction or the process leading thereto.

18. If the Selling Shareholder shall fail at the Time of Delivery to sell the number of Shares that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any non-defaulting party; provided, however, that the provisions of Sections 7, 9 and 11 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Selling Shareholder from liability, if any, in respect of such default.

19. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Selling Shareholder and the Underwriters, or any of them, with respect to the subject matter hereof.

20. The Company, the Selling Shareholder and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

21.

22. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(b) Each of the Company and the Selling Shareholder hereby submits to the exclusive jurisdiction of the U.S. federal and New York state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the Company and the Selling Shareholder irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit or proceeding in such courts. Each of the Company and the Selling Shareholder agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon each of the Company and the Selling Shareholder and may be enforced in any court to the jurisdiction of which the Company or the Selling Shareholder is subject by a suit upon such judgment.

(c) The Company irrevocably appoints Arnold & Porter Kaye Scholer LLP, 250 East 55th Street, New York, NY 10019-9710, Attention: Managing Attorney, as its authorized agent in the United States upon which process may be served in any such suit or proceeding, and agrees that service of process upon such authorized agent, and written notice of such service to the Company by the person serving the same to the address provided in this Section 24, shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company hereby represents and warrants that such authorized agent has accepted such appointment and has agreed to act as such authorized agent for service of process.

The Selling Shareholder further agrees to take any and all action as may be necessary to maintain such designation and appointment of such authorized agent in full force and effect for a period of seven years from the date of this Agreement.

24. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the Business Day preceding that on which final judgment is given. The obligation of the Company with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first Business Day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in

accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company an amount equal to the excess of the dollars purchased over the sum originally due to such Underwriter or controlling person hereunder.

If the foregoing is in accordance with your understanding, please sign and return to us counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters, the Company and the Selling Shareholder. 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 and the Selling Shareholder for examination, upon request, but without warranty on your part as to the authority of the signers thereof.

Re:

Celestica Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you (the “Underwriters”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) with Celestica Inc., an Ontario corporation (the “Company”), and Onex Corporation (the “Selling Shareholder”), providing for a public offering (the “Public Offering”) of subordinate voting shares (the “Subordinate Voting Shares”) of the Company (the “Shares”) pursuant to (i) an automatic shelf registration statement on Form F-3ASR (File No. 333-273467) filed with the Securities and Exchange Commission (the “SEC”) as supplemented by a prospectus supplement and (ii) a short form base shelf prospectus for the Province of Quebec and an amended and restated final short form base shelf prospectus for all other provinces and territories of Canada, both as supplemented by a final prospectus supplement to be filed with the Canadian securities regulatory authorities in each of the provinces and territories of Canada. Capitalized terms used but not defined herein shall have the meanings set forth in the Underwriting Agreement.

In consideration of the agreement by the Underwriters to purchase the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 45 days after the date of the Underwriting Agreement (such period, the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, without the prior written consent of the Underwriters (i) offer, sell, contract to sell, pledge, grant any option, right or warrant to purchase, purchase any option or contract to sell, lend or otherwise transfer or dispose of any Subordinate Voting Shares of the Company, or any options or warrants to purchase any Subordinate Voting Shares of the Company, or any securities convertible into, exchangeable for or that represent the right to receive Subordinate Voting Shares of the Company (such Subordinate Voting Shares of the Company, options, rights, warrants or other securities, collectively, “Lock-Up Securities”) other than, for the avoidance of doubt, the conversion of the Selling Shareholder’s multiple voting shares into Subordinate Voting Shares in connection with this transaction, including without limitation any such Lock-Up Securities now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or

which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Subordinate Voting Shares of the Company or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”), (iii) make any demand for or exercise any right with respect to the registration of any Lock-Up Securities or (iv) otherwise publicly announce any intention to engage in or cause any action, activity, transaction or arrangement described in clause (i), (ii) or (iii) above.

(b)

enter into a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act relating to the transfer, sale or other disposition of the undersigned’s Lock-Up Securities, if then permitted by the Company, provided that none of the securities subject to such plan may be transferred, sold or otherwise disposed of until after the expiration of the Lock-Up Period and no public announcement, report or filing under the Exchange Act, or any other public filing, report or announcement, shall be required or shall be voluntarily made regarding the establishment of such plan during the Lock-Up Period; and

(c)

transfer the undersigned’s Lock-Up Securities pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the Board of Directors of the Company and made to all holders of the Company’s capital stock involving a Change of Control of the Company (for purposes hereof, “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons, of shares of capital stock if, after such transfer, such person or group of affiliated persons would hold at least a majority of the outstanding voting securities of the Company (or the surviving entity)); provided that in the event that such tender offer, merger, consolidation or other similar transaction is not completed, the undersigned’s Lock-Up Securities shall remain subject to the provisions of this Lock-Up Agreement.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Shares the undersigned may purchase in the Public Offering.

The undersigned now has, and, except as contemplated by clauses (a) and (c) of the third paragraph of this Lock-Up Agreement, for the duration of this Lock-Up Agreement will have, good and marketable title to the undersigned’s Lock-Up Securities, free and clear of all liens, encumbrances and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Lock-Up Securities except in compliance with the foregoing restrictions.

The undersigned acknowledges and agrees that none of the Underwriters has made any recommendation or provided any investment or other advice to the undersigned with respect to this Lock-Up Agreement or the subject matter hereof, and the undersigned has consulted its own legal, accounting, financial, regulatory, tax and other advisors with respect to this Lock-Up Agreement and the subject matter hereof to the extent the undersigned has deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may have provided or hereafter provide to the undersigned in connection with the Public Offering a Form CRS and/or certain other disclosures as contemplated by Regulation Best Interest, the Underwriters have not made and are not making a recommendation to the undersigned to enter into this Lock-Up Agreement or to transfer, sell or dispose of, or to refrain from transferring, selling or disposing of, any Subordinate Voting Shares of the Company, and nothing set forth in such disclosures or herein is intended to suggest that any Underwriter is making such a recommendation.

The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement.
