outstanding equity of such Subsidiary and is its sole general partner. The Company’s Subsidiary is duly organized and validly existing and in good standing under the laws of its jurisdiction of incorporation and has all requisite power and
authority to carry on its business as now conducted. The Company’s Subsidiary is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which the conduct of its business or its ownership or

	 	2.2	 Authorization. The Company has the requisite corporate power and authority and has taken all
requisite corporate action necessary for, and no further action on the part of the Company, its officers, directors and

Documents by the Company and the issuance and sale of the Shares in accordance with the provisions hereof will not, except (solely in the case of clauses (i)(b) and (ii)) for such violations, conflicts or defaults as would not reasonably be
expected, individually or in the aggregate, to have a Material Adverse Effect, (i) conflict with or result in a breach or violation of (a) any of the terms and provisions of, or constitute a default under, the Company’s Certificate of

Knowledge, threatened action, suit, proceeding or claim by any Person that the Company’s business or the business of its Subsidiary as now conducted infringes or violates any patent, trademark, copyright, trade secret or other intellectual
property rights of another. To the Company’s Knowledge, there is no existing infringement by another Person of any of the Intellectual Property owned or exclusively licensed by the Company or its Subsidiary that would have or would
reasonably be expected to have a Material Adverse Effect. The Company and its Subsidiary have taken reasonable security measures to protect the secrecy, confidentiality and value of the non-public portions of
the Intellectual Property owned or exclusively licensed by the Company or its Subsidiary, except where failure to do so would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

controls and all applicable laws; the descriptions of the results of such studies, tests and trials contained in the SEC Filings are accurate and complete and fairly present the data derived from such studies, tests and trials in all material
respects as of the respective dates of such SEC Filings; the Company is not aware of any studies, tests or trials, the results of which the Company believes are materially inconsistent with the study, test or trial results described or referred to
in the SEC Filings when viewed in the context in which such results are described and the clinical state of development; and the Company has not received any notices or written correspondence from the U.S. Food and Drug Administration or any other
federal, state, local or foreign governmental or regulatory authority requiring the

reasonably be expected to materially affect, the Company’s internal control over financial reporting. 


  

	 	2.28	 Manipulation of Price. The Company has not taken, nor will it take, directly or indirectly any action
designed to stabilize or manipulate the price of the Common Stock or any security of the Company to facilitate the sale or resale of any of the Shares. 


  

	 	2.29	 No Bad Actors. No “bad actor” disqualifying event described in Rule 506(d)(1)(i)-(viii) of

 12 














	 	 
Company Covered Person, except for a Disqualification Event as to which Rule 506(d)(2)(ii–iv) or (d)(3) is applicable.

	 	Section 3.	 Representations and Warranties of the Investor. The Investor hereby represents and
warrants to the Company that: 


  

	 	3.1	 Organization. The Investor is a duly organized and validly existing legal entity and has all
requisite corporate, partnership, limited liability company or similar power and authority, as applicable, to enter into and consummate the transactions contemplated by the Transaction Documents, to carry out its obligations hereunder and
thereunder, and to invest in the Shares pursuant to this Agreement, and is in good standing under the laws of the jurisdiction of its organization. 


  

	 	3.2	 Authorization. The execution, delivery and performance by the Investor of the Transaction Documents
have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of the Investor, and each has been duly executed and when delivered will constitute the valid and legally
binding obligation of the Investor, enforceable against the Investor in accordance with their respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability, relating to
or affecting creditors’ rights generally, and general principles of equity. 


  

	 	3.3	 Purchase Entirely for Own Account. The Shares to be received by the Investor hereunder will be
acquired for the Investor’s own account, not as nominee or agent, for the purpose of investment and not with a view to the resale or distribution of any part thereof in violation of the 1933 Act, and the Investor has no present intention of
selling, granting any participation in, or otherwise distributing the same in violation of the 1933 Act without prejudice, however, to the Investor’s right at all times to sell or otherwise dispose of all or any part of such Shares in
compliance with applicable federal and state securities laws. Nothing contained herein shall be deemed a representation or warranty by the Investor to hold the Shares for any period of time. The Investor is not a broker-dealer registered with the
SEC under the 1934 Act or an entity engaged in a business that would require it to be so registered. 


  

	 	3.4	 Investment Experience. The Investor acknowledges that it can bear the economic risk and complete loss
of its investment in the Shares and has such knowledge and experience in financial or business matters that it is 



  
 13 














	 	 
capable of evaluating the merits and risks of the investment contemplated hereby. 


  

	 	3.5	 Disclosure of Information. The Investor has had an opportunity to receive, review and understand all
information related to the Company requested by it and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the offering of the Shares, and has conducted and completed its own
independent due diligence. The Investor acknowledges that copies of the SEC Filings are available on the EDGAR system. Based on the information the Investor has deemed appropriate, it has independently made its own analysis and decision to enter
into the Transaction Documents. The Investor is relying exclusively on its own investment analysis and due diligence (including professional advice it deems appropriate) with respect to the execution, delivery and performance of the Transaction
Documents, the Shares and the business, condition (financial and otherwise), management, operations, properties and prospects of the Company, including but not limited to all business, legal, regulatory, accounting, credit and tax matters. Neither
such inquiries nor any other due diligence investigation conducted by the Investor shall modify, limit or otherwise affect the Investor’s right to rely on the Company’s representations and warranties contained in this Agreement.



  

	 	3.6	 Restricted Securities. The Investor understands that the Shares are characterized as “restricted
securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without
registration under the 1933 Act only in certain limited circumstances. 


  

	 	3.7	 Legends. It is understood that, except as provided below, certificates evidencing the Shares (or
uncertificated interests in the Shares) may bear the following or any similar legend: 


 (a) “THE
SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.” 

(b) If required by the authorities of any state in connection with the issuance of sale of the Shares, the legend required by
such state authority. 

  
 14 














	 	3.8	 Accredited Investor. The Investor is (a) an “accredited investor” within the meaning
of Rule 501(a) of Regulation D. The Investor has executed and delivered to the Company a questionnaire in substantially the form attached hereto as Exhibit B (the “Investor Questionnaire”), which the Investor represents and
warrants is true, correct and complete. The Investor is a sophisticated institutional investor with sufficient knowledge and experience in investing in private equity transactions to properly evaluate the risks and merits of its purchase of the
Shares. 


  

	 	3.9	 No General Solicitation. The Investor did not learn of the investment in the Shares as a result of
any general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (a) any advertisement, article, notice or other communication published in any newspaper, magazine, website, or
similar media, or broadcast over television or radio, or (b) any seminar or meeting to which the Investor was invited by any of the foregoing means of communications. 



 

	 	3.10	 Brokers and Finders. No Person will have, as a result of the transactions contemplated by the
Transaction Documents, any valid right, interest or claim against or upon the Company or the Investor for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Investor.



  

	 	3.11	 Short Sales and Confidentiality Prior to the Date Hereof. Other than consummating the transactions
contemplated hereunder, the Investor has not, nor has any Person acting on behalf of or pursuant to any understanding with the Investor, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the
Company during the period commencing as of the time that the Investor was first contacted by the Company or any other Person regarding the transactions contemplated hereby and ending immediately prior to the date hereof. The Investor, its
Affiliates and authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents have maintained the confidentiality of all disclosures made to the Investor in connection with the transactions
contemplated by the Transaction Documents (including the existence and terms of such transactions). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any
actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 



 

	 	3.12	 No Government Recommendation or Approval. The Investor understands that no United States federal or
state agency, or similar agency of any other country, has reviewed, approved, passed upon, or 



  
 15 














	 	 
made any recommendation or endorsement of the Company or the purchase of the Shares. 


  

	 	3.13	 No Conflicts. The execution, delivery and performance by the Investor of the Transaction Documents
and the consummation by the Investor of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of the Investor or (ii) conflict with, or constitute a default (or an event which
with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Investor is a party, or
(iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to the Investor, except in the case of clauses (ii) and (iii) above, for such conflicts,
defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Investor to perform its obligations hereunder. 



 

	 	3.14	 Residency. The Investor’s office in which its investment decision with respect to the Shares was
made is located in Toronto, Ontario, Canada. 


  

	 	3.15	 Financial Capability. The Investor has immediately available funds necessary to consummate the
Closing on the terms and conditions contemplated by this Agreement. 


  

	 	Section 4.	 Covenants. 



 

	 	4.1	 Legend Removal.  



(a) In connection with any sale, assignment, transfer or other disposition of the Shares by the Investor pursuant to
Rule 144 or pursuant to any other exemption under the 1933 Act such that the purchaser acquires freely tradable shares and upon compliance by the Investor with the requirements of this Agreement, if requested by the Investor, the Company shall
cause the Transfer Agent to remove any restrictive legends related to the book-entry account holding such Shares and make a new, unlegended book entry for such Shares sold or disposed of without restrictive legends within two Trading Days of any
such request therefor from the Investor, provided that the Company has timely received from the Investor customary representations and other documentation reasonably acceptable to the Company in connection therewith. 

(b) Subject to receipt from the Investor by the Company and the Transfer Agent of customary representations and other
documentation reasonably acceptable to the Company and the Transfer Agent in connection therewith, upon the earliest of such time as the Shares (i) have been sold or transferred pursuant to an effective registration statement, (ii) have
been sold pursuant to Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor provision, the Company shall, in accordance with the provisions of this Section 4.1(b) and within
three Trading Days of any request therefor from the Investor accompanied by such customary and reasonably acceptable documentation referred to above, (A) deliver to the Transfer Agent 

  
 16 













 
irrevocable instructions that the Transfer Agent shall make a new, unlegended book entry for such Shares, (B) cause its counsel to deliver to the Transfer Agent one or more opinions to the
effect that the removal of such legends in such circumstances may be effected under the 1933 Act if required by the Transfer Agent to effect the removal of the legend, and (C) deliver or cause to be delivered to the Investor a new, unlegended
book-entry notation or other evidence that the legend has been removed. 
 (c) The Investor agrees with the Company
(i) that the Investor will sell any Shares pursuant to either the registration requirements of the 1933 Act, including any applicable prospectus delivery requirements, or an exemption therefrom, (ii) that if Shares are sold pursuant to a
registration statement, they will be sold in compliance with the plan of distribution set forth therein and (iii) that if, after the effective date of the registration statement covering the resale of the Shares, such registration statement is
not then effective and the Company has provided notice to the Investor to that effect, the Investor will sell Shares only in compliance with an exemption from the registration requirements of the 1933 Act. 

 

	 	4.2	 Short Sales and Confidentiality After the Date Hereof. The Investor covenants that neither it nor any
Affiliates acting on its behalf or pursuant to any understanding with it will execute any Short Sales during the period from the date hereof until the earlier of such time as (i) the transactions contemplated by this Agreement are first
publicly announced or (ii) this Agreement is terminated in full. The Investor covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company, the Investor will maintain (and will cause
its Affiliates, authorized representatives and advisors who are aware of the transactions contemplated by the Transaction Documents) to maintain the confidentiality of all disclosures made to it in connection with the transactions contemplated by
the Transaction Documents (including the existence and terms of such transactions). The Investor understands and acknowledges that the SEC currently takes the position that coverage of Short Sales of shares of the Common Stock “against the
box” prior to effectiveness of a resale registration statement with securities included in such registration statement would be a violation of Section 5 of the 1933 Act, as set forth in Item 239.10 of the Securities Act Rules Compliance
and Disclosure Interpretations compiled by the Office of Chief Counsel, Division of Corporation Finance, and covenants that neither it nor any Affiliates acting on its behalf or pursuant to any understanding with it will execute any such Short
Sales. 


  

	 	Section 5.	 Conditions to Closing. 



 

	 	5.1	 Conditions to the Investor’s Obligations. The obligation of the Investor to

contemplated by the Transaction Documents. 
 (f) The Company shall have delivered a certificate, executed on behalf of the
Company by an officer of the Company, dated as of the Closing Date, certifying to the fulfillment of the conditions specified in subsections (a) through (c). (e), (h) and (i) of this Section 5.1.

(b) The Investor shall have performed in all material respects all obligations and covenants herein required to be performed
by them on or prior to the Closing Date. 
 (c) The Investor shall have executed and delivered the Registration Rights
Agreement and an Investor Questionnaire. 
 (d) The Investor shall have paid in full its purchase price to the Company. 

 

	 	5.3	 Termination of Obligations to Effect Closing; Effects. 



(a) The obligations of the Company, on the one hand, and the Investor, on the other hand, to effect the Closing shall
terminate as follows: 
 (i) upon the mutual written consent of the Company and the Investor; 

(ii) by the Company if any of the conditions set forth in Section 5.2 shall have become incapable of

its obligation to effect the Closing. 
 (b) Nothing in this Section 5.3 shall be deemed to
release either party from any liability for any breach by such party of the terms and provisions of the Transaction Documents or to impair the right of either party to compel specific performance by the other party of its obligations under the
Transaction Documents. 
  

	 	Section 6.	 Miscellaneous. 



 

	 	6.1	 Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and

deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail or other transmission method and any counterpart so delivered shall be deemed to have been duly

	 	6.6	 No Finder’s Fees. Each party represents that it neither is nor will be obligated
for any finder’s fee or commission in connection with this transaction. The Investor agrees to indemnify and to hold harmless the Company from any liability for any commission or compensation in the




  
 20 














	 	 
nature of a finder’s or broker’s fee arising out of this transaction (and the costs and expenses of defending against such liability or asserted liability) for which the Investor
or any of the Investor’s officers, employees or representatives is responsible. The Company agrees to indemnify and hold harmless the Investor from any liability for any commission or compensation in the nature of a finder’s or
broker’s fee arising out of this transaction (and the costs and expenses of defending against such liability or asserted liability) for which the Company or any of its officers, employees or representatives is responsible.

	 	6.9	 Amendments. Any term of this Agreement may be amended or terminated only with the written consent of
the Company and the Investor. 


  

	 	6.10	 Severability. If one or more of the terms or provisions of this Agreement is held by a court of
competent jurisdiction to be void, invalid, or unenforceable in any situation in any jurisdiction, such holding shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the
void, invalid, or unenforceable term or provision in any other situation or in any other jurisdiction, and the term or provision shall be considered severed from this Agreement solely for such situation and solely in such jurisdiction, unless the
void, invalid, or unenforceable term or provision is of such essential importance to this Agreement that it is to be reasonably assumed that the parties hereto would not have entered into this Agreement without the void, invalid, or unenforceable
term or provision. If the final judgment of such court declares that any term or provision hereof is void, invalid, or unenforceable, the parties hereto agree to: (a) reduce the scope, duration, area, or applicability of the term or provision




  
 21 














	 	 
or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as so reduced or amended to be enforceable; and (b) make a good-faith effort to replace
any void, invalid, or unenforceable term or provision with a valid and enforceable term or provision such that the objectives contemplated by the parties hereto when entering this Agreement may be realized. 



 

	 	6.11	 Entire Agreement. This Agreement constitutes the full and entire understanding and agreement between
the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. 



 

	 	6.12	 Specific Enforcement. The parties hereto agree that irreparable damage would occur in the event that
any of the provisions of this Agreement were not performed in accordance with their specific intent or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent or cure breaches
of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they may be entitled by law or equity. 



 

	 	6.13	 Exclusive Jurisdiction; Venue. Each of the parties hereto irrevocably agrees that any legal action or
proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by another party
hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery, or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any federal court within the State of
Delaware, or, if both the Delaware Court of Chancery and the federal courts within the State of Delaware decline to accept jurisdiction over a particular matter, any other state court within the State of Delaware, and, in each case, any appellate
court therefrom. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and
agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to
