Article 3

CONVERSION OF DEBENTURE


3.1             
Conversion Privilege and Conversion Price


Subject to and upon
compliance with the provisions of this Article 3, the Debenture or any portion of the Principal Sum which is $1,000 or an
integral multiple of $1,000 may, at the option of the Holder, at any time up to, but not after, the close of business on the last
Business Day immediately prior to the Maturity Date be converted into Common Shares at the Conversion Price.


3.2             
Conversion Procedure


		(1)	In order to exercise the conversion privilege, the Holder will provide written notice (the "Conversion
Notice") to the Corporation stating that the Holder elects to convert such Debenture or a stated portion of the Principal
Sum, constituting an integral multiple of $1,000, into Common Shares. The Conversion Notice shall constitute a contract between
the Holder and the Corporation. The Holder upon conversion agrees that the Corporation will be automatically released of all liability
thereon or from all liability with respect to that portion of the Principal Sum converted, as the case may be. The date of the
Conversion Notice is herein referred to as the "Date of Conversion" of such Debenture.



		(2)	As promptly as practicable after the Date of Conversion, the Corporation shall issue or cause to
be issued and deliver to the Holder certificate(s) in the name of the Holder of the Debenture for the number of Common Shares deliverable
upon the conversion of such Debenture (or specified portion thereof). Such conversion shall be deemed to have been effected immediately
prior to the close of business on the Date of Conversion.



		(3)	The Common Shares issued upon such conversion shall rank only in respect of dividends declared
in favour of shareholders of record on and after the Date of Conversion or
such later date as such holder shall become the holder of record of such Common Shares pursuant to this Section 3.2.










    	 	8	 



     


    
		(4)	Upon surrender to the Corporation of any Debenture which is to be converted in part only, the Holder
thereof shall be entitled to receive, without expense to the Holder, one or more Debentures for the unconverted portion of the
Principal Sum of the Debenture so surrendered.



3.3             
No Fractional Shares


Notwithstanding
anything herein contained, the Corporation shall in no case be required to issue fractional Common Shares upon the conversion of
any Debenture. If any fractional interest in a Common Share would, except for the provisions of this Section 3.3, be deliverable
upon the conversion of any Debenture, the aggregate number of Common Shares to which such holder shall be entitled shall be rounded
down to the nearest whole number if the fraction is less than 0.5 and rounded up to the nearest whole number if the fraction is
0.5 or greater.


3.4             
Adjustment to Conversion Price


The Conversion Price
shall be subject to adjustment from time to time as follows:


		(1)	If and whenever at any time the outstanding Common Shares of the Corporation shall be subdivided,
redivided or changed into a greater or consolidated into a lesser number of shares or reclassified into different shares, the Holder
who has not exercised his right of conversion prior to the effective date of such event shall be entitled to receive and shall
accept, upon the exercise of such right at any time on such effective date or thereafter, in lieu of the number of Common Shares
to which he was theretofore entitled upon conversion, the aggregate number of Common Shares of the Corporation that such Debentureholder
would have been entitled to receive as a result of any such event had he been the registered holder of the number of common shares
to which he was theretofore entitled upon conversion.



		(2)	In case the Corporation shall fix a record date for the issuance of additional Common Shares (or
securities convertible into additional Shares) to the holders of all or substantially all of its outstanding Common Shares by way
of a stock dividend or otherwise (other than an issue of additional Common Shares to holders of Common Shares who have elected
to receive dividends in Common Shares in lieu of receiving cash dividends paid in the ordinary course), the Conversion Price shall
be adjusted immediately after the record date for such stock dividend. The Conversion Price shall be adjusted by multiplying the
current Conversion Price in effect on such record date by a fraction of which the numerator shall be the total number of Common
Shares outstanding on the record date and of which the denominator shall be the total number of Common Shares outstanding on the record
date plus the number of additional Common Shares which shall result from such issuance (assuming for this purpose that all additional
Common Shares issuable upon the exercise of the conversion rights of the securities convertible into additional Common Shares had
been issued).










    	 	9	 



     


    
		(3)	In case the Corporation shall fix a record date for the issuance of rights, options or warrants
to all or substantially all the holders of its outstanding Common Shares entitling them to subscribe for or purchase additional
Common Shares or shares of any other class of the Corporation or securities convertible into Common Shares or shares of any other
class of the Corporation, and if such issuance has or is likely to have a material adverse effect on the conversion privilege or
right of the Debentureholder hereunder, then the Conversion Price shall be adjusted appropriately as determined by the Directors,
acting reasonably. If all such rights, options or warrants are not so issued or if all such rights, options or warrants are not
exercised prior to the expiration thereof, the Conversion Price shall be readjusted to the Conversion Price which would then be
in effect if such record date had not been fixed, and the Conversion Price shall be further adjusted as aforesaid based upon the
number of additional Common Shares (or securities convertible into additional Common Shares) actually issued upon the exercise
of such rights, options or warrants, as the case may be.



		(4)	No adjustments of the Conversion Price shall be made pursuant to Sections 3.4(2) or 3.4(3) if the
Holder is permitted (with the prior written consent of the TSXV) to participate in such issuance by way of stock dividend or in
the issue of such options, rights or warrants or such distribution, as the case may be, as though and to the same effect as if
it had converted its Convertible Debenture into Common Shares prior to the applicable record date or effective date for such issuance
by way of stock dividend or the issue of such options, rights or warrants or such distribution, as the case may be.



		(5)	In any case in which this Article shall require that an adjustment to the Conversion Price shall
become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (i)
issuing to the Holder converted after such record date and before the occurrence of such event the additional Common Shares issuable
upon such conversion by reason of the adjustment required by such event and (ii) paying to the Holder cash in lieu of any fractional
interest to which he is entitled pursuant to Section 3.3. Notwithstanding the foregoing, the Corporation shall deliver to the Holder
an appropriate instrument evidencing the Holder's rights to receive such additional Common Shares and such cash upon the occurrence
of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour
of holders of record of Common Shares on or after the Date of Conversion.










    	 	10	 



     


    
		(6)	The adjustments provided for in this Section 3.4 are cumulative and shall be computed to the nearest
one-tenth of one cent and will be made successively whenever an event referred to therein occurs. Notwithstanding the foregoing,
no adjustment of the Conversion Price shall be made in any case in which the resulting increase or decrease in the Conversion Price
would be less than one percent of the then prevailing Conversion Price. Any adjustment that would otherwise have been required
to be made, but for the minimum percentage threshold, shall be carried forward and made at the time of and together with the next
subsequent adjustment to the Conversion Price which, together with any and all such adjustments so carried forward, shall result
in an increase or decrease in the Conversion Price by not less than one percent.



3.5             
Certificate as to Adjustment


The Corporation
shall from time to time immediately after the occurrence of any event which requires an adjustment in the Conversion Price, prepare
an Officers' Certificate specifying the nature of the event requiring the adjustment, the amount of the adjustment necessitated
and the method of calculation and the facts relied upon in making such calculation. The Corporation shall forthwith give notice,
in the manner specified in Section 8.1, of such adjustment to the Holder, which notice shall specify the Conversion Price after
such adjustment and the event requiring such adjustment.


3.6             
Reclassifications, Reorganizations, etc.


In case of any amalgamation
of the Corporation with, or merger of the Corporation into, any other corporation with the result that the Corporation ceases to
exist in its present capacity, or in case of any sale, transfer or other disposition of all or substantially all of the assets
of the Corporation, the successor Corporation or holder of the Corporation's assets as the case may be shall give notice in the
manner specified in Section 8.1 to the Debentureholder. Such notice shall confirm that the Holder shall have the right to convert
the Debenture into the kind and amount of shares and other securities and property receivable upon such amalgamation, merger or
sale by a holder of the number of Common Shares into which such Debenture might have been converted immediately prior to such event.
Such notice shall confirm adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for
in this Article. The above provisions of this Section shall similarly apply to successive amalgamations, mergers, sales, transfers
or other dispositions.


3.7             
Notice to Debentureholder of Certain Events


In the event that



    	 	11	 



     


    
		(1)	any of the events referred to in subparagraphs 3.4(1), 3.4(2), 3.4(3), or 3.6 shall occur; or






		(2)	there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Corporation;



the Corporation shall
give notice, in the manner specified in Section 8.1, to the Debentureholder, of the action proposed to be taken and the date on
which the books of the Corporation shall close or a record shall be taken for such event. The Corporation shall only be required
to specify in such notice such particulars of such action as shall have been fixed and determined at the date on which such notice
is given. Such notice shall also specify the date as of which the holder of Debentures and Common Shares of record shall participate
in such event, or shall be entitled to exchange their Debenture or Common Shares for securities or other property deliverable upon
such event. Such written notice shall be given not less than seven (7) Business Days prior to the record date or the date on which
the Corporation's transfer books are to be closed with respect thereto.


3.8             
Legend on Share Certificate Issued upon Conversion


The Holder
acknowledges that, if the Holder provides a Conversion Notice prior to August 27, 2017, the certificate(s) representing the
Common Shares issued upon the conversion shall bear a legend as follows:


“UNLESS
PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE AUGUST 27, 2017.”


In addition, the
Holder acknowledges that the certificate(s) representing the Common Shares issued upon conversion shall bear the following legend:


"THE SECURITIES REPRESENTED
HEREBY, OR THAT MAY BE ACQUIRED UPON CONVERSION HEREOF, (THE “SECURITIES”) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES

LAWS OR THE COMPANY SHALL HAVE RECEIVED AN OPINION OF COUNSEL FOR THE HOLDER, REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL,
THAT REGISTRATION OF SUCH SECURITIES UNDER THE ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED."







3.9             
Cancellation of Debenture


A Debenture surrendered
for conversion in full shall be cancelled by the Corporation and no Debenture shall be issued in substitution therefor.

and timely filed, all material tax returns relating to taxes required to be filed by it with the appropriate governmental authority.
The Corporation has duly and timely paid all taxes that are due and payable by it, except for taxes that are not material in amount
or that are being contested diligently and in good faith through appropriate proceedings. The Corporation has made adequate provision
in its financial statements or its books and records, as applicable, for the payment of all material taxes that it owes. There
is no material inquiry, action, suit, dispute, objection, appeal, investigation, audit, claim, or other proceeding either in progress,
pending, or to the knowledge of the Corporation threatened by any governmental authority regarding any taxes or tax returns. The
Corporation has not requested, offered to enter into, entered into any agreement or arrangement, or executed any waiver providing
for any extension of time within which the Corporation is required to pay, remit, or collect any taxes, file any tax returns, or
under which any governmental authority may assess, reassess, or collect taxes for which the Corporation is or may be liable.



		(8)	The Corporation is not subject to any judgment, order, writ, injunction, decree, or award, or to
any restriction, rule, or regulation (other than customary or ordinary course restrictions, rules, and regulations consistent or
similar with those imposed on other Persons engaged in similar businesses) that has not been stayed or for which enforcement has
not been suspended, which has a Material Adverse Effect on the Corporation, its Property, or its business.



		(9)	There are no actions, suits, or proceedings pending or, to the knowledge of the Corporation, threatened
against or affecting the Corporation or the Property of the Corporation.

after the date of such financial statements.



		(11)	The Corporation has good and marketable title to all of its material Property, in each case subject
to no Liens (other than in favour of the Holder).




    	 	14	 



     


    
		(12)	The Corporation has not violated or failed to comply with any applicable law applicable to its
business, except where such violations or failures to comply could not reasonably be expected
to have a Material Adverse Effect. The Corporation has not received any notice to the effect that, or has otherwise been advised
that, it is not in compliance with any applicable law and the Corporation does not know of any currently existing circumstances
that are likely to result in the violation of any applicable law, the non-compliance or violation of which could reasonably be
expected to have a Material Adverse Effect.









		(13)	No Event of Default has occurred and no event has occurred that (with the giving of notice, the
lapse of time, or both) would constitute an Event of Default. The Corporation is not in default under any agreement, guarantee,
indenture, or instrument to which it is a party or by which it is bound, the breach of which could reasonably be expected to cause
a Material Adverse Effect or affect its ability to perform any of its obligations under any Credit Document to which it is a party.



		(14)	All information provided by or on behalf of the Corporation to the Holder for purposes of, or in
connection with, any Credit Document or any other transaction contemplated by this Debenture (including any information provided
in the future) is or will be true and accurate in all material respects as of the date on which that information is dated or certified
and not incomplete by omitting to state any material fact necessary to make that information not misleading at that time in light
of the then-current circumstances. There is no fact now known to the Corporation that has had, or could reasonably be expected
to have, a Material Adverse Effect.
