EXERCISE OF THE WARRANT



3.1           Method
of Exercise of the Warrant. The right to purchase Common Shares conferred by the Warrant Certificate may be exercised, prior
to the Expiry Time, by the holder delivering to the Company (whether via facsimile or otherwise) a duly completed and executed
subscription form substantially in the form attached hereto as Schedule “B” (the “Subscription Form”)
and a certified check, bank draft, wire transfer or a money order payable to or to the order of the Company, for the Exercise Price
applicable at the time of exercise in respect of the Common Shares subscribed for in lawful money of the United States, to the
Company.



3.2           Effective
Date of Exercise of the Warrant. This Warrant Certificate together with such Subscription Form, certified check, bank draft,
wire transfer or a money order will be deemed to be exercised only upon actual receipt thereof by the Company as set out above
(the “Exercise Date”).



3.3           Effect
of Exercise of the Warrant.



(a)          Upon
delivery of the Subscription Form and payment as aforesaid the Common Shares so subscribed for shall be issued as fully paid and
non-assessable shares and the holder shall become the holder of record of such Common Shares on the date of such delivery and such
payment; and



(b)          Within
five business days after delivery and payment as aforesaid, the Company shall forthwith cause the issuance to the holder of a certificate

for Less than Entitlement. The holder may subscribe for and purchase a number of Common Shares less than the number which it
is entitled to purchase pursuant to this Warrant Certificate. Execution and delivery of a Subscription Form with respect to less

of a new Warrant evidencing the right to purchase the remaining number of shares underlying this Warrant. Execution and delivery
of a Subscription Form for all of the then- remaining shares underlying this Warrant shall have the same effect as cancellation
of the original of this Warrant after delivery of the shares underlying this Warrant in accordance with the terms hereof.

of the Warrant. After the Expiry Time all rights hereunder shall wholly cease and terminate and the Warrant shall be void and

of this Warrant shall bear a legend in substantially the following forms:



(a)



“THE

AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER
THE 1933 ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THIS CERTIFICATE THAT REGISTRATION IS NOT REQUIRED UNDER THE
1933 ACT.”



(b)



“Unless permitted under
securities legislation, the holder of the securities shall not trade the securities before January 21, 2014.”



“Without prior written approval
of the TSX Venture Exchange and compliance with all applicable securities legislation, the securities represented by this certificate
may not be sold, transferred, hypothecated or otherwise traded on or through the facilities of the TSX Venture Exchange or otherwise
in Canada or to or for the benefit of a Canadian resident until January 21, 2014.”



ARTICLE 4

ADJUSTMENTS



4.1           Adjustments.
The number of Common Shares purchasable upon the exercise of each Warrant and the Exercise Price shall be subject to adjustment
as follows:



(a)          in
the event the Company shall:



(i)          pay
a dividend in Common Shares or make a distribution in CommonShares;



(ii)         subdivide
its outstanding Common Shares;



(iii)        combine
its outstanding Common Shares into a smaller number of Common Shares; or



(iv)        issue
by reclassification of its Common Shares other securities of the Company (including any such reclassification in connection with
a consolidation, merger, amalgamation or other combination in which the Company is the surviving corporation);



A-4







the number of Common Shares (or
other securities) purchasable upon exercise of each Warrant immediately prior thereto shall be adjusted so that the Warrantholder
shall be entitled to receive the kind and number of Common Shares or other securities of the Company which it would have owned
or have been entitled to receive after the happening of any of the events described above, had such Warrant been exercised immediately
prior to the happening of such event or any record date with respect thereto. An adjustment made pursuant to this subsection (a)
shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.



(b)          In
case the Company shall issue rights, options or warrants to all or substantially all holders of its outstanding Common Shares,
without any charge to such holders, entitling them (for a period within 45 days after the record date mentioned below) to subscribe
for or purchase Common Shares at a price per share which is lower than 95% of the current market price at the record date mentioned
below (as determined in accordance with subsection (d) below), the number of Common Shares thereafter purchasable upon the exercise
of each Warrant shall be determined by multiplying the number of Common Shares theretofore purchasable upon exercise of each Warrant
by a fraction, of which the numerator shall be the number of Common Shares outstanding on the date of issuance of such rights,
options or warrants plus the number of additional Common Shares offered for subscription or purchase, and of which the denominator
shall be the number of Common Shares outstanding on the date of issuance of such rights, options or warrants plus the number of
shares which the aggregate offering price of the total number of Common Shares so offered would purchase at the current market
price per Common Share at such record date. Such adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective immediately after the record date for the determination of shareholders entitled to receive such rights,
options or warrants.



(c)          In
case the Company shall distribute to all or substantially all holders of its Common Shares evidences of its indebtedness or assets
(excluding cash dividends or distributions payable out of consolidated earnings or earned surplus and dividends or distributions
referred to in subsection (a) above or in subsection (d) below or rights, options or warrants, or convertible or exchangeable securities
containing the right to subscribe for or purchase Common Shares (excluding those referred to in subsection (b) above)), then in
each case the number of Common Shares thereafter purchasable upon the exercise of each Warrant shall be determined by multiplying
the number of Common Shares theretofore purchasable upon the exercise of each Warrant by a fraction, of which the numerator shall
be the then current market price per Common Share (as determined in accordance with subsection (d) below) on the date of such distribution,
and of which the denominator shall be the then current market price per Common Share less the then fair value (as determined by
the board of directors of the Company, acting reasonably) of the portion of the assets or evidences of indebtedness so distributed
or of such subscription rights, options or warrants, or of such convertible or exchangeable securities applicable to one Common
Share. Such adjustment shall be made whenever any such distribution is made, and shall become effective on the date of distribution
retroactive to the record date for the determination of shareholders entitled to receive such distribution.



In the event
of the distribution by the Company to all or substantially all of the holders of its Common Shares of shares of a subsidiary or
securities convertible or exercisable for such shares, then in lieu of an adjustment in the number of Common Shares purchasable
upon the exercise of each Warrant, the Warrantholder of each Warrant, upon the exercise thereof, shall receive from the Company,
such subsidiary or both, as the Company shall reasonably determine, the shares or other securities to which such Warrantholder
would have been entitled if such Warrantholder had exercised such Warrant immediately prior thereto, all subject to further adjustment
as provided in this Section 4.1 provided, however, that no adjustment in respect of dividends or interest on such shares or other
securities shall be made during the term of a Warrant or upon the exercise of a Warrant.



A-5







(d)          For
the purpose of any computation under subsections (b) and (c) of this Section 4.1, the current market price per Common Share at
any date shall be the weighted average price per Common Share for twenty-five (25) consecutive trading days, commencing not more
than 45 trading days before such date on the stock exchange on which the Common Shares are then traded; provided if the Common
Shares are then traded on more than one stock exchange, then on the stock exchange on which the largest volume of Common Shares
were traded during such twenty-five(25) consecutive trading day period. The weighted average price per Common Share shall
be determined by dividing the aggregate sale price of all Common Shares sold on such exchange or market, as the case may be, during
the said twenty-five (25) consecutive trading days by the total number of shares so sold. For purposes of this subsection (d),
trading day means, with respect to a stock exchange, a day on which such exchange is open for the transaction of business. Should
the Common Shares not be listed on any stock exchange the current market price per Common Share at any date shall be determined
by the board of directors of the Company, acting reasonably.



(e)          In
any case in which this Article 4 shall require that any adjustment in the Exercise Price be made effective immediately after a
record date for a specified event, the Company may elect to defer until the occurrence of the event the issuance, to the holder
of any Warrant exercised after that record date, of the Common Shares and other shares of the Company, if any, issuable upon the
exercise of the Warrant over and above the Common Shares and other shares of the Company; provided, however, that the Company shall
deliver to the holder an appropriate instrument evidencing the holder’s right to receive such additional shares upon the
occurrence of the event requiring such adjustment.



(f)          No
adjustment in the number of Common Shares purchasable hereunder shall be required unless such adjustment would require an increase
or decrease of at least one percent (1%) in the number of Common Shares purchasable upon the exercise of each Warrant; provided,
however, that any adjustments which by reason of this subsection (f) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations shall be made to the nearest one-hundredth of a share.



(g)          Wherever
the number of Common Shares purchasable upon the exercise of each Warrant is adjusted, as herein provided, the Exercise Price payable
upon exercise of each Warrant shall be adjusted by multiplying such Exercise Price immediately prior to such adjustment by a fraction,
of which the numerator shall be the number of Common Shares purchasable upon the exercise of such Warrant immediately prior to
such adjustment, and of which the denominator shall be the number of Common Shares purchasable immediately thereafter.



(h)          No
adjustment in the number of Common Shares purchasable upon the exercise of each Warrant need be made under subsections (b) and
(c) if, the Company issues or distributes to the Warrantholder the rights, options, warrants, or convertible or exchangeable securities,
or evidences of indebtedness or assets referred to in those subsections which the Warrantholder would have been entitled to receive
had the Warrants been exercised prior to the happening of such event or the record date with respect thereto.



A-6







(i)          In
the event that at any time, as a result of an adjustment made pursuant to subsection (a) above, the Warrantholder shall
become entitled to purchase any securities of theCompany other than Common Shares, thereafter the number of such
other shares so purchasable upon exercise of each Warrant and the Exercise Price of such shares shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to
the Common Shares contained in subsections (a) through (h), inclusive, above, and the provisions of sections 4.2 through 4.4,
inclusive, of this Article 4 with respect to the Common Shares, shall apply on like terms to any such other securities.



(j)          Upon
the expiration of any rights, options, warrants or conversion or exchange privileges, if any thereof shall not have been exercised,
the Exercise Price and the number of Common Shares purchasable upon the exercise of each Warrant shall, upon such expiration, be
readjusted and shall thereafter be such as it would have been had it been originally adjusted (or had the original adjustment not
been required, as the case may be) as if:



(i)          the
only Common Shares so issued were the Common Shares, if any, actually issued or sold upon the exercise of such rights, options,
warrants or conversion or exchange rights; and



(ii)         such
Common Shares, if any, were issued or sold for the consideration actually received by the Company upon such exercise plus the aggregate
consideration, if any, actually received by the Company for the issuance, sale or grant of all such rights, options, warrants or
conversion or exchange rights whether or not exercised;



provided further, that no such
readjustment shall have the effect of increasing the Exercise Price or decreasing the number of Common Shares purchasable upon
the exercise of each Warrant by an amount in excess of the amount of the adjustment initially made with respect to the issuance,
sale or grant of such rights, options, warrants or conversion or exchange rights.



4.2           Voluntary
Adjustment by the Company. Subject to requisite Exchange approval, the Company may, at its option, at any time during the term
of the Warrants, reduce the then current Exercise Price to any amount deemed appropriate by the Board of Directors of the Company.



4.3           Notice
of Adjustment. Whenever the number of Common Shares purchasable upon the exercise of each Warrant or the Exercise Price of
such Common Shares is adjusted, as herein provided, the Company shall promptly send to the Warrantholder by first class mail, postage
prepaid, notice of such adjustment or adjustments.



4.4           No
Adjustment for Dividends. Except as provided in Section 4.1 of this Article 4, no adjustment in respect of any dividends shall
be made during the term of a Warrant or upon the exercise of a Warrant.



4.5           Preservation
of Purchase Rights Upon Merger, Consolidation, etc. In connection with any consolidation of the Company with, or amalgamation
or merger of the Company with or into, another corporation (including, without limitation, pursuant to a “takeover bid”,
“tender offer” or other acquisition of all or substantially all of the outstanding Common Shares) or in case of any
sale, transfer or lease to another corporation of all or substantially all the property of the Company, the Company or such successor
or purchasing corporation, as the case may be, shall execute with the Warrantholder an agreement that the Warrantholder shall have
the right thereafter, upon payment of the Exercise Price in effect immediately prior to such action, to purchase upon exercise
of each Warrant the kind and amount of shares and other securities and property which it would have ownedor have been entitled
to receive after the happening of such consolidation, amalgamation, merger, sale, transfer or lease had such Warrant been exercised
immediately prior to such action, and the Warrantholder shall be bound to accept such shares and other securities and property
in lieu of the Common Shares to which it was previously entitled; provided, however, that no adjustment in respect of dividends,
interest or other income on or from such shares or other securities and property shall be made during the term of a Warrant or
upon the exercise of a Warrant. Any such agreement shall provide for adjustments, which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Schedule “A”. The provisions of this Article 4 shall similarly
apply to successive consolidations, mergers, amalgamation, sales, transfers or leases.



A-7







4.6           Determination
of Adjustments. If any questions shall at any time arise with respect to the Exercise Price, such question shall be conclusively
determined by the Company’s Auditors, or, if they decline to so act, any other firm of Chartered Accountants, in Vancouver,
British Columbia, that the Company may designate and the Warrantholder, acting reasonably, may approve, and who shall have access
to all appropriate records and such determination shall be binding upon the Company and the holder.

8.3           Disposition
of Shares and Warrant.



(a)          The
Holder hereby acknowledges that: (i) this Warrant and any Common Shares issuable upon exercise of the Warrant have not been
registered (A) under the 1933 Act on the ground that the issuance of this Warrant is exempt from registration under Section
4(a)(2) of the 1933 Act as not involving any public offering, or (B) under any applicable state securities law because the
issuance of this Warrant does not involve any public offering; and (ii) that the Company’s reliance on the registration
exemption under Section 4(a)(2) of the 1933 Act and under applicable state securities laws is predicated in part on the
representations hereby made to the Company by the Warrantholder. The Warrantholder represents and warrants that he, she or it
is acquiring this Warrant and will acquire Common Shares issuable upon exercise of the Warrant for investment for his, her or
its own account, with no present intention of dividing his, her or its participation with others or reselling or otherwise
distributing this Warrant or Common Shares issuable upon exercise of the Warrant.



A-9







(b)          The
Warrantholder hereby agrees that he, she or it will not sell, transfer, pledge or otherwise dispose of (collectively, “Transfer”) all or any part of this Warrant and/or Common Shares issuable upon exercise of the Warrant unless and until he,
she or it shall have first obtained an opinion, reasonably satisfactory to counsel for the Company, of counsel (competent in securities
matters, selected by the Warrantholder and reasonably satisfactory to the Company) to the effect that the proposed Transfer may
be made without registration under the 1933 Act and without registration or qualification under any United States state law.



(c)          If,
at the time of issuance of Common Shares issuable upon exercise of the Warrant, no registration statement is in effect with respect
to such shares under applicable provisions of the 1933 Act and the Common Shares issuable upon exercise of the Warrant may not
be sold pursuant to Rule 144 of the 1933 Act, the Company may, at its election, require that any stock certificate evidencing Common
Shares issuable upon exercise of the Warrant shall bear the legend reading substantially as set forth in paragraph 3.6(a) above.
In addition, so long as the foregoing legend may remain on any stock certificate evidencing Common Shares issuable upon exercise
of the Warrant, the Company may maintain appropriate “stop transfer” orders with respect to such certificates and the
shares represented thereby on its books and records and with those to whom it may delegate registrar and transfer functions.



8.4           Transfer
of Warrants. Subject to applicable securities legislation (including, but not limited to, the 1933 Act) and the rules, policies,
