determined in accordance with Section 2.2(c). The date and time of the Closing shall be 10:00 a.m., New York City Time,
on the Closing Date. The Closing shall take place by electronic communication and delivery of the items to be delivered at Closing
by facsimile or other electronic transmission.



(b)       Dilutive
Issuances.



(1)       For
purposes of this Section 2.1(b), the following terms shall have the following meanings:



(A)       “Common
Share Equivalents” means any securities of the Company which would entitle the holder thereof to acquire at any time
Common Shares, including, without limitation, any debt, preferred stock, rights, options, warrants or other instrument that is
at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive Common Shares.



(B)       “Exempt
Issuance” means any issuance of (1) shares of capital stock upon any reclassification, stock split or combination, stock
dividend or similar proportionately applied change to the Company’s outstanding capital stock; (2) Common Shares or Common
Share Equivalents to employees, consultants, officers or directors of the Company pursuant to any stock or option plan duly adopted

that such securities and any term thereof have not been amended since the date of this Agreement to increase the number of securities
or to decrease the issue price, exercise price, exchange price or conversion price of such securities, (4) securities issued pursuant
to acquisitions or strategic transactions approved by a majority of the disinterested directors of the Company, provided that
any such issuance shall only be to an entity (or to the equity holders of an entity) which is, itself or through its subsidiaries
or affiliates, an operating company or an owner of an asset in a business synergistic with the business of the Company or its
Subsidiaries and shall provide to the Company or its Subsidiaries benefits in addition to the investment of funds.



5







(2)       If
at any time within 12 months from the date of this Agreement, the Company issues additional Common Shares or Common Share Equivalents,
excluding any shares issued in connection with an Exempt Issuance, at a purchase price per share less than the Purchase Price
(a “Dilutive Issuance”), each Investor shall be entitled to receive without additional consideration such number
of additional Common Shares (the “Supplemental Shares”) equal to the number determined by dividing such Investor’s
Investment Amount by the “Revised Purchase Price” (as derived based on the formula below), less the number
of Purchased Shares purchased by such Investor and any Supplemental Shares previously issued to such Investor as a result of any
prior Dilutive Issuance.



CP2
= CP1 x (A+B) / (A+C)



“CP2”	=	Revised
Purchase Price



“CP1”	=	Original
Purchase Price



“A”	=	Number
of Common Shares outstanding on a fully diluted basis immediately prior to such Dilutive Issuance;



“B”	=	Number
of Common Shares that would have been issued if such additional Common Shares or Common Share Equivalents issued in the Dilutive
Issuance had been issued at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the
Company in respect of such issue by CP1); and



“C”	=	Number
of shares of stock issued in the Dilutive Issuance.



Notwithstanding
anything herein to the contrary, in no event shall: (a) the Purchased Shares, when aggregated with the Supplemental Shares, exceed:
(i) 19.99% of the issued and outstanding Common Shares as of the date of this Agreement (the “Cap Amount”);
or (ii) with respect to Purchased Shares and Supplemental Shares issued or issuable to insiders of the Company (as contemplated
by Section 3.2(h)), 10% of the issued and outstanding Common Shares as of the date of this Agreement (the “Insider Cap
Amount”); or (iii) with respect to Purchased Shares and Supplemental Shares issued or issuable to a Person or “group”
within the meaning of Section 13(d) of the Exchange Act, when aggregated with all other Common Shares beneficially owned by such
Person or group within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder,
20% of the issued and outstanding Common Shares as of the date of this Agreement (the “Change of Control Cap Amount”)
if the issuance of Supplemental Shares to such Person or “group” would cause such Person or “group” to
become the largest shareholder position of the Company, or (b) the Revised Purchase Price be less than 85% of the Purchase Price
(the “Floor Price”). In the event: (a) the number of Supplemental Shares issuable pursuant to this Section
2.1(b), when aggregated with the Purchased Shares, would exceed the Cap Amount or the Insider Cap Amount or the Change of Control
Cap Amount, as applicable (the “Excess Shares”), or (b) in the event the Revised Purchase Price is less than
the Floor Price, then the Company shall use its reasonable best efforts to obtain shareholder approval as soon as commercially
practicable after the Dilutive Issuance to issue the Excess Shares or approve the Revised Purchase Price in accordance with the
requirements of the Trading Market and the TSX, if applicable, and in such event the Excess Shares shall not be issued until or
unless such shareholder approval is duly obtained. Any Supplemental Shares available for issuance without exceeding the Cap Amount
or the Insider Cap Amount, as applicable, shall be apportioned among and issued to the Investors on a pro rata basis based on
the ratio of such Investor’s Investment Amount to the aggregate Investment Amount of all the Investors combined.



6







The
requirements of this Section 2.1(b) shall apply upon the occurrence of each successive Dilutive Issuance, subject to the limitations
set forth in the preceding paragraph.



2.2       Pre-Closing

(a)       Prior
to the Closing, each Investor shall deliver to a Company account, pursuant to the wire instructions which are provided as Exhibit
B hereto (the “Company Account”), the aggregate amount such Investor desires to invest in Purchased Shares,
as set forth on such Investor’s signature page to this Agreement, in U.S. dollars and in immediately available funds (the
“Investment Amount”), which Investment Amount shall be returned to the Investor by the Company solely in the
event of a termination of this Agreement pursuant to Section 7.1.



(b)       At
or prior to the Closing, each Investor shall also deliver or cause to be delivered to the Company the following:

completed and executed Investor signature page to this Agreement;



(ii)       a

its Transfer Agent, instructing the Transfer Agent to issue in book entry form, inclusive of such restrictive and other legends
as set forth in Section 4.1, a number of Purchased Shares equal to such Investor’s Investment Amount divided by the

seeking to revoke, limit or curtail such power or authority or qualification.

on the part of the Company, and no further consent or action is required by the Company, its Board of Directors or its shareholders.
Each of the Transaction Documents to which it is a party has been (or upon delivery will be) duly executed by the Company and
is, or when delivered in accordance with the terms hereof, will constitute, the valid and binding obligation of the Company enforceable

its Subsidiaries on a consolidated basis. Other than the Company changing its accounting principles from IFRS to GAAP commencing
with the first quarter of 2016, there has been no material change in the Company’s accounting policies, except as described
in the notes to the Company Financial Statements, since December 31, 2015. All Material Contracts to which the Company or any
Subsidiary is a party or to which the property or assets of the Company or any Subsidiary are subject are included as part of
or identified in the Public Disclosure Record.

(h)       Absence
of Litigation. Except as disclosed in the Public Disclosure Record, there is no action, suit, claim, or Proceeding pending,
or, to the Company’s knowledge, threatened, before or by any court, public board, government agency, self-regulatory organization

of any facts or circumstances which might give rise to any of the foregoing. The Company and its Subsidiaries have taken reasonable

SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND
MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS (I) AS PART OF THEIR
DISTRIBUTION AT ANY TIME OR (II) OTHERWISE UNTIL SIX MONTHS AFTER THE LATER OF THE COMMENCEMENT OF THE OFFERING THEREOF AND THE
CLOSING DATE, EXCEPT IN EITHER CASE IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT. NO HEDGING TRANSACTION CAN BE CONDUCTED

Such
Investor understands that the legends set forth above shall be removed and the Company shall issue a certificate or other instrument

the future be required by law to disclose such Investor’s name and other information relating to this Agreement and such
Investor’s subscription hereunder, on a confidential basis, pursuant to the PCMLTFA. To the best of its knowledge: (i) none
of the funds representing the Investment Amount to be provided by such Investor: (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 or any other jurisdiction, or (B) are being
tendered on behalf of a person or entity who has not been identified to such Investor; and (ii) such Investor shall promptly notify

IVOTHER AGREEMENTS OF THE PARTIES



4.1       Transfer
Restrictions.



(a)       The
Investors covenant that the Purchased Shares will be disposed of only pursuant to an effective registration statement or prospectus
under, and in compliance with the requirements of, the Securities Act and applicable Canadian securities laws or pursuant to an
available exemption from the registration or prospectus requirements of the Securities Act or applicable Canadian securities laws,
as applicable, and in compliance with applicable state securities laws. In connection with any transfer of Purchased Shares other
than pursuant to an effective registration statement, prospectus or to the Company, the Company may require the transferor to
provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably
satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act. Notwithstanding
the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its Transfer Agent,
without any such legal opinion, except to the extent that the Transfer Agent requests such legal opinion, any transfer of Purchased
Shares by an Investor to an Affiliate of such Investor, provided that such transfer does not involve a “sale” within
the meaning of Section 2(a)(3) of the Securities Act and provided that such Affiliate does not request any removal of any existing
legends on any certificate evidencing the Purchased Shares.



(b)       The
Investors agree to the imprinting, until no longer required by this Section 4.1, of the legends, in substantially the following
form, on any certificate or other instrument evidencing any of the Purchased Shares:



THESE
SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND
MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS (I) AS PART OF THEIR
DISTRIBUTION AT ANY TIME OR (II) OTHERWISE UNTIL SIX MONTHS AFTER THE LATER OF THE COMMENCEMENT OF THE OFFERING THEREOF AND THE
CLOSING DATE, EXCEPT IN EITHER CASE IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT. NO HEDGING TRANSACTION CAN BE CONDUCTED
WITH REGARD TO THE SECURITIES EXCEPT AS PERMITTED BY THE SECURITIES ACT. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM BY REGULATION
S PROMULGATED UNDER THE SECURITIES ACT.



THESE
SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER ANY APPLICABLE STATE SECURITIES LAWS
AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT
AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS.



19







(c)       The
Investors agree that any physical certificates evidencing the Purchased Shares will be endorsed with, or the ownership statement
issued under a direct registration system or other electronic book-entry system will bear, a legend setting out resale restrictions
under applicable Canadian securities laws in substantially the following form:



UNLESS
PERMITTED UNDER APPLICABLE CANADIAN PROVINCIAL SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY
BEFORE OCTOBER 21, 2016.



Additionally,
the Investors agree that any physical certificates representing the Purchased Shares will be endorsed with a legend setting out
resale restrictions pursuant to policies of the TSX in substantially the following form:



THE
SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE (THE “TSX”); HOWEVER, THE SAID
SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF THE TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE
REPRESENTING SUCH SECURITIES IS NOT ‘GOOD DELIVERY’ IN SETTLEMENT OF TRANSACTIONS ON THE TSX.



Certificates
or another instrument evidencing the Purchased Shares shall not be required to contain such legend or any other legend (i) following
any sale of such Purchased Shares pursuant to an effective registration statement or prospectus under the Securities Act or Canadian
securities laws, as applicable, (ii) pursuant to Rule 144 if the holder provides the Company with a legal opinion (and the documents
upon which the legal opinion is based) reasonably acceptable to the Company to the effect that the Purchased Shares can be sold
under Rule 144 or (iii) if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion
is based) reasonably acceptable to the Company to the effect that the legend is not required under applicable requirements of
the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the SEC). The Company
may not make any notation on its records or give instructions to the Transfer Agent that expand the restrictions on transfer set
forth in this Section 4.1.

Article
VIINDEMNIFICATION



6.1
Indemnification of Investors. The Company will indemnify and hold each Investor and its directors, officers, shareholders,
members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title), each Person who controls such Investor (within the meaning of Section
15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners
or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack
of such title or any other title) of such controlling person (each, an “Investor Party”) harmless from any
and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts
paid in settlements, court costs and reasonable attorneys’ fees and reasonable costs of investigation that any such Investor
Party may suffer or incur, as a result of or relating to third party claims against such Investor relating to any breach of any
of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction
Documents, provided that that such a claim for indemnification relating to any breach of any of the representations or warranties
made by the Company in this Agreement is made within six months from the Closing. The Company will not be liable to any Investor
Party under this Agreement to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any
Investor Party’s breach of any of the representations, warranties, covenants or agreements made by such Investor Party in
this Agreement or in the other Transaction Documents.



6.2
Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the “Indemnified Person”)
of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding
or investigation in respect of which indemnity may be sought pursuant to Section 6.1, such Indemnified Person shall promptly
notify the Company in writing, and the Company shall assume the defense thereof, and shall assume the payment of all fees and
expenses; provided, however , that the failure of any Indemnified Person so to notify the Company shall not relieve the Company
of its obligations hereunder except to the extent that the Company is actually prejudiced by such failure to notify. In any such
proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to
the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ
counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel
to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential
differing interests between them in such proceeding; provided, that, in the case of the foregoing clauses (i) through (iii), the
Company shall not pay for more than one counsel for all Indemnified Persons. The Company shall not be liable for any settlement
of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned.
Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned,
the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person
is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement
includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

the same agreement. In the event that any signature is delivered by facsimile transmission or email attachment, such signature
shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same

7.12
Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and
the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.



7.13
Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document
are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the
performance of the obligations of any other Investor under any Transaction Documents. The decision of each Investor to purchase
Common Shares pursuant to this Agreement has been made by such Investor independently of any other Investor and independently
of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities,
results of operations, condition (financial or otherwise) or prospects of the Company which may have been made or given by any
other Investor or by any agent or employee of any other Investor, and no Investor or any of its agents or employees shall have
any liability to any other Investor (or any other person) relating to or arising from any such information, materials, statements
or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall
be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create
a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Document. Each Investor acknowledges that no other Investor has acted as agent for such Investor
in connection with making its investment hereunder and that no other Investor will be acting as agent of such Investor in connection
with monitoring its investment hereunder. Each Investor shall be entitled to independently protect and enforce its rights, including
without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary
for any other Investor to be joined as an additional party in any Proceeding for such purpose.



25







7.14
Representations. Each Investor agrees that, except for the representations and warranties
contained in Section 3.1, the Company makes no other representations or warranties, and the Company hereby disclaims any
other representations or warranties made by itself or any of its directors, officers employees, investment bankers, financial
advisors, attorneys, accountants, agents and other representatives (collectively, “Representatives”), with
respect to the execution and delivery of this Agreement and the other Transaction Documents, notwithstanding the delivery or disclosure
to any other party or any other party’s Representatives of any document or other information with respect to any one or
more of the foregoing. Without limiting the generality of the foregoing, and notwithstanding any otherwise express representations
and warranties made by the Company in this Agreement, each of the Investors agrees that neither the Company nor any of its Subsidiaries
makes or has made any representation or warranty with respect to (i) any projections, forecasts, estimates, plans or budgets or
future revenues, expenses or expenditures, future results of operations (or any component thereof), future cash flows (or any
component thereof) or future financial condition (or any component thereof) of the Company or any of its Subsidiaries or the future
business, operations or affairs of the Company or any of its Subsidiaries heretofore or hereafter delivered to or made available
to it, or (ii) any other information, statements or documents heretofore or hereafter delivered to or made available to it with
respect to the Company or any of its Subsidiaries or the business, operations or affairs of the Company or any of its Subsidiaries,
except to the extent and as expressly covered by a representation and warranty made in this Agreement.
