1 - EXERCISE OF WARRANTS

 

	 	1.1	Election to Purchase

 

The
rights evidenced by this Warrant Certificate may be exercised by the Holder in whole or in part at any time commencing on the date
hereof and continuing up to the Time of Expiry and in accordance with the provisions hereof by delivery of an election to exercise
in substantially the form attached hereto as Exhibit “1” (“Election to Exercise”),
properly completed and executed, together with payment of the Exercise Price for the number of Shares specified in the Election
to Exercise to the office of the Corporation at 828 Richmond Street West, Toronto, Ontario, M6J 1C9

event that the rights evidenced by this Warrant Certificate are exercised in part, the Corporation shall, contemporaneously with

    	 	 -2-	 

    

 

		1.2	Exercise

 

The Corporation shall, as soon as possible
following receipt of a duly executed Election to Exercise and the Exercise Price for the number of Shares specified in the Election

to the Holder, registered in such name or names as the Holder may direct or if no such direction has been given, in the name of
the Holder, certificates for the number of Shares specified in the Election to Exercise. To the extent permitted by law, such exercise
shall be deemed to have been effected as of the close of business on the Exercise Date, and at such time the rights of the Holder
with respect to the number of Warrants which have been exercised as such shall cease, and the person or persons in whose name or
names any certificate or certificates for Shares shall then be issuable upon such exercise shall be deemed to have become the holder
or holders of record of the Shares represented thereby.

that the Holder is entitled to receive on the exercise or partial exercise thereof a fraction of a Share, such right may be exercised
only in respect of such fraction in combination with another Warrant or other Warrants which in the aggregate entitle the Holder
to receive a whole number of Shares.

 

(b)   If the Holder
is not able to, or elects not to, combine Warrants so as to be entitled to acquire a whole number of Shares, the Holder shall not
be entitled to any compensation or other right in lieu of fractional Shares, as the case may be.

(a)   “Adjustment
Period” means the period commencing on the date hereof and ending at the Time of Expiry; and

		2.2	Adjustments

 

The
Exercise Price and the number of Shares issuable to the Holder upon exercise of the Warrants shall be subject to adjustment from
time to time in the events and in the manner provided as follows:

 

(a)   If at any time
during the Adjustment Period the Corporation shall:

 

		(i)	fix a record date for the issue of, or issue, Shares to the holders of all or substantially all
of the outstanding Shares by way of a stock dividend;

 

		(ii)	fix a record date for the distribution to, or make a distribution to, the holders of all or substantially
all of the Shares payable in Shares or securities exchangeable for or convertible into Shares;

 

		(iii)	subdivide the outstanding Shares into a greater number of Shares; or

 

		(iv)	consolidate the outstanding Shares into a lesser number of Shares,

 

(any of such events in subclauses
(i), (ii), (ii) and (iv) above being herein called a “Common Share Reorganization”), the Exercise Price shall
be adjusted on the earlier of the record date on which holders of Shares are determined for the purposes of the Common Share Reorganization
and the effective date of the Common Share Reorganization to the amount determined by multiplying the Exercise Price in effect
immediately prior to such record date or effective date, as the case may be, by a fraction:

 

		(A)	the numerator of which shall be the number of Shares outstanding on such record date or effective
date before giving effect to such Common Share Reorganization; and

 

     

    	 	 -4-	 

    

 

 

		(B)	the denominator of which shall be the number of Shares which will be outstanding immediately after
giving effect to such Common Share Reorganization (including in the case of a distribution of securities exchangeable for or convertible
into Shares, the number of Shares that would be outstanding had such securities all been exchanged for or converted into Shares
on such date).

 

To the extent that any adjustment
in the Exercise Price occurs pursuant to this Section 2.2(a) as a result of the fixing by the Corporation of a record date for
the distribution of securities exchangeable for or convertible into Shares, the Exercise Price shall be readjusted immediately
after the expiry of any relevant exchange or conversion right to the Exercise Price which would then be in effect based upon the
number of Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the
expiry of any further such right.

 

(b)   If at any time
during the Adjustment Period there shall occur:

 

		(i)	a reclassification or redesignation of the Shares, any change of the Shares into other shares or
securities or any other capital reorganization involving the Shares other than a Common Share Reorganization;

 

		(ii)	a consolidation, amalgamation or merger of the Corporation with or into any other body corporate
which results in a reclassification or redesignation of the Shares or a change of the Shares into other shares or securities; or

 

		(iii)	the transfer of the undertaking or assets of the Corporation as an entirety or substantially as
an entirety to another corporation or entity,

 

(any of such events being herein

of Shares to which the Holder was theretofore entitled upon the exercise of the Warrants, the kind and aggregate number of shares

as a result of the Capital Reorganization if, on the effective date thereof, the Holder had been the registered holder of the number
of Shares to which the Holder was theretofore entitled to purchase or receive upon the exercise of the Warrants. If necessary,
as a result of any Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Warrant
Certificate with respect to the rights and interest thereafter of the Holder to the end that the provisions of this Warrant Certificate
shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other
securities or property thereafter deliverable upon the exercise of this Warrant Certificate.

(c)   If at any time
during the Adjustment Period any adjustment or readjustment in the Exercise Price shall occur pursuant to the provisions of Sections
2.2(a) hereof, then the number of Shares purchasable upon the subsequent exercise of this Warrant shall be simultaneously adjusted
or readjusted, as the case may be, by multiplying the number of Shares purchasable upon the exercise of the Warrants immediately
prior to such adjustment or readjustment by a fraction which shall be the reciprocal of the fraction used in the adjustment or
readjustment of the Exercise Price.

 

		2.3	Rules

 

The
following rules and procedures shall be applicable to adjustments made pursuant to Section 2.2 of this Warrant Certificate.

 

(a)   Subject to the
following provisions of this Section 2.3, any adjustment made pursuant to Section 2.2 hereof shall be made successively whenever
an event referred to therein shall occur.

 

(b)   No adjustment
in the Exercise Price shall be required unless the adjustment would result in a change of at least 1% in the Exercise Price then
in effect and no adjustment shall be made in the number of Shares purchasable or issuable on the exercise of the Warrants unless
it would result in a change of at least one one-hundredth of a Share provided, however, that any adjustments which except for the
provisions of this Section 2.3(b) would otherwise have been required to be made shall be carried forward and taken into account
in any subsequent adjustment.

 

(c)   No adjustment
in the Exercise Price or in the number or kind of securities purchasable on the exercise of this Warrant shall be made in respect
of any event described in Article 2 hereof if the Holder is entitled to participate in such event on the same terms mutatis
mutandis as if the Holder had exercised the Warrants prior to or on the record date or effective date, as the case may be,
of such event.

 

(d)   If the Corporation
sets a record date to determine holders of Shares for the purpose of entitling such holders to receive any dividend or distribution,
shall thereafter and before the distribution to such holders of any such dividend or distribution, legally abandon its plan to
pay or deliver such dividend or distribution, no adjustment in the Exercise Price of the number of Shares purchasable upon the
exercise of the Warrants shall be required by reason of the setting of such record date.

 

     

    	 	 -6-	 

    

  

(e)   In any case in
which this Warrant Certificate shall require that an adjustment shall become effective immediately after a record date for an event
referred to in Section 2.2 hereof, the Corporation may defer until the occurrence of such event:

 

		(i)	issuing to the Holder to the extent that the Warrants are exercised after such record date and
before the occurrence of such event, the additional Shares issuable upon such exercise by reason of the adjustment required by
such event; and

 

		(ii)	delivering to the Holder any distribution declared with respect to such additional Shares after
such record date and before such event,

 

provided, however, that the Corporation
shall deliver to the Holder an appropriate instrument evidencing the right of the Holder, upon the occurrence of the event requiring
the adjustment, to an adjustment in the Exercise Price or the number of Shares purchasable upon the exercise of the Warrants and
to such distribution declared with respect to any such additional Shares issuable on this exercise of the Warrants.

 

(f)   If a dispute shall
at any time arise with respect to any adjustment of the Exercise Price or the number of Shares purchasable pursuant to this Warrant
Certificate, such dispute shall be conclusively determined by the auditors of the Corporation or if they are unable or unwilling
to act by such other firm of independent chartered accountants as may be selected by the directors.

                                         of Actions

 

As
a condition precedent to the taking of any action which would require an adjustment pursuant to Section 2.2 hereof, the Corporation
shall take any action which may, in the opinion of counsel, be necessary in order that the Corporation may validly and legally
issue as fully paid and non-assessable shares all of the Shares which the Holder is entitled to receive in accordance with the
provisions of this Warrant Certificate.

 

		2.5	Notice

 

At
least five days prior to any record date or effective date, as the case may be, for any event which requires or might require an
adjustment in any of the rights of the Holder under this Warrant Certificate, including the Exercise Price and the number of Shares
which are purchasable under this Warrant Certificate, the Corporation shall deliver to the Holder a certificate of the Corporation
specifying the particulars of such event and, if determinable, the required adjustment and the calculation of such adjustment.
In case any adjustment for which a notice in this Section 2.5 has been given is not then determinable, the Corporation shall promptly
after such adjustment is determinable deliver to the Holder a Certificate providing the calculation of such adjustment. The Corporation
hereby covenants and agrees that the register of transfers and share transfer books for the Shares will be open and that the Corporation
will not take any action which might deprive the Holder of the opportunity of exercising the rights of subscription contained in
this Warrant Certificate during such five day period.

time to time in the events and in the manner provided as follows:

 

(a)   If at any time
during the Adjustment Period the Corporation shall:

 

		(i)	fix a record date for the issue of, or issue, Shares to the holders of all or substantially all
of the outstanding Shares by way of a stock dividend;

 

		(ii)	fix a record date for the distribution to, or make a distribution to, the holders of all or substantially
all of the Shares payable in Shares or securities exchangeable for or convertible into Shares;

 

		(iii)	subdivide the outstanding Shares into a greater number of Shares; or

 

		(iv)	consolidate the outstanding Shares into a lesser number of Shares,

 

(any of such events in subclauses
(i), (ii), (ii) and (iv) above being herein called a “Common Share Reorganization”), the Exercise Price shall
be adjusted on the earlier of the record date on which holders of Shares are determined for the purposes of the Common Share Reorganization

date before giving effect to such Common Share Reorganization; and

To the extent that any adjustment

the distribution of securities exchangeable for or convertible into Shares, the Exercise Price shall be readjusted immediately
after the expiry of any relevant exchange or conversion right to the Exercise Price which would then be in effect based upon the
number of Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the
expiry of any further such right.

 

(b)   If at any time
during the Adjustment Period there shall occur:

 

		(i)	a reclassification or redesignation of the Shares, any change of the Shares into other shares or
securities or any other capital reorganization involving the Shares other than a Common Share Reorganization;

which results in a reclassification or redesignation of the Shares or a change of the Shares into other shares or securities; or

an entirety to another corporation or entity,

of Shares to which the Holder was theretofore entitled upon the exercise of the Warrants, the kind and aggregate number of shares

as a result of any Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Warrant
Certificate with respect to the rights and interest thereafter of the Holder to the end that the provisions of this Warrant Certificate
shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other
securities or property thereafter deliverable upon the exercise of this Warrant Certificate.

or readjusted, as the case may be, by multiplying the number of Shares purchasable upon the exercise of the Warrants immediately
prior to such adjustment or readjustment by a fraction which shall be the reciprocal of the fraction used in the adjustment or
readjustment of the Exercise Price.

 

		2.3	Rules

 

The
following rules and procedures shall be applicable to adjustments made pursuant to Section 2.2 of this Warrant Certificate.

 

(a)   Subject to the
following provisions of this Section 2.3, any adjustment made pursuant to Section 2.2 hereof shall be made successively whenever
an event referred to therein shall occur.

 

(b)   No adjustment
in the Exercise Price shall be required unless the adjustment would result in a change of at least 1% in the Exercise Price then
in effect and no adjustment shall be made in the number of Shares purchasable or issuable on the exercise of the Warrants unless
it would result in a change of at least one one-hundredth of a Share provided, however, that any adjustments which except for the
provisions of this Section 2.3(b) would otherwise have been required to be made shall be carried forward and taken into account
in any subsequent adjustment.

 

(c)   No adjustment
in the Exercise Price or in the number or kind of securities purchasable on the exercise of this Warrant shall be made in respect
of any event described in Article 2 hereof if the Holder is entitled to participate in such event on the same terms mutatis
mutandis as if the Holder had exercised the Warrants prior to or on the record date or effective date, as the case may be,
of such event.

(d)   If the Corporation
sets a record date to determine holders of Shares for the purpose of entitling such holders to receive any dividend or distribution
and shall thereafter and before the distribution to such holders of any such dividend, distribution legally abandon its plan to
pay or deliver such dividend or distribution, no adjustment in the Exercise Price of the number of Shares purchasable upon the
exercise of the Warrants shall be required by reason of the setting of such record date.

 

(e)   In any case in
which this Warrant Certificate shall require that an adjustment shall become effective immediately after a record date for an event
referred to in Section 2.2 hereof, the Corporation may defer until the occurrence of such event:

 

		(i)	issuing to the Holder to the extent that the Warrants are exercised after such record date and
before the occurrence of such event, the additional Shares issuable upon such exercise by reason of the adjustment required by
such event; and

 

		(ii)	delivering to the Holder any distribution declared with respect to such additional Shares after
such record date and before such event,

 

provided, however, that the Corporation
shall deliver to the Holder an appropriate instrument evidencing the right of the Holder, upon the occurrence of the event requiring
the adjustment, to an adjustment in the Exercise Price or the number of Shares purchasable upon the exercise of the Warrants and
to such distribution declared with respect to any such additional Shares issuable on this exercise of the Warrants.

 

(f)   If a dispute shall
at any time arise with respect to any adjustment of the Exercise Price or the number of Shares purchasable pursuant to this Warrant
Certificate, such dispute shall be conclusively determined by the auditors of the Corporation or if they are unable or unwilling
to act by such other firm of independent chartered accountants as may be selected by the directors.
