(a)Registration Period. The Company’s registration obligations set forth in this Section 2 including its obligations to file Registration Statements, obtain effectiveness of Registration Statements, and maintain the continuous effectiveness of any Registration Statement that has been declared effective shall begin on the date hereof and continue until all the Registrable Securities have been sold or may be sold without any restrictions pursuant to Rule 144, as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and reasonably acceptable to the Company’s transfer agent (the “Registration Period”).

(b)Mandatory Registration. Subject to the terms and conditions of this Agreement, the Company shall (i) on or prior to the Filing Deadline, prepare and file (A) with the Ontario Securities Commission a Canadian Prospectus Supplement allowing for, amongst other things, secondary market sales of Common Shares in the United States, and (B) prepare and file with the SEC the Canadian Prospectus Supplement pursuant to General Instruction II.L of Form F-10, or, if Form F-10 is not available to the Company, prepare and file a Registration Statement on Form F-3 or such other form as may be available to the Company, in either case relating to and providing for the resale of the Registrable Securities on a continuous basis pursuant to Rule 415, if applicable, and cause the SEC to declare such Registration Statement effective, and (ii) on or prior to the 10th Business Day following receipt of each written notice by the Investor (a “Demand Notice”) delivered pursuant to the terms hereof, prepare and file an additional Registration Statement covering the resale by the Investor of Registrable Securities not covered by the initial Registration Statement. Each Registration Statement prepared pursuant hereto shall register for resale at least the number of Common Shares such that the pro forma Common Shares then registered in a Registration Statement and unissued will be equal to the Required Registration Amount as of date the Registration Statement is initially filed with the SEC. In addition, if at any time, clause (ii) of the Required Registration Amount exceeds 250% of the number of Common Shares then registered in a Registration Statement and unissued, then the Company shall file as soon as reasonably practicable, but in any case prior to the applicable Filing Deadline, an additional Registration Statement covering the resale by the Holders of a number of Common Shares such that the pro forma Common Shares then registered in a Registration Statement and unissued will be equal to not less than the Required Registration Amount. Each Canadian Prospectus Supplement and Registration Statement shall contain “Selling Stockholders” and “Plan of Distribution” sections; provided, however, that the Company’s obligations hereunder are contingent upon the Investor furnishing in writing to the Company for the purpose of including publicly in the Registration Statement, as applicable, such information regarding the Investor, the securities of the Company held and beneficially owned by the Investor, the intended method of disposition of the Registrable Securities and any other information required to be included in the Registration Statement, as applicable, as shall be reasonably requested by the Company to effect the registration of the applicable securities. The Company shall use its commercially reasonable efforts to have each Registration Statement declared effective by the SEC as soon as practicable, but in no event later than the Effectiveness Deadline. By 9:30 am, New York time on the Business Day following the date of effectiveness, the Company shall file with the SEC in accordance with Rule 424 under the Securities Act, the final Prospectus to be used in connection with sales pursuant to such Registration Statement. Prior to the filing of the Canadian Prospectus Supplement with the Ontario Securities Commission and the Registration Statement with the SEC, the Company shall furnish a draft of the Canadian Prospectus Supplement and the Registration Statement to the Investor for their review and comment. The Investor shall furnish comments on the Canadian Prospectus Supplement and the Registration Statement to the Company within 24 hours of the receipt thereof from the Company. For the purposes hereof, the Investor shall be entitled to deliver a Demand Notice to the Company at any time during the Registration Period if at such time (i) no Registration Statement is then in effect which the Investor may use to resell Registrable

Securities, or (ii) a Registration Statement is effective, but the holder has resold substantially all of the Common Shares registered on such Registration Statement. In addition, the Investor may deliver a Demand Notice to the Company at any time during the Registration Period during which (i) the Company does not have a class of securities listed, or approved for listing, on a national securities exchange registered pursuant to Section 6 of the Exchange Act, or (ii) Rule 144, as amended, would not allow the “tacking” of the holding period of the Convertible Debenture onto the holding period of the Conversion Shares issuable upon conversion thereof.

(c)Amendments and Supplements. During the Registration Period, subject to Allowable Grace Periods (as defined in Section 2(g) below), the Company shall use commercially reasonable efforts to (i) promptly prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement, as applicable, and the Prospectus used in connection with a Registration Statement, which Prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act as may be necessary to keep such Registration Statement effective at all times during the Registration Period, (ii) prepare and file with the applicable securities regulators additional Registration Statements, as applicable, in order to register for resale under Securities Laws all of the Registrable Securities in accordance with the terms of this Agreement; (iii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (iv) respond as promptly as reasonably possible to any comments received from the applicable securities regulators with respect to a Registration Statement, Canadian Prospectus Supplement or any amendment thereto and as promptly as reasonably possible provide the Investor true and complete copies of all correspondence from and to the applicable securities regulators relating to a Registration Statement or the Canadian Prospectus Supplement (provided that the Company may excise any information contained therein which would constitute material non-public information as to any Investor which has not executed a confidentiality agreement with the Company); and (v) comply with the provisions of Applicable Securities Laws with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement including the Prospectus Supplement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 2(c)) by reason of the Company’s filing a report on Form 40-F, or Form 6-K or any analogous report under the Securities Exchange Act, the Company shall incorporate such report by reference into the Registration Statement, as and if applicable, or shall file such amendments or supplements with the SEC on the same day on which the Exchange Act report is filed which created the requirement for the Company to amend or supplement the Registration Statement.

(d)Reduction of Registrable Securities Included in a Registration Statement. Notwithstanding anything contained herein, in the event that the SEC requires the Company to reduce the number of Registrable Securities to be included in a Registration Statement in order to allow the Company to rely on Rule 415 with respect to a Registration Statement, then the Company shall be obligated to include in such Registration Statement (which may be a subsequent Registration Statement if the Company needs to withdraw a Registration Statement and refile a new Registration Statement in order to rely on Rule 415) only such limited portion of the Registrable Securities as the SEC shall permit. Any Registrable Securities that are excluded in accordance with the foregoing terms are hereinafter referred to as “Cut Back Securities.” To the extent Cut Back Securities exist, promptly following such time as may be permitted by the SEC, the Company shall be required to file a Registration Statement covering the resale of the Cut Back Securities (subject also to the terms of this Section 2) and shall use its best efforts to cause such Registration Statement to be declared effective as promptly as practicable thereafter, but in no event later than the Effectiveness Deadline. Notwithstanding the foregoing to the

contrary, the Company shall be obligated to use diligent efforts to advocate with the SEC for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance and Disclosure Interpretation 612.09. Unless otherwise directed in writing by a holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced as follows: (i) first, the Company shall reduce or eliminate any securities to be included other than Registrable Securities; and (ii) second, the Company shall reduce Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by such holders (or as otherwise expressly directed by the SEC).

(e)Piggy-Back Registrations. If at any time there is not an effective Registration Statement covering all of the Registrable Securities and the Company proposes to register the offer and sale of any Common Shares under Applicable Securities Laws (other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering, business combination transaction, acquisition or sale to employees or directors of the Company pursuant to any employee share plan or other employee benefit arrangement), (ii) pursuant to a Registration Statement on Form F-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account or for the account of one or more shareholders of the Company and the form of Registration Statement to be used may be used for any registration of Registrable Securities, the Company shall give prompt written notice (in any event no later than five days prior to the filing of such Registration Statement) to the holders of Registrable Securities of its intention to effect such a registration and, shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion from the holders of Registrable Securities within two days of receipt of notice from the Company; provided, however, that, the Company shall not be required to register any Registrable Securities pursuant to this Section 2(e) that have been sold or may be sold without any restrictions pursuant to Rule 144, as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s transfer agent.

(f)Allowable Grace Period. Notwithstanding anything to the contrary contained herein, upon the advice of Company counsel in the form of a written opinion, at any time after the Effective Date of a particular Registration Statement, the Company may, upon written notice to the Investor, suspend the Investor’s use of any Prospectus (in which event the Investor shall discontinue sales of any Registrable Securities pursuant to such Registration Statement contemplated by this Agreement, but shall settle any previously made sales of Registrable Securities) if the Company (x) is pursuing an acquisition, merger, tender offer, reorganization, disposition or other similar transaction and the Company determines in good faith that (A) the Company’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in such Registration Statement or other registration statement or (B) such transaction renders the Company unable to comply with Applicable Securities Laws, in each case under circumstances that would make it impractical or inadvisable to cause any Registration Statement (or such filings) to be used by the Investor or to promptly amend or supplement any Registration Statement contemplated by this Agreement on a post effective basis, as applicable, or (y) has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Company, would materially adversely affect the Company (each, an “Allowable Grace Period”); provided, however, that, subject to the terms of this Agreement, in no event shall the Investor be suspended from selling Registrable Securities pursuant to any Registration Statement for a period that exceeds twenty (20) consecutive calendar days or an aggregate of forty (40) calendar days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice, but in any event within one Business Day of such disclosure or termination, to the Investor and shall promptly

terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 6(a), the Company, each of its directors, each of its officers, employees, representatives, or agents and each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (each an “Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or is based upon any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 6(d), such Investor will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld; provided, further, however, that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the prospectus was corrected and such new prospectus was delivered to each Investor prior to such Investor’s use of the prospectus to which the Claim relates.

(c)Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than one (1) counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified

Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

(d)The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.

(e)The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

7.CONTRIBUTION.

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Applicable Securities Laws) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

8.REPORTS UNDER THE EXCHANGE ACT.

With a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any similar rule or regulation of the SEC that may at any time permit the Investor to sell securities of the Company to the public without registration, and as a material inducement to the Investor’s purchase of the Convertible Debentures, the Company represents, warrants, and covenants to the following:

(a)The Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act and has filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months prior to the date hereof (or for such shorter period that the issuer was required to file such reports), other than Form 6-K reports.

(b)During the Registration Period, the Company shall use its commercially reasonable efforts to file with the SEC in a timely manner all required reports under Section 13 or 15(d) of the Exchange Act (it being understood that nothing herein shall limit the Company’s obligations under the Securities Purchase Agreement) and such reports shall conform to the requirement of the Exchange Act and the SEC for filing thereunder.

(c)The Company shall furnish to the Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company,

and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without registration.

9.AMENDMENT OF REGISTRATION RIGHTS.

Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Investor. Any amendment or waiver effected in accordance with this Section 9 shall be binding upon the Investor and the Company. No such amendment shall be effective to the extent that it applies to fewer than all of the holders of the Registrable Securities. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to all of the parties to this Agreement.

10.MISCELLANEOUS.

(a)A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable Securities or owns the right to receive the Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

(b)The Company shall not file any other registration statements on Form F-10, F-3 or F-1, or otherwise until the initial Registration Statement required hereunder is declared effective by the SEC, provided that this Section 10(b) shall not prohibit the Company from filing amendments to registration statements already filed. The Company shall not include any other securities on a Registration Statement unless otherwise agreed by the Investor.

(c)Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered pursuant to the notice provisions of the Securities Purchase Agreement or to such other address and/or electronic mail address and/or to the attention of such other person as the recipient party has specified by written notice given to each other party five (5) days prior to the effectiveness of such change. Written confirmation of receipt (A) given by the recipient of such notice, consent, waiver or other communication, (B) electronically generated by the sender’s email service provider containing the time, date, and recipient email or (C) provided by a courier or overnight courier service shall be rebuttable evidence of personal service, receipt by facsimile or receipt from a nationally recognized overnight delivery service in accordance with this section.

(d)Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

(e)The laws of the State of New York shall govern all issues concerning the relative rights of the Company and the Investors as its shareholders. All other questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. Each party hereby irrevocably submits to the non-exclusive jurisdiction of the

Supreme Court of the State of New York, sitting in New York County, New York and federal courts for the Southern District of New York sitting New York, New York, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(f)This Agreement and the rights, duties and obligations of the Investor hereunder may only be assigned upon the transfer of a Convertible Debenture or the Conversion Shares issued pursuant to a Convertible Debenture pursuant to the terms and restrictions on transfer set forth in the Securities Purchase Agreement and the applicable Convertible Debenture. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors and the permitted assigns of the parties. No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (A) written notice of such assignment and (B) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement).

(g)The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(h)This Agreement may be executed in identical counterparts, both which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party.

(i)Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

(j)The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent and no rules of strict construction will be applied against any party.

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Buyer hereby agree as follows:

1.PURCHASE AND SALE OF CONVERTIBLE NOTE.

(a)Purchase of Convertible Note. Subject to the satisfaction (or waiver) of the respective conditions set forth in Sections 6 and 7 below, the Company shall issue and sell to the Buyer, and the Buyer agrees to purchase from the Company at Closing the Convertible Note in a principal amount equal to the Subscription Amount.

(b)Closing Date. The Closing shall occur remotely by conference call and electronic delivery of documentation. The Closing shall occur at or about 8:00 a.m., New York time, on the first Business Day on which the conditions to the Closing set forth in Sections 6 and 7 below are satisfied or waived (or such other date as is mutually agreed to by the Company and the Buyer) (the “Closing Date”).

The Company may issue the relevant Conversion Shares upon conversion of any outstanding Convertible Note without regard to the limitations imposed by the NYSE American. So long as any Convertible Note is outstanding, the Company shall comply with the Home Country Practice rules and shall not take any action to change its Home Country Practice or become subject to the NYSE American shareholder approval rules with respect to transactions contemplated herein. The Company’s practices in connection with the transactions contemplated hereunder are not prohibited by its home country’s laws and are not subject to shareholder approval under the rules, regulations and requirements of the Cboe Canada (“Cboe”).

2.BUYER’S REPRESENTATIONS AND WARRANTIES.

The Buyer represents and warrants to the Company that as of the date hereof and as of the Closing Date:

(a)Investment Purpose. The Buyer is acquiring the Securities for its own account for investment purposes and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered under or exempt from the registration requirements of the Securities Act; provided, however, that by making the representations herein, the Buyer does not agree, or make any representation or warranty, to hold any of the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with, or pursuant to, a registration statement covering such Securities or an available exemption under the Securities Act. The Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of the Securities in violation of Applicable Securities Laws. As used herein,

“Person” means a corporation, a limited liability company, an association, a partnership, an organization, a business, an individual, governmental or political subdivision thereof or a governmental agency. As used herein, “Applicable Securities Laws” means (a) the applicable securities laws of each of the provinces and territories of Canada, their respective regulations, rulings, rules, orders (including blanket orders and discretionary orders), instruments (including national and multilateral instruments), fee schedules and prescribed forms thereunder, and the applicable policy statements issued by the applicable securities commissions or regulatory authority or similar authority thereunder (“Canadian Securities Laws”) and (b) all applicable securities laws in the United States, including, without limitation, the Securities Act, the Exchange Act and the rules and regulations promulgated thereunder, and any applicable state securities laws (“U.S. Securities Laws”).

(b)Accredited Investor Status. The Buyer is an “Accredited Investor” as that term is defined in Rule 501(a)(3) of Regulation D.

(c)Reliance on Exemptions. The Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from: (i) the registration requirements of U.S. Securities Laws; and (ii) the exemption from the prospectus requirements of the Securities Act (Ontario) under Section 2.3 of OSC Rule 72-503, and that, in each case, the Company is relying in part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the Securities.

(d)Information. The Buyer has been furnished with all materials relating to the business, finances and operations of the Company and information the Buyer deemed material to making an informed investment decision regarding its purchase of the Securities, which have been requested by the Buyer. The Buyer has been afforded the opportunity to ask questions of the Company and its management and has received answers to such questions. Neither such inquiries nor any other due diligence investigations conducted by the Buyer or its representatives shall modify, amend or affect the Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Buyer understands that its investment in the Securities involves a high degree of risk. The Buyer has sought such accounting, legal and tax advice, as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. The Buyer acknowledges and agrees that the Company does not make and has not made any representation or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.

(e)Transfer or Resale. The Buyer understands that: (i) the Securities have not been registered under U.S. Securities Laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) the Buyer shall have delivered to the Company an opinion of counsel, in a form generally acceptable to the Company and the Company’s transfer agent, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration requirements, (C) the Buyer provides the Company with reasonable assurances (in the form of seller and broker representation letters reasonably acceptable to the Company) that such Securities can be sold, assigned or transferred pursuant to Rule 144 promulgated under the Securities Act, as amended (or a successor rule thereto) (collectively, “Rule 144”), in each case following the applicable holding period set forth therein; or (D) the Buyer shall have delivered to the Company and the Company’s transfer agent and Rule 904 declaration in a form agreed to by the Company and the Company’s transfer agentand (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term

is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation, this Section 2(e). In addition, the Buyer understands that (i) the Securities have not been qualified for distribution by prospectus in any jurisdiction of Canada, and may not be offered for sale, sold, assigned or transferred in any jurisdiction of Canada during the course of the distribution thereof, except pursuant to a prospectus or exemption from the prospectus requirement under Canadian Securities Laws. The Buyer covenants and agrees that it shall not directly or indirectly, during the course of the distribution of the distribution of the Securities, make any offers or sales of securities in connection with this Agreement directly to any person whom, to the Buyer’s knowledge, is (A) a person resident or located in a jurisdiction of Canada; (B) a person acquiring such securities for the benefit of another person resident or located in a jurisdiction of Canada, or (C) on any “marketplace” (as such term is defined in National Instrument 21-101 – Marketplace Operation) in Canada. The Company and the Buyer shall take all further steps reasonably required to ensure compliance with the provisions of OSC Rule 72-503. For clarity, a distribution made on or through the facilities of an exchange or market outside Canada is a distribution to a person or company outside Canada if neither the seller nor any person acting on its behalf has reason to believe that the distribution has been pre-arranged with a buyer in Canada.

(f)Legends. The Buyer agrees to the imprinting, so long as its required by this Section 2(f), of a restrictive legend on the Securities in substantially the following form:

THE SECURITIES REPRESENTED HEREBY [for Convertible Note add: AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE] HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TOWARD RESALE AND MAY ONLY BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS, (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN THE CASE OF SUBPARAGRAPH (C) OR (D), THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING OR SUCH OTHER EVIDENCE AS THE CORPORATION MAY REQUIRE IN FORM AND

SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.

Subject to the provision of representation letters from the Buyer and its representatives as the Company may require, certificates evidencing the Conversion Shares shall not contain any legend (including the legend set forth above), (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Conversion Shares pursuant to Rule 144, (iii) if such Conversion Shares are eligible for sale under Rule 144, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than one (1) Trading Days (as defined in the Convertible Note) (or such earlier date as required pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or other applicable law, rule or regulation for the settlement of a trade initiated on the date the Buyer delivers such legended certificate representing such securities to the Company) following the delivery by a Buyer to the Company or the transfer agent (with notice to the Company) of a legended certificate representing such securities (endorsed or with stock powers attached, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from the Buyer as may be required above in this Section 2(f), as directed by the Buyer, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated Securities Transfer Program, credit the aggregate number of shares of Common Shares to which the Buyer shall be entitled to the Buyer’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to the Buyer, a certificate representing such securities that is free from all restrictive and other legends, registered in the name of the Buyer or its designee. The Company shall be responsible for any transfer agent fees or DTC fees with respect to any issuance of Securities or the removal of any legends with respect to any Securities in accordance herewith. The Buyer agrees that the removal of a restrictive legend from certificates representing Securities as set forth in this Section 2(f) is predicated upon the Company’s reliance that the Buyer will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

(g)Organization; Authority.

The Company and each of its Subsidiaries is qualified to do business and is in good standing or subsisting (with respect to jurisdictions that recognize the concept of good standing or subsisting) as a foreign legal entity in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material Adverse Effect (as defined below). As used in this Agreement, “Material Adverse Effect” means any material adverse effect on (i) the business, properties, assets, liabilities, operations (including results thereof), condition (financial or otherwise) or prospects of the Company and its Subsidiaries, taken as a whole, (ii) the transactions contemplated hereby or in any of the other Transaction Documents or any other agreements or instruments to be entered into by the Company in connection herewith or therewith or (iii) the authority or ability of the Company to perform any of its obligations under any of the Transaction Documents. “Subsidiaries” means Cybin Corp., Cybin US Holdings Inc., Adelia Therapeutics, Cybin IRL Limited (“Cybin IRL”), and Cybin UK Ltd., and any subsidiary that after the date of this Agreement becomes a “significant subsidiary” of the Company (as defined in Rule 1-02(w) of Regulation S-X under the Exchange Act), and each of the foregoing, is individually referred to herein as a “Subsidiary.”

The execution and delivery of this Agreement and the other Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Convertible Note, the reservation for issuance and issuance of the Conversion Shares issuable upon conversion of the Convertible Note), have been duly authorized by the Company’s board of directors and no further filing, consent or authorization is required by the Company, its board of directors or its shareholders or other governmental body. This Agreement has been, and the other Transaction Documents to

which the Company is a party will be prior to the Closing, duly executed and delivered by the Company, and each constitutes the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with its respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies and except as rights to indemnification and to contribution may be limited by U.S. Securities Laws. “Transaction Documents” means, collectively, this Agreement, the Registration Rights Agreement, the Convertible Note, and each of the other agreements and instruments entered into by the Company or delivered by the Company in connection with the transactions contemplated hereby and thereby, as may be amended from time to time.

Upon issuance or conversion in accordance with the Convertible Note, the Conversion Shares, when issued, will be validly issued, fully paid and nonassessable and free from all pre-emptive or similar rights or Liens with respect to the issue thereof, with the holders being entitled to all rights accorded to a holder of Common Shares.

(d)No Conflicts.

(f)Exchange Approvals. At the Closing Date, the Company has made all required submissions to Principal U.S. Market to reserve 16,500,000 Common Shares and shall have not received any notice objecting to the listing of these Common Shares from the Principal U.S. Market. Prior to the Closing Date, the Company shall have received the conditional approval of the Cboe to the transactions contemplated herein, in form and substance satisfactory to the Buyer acting reasonably.

(g)Acknowledgment Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees that the Buyer is acting solely in the capacity of an arm’s-length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of the Company or any of its Subsidiaries, (ii) to its knowledge, an “affiliate” (as defined in Rule 144 promulgated under the Securities Act (or a successor rule thereto) (collectively, “Rule 144”)) of the Company or any of its Subsidiaries or (iii) to its knowledge, a “beneficial owner” of more than 10% of the Common Shares (as defined for purposes of Rule 13d­3 of the Exchange Act). The Company further acknowledges that no Buyer (nor any affiliate of any Buyer) is acting as a financial advisor or fiduciary of the Company or any of its Subsidiaries (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to the Buyer’s purchase of the Securities. The Company further represents to the Buyer that the Company’s decision to enter into the Transaction Documents to which it is a party has been based solely on the independent evaluation by the Company and its representatives.

(h)No Integrated Offering. None of the Company, its Subsidiaries or any of their affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to require approval of shareholders of the Company under any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated for quotation, other than as set forth herein. None of the Company, its Subsidiaries, their affiliates nor any Person acting on their behalf will take any action or steps that would cause the offering of any of the Securities to be integrated with other offerings of securities of the Company.

(i)Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares will increase in certain circumstances and could cause dilution to existing shareholders.

(j)Continuous Disclosure Materials; Financial Statements. During the two (2) years prior to the date hereof, and, as applicable, the Closing Date, the Company has timely filed, or will have timely filed, all reports, schedules, forms, proxy statements, statements and other documents required to be filed by it under Applicable Securities Laws (all of the foregoing filed prior to the date hereof and, as applicable, the Closing Date and all exhibits and appendices included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “Continuous Disclosure Materials”). The Company has delivered or has made available to the Buyer or its representatives true, correct and complete copies of each of the Continuous Disclosure Materials not available on the EDGAR system or SEDAR+ system. As of their respective dates, the Continuous Disclosure Materials complied in all material respects with the requirements of the Applicable Securities Laws applicable to the Continuous Disclosure Materials, and none of the

Continuous Disclosure Materials, at the time they were filed on the EDGAR system or SEDAR+ system (subject to amendments thereto), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the Continuous Disclosure Materials complied in all material respects with applicable accounting requirements and the Applicable Securities Laws with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IFRS”), consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year­end audit adjustments which will not be material, either individually or in the aggregate). The reserves, if any, established by the Company or the lack of reserves, if applicable, are reasonable based upon facts and circumstances known by the Company on the date hereof and there are no loss contingencies that are required to be accrued by the applicable financial accounting standards of the Financial Accounting Standards Board which are not provided for by the Company in its financial statements or otherwise. No other information provided by or on behalf of the Company to the Buyer which is not included in the Continuous Disclosure Materials contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstance under which they are or were made, not misleading. The Company is not currently contemplating to further amend or restate any of the financial statements (including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included in the Continuous Disclosure Materials (the “Financial Statements”), nor is the Company currently aware of facts or circumstances which would require the Company to further amend or restate any of the Financial Statements, in each case, in order for any of the Financial Statements to be in compliance with IFRS and the rules and regulations of the SEC. The Company has not been informed by its independent accountants that they recommend that the Company amend or restate any of the Financial Statements or that there is any need for the Company to amend or restate any of the Financial Statements.

(k)Absence of Certain Changes. Since the date of the Company’s most recent audited financial statements that are available on the SEC’s website through the EDGAR system or through the SEDAR+ system (the “Prior Annual Financial Statements”), there has been no Material Adverse Effect, nor any event or occurrence specifically affecting the Company or its Subsidiaries that would be reasonably expected to result in a Material Adverse Effect. Since the date of the Prior Annual Financial Statements, neither the Company nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any material assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any material capital expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company or any Subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so.

(l)No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or exists, or is reasonably expected to exist or occur specific to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition

(financial or otherwise), that has not been publicly disclosed and would reasonably be expected to have a Material Adverse Effect.

(m)Conduct of Business; Regulatory Permits. Neither the Company nor any of its Subsidiaries is in violation of any term under its certificate of incorporation, any certificate of designation, preferences or rights of any other outstanding series of preferred shares of the Company or any of its Subsidiaries or Articles or their organizational charter, certificate of formation, memorandum of association, articles of association, certificate of incorporation or articles, respectively. Neither the Company nor any of its Subsidiaries is in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company nor any of its Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for violations which would not reasonably be expected to have a Material Adverse Effect. Without limiting the generality of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of Principal U.S. Market or Cboe and has no knowledge of any facts or circumstances that could reasonably lead to delisting or suspension of the Common Shares by Principal U.S. Market or Cboe in the foreseeable future. During the one year prior to the date hereof, (i) the Common Shares have been listed or designated for quotation on Principal U.S. Market and Cboe, (ii) trading in the Common Shares has not been suspended by Principal U.S. Market or Cboe, and (iii) the Company has received no communication, written or oral, from Principal U.S. Market or Cboe regarding the suspension or delisting of the Common Shares from Principal U.S. Market or Cboe, which has not been publicly disclosed. The Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit. There is no agreement, commitment, judgment, injunction, order or decree binding upon the Company or any of its Subsidiaries or to which the Company or any of its Subsidiaries is a party which has or would reasonably be expected to have the effect of prohibiting or materially impairing any business practice of the Company or any of its Subsidiaries, any acquisition of property by the Company or any of its Subsidiaries or the conduct of business by the Company or any of its Subsidiaries as currently conducted other than such effects, individually or in the aggregate, which have not had and would not reasonably be expected to have a Material Adverse Effect on the Company or any of its Subsidiaries.

(n)Foreign Corrupt Practices. Except as, individually or in the aggregate, would not reasonably be expected to be material to the Company and the Subsidiaries, taken as a whole, since January 1, 2021, none of the Company or the Subsidiaries, nor any director, manager, officer, employee, or, to the actual knowledge of the Company, agent or representative of the Company or any of the Subsidiaries, has directly or indirectly through another person made, offered to make, attempted to make, or accepted any contribution, gift, bribe, rebate, payoff, influence payment, kickback or other payment to or from any person, private or public, regardless of what form, whether in money, property or services, in violation of the U.S. Foreign Corrupt Practices Act of 1977, as amended, the Corruption of Foreign Public Officials Act (Canada), as amended, and any foreign or other anti-bribery or anti-corruption laws (collectively, “Anti-Corruption Laws”). Since January 1, 2021, none of the Company or any of the Subsidiaries, or any of their respective directors, officers, employees or representatives has been under internal or, to the actual knowledge of the Company, any federal, state, provincial, local, foreign or supranational government, any court, legislative, administrative, regulatory or other governmental agency, commission or authority or any non-governmental self-regulatory agency, commission or authority or any stock exchange (each, a “Governmental Entity”) investigation for any material violation of any Anti-Corruption Laws or has received any written notice or other communication from any Governmental Entity regarding a violation of, or failure to

comply with, any Anti-Corruption Laws. Since January 1, 2021, the Company and the Subsidiaries have implemented, maintained and enforced an adequate system or systems of internal controls reasonably designed to ensure compliance with the Anti-Corruption Laws and prevent and detect violations of the Anti-Corruption Laws. Since January 1, 2021, neither the Company nor any of the Subsidiaries has made any disclosure (voluntary or otherwise) to any Governmental Entity with respect to any alleged irregularity, misstatement or omission or other potential violation or liability arising under or relating to any Anti-Corruption Laws.

(o)Equity Capitalization. As of the date hereof, the authorized capital of the Company consists of an unlimited number of Common Shares and an unlimited number of preferred shares. As of the date hereof, the Company had 23,023,631 Common Shares outstanding. As of the date of the Closing, the authorized share capital of the Company will be an unlimited number of Common Shares. The Common Shares are registered pursuant to Section 12(b) of the Exchange Act and are listed on a Principal U.S. Market. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Shares under the Exchange Act, delisting the Common Shares from the Principal U.S. Market, nor has the Company received any notification that the SEC or the Principal U.S. Market is contemplating terminating such registration or listing. To the Company’s knowledge, it is in compliance with all applicable listing requirements of the Principal U.S. Market. For the purposes of this Agreement, “Principal U.S. Market” shall mean the NYSE American; provided however, that in the event the Common Shares are ever listed or traded on the New York Stock Exchange, or the Nasdaq Stock Market, then the “Principal U.S. Market” shall mean such other market or exchange on which the Common Shares are then listed or traded to the extent such other market or exchange is the principal trading market or exchange for the Common Shares in the United States.

(p)Existing Securities; Obligations. Except as disclosed in the Continuous Disclosure Materials or as disclosed by the Company to the Buyer, (A) none of the Company’s or any Subsidiary’s shares, interests or capital stock is subject to pre-emptive rights or any other similar rights or Liens suffered or permitted by the Company or any Subsidiary; (B) there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, or exercisable or exchangeable for, any shares, interests or capital stock of the Company or any of its Subsidiaries, or contracts, commitments, understandings or arrangements by which the Company or any of its Subsidiaries is or may become bound to issue additional shares, interests or capital stock of the Company or any of its Subsidiaries or options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, or exercisable or exchangeable for, any shares, interests or capital stock of the Company or any of its Subsidiaries; (C) there are no agreements or arrangements under which the Company or any of its Subsidiaries is obligated to register the sale of any of their securities under the Securities Act (except pursuant to (i) this Agreement, and (ii) the Registration Rights Agreement; (D) there are no outstanding securities or instruments of the Company or any of its Subsidiaries which contain any redemption or similar provisions, and there are no contracts, commitments, understandings or arrangements by which the Company or any of its Subsidiaries is or may become bound to redeem a security of the Company or any of its Subsidiaries; (E) there are no securities or instruments containing anti­dilution or similar provisions that will be triggered by the issuance of the Securities; and (F) neither the Company nor any Subsidiary has any stock appreciation rights or “phantom stock” plans or agreements or any similar plan or agreement.

Except as disclosed by the Company in the Continuous Disclosure Materials, there is no action, suit, arbitration, proceeding, inquiry or investigation before or by NYSE American, Cboe, any court, public board, other Governmental Entity, self­regulatory organization or body pending or, to the knowledge of the Company, threatened against or affecting the Company or, to the knowledge of the Company, any of its Subsidiaries, the Common Shares or any of the Company’s or its Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such, which would reasonably be expected to result in a Material Adverse Effect.

Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for, and neither the Company nor any such Subsidiary has any reason to believe that it will be unable to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(t)Manipulation of Price. Neither the Company nor any of its Subsidiaries has, and, to the knowledge of the Company, no Person acting on their behalf has, directly or indirectly, (i) taken any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company or any of its Subsidiaries to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase any other securities of the Company or any of its Subsidiaries.

Company. None of the disclosures provided to the Buyer regarding the Company and its Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Agreement (if any), furnished by or on behalf of the Company or any of its Subsidiaries, taken as a whole, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

(k)Indemnification.

(i)In consideration of the Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Buyer and all of their shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Buyer Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and reasonable and documented expenses in connection therewith (irrespective of whether any the Buyer Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Buyer Indemnitee as a result of, or arising out of, or relating to (i) any material misrepresentation or material breach of any representation or warranty made by the Company in any of the Transaction Documents, or (ii) any material breach of any material covenant, material agreement or material obligation of the Company or any Subsidiary contained in any of the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(ii)In consideration of the Company’s execution and delivery of the Transaction Documents and in addition to the Buyer’s obligations under the Transaction Documents, the Buyer shall defend, protect, indemnify and hold harmless the Company and its shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Company Indemnitees”) from and against any and all Indemnified Liabilities, incurred by any Company Indemnitees as a result of, or arising out of, or relating to (i) any misrepresentation or breach of any representation or warranty made by the Buyer in any of the Transaction Documents, or (ii) any material breach of any material covenant, material agreement or material obligation of the Buyer contained in any of the Transaction Documents. To the extent that

the foregoing undertaking by the Buyer may be unenforceable for any reason, the Buyer shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(iii)Promptly after receipt by a Buyer Indemnitee or Company Indemnitee under this Section 9(i) of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, the Buyer Indemnitee or Company Indemnitee shall, if a claim in respect thereof is to be made against the Company or a Buyer under this Section 9(i), deliver to the Company or Buyer, as applicable, a written notice of the commencement thereof, and the Company or Buyer shall have the right to participate in, and, to the extent the Company or Buyer, as applicable so desires, to assume control of the defense thereof with counsel mutually reasonably satisfactory to the Company or Buyer and the Buyer Indemnitee or Company Indemnitee, as applicable; provided, however, that a Buyer Indemnitee or Company Indemnitee shall have the right to retain its own counsel with the actual and reasonable fees and expenses of such counsel to be paid by the Company or Buyer, if applicable, if: (A) the Company or Buyer has agreed in writing to pay such fees and expenses; (B) the Company or Buyer shall have failed promptly to assume the defense of such Indemnified Liability and to employ counsel reasonably satisfactory to the Buyer Indemnitee or Company Indemnitee in any such Indemnified Liability; or (C) the named parties to any such Indemnified Liability (including any impleaded parties) include both the Buyer Indemnitee or Company Indemnitee and the Company or Buyer, as applicable, and the Buyer Indemnitee or Company Indemnitee shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnitee and the Company or the Buyer, as applicable (in which case, if the Buyer Indemnitee or Company Indemnitee notifies the Company or Buyer, as applicable, in writing that it elects to employ separate counsel at the expense of the Company or Buyer, as applicable, then the Company or Buyer, as applicable, shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Company or Buyer, as applicable), provided further, that in the case of clause (C) above the Company or Buyer shall not be responsible for the reasonable fees and expenses of more than one separate legal counsel for the Indemnitees. The Buyer Indemnitee or Company Indemnitee shall reasonably cooperate with the Company or Buyer, as applicable, in connection with any negotiation or defense of any such action or Indemnified Liability by the Company or Buyer and shall furnish to the Company or Buyer all information reasonably available to the Indemnitee which relates to such action or Indemnified Liability. The Company or Buyer shall keep the Buyer Indemnitee or Company Indemnitee reasonably apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company or Buyer shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the Company or Buyer shall not unreasonably withhold, delay or condition its consent. The Company or Buyer, as applicable, shall not, without the prior written consent of the Buyer Indemnitee or Company Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the

claimant or plaintiff to the Buyer Indemnitee or Company Indemnitee of a release from all liability in respect to such Indemnified Liability or litigation, and such settlement shall not include any admission as to fault on the part of the Buyer Indemnitee or Company Indemnitee. Following indemnification as provided for hereunder, the Company or Buyer, as applicable, shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the Company or Buyer, as applicable, within a reasonable time of the commencement of any such action shall not relieve the Company or Buyer, as applicable, of any liability to the Buyer Indemnitee or Company Indemnitee under this Section 9(i), except to the extent that the Company or Buyer, as applicable, is materially and adversely prejudiced in its ability to defend such action.

(iv)The indemnification required by this Section 9(i) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within 10 days after bills supporting the Indemnified Liabilities are received by the Company or the Buyer, as applicable.

(v)The indemnity agreement contained herein shall be in addition to (A) any cause of action or similar right of the Buyer Indemnitee or Company Indemnitee against the Company or Buyer, as applicable, or others, and (B) any liabilities the Company or Buyer may be subject to pursuant to applicable law.

(l)No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m)Currency. Unless otherwise specified, all references to “$” or “dollars” in this Agreement means the lawful currency of the United States of America.

Issuance Date: June 30, 2025

Number: CYBN-1

FOR VALUE RECEIVED, CYBIN INC., a corporation organized under the Business Corporations Act (Ontario) (the “Company”), hereby promises to pay to the order of High Trail Special Situations LLC, 290 Harbor Drive, 3rd Floor Stamford, CT 06902 Attn: Capital Solutions or its registered assigns (the “Holder”) the amount set out above as the Original Principal Amount (or such lesser amount as reduced pursuant to the terms hereof pursuant to repayment, redemption, conversion or otherwise, the “Principal”) and the Payment Premium (as defined below), in each case when due, and to pay Pre-Paid Interest Amount (as defined below), whether upon the Maturity Date or acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). The

“Issuance Date” is the date of the first issuance of this Convertible Note (as amended, amended and restated, extended, supplemented or otherwise modified in writing from time to time, this “Note”) regardless of the number of transfers and regardless of the number of instruments, which may be issued to evidence such Note. This Note was originally issued pursuant to the Securities Purchase Agreement dated as of June 30, 2025, between the Company and High Trail Special Situations LLC (as it may be amended from time to time, the “Securities Purchase Agreement”). Certain capitalized terms used herein are defined in Section 14 and the Purchase Agreement.

1.GENERAL TERMS

(a)Maturity Date. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal and any other amounts outstanding pursuant to the terms of this Note, if any. The “Maturity Date” shall be June 30, 2027. Other than as specifically permitted by this Note, the Company may not prepay or redeem any portion of the outstanding Principal.

(b)Pre-Paid Interest. The Company shall pay to the Holder on the Issuance Date the Pre-Paid Interest Amount.

(c)Default Interest. Upon the occurrence of an Event of Default (defined below), interest shall accrue on the outstanding Principal balance at an annual rate of 18% (“Default Interest”), from and including the date of such Event of Default and to the date such Event of Default is cured and all outstanding Default Interest is paid. Default Interest shall be calculated based on a 360-day year and the actual number of days elapsed, to the extent permitted by applicable law and will be payable in arrears on the earlier of (i) the first day of each calendar month, (ii) the date such Event of Default is cured, and (iii) the date on which any portion of the outstanding Principal of this Note is reduced or otherwise retired.

(d)Amortization Event. If, any time after the Issuance Date set forth above, and from time to time thereafter, an Amortization Event has occurred, then the Company shall make monthly cash payments beginning on the fourteenth Trading Day after the Amortization Event Date and continuing on the same day of each successive calendar month (each, an “Amortization Event Payment Date”) until the entire outstanding amounts shall have been repaid. Each monthly cash payment shall be in an amount equal to the sum of (i) the Amortization Principal Amount, plus (ii) the applicable Payment Premium in respect of such Amortization Principal Amount (the “Amortization Amount”). The obligation of the Company to make monthly cash payments related to an Amortization Event shall cease (with respect to any payment that has not yet come due) if at any time after the Amortization Event Date, the condition or event causing the Amortization Event has been cured or the Holder is able to resell the Common Shares issuable upon conversion of this Note in accordance with Rule 144 under the Securities Act, unless a subsequent Amortization Event occurs. Notwithstanding any provision of this Section 1(d) to the contrary, the Holder may, at its option and in its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable Amortization Event Payment Date electing to have the payment of all or any portion of such Amortization Amount payable on such Amortization Event Payment Date deferred to the next subsequent Amortization Event Payment Date.

(e)Optional Prepayment. So long as no Event of Default has occurred and is continuing (or, after notice, passage of time or both, would be an Event of Default), the Company at its option shall have the right, but not the obligation, to prepay (“Optional

Prepayment”) early a portion or all amounts outstanding under this Note as described in this Section; provided, that the Company provides the Holder with written notice (each, a “Prepayment Notice”) of its desire to exercise an Optional Prepayment, which Prepayment Notice shall be delivered to the Holder after the close of regular trading hours on a Trading Day. Each Prepayment Notice shall be irrevocable and shall specify the outstanding balance of the Note to be prepaid and the Prepayment Amount. The “Prepayment Amount” shall be an amount equal to (a) the outstanding Principal balance being prepaid by the Company plus (b) the applicable Payment Premium in respect of such Principal amount. After receipt of a Prepayment Notice, the Holder shall have ten Trading Days (beginning with the Trading Day immediately following the date such Prepayment Notice is delivered to the Holder in accordance with this term of this Section 1(e) to elect to convert all or any portion of this Note. On the eleventh Trading Day following the delivery of the applicable Prepayment Notice, the Company shall deliver to the Holder the Prepayment Amount with respect to the Principal amount redeemed to the extent not converted and otherwise after giving effect to conversions or other payments made during such ten Trading Day period.

(f)Other than as specifically set forth in this Note, the Company shall not have the ability to make any early repayments without the consent of or at the request of the Holder.

(g)Payment Dates. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

(h)Withholding Tax. All amounts paid or credited or deemed to have been paid or credited by or on behalf of the Company under or with respect to this Note or any other Transaction Document (including, without limitation, any penalties, interest and other liabilities related thereto) will be made free and clear of and without withholding, or deduction for, or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other liabilities related hereto) imposed or levied by or on behalf of the Government of Canada or elsewhere, or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Withholding Taxes”), unless the Company is required by law or the interpretation or administration thereof, to withhold or deduct any amounts for, or on account of Withholding Taxes. If the Company determines, in its sole and absolute discretion, that it is so required to withhold or deduct any amount for, or on account of, Withholding Taxes from any amount paid or credited or deemed to have been be paid or credited under or with respect to this Note or any other Transaction Document, the Company shall deduct and withhold such Withholding Taxes from any amount paid or credited or deemed to have been paid or credited under or with respect to this Note or any other Transaction Document and, provided that the Company forthwith remits such amount to the relevant governmental authority or agency, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Company’s obligations under this Note or any other Transaction Document. There is no obligation on the Company to gross-up or pay any additional amounts to any holder of this Note or to any party under any other Transaction Document in respect of such deductions or withholdings. For greater certainty, if any amount is required to be deducted or withheld in respect of Withholding Taxes upon a conversion of this Note, the Company shall be entitled to liquidate (whether directly or through a broker) such number of Common Shares (or other securities) otherwise issuable as a result of such conversion as shall be necessary in order to satisfy such requirement plus any broker or other fees associated with such liquidation. The Company shall provide the applicable holder of this Note with

copies of receipts or other communications relating to the remittance of such withheld amount or the filing of any forms received from such government authority or agency promptly after receipt thereof.  Each holder of this Note and each relevant party shall indemnify and hold the Company harmless from any loss, interest, penalties, tax or other amounts for which the Company may be liable for any failure to deduct, withhold or remit Withholding Taxes in connection with any amount paid or credited or deemed to have been paid or credited under this Note or any other Transaction Document.

(m)Any Event of Default (as defined in the Other Notes or in any Transaction Document other than this Note) occurs with respect to any Other Notes, or any breach of any material term of any other Note, note, or instrument held by the Holder in the Company or any agreement between or among the Company and the Holder and has not been cured within the applicable cure period;

other remedies available to it under applicable law. Such declaration may be rescinded and annulled by the Holder in writing at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

3.CONVERSION OF NOTE.    This Note shall be convertible into Common Shares, on the terms and conditions set forth in this Section 3.

(a)Conversion Right. Subject to the limitations of Section 3(c), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and non-assessable Common Shares in accordance with Section 3(b), at the Conversion Price. The number of Common Shares issuable upon conversion of any Conversion Amount pursuant to this Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price. The Company shall not issue any fraction of a Common Shares upon any conversion. All calculations under this Section 4 shall be rounded to the nearest $0.0001. If the issuance would result in the issuance of a fraction of a Common Share, the Company shall round such fraction of a Common Share down to the nearest whole Common Share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Shares upon conversion of any Conversion Amount, unless such taxes are due because the Holder requests such Common Shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay such taxes.

(b)Mechanics of Conversion.

(a)Optional Conversion. To convert any Conversion Amount into Common Shares on any date (a “Conversion Date”), the Holder shall (A) transmit by email (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and (B) if required by Section 3(b)(iii), surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Note in the case of its loss, theft or destruction). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) if legends are not required to be placed on certificates or the book-entry position of the Common Shares and provided that the Company’s transfer agent is participating in the Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program, instruct such transfer agent to credit such aggregate number of Common Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate or book-entry position, registered in the name of the Holder or its designee, for the number of Common Shares to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant to rules and regulations of the Commission. If this Note is physically surrendered for conversion and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note representing the outstanding Principal not converted. The Person or Persons entitled to receive the Common Shares issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such Common Shares

upon the transmission of a Conversion Notice; provided, that the Holder shall be deemed to have waived any voting rights of any such Conversion Shares that may arise during the period commencing on such Conversion Date, through, and including, such applicable Share Delivery Deadline, as necessary, such that the aggregate voting rights of any Common Shares (including such Conversion Shares) beneficially owned by the Holder and/or any Attribution Parties, collectively, shall not exceed the Beneficial Ownership Limitation (as defined below) as a result of any such conversion of this Note.

(b)Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable Share Delivery Date to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of Common Shares to which the Holder is entitled upon such Holder’s conversion of any Conversion Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Common Shares issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the Common Shares so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Shares to which the Holder is entitled with respect to such Conversion Notice and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Common Shares, multiplied by (B) the Closing Price on the Conversion Date.

(c)Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon any conversion.

(d)Limitations on Conversions.

(a)Beneficial Ownership. The Company shall not effect any conversion of this Note, and a Holder shall not have the right to convert any portion of this Note, to the extent that after giving effect to the conversion set forth on the applicable notice of conversion, the Holder (together with the Holder’s affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder and its affiliates and Attribution Parties shall include the number of Common Shares issuable upon conversion of this Note with respect to which such determination is being made, but shall exclude the number of Common Shares which would be issuable upon (i) conversion of the remaining, unconverted principal amount of this Note (plus, if applicable, any accrued and unpaid interest thereon) beneficially owned by the Holder or any of its affiliates or Attribution

(b)Other Provisions.

(a)All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.

(b)Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company’s failure to deliver certificates representing Common Shares upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(c)Legal Opinions. The Company is obligated to cause its legal counsel to deliver legal opinions to the Company’s transfer agent in connection with any legend removal upon the expiration of any holding period or other requirement for which the Underlying Shares may bear legends restricting the transfer thereof. To the extent a legal opinion is not provided (either timely or at all), then, in addition to being an Event of Default hereunder, the Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with the sale or transfer of the Underlying Shares. The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

(d)Adjustment of Conversion Price upon Subdivision or Combination of Common Shares. If the Company, at any time while this Note is outstanding, shall (i) pay a stock dividend or otherwise make a distribution or distributions on its Common Shares or any other equity or equity equivalent securities payable in Common Shares, (ii) subdivide outstanding Common Shares into a larger number of shares, (iii) combine (including by way of reverse stock split) outstanding Common Shares into a smaller number of shares, or (iv) issue by reclassification of Common Shares any shares of capital stock of the Company, then the Fixed Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of Common Shares outstanding after such event. Any adjustment made pursuant to this Section shall become effective, in the case of a dividend distribution, immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution or, in the case of a subdivision, combination or re-classification, and shall become effective immediately after the effective date of such subdivision, combination or re-classification.

(e)Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option, (i) in addition to the Common Shares receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such Common Shares had such Common Shares been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the Common Shares otherwise receivable upon such conversion, such securities or other assets received by the holders of Common Shares in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to Common Shares) at a conversion rate for such consideration commensurate with the Conversion Price. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or prepayment of this Note.

(f)Whenever the Conversion Price is adjusted pursuant to this Section 3, the Company shall promptly provide the Holder with a written notice setting forth the

Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(g)In case of any (1) merger or consolidation of the Company or any Subsidiary of the Company with or into another Person, or (2) sale by the Company or any Subsidiary of the Company of more than one-half of the assets of the Company in one or a series of related transactions, a Holder shall have the right to (A) exercise any rights under Section 3(f), (B) convert the aggregate amount of this Note then outstanding into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Shares following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the Common Shares into which such aggregate Principal amount of this Note could have been converted immediately prior to such merger, consolidation or sales would have been entitled, or (C) in the case of a merger or consolidation, require the surviving entity to issue to the Holder a convertible Note with a Principal amount equal to the aggregate Principal amount of this Note then held by such Holder, plus all other amounts owing thereon, which such newly issued convertible Note shall have terms identical (including with respect to conversion) to the terms of this Note, and shall be entitled to all of the rights and privileges of the Holder of this Note set forth herein and the agreements pursuant to which this Note was issued. In the case of clause (C), the conversion price applicable for the newly issued convertible debentures or convertible Notes shall be based upon the amount of securities, cash and property that each Common Share would receive in such transaction and the Conversion Price in effect immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger, sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or prepayment following such event. This provision shall similarly apply to successive such events.

4.REISSUANCE OF THIS NOTE.

(a)Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 4(d)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder and, if less than the entire outstanding Principal is being transferred, a new Note (in accordance with Section 4(d)) to the Holder representing the outstanding Principal not being transferred.

NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

This Note may only be transferred, upon compliance with the conditions prescribed in Exhibit II.

(d)Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Note, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and substance and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and deliver to the Holder a new Note (in accordance with Section 4(d)) representing the outstanding Principal.

(e)Note Exchangeable for Different Denominations.

(f)Issuance of New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 4(a) or Section 4(c), the Principal designated by the Holder which, when added to the Principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such

issuance of new Notes), (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of this Note, and (iv) shall have the same rights and conditions as this Note.

8.CHOICE OF LAW; VENUE; WAIVER OF JURY TRIAL

(a)Governing Law.

(b)Jurisdiction; Venue; Service.

(a)The Company hereby irrevocably consents to the non-exclusive personal jurisdiction of the state courts of the Governing Jurisdiction and, if a basis for federal jurisdiction exists, the non-exclusive personal jurisdiction of any United States District Court for the Governing Jurisdiction.

(b)The Company agrees that venue shall be proper in any court of the Governing Jurisdiction selected by the Holder or, if a basis for federal jurisdiction exists, in any United States District Court in the Governing Jurisdiction selected by the Holder. The Company waives any right to object to the maintenance of any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, in any of the state or federal courts of the Governing Jurisdiction on the basis of improper venue or inconvenience of forum.

(c)Any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or tort or otherwise, brought by the Company against the Holder arising out of or based upon this Note or any matter relating to this Note, or any other Transaction Document, or any contemplated transaction, shall be brought in a court only in the Governing Jurisdiction. The Company shall not file any counterclaim against the Holder in any suit, claim, action, litigation or proceeding brought by the Holder against the Company in a jurisdiction outside of the Governing Jurisdiction unless under the rules of the court in which the Holder brought such suit, claim, action, litigation or proceeding the counterclaim is mandatory, and not permissive,

and would be considered waived unless filed as a counterclaim in the suit, claim, action, litigation or proceeding instituted by the Holder against the Company. The Company agrees that any forum outside the Governing Jurisdiction is an inconvenient forum and that any suit, claim, action, litigation or proceeding brought by the Company against the Holder in any court outside the Governing Jurisdiction should be dismissed or transferred to a court located in the Governing Jurisdiction. Furthermore, the Company irrevocably and unconditionally agrees that it will not bring or commence any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Holder arising out of or based upon this Note or any matter relating to this Note, or any other Transaction Document, or any contemplated transaction, in any forum other than the courts of the State of New York sitting in New York County, and the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such suit, claim, action, litigation or proceeding may be heard and determined in such New York State Court or, to the fullest extent permitted by applicable law, in such federal court. The Company and the Holder agree that a final judgment in any such suit, claim, action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(d)The Company and the Holder irrevocably consent to the service of process out of any of the aforementioned courts in any such suit, claim, action, litigation or proceeding by e-mail or the mailing of copies thereof by registered or certified mail postage prepaid, to it at the e-mail address or physical address, as applicable, provided for notices in this Note, such service to become effective immediately after the date of such e-mail or mailing, as applicable. The Company and the Holder each irrevocably waive any defense it may have on the grounds of insufficient or improper service with respect to service of process effected in accordance with this Section 8(b)(iv).

(e)Nothing herein shall affect the right of the Holder to serve process in any other manner permitted by law or to commence legal proceedings or to otherwise proceed against the Company or any other Person in the Governing Jurisdiction or in any other jurisdiction.

(f)THE PARTIES MUTUALLY WAIVE ALL RIGHT TO TRIAL BY JURY OF ALL CLAIMS OF ANY KIND ARISING OUT OF OR BASED UPON THIS NOTE OR ANY MATTER RELATING TO THIS NOTE, OR ANY OTHER TRANSACTION DOCUMENT, OR ANY CONTEMPLATED TRANSACTION. THE PARTIES ACKNOWLEDGE THAT THIS IS A WAIVER OF A LEGAL RIGHT AND THAT THE PARTIES EACH MAKE THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER CONSULTATION WITH COUNSEL OF THEIR RESPECTIVE CHOICE. THE PARTIES AGREE THAT ALL SUCH CLAIMS SHALL BE TRIED BEFORE A JUDGE OF A COURT HAVING JURISDICTION, WITHOUT A JURY.

9.If the Company fails to strictly comply with the terms of this Note, then the Company shall reimburse the Holder promptly for all fees, costs and expenses, including, without limitation, attorneys’ fees and expenses incurred by the Holder in any action in connection with this Note, including, without limitation, those incurred: (i) during any workout, attempted workout, and/or in connection with the rendering of legal advice as to the Holder’s rights, remedies and obligations, (ii) collecting any sums which become due to the holder, (iii) defending or prosecuting any proceeding or any counterclaim to any proceeding or appeal; or (iv) the protection, preservation or enforcement of any rights or remedies of the Holder.

10.Any waiver by the Holder of a breach of any provision of this Note shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note. Any waiver must be in writing.

11.If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the Principal of or interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Note, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such power as though no such law has been enacted.

(c)The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, engage in any material line of business substantially different from those lines of business conducted by or publicly contemplated to be conducted by the Company and/or its Subsidiaries on the Closing Date or any business reasonably related or incidental thereto.

2.BUYER’S REPRESENTATIONS AND WARRANTIES.

The Buyer represents and warrants to the Company that as of the date hereof and as of the Closing Date:

(a)Investment Purpose. The Buyer is acquiring the Securities for its own account for investment purposes and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered under or exempt from the registration requirements of the Securities Act; provided, however, that by making the representations herein, the Buyer does not agree, or make any representation or warranty, to hold any of the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with, or pursuant to, a registration statement covering such Securities or an available exemption under the Securities Act. The Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of the Securities in violation of Applicable Securities Laws. As used herein,

“Person” means a corporation, a limited liability company, an association, a partnership, an organization, a business, an individual, governmental or political subdivision thereof or a governmental agency. As used herein, “Applicable Securities Laws” means (a) the applicable securities laws of each of the provinces and territories of Canada, their respective regulations, rulings, rules, orders (including blanket orders and discretionary orders), instruments (including national and multilateral instruments), fee schedules and prescribed forms thereunder, and the applicable policy statements issued by the applicable securities commissions or regulatory authority or similar authority thereunder (“Canadian Securities Laws”) and (b) all applicable securities laws in the United States, including, without limitation, the Securities Act, the Exchange Act and the rules and regulations promulgated thereunder, and any applicable state securities laws (“U.S. Securities Laws”).

(b)Accredited Investor Status. The Buyer is an “Accredited Investor” as that term is defined in Rule 501(a)(3) of Regulation D.

(c)Reliance on Exemptions. The Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from: (i) the registration requirements of U.S. Securities Laws; and (ii) the exemption from the prospectus requirements of the Securities Act (Ontario) under Section 2.3 of OSC Rule 72-503, and that, in each case, the Company is relying in part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the Securities.

(d)Information. The Buyer has been furnished with all materials relating to the business, finances and operations of the Company and information the Buyer deemed material to making an informed investment decision regarding its purchase of the Securities, which have been requested by the Buyer. The Buyer has been afforded the opportunity to ask questions of the Company and its management and has received answers to such questions. Neither such inquiries nor any other due diligence investigations conducted by the Buyer or its representatives shall modify, amend or affect the Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Buyer understands that its investment in the Securities involves a high degree of risk. The Buyer has sought such accounting, legal and tax advice, as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. The Buyer acknowledges and agrees that the Company does not make and has not made any representation or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.

(e)Transfer or Resale. The Buyer understands that: (i) the Securities have not been registered under U.S. Securities Laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) the Buyer shall have delivered to the Company an opinion of counsel, in a form generally acceptable to the Company and the Company’s transfer agent, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration requirements, (C) the Buyer provides the Company with reasonable assurances (in the form of seller and broker representation letters reasonably acceptable to the Company) that such Securities can be sold, assigned or transferred pursuant to Rule 144 promulgated under the Securities Act, as amended (or a successor rule thereto) (collectively, “Rule 144”), in each case following the applicable holding period set forth therein; or (D) the Buyer shall have delivered to the Company and the Company’s transfer agent and Rule 904 declaration in a form agreed to by the Company and the Company’s transfer agentand (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term

is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation, this Section 2(e). In addition, the Buyer understands that (i) the Securities have not been qualified for distribution by prospectus in any jurisdiction of Canada, and may not be offered for sale, sold, assigned or transferred in any jurisdiction of Canada during the course of the distribution thereof, except pursuant to a prospectus or exemption from the prospectus requirement under Canadian Securities Laws. The Buyer covenants and agrees that it shall not directly or indirectly, during the course of the distribution of the distribution of the Securities, make any offers or sales of securities in connection with this Agreement directly to any person whom, to the Buyer’s knowledge, is (A) a person resident or located in a jurisdiction of Canada; (B) a person acquiring such securities for the benefit of another person resident or located in a jurisdiction of Canada, or (C) on any “marketplace” (as such term is defined in National Instrument 21-101 – Marketplace Operation) in Canada. The Company and the Buyer shall take all further steps reasonably required to ensure compliance with the provisions of OSC Rule 72-503. For clarity, a distribution made on or through the facilities of an exchange or market outside Canada is a distribution to a person or company outside Canada if neither the seller nor any person acting on its behalf has reason to believe that the distribution has been pre-arranged with a buyer in Canada.

(f)Legends. The Buyer agrees to the imprinting, so long as its required by this Section 2(f), of a restrictive legend on the Securities in substantially the following form:

THE SECURITIES REPRESENTED HEREBY [for Convertible Note add: AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE] HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES AND THOSE SECURITIES INTO WHICH THEY ARE CONVERTIBLE HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TOWARD RESALE AND MAY ONLY BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS, (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN THE CASE OF SUBPARAGRAPH (C) OR (D), THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING OR SUCH OTHER EVIDENCE AS THE CORPORATION MAY REQUIRE IN FORM AND

SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.

Subject to the provision of representation letters from the Buyer and its representatives as the Company may require, certificates evidencing the Conversion Shares shall not contain any legend (including the legend set forth above), (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Conversion Shares pursuant to Rule 144, (iii) if such Conversion Shares are eligible for sale under Rule 144, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than one (1) Trading Days (as defined in the Convertible Note) (or such earlier date as required pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or other applicable law, rule or regulation for the settlement of a trade initiated on the date the Buyer delivers such legended certificate representing such securities to the Company) following the delivery by a Buyer to the Company or the transfer agent (with notice to the Company) of a legended certificate representing such securities (endorsed or with stock powers attached, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from the Buyer as may be required above in this Section 2(f), as directed by the Buyer, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated Securities Transfer Program, credit the aggregate number of shares of Common Shares to which the Buyer shall be entitled to the Buyer’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to the Buyer, a certificate representing such securities that is free from all restrictive and other legends, registered in the name of the Buyer or its designee. The Company shall be responsible for any transfer agent fees or DTC fees with respect to any issuance of Securities or the removal of any legends with respect to any Securities in accordance herewith. The Buyer agrees that the removal of a restrictive legend from certificates representing Securities as set forth in this Section 2(f) is predicated upon the Company’s reliance that the Buyer will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

(o)PCMLA. The Purchase Price which will be advanced by the Buyer to the Company hereunder will not represent proceeds of crime for the purposes of the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (Canada) (the “PCMLA”) and the Buyer acknowledges that the Company may in the future be required by law to disclose the Buyer’s name and other information relating to this Agreement and the Buyer’s subscription hereunder, on a confidential basis, pursuant to the PCMLA; and to the best of its knowledge (i) none of the subscription funds to be provided by the Buyer (A) have been or will be derived from or related to any activity that is deemed criminal under the laws of Canada, the United States of America, or any other jurisdiction, or (B) are being tendered on behalf of a person or entity who has not been identified to the Buyer, and (ii) it shall promptly notify the Company if the Buyer discovers that any of such representations ceases to be true, and to provide the Company with appropriate information in connection therewith.

The Company further represents to the Buyer that the Company’s decision to enter into the Transaction Documents to which it is a party has been based solely on the independent evaluation by the Company and its representatives.

(h)No Integrated Offering. None of the Company, its Subsidiaries or any of their affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to require approval of shareholders of the Company under any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated for quotation, other than as set forth herein. None of the Company, its Subsidiaries, their affiliates nor any Person acting on their behalf will take any action or steps that would cause the offering of any of the Securities to be integrated with other offerings of securities of the Company.

(i)Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares will increase in certain circumstances and could cause dilution to existing shareholders.

(j)Continuous Disclosure Materials; Financial Statements. During the two (2) years prior to the date hereof, and, as applicable, the Closing Date, the Company has timely filed, or will have timely filed, all reports, schedules, forms, proxy statements, statements and other documents required to be filed by it under Applicable Securities Laws (all of the foregoing filed prior to the date hereof and, as applicable, the Closing Date and all exhibits and appendices included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “Continuous Disclosure Materials”). The Company has delivered or has made available to the Buyer or its representatives true, correct and complete copies of each of the Continuous Disclosure Materials not available on the EDGAR system or SEDAR+ system. As of their respective dates, the Continuous Disclosure Materials complied in all material respects with the requirements of the Applicable Securities Laws applicable to the Continuous Disclosure Materials, and none of the

Continuous Disclosure Materials, at the time they were filed on the EDGAR system or SEDAR+ system (subject to amendments thereto), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the Continuous Disclosure Materials complied in all material respects with applicable accounting requirements and the Applicable Securities Laws with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IFRS”), consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year­end audit adjustments which will not be material, either individually or in the aggregate). The reserves, if any, established by the Company or the lack of reserves, if applicable, are reasonable based upon facts and circumstances known by the Company on the date hereof and there are no loss contingencies that are required to be accrued by the applicable financial accounting standards of the Financial Accounting Standards Board which are not provided for by the Company in its financial statements or otherwise. No other information provided by or on behalf of the Company to the Buyer which is not included in the Continuous Disclosure Materials contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstance under which they are or were made, not misleading. The Company is not currently contemplating to further amend or restate any of the financial statements (including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included in the Continuous Disclosure Materials (the “Financial Statements”), nor is the Company currently aware of facts or circumstances which would require the Company to further amend or restate any of the Financial Statements, in each case, in order for any of the Financial Statements to be in compliance with IFRS and the rules and regulations of the SEC. The Company has not been informed by its independent accountants that they recommend that the Company amend or restate any of the Financial Statements or that there is any need for the Company to amend or restate any of the Financial Statements.

(k)Absence of Certain Changes. Since the date of the Company’s most recent audited financial statements that are available on the SEC’s website through the EDGAR system or through the SEDAR+ system (the “Prior Annual Financial Statements”), there has been no Material Adverse Effect, nor any event or occurrence specifically affecting the Company or its Subsidiaries that would be reasonably expected to result in a Material Adverse Effect. Since the date of the Prior Annual Financial Statements, neither the Company nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any material assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any material capital expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company or any Subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so.

(l)No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or exists, or is reasonably expected to exist or occur specific to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition

(financial or otherwise), that has not been publicly disclosed and would reasonably be expected to have a Material Adverse Effect.

Neither the Company nor any of its Subsidiaries is in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company nor any of its Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for violations which would not reasonably be expected to have a Material Adverse Effect. Without limiting the generality of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of Principal U.S. Market or Cboe and has no knowledge of any facts or circumstances that could reasonably lead to delisting or suspension of the Common Shares by Principal U.S. Market or Cboe in the foreseeable future. During the one year prior to the date hereof, (i) the Common Shares have been listed or designated for quotation on Principal U.S. Market and Cboe, (ii) trading in the Common Shares has not been suspended by Principal U.S. Market or Cboe, and (iii) the Company has received no communication, written or oral, from Principal U.S. Market or Cboe regarding the suspension or delisting of the Common Shares from Principal U.S. Market or Cboe, which has not been publicly disclosed.

There is no agreement, commitment, judgment, injunction, order or decree binding upon the Company or any of its Subsidiaries or to which the Company or any of its Subsidiaries is a party which has or would reasonably be expected to have the effect of prohibiting or materially impairing any business practice of the Company or any of its Subsidiaries, any acquisition of property by the Company or any of its Subsidiaries or the conduct of business by the Company or any of its Subsidiaries as currently conducted other than such effects, individually or in the aggregate, which have not had and would not reasonably be expected to have a Material Adverse Effect on the Company or any of its Subsidiaries.

(n)Foreign Corrupt Practices. Except as, individually or in the aggregate, would not reasonably be expected to be material to the Company and the Subsidiaries, taken as a whole, since January 1, 2021, none of the Company or the Subsidiaries, nor any director, manager, officer, employee, or, to the actual knowledge of the Company, agent or representative of the Company or any of the Subsidiaries, has directly or indirectly through another person made, offered to make, attempted to make, or accepted any contribution, gift, bribe, rebate, payoff, influence payment, kickback or other payment to or from any person, private or public, regardless of what form, whether in money, property or services, in violation of the U.S. Foreign Corrupt Practices Act of 1977, as amended, the Corruption of Foreign Public Officials Act (Canada), as amended, and any foreign or other anti-bribery or anti-corruption laws (collectively, “Anti-Corruption Laws”). Since January 1, 2021, none of the Company or any of the Subsidiaries, or any of their respective directors, officers, employees or representatives has been under internal or, to the actual knowledge of the Company, any federal, state, provincial, local, foreign or supranational government, any court, legislative, administrative, regulatory or other governmental agency, commission or authority or any non-governmental self-regulatory agency, commission or authority or any stock exchange (each, a “Governmental Entity”) investigation for any material violation of any Anti-Corruption Laws or has received any written notice or other communication from any Governmental Entity regarding a violation of, or failure to

comply with, any Anti-Corruption Laws. Since January 1, 2021, the Company and the Subsidiaries have implemented, maintained and enforced an adequate system or systems of internal controls reasonably designed to ensure compliance with the Anti-Corruption Laws and prevent and detect violations of the Anti-Corruption Laws. Since January 1, 2021, neither the Company nor any of the Subsidiaries has made any disclosure (voluntary or otherwise) to any Governmental Entity with respect to any alleged irregularity, misstatement or omission or other potential violation or liability arising under or relating to any Anti-Corruption Laws.

(o)Equity Capitalization. As of the date hereof, the authorized capital of the Company consists of an unlimited number of Common Shares and an unlimited number of preferred shares.

The Common Shares are registered pursuant to Section 12(b) of the Exchange Act and are listed on a Principal U.S. Market. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Shares under the Exchange Act, delisting the Common Shares from the Principal U.S. Market, nor has the Company received any notification that the SEC or the Principal U.S. Market is contemplating terminating such registration or listing. To the Company’s knowledge, it is in compliance with all applicable listing requirements of the Principal U.S. Market. For the purposes of this Agreement, “Principal U.S. Market” shall mean the NYSE American; provided however, that in the event the Common Shares are ever listed or traded on the New York Stock Exchange, or the Nasdaq Stock Market, then the “Principal U.S. Market” shall mean such other market or exchange on which the Common Shares are then listed or traded to the extent such other market or exchange is the principal trading market or exchange for the Common Shares in the United States.

Company. None of the disclosures provided to the Buyer regarding the Company and its Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Agreement (if any), furnished by or on behalf of the Company or any of its Subsidiaries, taken as a whole, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

(iv)The Company and the Buyer irrevocably consent to the service of process out of any of the aforementioned courts in any such suit, claim, action, litigation or proceeding by the mailing of copies thereof by registered or certified mail postage prepaid, to it at the address provided for notices in

(i)In consideration of the Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Buyer and all of their shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Buyer Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and reasonable and documented expenses in connection therewith (irrespective of whether any the Buyer Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Buyer Indemnitee as a result of, or arising out of, or relating to (i) any material misrepresentation or material breach of any representation or warranty made by the Company in any of the Transaction Documents, or (ii) any material breach of any material covenant, material agreement or material obligation of the Company or any Subsidiary contained in any of the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(ii)In consideration of the Company’s execution and delivery of the Transaction Documents and in addition to the Buyer’s obligations under the Transaction Documents, the Buyer shall defend, protect, indemnify and hold harmless the Company and its shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Company Indemnitees”) from and against any and all Indemnified Liabilities, incurred by any Company Indemnitees as a result of, or arising out of, or relating to (i) any misrepresentation or breach of any representation or warranty made by the Buyer in any of the Transaction Documents, or (ii) any material breach of any material covenant, material agreement or material obligation of the Buyer contained in any of the Transaction Documents. To the extent that

the foregoing undertaking by the Buyer may be unenforceable for any reason, the Buyer shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

(iii)Promptly after receipt by a Buyer Indemnitee or Company Indemnitee under this Section 9(i) of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, the Buyer Indemnitee or Company Indemnitee shall, if a claim in respect thereof is to be made against the Company or a Buyer under this Section 9(i), deliver to the Company or Buyer, as applicable, a written notice of the commencement thereof, and the Company or Buyer shall have the right to participate in, and, to the extent the Company or Buyer, as applicable so desires, to assume control of the defense thereof with counsel mutually reasonably satisfactory to the Company or Buyer and the Buyer Indemnitee or Company Indemnitee, as applicable; provided, however, that a Buyer Indemnitee or Company Indemnitee shall have the right to retain its own counsel with the actual and reasonable fees and expenses of such counsel to be paid by the Company or Buyer, if applicable, if: (A) the Company or Buyer has agreed in writing to pay such fees and expenses; (B) the Company or Buyer shall have failed promptly to assume the defense of such Indemnified Liability and to employ counsel reasonably satisfactory to the Buyer Indemnitee or Company Indemnitee in any such Indemnified Liability; or (C) the named parties to any such Indemnified Liability (including any impleaded parties) include both the Buyer Indemnitee or Company Indemnitee and the Company or Buyer, as applicable, and the Buyer Indemnitee or Company Indemnitee shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnitee and the Company or the Buyer, as applicable (in which case, if the Buyer Indemnitee or Company Indemnitee notifies the Company or Buyer, as applicable, in writing that it elects to employ separate counsel at the expense of the Company or Buyer, as applicable, then the Company or Buyer, as applicable, shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Company or Buyer, as applicable), provided further, that in the case of clause (C) above the Company or Buyer shall not be responsible for the reasonable fees and expenses of more than one separate legal counsel for the Indemnitees. The Buyer Indemnitee or Company Indemnitee shall reasonably cooperate with the Company or Buyer, as applicable, in connection with any negotiation or defense of any such action or Indemnified Liability by the Company or Buyer and shall furnish to the Company or Buyer all information reasonably available to the Indemnitee which relates to such action or Indemnified Liability. The Company or Buyer shall keep the Buyer Indemnitee or Company Indemnitee reasonably apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company or Buyer shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the Company or Buyer shall not unreasonably withhold, delay or condition its consent. The Company or Buyer, as applicable, shall not, without the prior written consent of the Buyer Indemnitee or Company Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the

claimant or plaintiff to the Buyer Indemnitee or Company Indemnitee of a release from all liability in respect to such Indemnified Liability or litigation, and such settlement shall not include any admission as to fault on the part of the Buyer Indemnitee or Company Indemnitee. Following indemnification as provided for hereunder, the Company or Buyer, as applicable, shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the Company or Buyer, as applicable, within a reasonable time of the commencement of any such action shall not relieve the Company or Buyer, as applicable, of any liability to the Buyer Indemnitee or Company Indemnitee under this Section 9(i), except to the extent that the Company or Buyer, as applicable, is materially and adversely prejudiced in its ability to defend such action.

(iv)The indemnification required by this Section 9(i) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within 10 days after bills supporting the Indemnified Liabilities are received by the Company or the Buyer, as applicable.

(v)The indemnity agreement contained herein shall be in addition to (A) any cause of action or similar right of the Buyer Indemnitee or Company Indemnitee against the Company or Buyer, as applicable, or others, and (B) any liabilities the Company or Buyer may be subject to pursuant to applicable law.

(l)No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m)Currency. Unless otherwise specified, all references to “$” or “dollars” in this Agreement means the lawful currency of the United States of America.

Certain capitalized terms used herein are defined in Section 14 and the Purchase Agreement.

1.GENERAL TERMS

(a)Maturity Date. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal and any other amounts outstanding pursuant to the terms of this Note, if any. The “Maturity Date” shall be June 30, 2027. Other than as specifically permitted by this Note, the Company may not prepay or redeem any portion of the outstanding Principal.

(b)Pre-Paid Interest. The Company shall pay to the Holder on the Issuance Date the Pre-Paid Interest Amount.

(c)Default Interest. Upon the occurrence of an Event of Default (defined below), interest shall accrue on the outstanding Principal balance at an annual rate of 18% (“Default Interest”), from and including the date of such Event of Default and to the date such Event of Default is cured and all outstanding Default Interest is paid. Default Interest shall be calculated based on a 360-day year and the actual number of days elapsed, to the extent permitted by applicable law and will be payable in arrears on the earlier of (i) the first day of each calendar month, (ii) the date such Event of Default is cured, and (iii) the date on which any portion of the outstanding Principal of this Note is reduced or otherwise retired.

If, any time after the Issuance Date set forth above, and from time to time thereafter, an Amortization Event has occurred, then the Company shall make monthly cash payments beginning on the fourteenth Trading Day after the Amortization Event Date and continuing on the same day of each successive calendar month (each, an “Amortization Event Payment Date”) until the entire outstanding amounts shall have been repaid. Each monthly cash payment shall be in an amount equal to the sum of (i) the Amortization Principal Amount, plus (ii) the applicable Payment Premium in respect of such Amortization Principal Amount (the “Amortization Amount”). The obligation of the Company to make monthly cash payments related to an Amortization Event shall cease (with respect to any payment that has not yet come due) if at any time after the Amortization Event Date, the condition or event causing the Amortization Event has been cured or the Holder is able to resell the Common Shares issuable upon conversion of this Note in accordance with Rule 144 under the Securities Act, unless a subsequent Amortization Event occurs. Notwithstanding any provision of this Section 1(d) to the contrary, the Holder may, at its option and in its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable Amortization Event Payment Date electing to have the payment of all or any portion of such Amortization Amount payable on such Amortization Event Payment Date deferred to the next subsequent Amortization Event Payment Date.

(e)Optional Prepayment. So long as no Event of Default has occurred and is continuing (or, after notice, passage of time or both, would be an Event of Default), the Company at its option shall have the right, but not the obligation, to prepay (“Optional

Prepayment”) early a portion or all amounts outstanding under this Note as described in this Section; provided, that the Company provides the Holder with written notice (each, a “Prepayment Notice”) of its desire to exercise an Optional Prepayment, which Prepayment Notice shall be delivered to the Holder after the close of regular trading hours on a Trading Day. Each Prepayment Notice shall be irrevocable and shall specify the outstanding balance of the Note to be prepaid and the Prepayment Amount. The “Prepayment Amount” shall be an amount equal to (a) the outstanding Principal balance being prepaid by the Company plus (b) the applicable Payment Premium in respect of such Principal amount. After receipt of a Prepayment Notice, the Holder shall have ten Trading Days (beginning with the Trading Day immediately following the date such Prepayment Notice is delivered to the Holder in accordance with this term of this Section 1(e) to elect to convert all or any portion of this Note. On the eleventh Trading Day following the delivery of the applicable Prepayment Notice, the Company shall deliver to the Holder the Prepayment Amount with respect to the Principal amount redeemed to the extent not converted and otherwise after giving effect to conversions or other payments made during such ten Trading Day period.

(f)Other than as specifically set forth in this Note, the Company shall not have the ability to make any early repayments without the consent of or at the request of the Holder.

(g)Payment Dates. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

(h)Withholding Tax. All amounts paid or credited or deemed to have been paid or credited by or on behalf of the Company under or with respect to this Note or any other Transaction Document (including, without limitation, any penalties, interest and other liabilities related thereto) will be made free and clear of and without withholding, or deduction for, or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other liabilities related hereto) imposed or levied by or on behalf of the Government of Canada or elsewhere, or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Withholding Taxes”), unless the Company is required by law or the interpretation or administration thereof, to withhold or deduct any amounts for, or on account of Withholding Taxes. If the Company determines, in its sole and absolute discretion, that it is so required to withhold or deduct any amount for, or on account of, Withholding Taxes from any amount paid or credited or deemed to have been be paid or credited under or with respect to this Note or any other Transaction Document, the Company shall deduct and withhold such Withholding Taxes from any amount paid or credited or deemed to have been paid or credited under or with respect to this Note or any other Transaction Document and, provided that the Company forthwith remits such amount to the relevant governmental authority or agency, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Company’s obligations under this Note or any other Transaction Document. There is no obligation on the Company to gross-up or pay any additional amounts to any holder of this Note or to any party under any other Transaction Document in respect of such deductions or withholdings. For greater certainty, if any amount is required to be deducted or withheld in respect of Withholding Taxes upon a conversion of this Note, the Company shall be entitled to liquidate (whether directly or through a broker) such number of Common Shares (or other securities) otherwise issuable as a result of such conversion as shall be necessary in order to satisfy such requirement plus any broker or other fees associated with such liquidation. The Company shall provide the applicable holder of this Note with

copies of receipts or other communications relating to the remittance of such withheld amount or the filing of any forms received from such government authority or agency promptly after receipt thereof.  Each holder of this Note and each relevant party shall indemnify and hold the Company harmless from any loss, interest, penalties, tax or other amounts for which the Company may be liable for any failure to deduct, withhold or remit Withholding Taxes in connection with any amount paid or credited or deemed to have been paid or credited under this Note or any other Transaction Document.

other remedies available to it under applicable law. Such declaration may be rescinded and annulled by the Holder in writing at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

3.CONVERSION OF NOTE.    This Note shall be convertible into Common Shares, on the terms and conditions set forth in this Section 3.

(a)Conversion Right. Subject to the limitations of Section 3(c), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and non-assessable Common Shares in accordance with Section 3(b), at the Conversion Price. The number of Common Shares issuable upon conversion of any Conversion Amount pursuant to this Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price. The Company shall not issue any fraction of a Common Shares upon any conversion. All calculations under this Section 4 shall be rounded to the nearest $0.0001. If the issuance would result in the issuance of a fraction of a Common Share, the Company shall round such fraction of a Common Share down to the nearest whole Common Share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Shares upon conversion of any Conversion Amount, unless such taxes are due because the Holder requests such Common Shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay such taxes.

(b)Mechanics of Conversion.

(a)Optional Conversion. To convert any Conversion Amount into Common Shares on any date (a “Conversion Date”), the Holder shall (A) transmit by email (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and (B) if required by Section 3(b)(iii), surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Note in the case of its loss, theft or destruction). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) if legends are not required to be placed on certificates or the book-entry position of the Common Shares and provided that the Company’s transfer agent is participating in the Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program, instruct such transfer agent to credit such aggregate number of Common Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate or book-entry position, registered in the name of the Holder or its designee, for the number of Common Shares to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant to rules and regulations of the Commission. If this Note is physically surrendered for conversion and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note representing the outstanding Principal not converted. The Person or Persons entitled to receive the Common Shares issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such Common Shares

upon the transmission of a Conversion Notice; provided, that the Holder shall be deemed to have waived any voting rights of any such Conversion Shares that may arise during the period commencing on such Conversion Date, through, and including, such applicable Share Delivery Deadline, as necessary, such that the aggregate voting rights of any Common Shares (including such Conversion Shares) beneficially owned by the Holder and/or any Attribution Parties, collectively, shall not exceed the Beneficial Ownership Limitation (as defined below) as a result of any such conversion of this Note.

(b)Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable Share Delivery Date to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of Common Shares to which the Holder is entitled upon such Holder’s conversion of any Conversion Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Common Shares issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the Common Shares so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Shares to which the Holder is entitled with respect to such Conversion Notice and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Common Shares, multiplied by (B) the Closing Price on the Conversion Date.

(c)Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon any conversion.

(d)Limitations on Conversions.

(a)Beneficial Ownership. The Company shall not effect any conversion of this Note, and a Holder shall not have the right to convert any portion of this Note, to the extent that after giving effect to the conversion set forth on the applicable notice of conversion, the Holder (together with the Holder’s affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder and its affiliates and Attribution Parties shall include the number of Common Shares issuable upon conversion of this Note with respect to which such determination is being made, but shall exclude the number of Common Shares which would be issuable upon (i) conversion of the remaining, unconverted principal amount of this Note (plus, if applicable, any accrued and unpaid interest thereon) beneficially owned by the Holder or any of its affiliates or Attribution

(b)Other Provisions.

(a)All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.

(b)Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company’s failure to deliver certificates representing Common Shares upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(c)Legal Opinions. The Company is obligated to cause its legal counsel to deliver legal opinions to the Company’s transfer agent in connection with any legend removal upon the expiration of any holding period or other requirement for which the Underlying Shares may bear legends restricting the transfer thereof. To the extent a legal opinion is not provided (either timely or at all), then, in addition to being an Event of Default hereunder, the Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with the sale or transfer of the Underlying Shares. The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

(d)Adjustment of Conversion Price upon Subdivision or Combination of Common Shares. If the Company, at any time while this Note is outstanding, shall (i) pay a stock dividend or otherwise make a distribution or distributions on its Common Shares or any other equity or equity equivalent securities payable in Common Shares, (ii) subdivide outstanding Common Shares into a larger number of shares, (iii) combine (including by way of reverse stock split) outstanding Common Shares into a smaller number of shares, or (iv) issue by reclassification of Common Shares any shares of capital stock of the Company, then the Fixed Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of Common Shares outstanding after such event. Any adjustment made pursuant to this Section shall become effective, in the case of a dividend distribution, immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution or, in the case of a subdivision, combination or re-classification, and shall become effective immediately after the effective date of such subdivision, combination or re-classification.

(e)Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option, (i) in addition to the Common Shares receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such Common Shares had such Common Shares been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the Common Shares otherwise receivable upon such conversion, such securities or other assets received by the holders of Common Shares in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to Common Shares) at a conversion rate for such consideration commensurate with the Conversion Price. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or prepayment of this Note.

(f)Whenever the Conversion Price is adjusted pursuant to this Section 3, the Company shall promptly provide the Holder with a written notice setting forth the

Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(g)In case of any (1) merger or consolidation of the Company or any Subsidiary of the Company with or into another Person, or (2) sale by the Company or any Subsidiary of the Company of more than one-half of the assets of the Company in one or a series of related transactions, a Holder shall have the right to (A) exercise any rights under Section 3(f), (B) convert the aggregate amount of this Note then outstanding into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Shares following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the Common Shares into which such aggregate Principal amount of this Note could have been converted immediately prior to such merger, consolidation or sales would have been entitled, or (C) in the case of a merger or consolidation, require the surviving entity to issue to the Holder a convertible Note with a Principal amount equal to the aggregate Principal amount of this Note then held by such Holder, plus all other amounts owing thereon, which such newly issued convertible Note shall have terms identical (including with respect to conversion) to the terms of this Note, and shall be entitled to all of the rights and privileges of the Holder of this Note set forth herein and the agreements pursuant to which this Note was issued. In the case of clause (C), the conversion price applicable for the newly issued convertible debentures or convertible Notes shall be based upon the amount of securities, cash and property that each Common Share would receive in such transaction and the Conversion Price in effect immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger, sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or prepayment following such event. This provision shall similarly apply to successive such events.

4.REISSUANCE OF THIS NOTE.

(a)Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 4(d)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder and, if less than the entire outstanding Principal is being transferred, a new Note (in accordance with Section 4(d)) to the Holder representing the outstanding Principal not being transferred.

8.CHOICE OF LAW; VENUE; WAIVER OF JURY TRIAL

(a)Governing Law. This Note and the rights and obligations of the Parties hereunder shall, in all respects, be governed by, and construed in accordance with, the laws (excluding the principles of conflict of laws) of the State of New York (the “Governing Jurisdiction”) (including Section 5-1401 and Section 5-1402 of the General Obligations Law of the State of New York), including all matters of construction, validity and performance.

(b)Jurisdiction; Venue; Service.

(a)The Company hereby irrevocably consents to the non-exclusive personal jurisdiction of the state courts of the Governing Jurisdiction and, if a basis for federal jurisdiction exists, the non-exclusive personal jurisdiction of any United States District Court for the Governing Jurisdiction.

(b)The Company agrees that venue shall be proper in any court of the Governing Jurisdiction selected by the Holder or, if a basis for federal jurisdiction exists, in any United States District Court in the Governing Jurisdiction selected by the Holder. The Company waives any right to object to the maintenance of any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, in any of the state or federal courts of the Governing Jurisdiction on the basis of improper venue or inconvenience of forum.

(c)Any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or tort or otherwise, brought by the Company against the Holder arising out of or based upon this Note or any matter relating to this Note, or any other Transaction Document, or any contemplated transaction, shall be brought in a court only in the Governing Jurisdiction. The Company shall not file any counterclaim against the Holder in any suit, claim, action, litigation or proceeding brought by the Holder against the Company in a jurisdiction outside of the Governing Jurisdiction unless under the rules of the court in which the Holder brought such suit, claim, action, litigation or proceeding the counterclaim is mandatory, and not permissive,

and would be considered waived unless filed as a counterclaim in the suit, claim, action, litigation or proceeding instituted by the Holder against the Company. The Company agrees that any forum outside the Governing Jurisdiction is an inconvenient forum and that any suit, claim, action, litigation or proceeding brought by the Company against the Holder in any court outside the Governing Jurisdiction should be dismissed or transferred to a court located in the Governing Jurisdiction. Furthermore, the Company irrevocably and unconditionally agrees that it will not bring or commence any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Holder arising out of or based upon this Note or any matter relating to this Note, or any other Transaction Document, or any contemplated transaction, in any forum other than the courts of the State of New York sitting in New York County, and the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such suit, claim, action, litigation or proceeding may be heard and determined in such New York State Court or, to the fullest extent permitted by applicable law, in such federal court. The Company and the Holder agree that a final judgment in any such suit, claim, action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(d)The Company and the Holder irrevocably consent to the service of process out of any of the aforementioned courts in any such suit, claim, action, litigation or proceeding by e-mail or the mailing of copies thereof by registered or certified mail postage prepaid, to it at the e-mail address or physical address, as applicable, provided for notices in this Note, such service to become effective immediately after the date of such e-mail or mailing, as applicable. The Company and the Holder each irrevocably waive any defense it may have on the grounds of insufficient or improper service with respect to service of process effected in accordance with this Section 8(b)(iv).

(e)Nothing herein shall affect the right of the Holder to serve process in any other manner permitted by law or to commence legal proceedings or to otherwise proceed against the Company or any other Person in the Governing Jurisdiction or in any other jurisdiction.

(f)THE PARTIES MUTUALLY WAIVE ALL RIGHT TO TRIAL BY JURY OF ALL CLAIMS OF ANY KIND ARISING OUT OF OR BASED UPON THIS NOTE OR ANY MATTER RELATING TO THIS NOTE, OR ANY OTHER TRANSACTION DOCUMENT, OR ANY CONTEMPLATED TRANSACTION. THE PARTIES ACKNOWLEDGE THAT THIS IS A WAIVER OF A LEGAL RIGHT AND THAT THE PARTIES EACH MAKE THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER CONSULTATION WITH COUNSEL OF THEIR RESPECTIVE CHOICE. THE PARTIES AGREE THAT ALL SUCH CLAIMS SHALL BE TRIED BEFORE A JUDGE OF A COURT HAVING JURISDICTION, WITHOUT A JURY.

9.If the Company fails to strictly comply with the terms of this Note, then the Company shall reimburse the Holder promptly for all fees, costs and expenses, including, without limitation, attorneys’ fees and expenses incurred by the Holder in any action in connection with this Note, including, without limitation, those incurred: (i) during any workout, attempted workout, and/or in connection with the rendering of legal advice as to the Holder’s rights, remedies and obligations, (ii) collecting any sums which become due to the holder, (iii) defending or prosecuting any proceeding or any counterclaim to any proceeding or appeal; or (iv) the protection, preservation or enforcement of any rights or remedies of the Holder.

10.Any waiver by the Holder of a breach of any provision of this Note shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note. Any waiver must be in writing.

11.If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the Principal of or interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Note, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such power as though no such law has been enacted.
