WARRANTS 

Section 2.1 Issue of Warrants. The Warrants are hereby created and authorized to be countersigned and issued hereunder, upon and

receipt by the Warrant Agent of a written order of the Company to such effect. 
 Section 2.2 Warrant Certificates.
(a) On the terms and subject to the conditions of this Agreement and in accordance with the terms of the Plan and the Warrants, on the Effective Date or a date that is as soon as reasonably practicable after the Effective Date, the Company will

registered in the name of Cede & Co., as the nominee of The Depository Trust Company (the “Depository”). Each Global Warrant Certificate shall represent such number of the outstanding 2014 Warrants and the 2106 Warrants,
respectively, as specified therein, and each shall provide that it shall represent the aggregate amount of outstanding 2014 Warrants and the 2016 Warrants, respectively, from time to time endorsed thereon and that the aggregate amount of outstanding
2014 Warrants and the 2016 Warrants, respectively, represented thereby may from time to time be reduced or increased, as appropriate, in accordance with the terms of the Warrants. 

(b) Subject to this Agreement, each of the 2014 Warrants and the 2016 Warrants shall be issued in the form of the Global Warrant
Certificates, with the forms of election to exercise and of assignment printed on the reverse thereof, in substantially the form set forth in Exhibit A attached hereto. The Global Warrant Certificates may bear such appropriate
insertions, omissions, substitutions and other variations as are required or permitted by this Agreement and the Warrant, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be
required to comply with any law or with any rules made pursuant thereto or with any rules of any securities exchange or as may, consistently herewith, or, be determined by the Appropriate Officers executing such Global Warrant Certificates, as
evidenced by their execution of the Global Warrant Certificates, and all

of which shall be reasonably acceptable to the Warrant Agent. “Appropriate Officers” is defined as any of the Chairman of the Board of Directors of the Company, the Chief Executive
Officer of the Company, the President of the Company, any Senior Vice President of the Company or the Treasurer of the Company. 

(c) Notwithstanding anything in this Agreement to the contrary, the 2014 Warrants and the 2016 Warrants may be issued in certificated or
non-certificated form. Warrants issued to the Depository or its nominee may be in non-certificated form, in which case they shall be evidenced by a book entry position on the register of Warrant holders to be maintained by the Warrant Agent. For the
purpose of the administration of the Warrants, an electronic acknowledgement of a deposit request from the Depository by the Warrant Agent will be permitted in lieu of the delivery of a physical warrant certificate. 

Section 2.3 Registration and Countersignature. (a) Upon written order signed by an Appropriate Officer of the Company (a
“Written Order”), the Warrant Agent shall upon receipt of the Global Warrant Certificates duly executed on behalf of the Company, countersign one or more Global Warrant Certificates evidencing Warrants. Such written order of the
Company shall specifically state the number of Warrants that are to be issued as a Global Warrant Certificate. A Global Warrant Certificate shall be, and shall remain, subject to the provisions of this Agreement until such time as all of the
Warrants evidenced thereby shall have been duly exercised or shall have expired or been canceled in accordance with the terms thereof. 
 (b) No Global Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Global Warrant Certificate has been countersigned by the manual
signature of the Warrant Agent. Such signature by the Warrant Agent upon any Global Warrant Certificate executed by the Company shall be conclusive evidence that such Global Warrant Certificate so countersigned has been duly issued hereunder.

 (c) The countersignature of the Warrant Agent on a Global Warrant Certificate issued hereunder shall not be construed as a
representation or warranty by the Warrant Agent as to the validity of this Agreement, the Warrants or the Global Warrant Certificates (except the due certification thereof) and the Warrant Agent shall in no respect be liable or answerable for the
use made of the Warrants or the Global Warrant Certificates or any of them or of the consideration therefore except as otherwise specified herein. 
 Section 2.4 Signing of Certificates. Each Global Warrant Certificate shall be signed by any an Appropriate Officer of the Company.

stolen in exchange for and in place of and upon cancellation of such 

  
 3 








 
mutilated warrant certificate, or in lieu of and in substitution for such lost, destroyed or stolen warrant certificate, and the substituted warrant certificate shall be in a form approved by the
Warrant Agent and the Warrants evidenced thereby shall be entitled to the benefits hereof and shall rank pari passu with all other Warrants issued or to be issued hereunder. 
 (b) The applicant for the issue of a new warrant certificate pursuant to this Section 2.5 shall bear the reasonable cost of the issue thereof and in case of mutilation shall, as a condition precedent
to the issue thereof, deliver to the Warrant Agent the mutilated warrant certificate, and in case of loss, destruction or theft shall, as a condition precedent to the issue thereof, furnish to the Company and to the Warrant Agent such evidence of
ownership and of the loss, destruction or theft of the warrant certificate so lost, destroyed or stolen satisfactory to the Company and to the Warrant Agent, in their respective sole discretion, and such applicant may also be required to furnish an
indemnity and surety bond in amount and form satisfactory to the Company and the Warrant Agent, in their respective sole discretion, and shall pay the reasonable charges of the Company and the Warrant Agent in connection therewith. 

Section 2.6 Registration of Warrants. (a) Except as described below, registration of interests in and transfers of each of
the 2014 Warrants and the 2016 Warrants may be made through the securities registration system operated by the Depository and may be evidenced by one or more single fully registered Global Warrant Certificate(s) for an amount representing the
aggregate number of each of the 2014 Warrants and the 2106 Warrants, respectively, outstanding from time to time. 
 (b) The
Company may terminate the application of this Section 2.6 in its sole discretion, in which case all Warrants will be evidenced by one or more registered certificate(s). 
 (c) Transfers of beneficial ownership in any Warrant represented by a Global Warrant Certificate will be effected only with respect to the interest of a participant (or broker), through records maintained

Certificate may do so only through a participant/broker. 
 (d) The rights of beneficial owners shall be limited to those
established by applicable law and agreements between the Depository and the participants/brokers and between such participants/brokers and beneficial owners and must be exercised through a participant/broker in accordance with the rules and
procedures of the Depository. 
 (e) Subject to Subsection 2.6(h), neither the Company nor the Warrant Agent shall be under any
obligation to deliver to any participant/broker or beneficial owner, nor shall any participant or beneficial owner have any right to require the delivery of, a certificate or other instrument evidencing any interest in Warrants, except where
physical certificates evidencing ownership in securities are required to deal with Warrant exercises and restricted and/or legended securities. 
 (f) If any Warrant is represented by a Global Warrant Certificate and any of the following events occurs: 

  
 4 








 (i) the Depository or the Company has notified the Warrant Agent that (A) the
Depository is unwilling or unable to continue as Depository or (B) the Depository ceases to be a clearing agency in good standing under applicable laws and, in either case, the Company is unable to locate a qualified successor Depository within
90 days of delivery of such notice; or 
 (ii) the Company or the Depository is required by applicable law to take the action
contemplated in this Subsection 2.6(f); 
 then one or more definitive registered certificates shall be executed by the Company,
and countersigned and delivered by the Warrant Agent to the Depository in exchange for the Global Warrant Certificate(s) held by the Depository. 
 (g) Any registered certificates issued and exchanged pursuant to Section 2.6(f) shall be registered in such names and in such denominations as the Depository shall instruct the Warrant Agent,
provided that the aggregate number of Warrants represented by such registered certificates shall be equal to the aggregate number of Warrants represented by the Global Warrant Certificate(s) so exchanged. Upon exchange of a Global Warrant
Certificate for one or more certificates in definitive form, such Global Warrant Certificate shall be cancelled by the Warrant Agent. 
 (h) Notwithstanding anything herein or in the terms of the certificates to the contrary, neither the Company nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for:
(i) the records maintained by the Depository relating to any ownership interests or any other interests in the Warrants or the depository system maintained by the Depository, or payments made on account of any ownership interest or any other
interest of any person in any Warrant represented by any Global Warrant Certificate (other than the applicable Depository or its nominee); (ii) maintaining, supervising or reviewing any records of the Depository or any participant/broker
relating to any such interest; or (iii) any advice or representation made or given by the Depository or those contained herein that relate to the rules and regulations of the Depository or any action to be taken by the Depository on its own
direction or at the direction of any participant/broker. 
 Section 2.7 Transfer of Warrants. (a) A Warrant holder

 (b) Notwithstanding any provision to the contrary contained in this Agreement, the Company
will, on the advice of counsel, acting reasonably, be entitled, and may direct the Warrant Agent, and the Warrant Agent will, at the direction of the Company, acting reasonably, or otherwise on the advice of counsel, be entitled to refuse to
recognize and transfer, or enter the name of any transferee of any Warrant on the register if such transfer would constitute a violation of the securities laws of any jurisdiction.

Warrant holders in which shall be entered the names and addresses of the holders of the Warrants and of the number of Warrants held by each of them.

represented by him.

Agreement means, subject as hereinafter provided in this Section 5.11 and in Section 5.14, a resolution proposed at a meeting of Warrant holders duly convened for that purpose and held in accordance with the provisions of this Article V at

Warrant holders entitled to acquire not less than 66 2/3% of the aggregate number of shares which could be acquired pursuant to all of the then outstanding Warrants represented at the meeting and voted on the poll upon such resolution.

Warrant holders, whether signatories thereto or not, and each and every Warrant holder and the Warrant Agent (subject to the provisions for indemnity herein contained) shall be bound to give effect accordingly to every such resolution and instrument
in writing. In the case of an instrument in writing, the Warrant Agent shall give notice of the effect of the instrument in writing to all Warrant holders and the Company as soon as reasonably practicable. For greater certainty, a resolution or
extraordinary resolution amending the terms of this Agreement or of a Global Warrant Certificate shall not be binding upon the Company unless the Company agrees in writing to such amendment. 

Section 5.16 Holdings by Company Disregarded. In determining whether Warrant holders holding Warrants evidencing the entitlement
to acquire the required number of shares are present at a meeting of Warrant holders for the purpose of determining a quorum or have concurred in any consent, waiver, extraordinary resolution, Holders’ Request or other action under this
Agreement, Warrants owned legally or beneficially 

  
 13 









 
by the Company shall be disregarded. “Holders’ Request” means an instrument signed in one or more counterparts by Warrant holders entitled to acquire in the aggregate not less than
25% of the aggregate number of shares that could be acquired pursuant to all of the then outstanding Warrants under this Agreement, requesting the Warrant Agent to take some action or proceeding specified therein. 

ARTICLE VI 

COVENANTS 

Section 6.1 General Covenants. The Company covenants and agrees as follows: 

(a) All shares that are issued upon the exercise of the Warrants shall, upon issuance, be validly issued, not subject to any preemptive
rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), and be free from all taxes, liens, security interests, charges, and other encumbrances with respect to the issuance thereof, other than taxes
in respect of any transfer occurring contemporaneously with such issue. 
 (b) The Company shall at all times keep available and
free from preemptive rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), a sufficient number of shares to provide for the exercise of the rights represented by the Warrants. 

(c) Subject to the provision of the Warrants, the Company shall not, by amendment of its Articles through any reorganization, transfer of
assets, spin off, consolidation, merger, amalgamation dissolution, issue or sale of securities or any other action or inaction, seek to avoid the observance or performance of any of the terms of the Warrants. 

(d) The Company will duly and punctually perform and carry out all of the acts or things to be done by it as provided in this Agreement.

 Section 6.2 Warrant Agent’s Remuneration and Expenses. The Company covenants that it will pay to the Warrant
Agent from time to time reasonable remuneration for its services hereunder and will pay or reimburse the Warrant Agent upon its request for all reasonable expenses, disbursements and advances incurred or made by the Warrant Agent in the
administration or execution of the trusts hereby created (including the reasonable compensation and the disbursements of its counsel and all other advisers and assistants not regularly in its employ) both before any default hereunder and thereafter
until all duties of the Warrant Agent hereunder shall be finally and fully performed, except any such expense, disbursement or advance as may arise out of or result from the Warrant Agent’s gross negligence, willful misconduct or bad faith. Any
amount due under this Section 6.2 shall bear interest at a rate per annum equal to the current rate charged by the Warrant Agent from time to time from 30 days after the Warrant Agent shall have made a request for payment. This Section 6.2
shall survive the termination of this Agreement or the resignation or removal of the Warrant Agent. 

  
 14 









 Section 6.3 Performance of Covenants by Warrant Agent. If the Company shall fail to
perform any of its covenants contained in this Agreement, the Warrant Agent may notify the Warrant holders of such failure on the part of the Company or may itself perform any of the covenants capable of being performed by it but, subject to
Section 8.2, shall be under no obligation to perform said covenants or to notify the Warrant holders of such performance by it. All sums expended or advanced by the Warrant Agent in so doing shall be repayable as provided in Section 6.2.
No such performance, expenditure or advance by the Warrant Agent shall relieve the Company of any default hereunder or of its continuing obligations under the covenants herein contained. 

ARTICLE VII 
 SUPPLEMENTAL AGREEMENTS 
 Section 7.1 Provision for Supplementals for
Certain Purposes. From time to time the Company and the Warrant Agent may, without obtaining any approval of or consent from the Warrant holders, but subject to the provisions of this Agreement and they shall, when so directed in accordance with
the provisions hereof, execute and deliver by their proper officers, instruments supplemental hereto, which thereafter shall form part hereof, for any one or more or all of the following purposes: 

(a) setting forth any adjustments resulting from the application of the provisions of Article IV;

 CONCERNING THE WARRANT AGENT AND OTHER MATTERS

times in connection with this Agreement and in fulfillment of its obligations hereunder, comply with the applicable laws governing this Agreement, and be entitled to the rights and benefits provided under such laws. 

Section 8.2 Rights and Duties of Warrant Agent. (a) In the exercise of the rights and duties contained in this Agreement, the
Warrant Agent shall act in good faith and in the best interests of the Warrant holders and shall exercise that degree of care, diligence and skill that a reasonably prudent warrant agent would exercise in comparable circumstances. No provision in

 (b) Subject to Section 8.2(a), the Warrant Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the
Company or one or more Warrant holders shall furnish the Warrant Agent with security and indemnity satisfactory to it for any costs and expenses which may be incurred, but this provision shall not affect the power of the Warrant Agent to take such
action as it may consider proper, whether with or without any such security or indemnity. No provision of this Agreement shall require the Warrant Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of
any of its duties hereunder or in the exercise of its rights.

addition to the reports, certificates, opinions and other evidence required by this Agreement, the Company shall furnish to the Warrant Agent such additional evidence of compliance with any provision of this Agreement, and in such form, as may be
prescribed by law or as the Warrant Agent may reasonably require by written notice to the Company. 
 (b) In the absence of bad
faith on its part, the Warrant Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, resolutions or opinions furnished to the Warrant Agent and conforming to the
requirements of this Agreement. The Warrant Agent shall incur no liability or responsibility to the Company or to any holder for any action taken in reliance on any Global Warrant Certificate, certificate of shares, notice, resolution, waiver,
consent, order, certificate, or other paper, document or instrument (whether in its original or facsimile form) believed by it to be genuine and to have been signed, sent or presented by the proper party or parties, except as a result of its gross
negligence, bad faith or willful misconduct. 
 (c) The Warrant Agent may employ or retain such counsel, accountants, appraisers
or other experts or advisers as it may reasonably require for the purpose of discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, payable by the Company in accordance with
Section 6.2, without taxation of costs of any counsel, and shall not be responsible for any misconduct or negligence on the part of any such experts or advisers who have been appointed with due care by the


  
 16 









 
Warrant Agent. The Warrant Agent may act, or not act, and shall be protected in acting, or not acting, in good faith on the opinion or advice of or information obtained from any counsel,
accountant or other expert or advisor, whether retained or employed by the Company or the Warrant Agent, in relation to any matter arising in relation to this Agreement. 
 Section 8.4 Documents, Monies, Etc. Held by Warrant Agent. Any monies, securities, documents of title or other instruments that may at any time be held by the Warrant Agent subject to the trusts
hereof may be placed in the deposit vaults of the Warrant Agent or of any Canadian chartered bank listed in Schedule I of the Bank Act (Canada) or deposited for safekeeping with any such bank. Any monies so held pending the application or withdrawal
thereof under any provisions of this Agreement upon the direction of the Company, shall be or, with the consent of the Company, may be invested in securities issued or guaranteed by the Government of Canada or a province thereof, any Canadian
chartered bank listed in Schedule I of the Bank Act (Canada), or the Warrant Agent, provided that the securities shall not have a maturity date of more than sixty (60) days from the date of investment. Unless otherwise specifically provided

 Section 8.5 Actions by Warrant Agent to Protect Interest. Subject to the provisions of Agreement and applicable law, the Warrant Agent shall have power to institute and to maintain such actions and
proceedings as it may consider necessary or expedient to preserve, protect or enforce its interests and the interests of the registered holders.

Agreement. 
 Section 8.7 Protection of Warrant Agent. The Company and the Warrant Agent hereby agree as follows:

Warrant Agent assumes no responsibility for the correctness of any of the same except such as describe the Warrant Agent or action taken or to be taken by it; 
 (b) nothing contained in this Agreement shall impose any obligation on the Warrant Agent to see to or to require evidence of the registration or filing (or renewal thereof) of this Agreement or any
instrument ancillary or supplemental hereto; and 
 (c) the Warrant Agent shall not be bound to give notice to any person or
persons of the execution of this Agreement.

 Section 8.8 Indemnity. The Company agrees to indemnify the Warrant Agent, its
officers, directors, employee and agents, and save them harmless against any and all liabilities, claims, damages, including, but not limited to, judgments, costs and reasonable counsel fees, of whatever kind or nature, for anything done or omitted
by the Warrant Agent in connection with its acting as Warrant Agent hereunder, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith. Notwithstanding the foregoing, the Company shall not be responsible for
any settlement made without its written consent, which consent may not be unreasonably withheld. No provision in this Agreement shall be construed to relieve the Warrant Agent from liability for its own gross negligence, willful misconduct or bad
faith. This Section shall survive the termination of this Agreement or the resignation or removal of the Warrant Trustee. 

Section 8.9 Replacement of Warrant Agent; Successor by Merger. (a) The Warrant Agent may at any time resign as Warrant Agent
upon 60 days’ prior written notice to the Company. If the Warrant Agent shall become incapable of acting as Warrant Agent, the Company shall appoint a successor to such Warrant Agent. If the Company shall fail to make such appointment within a
period of 30 days after it has been notified in writing of such resignation or of such incapacity by the Warrant Agent or by the beneficial holder of the Warrants, then the beneficial holder of any Warrant or the Warrant Agent may apply, at the
expense of the Company, to any court of competent jurisdiction for the appointment of a successor to the Warrant Agent. Pending appointment of a successor to such Warrant Agent, either by the Company or by such a court, the duties of the Warrant
Agent shall be carried out by the Company. Such successor to the Warrant Agent need not be approved by the former Warrant Agent. After appointment the successor to the Warrant Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Warrant Agent without further act or deed; but the former Warrant Agent upon payment of all fees and expenses due it and its agents and counsel shall deliver and transfer to the successor to the
Warrant Agent any property at the time held by it hereunder and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Failure to give any notice provided for in this Section 8.9, however, or any defect
therein, shall not affect the legality or validity of the appointment of a successor to the Warrant Agent. 
 (b) Upon the
appointment of a successor Warrant Agent, the Company shall promptly notify the Warrant holders thereof in the manner provided for in this Agreement. 
 (c) Any corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Warrant Agent shall be a party, or any
corporation succeeding to the corporate trust business of the Warrant Agent shall be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for
appointment as a successor Warrant Agent under Section 8.9(a). 
 (d) Any Global Warrant Certificates countersigned but not
delivered by a predecessor Warrant Agent may be countersigned by the successor Warrant Agent in the name of the successor Warrant Agent. 

  
 18 









 Section 8.10 Conflict of Interest. (a) The Warrant Agent represents to the
Company that, to the best of its knowledge, at the time of execution and delivery hereof no material conflict of interest exists between its role as a Warrant Agent hereunder and its role in any other capacity and agrees that in the event of a
material conflict of interest arising hereafter it will, within 60 days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its rights and obligations hereunder to a successor Warrant Agent approved
by the Company and meeting the requirements set forth in Section 8.9(b). Notwithstanding the foregoing provisions of this Section 8.10(a), if any such material conflict of interest exists or hereafter shall exist, the validity and
enforceability of this Agreement shall not be affected in any manner whatsoever by reason thereof. 
 (b) The Warrant Agent, and
any stockholder, director, officer or employee of it, may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or
lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.

 Section 8.11 Anti-Money Laundering and Terrorist Financing. (a) The Company hereby represents to the Warrant
Agent that any account to be opened by, or interest to held by, the Warrant Agent in connection with this Agreement, for or to the credit of the Company is not intended to be used by or on behalf of any third party. 

(b) The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or
for any other reason whatsoever, the Warrant Agent, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further,
should the Warrant Agent, in its sole judgment, determine at any time that its acting under this Agreement has resulted in it being in non-compliance with any applicable anti-money laundering or antiterrorist legislation, regulation or guideline,
then, notwithstanding the provisions of Section 8.9, the Warrant Agent shall have the right to resign on 10 days’ written notice to the Company, provided (i) that the Warrant Agent’s written notice shall describe the
circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Warrant Agent’s satisfaction within such 10 day period, then such resignation shall not be effective. 

Section 8.12 Privacy. The parties acknowledge that federal and/or provincial legislation that addresses the protection of
individuals’ personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, neither party shall take or direct any action that
would contravene, or cause the other to contravene, applicable Privacy Laws. The Company shall, prior to transferring or causing to be transferred personal information to the Warrant Agent, obtain and retain required consents of the relevant
individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Warrant
Agent shall use commercially 

  
 19 









 
reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Warrant Agent agrees: (a) to have a designated chief privacy officer; (b) to
maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry; (c) to use personal information solely for the purposes of providing its services under or ancillary to this
Agreement and not to use it for any other purpose except with the consent of or direction from the corporation or the individual involved; (d) not to sell or otherwise improperly disclose personal information to any third party; and (e) to
employ administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized access, use or modification.

the same upon the terms and conditions herein set forth and, among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for and pay to the Company all moneys received by the Warrant Agent
upon the exercise of the Warrants. 
 Section 8.14 Warrant Agent Not to be Appointed Receiver. The Warrant Agent and any
person related to the Warrant Agent shall not be appointed a receiver, a receiver and manager or liquidator of all or any part of the assets or undertaking of the Company.

consideration to the extent that it is not cash) over the Exercise Price or (ii) an amount equal to fifty percent of the fair market value of this Warrant at the time of the consummation of the Change of Control Transaction(such fair market
value to be determined in accordance with clauses (v) through (z) of this definition, provided that the aggregate fair market value of equity pursuant to clause (v) above shall be deemed to give rise to a value per Share equal
to the Exercise Price), or (C) in the case of Section 12, the fair market value of the Shares. For the avoidance of doubt, the Appraiser shall not, in considering the factors enumerated in clause (B) of the preceding sentence, take
into account any discounts for minority status or if the holder of the Warrant Shares, Shares or Warrants controls the Company, any premium that such holder of the Warrant Shares, Shares or Warrants would receive in an arms-length transfer of such

principal office of the Company (or to such other place as the Company shall notify the Holder hereof in writing) (i) a written notice of exercise in the form of Exhibit A (an “Exercise Notice”), and
(ii) either (A) a statement by the Holder of its election to exercise this Warrant on a cashless basis as described in Section 5(b) or (B) payment of an amount equal to the Exercise Price multiplied by the number of Warrant Shares
being purchased by the Holder upon exercise of the Warrant in immediately available funds (the “Aggregate Exercise Price”). The Holder shall be deemed to have become a holder of record of such Warrant Shares as of the Exercise Date.

 (b) Beginning on the date that is six months prior to the expiration of this Warrant, in lieu of paying the
Exercise Price in cash upon exercise of this Warrant, the Holder may elect to forfeit that number of Warrant Shares which have a Fair Market Value equal to the Aggregate Exercise Price of the Warrant Shares being purchased (“Net

	        A =	  	the Fair Market Value of one (1) Warrant Share on the Exercise Date; and
		
	        B =	  	the Exercise Price.

 (c) As a condition to the exercise of this Warrant, prior to any Shares being issued,
unless the Holder is already a party to the Shareholders’ Agreement at the time of the proposed exercise, the Holder shall execute and deliver to the Company a joinder agreement to the Shareholders’ Agreement; provided however, that the
foregoing restriction shall cease to apply after a Qualified Initial Public Offering. 
 (d) No Shares will be
issued upon exercise of this Warrant unless the Shares are issued through a depository and beneficial ownership in such Share is to be held through a bank or broker that is already considered a holder of the Shares for purposes of determining the
number of holders of record (as such concept is understood for purposes of Section 12(g) of the 1934 Act), as determined by the Company, in its sole discretion, acting reasonably; provided, however, that the foregoing restriction
shall cease to apply after a Public Offering. 
 6. Exercise In the Event of a Change of Control Transaction. Upon the
consummation of a Change of Control Transaction, this Warrant shall be automatically cancelled and deemed surrendered to the Company and the Company shall pay in exchange therefor immediately available funds in an amount equal to the Fair Market
Value of this Warrant. 
 7. New Warrant If this Warrant is exercised in part, then the Company shall issue, or cause to
have issued, to the Holder a new warrant with identical terms to this Warrant, but with the amount of Shares subject to such new warrant being reduced by the number of Shares theretofore issued pursuant to all exercises of the purchase rights

stamp or similar issue or transfer taxes with respect to the issue or delivery of the Warrant Shares. However, the Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Shares in a name

 -6-









 9. Reservation and Registration of Shares. The Company covenants and agrees to the
Holder and the Warrant Agent as follows: 
 (a) All Warrant Shares that are issued upon the exercise of this
Warrant shall, upon issuance, be validly issued, not subject to any preemptive rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), and be free from all taxes, liens, security interests,
charges, and other encumbrances with respect to the issuance thereof, other than taxes in respect of any transfer occurring contemporaneously with such issue. 
 (b) The Company shall at all times keep available and free from preemptive rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), a sufficient number
of Shares to provide for the exercise of the rights represented by this Warrant. 
 (c) The Company shall not, by
amendment of its Articles through any reorganization, transfer of assets, spin off, consolidation, merger, amalgamation dissolution, issue or sale of securities or any other action or inaction, seek to avoid the observance or performance of any of
the terms of this Warrant. 
 10. Adjustment of Exercise Price and Number of Shares. The number of and kind of securities
purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows: 
 (a) Subdivisions, Combinations and Other Issuances. If the Company shall at any time prior to the expiration of this Warrant subdivide the Shares, by split-up or otherwise, or combine the Shares,
or issue additional Shares as a dividend, the number of Warrant Shares shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Any adjustment under this
Section 10(a) shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such
dividend. If the number of Warrant Shares is adjusted as provided for in this Section 10(a), the Exercise Price shall be adjusted by multiplying the Exercise Price immediately prior to such adjustment by a fraction, the numerator of which shall be
the number of Warrant Shares immediately prior to such adjustment, and the denominator of which shall be the number of Warrant Shares immediately after such adjustment. 

(b) Reclassification, Reorganization and Consolidation. Except as provided in Section 6, in case of any
reclassification, merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the Company immediately after such merger in the same relative percentages), amalgamation, consolidation,
capital reorganization, or change in the capital stock of the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 10(a)), then the Company shall make appropriate provision so that the Holder
shall have the right at any time thereafter and prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant in whole for all Warrant Shares, the kind and amount of shares of stock and
other securities 

  
 -7-









 
and property receivable in connection with such reclassification, merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the
Company immediately after such merger in the same relative percentages), amalgamation, consolidation, reorganization or change by a holder of the same number of Shares as the number of Warrant Shares immediately prior to such reclassification,
merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the Company immediately after such merger in the same relative percentages), amalgamation, consolidation, capital reorganization,
or change. In any such case the Board of Directors of the Company shall determine in good faith other appropriate provisions with respect to the rights and interests of the Holder so that the provisions hereof shall thereafter be applicable with
respect to any securities and property deliverable upon exercise hereof. 
 (c) Extraordinary
Distributions. If the Company shall at any time prior to the expiration of this Warrant (i) make distributions (by dividend or otherwise) of any assets to all of the holders of the Shares (other than to those holding restricted Shares)
(including but not limited to cash, securities, or warrants to purchase securities (including but not limited to the Shares)), other than a regular dividend following a Public Offering, (ii) grant rights to purchase securities to all of the
holders of the Shares (other than to those holding restricted Shares), (iii) offer securities of the Company to all of the holders of the Shares (other than to those holding restricted Shares), regardless of whether or not all such holders
purchased such securities, or (iv) make any offer to purchase all of the Shares (other than to those holding restricted Shares), in the case of clauses (ii) and (iii) at a price below Fair Market Value, and in the case of clause
(iv) at a price above Fair Market Value, and in each case of clauses (i), (ii), (iii) and (iv) other than as described in Section 10(a) or Section 10(b) (any such non-excluded event being referred to herein as an
“Extraordinary Distribution”), then the Exercise Price shall be decreased, effective immediately after (x) the record or other distribution date of such Extraordinary Distribution, by the amount of cash and/or Fair Market Value
of any securities or assets paid or distributed on each Share in respect of such Extraordinary Distribution, (y) in the case of clauses (ii) and (iii), on the date of the issuance of such securities by the amount attributable to each
outstanding Share of the excess of the amount of proceeds such securities would have produced had they been sold at Fair Market Value over the actual amount of proceeds or (z) in the case of clause (iv), on the date of the consummation of such
offer to purchase the Shares by the amount attributable to each outstanding Share of the excess of the consideration paid for the Shares over the Fair Market Value of the Shares. 

(d) Notice of Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable
upon exercise of this Warrant, or in the Exercise Price, the Company shall promptly notify the Holder and the Warrant Agent of such event and of the number of Shares or other securities or property thereafter purchasable upon exercise of this
Warrant and, if applicable, the adjusted Exercise Price. 

  
 -8-









 (e) Other Notices. In case at any time or from time to time the
Company shall enter into any agreement regarding a transaction described in Section 6 or Section 10 then the Company shall promptly send the Holder and the Warrant Agent a notice stating, as applicable (A) the date on which a record is to be
taken for the purpose of such dividend, distribution or granting of rights or warrants or, if a record is not to be taken, the date as of which the holders of Shares of record to be entitled to such dividend, distribution or granting of rights or
warrants are to be determined, or (B) the date on which such transaction is expected to become effective and the date as of which it is expected that holders of Shares of record shall be entitled to exchange their Shares for shares of stock or
other securities or property or cash deliverable upon such transaction. 
 (f) Par Value of Shares. In no
event shall the Exercise Price be adjusted below zero. 
 11. Determination of Fair Market Value. 

(a) Determination. In the case of clauses (A) and (C) of the definition of Fair Market Value,
determinations of Fair Market Value shall be made by the Board of Directors of the Company acting in good faith and after considering the advice of independent financial experts. In the case of clause (B) of the definition of Fair Market Value,
determinations of Fair Market Value shall be made by mutual agreement between (i) Persons holding more than 50.1% of the Warrants and (ii) the Company; provided, that in determining whether the requisite number of Warrant holders
have agreed to such Fair Market Value, Warrants held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded; provided
further, that if such agreement is not reached within twenty days (in the case of a determination in connection with a Change of Control Transaction) or sixty days (in all other cases) following a request by the Holders for a determination of
Fair Market Value then the parties shall submit such dispute (any such dispute, a “Fair Market Value Dispute”) to the Appraiser for resolution by it within thirty days thereafter; provided, further, that the Exercise
Period shall be tolled until ten business days after such Fair Market Value Dispute has been finally determined by the Appraiser and notice of such determination has been provided to the Holders; provided, further, that in connection
with a Change of Control Transaction the time periods set forth on Exhibit C shall be tolled until ten business days after such Fair Market Value Dispute has been finally determined by the Appraiser and notice of such determination has been
provided to the Holders. Notwithstanding anything contained herein , in each case of clauses (A), (B) and (C) of the definition of Fair Market Value following a Public Offering and if the Shares are then Marketable Securities, the fair
market value of the Shares shall be deemed to equal the average of the Volume Weighted Average Prices of the Shares during a period of twenty consecutive Trading Days ending on the Exercise Date or the date the Change of Control Transaction is first
announced, as applicable. At the time of submission of the Fair Market Value Dispute to the Appraiser, the parties shall each submit to the Appraiser and to 

  
 -9-









 
each other a memorandum explaining its respective position on the Fair Market Value Dispute in such detail as they may deem appropriate. The Appraiser, as soon as reasonably practicable after
submission, shall consult with the parties jointly and decide the Fair Market Value Dispute. Each of the parties shall cooperate with the Appraiser and provide it with such access and information as such firm may require in order to render its
determination. The Appraiser shall render such decision and report to the parties in writing specifying the reasons for its decision in reasonable detail, not later than thirty days following the date the Fair Market Value Dispute was submitted to
it. The determination of the Appraiser shall be final, binding and conclusive, including through the expiration of this Warrant, and shall not be subject to appeal and shall be deemed to have been accepted by the parties; provided, that if
such determination is rendered in connection with a Change of Control Transaction, any determination of Fair Market Value delivered by the Appraiser in connection therewith shall not be binding upon the parties if such Change of Control Transaction
is not consummated. 
 (b) Appraiser. Within five business days after the twenty day or sixty day period
(as applicable) described in Section 11(a) the Company shall give each of the Warrant holders and the Warrant Agent notice that the Appraiser will be appointed and the Appraiser shall be appointed by the Company within five business days after such
notice is provided subject to the consent of Persons holding more than 50.1% of the Warrants (provided, that in determining whether the requisite number of Warrant holders have agreed to the appointment of the Appraiser, Warrants held by the
Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded), which consent shall not be unreasonably withheld and which consent shall be presumed if
the Company is not informed in writing to the contrary by Persons holding more than 50.1% of the Warrants (provided, that in determining whether the requisite number of Warrant holders have agreed to the appointment of the Appraiser, Warrants
held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded) prior to the appointment of the Appraiser; provided, that in
determining whether the requisite number of Warrant holders have consented to the Appraiser, Warrants held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Company, shall be disregarded. The costs and expenses associated with the Appraiser shall be borne by the Company. 
 12. No
Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional Shares, or scrip representing fractional Shares, the Company shall make a
cash payment therefor on the basis of the Fair Market Value per Share then in effect. 

  
 -10-









 13. Transferability. This Warrant and the Warrant Shares may not be offered, sold,
transferred, pledged or otherwise disposed of, in whole or in part, to any Person other than in accordance with applicable federal and state securities laws, and, in respect of the Warrant Shares only, also in accordance with the Articles and the
Shareholders’ Agreement. In addition, no Holder shall Transfer any Warrants to any other Person if such Transfer would, if effected, result in the Company having more than 290 holders of record (as such concept is understood for purposes of
Section 12(g) of the 1934 Act), as determined by the Company, in its sole discretion, acting reasonably; provided, however, that the foregoing restriction shall cease to apply after a Public Offering. For greater certainty, any
Transfer that violates the foregoing shall be deemed to be null and void ab initio and of no force and effect, and the Company shall not in any way give effect to or be required to recognize any such impermissible Transfer. 

14. Successors and Assigns. This Warrant shall be binding upon and inure to the benefit of the Holder and its permitted assigns,
and shall be binding upon any entity succeeding to the Company by consolidation, merger or acquisition of all or substantially all of the Company’s assets. This Warrant and all rights hereunder are transferable by the Holder only pursuant to
Section 13. 
 15. Rights of Shareholders. The Holder shall not be entitled, as a Warrant holder, to vote or receive
dividends or be deemed the holder of the Shares or any other securities of the Company which may at any time be issuable on the exercise hereof for any purpose, nor, subject to Section 227 of the British Columbia Business Corporations Act,
provided the Holder is a Person whom the Court considers to be an appropriate Person to make an application under that section, shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of
the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the
Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. 
 16. Expiration of
Warrant. Subject to the provisions of Section 6, this Warrant shall expire and shall no longer be exercisable at 5:00 p.m., Eastern time, on June 9, 2014.

being purchased by the Holder upon exercise of the Warrant in immediately available funds (the “Aggregate Exercise Price”). The Holder shall be deemed to have become a holder of record of such Warrant Shares as of the Exercise Date.

 (b) Beginning on the date that is six months prior to the expiration of this Warrant, in lieu of paying the
Exercise Price in cash upon exercise of this Warrant, the Holder may elect to forfeit that number of Warrant Shares which have a Fair Market Value equal to the Aggregate Exercise Price of the Warrant Shares being purchased (“Net

 exercising its purchase rights under this Warrant;

		
	        A =	  	the Fair Market Value of one (1) Warrant Share on the Exercise Date; and
		
	        B =	  	the Exercise Price.

  
  
  

(c) As a condition to the exercise of this Warrant, prior to any Shares being issued, unless the Holder is already a party
to the Shareholders’ Agreement at the time of the proposed exercise, the Holder shall execute and deliver to the Company a joinder agreement to the Shareholders’ Agreement; provided however, that the foregoing restriction shall cease to
apply after a Qualified Initial Public Offering. 
 (d) No Shares will be issued upon exercise of this Warrant
unless the Shares are issued through a depository and beneficial ownership in such Share is to be held through a bank or broker that is already considered a holder of the Shares for purposes of determining the number of holders of record (as such
concept is understood for purposes of Section 12(g) of the 1934 Act), as determined by the Company, in its sole discretion, acting reasonably; provided, however, that the foregoing restriction shall cease to apply after a Public
Offering. 
 6. Exercise In the Event of a Change of Control Transaction. Upon the consummation of a Change of Control
Transaction, this Warrant shall be automatically cancelled and deemed surrendered to the Company and the Company shall pay in exchange therefor immediately available funds in an amount equal to the Fair Market Value of this Warrant. 

7. New Warrant If this Warrant is exercised in part, then the Company shall issue, or cause to have issued, to the Holder a new
warrant with identical terms to this Warrant, but with the amount of Shares subject to such new warrant being reduced by the number of Shares theretofore issued pursuant to all exercises of the purchase rights evidenced by this Warrant or any
replacement thereof. 
 8. Payment of Taxes. The Company shall pay any documentary, stamp or similar issue or transfer
taxes with respect to the issue or delivery of the Warrant Shares. However, the Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Shares in a name other than the Holder’s name.
Nothing herein shall preclude any tax withholding required by law or regulation. 

  
 -6-









 9. Reservation and Registration of Shares. The Company covenants and agrees to the
Holder and the Warrant Agent as follows: 
 (a) All Warrant Shares that are issued upon the exercise of this
Warrant shall, upon issuance, be validly issued, not subject to any preemptive rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), and be free from all taxes, liens, security interests,
charges, and other encumbrances with respect to the issuance thereof, other than taxes in respect of any transfer occurring contemporaneously with such issue. 
 (b) The Company shall at all times keep available and free from preemptive rights (other than those granted in favor of the shareholders of the Company as set forth in the Articles), a sufficient number
of Shares to provide for the exercise of the rights represented by this Warrant. 
 (c) The Company shall not, by
amendment of its Articles through any reorganization, transfer of assets, spin off, consolidation, merger, amalgamation dissolution, issue or sale of securities or any other action or inaction, seek to avoid the observance or performance of any of
the terms of this Warrant. 
 10. Adjustment of Exercise Price and Number of Shares. The number of and kind of securities
purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows: 
 (a) Subdivisions, Combinations and Other Issuances. If the Company shall at any time prior to the expiration of this Warrant subdivide the Shares, by split-up or otherwise, or combine the Shares,
or issue additional Shares as a dividend, the number of Warrant Shares shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Any adjustment under this
Section 10 (a) shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such
dividend. If the number of Warrant Shares is adjusted as provided for in this Section 10 (a), the Exercise Price shall be adjusted by multiplying the Exercise Price immediately prior to such adjustment by a fraction, the numerator of which shall be
the number of Warrant Shares immediately prior to such adjustment, and the denominator of which shall be the number of Warrant Shares immediately after such adjustment. 

(b) Reclassification, Reorganization and Consolidation. Except as provided in Section 6, in case of any
reclassification, merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the Company immediately after such merger in the same relative percentages), amalgamation, consolidation,
capital reorganization, or change in the capital stock of the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 10 (a)), then the Company shall make appropriate provision so that the Holder
shall have the right at any time thereafter and prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant in whole for all Warrant Shares, the kind and amount of shares of stock and
other securities 

  
 -7-









 
and property receivable in connection with such reclassification, merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the
Company immediately after such merger in the same relative percentages), amalgamation, consolidation, reorganization or change by a holder of the same number of Shares as the number of Warrant Shares immediately prior to such reclassification,
merger (in which the beneficial owners of the Company immediately prior to such merger remain the beneficial owners of the Company immediately after such merger in the same relative percentages), amalgamation, consolidation, capital reorganization,
or change. In any such case the Board of Directors of the Company shall determine in good faith other appropriate provisions with respect to the rights and interests of the Holder so that the provisions hereof shall thereafter be applicable with
respect to any securities and property deliverable upon exercise hereof. 
 (c) Extraordinary
Distributions. If the Company shall at any time prior to the expiration of this Warrant (i) make distributions (by dividend or otherwise) of any assets to all of the holders of the Shares (other than to those holding restricted Shares)
(including but not limited to cash, securities, or warrants to purchase securities (including but not limited to the Shares)), other than a regular dividend following a Public Offering, (ii) grant rights to purchase securities to all of the
holders of the Shares (other than to those holding restricted Shares), (iii) offer securities of the Company to all of the holders of the Shares (other than to those holding restricted Shares), regardless of whether or not all such holders
purchased such securities, or (iv) make any offer to purchase all of the Shares (other than to those holding restricted Shares), in the case of clauses (ii) and (iii) at a price below Fair Market Value, and in the case of clause
(iv) at a price above Fair Market Value, and in each case of clauses (i), (ii), (iii) and (iv) other than as described in Section 10 (a) or Section 10 (b) (any such non-excluded event being referred to herein as an
“Extraordinary Distribution”), then the Exercise Price shall be decreased, effective immediately after (x) the record or other distribution date of such Extraordinary Distribution, by the amount of cash and/or Fair Market Value
of any securities or assets paid or distributed on each Share in respect of such Extraordinary Distribution, (y) in the case of clauses (ii) and (iii), on the date of the issuance of such securities by the amount attributable to each
outstanding Share of the excess of the amount of proceeds such securities would have produced had they been sold at Fair Market Value over the actual amount of proceeds or (z) in the case of clause (iv), on the date of the consummation of such
offer to purchase the Shares by the amount attributable to each outstanding Share of the excess of the consideration paid for the Shares over the Fair Market Value of the Shares. 

(d) Notice of Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable
upon exercise of this Warrant, or in the Exercise Price, the Company shall promptly notify the Holder and the Warrant Agent of such event and of the number of Shares or other securities or property thereafter purchasable upon exercise of this
Warrant and, if applicable, the adjusted Exercise Price. 

  
 -8-









 (e) Other Notices. In case at any time or from time to time the
Company shall enter into any agreement regarding a transaction described in Section 6 or Section 10 then the Company shall promptly send the Holder and the Warrant Agent a notice stating, as applicable (A) the date on which a record is to be
taken for the purpose of such dividend, distribution or granting of rights or warrants or, if a record is not to be taken, the date as of which the holders of Shares of record to be entitled to such dividend, distribution or granting of rights or
warrants are to be determined, or (B) the date on which such transaction is expected to become effective and the date as of which it is expected that holders of Shares of record shall be entitled to exchange their Shares for shares of stock or
other securities or property or cash deliverable upon such transaction. 
 (f) Par Value of Shares. In no
event shall the Exercise Price be adjusted below zero. 
 11. Determination of Fair Market Value. 

(a) Determination. In the case of clauses (A) and (C) of the definition of Fair Market Value,
determinations of Fair Market Value shall be made by the Board of Directors of the Company acting in good faith and after considering the advice of independent financial experts. In the case of clause (B) of the definition of Fair Market Value,
determinations of Fair Market Value shall be made by mutual agreement between (i) Persons holding more than 50.1% of the Warrants and (ii) the Company; provided, that in determining whether the requisite number of Warrant holders
have agreed to such Fair Market Value, Warrants held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded; provided further,
that if such agreement is not reached within twenty days (in the case of a determination in connection with a Change of Control Transaction) or sixty days (in all other cases) following a request by the Holders for a determination of Fair Market
Value then the parties shall submit such dispute (any such dispute, a “Fair Market Value Dispute”) to the Appraiser for resolution by it within thirty days thereafter; provided, further, that the Exercise Period shall
be tolled until ten business days after such Fair Market Value Dispute has been finally determined by the Appraiser and notice of such determination has been provided to the Holders; provided, further, that in connection with a Change
of Control Transaction the time periods set forth on Exhibit C shall be tolled until ten business days after such Fair Market Value Dispute has been finally determined by the Appraiser and notice of such determination has been provided to the
Holders. Notwithstanding anything contained herein , in each case of clauses (A), (B) and (C) of the definition of Fair Market Value following a Public Offering and if the Shares are then Marketable Securities, the fair market value of the
Shares shall be deemed to equal the average of the Volume Weighted Average Prices of the Shares during a period of twenty consecutive Trading Days ending on the Exercise Date or the date the Change of Control Transaction is first announced, as
applicable. At the time of submission of the Fair Market Value Dispute to the Appraiser, the parties shall each submit to the Appraiser and to 

  
 -9-









 
each other a memorandum explaining its respective position on the Fair Market Value Dispute in such detail as they may deem appropriate. The Appraiser, as soon as reasonably practicable after
submission, shall consult with the parties jointly and decide the Fair Market Value Dispute. Each of the parties shall cooperate with the Appraiser and provide it with such access and information as such firm may require in order to render its
determination. The Appraiser shall render such decision and report to the parties in writing specifying the reasons for its decision in reasonable detail, not later than thirty days following the date the Fair Market Value Dispute was submitted to
it. The determination of the Appraiser shall be final, binding and conclusive, including through the expiration of this Warrant, and shall not be subject to appeal and shall be deemed to have been accepted by the parties; provided, that if
such determination is rendered in connection with a Change of Control Transaction, any determination of Fair Market Value delivered by the Appraiser in connection therewith shall not be binding upon the parties if such Change of Control Transaction
is not consummated. 
 (b) Appraiser. Within five business days after the twenty day or sixty day period
(as applicable) described in Section 11 (a) the Company shall give each of the Warrant holders and the Warrant Agent notice that the Appraiser will be appointed and the Appraiser shall be appointed by the Company within five business days after such
notice is provided subject to the consent of Persons holding more than 50.1% of the Warrants (provided, that in determining whether the requisite number of Warrant holders have agreed to the appointment of the Appraiser, Warrants held by the
Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded), which consent shall not be unreasonably withheld and which consent shall be presumed if
the Company is not informed in writing to the contrary by Persons holding more than 50.1% of the Warrants (provided, that in determining whether the requisite number of Warrant holders have agreed to the appointment of the Appraiser, Warrants
held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be disregarded) prior to the appointment of the Appraiser; provided, that in
determining whether the requisite number of Warrant holders have consented to the Appraiser, Warrants held by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Company, shall be disregarded. The costs and expenses associated with the Appraiser shall be borne by the Company. 
 12. No
Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional Shares, or scrip representing fractional Shares, the Company shall make a
cash payment therefor on the basis of the Fair Market Value per Share then in effect. 

  
 -10-









 13. Transferability. This Warrant and the Warrant Shares may not be offered, sold,
transferred, pledged or otherwise disposed of, in whole or in part, to any Person other than in accordance with applicable federal and state securities laws, and, in respect of the Warrant Shares only, also in accordance with the Articles and the
Shareholders’ Agreement. In addition, no Holder shall Transfer any Warrants to any other Person if such Transfer would, if effected, result in the Company having more than 290 holders of record (as such concept is understood for purposes of
Section 12(g) of the 1934 Act), as determined by the Company, in its sole discretion, acting reasonably; provided, however, that the foregoing restriction shall cease to apply after a Public Offering. For greater certainty, any
Transfer that violates the foregoing shall be deemed to be null and void ab initio and of no force and effect, and the Company shall not in any way give effect to or be required to recognize any such impermissible Transfer. 

14. Successors and Assigns. This Warrant shall be binding upon and inure to the benefit of the Holder and its permitted assigns,
and shall be binding upon any entity succeeding to the Company by consolidation, merger or acquisition of all or substantially all of the Company’s assets. This Warrant and all rights hereunder are transferable by the Holder only pursuant to
Section 13. 
 15. Rights of Shareholders. The Holder shall not be entitled, as a Warrant holder, to vote or receive
dividends or be deemed the holder of the Shares or any other securities of the Company which may at any time be issuable on the exercise hereof for any purpose, nor, subject to Section 227 of the British Columbia Business Corporations Act,
provided the Holder is a Person whom the Court considers to be an appropriate Person to make an application under that section, shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of
the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the
Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. 
 16. Expiration of
Warrant. Subject to the provisions of Section 6, this Warrant shall expire and shall no longer be exercisable at 5:00 p.m., Eastern time, on June 9, 2016.
