its Affiliates (as defined below), upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business, to acquire a proprietary interest in the
Company. It is anticipated that providing such persons with a direct stake in the Company's welfare will assure a closer identification of their interests with those of the Company, thereby

SECTION 2.  ADMINISTRATION OF PLAN; COMMITTEE POWERS

        (a)   Administration of Plan.    The Plan shall be administered by the Board or, at the discretion of the Board, by a
committee of the Board consisting of not less than two (2) directors (the "Committee");  provided, however, that if any member of the Committee is not a "Non-Employee Director"
within the meaning of Rule 16b-3(b)(3) of the Exchange Act, then any Awards granted to individuals subject to the reporting requirements of Section 16 of the Exchange Act
shall be approved by the Board. Notwithstanding the foregoing, after the end of the reliance period as defined in Treasury Regulation Section 1.162-27(f), to the extent applicable,
Awards granted to "Covered Employees" which might reasonably be anticipated to result in the payment of employee remuneration that would otherwise exceed the limit on employee remuneration deductible
for income tax purposes pursuant to Section 162(m) of the Code shall be approved by a Committee composed solely of two or more "Outside Directors" (each within the meaning of
Section 162(m) of the Code). All references herein to the Committee shall be deemed to refer to the entity then responsible for administration of the Plan at the relevant time
(i.e., either the Board or a committee of the Board, as applicable). 

        (b)   Powers of Committee.    The Committee shall have the power and authority to grant Awards consistent with the
terms of the Plan, including the power and authority: 

        (i)    to
select the employees, directors and Consultants of the Company and its Affiliates to whom Awards may from time to time be granted; 

        (ii)   to
determine the time or times of grant, and the type of Award to be granted which shall include Incentive Stock Options, Non-Qualified Stock Options,
Restricted Stock Awards, and Unrestricted Stock Awards, or any combination of the forgoing, granted to any one or more Grantees; 

        (iii)  to
determine the number of shares of Common Stock to be covered by any Award; 

        (iv)  to
determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and
conditions may differ among individual Awards and Grantees, and to approve the form of written instruments evidencing the Awards; 

3

 

        (v)   to
accelerate at any time the exercisability or vesting of all or any portion of any Award and/or to include provisions in Awards providing for such acceleration; 

        (vi)  to
impose any limitations on Awards granted under the Plan, including limitations on transfers, repurchase provisions and the like and to exercise repurchase rights
or obligations; 

        (vii) subject
to the provisions of Section 5(a)(ii), to extend at any time the period in which Stock Options may be exercised; and 

        (viii) at
any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem
advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to
decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan. 

        All
decisions and interpretations of the Committee shall be binding on all persons, including the Company, its Affiliates, the Company's stockholders and Grantees. 

SECTION 3.  STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

        (a)   Stock Issuable.    The maximum aggregate number of shares of Common Stock reserved and available for issuance
under the Plan shall be 5,000,000 shares of Common Stock. All such shares of Common Stock available for issuance under the Plan shall be available for issuance for any and all types of Awards
hereunder, and in any and all combinations thereof, including as Incentive Stock Options. The foregoing share numbers are subject to adjustment as provided in Section 3(b). For purposes
of this Section 3(a), the shares of Common Stock underlying any Awards which are forfeited (including, but not limited to, pursuant to a cashless exercise under Section 5(a)(iv)(C)
hereof), canceled, reacquired by the Company, satisfied without the issuance of Common Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Common Stock
available for issuance under the Plan. The maximum number of shares of Common Stock that may be awarded to any one grantee during any calendar year shall not exceed 500,000. 

        The
number of shares of Common Stock issuable to Insiders, at any time, under all security-based compensation arrangements of the Company and its Affiliates, cannot exceed ten percent
(10%) of the then issued and outstanding shares of Common Stock. In addition, the number of shares of Common Stock issued to Insiders, within any one year period, under all security-based compensation
arrangements of the Company and its Affiliates, cannot exceed ten percent (10%) of the then issued and outstanding shares of Common Stock. 

        (b)   Changes in Stock.    Subject to Section 3(c) hereof, if, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company's capital stock, the outstanding shares of Common Stock are increased or
decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other
non-cash assets are distributed with respect to such shares of Common Stock or other securities, or, if, as a result of any merger, consolidation or sale of all or substantially all of the
assets of the Company, the outstanding shares of Common Stock are converted into or exchanged for a different number or kind of the Company or any successor entity (or a parent or subsidiary
thereof), the Committee shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number and kind of shares
or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price per share for each outstanding Restricted Stock Award, and (iv) the exercise price
of any Stock Option. The adjustment by the Committee shall be final, binding and conclusive. No fractional shares of Common Stock shall be issued under the Plan 

4

 

resulting
from any such adjustment, but the Committee in its discretion may either make a cash payment in lieu of fractional shares or round any resulting fractional share down to the nearest
whole number. 

        To
the extent that the Committee, in its sole discretion, determines it is necessary in order to avoid distortion in the operation of the Plan, the Committee shall also adjust the number
of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration material changes in accounting practices or principles, extraordinary
dividends, and certain acquisitions or dispositions of stock or property or other similar events, provided that no such
adjustment shall be made in the case of an Incentive Stock Option, without the consent of the Grantee, if it would constitute a modification, extension or renewal of the Option within the meaning of
Section 424(h) of the Code. 

        (c)   Mergers and Other Transactions.    Upon the effectiveness of (i) a merger, reorganization or
consolidation between the Company and another person or entity (other than a holding company or an Affiliate of the Company) as a result of which the holders of the Company's outstanding voting stock
immediately prior to the transaction hold less than a majority of the outstanding voting stock of the surviving entity immediately after the transaction, or (ii) the sale of all or
substantially all of the assets of the Company to an unrelated person or entity (in each case, a "Transaction"), unless provision is made in
connection with the Transaction for the assumption of all outstanding Awards, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment
as to the number and kind of shares and, if appropriate, the per share exercise prices, as provided in Section 3(b) above, this Plan and all outstanding Awards granted hereunder, except with
respect to specific Awards as the Committee otherwise determines, shall terminate. In the event of such termination, each Grantee shall be permitted to exercise prior to the anticipated effective date
of the Transaction all outstanding Awards held by such Grantee which are then vested and exercisable; provided,  however, that the Grantee may, but will not
be required to, condition such exercise upon the effectiveness of the Transaction. 

        (d)   Dissolution or Liquidation.    In the event of a dissolution or liquidation of the Company, any outstanding
Awards issued under the Plan shall be terminated if not exercised prior to such event. 

        (e)   Substitute Awards.    The Committee may grant Awards under the Plan in substitution for stock and stock based
awards held by employees, directors or consultants of another company in connection with a merger or consolidation of such company with the Company (or any Affiliate of the Company) or the
acquisition by the Company (or any Affiliate of the Company) of property or stock of such company. 

SECTION 4.  ELIGIBILITY

        Awards
may be granted to employees, directors and Consultants (including prospective employees, directors and Consultants to whom Awards are granted in connection with written offers of
employment or other Service Relationship with the Company or any of its Affiliates) of the Company and/or its Affiliates who are responsible for, or contribute to, the management, growth or
profitability of the Company and/or its Affiliates as are selected from time to time by the Committee in its sole discretion. 

SECTION 5.  STOCK OPTIONS

        Any
Stock Option granted under the Plan shall be pursuant to an Option Agreement which shall be in such form as the Committee may from time to time approve. Option Agreements need not
be identical. 

5

 

        Stock
Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the
Company or any Affiliate, provided, however, that, an Incentive Stock Option may be granted to a
prospective employee upon the condition that such person becomes an employee and such grant shall be deemed granted effective on the date that such person commences service with the Company or an
Affiliate, with an exercise price determined as of such date in accordance with Section 5(a)(i) below. Non-Qualified Stock Options may be granted to employees, directors, and
Consultants of the Company or its Affiliates. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. 

        No
Stock Option shall be granted under the Plan after the date which is ten (10) years from the date the Plan is approved by the Board. 

        (a)   Terms of Stock Options.    Stock Options granted under the Plan shall be subject to the following terms and
conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem desirable: 

        (i)    Exercise Price.    The exercise price per share for the Common Stock covered by a Stock Option shall be
determined by the Committee at the time of grant but shall not be less than one hundred percent (100%) of the Fair Market Value on the grant date in the case of Incentive Stock Options. If an
Incentive Stock Option is granted to a 10% Owner Optionee, the exercise price per share for the Common Stock covered by such Incentive Stock Option shall be not less than one hundred ten percent
(110%) of the Fair Market Value on the grant date. Notwithstanding the foregoing, but subject to the prior approval of the Toronto Stock Exchange to the extent the Common Stock is then listed on the
Toronto Stock Exchange, an Incentive Stock Option may be granted with an exercise price lower than the minimum exercise price per share set forth above if the Incentive Stock Option is granted
pursuant to an assumption or substitution for another option in a manner qualifying under Section 424(a) of the Code. 

        (ii)   Option Term.    The term of each Stock Option shall be fixed by the Committee, but no Stock Option shall be
exercisable more than ten (10) years after the date the Stock Option is granted. If an Incentive Stock Option is granted to a 10% Owner Optionee, the term of such Stock Option shall be no more
than five (5) years from the grant date. 

        (iii)  Exercisability; Rights of a Stockholder.    Stock Options shall become exercisable at such time or times,
whether or not in installments, as shall be determined by the Committee and set forth in the Option Agreement evidencing such Option. In addition, the following provisions shall apply to each Option,
unless otherwise provided in an applicable Option Agreement: 

        (A)  No
portion of an Option may be exercised until such portion shall have vested. 

        (B)  An
Option shall be exercisable on and after the initial vesting date (as designated in the Option Agreement) and prior to the termination of the Option as
provided herein, in an amount not to exceed the aggregate number of vested Option Shares (as determined in the Option Agreement) less the number of shares previously acquired upon exercise of
such Option. Subject to Section 3(b), in no event shall an Option be exercisable for more than the total number of Option Shares underlying the Option. 

        (C)  In
the event that the Grantee's Service Relationship terminates, an Option may thereafter be exercised, to the extent it was vested and exercisable on the date of such
termination, until the date specified in Section 5(a)(iii)(D) below. Any portion of an Option that is not exercisable on the date of termination of the Service Relationship shall immediately
expire and be null and void. 

6

 

        (D)  Once
any portion of an Option becomes vested and exercisable, it shall continue to be exercisable by the Grantee or his or her representatives and legatees as
contemplated herein at any time or times prior to the earliest of (1) the date which is (a) twelve (12) months following the date on which the Grantee's Service Relationship
terminates due to death or Disability or (b) three (3) months following the date on which the Grantee's Service Relationship terminates if the termination is due to any other reason, or
(2) the expiration date set forth in the Option Agreement; provided, however, that
notwithstanding the foregoing, if the Grantee's Service Relationship is terminated for Cause, the Option shall terminate immediately and be null and void upon the date of the Grantee's termination and
shall not thereafter be exercisable. 

        (E)  A
Grantee shall have no rights of a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which
the Option has been exercised (as evidenced by an appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for
dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, expect as provided in Section 3(b). 

        (iv)  Method of Exercise.    Stock Options may be exercised in whole or in part, by giving written notice of
exercise to the Company, specifying the number of shares of Common Stock to be purchased. Payment
of the exercise price may be made by one or more of the following methods unless otherwise provided in the applicable Option Agreement: 

        (A)  in
cash, by certified or bank check, or other instrument acceptable to the Committee in U.S. funds payable to the order of the Company in an amount equal to the
exercise price of such Option Shares; 

        (B)  if
the Committee has agreed to provide financial assistance to the Grantee to enable or assist the Grantee to effect the exercise of his or her Stock Option, by the
Grantee delivering to the Company a promissory note in the principal amount of such financial assistance, together with a pledge agreement and the certificate(s) representing the shares of Common
Stock subscribed for with the proceeds of such financial assistance, such promissory note and pledge agreement to be in such form as the Committee shall approve; 

        (C)  if
permitted by the Committee, by having the Company withhold from the Option Shares a number of shares having a Fair Market Value equal to the aggregate purchase price
of the Option Shares (in which event the shares withheld shall be added back to the shares of Common Stock available for issuance under the Plan under Section 3(a)); 

        (D)  if
permitted by the Committee, by the Grantee delivering to the Company a properly executed Exercise Notice together with irrevocable instructions to a broker to
promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price, provided that in the event the
Grantee chooses such payment procedure, the Grantee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Committee shall prescribe
as a condition of such payment procedure; or 

        (E)  a
combination of the payment methods set forth in clauses (A), (B), (C) or (D) above, if applicable. 

        Payment
instruments will be received subject to collection. No certificates for Option Shares so purchased will be issued to the Grantee until the Company has completed all steps
required by law to be taken in connection with the issuance and sale of the shares, including, without limitation, obtaining from Grantee payment or provision for all withholding taxes due as a result
of the exercise of the Stock Option. The delivery of certificates representing the shares of Common Stock to be purchased pursuant 

7

 

to
the exercise of a Stock Option will be contingent upon receipt from the Grantee (or a purchaser acting in his or her stead in accordance with the provisions of the Stock Option) by the
Company of the full exercise price. 

        (b)   Annual Limit on Incentive Stock Options.    To the extent that the aggregate Fair Market Value (determined as
of the time the Option is granted) of the shares of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by a Grantee during any calendar year (under all
option plans of the Company and the "parents" and "subsidiaries" of the Company (as such terms are defined under Section 424 of the Code)) exceeds $100,000, such Incentive Stock Options
shall constitute Non-Qualified Stock Options. For purposes of this Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted. If
pursuant to the above, an Incentive Stock Option is treated as an Incentive Stock Option in part and a Non-Qualified Stock Option in part, the Grantee may designate at the time of exercise
which portion shall be deemed to be exercised, and in the absence of such express designation in writing, the portion of the Option treated as an Incentive Stock Option shall be deemed to be exercised
first. 

        (c)   Non-transferability of Options.    No Stock Option shall be transferable by the Grantee otherwise
than by will or by the laws of descent and distribution and all Stock Options shall be exercisable, during the Grantee's lifetime, only by the Grantee, or by the Grantee's legal representative or
guardian in the event of the Grantee's incapacity. Notwithstanding the foregoing, the Committee, in its sole discretion, may provide in the Option Agreement regarding a given Option that the Grantee
may transfer, without consideration for the transfer, his or her Non-Qualified Stock Options to members of his or her immediate family, to trusts for the benefit of such family members, or
to partnerships in which such family members are the only partners, or to limited liability companies in which such family members are the only members,  provided that the transferee agrees in writing
with the Company to be bound by all of the terms and conditions of this Plan and the applicable Option
Agreement. 

        (d)   Repurchase Rights.    Shares of Common Stock issued pursuant to Options may be subject to one or more
repurchase options or other conditions and restrictions as determined by the Committee and set forth in the applicable Option Agreement. The Company shall have the right to assign to any person at any
time any repurchase right it may have, whether or not such right is then exercisable. 

SECTION 6.  RESTRICTED STOCK AWARDS

        (a)   Nature of Restricted Stock Awards.    A Restricted Stock Award is an Award pursuant to which the Company may,
in its sole discretion, grant or sell at any price shares of Common Stock subject to such restrictions and conditions as the Committee may determine at the time of grant
("Restricted Stock"), and any purchase price shall be payable in cash or, if the Committee agrees to provide financial assistance to the Grantee to
enable or assist the Grantee in purchasing the Restricted Stock, by the Grantee delivering to the Company a promissory note in the principal amount of such financial assistance, together with a pledge
agreement and the certificate(s) representing the shares of Common Stock subscribed for with the proceeds of such financial assistance, such promissory note and pledge agreement to be in such form as
the Committee shall approve. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.
The grant of a Restricted Stock Award is contingent on the Grantee executing a Restricted Stock Agreement. The terms and conditions of each such Restricted Stock Agreement shall be determined by the
Committee, and such terms and conditions may differ among individual Awards and Grantees. 

        (b)   Rights as a Stockholder.    Upon execution of the Restricted Stock Agreement and payment of any applicable
purchase price, a Grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock, subject to such conditions contained in the Restricted Stock Agreement. 

8

 

Unless
the Committee shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in
Section 6(d) below, and the Grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank. 

        (c)   Restrictions.    Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or
disposed of except as specifically provided herein or in the Restricted Stock Agreement. Shares of Common Stock issued pursuant to a Restricted Stock Award may be subject to one or more repurchase
options or other conditions and restrictions as determined by the Committee and set forth in the applicable Restricted Stock Agreement. The Company shall have the right to assign to any person at any
time any repurchase right it may have, whether or not such right is then exercisable. 

        (d)   Vesting of Restricted Stock.    The Committee at the time of grant shall specify the date or dates and/or the
attainment of pre-established performance goals, objectives and other conditions on which Restricted Stock shall become vested, subject to such further rights of the Company or its assigns
as may be specified in the Restricted Stock Agreement. 

        (e)   Waiver and Reinvestment of Dividends.    The Restricted Stock Agreement may require or permit the immediate
payment, waiver or investment of dividends paid on the Restricted Stock. 

SECTION 7.  UNRESTRICTED STOCK AWARDS

        (a)   Grant or Sale of Unrestricted Stock.    The Committee may, in its sole discretion, grant or sell at any price
an Unrestricted Stock Award to any Grantee, pursuant to which such Grantee may receive shares of Common Stock free of any vesting restrictions ("Unrestricted
Stock") under the Plan. Unrestricted Stock Awards may be granted or sold as described in the preceding sentence in respect of past services or other valid consideration, or in
lieu of any cash compensation due to such individual. 

        (b)   Elections to Receive Unrestricted Stock in Lieu of Compensation.    Upon the request of a Grantee and with the
consent of the Committee, such Grantee may, pursuant to an advance written election delivered to the Company no later than the date specified by the Committee, receive a portion of the cash
compensation otherwise due to such Grantee in the form of shares of Unrestricted Stock either currently or on a deferred basis. 

        (c)   Restrictions on Transfers.    The right to receive shares of Unrestricted Stock on a deferred basis may not be
sold, assigned, transferred, pledged or otherwise encumbered, other than by will or the laws of descent and distribution. 

SECTION 8.  TAX WITHHOLDING

        (a)   Payment by Grantee.    Each Grantee shall, no later than the date as of which the value of an Award or of any
Common Stock or other amounts received thereunder first becomes includable in the gross income of the Grantee for federal income tax purposes, pay to the Company, or make arrangements satisfactory to
the Committee regarding payment of, any federal, state, foreign, or local taxes of any kind required by law to be withheld with respect to such income. The Company and its Affiliates shall, to the
extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the Grantee. 

        (b)   Payment in Stock.    Subject to approval by the Committee, a Grantee may elect to have the minimum required tax
withholding obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Common Stock to be issued pursuant to any Award a number of shares with an
aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due, or (ii) transferring to the Company shares of Common Stock owned
by the Grantee with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due. The Fair Market Value of any shares of Common
Stock 

9

 

withheld
or tendered to satisfy any such tax withholding obligation shall not exceed the amount determined by the applicable minimum statutory withholding rates. 

SECTION 9.  LEAVE OF ABSENCE

        For
purposes of the Plan, the following events shall not be deemed a termination of the Service Relationship: 

        (a)   an
approved leave of absence for military service or sickness, or for any other purpose approved by the Company;  provided, however, that if any such leave
exceeds ninety (90) days, on the ninety-first
(91st) day of such leave, the Grantee's Service Relationship shall be deemed to have terminated unless the Grantee's right to return to service is guaranteed either by a statute or by
contract; and 

        (b)   notwithstanding
the foregoing, unless otherwise designated by the Company or required by law, a leave of absence shall not be treated as service for purposes of
determining vesting under the Grantee's Option Agreement or Restricted Stock Agreement. 

SECTION 10.  AMENDMENTS AND TERMINATION

        The
Board may, at any time, amend or terminate the Plan or any outstanding Award, but no such action shall adversely affect rights under any outstanding Award without the holder's
consent unless (i) required to ensure that a Stock Option is treated as an Incentive Stock Option or (ii) to comply with applicable law. Except as herein provided, no such action of the
Board, unless taken with the approval of the stockholders of the Company, may: (a) increase the maximum number of shares of Common Stock for which Awards granted under this Plan may be issued
(except by operation of Section 3(b)); (b) amend the Plan in any other manner which the Board, in its discretion, determines would require approval of the stockholders under any
applicable law, rule or regulation to become effective even though such stockholder approval is not expressly required by this Plan; (c) alter the class of employees eligible to receive
Incentive Stock Options under the Plan; (d) extend the expiration date, or reduce the exercise price, of any Awards granted to Insiders; or (e) amend this Section 10. No
termination or amendment of the Plan shall affect any outstanding Award unless expressly provided hereunder or as determined by the Board. Nothing in this Section 10 shall limit the Board's or
Committee's authority to take any action permitted pursuant to Section 3(c). The Plan shall continue in effect until the earlier of: (i) ten (10) years after the Effective Date,
(ii) its termination by the Board, or (iii) the date on which all of the shares of Common Stock available for issuance under the Plan have been issued and all restrictions on such shares
under the terms of the Plan, the Option Agreements and Restricted Stock Agreements have lapsed. 

SECTION 11.  STATUS OF PLAN

        With
respect to the portion of any Award that has not been exercised and any payments in cash, Common Stock or other consideration not received by a Grantee, a Grantee shall have no
rights greater than those of a general creditor of the Company unless the Committee shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Committee
may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver Common Stock or make payments with respect to Awards hereunder,  provided that the existence of
such trusts or other arrangements is consistent with the foregoing sentence. 

SECTION 12.  GENERAL PROVISIONS

        (a)   No Distribution; Compliance with Legal Requirements.    The grant of Awards and the issuance of shares of
Common Stock upon exercise of Awards shall be subject to compliance with all applicable requirements of federal (Canadian or United States, as applicable), provincial, state and foreign law 

10

 

with
respect to such securities. Awards may not be granted or exercised if the issuance of shares of Common Stock upon exercise would constitute a violation of any applicable federal (Canadian or
United States, as applicable), provincial, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Common Stock
may then be listed. In addition, no Award may be exercised unless: (i) a registration statement under the Act shall at the time of exercise of the Award be in effect with respect to the shares
of Common Stock issuable upon exercise of the Award, or (ii) in the opinion of legal counsel to the Company, the shares of Common Stock issuable upon exercise of the Award may be issued in
accordance with the terms of an applicable exemption from the registration requirements of the Act; provided, however, to the extent applicable, Awards must be granted and exercised in accordance with
the prospectus and registration requirements of applicable Canadian securities laws. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed
by Company's legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such shares as
to which such requisite authority shall not have been obtained. As a condition to the exercise of any Award, the Company may require the Grantee to satisfy any qualifications that may be necessary or
appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 

        (b)   Delivery of Stock Certificates.    Stock certificates issued under this Plan shall be deemed delivered for all
purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates by first class mail, addressed to the Grantee, at the Grantee's last known address on file with
the Company. 

        (c)   Other Compensation Arrangements; No Employment Rights.    Nothing contained in this Plan shall prevent the
Committee from adopting other or additional compensation arrangements, including trusts, and such arrangements as may be either generally applicable or applicable only in specific cases. The adoption
of this Plan and the grant of Awards do not confer upon any Grantee any right to continued employment or service with the Company or any Affiliate of the Company or interfere in any way with the right
of the Company or its Affiliates to terminate the Grantee's employment or service at any time. 

        (d)   "Market Stand-Off" Agreement.    In connection with any public offering by the Company of its
Common Stock, a Grantee, if requested in good faith by the Company and the managing underwriter of the Company's securities, shall not, directly or indirectly, offer, sell, pledge, contract to sell
(including any short sale), grant any option to purchase or otherwise dispose of any securities of the Company held by him (except for any securities sold pursuant to such registration statement) or
enter into any Hedging Transaction (as defined below) relating to any securities of the Company for a period determined by the managing underwriter. For these purposes,
"Hedging Transaction" means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including without limitation,
any put or call option) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Company's
Common Stock. 

        (e)   Trading Policy Restrictions.    Sale of Common Stock received pursuant to this Plan or upon exercise of an
Award under the Plan shall be subject to any insider-trading-policy-related restrictions, terms and conditions as may be established by the Committee, or in accordance with policies set by the
Committee, from time to time. 

        (f)    Conflict with Agreement.    In the event of a conflict between the terms and provisions of this Plan and the
terms and provisions of any Restricted Stock Agreement, Option Agreement or other award agreement, the terms and provisions of this Plan shall govern. 

11

 

SECTION 13.  EFFECTIVE DATE OF PLAN

        The
Plan is effective on                                    , 2007
(the "Effective Date"), the date on which the Board adopted the Plan, subject to
approval by the stockholders of the Company in the manner and within the time required under Section 422(b) of the Code and by the securities exchange or
over-the-counter market upon which the Common Stock is listed. Any increase in the maximum aggregate number of shares of Common Stock issuable under the Plan pursuant to
Section 3(a) shall be approved by stockholders of the Company within twelve (12) months of approval of such increase by the Board in accordance with applicable law. Subject to such
approvals by the stockholders and to the requirement that no shares of Common Stock may be issued hereunder
prior to such approval, Awards may be granted hereunder on and after adoption of the Plan by the Board.

LAB INTERNATIONAL INC.
  
    STOCK OPTION PLAN    
    

1.     PURPOSE  

        The purpose of this stock option plan (the "Plan") is to authorize the grant to service providers for LAB International Inc. (the "Corporation") of options
to purchase common shares ("shares") of the Corporation's capital and thus benefit the Corporation by enabling it to attract, retain and motivate service providers by providing them with the
opportunity, through share options, to acquire an increased proprietary interest in the Corporation. 

2.     ADMINISTRATION  

        The Plan shall be administered by the board of directors of the Corporation or a committee established by the board of directors for that purpose (the
"Committee"). Subject to approval of the granting of options by the board of directors or Cormnittee, as applicable, the Corporation shall grant options under the Plan. 

3.     SHARES SUBJECT TO PLAN  

        Subject to adjustment under the provisions of paragraph 12 hereof, the aggregate number of shares of the Corporation which may be issued and sold under the
Plan will not exceed 1,500,000 shares. The total number of shares which may be reserved for issuance to any one individual under the Plan shall not exceed 5% of the outstanding issue. The Corporation
shall not, upon the exercise of any option, be required to issue or deliver any shares prior to (a) the admission of such shares to listing on any stock exchange on which the Corporation's
shares may then be listed, and (b) the completion of such registration or other qualification of such shares under any law, rules or regulation as the Corporation shall determine to be
necessary or advisable. If any shares cannot be issued to any optionee for whatever reason, the obligation of the Corporation to issue such shares shall terminate and any option exercise price paid to
the Corporation shall be returned to the optionee. Any issue of options under the Plan is subject to the approval of the Toronto Stock Exchange (the "TSE") if the shares are listed on the TSE. 

4.     LIMITS WITH RESPECT TO INSIDERS  

	(a)
	The
maximum number of shares which may be reserved for issuance to insiders under the Plan, any other employer stock option plans or options for services, shall be 10% of the shares
issued and outstanding at the time of the grant (on a non-diluted basis),

	(b)
	The
maximum number of shares which may be issued to insiders under the Plan, together with any other previously established or proposed share compensation arrangements, within any one
year period shall be 10% of the outstanding issue. The maximum number of shares which may be issued to any one insider and his or her associates under the Plan, together with any other previously
established or proposed share compensation arrangements, within a one year period shall be 5% of the shares outstanding at the time of the grant (on a non-diluted basis).

	(c)
	Any
entitlement to acquire shares granted pursuant to the Plan, any other employer stock option plans, options for services or any other share compensation agreement, prior to the
optionee becoming an insider, shall be excluded for the purposes of the limits set out in paragraphs (a) and (b) above. 

1

 

5.     ELIGIBILITY  

        Options shall be granted only to service providers for the Corporation. The term "service providers for the Corporation" means (a) any full or
part-time employee or officer, or insider of the Corporation or any of its subsidiaries; (b) any other person or company engaged to provide ongoing management or consulting services
for the Corporation or any entity controlled by the Corporation (any person in (a) or (b) hereinafter referred to as an "Eligible Person"); (c) any registered retirement savings
plan established by such Eligible Person, or any corporation controlled by such Eligible Person, the issued and outstanding voting shares of which are, and will continue to be, beneficially owned,
directly or indirectly, by such Eligible Person and/or the spouse, children and/or grandchildren of such Eligible Person. The terms "insider", "controlled" and "subsidiary" shall have the meanings
ascribed thereto in the Company Manual of the Toronto Stock Exchange from time to time. Subject to the foregoing, the board of directors or Committee, as applicable, shall have full and final
authority to determine the persons who are to be granted options under the Plan and the number of shares subject to each option. 

6.     PRICE  

        The purchase price (the "Price") for the shares of the Corporation under each option shall be determined by the board of directors or Committee, as applicable, on
the basis of the market price, where "market price" shall mean the prior trading day closing price of the shares of the Corporation on the TSE if the shares are listed on the TSE or if the shares are
not listed on the TSE, on any other stock exchange on which the shares are listed or on any dealing network on which the shares are quoted for unlisted trading privileges, and where there is no such
closing price, "market price" shall mean the closing price on the last day on which a trade in the shares occurred on the TSE or if the shares are not listed on the TSE, on any other stock exchange on
which the shares are listed or on any dealing network on which the shares are quoted for unlisted trading privileges. In no event shall the Price be less than the market price on the TSE, if the
shares of the Corporation are then listed on such exchange. 

7.     PERIOD OF OPTION AND RIGHTS TO EXERCISE  

        Subject to the provisions of this paragraph 7 and paragraphs 8, 9, 10 and 17 below, options will be exercisable in whole or in part, and from time to time,
during the currency thereof. Options shall not be granted for a term exceeding ten years. The shares to be purchased upon each exercise of any option (the "optioned shares") shall be paid for in full
at the time of such exercise. Except as provided in paragraphs 8, 9, 10 and 17 below, no option which is held by a service provider may be exercised unless the optionee is then a service provider for
the Corporation. 

8.     CESSATION OF PROVISION OF SERVICES  

        Subject to paragraph 10 below, if any optionee who is a service provider shall cease to be a service provider for the Corporation for any reason (except as
otherwise provided in paragraphs 9 or 10) the optionee may, but only within the period of ninety days next succeeding such cessation and in no event after the expiry date of the optionee's
option, exercice the optionnee's option. 

9.     DEATH OF OPTIONEE  

        Subject to paragraph 10 below, in the event of the death of an optionee during the currency of the optionee's option, the option theretofore granted to the
optionee shall be exercisable within, but only within, the period of one year next succeeding the optionee's death, and in no event after the expiry date of the option. Before expiry of an option
under this paragraph 9, the board of directors or Committee, as applicable, shall notify the optionee's representative in writing of such expiry. 

2

 

10.   EXTENSION OF OPTION  

        In addition to the provisions of paragraphs 8 and 9, the board of directors or Committee, as applicable, may extend the period of time within which an option held
by a deceased optionee may be exercised or within which an option may be exercised by an optionee who has ceased to be a service provider for the Corporation, but such an extension shall not be
granted beyond the original expiry date of the option. Any extensions of options granted under this Plan are subject to applicable regulatory approval. 

11.   NON-TRANSFERABILITY AND ASSIGNABILITY OF OPTION  

        No option granted under the Plan shall be transferable or assignable by an optionee otherwise than by will or by the laws of descent and distribution, and such
option shall be exercisable, during an optionee's lifetime, only by the optionee. 

12.   ADJUSTMENTS IN SHARES SUBJECT TO PLAN  

        The aggregate number and kind of shares available under the Plan shall be appropriately adjusted in the event of a reorganization, recapitalization, stock split,
stock dividend, combination of shares, merger, consolidation, rights offering or any other change in the corporate structure or shares of the Corporation. The options granted under the Plan may
contain such provisions as the board of directors or Committee, as applicable, may determine with respect to adjustments to be made in the number and kind of shares covered by such options and in the
option price in the event of any such change. 

13.   AMENDMENT AND TERMINATION OF THE PLAN  

        The board of directors or Committee, as applicable, may at any time amend or terminate the Plan, but where amended, such amendment is subject to regulatory
approval, including, without limitation, the approval of the TSE if the shares are listed on the TSE. 

14.   EFFECTIVE DATE OF THE PLAN  

        The Plan becomes effective on the date of its approval by the shareholders of the Corporation. 

15.   EVIDENCE OF OPTIONS  

        Each option granted under the Plan shall be embodied in a written option agreement between the Corporation and the optionee which shall give effect to the
provisions of the Plan. 

16.   EXERCISE OF OPTION  

        Subject to the provisions of the Plan and the particular option, an option may be exercised from time to time by delivering to the Corporation at its registered
office a written notice of exercise specifying the number of shares with respect to which the option is being exercised and accompanied by payment in cash or certified cheque for the full amount of
the purchase price of the shares then being purchased, 

        Upon
receipt of a certificate of an authorized officer directing the issue of shares purchased under the Plan, the transfer agent is authorized and directed to issue and countersign

	the
Corporation seeks approval from its shareholders for a transaction which, if completed, would constitute an Acceleration Event; or

Plan, as to all or any of the optioned shares in respect of which such option has not previously been exercised (regardless of any vesting restrictions), during the period specified in the notice (but
in no event later than the expiry date of the option), so that the optionee may participate in such transaction, offer or proposal; and (ii) the board of directors or Committee, as applicable,
may require the acceleration of the time for the exercise of the said option and of the time for the fulfilment of any conditions or restrictions on such exercise. 

        For
these purposes, an Acceleration Event means:

50% of the outstanding voting securities of the Corporation, by means of a take-over bid or otherwise;

	any
consolidation or merger of the Corporation in which the Corporation is not the continuing or surviving corporation or pursuant to which shares of the Corporation would be
converted into cash, securities or other property, other than a merger of the Corporation in which shareholders immediately prior to the merger have the same proportionate ownership of stock of the
surviving corporation immediately after the merger;

distributions therefrom or thereon) other than in respect of optioned shares in respect of which the optionee shall have exercised the option to purchase hereunder and which the optionee shall have
actually taken up and paid for. 

20.   GOVERNING LAW  

        This
Plan shall be construed in accordance with and be governed by the laws of the Province of Ontario and shall be deemed to have been made in said Province, and shall be in accordance
with all applicable securities laws.
