2. PURCHASE AND SALE OF COMMON STOCK.

Subject to the terms and conditions set forth in this Agreement, the Company has
the right, but not the obligation, to sell to the Investor, in its sole and
absolute discretion, and the Investor has the obligation to purchase from the
Company, Purchase Shares as follows:

(a) Commencement of Sales of Common Stock. Following the satisfaction of the
conditions (the “Commencement”) as set forth in Sections 7 and 8 below (the date
of satisfaction of such conditions, the “Commencement Date”), the Investor shall
purchase $750,000 worth of Purchase Shares (such purchase the “Initial Purchase”
and such Purchase Shares are referred herein as “Initial Purchase Shares”) at a
price equal to $0.38 per share. Beginning five (5) Business Days following the
Commencement Date, the Company shall have the right, but not the obligation, in
its sole and absolute discretion, to deliver to the Investor from time to time a
Purchase Notice directing the Investor to buy Purchase Shares (each such
purchase a “Regular Purchase”) in any amount up to two hundred fifty thousand
(250,000) Purchase Shares per Purchase Notice at the applicable Purchase Price.
The Company may deliver a Purchase Notice only between 4:01 p.m. Eastern time
and 6:00 p.m. Eastern time on the applicable Purchase Date or between 8:00 a.m.
Eastern time and 9:00 a.m. Eastern time on the Business Day next following the
applicable Purchase Date. The Company may deliver multiple Purchase Notices to
the Investor so long as at least one (1) Business Day has passed since the most
recent Regular Purchase was completed.

(b) Accelerated Purchases. At any time after the Commencement Date, the Company
shall also have the right, but not the obligation, in its sole and absolute
discretion, to deliver to the Investor from time to time an Accelerated Purchase
Notice directing the Investor to buy, in addition to any Regular Purchase, up to
One Hundred Thousand Dollars ($100,000) worth of Purchase Shares (each such
purchase an “Accelerated Purchase” and the amount so purchased the “Accelerated
Purchase Amount”) per Accelerated Purchase Notice at the applicable Accelerated
Purchase Price (as defined below), provided that the Closing Sale Price of the
Common Stock must not be below $0.50 (subject to equitable adjustment for any
reorganization, recapitalization, non-cash dividend, stock split or other
similar transaction) on the applicable Purchase Date (the “Accelerated Purchase
Threshold Price”). The Accelerated Purchase Amount may be increased to up to Two
Hundred Thousand Dollars ($200,000.00) per Accelerated Purchase Notice if the
Closing Sale Price of the Common Stock is not below $0.80 (subject to equitable
adjustment for any reorganization, recapitalization, non-cash dividend, stock
split or other similar transaction) on the applicable Purchase Date. The
Accelerated Purchase Amount may be increased to up to Three Hundred Thousand
Dollars ($300,000.00) per Accelerated Purchase Notice if the Closing Sale Price
of the Common Stock is not below $1.10 (subject to equitable adjustment for any
reorganization, recapitalization, non-cash dividend, stock split or other
similar transaction) on the applicable Purchase Date. The Accelerated Purchase
Amount may be increased to up to Four Hundred Thousand Dollars ($400,000.00) per
Accelerated Purchase Notice if the Closing Sale Price of the Common Stock is not
below $1.50 (subject to equitable adjustment for any reorganization,
recapitalization, non-cash dividend, stock split or other similar transaction)
on the applicable Purchase Date. The Accelerated Purchase Amount may be
increased to up to Five Hundred Thousand Dollars ($500,000.00) per Accelerated
Purchase Notice if the Closing Sale Price of the Common Stock is not below $2.00
(subject to equitable adjustment for any reorganization, recapitalization,
non-cash dividend, stock split or other similar transaction) on the applicable
Purchase Date. As used herein, the term “Accelerated Purchase Price” shall mean
a price per Purchase Share equal to the lesser of (i) the lowest Sale Price of
the Common Stock on the applicable Purchase Date for such Accelerated Purchase
or (ii) the lowest Purchase Price during the five (5) Business Days immediately
prior to the applicable Purchase Date for such Accelerated Purchase (assuming
for purposes of this Section 2(b) that the Company had delivered a Purchase
Notice on each of such five Business Days, whether or not such Purchase Notice
is actually delivered). However, if on any Purchase Date the Closing Sale Price
of the Common Stock is below the Accelerated Purchase Threshold Price, such
Accelerated Purchase shall be void and the Investor’s obligations to buy
Purchase Shares in respect of that Accelerated Purchase Notice shall be
terminated. Thereafter, the Company shall again have the right to submit an
Accelerated Purchase Notice as set forth herein by delivery of a new Accelerated
Purchase Notice only if the Closing Sale Price of the Common Stock is at or
above the Accelerated Purchase Threshold Price on the applicable Purchase Date.
The Company may deliver an Accelerated Purchase Notice only between 4:01 p.m.
Eastern time and 6:00 p.m. Eastern time on the applicable Purchase Date or
between 8:00 a.m. Eastern time and 9:00 a.m. Eastern time on the Business Day
next following the applicable Purchase Date. The Company may deliver multiple
Accelerated Purchase Notices to the Investor so long as at least one (1)
Business Day has passed since the most recent Accelerated Purchase was
completed.

--------------------------------------------------------------------------------

(c) Payment for Purchase Shares. The Investor shall pay to the Company an amount
equal to the Purchase Amount or Accelerated Purchase Amount (as applicable) as
full payment for the Purchase Shares specified in the Purchase Notice or the
Accelerated Purchase Notice (as applicable), in each case calculated in
accordance with Sections 2(a) or 2(b) (as applicable), via wire transfer of
immediately available funds to such account as the Company may from time to time
designate by written notice in accordance with this Agreement, on the same
Business Day that the Investor receives such Purchase Shares, if they are
received by the Investor before 1:00 p.m. Eastern time, or if received by the
Investor after 1:00 p.m. Eastern time, on the next Business Day. The Company
shall, or shall cause the Transfer Agent to, electronically transfer such
Purchase Shares as DWAC Shares to an account or accounts specified in writing by
the Investor to the Company against payment therefor. The Company shall not
issue any fraction of a share of Common Stock in connection with any Regular
Purchase or Accelerated Purchase, and, if the issuance would result in the
issuance of a fraction of a share of Common Stock, the Company shall round such
fraction of a share of Common Stock up or down to the nearest whole share. All
payments made under this Agreement shall be made in lawful money of the United
States of America via wire transfer of immediately available funds to such
account as the Company may from time to time designate by written notice in
accordance with the provisions of this Agreement. Whenever any amount expressed
to be due by the terms of this Agreement is due on any day that is not a
Business Day, the same shall instead be due on the next succeeding day that is a
Business Day.

(d) Purchase Price Floor; No Sales on TSX. Notwithstanding anything to the
contrary contained in this Agreement, the Company and the Investor shall not
effect any purchases under this Agreement if the Purchase Price or Accelerated
Purchase Price would be less than the Floor Price. The Company and the Investor
acknowledge and agree that no Securities that may be issued pursuant to this
Agreement will be offered for sale or sold on the TSX.

Stock pursuant to this Agreement, and the Investor shall not purchase or acquire

giving effect thereto, the aggregate number of shares of Common Stock that would
be issued pursuant to this Agreement and the transactions contemplated hereby
would exceed the lesser of: (A) subject to Section 2(e)(ii) below, 17,007,580
shares of Common Stock (which number of shares shall be reduced, on a
share-for-share basis, by the number of shares of Common Stock issued or
issuable pursuant to any transaction or series of transactions that may be
aggregated with the transactions contemplated by this Agreement under applicable
rules of the NYSE MKT or any other Principal Market on which the Common Stock
may be listed or quoted) (the “Exchange Cap”), unless and until the Company
elects to solicit stockholder approval of the transactions contemplated by this
Agreement and the stockholders of the Company have in fact approved the
transactions contemplated by this Agreement in accordance with the applicable
rules and regulations of the NYSE MKT, any other Principal Market on which the
Common Stock may be listed or quoted, and the Certificate of Incorporation and
Bylaws of the Company; and (B) for so long as the Company is subject to the
limitations set forth in General Instruction I.B.6. of Form S-3, the maximum
number of shares of Common Stock that the Company may issue pursuant to this
Agreement and the transactions contemplated hereby without exceeding the
limitations set forth in General Instruction I.B.6. of Form S-3 (the

the term “Maximum Share Cap” shall mean the lesser of (i) the Exchange Cap, to
the extent applicable to the transactions contemplated by this Agreement, and
(ii) the Registration Statement Eligibility Cap, to the extent applicable to the
transactions contemplated by this Agreement. For the avoidance of doubt, the
Company may, but shall be under no obligation to, request its stockholders to
approve the transactions contemplated by this Agreement; provided, that if
stockholder approval is not obtained in accordance with this Section 2(e)(i),
the Exchange Cap shall be applicable for all purposes of this Agreement and the
transactions contemplated hereby at all times during the term of this Agreement
(except as set forth in Section 2(e)(ii) below).

--------------------------------------------------------------------------------

(ii) At-Market Transaction. Notwithstanding Section 2(e)(i) above and subject to
the prior approval of the NYSE MKT or any other Principal Market on which the
Common Stock may be listed or quoted (to the extent required), the Exchange Cap
shall not be applicable for any purposes of this Agreement and the transactions
contemplated hereby, solely to the extent that the issuances and sales of Common
Stock pursuant to this Agreement are deemed to be at a price equal to or in
excess of the greater of book or market value of the Common Stock as calculated
in accordance with the applicable rules of the NYSE MKT or any other Principal
Market on which the Common Stock may be listed or quoted (it being hereby
acknowledged and agreed that the Exchange Cap shall be applicable for all
purposes of this Agreement and the transactions contemplated hereby at all other
times during the term of this Agreement, unless the stockholder approval
referred to in Section 2(e)(i) is obtained).

(iii) General. The Company shall not issue any shares of Common Stock pursuant
to this Agreement and the transactions contemplated hereby if such issuance
would reasonably be expected to result in (A) a violation of the Securities Act
or non-compliance with General Instruction I.B.6. of Form S-3 or (B) a breach of
the rules and regulations of the NYSE MKT or any other Principal Market on which
the Common Stock may be listed or quoted, or the rules and regulations of the
TSX. The provisions of this Section 2(e) shall be implemented in a manner
otherwise than in strict conformity with the terms hereof only if necessary to
ensure compliance with the Securities Act, General Instruction I.B.6. of Form
S-3, and the rules and regulations of the NYSE MKT or any other Principal Market
on which the Common Stock may be listed or quoted, or the rules and regulations
of the TSX.

(f) Beneficial Ownership Limitation. Notwithstanding anything to the contrary
contained in this Agreement, the Company shall not issue or sell and the
Investor shall not purchase or acquire any shares of Common Stock under this
Agreement which, when aggregated with all other shares of Common Stock then
beneficially owned by the Investor and its affiliates (as calculated pursuant to
Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder), would
result in the beneficial ownership by the Investor and its affiliates of more
than 9.99% of the then issued and outstanding shares of Common Stock (the
“Beneficial Ownership Limitation”). Upon the written or oral request of the
Investor, the Company shall promptly (but not later than 24 hours) confirm
orally or in writing to the Investor the number of shares of Common Stock then
outstanding. The Investor and the Company shall each cooperate in good faith in
the determinations required hereby and the application hereof. The Investor’s
written certification to the Company of the applicability of the Beneficial
Ownership Limitation, and the resulting effect thereof hereunder at any time,
shall be conclusive with respect to the applicability thereof and such result
absent manifest error.

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 Commitment Shares and the reservation for issuance and issuance
of the Purchase Shares) will not (i) result in a violation of the Certificate of

cancellation of, any agreement, indenture or instrument to which the Company or
any of its Subsidiaries is a party, or (iii) subject to the Required Approvals

(f) Filings and Authorizations. Except as disclosed in the SEC Documents and
except where the failure to obtain any such consent, authorization or order or
make any such filing or registration would not reasonably be expected to result
in a Material Adverse Effect, the Company is not required to obtain any consent,
authorization or order of, or make any filing or registration with, any federal,
state, local or foreign court or governmental agency or any federal, state,
local or foreign regulatory or self-regulatory agency in order for it to

required to be filed by the Company under the Securities Act and the Exchange
Act, including pursuant to Section 13(a) or 15(d) thereof, for the two (2) years
preceding the date hereof (or such shorter period as the Company was required by
law or regulation to file such material) (the foregoing materials, including the
exhibits thereto and documents incorporated by reference therein, being
collectively referred to herein as the “SEC Documents”) on a timely basis or has
received a valid extension of such time of filing and has filed any such SEC
Documents prior to the expiration of any such extension. As of their respective
dates, the SEC Documents complied in all material respects with the requirements
of the Securities Act and the Exchange Act, as applicable, and none of the SEC
Documents, when filed, 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. The financial statements of the Company
included in the SEC Documents comply in all material respects with applicable
accounting requirements and the rules and regulations of the SEC with respect
thereto as in effect at the time of filing. Such financial statements have been
prepared in accordance with United States generally accepted accounting
principles applied on a consistent basis during the periods involved (“GAAP”),
except as may be otherwise specified in such financial statements or the notes
thereto and except that unaudited financial statements may not contain all
footnotes required by GAAP, and fairly present in all material respects the
financial position of the Company and its consolidated Subsidiaries as of and
for the dates thereof and the results of operations and cash flows for the
periods then ended, subject, in the case of unaudited statements, to normal,
immaterial, year-end audit adjustments. The Company has made available to the
Investor true and complete copies of all comment letters and substantive
correspondence received by the Company from the SEC during the 12 months

issuer or an equivalent thereof in each of the Provinces of British Columbia,
Alberta and Ontario and is not noted as being in default on any list of
reporting issuers or reporting issuers in default maintained by the securities
commission in each such Province.

--------------------------------------------------------------------------------

(h) Absence of Certain Changes. Except as disclosed in the SEC Documents and
except as contemplated by this Agreement, since the date of the latest audited
financial statements included within the SEC Documents, there has been no
material adverse change in the business, properties, operations, financial
condition or results of operations of the Company or its Subsidiaries. The
Company has not taken any steps, and does not currently expect to take any
steps, to seek protection pursuant to any Bankruptcy Law nor does the Company or
any of its Subsidiaries have any knowledge or reason to believe that its
creditors intend to initiate involuntary bankruptcy or insolvency proceedings.
The Company is financially solvent and is generally able to pay its debts as
they become due.

(i) Absence of Litigation. Except as disclosed in the SEC Documents, there is no
action, suit, proceeding, inquiry or investigation before or by any court,
public board, government agency, self-regulatory organization or body pending
or, to the knowledge of the Company, threatened against or affecting the Company
or any Subsidiary or any of the Company’s or its Subsidiaries’ officers or
directors in their capacities as such, which would, if there were an unfavorable
decision, reasonably be expected to result in a Material Adverse Effect.

(j) Acknowledgment Regarding Investor's Status. The Company acknowledges and
agrees that the Investor is acting solely in the capacity of arm's length
purchaser with respect to the Transaction Documents and the transactions
contemplated hereby and thereby. The Company further acknowledges that the
Investor is not acting as a financial advisor or fiduciary of the Company (or in
any similar capacity) with respect to the Transaction Documents and the
transactions contemplated hereby and thereby and any advice given by the
Investor 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 Investor's purchase of the Securities. The Company
further represents to the Investor that the Company's decision to enter into the
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives and advisors.

(k) No Integrated Offering. Neither the Company, nor any of its affiliates, nor
any Person acting on its or 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 be
integrated with prior offerings by the Company in a manner that would require
stockholder approval pursuant to the rules of the Principal Market on which any
of the securities of the Company are listed or designated or the TSX. The
issuance and sale of the Securities hereunder does not contravene the rules and
regulations of the Principal Market or the TSX.

(l) Intellectual Property Rights. The Company and each Subsidiary have, or have
rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, copyrights, licenses and other similar
intellectual property rights currently employed by them in connection with the
business currently operated by them that are necessary for use in the conduct of
their respective businesses as described in the SEC Documents and which the
failure to so have would not reasonably be expected to have a Material Adverse
Effect (collectively, the “Intellectual Property Rights”). To the knowledge of
the Company, all such Intellectual Property Rights are enforceable and there is
no existing infringement by another Person of any of the Intellectual Property
Rights of the Company or any Subsidiary. Except as set forth in the SEC
Documents, there are no actions, suits or judicial proceedings pending, or to
the Company’s knowledge threatened, relating to patents or proprietary
information to which the Company or any of its Subsidiaries is a party or of
which any property of the Company or any of its Subsidiaries is subject, and
neither the Company nor any of its Subsidiaries has received any written notice
or is otherwise aware of any infringement of or conflict with asserted rights of
any other Person with respect to any Intellectual Property Rights or of any
facts or circumstances which could render any Intellectual Property Rights
invalid or inadequate to protect the interest of the Company and its
Subsidiaries therein, and which infringement or conflict (if the subject of any
unfavorable decision, ruling or finding) or invalidity or inadequacy,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect.

--------------------------------------------------------------------------------

(m) Environmental Laws. The Company and its Subsidiaries (i) are in compliance
with any and all applicable foreign, federal, state and local laws and
regulations relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants (“Environmental Laws”), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval, except in the case of
clauses (i), (ii) and (iii) above, where the failure to so comply or to obtain
such permits, licenses or approvals would not reasonably be expected to have,
either individually or in the aggregate, a Material Adverse Effect.

(n) Title. The Company and the Subsidiaries have good and marketable title in
fee simple to all real property owned by them and good and marketable title in
all personal property owned by them that is material to the business of the
Company and the Subsidiaries, in each case free and clear of all liens,
encumbrances and defects (collectively, “Liens”), except for Liens that do not
materially affect the value of such property and do not materially interfere
with the use made and proposed to be made of such property by the Company and
its Subsidiaries, and Liens for the payment of federal, state or other taxes,
the payment of which is neither delinquent nor subject to penalties, and Liens
relating to project financing which has been disclosed in the SEC Documents. Any
real property and facilities held under lease by the Company and its
Subsidiaries are held by them under valid, subsisting and enforceable leases
with which the Company and the Subsidiaries are in compliance (with such
exceptions as are not material and do not interfere with the use made and
proposed to be made of such property and buildings by the Company and its
Subsidiaries).

(o) Insurance. The Company and each of its Subsidiaries are insured by insurers
of recognized financial responsibility against such losses and risks and in such
amounts as management of the Company believes to be prudent and customary in the
businesses in which the Company and its Subsidiaries are engaged. Neither the
Company nor any of its Subsidiaries 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 not be able 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 without a
significant increase in cost.

(p) Regulatory Permits. The Company and its Subsidiaries possess all material
certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses (collectively, “Material Permits”), and neither the Company nor any
such Subsidiary has received any notice of proceedings relating to the
revocation or modification of any Material Permit.

(q) Tax Status. The Company and each of its Subsidiaries has made or filed (or
requested valid extensions of) all federal, state and foreign income and all
other material tax returns, reports and declarations required by any
jurisdiction to which it is subject (unless and only to the extent that the
Company and each of its Subsidiaries has set aside on its books provisions
reasonably adequate for the payment of all unpaid and unreported taxes) and has
paid all taxes and other governmental assessments and charges that are material
in amount, shown or determined to be due on such returns, reports and
declarations, except those being contested in good faith. There are no unpaid
taxes in any material amount claimed to be due by the taxing authority of any
jurisdiction, and the officers of the Company know of no basis for any such
claim.

(r) Transactions With Affiliates. Except as set forth in the SEC Documents, none
of the officers or directors of the Company and, to the knowledge of the
Company, none of the employees of the Company is presently a party to any
transaction with the Company or any Subsidiary (other than for services as
employees, officers and directors) that is required to be disclosed and is not
disclosed, including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any entity in
which any officer, director, or any such employee has a substantial interest or
is an officer, director, trustee or partner, in each case in excess of $120,000,

other employee benefits, including stock option agreements under any equity
incentive plan of the Company.

(s) Application of Takeover Protections. The Company and its board of directors
have taken or will take prior to the Commencement Date all necessary action, if
any, in order to render inapplicable any control share acquisition, business
combination, poison pill (including any distribution under a rights agreement)
or other similar anti-takeover provision under the Certificate of Incorporation
or the laws of the state of its incorporation which is or could become
applicable to the Investor as a result of the transactions contemplated by this
Agreement, including, without limitation, the Company's issuance of the
Securities and the Investor's ownership of the Securities.

(t) Disclosure. Except with respect to the material terms and conditions of the
transactions contemplated by the Transaction Documents that will be, and to the
extent that they actually are, timely publicly disclosed by the Company, the
Company confirms that neither it nor any other Person acting on its behalf has
provided the Investor or its agents or counsel with any information that it
believes constitutes or might constitute material, non-public information which
is not otherwise disclosed in the Registration Statement or the SEC Documents.
The Company understands and confirms that the Investor will rely on the
foregoing representation in effecting acquisitions and sales of securities of
the Company. All of the disclosure furnished by or on behalf of the Company to
the Investor regarding the Company, its business and the transactions
contemplated hereby, including the SEC Documents and disclosure schedules to
this Agreement, is true and correct in all material respects and does not
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 light of the
circumstances under which they were made, not misleading. The press releases
disseminated by the Company during the twelve months preceding the date of this
Agreement and the SEC Documents taken as a whole do not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made and when made, not misleading. The
Company acknowledges and agrees that the Investor neither makes nor has made any
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in Section 3 hereof.

(u) Foreign Corrupt Practices. Neither the Company, nor to the knowledge of the
Company, any agent or other person acting on behalf of the Company, has (i)
directly or indirectly, used any funds for unlawful contributions, gifts,
entertainment or other unlawful expenses related to foreign or domestic
political activity, (ii) made any unlawful payment to foreign or domestic
government officials or employees or to any foreign or domestic political
parties or campaigns from corporate funds, (iii) failed to disclose fully any
contribution made by the Company (or made by any person acting on its behalf of
which the Company is aware) which is in violation of law, or (iv) violated in
any material respect any provision of the Foreign Corrupt Practices Act of 1977,
as amended.

--------------------------------------------------------------------------------

(v) Registration Statement. The Company has prepared and filed with the SEC in
accordance with the provisions of the Securities Act the Registration Statement.
The Registration Statement was declared effective by order of the SEC on
December 1, 2010. The Registration Statement is effective pursuant to the
Securities Act and available for the issuance of the Securities thereunder, and
the Company has not received any written notice that the SEC has issued or
intends to issue a stop order or other similar order with respect to the
Registration Statement or the Prospectus or that the SEC otherwise has (i)
suspended or withdrawn the effectiveness of the Registration Statement or (ii)
issued any order preventing or suspending the use of the Prospectus or any
Prospectus Supplement, in either case, either temporarily or permanently or
intends or has threatened in writing to do so. The “Plan of Distribution”
section of the Prospectus permits the issuance of the Securities hereunder. At
the time the Registration Statement and any amendments thereto became effective,
at the date of this Agreement and at each deemed effective date thereof pursuant
to Rule 430B(f)(2) of the Securities Act, the Registration Statement and any
amendments thereto complied and will comply in all material respects with the
requirements of the Securities Act and did not and will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading; and
the Base Prospectus and any Prospectus Supplement thereto, at the time such Base
Prospectus or such Prospectus Supplement thereto was issued and on the
Commencement Date, complied and will comply in all material respects with the
requirements of the Securities Act and did not and will not contain an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading; provided that this representation and warranty does
not apply to statements in or omissions from any Prospectus Supplement made in
reliance upon and in conformity with information relating to the Investor
furnished to the Company in writing by or on behalf of the Investor expressly
for use therein. The Company meets all of the requirements for the use of a
registration statement on Form S-3 pursuant to the Securities Act for the
offering and sale of the Securities contemplated by this Agreement, including,
to the extent applicable to the transactions contemplated by this Agreement,
those set forth in General Instruction I.B.6. of Form S-3, and the SEC has not
notified the Company of any objection to the use of the form of the Registration
Statement pursuant to Rule 401(g)(1) of the Securities Act. The Company hereby
confirms that, for so long as the Company is subject to General Instruction
I.B.6. of Form S-3, the Company shall not issue any shares of Common Stock
pursuant to this Agreement if such issuance would reasonably be expected to
result in non-compliance with General Instruction I.B.6. of Form S-3. The
Registration Statement, as of its effective date, meets the requirements set
forth in Rule 415(a)(1)(x) pursuant to the Securities Act. At the earliest time
after the filing of the Registration Statement that the Company or another
offering participant made a bona fide offer (within the meaning of Rule
164(h)(2) of the Securities Act) relating to any of the Securities, the Company
was not and is not an Ineligible Issuer (as defined in Rule 405 of the
Securities Act). The Company has not distributed any offering material in
connection with the offering and sale of any of the Securities, and, until the
Investor does not hold any of the Securities, shall not distribute any offering
material in connection with the offering and sale of any of the Securities, to
or by the Investor, in each case, other than the Registration Statement or any
amendment thereto, the Prospectus or any Prospectus Supplement required pursuant
to applicable law or the Transaction Documents. The Company has not made, and
agrees that unless it obtains the prior written consent of the Investor it will
not make, an offer relating to the Securities that would constitute a “free
writing prospectus” as defined in Rule 405 under the Securities Act. The Company
shall comply with the requirements of Rules 164 and 433 under the Securities Act
applicable to any such free writing prospectus consented to by the Investor,
including in respect of timely filing with the SEC, legending and record
keeping.

be listed on the TSX, shall comply in all respects with the Company’s reporting,
filing and other obligations under the bylaws or rules and regulations of the
TSX. Neither the Company nor any of its Subsidiaries shall take any action that

event later than the following Business Day, provide to the Investor copies of
any notices it receives from any Person regarding the continued eligibility of
the Common Stock for listing on the Principal Market or the TSX. The Company

(d) Limitation on Short Sales and Hedging Transactions. The Investor agrees
that, beginning on the date of this Agreement and ending on the date of
termination of this Agreement as provided in Section 11, the Investor and its
agents, representatives and affiliates shall not in any manner whatsoever enter
into or effect, directly or indirectly, any (i) “short sale” (as such term is
defined in Rule 200 of Regulation SHO of the Exchange Act) of the Common Stock
or (ii) hedging transaction, which establishes a net short position with respect
to the Common Stock.

(e) Issuance of Commitment Shares. In consideration for the Investor’s execution
and delivery of this Agreement, the Company shall cause the Transfer Agent to
issue, on the date of this Agreement, 651,819 shares of Common Stock (the
“Commitment Shares”) directly to the Investor electronically as DWAC Shares and
shall deliver to the Transfer Agent the Irrevocable Transfer Agent Instructions
(as defined below) with respect to the issuance of the Commitment Shares. For
the avoidance of doubt, all of the Commitment Shares shall be fully earned as of
the date of this Agreement, whether or not the Commencement shall occur or any
Purchase Shares are purchased by the Investor under this Agreement and
irrespective of any termination of this Agreement.

(f) Due Diligence; Non-Public Information. During the term of this Agreement,
the Investor shall have the right, from time to time, to perform reasonable due
diligence on the Company during the Company’s normal business hours. The Company
and its officers and employees shall provide information and reasonably
cooperate with the Investor in connection with any reasonable request by the
Investor related to the Investor's due diligence of the Company. Each party
hereto agrees not to disclose any Confidential Information of the other party to
any third party and shall not use the Confidential Information for any purpose
other than in connection with, or in furtherance of, the transactions
contemplated hereby. Each party hereto acknowledges that the Confidential
Information shall remain the property of the disclosing party and agrees that it
shall take all reasonable measures to protect the secrecy of any Confidential
Information disclosed by the other party. From and after the date of this
Agreement, the Company covenants and agrees that neither it nor any other Person
acting on its behalf will provide the Investor or its agents or counsel with any
information that the Company believes constitutes material non-public
information, unless a simultaneous public announcement thereof is made by the
Company in the manner contemplated by Regulation FD under the Exchange Act. In
the event of a breach of the foregoing covenant by the Company or any Person
acting on its behalf (as determined in the reasonable good faith judgment of the
Investor), in addition to any other remedy provided herein or in the other
Transaction Documents, the Investor shall have the right to make a public
disclosure, in the form of a press release, public advertisement or otherwise,
of such material, non-public information without the prior approval by the
Company; provided that the Company shall have failed to publicly disclose such
material, non-public information prior to such disclosure by the Investor. The
Investor shall not have any liability to the Company, any of its Subsidiaries,
or any of their respective directors, officers, employees, stockholders or
agents, for any such disclosure. The Company understands and confirms that the
Investor shall be relying on the foregoing covenants in effecting transactions
in securities of the Company.

(g) Purchase Records. The Investor and the Company shall each maintain records
showing the remaining Available Amount at any given time and the Purchase Dates,
and the Purchase Amounts and Accelerated Purchase Amounts for each respective

(h) Taxes. The Company shall pay any and all transfer, stamp or similar taxes
that may bepayable with respect to the issuance and delivery of any shares of
Common Stock to the Investor made under this Agreement.

(i) No Variable Rate Transactions. From the date hereof until the earlier of (x)
the Maturity Date and (y) 180 Business Days following the termination of this
Agreement in accordance with Section 11 hereof, 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 Stock or Common Stock Equivalents
for cash consideration (or a combination of units thereof) involving a Variable
Rate Transaction other than in connection with an Exempt Issuance. “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 shares of Common
Stock 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 shares of Common Stock 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 Stock (including, without limitation any “full ratchet” or
“weighted average” anti-dilution provisions, but excluding any adjustment for
any reorganization, recapitalization, non-cash dividend, stock split, reverse
stock split or similar transaction) or (ii) enters into any agreement,
including, but not limited to, an equity line of credit or at-the-market
offering, whereby the Company may sell securities at a future determined price.
“Exempt Issuance” means the issuance of (a) shares of Common Stock or options to
employees, officers, directors or vendors of the Company pursuant to any stock
or option plan duly adopted for such purpose, by the Board of Directors or a
majority of the members of a committee of directors established for such
purpose, (b) securities upon the exercise or exchange of or conversion of any
Securities issued hereunder and/or other securities exercisable or exchangeable
for or convertible into shares of Common Stock issued and outstanding on the
date of this Agreement, provided that such securities have not been amended
since the date of this Agreement to increase the number of such securities or to
decrease the exercise price, exchange price or conversion price of such
securities, and (c) securities issued pursuant to acquisitions or strategic
transactions approved by the Board of Directors or a majority of the members of
a committee of directors established for such purpose, which acquisitions or
strategic transactions can have a Variable Rate Transaction component, provided
that any such issuance shall only be to a Person (or to the equity holders of a
Person) which is, itself or through its subsidiaries, an operating company or an
asset in a business synergistic with the business of the Company and shall
provide to the Company additional benefits in addition to the investment of
funds, but shall not include a transaction in which the Company is issuing
securities primarily for the purpose of raising capital or to an entity whose
primary business is investing in securities. For twelve (12) Monthly Periods
beginning on the date hereof, the Company agrees that, prior to entering into
each and any definitive agreement for the sale directly or indirectly of any
debt, Common Stock or Common Stock Equivalents other than in connection with an
Exempt Issuance (a “Subsequent Transaction”), the Company shall provide notice
to the Investor (“Offering Notice”) not less than three (3) Business Days nor
more than five (5) Business Days prior to entering into any such Subsequent
Transaction, including the relevant terms and conditions of such Subsequent
Transaction, and the Investor shall have the right to participate on equivalent
terms and conditions in up to 10% of such Subsequent Transaction (the “Right of
Participation”) by delivering notice to the Company not later than two (2)
Business Days after receipt of the Offering Notice, which notice from Investor
shall indicate Investor’s intention to participate in the Subsequent Transaction
and the amount of its participation. In the event that the Investor does not
provide notice within the two (2) Business Day period and the Company does not
enter into such Subsequent Transaction within five (5) Business Days from the
Offering Notice, the Company shall again be required to provide an Offering
Notice as set forth herein. The Company shall deliver an Offering Notice for
each and any Subsequent Transaction and agrees that it shall not execute any
definitive documentation for any Subsequent Transaction whatsoever, unless it
has first complied with this Section 5(i). Notwithstanding anything to the
contrary in this Section 5(i) and unless otherwise agreed to by Investor, the
Company shall either confirm in writing to Investor that the transaction with
respect to the Subsequent Transaction has been abandoned or shall publicly
disclose its intention to enter into the Subsequent Transaction, in either case
in such a manner such that Investor will not be in possession of any material,
non-public information, by the fifth (5th) Business Day following delivery of
the Offering Notice. If by such fifth (5th) Business Day, no public disclosure
regarding a transaction with respect to the Subsequent Transaction has been
made, and no notice regarding the abandonment of such transaction has been
received by Investor, such transaction shall be deemed to have been abandoned
and Investor shall not be in possession of any material, non-public information
with respect to the Company or any of its Subsidiaries. If the Investor is in
possession of any information that is reasonably deemed to be material,
non-public information concerning the Company or any of its Subsidiaries during
such five (5) Business Day period, the Investor agrees to keep such information
confidential and shall not engage in transactions with respect to the Company’s
securities, and the Company agrees not to deliver any Purchase Notice to the
Investor, in each case during such five (5) Business Day (or shorter) period
that the Investor may be reasonably deemed to be in possession of material,
non-public information concerning the Company or any of its Subsidiaries. Should
the Company decide to pursue such transaction with respect to the Subsequent
Transaction, the Company shall provide Investor with another Offering Notice in
accordance with, and subject to, the terms of this Section 5(i) and Investor
will again have the Right of Participation set forth in this Section 5(i).

(j) Effective Registration Statement; Current Prospectus; Securities Law
Compliance. The Company shall use its reasonable best efforts to keep the
Registration Statement effective pursuant to Rule 415 promulgated under the
Securities Act, and to keep the Registration Statement and the Prospectus
current and available for issuances and sales of all of the Securities by the
Company to the Investor, and for the resale by the Investor, at all times until
the earlier of (i) the date on which the Investor shall have sold all the
Securities and no Available Amount remains under this Agreement and (ii) the
earlier of (A) 90 days following the Maturity Date and (B) 180 Business Days
following the termination of this Agreement in accordance with Section 11 hereof
(the "Registration Period"). Without limiting the generality of the foregoing,
during the Registration Period, the Company shall (a) take all action necessary
to cause the Common Stock to continue to be registered as a class of securities
under Sections 12(b) or 12(g) of the Exchange Act, shall comply with its
reporting and filing obligations under the Exchange Act, and shall not take any
action or file any document (whether or not permitted by the Exchange Act) to
terminate or suspend such registration or to terminate or suspend its reporting
and filing obligations under the Exchange Act, and (b) prepare and file with the
SEC, at the Company’s expense, such amendments (including, without limitation,
post-effective amendments) to the Registration Statement and such Prospectus
Supplements pursuant to Rule 424(b) under the Securities Act, in each case, as
may be necessary to keep the Registration Statement effective pursuant to Rule
415 promulgated under the Securities Act, and to keep the Registration Statement
and the Prospectus current and available for issuances and sales of all of the
Securities by the Company to the Investor, and for the resale of all of the
Securities by the Investor, at all times during the Registration Period (it
being hereby acknowledged and agreed that the Company shall prepare and file
with the SEC, at the Company’s expense, immediately prior to the third
anniversary of the initial effective date of the Registration Statement (the
“Renewal Date”), a new Registration Statement relating to the Securities, in a
form satisfactory to the Investor and its counsel, and, if such Registration
Statement is not an automatic shelf registration statement on Form S-3ASR, use
its reasonable best efforts to cause such Registration Statement to be declared
effective within 180 days after the Renewal Date). The Investor shall furnish to
the Company such information regarding itself, the Securities held by it and the
intended method of distribution thereof as shall be reasonably requested by the
Company in connection with the preparation and filing of any such amendment to
the Registration Statement (or new Registration Statement) or any such
Prospectus Supplement, and shall otherwise cooperate with the Company as
reasonably requested by the Company in connection with the preparation and
filing of any such amendment to the Registration Statement (or new Registration
Statement) or any such Prospectus Supplement. The Company shall comply with all
applicable federal, state and foreign securities laws in connection with the
offer, issuance and sale of the Securities contemplated by the Transaction
Documents. Without limiting the generality of the foregoing, neither the Company
nor any of its officers, directors or affiliates will take, directly or
indirectly, any action designed or intended to stabilize or manipulate the price
of any security of the Company, or which would reasonably be expected to cause
or result in, stabilization or manipulation of the price of any security of the
Company.

(k) Stop Orders. The Company shall advise the Investor promptly (but in no event
later than 24 hours) and shall confirm such advice in writing: (i) of the
Company’s receipt of notice of any request by the SEC for amendment of or a
supplement to the Registration Statement, the Prospectus, any Prospectus
Supplement or for any additional information; (ii) of the Company’s receipt of
notice of the issuance by the SEC of any stop order suspending the effectiveness
of the Registration Statement or prohibiting or suspending the use of the
Prospectus or any Prospectus Supplement, or of the Company’s receipt of any
notification of the suspension of qualification of the Securities for offering
or sale in any jurisdiction or the initiation or contemplated initiation of any
proceeding for such purpose; and (iii) of the Company becoming aware of the
happening of any event, which makes any statement of a material fact made in the
Registration Statement, the Prospectus or any Prospectus Supplement untrue or
which requires the making of any additions to or changes to the statements then
made in the Registration Statement, the Prospectus or any Prospectus Supplement
in order to state a material fact required by the Securities Act to be stated
therein or necessary in order to make the statements then made therein (in the
case of the Prospectus or any Prospectus Supplement, in light of the
circumstances under which they were made) not misleading, or of the necessity to
amend the Registration Statement or supplement the Prospectus or any Prospectus
Supplement to comply with the Securities Act or any other law. The Company shall
not be required to disclose to the Investor the substance or specific reasons of
any of the events set forth in clauses (i) through (iii) of the immediately
preceding sentence, but rather, shall only be required to disclose that the
event has occurred. The Company shall not deliver to the Investor any Purchase
Notice, and the Investor shall not be obligated to purchase any shares of Common
Stock under this Agreement and agrees not to resell any Securities covered by
the Registration Statement and the Prospectus through the Registration Statement
and the Prospectus, during the continuation or pendency of any of the events set
forth in clauses (i) through (iii) above in this Section 5(k). If at any time
the SEC shall issue any stop order suspending the effectiveness of the
Registration Statement or prohibiting or suspending the use of the Prospectus or
any Prospectus Supplement, the Company shall use its reasonable best efforts to
obtain the withdrawal of such order at the earliest possible time. The Company
shall make available to the Investor, without charge, a copy of any
correspondence from the SEC or the staff of the SEC to the Company or its
representatives relating to the Registration Statement or the Prospectus, as the
case may be.

(l) Amendments to Registration Statement; Prospectus Supplements. Except as
provided in this Agreement and other than periodic and current reports required
to be filed pursuant to the Exchange Act, the Company shall not file with the
SEC any amendment to the Registration Statement or any supplement to the Base
Prospectus that refers to the Investor, the Transaction Documents or the
transactions contemplated thereby (including, without limitation, any Prospectus
Supplement filed in connection with the transactions contemplated by the
Transaction Documents), in each case with respect to which (a) the Investor
shall not previously have been advised and afforded the opportunity to review
and comment thereon at least two (2) Business Days prior to filing with the SEC,
as the case may be, (b) the Company shall not have given due consideration to
any comments thereon received from the Investor or its counsel, or (c) the
Investor shall reasonably object, unless the Company reasonably has determined
that it is necessary to amend the Registration Statement or make any supplement
to the Prospectus to comply with the Securities Act or any other applicable law
or regulation, in which case the Company shall promptly (but in no event later
than 24 hours) so inform the Investor, the Investor shall be provided with a
reasonable opportunity to review and comment upon any disclosure referring to
the Investor, the Transaction Documents or the transactions contemplated
thereby, as applicable, and the Company shall expeditiously furnish to the
Investor a copy thereof. In addition, for so long as, in the reasonable opinion
of counsel for the Investor, the Prospectus is required to be delivered in
connection with any acquisition or sale of Securities by the Investor, the
Company shall not file any Prospectus Supplement with respect to the Securities
without furnishing to the Investor as many copies of such Prospectus Supplement,
together with the Prospectus, as the Investor may reasonably request.

of each Prospectus Supplement thereto) in accordance with the provisions of the
Securities Act and with the securities or “blue sky” laws of the jurisdictions
in which the Securities may be sold by the Investor, in connection with the
offering and sale of the Securities and for such period of time thereafter as
the Prospectus is required by the Securities Act to be delivered in connection
with sales of the Securities. The Company will make available to the Investor
upon reasonable request, and thereafter from time to time will furnish to the
Investor, as many copies of the Prospectus (and each Prospectus Supplement
thereto) as the Investor may reasonably request for the purposes contemplated by
the Securities Act within the time during which the Prospectus is required by
the Securities Act to be delivered in connection with sales of the Securities.
If during such period of time any event shall occur that in the reasonable
judgment of the Company and its counsel, or in the reasonable judgment of the
Investor and its counsel, is required to be set forth in the Registration
Statement, the Prospectus or any Prospectus Supplement or should be set forth
therein in order to make the statements made therein (in the case of the
Prospectus or any Prospectus Supplement, in light of the circumstances under
which they were made) not misleading, or if in the reasonable judgment of the
Company and its counsel, or in the reasonable judgment of the Investor and its
counsel, it is otherwise necessary to amend the Registration Statement or
supplement the Prospectus or any Prospectus Supplement to comply with the
Securities Act or any other applicable law or regulation, the Company shall
forthwith prepare and, subject to Section 5(l) above, file with the SEC an
appropriate amendment to the Registration Statement or an appropriate Prospectus
Supplement and in each case shall expeditiously furnish to the Investor, at the
Company’s expense, such amendment to the Registration Statement or such
Prospectus Supplement, as applicable, as may be necessary to reflect any such
change or to effect such compliance. The Company shall have no obligation to
separately advise the Investor of, or deliver copies to the Investor of, the SEC
Documents, all of which the Investor shall be deemed to have notice of.

(n) Integration. From and after the date of this Agreement, the Company shall
not sell, offer for sale or solicit offers to buy or otherwise negotiate in
respect of any security (as defined in Section 2 of the Securities Act) of the
Company that would be integrated with the offer or sale of the Securities such
that the rules or regulations of the Principal Market or the TSX would require
stockholder approval of this transaction prior to the closing of such other
transaction unless stockholder approval is obtained before the closing of such
subsequent transaction.

(o) No Canadian Offers or Sales by Investor. The Investor covenants and agrees
that it shall: (i) offer or sell any Securities that may be issued pursuant to
this Agreement only (A) in transactions executed on the Principal Market through
a registered broker-dealer located in the United States or (B) directly to third
Persons, none of whom, to the Investor’s knowledge following reasonable inquiry,
is a Person resident in Canada; (ii) not offer or sell any Securities that may
be issued pursuant to this Agreement on the TSX or directly to any third Person
whom, to the Investor’s knowledge following reasonable inquiry, is a Person
resident in Canada; (iii) deliver to the Company, promptly after the issuance of
Securities pursuant to this Agreement, a certificate stating that with respect
to any resales of such Securities by the Investor, the Investor shall comply
with clauses (i) and (ii) of this Section 5(o); and (iv) with respect to any
resale of such Securities by the Investor in any transaction referred to in
clause (i)(B) of this Section 5(o), the Investor shall include in each
confirmation slip delivered by the Investor to the purchaser of such Securities
a statement that it is the Investor’s understanding that such purchaser is not a
Person resident in Canada.

described in the Prospectus.

(q) Other Transactions. During the term of this Agreement, the Company shall not
enter into, announce or recommend to its stockholders any agreement, plan,

perform its obligations under the Transaction Documents, including, without
limitation, the obligation of the Company to deliver the Purchase Shares and the
Commitment Shares to the Investor in accordance with the terms of the
Transaction Documents.

(r) Required Filings Relating to Regular Purchases and Accelerated Purchases. To
the extent required under the Securities Act or under interpretations by the SEC
thereof, as promptly as practicable after the close of each of the Company’s
fiscal quarters (or on such other dates as required under the Securities Act or
under interpretations by the SEC thereof), the Company shall prepare a
prospectus supplement, which will set forth the number of Purchase Shares sold
to the Investor during such quarterly period (or other relevant period), the
purchase price for such Purchase Shares and the net proceeds received by the
Company from such sales, and shall file such prospectus supplement with the SEC
pursuant to Rule 424(b) under the Securities Act (and within the time periods
required by Rule 424(b) and Rule 430B under the Securities Act). If any such
prospectus supplement is not required to be filed under the Securities Act or
under interpretations by the SEC thereof, the Company shall disclose the
information referenced in the immediately preceding sentence in its annual
report on Form 10-K or its quarterly report on Form 10-Q (as applicable) in
respect of the quarterly period that ended immediately before the filing of such
report in which sales of Purchase Shares were made to the Investor under this
Agreement, and file such report with the SEC within the applicable time period
required by the Exchange Act. The Company shall not file any such prospectus
supplement or report containing disclosure relating to such sales of Purchase
Shares unless a copy of such disclosure has been submitted to the Investor a
reasonable period of time before the filing and the Investor has not reasonably
objected thereto (it being acknowledged and agreed that the Company need not
submit any portion of any Form 10-K or Form 10-Q other than the specific
disclosure relating to any sales of Purchase Shares). The Company shall also
furnish copies of all such prospectus supplements to each exchange or market in
the United States on which sales of the Purchase Shares may be made as may be
required by the rules or regulations of such exchange or market, if applicable.
For so long as the Common Stock is listed on the TSX, within 10 calendar days
after the end of each month during the term of this Agreement, the Company will,
in addition to filing a Form 1 with the TSX, separately e-mail to the TSX a
schedule indicating the aggregate number and price of Purchase Shares sold on a
daily basis during such month or as the TSX may otherwise direct, and will
provide, upon the request of the TSX, additional monthly reports of daily sales
of the Purchase Shares, which schedules and reports shall be submitted to the
TSX on a confidential, non-public basis.

In consideration of the Investor's execution and delivery of the Transaction
Documents and acquiring the Securities hereunder 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 Investor and all of its
affiliates, stockholders, officers, directors, employees and direct or indirect
investors and any of the foregoing person's agents or other representatives
(including, without limitation, those retained in connection with the
transactions contemplated by this Agreement) (collectively, the “Indemnitees”)
from and against any and all actions, causes of action, suits, claims, losses,
costs, penalties, fees, liabilities and damages, and expenses in connection
therewith (irrespective of whether any such 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 Indemnitee as a result of, or arising out of, or relating to: (a) any
misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, (b) any breach of any covenant,
agreement or obligation of the Company contained in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby,
(c) any cause of action, suit or claim brought or made against such Indemnitee
and arising out of or resulting from the execution, delivery, performance or
enforcement of the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, (d) any violation of the Securities
Act, the Exchange Act, U.S. state securities or “Blue Sky” laws or Canadian
securities laws, or the rules and regulations of the Principal Market or the TSX
in connection with the transactions contemplated by the Transaction Documents by
the Company or any of its Subsidiaries, affiliates, officers, directors or
employees, (e) any untrue statement or alleged untrue statement of a material
fact contained, or incorporated by reference, in the Registration Statement or
any amendment thereto or any omission or alleged omission to state therein, or
in any document incorporated by reference therein, a material fact required to
be stated therein or necessary to make the statements therein not misleading, or
(f) any untrue statement or alleged untrue statement of a material fact
contained, or incorporated by reference, in the Prospectus, or any omission or
alleged omission to state therein, or in any document incorporated by reference
therein, a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; provided, however, that (I) the indemnity contained in clause
(c) of this Section 9 shall not apply to any Indemnified Liabilities which
directly and primarily result from the gross negligence or willful misconduct of
the Indemnitee, (II) the indemnity contained in clauses (d), (e) and (f) of this
Section 9 shall not apply to any Indemnified Liabilities to the extent, but only
to the extent, arising out of or based upon any untrue statement or alleged
untrue statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
the Investor expressly for use in any Prospectus Supplement (it being hereby
acknowledged and agreed that the written information set forth on Exhibit D
attached hereto is the only written information furnished to the Company by or
on behalf of the Investor expressly for use in the Initial Prospectus
Supplement), if the Prospectus was timely made available by the Company to the
Investor pursuant to Section 5(l), (III) the indemnity contained in clauses (d),
(e) and (f) of this Section 9 shall not inure to the benefit of the Investor to
the extent such Indemnified Liabilities are based on a failure of the Investor
to deliver or to cause to be delivered the Prospectus made available by the
Company, if such Prospectus was timely made available by the Company pursuant to
Section 5(l), and if delivery of the Prospectus would have cured the defect
giving rise to such Indemnified Liabilities, and (IV) the indemnity in this
Section 9 shall not apply to amounts paid in settlement of any claim if such
settlement is effected without the prior written consent of the Company, which
consent shall not be unreasonably withheld, conditioned or delayed. 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. Payment under this indemnification shall be made within thirty
(30) days from the date Investor makes written request for it. A certificate
containing reasonable detail as to the amount of such indemnification submitted
to the Company by Investor shall be conclusive evidence, absent manifest error,
of the amount due from the Company to Investor. If any action shall be brought
against any Indemnitee in respect of which indemnity may be sought pursuant to
this Agreement, such Indemnitee shall promptly notify the Company in writing,
and the Company shall have the right to assume the defense thereof with counsel
of its own choosing reasonably acceptable to the Indemnitee. Any Indemnitee
shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Indemnitee, except to the extent that (i) the
employment thereof has been specifically authorized by the Company in writing,
(ii) the Company has failed after a reasonable period of time to assume such
defense and to employ counsel or (iii) in such action there is, in the
reasonable opinion of such separate counsel, a material conflict on any material
issue between the position of the Company and the position of such Indemnitee,
in which case the Company shall be responsible for the reasonable fees and
expenses of no more than one such separate counsel.

commences a voluntary case or any Person commences a proceeding against the

terminate without any liability or payment to the Company (except as set forth
below) without further action or notice by any Person.

and 8 above with respect to the Commencement, either the Company or the Investor
shall have the option to terminate this Agreement at the close of business on
such date or thereafter without liability of any party to any other party
(except as set forth below); provided, however, that the right to terminate this
Agreement under this Section 11(b) shall not be available to any party if such
party is then in breach of any covenant or agreement contained in this Agreement
or any representation or warranty of such party contained in this Agreement
fails to be true and correct such that the conditions set forth in Section 7(f)
or Section 8(d), as applicable, could not then be satisfied.

(c) At any time after the Commencement Date, the Company shall have the option

warranties and covenants of the Company and the Investor contained in Sections
3, 4, 5, and 6 hereof, the indemnification provisions set forth in Section 9
hereof and the agreements and covenants set forth in Sections 10, 11 and 12,
shall survive the Commencement and any termination of this Agreement. No
termination of this Agreement shall (i) affect the Company's or the Investor's
rights or obligations under this Agreement with respect to pending Regular
Purchases and Accelerated Purchases, and the Company and the Investor shall
complete their respective obligations with respect to any pending Regular

release the Company or the Investor from any liability for intentional
misrepresentation or willful breach of any of the Transaction Documents.

or proceeding by mailing a copy thereof to such party at the address for such

to review and comment upon, and shall have consulted with the Investor and its
counsel on the form and substance of, such press release or other public
disclosure. The Company agrees and acknowledges that its failure to fully comply
with this provision constitutes a Material Adverse Effect. The Company shall
have the right to approve before issuance any press release or any other public
disclosure made by or on behalf of the Investor whatsoever with respect to, in
any manner, the Company or any aspect of the Transaction Documents or the
transactions contemplated thereby; provided, however, that the Investor shall be
entitled, without the prior approval of the Company, to make any press release

applicable law and regulations, so long as prior to making any such press
release or other public disclosure the Investor and its counsel shall have
provided the Company and its counsel with a reasonable opportunity to review and

(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) Remedies, Other Obligations, Breaches and Injunctive Relief. The parties’
remedies provided in this Agreement, including, without limitation, the
Investor’s remedies provided in Section 9, shall be cumulative and in addition
to all other remedies available to the parties under this Agreement, at law or
in equity (including a decree of specific performance and/or other injunctive
relief), no remedy of any party contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein
shall limit any party’s right to pursue actual damages for any failure by the
other party to comply with the terms of this Agreement. The parties acknowledge
that a breach by any party of its obligations hereunder will cause irreparable
harm to the non-breaching party and that the remedy at law for any such breach
may be inadequate. The parties therefore agree that, in the event of any such
breach or threatened breach, the non-breaching party shall be entitled, in
addition to all other available remedies, to an injunction restraining any
breach, without the necessity of showing economic loss and without any bond or
other security being required.

attorney is retained to represent the Investor in any other proceedings
whatsoever in connection with this Agreement, then the Company shall pay to the
Investor, as incurred by the Investor, all reasonable costs and expenses
including attorneys' fees incurred in connection therewith, in addition to all
other amounts due hereunder.

(o) Waivers. No provision of this Agreement may be waived other than in a
written instrument signed by the party against whom enforcement of such waiver
is sought. No failure or delay in the exercise of any power, right or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privilege.
