3.6 Written Agreement. Every Option shall be evidenced by a written agreement between the Company and the Optionee. If there is any
inconsistency between the terms of the agreement and this Plan the terms of this Plan shall govern. 
  

	4.	 CONDITIONS GOVERNING THE GRANTING & EXERCISING OF OPTIONS 



4.1 Agreements must specify Exercise Period and Price, Vesting and Number of Shares. In granting an Option, the Board must specify a particular
time period or periods during which the Option may be exercised, the exercise price required to purchase the Shares subject to the Option and any vesting terms and conditions of the Option, including the number of Shares in respect of which the
Option may be exercised during each such time period. 
 4.2 Minimum Exercise Price of Options. The exercise price of an Option shall not be
less than the Market Price, less, if the Shares are listed on the TSX-V, the maximum discount permitted by the Exchange, at the time of granting the Option. If the Shares are listed on the TSX-V, no Options shall be granted which are exercisable at a price of less than $0.05 per Share. 
 4.3 Number of
Shares subject to Option. The number of Shares reserved for issuance to an Optionee pursuant to an Option, together with all other stock options granted to the Optionee in the previous 12 months, shall not exceed, at the time of granting of
the Option: 
  

	 	(a)	 5% of the outstanding Shares, unless the Company has obtained disinterested shareholder approval or the Shares
are listed on the TSX; 















	 	(b)	 2% of the outstanding Shares, if the Optionee is a Consultant and the Shares are listed on the TSX-V; or 


  

	 	(c)	 2% of the outstanding Shares (including all other Shares reserved for issuance to all Optionees providing
investor relations services to the Company), if the Optionee is engaged in providing investor relations services to the Company and the Shares are listed on the TSX-V. 



4.4 Vesting of Options. Subject to further vesting requirements required by the Board on granting of an Option, all Options shall vest and be
exercisable on the following terms: 
  

	 	(a)	 If Optionee is Providing Investor Relations Services: If the Optionee is a Consultant providing investor
relations services to the Company and the Shares are listed on the TSX-V, any Option granted to the Consultant must vest in stages over at least 12 months with no more than one quarter of the Option vesting in
any three month period. 


  

	 	(b)	 If there is a Change of Control: If a Change of Control is agreed to by the Company or events which
might lead to a Change of Control are commenced by third parties, all Options, subject to the Exchange’s approval (if required), shall vest immediately and be fully exercisable notwithstanding the terms thereof. For the purposes hereof
“Change of Control” shall mean: 


  

	 	(i)	 any transaction or series of related transactions as a result of which any person, entity or group acquires
ownership, after the date of an Option, of at least 20% of the Shares and they or their representatives become a majority of the Board or assume control or direction over the management or day-to-day operations of the Company; or 


  

	 	(ii)	 an amalgamation, merger, arrangement, business combination, consolidation or other reorganization of the
Company with another entity or the sale or disposition of all or substantially all of the assets of the Company, as a result of either of which the Company ceases to exist, be publicly traded or the management of the Company or Board do not comprise
a majority of the management or a majority of the board of directors, respectively, of the resulting entity, 


 and to
permit Optionees to participate in any of the foregoing, the Board may make appropriate provision for the exercise of Options conditional upon the Shares so issued being taken-up and paid for pursuant to any
of the foregoing. 
 Subject to the approval of the Exchange if the Optionee is a Consultant providing investor relations services for the Company, the
Board may advance, at any time, the dates upon which any or all Options shall vest and become exercisable, regardless of the terms of vesting set out in this Plan or the agreement. 

4.5 [Intentionally left blank]  
 4.6 Expiry of
Options. Each Option shall expire not later than 10 years from the day on which the Option is granted. 












 4.7 Expiry of Options during or immediately after Trading Blackout Periods. If an Option
expires during, or within five trading days after, a Blackout Period then, notwithstanding Section 4.6 or the terms of the Option, the term of the Option shall be extended and the Option shall expire 10 trading days after the termination of the
Blackout Period. 
 4.8 Death or Disability of Optionee. If an Optionee dies or suffers a Disability prior to the expiry of an Option, the
Optionee’s legal representatives, before the earlier of the expiry date of the Option and the first anniversary of the Optionee’s death or Disability, may exercise that portion of an Option which has vested as at the date of death or
Disability. For the purposes hereof “Disability” shall mean any inability of the Optionee arising due to medical reasons which the Board considers likely to permanently prevent or substantially impair Optionee being an Employee,
Management Company Employee, Consultant, Officer or Director. 
 4.9 Cessation as an Optionee (With Cause). If an Optionee ceases to be a
Director, Officer, Consultant, Employee or Management Company Employee by reason of termination or removal for cause any Option shall terminate immediately on such termination or removal and not be exercisable by the Optionee unless otherwise
determined by the Board. 
 4.10 Cessation as an Optionee (Without Cause). If an Optionee ceases to be any of a Director, Officer, Consultant,
Employee or Management Company Employee for any reason except as provided in sections 4.8 or 4.9, any Option shall be exercisable to the extent that it has vested and was exercisable as at the date of such cessation, unless further vesting is
permitted by the Board, and must terminate on the earlier of the expiry date of the Option and the 90th day after the Optionee ceased to be any of a Director, Officer, Consultant, Employee or Management Company Employee, or such other date as may be
reasonably determined by the Board. 
 4.11 No Assignment of Options. No Option or any right thereunder or in respect thereof shall be
transferable or assignable otherwise than by will or pursuant to the laws of succession except that, if permitted by the rules and policies of the Exchange, an Optionee shall have the right to assign any Option to a corporation wholly-owned by them.

 4.12 Restriction on Resale of Shares Issued on Exercise of an Option. If the Optionee is an Insider or the Option is exercisable for a
price less than the Market Price at the time the Option is granted, the Shares issued upon the exercise of the Option shall be subject to a four month hold period from the time the Option was granted and the certificates representing such Shares
shall be legended accordingly. 
 4.13 Notice of Exercise of an Option. Options shall be exercised only in accordance with the terms and
conditions of the agreements under which they are respectively granted and shall be exercisable only by notice in writing to the Company. 
 4.14
Payment on Exercise of an Option. Options may be exercised in whole or in part at any time prior to their lapse or termination. Shares purchased by an Optionee on exercise of an Option shall be fully paid for in cash or by certified
cheque, bank draft or money order at the time of their purchase. 
 4.15 Condition to Issuance of Shares. The Board may require, as a
condition of the issuance of Shares or delivery of certificates representing such Shares upon the exercise of any Option and to ensure compliance with any applicable laws, regulations, rules, orders and requirements that the Optionee or the
Optionee’s heirs, executors or other legal representatives, as applicable, make such covenants, agreements and representations as the Board deems necessary or desirable. 












 4.16 Withholding or Deductions of Taxes. The Company may deduct, withhold or require an
Optionee, as a condition of exercise of an Option, to withhold, pay, remit or reimburse any taxes or similar charges, which are required to be paid, remitted or withheld in connection with the exercise of any Option. 

4.17 Cashless Exercise of Options. If the Shares are listed on the TSX, an Optionee may elect by notice in writing to the Company to surrender
to the Company all or part of an Option, to the extent that the Option has vested and remains unexercised, in consideration of an amount equal to the difference between the aggregate fair market value (based on the weighted average trading price of
the Shares on the TSX during the 10 trading days preceding the date of surrender) of the Shares which could have otherwise been purchased upon the exercise of the Option and the aggregate exercise price which the Optionee would have paid upon such
exercise. The Company, in its sole discretion, may: 
  

	 	(a)	 satisfy such amount due to the Optionee by payment in cash or issuance of Shares using such fair market value
of the Shares as the issuance price; or 


  

	 	(b)	 refuse to accept such surrender, whereupon the Option shall remain in full force and effect.



  

	5.	 RESERVATION OF SHARES FOR OPTIONS 



5.1 Sufficient Authorized Shares to be Reserved. Whenever the constating documents of the Company limit the number of authorized Shares, a
sufficient number of Shares shall be reserved by the Board to satisfy the exercise of Options. Shares that were the subject of Options that have lapsed or terminated shall thereupon no longer be in reserve and may once again be subject to an Option.

 5.2 Maximum Number of Shares to be Reserved Under Plan. The aggregate number of Shares which may be subject to issuance pursuant to Options
and any stock options granted under any other previous or current stock option plan or security compensation arrangement shall be 10% of the outstanding Shares at the time of granting the Options. If any Option expires or otherwise terminates for
any reason without having been exercised in full, the number of Shares in respect of such expired or terminated Option shall again be available for the purposes of granting Options pursuant to this Plan. 

5.3 Maximum Number of Shares Reserved for Insiders. All Options, together with all of the Company’s other previously granted stock options,
stock option plans, employee stock purchase plans or any other compensation or incentive mechanisms involving the issuance or potential issuance of Shares, shall not result, at the time of granting, in: 

 

	 	(a)	 the number of Shares reserved for issuance pursuant to Options granted to Insiders exceeding 10% of the Shares
outstanding; 


  

	 	(b)	 the issuance to Insiders, within a one year period, of Shares totalling in excess of 10% of the Shares
outstanding; or 















	 	(c)	 the issuance to any one individual, within a one year period, of Shares totalling in excess of 5% of the Shares
outstanding, 


 unless the disinterested shareholders have approved thereof. 

 

	6.	 CAPITAL REORGANIZATIONS 



6.1 Share Consolidation or Subdivision. If the Shares are at any time subdivided or consolidated, the number of Shares reserved for Options shall
be similarly increased or decreased and the price payable for any Shares that are then subject to issuance shall be decreased or increased proportionately, as the case may require, so that upon exercising each Option the same proportionate
shareholdings at the same aggregate purchase price shall be acquired after such subdivision or consolidation as would have been acquired before. 
 6.2
Stock Dividend. If the Shares are at any time changed as a result of the declaration of a stock dividend thereon, the number of Shares reserved for Options shall be increased proportionately and the price payable for any Shares that
are then subject to issuance shall be decreased proportionately so that upon exercising each Option the same proportionate shareholdings at the same aggregate purchase price shall be acquired after such stock dividend as would have been acquired
before. 
 6.3 No Fractional Shares. No adjustment made pursuant to this Part shall require the Company to issue a fraction of a Share and any
fractions of a Share shall be rounded up or down to the nearest whole number, with one-half a Share being rounded up to one Share. 

6.4 No Adjustment for Cash Dividends or Rights Offerings. No adjustment shall be made to any Option pursuant to this Part in respect of the
payment of any cash dividend or the distribution to the shareholders of the Company of any rights to acquire Shares or other securities of the Company.

Option or any agreement entered into pursuant to this Plan contravenes any applicable law, rule, regulation or order, or any policy, bylaw or regulation of the Exchange or any regulatory body having authority over the Company or this Plan, such
provision shall be deemed to be amended to the extent required to bring such provision into compliance therewith, but the Company shall not be responsible to pay and shall not incur any penalty, liability or further obligation in connection
therewith.

Optionee and in no event shall it be obliged to take any action, including the filing of any prospectus, registration statement or similar document, in order to permit the issuance and delivery of any Shares upon the exercise of any Option in order
