Subject to subsections 4.3 and 4.4, an Option shall
be granted as fully Vested on the Grant Date, and may be exercised to purchase any number of Shares up to the number of Unissued Option
Shares at any time after the Grant Date, provided that this Plan has been previously approved by the shareholders of the Company, where
such prior approval is required by Exchange policies, up to 4:00 p.m. local time on the Expiry Date and shall not be exercisable
thereafter.


 


	4.2	Manner of Exercise


 


The Option shall be exercisable by delivering to
the Company a notice specifying the number of Shares in respect of which the Option is exercised together with payment in full of the
Option Price for each such Share. Upon notice and payment there will be binding contract for the issue of the Shares in respect of which

An Option shall be granted hereunder as fully Vested,
unless a vesting schedule is imposed by the Board as a condition of the grant on the Grant Date; and provided that if the Option is being

    -5-


    

 


	4.4	Termination of Employment


 


If an Optionee ceases to be an Eligible Person,
his or her Option shall be exercisable as follows:


 


	 	(a)	Death or Disability


 


If the Optionee ceases to be an Eligible Person, due to his
or her death or Disability or, in the case of an Optionee that is a company, the death or Disability of the person who provides management
or consulting services to the Company or to any entity controlled by the Company, the Option then held by the Optionee shall be exercisable
to acquire Vested Unissued Option Shares at any time up to but not after the earlier of:


 


	 	(i)	365 days after the date of death or Disability; and


 


	 	(ii)	the Expiry Date.


 


	 	(b)	Termination For Cause


 


If the Optionee, or in the case of a Management Company Employee
or a Consultant Company, the Optionee’s employer, ceases to be an Eligible Person as a result of termination for cause, as that
term is interpreted by the courts of the jurisdiction in which the Optionee, or, in the case of a Management Company Employee or a Consultant
Company, of the Optionee’s employer, is employed or engaged; any outstanding Option held by such Optionee on the date of such termination
shall be cancelled as of that date.


 


	 	(c)	Early Retirement, Voluntary Resignation or Termination Other than For Cause


 


If the Optionee or, in the case of a Management Company Employee
or a Consultant Company, the Optionee’s employer, ceases to be an Eligible Person due to his or her retirement at the request of
his or her employer earlier than the normal retirement date under the Company’s retirement policy then in force, or due to his or
her termination by the Company other than for cause, or due to his or her voluntary resignation, the Option then held by the Optionee
shall be exercisable to acquire Vested Unissued Option Shares at any time up to but not after the earlier of the Expiry Date and the date
which is 90 days after the Optionee or, in the case of a Management Company Employee or a Consultant Company, the Optionee’s employer,
ceases to be an Eligible Person.


 


	4.5	Effect of a Take-Over Bid


 


If a bona fide offer (an “Offer”)
for Shares is made to the Optionee or to shareholders of the Company generally or to a class of shareholders which includes the Optionee,
which Offer, if accepted in whole or in part, would result in the offeror becoming a control person of the Company, within the meaning
of subsection 1(1) of the Securities Act, the Company shall, immediately upon receipt of notice of the Offer, notify
each Optionee of full particulars of the Offer, whereupon the Option Shares subject to such Option may be exercised in whole or in part
by the Optionee so as to permit the Optionee to tender the Option Shares received upon such exercise, pursuant to the Offer. However,
if:


 


	 	(a)	the Offer is not completed within the time specified therein; or


 






     


    -6-


    

 


	 	(b)	all of the Option Shares tendered by the Optionee pursuant to the Offer are not taken up or paid for by the offeror in respect thereof, then the Option Shares received upon such exercise, or in the case of clause (b) above, the Option Shares that are not taken up and paid for, may be returned by the Optionee to the Company and reinstated as authorized but unissued Shares and with respect to such returned Option Shares, the Option shall be reinstated as if it had not been exercised. If any Option Shares are returned to the Company under this subsection 4.5, the Company shall immediately refund the exercise price to the Optionee for such Option Shares.


 


	4.6	Acceleration of Expiry Date


 


If at any time when an Option granted under the
Plan remains unexercised with respect to any Unissued Option Shares, an Offer is made by an offeror, the Directors may, upon notifying
each Optionee of full particulars of the Offer, declare all Option Shares issuable upon the exercise of Options granted under the Plan,
are Vested (subject to the proviso below), and declare that the Expiry Date for the exercise of all unexercised Options granted under
the Plan is accelerated so that all Options will either be exercised or will expire prior to the date upon which Shares must be tendered
pursuant to the Offer, provided that where an Option was granted to a consultant providing Investor Relations Activities, the Directors
declaration that Option Shares issuable upon the exercise of such Options granted under the Plan be Vested with respect to such Option
Shares, is subject to prior approval of the Exchange. The Directors shall give each Optionee as much notice as possible of the acceleration
of the Options under this section, except that not less than five (5) business days and not more than 35 days notice is required.


 


	4.7	Effect of a Change of Control


 


If a Change of Control occurs, all Option Shares
subject to each outstanding Option may be exercised in whole or in part by the Optionee.


 


	4.8	Exclusion From Severance Allowance, Retirement Allowance or Termination Settlement


 


If the Optionee, or, in the case of a Management
Company Employee or a Consultant Company, the Optionee’s employer, retires, resigns or is terminated from employment or engagement
with the Company or any subsidiary of the Company, the loss or limitation, if any, by the cancellation of the right to purchase Option
Shares under the Option Agreement shall not give rise to any right to damages and shall not be included in the calculation of nor form
any part of any severance allowance, retiring allowance or termination settlement of any kind whatsoever in respect of such Optionee.


 


	4.9	Shares Not Acquired or Exercised


 


Any Unissued Option Shares not acquired by an Optionee
under an Option which has expired, and any Option Shares acquired by an Optionee under an Option when exercised, may be made the subject
of a further Option granted pursuant to the provisions of the Plan.


 


	4.10	Extension of Term During Trading Black Out


 


In the event the Expiry Date of an Option falls
on a date during a trading black out period that has been self imposed by the Company, the Expiry Date of the Option will be extended
to the 10th business day following the date that the self imposed trading black out period is lifted by the Company. For
greater certainty, the Expiry Date of an Option will not be extended in the event a cease trade order is issued by a securities regulatory
authority against the Company or an Optionee.

		5.	ADJUSTMENT OF OPTION PRICE AND NUMBER OF OPTION SHARES



 


	5.1	Share Reorganization


 


Whenever the Company issues Shares to all or substantially
all holders of Shares by way of a stock dividend or other distribution, or subdivides all outstanding Shares into a greater number of
Shares, or combines or consolidates all outstanding Shares into a lesser number of Shares (each of such events being herein called a “Share
Reorganization”) then effective immediately after the record date for such dividend or other distribution or the effective date
of such subdivision, combination or consolidation, for each Option:


 


	 	(a)	the Option Price will be adjusted to a price per Share which is the product of:


 


	 	(i)	the Option Price in effect immediately before that effective date or record date; and


 


	 	(ii)	a fraction, the numerator of which is the total number of Shares outstanding on that effective date or record date before giving effect to the Share Reorganization, and the denominator of which is the total number of Shares that are or would be outstanding immediately after such effective date or record date after giving effect to the Share Reorganization; and


 


	 	(b)	the number of Unissued Option Shares will be adjusted by multiplying (i) the number of Unissued Option Shares immediately before such effective date or record date by (ii) a fraction which is the reciprocal of the fraction described in subparagraph (a)(ii).


 


	5.2	Special Distribution


 


Subject to the prior approval of the Exchange,
whenever the Company issues by way of a dividend or otherwise distributes to all or substantially all holders of Shares:


 


	 	(a)	shares of the Company, other than the Shares;


 


	 	(b)	evidences of indebtedness;


 


	 	(c)	any cash or other assets, excluding cash dividends (other than cash dividends which the Board of Directors of the Company has determined to be outside the normal course); or


 


	 	(d)	rights, options or warrants, then to the extent that such dividend or distribution does not constitute a Share Reorganization (any of such non-excluded events being herein called a “Special Distribution”), and effective immediately after the record date at which holders of Shares are determined for purposes of the Special Distribution, for each Option the Option Price will be reduced, and the number of Unissued Option Shares will be correspondingly increased, by such amount, if any, as is determined by the Board in its sole and unfettered discretion to be appropriate in order to properly reflect any diminution in value of the Option Shares as a result of such Special Distribution.


 






     


    -8-


    

 


	5.3	Corporate Organization


 


Whenever there is:


 


	 	(a)	a reclassification of outstanding Shares, a change of Shares into other shares or securities, or any other capital reorganization of the Company, other than as described in subsections 5.1 or 5.2;


 


	 	(b)	a consolidation, merger or amalgamation of the Company with or into another corporation resulting in a reclassification of outstanding Shares into other shares or securities or a change of Shares into other shares or securities; or


 


	 	(c)	a transaction whereby all or substantially all of the Company’s undertaking and assets become the property of another corporation,


 


(any such event being herein called a “Corporate Reorganization”)
the Optionee will have an option to purchase (at the times, for the consideration, and subject to the terms and conditions set out in
the Plan) and will accept on the exercise of such option, in lieu of the Unissued Option Shares which he would otherwise have been entitled
to purchase, the kind and amount of shares or other securities or property that he would have been entitled to receive as a result of
the Corporate Reorganization if, on the effective date thereof, he had been the holder of all Unissued Option Shares or if appropriate,
as otherwise determined by the Directors.


 


	5.4	Determination of Option Price and Number of Unissued Option Shares


 


If any questions arise at any time with respect
to the Option Price or number of Unissued Option Shares deliverable upon exercise of an Option following a Share Reorganization, Special
Distribution or Corporate Reorganization, such questions shall be conclusively determined by the Company’s auditor, or, if they
decline to so act, any other firm of Chartered Accountants in Vancouver, British Columbia, that the Directors may designate and who will
have access to all appropriate records and such determination will be binding upon the Company and all Optionees.


 


	5.5	Regulatory Approval


 


Any adjustment to the Option Price or the number
of Unissued Option Shares purchasable under the Plan pursuant to the operation of any one of subsection 5.1, 5.2 or 5.3 is subject to
the approval of the Exchange where required pursuant to their policies, and compliance with the applicable securities rules or regulations
of any other governmental authority having jurisdiction.

	6.2	Necessary Approvals

way of an ordinary resolution of the disinterested shareholders in the case of a new Plan, and the written acceptance of the Plan by the

shall only be exercised upon the receipt of such approval, where it is required by the policies of the Exchange. The obligation of the
Company to sell and deliver Shares in accordance with the Plan is subject to compliance with the policies of the Exchange and applicable
securities rules or regulations of any governmental authority having jurisdiction. If any Shares cannot be issued to any Optionee
for any reason, including, without limitation, the failure to comply with such policies, rules or regulations, then the obligation
of the Company to issue such Shares shall terminate and any Option Price paid by an Optionee to the Company shall be immediately refunded
to the Optionee by the Company.

and final authority in their discretion, but subject to the express provisions of the Plan, to interpret the Plan, to prescribe, amend
and rescind rules and regulations relating to the Plan and to make all other determinations deemed necessary or advisable in respect
of the Plan. Except as set forth in subsection 5.4, the interpretation and construction of any provision of the Plan by the Directors
shall be final and conclusive. Administration of the Plan shall be the responsibility of the appropriate officers of the Company and all
costs in respect thereof shall be paid by the Company.


 


	6.4	Income Taxes


 


As a condition of and prior to participation of
the Plan any Optionee shall on request authorize the Company in writing to withhold from any remuneration otherwise payable to him or
her any amounts required by any taxing authority to be withheld for taxes of any kind as a consequence of his or her participation in
the Plan.

applicable law and to the prior approval, if required, of the Exchange or any other regulatory body having authority over the Company
or the Plan, suspend, terminate or discontinue the Plan at any time, or amend or revise the terms of the Plan or of any Option granted
under the Plan and the Option Agreement relating thereto, provided that no such amendment, revision, suspension, termination or discontinuance
shall in any manner adversely affect any option previously granted to an Optionee under the Plan without the consent of that Optionee.
Any amendments to the Plan or options granted to Insiders thereunder will be subject to the approval of the shareholders, where such approval
is required by the policies of the Exchange.


 


	6.6	Form of Notice

The Company makes no representation or warranty
as to the future market value of any Shares issued in accordance with the provisions of the Plan.


 


	6.8	Compliance with Applicable Law


 


If any provision of the Plan or any Option Agreement
contravenes any law or any order, policy, by-law or regulation of any regulatory body or Exchange having authority over the Company or
the Plan, then such provision shall be deemed to be amended to the extent required to bring such provision into compliance therewith.


 


	6.9	No Assignment


 


No Optionee may assign any of his or her rights
under the Plan or any Option granted thereunder.


 


	6.10	Rights of Optionees


 


An Optionee shall have no rights whatsoever as
a shareholder of the Company in respect of any of the Unissued Option Shares (including, without limitation, voting rights or any right
to receive dividends, warrants or rights under any rights offering).


 


	6.11	Conflict


 


In the event of any conflict between the provisions
of this Plan and an Option Agreement, the provisions of this Plan shall govern.


 


	6.12	Governing Law


 


The Plan and each Option Agreement issued pursuant
to the Plan shall be governed by the laws of the Province of British Columbia.


 


	6.13	Time of Essence


 


Time is of the essence of this Plan and of each
Option Agreement. No extension of time will be deemed to be or to operate as a waiver of the essentiality of time.


 


	6.14	Entire Agreement

entire agreement between the Company and the Optionees relative to the subject matter hereof and supersedes all prior agreements, undertakings
and understandings, whether oral or written.
