(j) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the U.S. Final Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the reasonable opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and the Canadian Securities Commissions and furnish, at its own expense, to the Underwriters and to any dealer (whose names and addresses you shall furnish to the Company) upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply in material respects with applicable law. (k) If any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Canadian Preliminary Prospectus to make the statements therein, in the light of the

(l) If any event shall occur or condition exist as a result of which it is necessary to amend or supplement any marketing materials in order to make the statements therein, in the light of the circumstances, not misleading or to correct any misrepresentation contained therein, or if, in the reasonable opinion of counsel for the Underwriters, it is necessary to amend or supplement the marketing materials to comply with Canadian Securities Laws, forthwith to prepare, file or deliver, as applicable, with the Canadian Securities Commissions and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the marketing materials so that the statements in the marketing materials as so amended or supplemented will not, in the light of the circumstances when the marketing materials are delivered to a prospective purchaser, be misleading or contain a misrepresentation, or so that the marketing materials, as amended or supplemented, will comply with Canadian Securities Laws. (m) If any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectuses (or one of them) in order to make the statements therein, in the light of the circumstances, not misleading or to correct any misrepresentation contained therein, or if, in the reasonable opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectuses (or one of them) to comply with Canadian Securities Laws, forthwith to prepare, file or deliver, as applicable, with the Commission and the Canadian Securities Commissions and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company) to which Shares may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectuses (or one of them) so that the statements in the Prospectuses (or one of them) as so amended or supplemented will not, in the light of the circumstances be misleading or contain a misrepresentation or so that the Prospectuses, as amended or supplemented, will comply with Canadian Securities Laws. (n) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction where it is not presently qualified or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject. (o) The Company shall pay, and shall indemnify and hold the Underwriters harmless against, any stamp, issue, registration, documentary, sales, transfer or other similar taxes, governmental charges or duties, including any interest and penalties with respect thereto, imposed under the laws of Canada or any political sub-division or taxing authority thereof or therein that is payable in connection with (i) the execution, delivery, consummation or enforcement of this Agreement, (ii) the creation, allotment and issuance of the Shares, (iii) the sale and delivery of the Shares to the Underwriters or purchasers procured by the Underwriters, or (iv) the resale and delivery of the Shares by the Underwriters in the manner contemplated herein. (p) To make generally available to the Company’s security holders and to you (it being understood that filings on SEDAR or XXXXX satisfy this requirement) as soon as practicable earnings statements covering four fiscal quarters of the Company occurring after the date of this Agreement which shall

20 satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder. (q) To use its best efforts to have the Shares accepted for listing on the NYSE and the TSX and to file with such exchanges all documents and notices required by such exchanges of issuers that have securities that are listed on such exchanges. (r) If requested by the Managers, to prepare a final term sheet relating to the Offering, containing only information that describes the final terms of the Offering in a form consented to by the Managers, and to file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the Offering. (s) The Company will deliver to each Underwriter (or its agent) upon such Underwriter’s request, 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 each Underwriter may reasonably request in connection with the verification of the foregoing Certification (t) All sums payable to an Underwriter shall be considered exclusive of any value added, goods and services, or similar taxes. Where the Company is obliged to pay such tax on any amount payable hereunder to an Underwriter, the Company shall in addition to the sum payable hereunder pay an amount equal to any applicable value added or similar tax. (u) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all reasonable expenses incident to the Offering (other than underwriting discounts or commissions which shall be borne by the Company in respect of Shares), including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration, qualification and delivery of the Shares under the Securities Act and the Canadian Securities Laws and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any base shelf prospectus, any preliminary prospectus (including the Canadian Preliminary Prospectus), the Time of Sale Prospectus, the Prospectuses, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company, any marketing materials, and amendments and supplements to any of the foregoing, including the filing fees payable to the Commission and the Canadian Securities Commissions relating to the Shares, all translation costs associated therewith, all printing and typesetting costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to and the sale by the Underwriters in the manner contemplated by this Agreement, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky memorandum or filing fees in connection with the offer and sale of the Shares under state securities laws, including reasonable fees and disbursements of counsel to the Underwriters incurred in connection therewith, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the Offering by FINRA (the fees of counsel in (iii) and (iv) not to exceed $35,000), (v) all costs and expenses incident to listing the Shares on the NYSE and the TSX, (vi) the cost of printing any certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, and expenses associated with the production of road show slides in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, (ix) the document production charges and expenses associated with printing this Agreement, (x) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section and (xi) all applicable sales taxes, to the

21 extent not creditable or refundable, on any of the foregoing. It is understood, however, that except as provided in Section 6, this Section, Section 8 entitled “Indemnity and Contribution” and the last paragraph of Section 10 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make. (v) The Company also covenants with each Underwriter that, without the prior written consent of the Managers identified in Schedule I with the authorization to release this lock-up on behalf of the Underwriters, it will not, and will not publicly disclose the intention to, during the restricted period set forth in Schedule I hereto (the “Restricted Period”), (1) issue, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Subject Shares or any securities convertible into or exercisable or exchangeable for Subject Shares or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Subject Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Subject Shares or such other securities, in cash or otherwise or (3) file any registration statement with the Commission or prospectus with the Canadian Securities Commissions relating to the offering of any Subject Shares or any securities convertible into or exercisable or exchangeable for Subject Shares. The foregoing sentence shall not apply to (a) the Shares to be sold by the Company hereunder, (b) the issuance of incentive compensation or equity (including Subject Shares) in accordance with the terms and conditions of the benefit plans described in the Registration Statement, the Time of Sale Prospectus and the Prospectuses, as such benefit plans may be amended or restated, (c) any Subject Shares issued pursuant to any non-employee director stock plan or dividend reinvestment plan referred to in the Registration Statement, the Time of Sale Prospectus and the Prospectuses, (d) Subject Shares or other securities issued in connection with an acquisition or a transaction that includes a commercial relationship (including joint ventures, collaborations, partnership or other strategic acquisitions, but excluding stock options); provided (i) that the aggregate amount of Subject Shares (the “Transaction Shares”) issued in connection with such transactions, not taking into account Subject Shares issuable in connection with transactions disclosed by the Company prior the date hereof in respect of which a definitive agreement has been entered into as at the date hereof (which shall not constitute Transaction Shares), does not exceed 10% of the total shares outstanding of the Company upon consummation of the Offering and (ii) in the case of any such issuance in connection with such transactions prior to the expiration of the Restricted Period, the issuee shall sign and deliver a lock-up letter substantially in the form of Exhibit A hereto in respect of at least 50% of the Transaction Shares received by such issuee, or (e) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act or similar plan under Canadian securities laws for the transfer of Subject Shares, provided that (i) such plan does not provide for the transfer of Subject Shares during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Subject Shares may be made under such plan during the Restricted Period. In addition, the Company covenants to cause each of the parties listed on Annex A hereto to enter into the “lock-up” agreements, each substantially in the form of Exhibit A hereto, on or before the Closing Date. Covenants of the Underwriters. Each Underwriter, severally and not jointly, covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter. Each Underwriter, severally and not jointly, agrees that (i) it has not made and will not make use of any materials that would constitute marketing materials relating to the Offering except marketing materials identified in Schedule I or marketing materials prepared in accordance with the terms and conditions hereof, and (ii) it will comply with

22 Canadian securities laws in connection with the distribution of the Shares and the provision of any marketing materials or standard term sheets (as defined in NI 41-101). 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 and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act 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, but excluding loss of profits and other consequential damages) (collectively, “Damages”) caused by any misrepresentation or untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus (including the Canadian Preliminary Prospectus), the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any marketing materials, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show, or the Prospectuses or any amendment or supplement thereto, or caused by any misrepresentation or omission or alleged misrepresentation or 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 Damages are caused by any such misrepresentation or untrue statement or omission or alleged misrepresentation or untrue statement or omission based upon (i) information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in paragraph (b) below. The rights of indemnity contained in this paragraph will not inure to the benefit of an indemnified party in respect of a claim if the person asserting the claim, other than a person to which Subject Shares were offered and sold in the United States, was not provided by or on behalf of the Underwriters with a copy furnished promptly by the Company of any Prospectus or any amendment or supplement thereto which would have corrected any misrepresentation which is the basis of the claim and which was required under Canadian Securities Laws to be delivered to that person by the Underwriters. (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company 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 you expressly for use in the Registration Statement, any preliminary prospectus (including the Canadian Preliminary Prospectus), the Time of Sale Prospectus, any issuer free writing prospectus, marketing materials, road show, or the Prospectuses or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectuses furnished on behalf of each Underwriter: the information contained in the twelfth through fifteenth paragraphs under the caption “Plan of Distribution” in the Time of Sale Prospectus and the U.S. Final Prospectus. (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 reasonable 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 reasonable 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

23 retention of such counsel, (ii) the indemnifying party has failed within a reasonable time to retain counsel for the indemnified party in accordance with the preceding sentence, or (iii) 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 (i) the fees and expenses of more than one separate firm (in addition to any local counsel, which shall include counsel in each of the United States and Canada in the case of a matter involving U.S. and Canadian law) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel, which shall include counsel in each of the United States and Canada in the case of a matter involving U.S. and Canadian law) for 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 such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Manager authorized to appoint counsel under this Section set forth in Schedule I hereto. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. 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 reasonable 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 60 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 (i) such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding 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 an indemnified party. (d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any Damages 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 Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the Offering or (ii) if the allocation provided by clause 8(e)(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(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such Damages and 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 shall be deemed to be in the same respective proportions as the net proceeds from the Offering (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 Shares set forth in the U.S. Final Prospectus. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference

24 to, among other things, whether the misrepresentation or untrue statement of a material fact or alleged misrepresentation or 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 misrepresentation, statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares 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 Damages 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 Shares 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 misrepresentation or untrue statement or alleged misrepresentation or untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 8(e) 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. (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 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 Shares. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or any Option Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the NYSE, the NYSE American, the Nasdaq or the TSX, (ii) trading of any securities of the Company shall have been suspended on the NYSE or TSX, (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 U.S. Federal or New York State or Canadian authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectuses. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or

25 refused to purchase on such date; provided that in no event shall the number of Shares 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 number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter and the Company, except in respect of any liability which may have arisen or may arise under Section 8. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectuses or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non- defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement (other than by reason of a default of one of the Underwriters), or if for any reason (other than by reason of a default of one of the Underwriters) the Company shall be unable to perform its obligations under this Agreement (which, for purposes of this paragraph, should not include termination pursuant to Section 9(i), (iii), (iv) or (v)), the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the Offering contemplated hereunder. Submission to Jurisdiction; Appointment of Agents for Service. (a) The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in the Borough of Manhattan in The City of New York (the “Specified Courts”) over any suit, action or proceeding arising out of or relating to this Agreement, the Prospectuses, the Registration Statement or the Offering (each, a “Related Proceeding”). The Company 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 Related Proceeding brought in such a court and any claim that any such Related Proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding in respect of its obligations under this Agreement. (b) The Company hereby irrevocably appoints Corporation Service Company with offices at 000 Xxxxxx Xxxxx Xxxxx, Xxxxxx of Xxx Xxxxxx, Xxxxxxxxxx, Xxxxxxxx 00000, as its agent for service of process in any Related Proceeding and agrees that service of process in any such Related Proceeding may be made upon it at the office of such agent. The Company waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. The Company represents and warrants that such agent has agreed to act as the agent for service of process, and the Company 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 for a period of seven years from the date of this Agreement.

26 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 State. (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.
