(c)From the date hereof until one (1) year after Closing, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Shares or Common Share Equivalents (or a combination of units thereof) involving a Variable Rate Transaction.  “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional Common Shares either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the Common Shares at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Shares or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market” offering, whereby the Company may issue securities at a future determined price, regardless of whether shares pursuant to such agreement have actually been issued and regardless of whether such agreement is subsequently canceled; provided that, following the expiration of the restrictive period set forth in Section 2.34(b) above, neither the entry into an ATM sales agreement nor the issuance of Common Shares pursuant thereto shall be considered a “Variable Rate Transaction”.  Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

(d)If Shareholder Approval has not been obtained and deemed effective as of the conclusion of the period set forth in Section 2.34(a) and/or Section 2.34(b), such sections will extend to the earlier of (1) an additional 30 months and (2) Shareholder Approval being obtained and deemed effective.  Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

(e)Notwithstanding the foregoing, this Section 2.34 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall be an Exempt Issuance.

3.Representations, Warranties and Covenants of the Purchasers. Each Purchaser hereby represents, warrants and covenants to the Company, as applicable, severally and not jointly, that:

3.1Authorization. The Purchaser has full power and authority to enter into the Transaction Agreements. The Transaction Agreements to which the Purchaser is a party, when executed and delivered by the Purchaser, will constitute valid and legally binding obligations of the Purchaser, enforceable in accordance with their terms, except (a) as limited by Enforceability Qualifications, or (b) to the extent the indemnification provisions contained in the Registration Rights Agreement may be limited by applicable U.S. federal, or U.S. state or Canadian provincial securities laws.

​

3.2Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Securities to be acquired by the Purchaser will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Securities. The Purchaser has not been formed for the specific purpose of acquiring the Securities.

3.3Disclosure of Information. The Purchaser acknowledges that it has received and has had the chance to review, all the information that it has requested relating to the Company and the purchase of the Securities including, but not limited to, the Investor Presentation annexed as Exhibit E hereto. In addition to the foregoing, such Purchaser acknowledges that it has been afforded: (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Such Purchaser acknowledges and agrees that neither the Placement Agents nor any Affiliate of the Placement Agents has provided such Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary or desired.  Neither the Placement Agents nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities and the Placement Agents and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser agrees need not be provided to it.  In connection with the issuance of the Securities to such Purchaser, neither the Placement Agents nor any of its Affiliates have acted as a financial advisor or fiduciary to such Purchaser. Neither such inquiries nor any other investigation conducted by or on behalf of such Purchaser or its representatives or counsel shall limit, modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in Section 2 hereof or the other Transaction Documents.

3.4Information on Purchaser. Such Purchaser is, and will be at the time of the exercise of the Warrants, if any, an “accredited investor,” as such term is defined in Rule 501(a) of Regulation D promulgated by the SEC under the Securities Act and as set forth on the Investor Questionnaire in the form annexed hereto as Exhibit D (the “Investor Questionnaire”).

3.5High Risk and Speculative Investment. The Purchaser recognizes that the purchase of the Securities involves a high degree of risk including, but not limited to the following: (a) the Company is likely to require funds in addition to the proceeds of the Offering; (b) an investment in the Company is highly speculative, and only investors who can afford the loss of their entire investment should consider investing in the Company and the Securities; (c) the Purchaser may not be able to liquidate its investment; (d) transferability of the Securities is limited;

​

-25-

​

and (e) the Company may issue additional securities in the future which have rights and preferences that are senior to those of the Securities.

3.6Restricted Securities. The Purchaser understands that the Securities have not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Securities are (or will when issued be) “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Securities indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Securities for resale except as set forth in the Registration Rights Agreement. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy. The Purchaser also understands that the Securities have not been, and will not be, qualified for distribution by prospectus under the securities laws of any province or territory of Canada and will not be offered or sold in Canada during the course of their distribution except pursuant to a Canadian prospectus or prospectus exemption under National Instrument 45-106 Prospectus and Registration Exemptions. The Purchaser acknowledges being advised to obtain legal advice regarding compliance with any applicable securities law resale restrictions that may be applicable prior to effecting a resale of the Securities to a purchaser in Canada, the United States or elsewhere, or through an exchange or market in Canada, the United States or elsewhere.

3.7General Solicitation. The offer to sell the Securities was directly communicated to such Purchaser by the Company or the Placement Agents. The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice, or other communication regarding the Securities published in any newspaper, magazine or similar media or on the internet, or broadcast over television or radio or the internet, or presented in any seminar or meeting whose attendees have been invited by any general solicitation or general advertisement.

3.8For ERISA plans only. The fiduciary of the ERISA plan (the “Plan”) represents that such fiduciary has been informed of and understands the Company’s investment objectives, policies and strategies, and that the decision to invest “plan assets” (as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities. The Purchaser fiduciary of the Plan (a) is responsible for the decision to invest in the Company; (b) is independent of the Company or any of its affiliates; (c) is qualified to make such investment decision; and (d) in making such decision, the fiduciary of the Plan has not relied primarily on any advice or recommendation of the Company or any of its affiliates.

3.9Disqualification. The Purchaser represents that neither the Purchaser nor any person or entity with whom the Purchaser shares beneficial ownership of the Securities is

​

-26-

​

subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act.

3.10Legends. (a) The Purchaser understands that certificates or DRS Statements representing the Common Shares, Pre-Funded Warrants and Warrants comprising the Units, and any Warrant Shares issuable upon exercise of the Warrants (collectively, the “Securities”), may be notated with the following legend:

“THE SECURITIES REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND SUCH SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS IS AVAILABLE AND THE COMPANY RECEIVES AN OPINION OF COUNSEL TO THE HOLDER OF SUCH SECURITIES, WHICH COUNSEL AND OPINION ARE SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED, OR OTHERWISE TRANSFERRED IN THE MANNER CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS.”

(a)Such Securities may also bear any legend set forth in, or required by, the other Transaction Agreements.

(b)Such Securities may also bear any legend required by the securities laws of any state to the extent such laws are applicable to the Securities represented by the certificate or DRS Statement so legended.

3.11Foreign Investors. If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), the Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Securities, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, exercise, sale, or transfer of the Securities. The Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the Purchaser’s jurisdiction.

3.12Exculpation Among Purchasers. The Purchaser acknowledges that it is not relying upon any Person, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. The Purchaser agrees that neither any Purchaser nor the respective controlling Persons, officers, directors, partners, agents or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore taken or omitted to be taken by any of them in connection with the purchase of the Securities.

3.13Residence and Location. If the Purchaser is an individual, then the Purchaser resides and is located in the state identified in the address of the Purchaser set forth on Exhibit B hereto; if the Purchaser is a partnership, corporation, limited liability company or other entity, then the office or offices of the Purchaser in which its principal place of business is identified is the address or addresses of the Purchaser set forth on Exhibit B hereto. Each Purchaser certifies that is it not located or resident in any province or territory of Canada.

3.14Compliance. The Purchaser is knowledgeable of or has been independently advised as to, the applicable securities laws having application in the jurisdiction in which it is present or which applies to the offer and sale of the Units to it. The Purchaser is acquiring the Units pursuant to exemptions from prospectus or equivalent requirements under applicable securities laws. The Purchaser will not sell, transfer or dispose of the Securities except in accordance with (i) securities laws of Canada or pursuant to a Canadian prospectus or prospectus exemption under National Instrument 45-106 Prospectus and Registration Exemptions and (ii) securities laws of the United States, or other applicable jurisdiction, and the Purchaser acknowledges the Company shall have no obligation to register any such purported sale, transfer or disposition which violates applicable Canadian, United States or other securities laws. The Purchaser is purchasing the Units with investment intent and not with a view to distribution.
