The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company by the Representative by or on behalf of the Underwriters specifically for inclusion therein, which information the parties hereto agree is limited to the Underwriters’ Information (as defined in Section 18).

(f) The Company represents and agrees that it has not made and, unless it obtains the prior consent of the Representative, it will not, make any offer relating to the Offered Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the U.S. Securities Act; provided that the prior written consent and approval of the Representative hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectus(es) included in Schedule B hereto. The Company will, pursuant to reasonable procedures developed in good faith, comply with Canadian and United States legending requirements applicable to Issuer Free Writing Prospectuses and retain copies of each Issuer Free Writing Prospectus that is not filed with the SEC in accordance with Rule 433 under the Securities Act.

(h) To the extent not available on the SEC’s EDGAR system, SEDAR or any successor system to either of them, to deliver promptly to the Representative, such number of the following documents as the Representative shall reasonably request: (i) conformed copies of the Registration Statement as originally filed with the SEC (in each case excluding exhibits), (ii) each Issuer Free Writing Prospectus, (iii) the Prospectuses (the delivery of the documents referred to in clauses (i), (ii) and (iii) of this paragraph (e) to be made not later than 10:00 A.M., Toronto time, on the second business day following the execution and delivery of this Agreement), (v) conformed copies of any amendment to the Registration Statement (excluding exhibits), (vi) any amendment or supplement to the General Disclosure Package, the Prospectuses or the Amended Prospectuses (the delivery of the documents referred to in clauses (v) and (vi) of this paragraph (e) to be made not later than 10:00 A.M., Toronto time, on the second business day following the date of such amendment or supplement) and (vii) any document incorporated by reference in the General Disclosure Package, the Prospectuses or the Amended Prospectuses (excluding exhibits thereto) (the delivery of the documents referred to in clause (vi) of this paragraph (e) to be made not later than 10:00 A.M., Toronto time, on the second business day following the date of such document).

(i) To make generally available to its shareholders as soon as practicable, but in any event not later than eighteen (18) months after the effective date of the Registration Statement (as defined in Rule 158(c) under the U.S. Securities Act), an earnings statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the U.S. Securities Act and Rule 158 under the U.S. Securities Act); and, to the extent required by law, to furnish to its shareholders after the end of each fiscal year an annual report (including a balance sheet and statements of income, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and after each of the first three fiscal quarters of each fiscal year (beginning with the first fiscal quarter after the effective date of the Registration Statement), consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail.

(j) To take promptly from time to time such actions as the Representative may reasonably request to qualify the Units for offering and sale under the securities or blue sky laws of such jurisdictions (domestic or foreign) as the Representative may designate and to continue such qualifications in effect, and to comply with such laws, for so long as required to permit the offer and sale of Units in such jurisdictions; provided that neither the Company nor any of its subsidiaries shall be obligated 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 or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

(k) That the Company will not, for a period of ninety (90) days from the date hereof, (the “Lock-Up Period”) without the prior written consent of the Underwriters, directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares, other than (i) the Company’s sale of the Shares and Warrants hereunder, (ii) the issuance by the Company of Common Shares or securities convertible into or exercisable for Common Shares to a strategic investor or in connection with the establishment of a joint venture or similar strategic relationship by the Company, in each case, on an arm’s-length basis with an unaffiliated third party, (iii) the issuance of restricted share rights or options to acquire Common Shares in a manner materially consistent with past practice pursuant to the Company Plans as in effect as of the date hereof and the issuance of Common Shares pursuant to the valid exercises, redemptions or conversion of restricted share rights, options or warrants outstanding on the date hereof; and (iv) the issuance of Common Shares, or other securities convertible into or exercisable for Common Shares, in connection with the acquisition of assets or other rights from an unaffiliated third party in an aggregate amount not to exceed (upon issue, conversion or exchange) 10% of the outstanding Common Shares of the Company after taking into account the Common Shares issued pursuant to the Offering, including exercise of the Over-Allotment Option, if applicable. The Company also agrees that during the Lock-Up Period, the Company will not file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the U.S. Securities Act for any transaction which registers, or offers for sale, Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares except where subject to an existing contractual obligation of the Company.

(l) To supply the Representative with copies of all written correspondence to and from, and all documents issued to and by, the Company and the Canadian Commissions and the SEC in connection with the qualification or registration of the Offered Securities under the Securities Act, the Canadian Securities Laws or the Registration Statement, or the Prospectuses or Amended Prospectuses, or any amendment or supplement thereto or document incorporated by reference therein.

(m) Prior to the Closing Date, and any Option Closing Date, to provide to the Representative, as soon as they have been prepared, copies of any unaudited interim consolidated financial statements of the Company for any periods subsequent to the periods covered by the financial statements appearing (including by way of incorporation by reference) in the Registration Statement and the Prospectuses and Amended Prospectuses.

(n) Not to directly or indirectly take or authorize any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Common Shares.

(o) Other than to add members to the underwriting syndicate, not to take any action prior to the Closing Date which would require the Prospectuses to be amended or supplemented pursuant to this Section 5.

(p) To apply the net proceeds from the sale of the Offered Securities as set forth in the Registration Statement, the General Disclosure Package, the Prospectuses and the Amended Prospectuses under the heading “Use of Proceeds.”

(q) To use its commercially reasonable best efforts to (i) list the Shares and Warrant Shares on the NYSE MKT and the Shares, Warrants and Warrant Shares on the TSX, subject to notice of issuance or similar listing requirements, and (ii) for a period of two years after the Closing Date, the Company shall not, unless approved by a special resolution of the shareholders of the Company, take any action which would be reasonably expected to result in the delisting or suspension of its Common Shares on or from the TSX or the NYSE MKT or on or from any securities exchange, market or trading or quotation facility on which its Common Shares are then listed or quoted and the Company shall use its commercially reasonable efforts to comply with the rules and regulations thereof; provided, that this covenant shall not prevent the Company from completing any transaction which would result in the Company ceasing to be “reporting issuer” so long as the holders of Common Shares receive securities of any entity which is listed on a stock exchange in Canada or the holders of the Common Shares have approved the transaction (or, in the case of a take-over bid, a sufficient number of Common Shares have been deposited to the bid in order to enable the bidder to utilize the “compulsory acquisition” provisions of the Business Corporations Act (British Columbia)) in accordance with the requirements of applicable corporate and securities laws and the policies of the TSX.

(r) The Company shall, for so long as any Warrants remain outstanding, file and bring effective, and maintain the effectiveness of, a registration statement (including, without limitation, the Registration Statement) under the U.S. Securities Act, that covers the issuance of the Warrant Shares upon exercise of the Warrants. The Company agrees to promptly notify the Warrant Agent, in writing, if such registration statement (including, without limitation, the Registration Statement) ceases to be effective under the U.S. Securities Act or can no longer be relied upon for the exercise of the Warrants. If and only if, at the time of exercise of a Warrant, a registration statement under the U.S. Securities Act that covers the issuance of the

Warrant Shares upon exercise of the Warrants is not effective, and if no commission or other remuneration has been paid or given directly or indirectly for soliciting such exercise, the holder of a Warrant may, in its sole discretion, exercise a Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the aggregate exercise price, elect instead to receive upon such exercise the “net number” of Common Shares determined according to the formula set forth in the terms of the Warrants.

(s) If any purchasers of Units resident in the United States (“U.S. Purchasers”) reasonably determine that the Company or any subsidiary thereof in which the Company owns more than 50% of such subsidiary’s aggregate voting power (“50% Subsidiary”) is likely a “passive foreign investment company” as defined under Section 1297 of the U.S. Internal Revenue Code (“PFIC”) in respect of any tax year, then, upon such U.S. Purchaser’s written request, the Company shall use its commercially reasonable efforts to make available to such purchasers for each such tax year (i) a “PFIC Annual Information Statement” as described in U.S. Treasury Regulation Section 1.1295-1(g) (or any successor Treasury Regulation) for the Company and any 50% Subsidiary which may be a PFIC and (ii) all information and documentation that a U.S. Purchaser is required to obtain for U.S. federal income tax purposes in making a qualifying electing fund (a “QEF”) election with respect to the Company and any 50% Subsidiary which may be a PFIC. The Company may elect to provide such information on its website.

(t) To use its commercially reasonable best efforts to do and perform all things required to be done or performed under this Agreement by the Company prior to the Closing Date, and any Option Closing Date, and to satisfy all conditions precedent to the delivery of the Firm Units and Additional Securities, if any.

The Company agrees to pay, or reimburse if paid by the Underwriters, upon consummation of the transactions contemplated hereby: (a) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and Warrants to the Underwriters and any stamp duties or other similar taxes payable in that connection; (b) the costs incident to the registration of the Shares and Warrants under the Canadian Securities Laws and the U.S. Securities Act; (c) the costs incident to the preparation, printing and distribution of the Registration Statement, the Base Prospectuses, the Form F-X, any Issuer Free Writing Prospectus, the General Disclosure Package, the Prospectuses, the Amended Prospectuses, any amendments, supplements and exhibits thereto or any document incorporated by reference therein and the costs of printing, reproducing and distributing any transaction document by mail or other means of communications; (d) the fees and expenses (including reasonable related fees and expenses of counsel to the Underwriters) incurred in connection with securing any required review by FINRA of the terms of the sale of the Shares and Warrants and any filings made with FINRA; (e) any applicable listing, quotation or other fees in connection with the listing or quotation of the Shares on the NYSE MKT and the TSX; (f) the fees and expenses (including reasonable related fees and expenses of counsel to the Underwriters) of qualifying the Shares and Warrants under the securities laws of the several jurisdictions as provided in Section 5(j); (g) the

cost of preparing and printing stock certificates, if any, for the Shares, and Warrant certificates; (h) all fees and expenses of the registrar and transfer agent of the Shares; (i) the reasonable fees, disbursements and expenses of counsel to the Underwriters in connection with the Offering (to a maximum of C$95,000, exclusive of taxes and disbursements, for Canadian counsel, and to a maximum of U.S.$125,000, exclusive of taxes and disbursements, for United States counsel, which for greater certainty shall cover any fees and expenses referred to in (d) and (f) above); and (j) all other costs and expenses incident to the Offering or the performance of the obligations of the Company under this Agreement (including, without limitation, the fees and expenses of the Company’s counsel and the Company’s independent accountants and the travel and other expenses incurred by the Company’s and Underwriters’ personnel in connection with any “road show” including, without limitation, any reasonable expenses advanced by the Underwriters on the Company’s behalf (which will be promptly reimbursed)).

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriter.

any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, any Registration Statement, the Prospectuses or the Amended Prospectuses, or in any amendment or supplement thereto or document incorporated by reference therein, (B) the omission or alleged omission to state in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, any Registration Statement or in any amendment thereto or document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein not misleading, (C) the omission or alleged omission to state in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, or the Prospectuses or Amended Prospectuses, or in any amendment or supplement thereto or document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading, or (D) any material breach of the representations and warranties of the Company contained herein or the failure of the Company to perform its obligations hereunder or pursuant to any law, and shall reimburse the Underwriter Indemnified Party promptly upon demand and presentation of documentation reasonably acceptable to the Company, for any legal fees or other expenses reasonably incurred by that Underwriter Indemnified Party in connection with investigating, or preparing to defend, or defending against, settling, compromising, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and 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, expense or liability arises out of or is based upon an untrue statement or alleged untrue statement in, or omission or alleged omission from any Registration Statement, Prospectus or Amended Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for use therein, which information the parties hereto agree is limited to the Underwriters’ Information (as defined in Section 18). This indemnity agreement is not exclusive and will be in addition to any liability which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Underwriter Indemnified Party.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company and its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the U.S. Securities Act or Section 20 of the U.S. Exchange Act (collectively, the “Company Indemnified Parties,” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the U.S. Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, any Registration Statement or the Prospectus, or in any amendment or

supplement thereto, (ii) the omission or alleged omission to state in any Registration Statement or in any amendment thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) the omission or alleged omission to state in any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the U.S. Securities Act, or the Prospectuses or Amended Prospectuses, or in any amendment or supplement thereto or document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they are made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for use therein, which information the parties hereto agree is limited to the Underwriters’ Information as defined in Section 18, and shall reimburse the Company Indemnified Party promptly upon demand for any legal fees or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against, settling, compromising or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. Notwithstanding the provisions of this Section 8(b), in no event shall any indemnity by any Underwriter under this Section 8(b) exceed the total discount and commission received by such Underwriter in connection with the Offering.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, investigation, proceeding or claim, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify such indemnifying party in writing of the commencement of that action, investigation, proceeding or claim; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such action, investigation, proceeding or claim shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action, investigation, proceeding or claim with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, investigation, proceeding or claim, except as provided herein, the indemnifying party shall not be liable to the indemnified party under Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action, investigation, proceeding or claim other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action, investigation, proceeding or claim and to participate in the defense of such action, investigation, proceeding or claim, but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 8(a) or by the Representative in the case of a claim for

indemnification under Section 8(b), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action, investigation, proceeding or claim and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action, investigation, proceeding or claim, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action, investigation, proceeding or claim on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action, investigation, proceeding or claim; provided, however, that the indemnifying party shall not, in connection with any one such action, investigation, proceeding or claim or separate but substantially similar or related actions, investigations, proceedings or claims in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by the Representative if the indemnified parties under this Section 8 consist of any Underwriter Indemnified Party or by the Company if the indemnified parties under this Section 8 consist of any Company Indemnified Parties. Subject to this Section 8(c), the amount payable by an indemnifying party under Section 8 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other reasonable expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action, investigation, proceeding or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or Section 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the Offering, or (ii) if the allocation provided by clause (i) of this Section 8(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 8(d) but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action,

investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to the Offering shall be deemed to be in the same proportion as the total net proceeds from the Offering under this Agreement (before deducting expenses) received by the Company bear to the total underwriting discount and commission received by the Underwriters in connection with the Offering, in each case as set forth in the table on the cover page of the Prospectuses and Amended Prospectuses. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the total discount and commission received by such Underwriter in connection with the Offering, less the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the U.S. Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

The obligations of the Underwriters hereunder may be terminated by the Representative, in its absolute discretion by written notice given to the Company prior to delivery of and payment for the Shares and Warrants if, prior to that time,

(a) any inquiry, action, suit, investigation or other proceeding (whether formal or informal) is instituted, announced or threatened or any order is issued by any governmental authority or otherwise in respect of the Company(other than an inquiry, investigation, proceeding or order based upon the activities or alleged activities of the Underwriters); or there is any change of law; or any order to cease trading in the securities of the Company is made by a governmental authority and that order is still in effect, which in the reasonable opinion of the Underwriter operates to prevent or restrict the trading in the Common Shares or the distribution of the Common Shares or which in the reasonable opinion of the Underwriter, acting in good faith, could be expected to have a material adverse effect on the market price or value of the Common Shares;

(b) there shall occur any material change or change in a material fact which, in the reasonable opinion of the Underwriter, would be expected to have a significant adverse effect on the market price or value of the Common Shares;

(c) there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence or any law or regulation which in the opinion of the Underwriter seriously adversely affects, or involves, or will seriously adversely affect, or involve, the financial markets or the business, operations or affairs of the Company and its subsidiaries taken as a whole;

(e) the Underwriter determines that any of the representations or warranties made by the Company in this Agreement is false or has become false in any material respect.

If this Agreement is terminated by any of the Underwriters pursuant to Section 9, there shall be no further liability on the part of such Underwriter, except in respect of any liability which may have arisen or may thereafter arise under Section 8. The right of the Underwriters or any of them to terminate their respective obligations under this Agreement is in addition to such other remedies as they may have in respect of any default, act or failure to act of the Company in respect of any of the matters contemplated by this Agreement. A notice of termination given by one Underwriter under this Section 9 shall not be binding upon the other Underwriters.

Notwithstanding anything to the contrary in this Agreement, if (a) this Agreement shall have been terminated pursuant to Section 9 other than by reason of the default of one or more Underwriters, (b) the Company shall fail to tender the Shares and Warrants for delivery to the Underwriters for any reason not permitted under this Agreement, (c) the Underwriters shall fail to purchase the Shares and Warrants for any reason permitted under this Agreement, or (d) the failure on the part of the Company to perform any agreement herein or to satisfy any condition or to comply with the provisions hereof, then, in addition to the payment of out-of-pocket expenses in accordance with Section 6 (but without duplication thereof), the Company shall reimburse the Underwriters for the fees and expenses of the Underwriters’ counsel and for such other accountable out-of-pocket expenses as shall have been reasonably incurred by them in connection with this Agreement and the proposed purchase of the Shares and Warrants, and upon demand the Company shall pay the full amount thereof to the Underwriters.

The Company acknowledges and agrees that (a) the purchase and sale of the Offered Securities pursuant to this Agreement, including the determination of the Purchase Price of the Offered Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters, on the other hand, (b) in connection with the Offering and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its shareholders, creditors, employees or any other party, (c) no Underwriter has assumed or will

assume an advisory or fiduciary responsibility in favour of the Company with respect to the Offering or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Corporation on other matters) and no Underwriter has any obligation to the Company with respect to the Offering except the obligations expressly set forth in this Agreement, and (d) the Underwriters and their respective affiliates are engaged in a broad range of transactions that may involve interests that differ from those of the Company.

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of any Offered Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

The respective indemnities, covenants, agreements, representations, warranties and other statements of the Company and the Underwriters, as set forth in this Agreement or made by them respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters, the Company or any person controlling any of them and shall survive delivery of and payment for the Units for a period until the later of: (i) two years following the Closing Date, and (ii) the latest date under Canadian Securities Laws and U.S. Securities Laws relevant to a purchaser of any Units (non-residents of Canada or the U.S. being deemed to be resident in the Province of British Columbia for such purposes) that a purchaser of Units may be entitled to commence an action or exercise a right of rescission, with respect to a misrepresentation contained in the Canadian Prospectus, Canadian Amended Prospectus, U.S. Prospectus, U.S. Amended Prospectus or, if applicable, any supplementary material, including without limitation any termination pursuant to Section 9, the indemnity and contribution and reimbursement agreements contained in Sections 8 and 10.
