or service relationship is terminated, (2) the date the Participant receives notice of termination, or (3) the date the Participant ceases to actively provide services (regardless of the reason for such termination and whether or not the

determine when the Participant is no longer actively providing services for purposes of the Restricted Share Units (including whether the Participant may still be considered to be providing services while on a leave of absence). 


 

	Section 1.8	Incentive Stock Option (ISO) Plan 

  

	(1)	Options granted under this Section 1.8 may be designated as “incentive stock options” (“ISOs”) within the meaning of section 422 of the United States Internal Revenue Code of 1986, as
amended (the “US Tax Code”). Any Options not granted under this Section 1.8 as ISOs shall be granted as nonqualified stock options for the purposes of the US Tax Code. Any Options designated as ISOs shall be governed by this
Section 1.8 and, to the extent of any inconsistency between the terms of this Section 1.8 and the Plan, the terms of this Section 1.8 shall govern. 


 

	(2)	The class of person who may be granted ISOs under this Section 1.8 shall, in addition to the limitations otherwise imposed by the Plan, be limited to those persons who are “employees” (within the meaning
of section 3401(c) of the US Tax Code) of the Corporation or its “parent” or “subsidiary” corporations within the meaning of section 424(e) and (f), respectively, of the US Tax Code. 


 

	(3)	The exercise price of any Option granted under this Section 1.8 as an ISO shall not be less than the fair market value of the Shares at the time such Option is granted (determined in accordance with
Section 422(c)(1) of the U.S. Tax Code and any regulations promulgated thereunder). 

  

	(4)	The aggregate number of Shares over which Options may be granted under this Section 1.8 or under the other provisions of this Plan to all Participants during the term of the Plan shall not exceed the number of
shares reserved under the Plan pursuant to Section 1.5. Notwithstanding any other provision of this Section 1.8, any Option granted hereunder shall cease to be an ISO, and shall thereafter constitute a nonqualified stock option for the
purposes of the US Tax Code, if this Plan is not approved by the shareholders of the Corporation within 12 months of its adoption. Subject in all instances to any shorter exercise period or option term set forth in the Plan or any Option Agreement,
any Option granted under this Section 1.8 as an ISO shall not be exercisable after the expiration of ten years from the Date of Grant of such ISO. 

  

	(5)	 To the extent that the aggregate fair market value of Shares with respect to which ISOs are exercisable for the
first time by a Participant during any calendar year (under all plans or schemes of the Corporation or its “parent” or “subsidiary” corporations within 



  
 8 









	 	
the meaning of sections 424(e) and (f), respectively, of the US Tax Code) exceeds US$100,000 as determined at the time of grant, such Options shall be treated, to the extent of the excess, as
nonqualified stock options for the purposes of the US Tax Code. Furthermore, not more than 25% of the total number of Shares available for issuance under the Plan may be made subject to Options to any individual in the aggregate in any one fiscal
year of the Company, such limitation to be applied in a manner consistent with the requirements of, and only to the extent required for compliance with, the exclusion from the limitation on deductibility of compensation under section 162(m) of the
US Tax Code. 

  

	(6)	No ISO may be granted to an individual if, at the time of the proposed grant, such individual owns (or is deemed to own pursuant to the US Tax Code) stock possessing more than ten per cent. of the total combined voting
power of all classes of stock of the Corporation (or its “parent” or “subsidiary” corporations within the meaning of sections 424(e) and (f), respectively, of the US Tax Code) unless (a) the exercise price of such ISO is at
least 110 per cent of the fair market value of a Share at the Date of Grant of such ISO and (b) such ISO is not exercisable after the expiration of five years from the Date of Grant of such ISO. 


 

	(7)	If any Option granted under this Section 1.8 is exercised more than three (3) months after the date that the Participant was last employed by the Corporation (or by its “parent” or
“subsidiary” corporations within the meaning of sections 424(e) and (f), respectively, of the US Tax Code), or in case the Participant becomes “disabled” (as defined by section 422(c)(6) of the US Tax Code) more than twelve
(12) months after the date that the Participant was last employed by the Corporation (or by its “parent” or “subsidiary” corporations within the meaning of sections 424(e) and (f), respectively, of the US Tax Code), then
such Option shall be treated as a nonqualified stock option for purposes of the US Tax Code. 

  

	(8)	Subject in all instances to the transfer restrictions contained elsewhere in the Plan and in any Option Agreement, any Option granted under this Section 1.8 as an ISO may not be transferred by the Participant other
than by will or the applicable laws of descent and distribution, and any such Option granted under this Section 1.8 as an ISO shall only be exercisable, during the lifetime of the Participant, by the Participant. 


 

	(9)	Shares shall not be issued pursuant to the exercise of any Option granted under this Section 1.8 unless the exercise of the Option and the issuance and delivery of such Shares shall comply with all relevant
provisions of law, involving, without limitation, the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended, applicable State securities laws, and the requirements of any stock exchange
upon which Shares may then be listed, and, at the discretion of the Board, shall be further subject to approval of counsel for the Corporation with respect to such compliance. None of the Corporation or any of its subsidiaries or affiliates shall
have any obligation to register any Shares under the Securities Act or any applicable State law. Any stock certificates evidencing any Share issued pursuant to this Section 1.8 may bear a legend indicating that the transferability of the
certificate and the Shares are restricted and subject to terms and conditions contained in this section or otherwise. 


  
 9 









	(10)	An ISO may not be granted after the earlier of the date that is (a) ten years after the date that the Plan is approved by the shareholders of the Corporation, or (b) ten years after the date that the Plan is
adopted by the board of directors of the Corporation. 

  

	(11)	By accepting an ISO, a Participant agrees to notify the Company in writing within ten days after such Participant makes a “disqualifying disposition” (as described in Sections 421, 422 and 424 of the Code and
regulations thereunder) of any Shares acquired pursuant to the exercise of that ISO. A disqualifying disposition is generally any disposition occurring on or before the later of (a) the date two years following the date the ISO was granted, or
(b) the date one year following the date the ISO was exercised. 

 ARTICLE 2 

FAIR VALUE 
  

	Section 2.1	Fair Value 

  

	(1)	Subject to this Article 2, unless otherwise determined by the Board, the purchase price of Shares subject to an Option granted pursuant to the Plan shall be determined by the Board on the Date of Grant. Unless otherwise
determined by the Board, in the event that the Shares are not listed on any stock exchange or market, the purchase price of Shares subject to an Option granted under the Plan shall be not less than 100% of the fair market value of the Shares as
determined in good faith by the Board at the Date of Grant, which fair market value will be the “Fair Value” for the purposes of this Plan. The Board may consider any evidence that it, in its sole discretion, determines to be helpful to it
in determining Fair Value. The Board may determine a new Fair Value from time to time as, in its sole discretion, is warranted by the circumstances. 

  

	(2)	If the Corporation is a Public Company, “Fair Value” for the purposes of this Plan will be equal to the closing market price of the Shares on the TSX or other relevant stock exchange (as determined by the
Board) on the last trading day preceding the Date of Grant. If there is no trading on that date, the “Fair Value” will be the average of the bid and ask on the last trading date preceding the Date of Grant.

the Date of Grant. No Option may be exercised after its stated expiration. 

  

	(2)	The Board will determine when any Option will become exercisable and may determine that an Option will be exercisable in instalments. If not otherwise determined by the Board, an Option will vest as to one-quarter of

Participant which has vested on or prior to the Termination Date will cease to be exercisable immediately upon the date on which the Corporation or an Affiliated Entity gives the Participant notice of termination of employment, unless otherwise
determined by the Board.

date of the Participant’s death, but only to the extent that the Options were, by their terms, vested on the date of death. 

  

	(6)	On the Participant’s Date of Disability, the Participant may exercise the Participant’s Options, pursuant to Section 4.1, within 180 days after the Participant’s Date of Disability, but only to the
extent that the Options were, by their terms, vested on the Participant’s Date of Disability.

Participant. No Participant may deal with any Options or any interest in them or Transfer any Options except in accordance with this Plan. A purported Transfer of any Options in violation of this Plan will not be valid and the Corporation will not
issue any Share upon the attempted exercise of those Options. Subject to Applicable Rules, the Board may establish rules and procedures permitting the Transfer of Options in circumstances and on terms determined by the Board. The obligations of each

 EXERCISE
OF OPTIONS 
  

	Section 4.1	Exercise of Option and Payment of Option Price 

 Subject to the provisions of the Plan,
an Option maybe exercised from time to time by delivery to the Corporation at its office of a written notice of exercise substantially in the form attached hereto as Schedule “B”, addressed to the Secretary of the Corporation specifying
the number of Shares with respect to which the Option is being exercised (the “Notice of Exercise”). The purchase price of each Share purchased under an Option shall, at the option of the Participant, be paid by bank draft or
certified cheque. Upon receipt by the Corporation of payment in full and the completed Notice of Exercise, but subject to this Plan, the number of Shares in respect of which the Option is exercised will be issued as fully paid and non-assessable.

 In the event that the Shares are not listed on a stock exchange as at the date of an exercise of an Option, it shall be a condition

limitation, 

  

	 	(a)	a description of the material business terms of the Offer;

	 	(c)	the consequences of acceptance. 

  

	(2)	The Participant must sell any Shares held by him to the Offeror in accordance with the Offer and this Plan. The Corporation is hereby irrevocably appointed the agent and attorney of the Participants for the purpose of

 The terms and provisions of the Plan and any Option shall apply mutatis mutandis to any Intermediary as if such
Intermediary were a Participant. The obligations of each Intermediary pursuant to the Plan and/or any Option shall be binding on the Participant on behalf of or for the benefit of whom the Intermediary acts (the “Beneficiary”), and
on such Beneficiary’s successors, assigns, heirs, executors or administrators, as applicable. The Participant shall do such acts and things and execute such instruments as are necessary or desirable to cause the Intermediary to comply with the
terms and provisions of the Plan and/or any Option.

Entity shall agree: 

  

	 	(i)	to advise the Corporation and the Remaining Shareholders promptly upon any change in its beneficial ownership or interest; and 

  

	 	(ii)	to be bound by all of the terms, covenants, conditions and agreements contained in this Plan as fully and effectively as if the Entity had originally executed an Option Agreement as the Transferring Participant; and


  

	 	(d)	an agreement executed by the Transferring Participant in favour of the Corporation and the Remaining Shareholders pursuant to which the Transferring Participant shall: 


 

	 	(i)	agree not to dispose of or transfer effective control of the Entity for so long as the Entity shall own any Shares; and

[RESERVED] 

ARTICLE 8 
 GENERAL

  

	Section 8.1	Merger or Sale 

 If there is: 
  

	(1)	an amalgamation or arrangement involving a change of control, or a consolidation or merger in which the Corporation is not the surviving corporation, or a transaction that results in the acquisition of substantially all
of the Corporation’s outstanding Shares by a single person, entity or group of persons or entities acting in concert (a “combination”); 

  

	(2)	the sale or transfer of all or substantially all of the assets of the Corporation; or 

  

	(3)	a reorganization, dissolution or liquidation of the Corporation, 

 the Board, or the Board of any corporation
assuming the obligations of the Corporation, will, having regard to its fiduciary duties and the best interests of the Corporation, as to outstanding Awards either: 
  

	(4)	provide that the Awards are assumed, or rights equivalent to the Awards are substituted, by the acquiring or succeeding corporation (or an affiliate); 


  
 16 









	(5)	upon written notice to Participants, provide that all unexercised Awards (both vested and unvested) will terminate immediately prior to the consummation of the merger, consolidation, acquisition, reorganization,
liquidation, sale or transfer unless those Awards which have vested are exercised by respective Participants within a specified number of days following the date of the notice; 


 

	(6)	in case of a combination under the terms of which holders of Shares will receive cash and/or other consideration for each Share surrendered in the combination, provide for the delivery to each Participant of the cash
and/or other consideration that the Participant would have received had the Participant exercised all of the Participant’s outstanding vested Awards immediately prior to the combination (less the amount the Participant would have been required
to pay to the Corporation on that exercise, in cash and/or in a portion of any other consideration having a fair value equal to the amount), in exchange for the termination of all of the Participant’s vested and unvested Awards; or


  

	(7)	take such other actions and combinations of the foregoing actions as it deems fair and reasonable under the circumstances. 


In any case, the Board may, in its discretion, advance any waiting, vesting or instalment period and exercise date. 

 

	Section 8.2	Substitute Awards 

 The Corporation may grant Awards under the Plan in substitution for
awards held by employees or directors or consultants of another corporation who become Eligible Persons as the result of a merger or consolidation of the employing corporation with the Corporation, or as a result of the acquisition by the

	Section 8.3	Closing Procedures 

 If a purchase and sale of Shares is made pursuant to this Agreement,
the following will apply, subject to any express provisions to the contrary: 
  

	(1)	Payment of Purchase Price and Delivery of Certificates. Payments on account of the purchase price will be made by negotiable cheque certified by a Canadian chartered bank or trust company or official bank draft
drawn on a Canadian chartered bank or by a comparable financial authority, provided that if the Corporation is purchasing Shares and the Board determines, in its sole discretion, that payment in full would adversely affect the cash flow of the
Corporation then, the Board may elect to make payment in whole or in part by promissory note which will provide for payment within a period (determined by the Board) of no greater than 12 months after the completion of the purchase and will bear
interest at the prime rate as established from time to time by the Corporation’s principal Canadian bankers on the date of completion of the purchase. 


  
 17 









	(2)	Date and Time of Closing. If the date for completion of any transaction of purchase and sale falls on a day that is not a Business Day, the transaction will be completed on the first Business Day following that
date. Closing will take place at 11:00 a.m. on the date for completion at the then head office of the Corporation. 

  

	(3)	Title. The acceptance by the vendor of payment (including an agreement to pay) for the Shares being purchased and sold will constitute a representation and warranty by the vendor that the vendor has good and
marketable title to the Shares, free and clear of any lien, charge, pledge, encumbrance, security interest or adverse claim, except this Agreement. In addition, the vendor will deliver to the purchaser all documents, instruments and releases and do
all acts and things as the purchaser may reasonably request, whether before or after completion of the transaction, to vest title in the purchaser. 

  

	Section 8.4	Attorney and Voting Trust 

 Each Participant hereby appoints the Chief Financial Officer
of the Corporation, or, if the Chief Financial Officer is not a resident Canadian for tax purposes, such other resident Canadian (for tax purposes) officer of the Corporation as specified by the Board, (the “Trustee”) as the
Participant’s attorney with respect to Shares held by such Participant with full power of substitution, in the name of the Participant but on behalf of and at the expense of the Trustee, to execute and deliver all deeds, transfers, assignments
and assurances necessary to vote or act upon matters related to the Shares, including, without limitation, all matters set forth in Section 5.4. and including the delivery of the Shares to the Offeror in accordance with Section 5.4, and,
in respect of any Non-Voting Common Shares held by the Participant, any class vote of the holders of Non-Voting Common Shares. The appointment, being coupled with an interest, is irrevocable by the Participant and will not be revoked by the
insolvency, bankruptcy, death, incapacity, dissolution, liquidation or other termination of the existence of the Participant. The Trustee will also vote or cause to be voted all of the Participant’s Shares at all times and in accordance with
the vote of holders of a majority of Shares of the Corporation. The Participant hereby ratifies and confirms and agrees to ratify and confirm all that the Trustee may lawfully do or cause to be done by virtue of such appointment and power. The
Participant shall have no claim or cause of action against the Corporation or the Trustee, or against any third party, as a result of the Trustee so acting as its attorney. The power of attorney granted hereunder shall be automatically terminated
upon the effective date of a registration statement filed by the Corporation, or its successor in interest, with the U.S. Securities and Exchange Commission, or upon the issuance to the Corporation, or its successor in interest, of a receipt for a
final prospectus by the Ontario Securities Commission or any other corresponding securities agency.

	Section 8.5	Notation on Share Certificates 

 So long as the Corporation is not a Public Company, all
Share certificates issued subsequently will have the following statement conspicuously noted on them: 
 “There are restrictions on the
right to transfer the shares represented by this certificate as set out in the BTI Systems Inc. Amended and Restated 2012 Stock Option Plan, as the same may be amended or restated from time to time, and such shares may not be pledged, sold or
otherwise transferred except in accordance with the BTI Systems Inc. Amended and Restated 2012 Stock Option Plan.” 
  

	Section 8.6	Share Certificates 

 So long as the Corporation is not a Public Company, any certificate
representing Shares purchased by a Participant upon the exercise of an Option or issued to the RSU Participant must be endorsed in blank for transfer by the Participant and will be held by the Corporation as custodian for the Participant. The
Corporation will issue to the Participant a Deposit Receipt. 
  

	Section 8.7	Beneficial Ownership 

 Notwithstanding the deposit of the Shares with the Corporation,
the Shares will continue to be beneficially owned by the Participant in respect of whom the Shares were issued. The Corporation will hold the Shares as custodian for that Participant in accordance with this Agreement, and that Participant will,
except as otherwise expressly provided in this Agreement, continue to enjoy all the rights of beneficial ownership relating to the Shares. 
  

	Section 8.8	Dividends, Changes in Shares, etc. 

 For purposes of the Options: 

 

	(1)	if the Corporation receives any certificates for securities issued by way of stock split or stock dividend upon or in exchange for any Shares held by it under this Agreement, the Corporation will hold the certificates
in accordance with the terms of this Agreement and will issue Deposit Receipts representing the certificates to the registered holders of the then outstanding Deposit Receipts entitled to those certificates; and 


 

	(2)	all cash dividends and all other monies that may become due and payable to the Participant, whether by reason of dissolution, liquidation, disposition or otherwise, will be paid directly to the Participant, according to
their respective interests as shown on the securities register of the Corporation. 

  

	Section 8.9	Capital Adjustments 

 If there is any change in the outstanding Shares by reason of a
stock dividend or split, recapitalization, consolidation, combination or exchange of shares, or other fundamental corporate change, other than the issuance of Shares by the Corporation for consideration, the Board may, subject to any prior approval
required of any applicable regulatory authority and subject to Section 8.1, make an appropriate substitution or adjustment in: 
  

	(1)	the exercise price of any unexercised Options; 

  

	(2)	the number or kind of Shares reserved for issuance pursuant to this Plan; or 


  
 19 









	(3)	the number or kind of Shares subject to unexercised Options previously granted and in the exercise price of those unexercised Options; 


provided, however, that no substitution or adjustment will obligate the Corporation to issue or sell fractional Shares. The determination of the Board, as to
any adjustment or as to there being no need for adjustment, will be final and binding on all parties. 
  

	Section 8.10	No Special Employment Rights 

 Nothing contained in the Plan or in any Award will confer
upon any Participant any right with respect to the continuation of the Participant’s employment by the Corporation or interfere in any way with the right of the Corporation at any time to terminate that employment or to increase or decrease the
compensation of the Participant. 
  

	Section 8.11	Other Employee Benefits 

 The amount of any compensation deemed to be received by a
Participant as a result of the exercise of an Option and settlement of an RSU or the sale of Shares received upon an exercise of an Award will not constitute compensation with respect to which any other employee benefits of that Participant are
determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined by the Board. 

 

	Section 8.12	Non-Exclusivity 

 Nothing contained in this Plan will prevent the Board from adopting
other or additional compensation arrangements for the benefit of any Eligible Person or Participant, subject to any required regulatory or shareholder approval. 
  

	Section 8.13	Authorization of Sub-Plans 

 The Board may from time to time establish one or more
sub-plans under the Plan for purposes of satisfying applicable blue sky, securities or tax laws of various jurisdictions. The Board shall establish such sub-plans by adopting supplements to this Plan containing (a) such limitations on the
Board’s discretion under the Plan as the Board deems necessary or desirable or (b) such additional terms and conditions not otherwise inconsistent with the Plan as the Board shall deem necessary or desirable. All supplements adopted by the
Board shall be deemed to be part of the Plan, but each supplement shall apply only to Participants within the affected jurisdiction and the Corporation shall not be required to provide copies of any supplement to Participants in any jurisdiction
which is not the subject of such supplement. In connection with the foregoing, the Corporation has hereby established the BTI Systems 2012 Stock Incentive Plan Sub-Plan for California Participants, included herewith as Exhibit A to the Plan. 

 

	Section 8.14	Effect of Termination 

 If this Plan is terminated, the provisions of this Plan and any
administrative guidelines and other rules adopted by the Board and in force when this Plan is terminated, will continue in effect as long as any Award, or any right pursuant to an Award, remains outstanding. However, notwithstanding the termination
of this Plan, the Board may make any amendments to this Plan, or to any outstanding Award, that it would be entitled to make if this Plan were still in effect. 

  
 20 









	Section 8.15	Compliance with Applicable Legislation and Other Requirements 

  

	(1)	The Corporation is not obligated by this Plan or any grant under it to, and will not, take any action required, permitted or otherwise contemplated by this Plan except in accordance with Applicable Rules. The Board may
postpone or adjust any exercise of any Award or the issue of any Shares pursuant to this Plan or refrain from taking any action or exercising any right required, permitted or contemplated by the Plan as the Board in its discretion may deem necessary
in order to permit the Corporation to ensure compliance of this Plan or the issuance of Shares pursuant to it with Applicable Rules. 

  

	(2)	If the Shares are listed on a stock exchange, the Corporation will have no obligation to issue any Shares pursuant to this Plan unless the Shares have been duly listed, upon official notice of issuance, on that stock
exchange. 

  

	(3)	If Applicable Rules prevent the exercise of an Option, the settlement of an RSU or the issue of a Share, the Board may, in addition to the rights referred to above, choose to address the economic value of a
Participant’s rights in whatever manner it deems to be reasonable in the circumstances, and action taken by the Corporation in consequence of that determination will be deemed to have satisfied the Corporation’s obligations as they would
otherwise have existed. 

  

	(4)	The Board shall endeavor in good faith to assure that that the terms of any Options shall be such that the Participant to whom such Options are awarded shall not be subject to the tax or interest charges imposed by
Section 409A(a)(1) of the US Tax Code. No Option shall provide for deferral of compensation that does not comply with Section 409A of the US Tax Code, unless the Board, at the time of grant or any amendment or modification, specifically
provides that the Option is not intended to comply with Section 409A of the US Tax Code. The Plan and each Option are hereby modified and limited as necessary to comply with applicable requirements of Section 409A of the US Tax Code.
Notwithstanding the foregoing, neither the Corporation nor any member of the Board shall have any liability to a Participant, or any other party, if an Option that is intended to be exempt from, or compliant with, Section 409A of the US Tax
Code is not so exempt or compliant or for any action taken by the Board. 

  

	Section 8.16	Participation in the Plan 

 The participation of any Participant in the Plan is entirely
voluntary and not obligatory, has not been induced by any expectation of future or continued employment, appointment or engagement by the Corporation or any of its subsidiaries, and shall not be interpreted as conferring upon such Participant any
rights or privileges other than those rights and privileges expressly provided in the Plan. The Plan does not provide any guarantee against any loss which may result from fluctuations in the market value of the Shares. The Corporation does not
assume responsibility for the income or other tax consequences for the Participants and they are advised to consult with their own tax advisors. 

  
 21 









	Section 8.17	Governing Law 

 This Plan shall be construed in accordance with the laws of the Province
of Ontario, without regard to the conflict of laws principles of such jurisdiction, and the federal laws of Canada applicable therein. 
  

	Section 8.18	Effective Date 

 The Plan is effective as of March 28, 2013, the date the Plan was
approved and adopted by the Board, and amended as of November 8, May 14, 2014, and January 24, 2016.

Any grant of Options made under the Plan to a recipient who is a resident of the State of California on the date of grant (a
“California Participant”) shall be subject to the following additional limitations, terms and conditions: 
 1.1 Additional Limitations
on Options. 
 (a) Maximum Duration of Options and Plan. Subject to such shorter period of time as may be provided in the Plan or

(b) Minimum Exercise Period Following Termination. Unless a California Participant’s employment by the Corporation or any
subsidiary of the Corporation is terminated for cause, in the event of termination of employment of such California Participant, he or she shall have the right to exercise an Option to the extent that he or she was otherwise entitled to exercise
such Option on the date employment terminated, as follows: (i) at least six months from the date of termination, if termination was caused by such California Participant’s death or “permanent and total disability” (within the
meaning of Section 22(e)(3) of the Code) and (ii) at least 30 days from the date of termination, if termination was caused other than by such California Participant’s death or “permanent and total disability” (within the
meaning of Section 22(e)(3) of the Code). 
 1.2 Maximum Number of Shares. The total number of shares in the Corporation which may be issued to
California Participants under the Plan shall not exceed the number of shares determined under Section 1.5 of the Plan.

the issuer’s equity 







 
securities without the receipt of consideration by the issuer, proportionate adjustments shall be made as appropriate to (i) the number and class of securities available for award under the
Plan and the per-participant share limit, (ii) the number and class of securities, vesting schedule and exercise price per share subject to each outstanding Option and (iii) the number of shares allocated to an employee, director, manager

of descent and distribution, and during the life of the California Participant, shall be purchasable only by the California Participant.

event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder
from time to time.

2. Restricted Share Units. 

(a) Grant. Restricted Share Units may be granted at any time and from time to time as determined by the Administrator. After the

Units and the form of payout, which, subject to Section 2(a) hereof, may be left to the discretion of the Administrator. Until the Shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Restricted Share Units to acquire Shares. 
 (b) Vesting Criteria and Other Terms. The
Administrator shall set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Share Units that will be paid out to the Participant. The Administrator may set vesting
criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment), or any other basis determined by the Administrator in its discretion. 

(c) Earning Restricted Share Units. Upon meeting the applicable vesting criteria, the Participant shall be entitled to receive a
payout as specified in the Award Agreement. Notwithstanding the foregoing, at any time after the grant of Restricted Share Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a
payout. 

  
 -4- 








 (d) Form and Timing of Payment. Payment of earned Restricted Share Units shall be
made as soon as practicable after the date(s) set forth in the Award Agreement. The Administrator, in its sole discretion, but only as specified in the Award Agreement, may pay earned Restricted Share Units in cash, Shares, or a combination thereof.
If the Award Agreement is silent as to the form of payment, payment of the Restricted Share Units may only be in Shares. 
 (e)
Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Share Units shall be forfeited to the Company. 

3. Leaves of Absence/Transfer Between Locations/Change of Status. Awards will be subject to the Company’s leave of absence policy
adopted by the Administrator. A Participant will not cease to be a Service Provider in the case of (i) transfers between locations of the Company or other members of the Company Group, or (ii) a change in status from Employee to Consultant
or vice versa. 
 4. Part-Time Service. Unless otherwise required by Applicable Laws, if as a condition to being permitted to
work on a less than full-time basis, the Participant agrees that any service-based vesting of Awards granted hereunder shall be extended on a proportionate basis in connection with such transition to a less than a full-time basis, vesting shall be
adjusted in accordance with such agreement. Such vesting shall be proportionately re-adjusted prospectively in the event that the Employee subsequently becomes regularly scheduled to work additional hours of service. 

5. Non-Transferability of Awards. Except as determined otherwise by the Administrator in its sole discretion, Awards may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant (or the
Participant’s guardian or legal representative). 
 6. Tax Provisions. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such earlier
time as any Tax Obligations are due, the Company and/or any entity in the Company Group will have the power and the right to deduct or withhold, or require a Participant to remit to the Company and/or the appropriate entity in the Company Group, an
amount sufficient to satisfy all Tax Obligations. 
 (b) Withholding Arrangements. The Administrator, in its sole discretion and
pursuant to such procedures as it may specify from time to time, may designate the method or methods by which a Participant may satisfy such Tax Obligations. As determined by the Administrator in its discretion from time to time, these methods may
include one or more of the following (A) paying cash, (B) having the Company withhold otherwise deliverable cash or Shares having a fair market value equal to the Tax Obligations, (C) delivering to the Company already-owned Shares
having a fair market value equal to the Tax Obligations, (d) selling a sufficient number of Shares otherwise deliverable to the Participant through such means as the 

  
 -5- 








 
Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the Tax Obligations, (e) retaining from salary or other amounts payable to the Participant
cash having a sufficient value to satisfy the Tax Obligations, or (f) any other means which the Administrator, in its sole discretion, determines to both comply with Applicable Laws, and to be consistent with the purposes of the Plan. The
amount of Tax Obligations will be deemed to include any amount that the Administrator agrees may be withheld at the time the election is made. 

(c) Compliance with Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the
application of, or comply with, the requirements of Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A, except as otherwise determined in
the sole discretion of the Administrator. Each payment or benefit under this Plan and under each Award Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. The Plan, each
Award and each Award Agreement under the Plan is intended to be exempt from or otherwise meet the requirements of Section 409A and will be construed and interpreted, including but not limited with respect to ambiguities and/or ambiguous terms,
in accordance with such intent, except as otherwise specifically determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Section 409A the Award will be
granted, paid, settled or deferred in a manner that will meet the requirements of Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A. 

7. Adjustments; Dissolution or Liquidation; Merger or Change in Control. Notwithstanding anything in the Plan to the contrary, this
Section 8 shall apply to all grants of Restricted Share Units. 
 (a) Changes in Capitalization. Subject to any required
action by the stockholders of the Company, the number of shares covered by each outstanding Award shall be proportionately adjusted for any increase or decrease in the number of issued shares resulting from a stock split, reverse stock
split, stock dividend, combination or reclassification of the shares, or any other increase or decrease in the number of issued shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible
securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as
expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price
of Shares subject to an Award. Except as otherwise expressly provided herein or pursuant to an Award Agreement, no adjustment of any Award shall be made for cash dividends or other rights for which the record date occurs
prior to the date issuance of any Shares subject to such Award. 
 (b) Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Administrator may provide that any Company forfeiture rights
applicable to any Award shall lapse 100%, and that 

  
 -6- 








 
any Award vesting shall accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously vested,
an Award will terminate immediately prior to the consummation of such proposed action. 
 (c) Change in Control. Section 8.1 of
the Plan shall not apply to grants of Restricted Share Units and instead this Section 7(c) will apply to Restricted Share Units. In the event of a merger, amalgamation or arrangement involving a change of control of the Company with or into
another corporation or entity or a Change in Control, each outstanding Award shall be assumed or an equivalent Award substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Awards, the Participant shall fully vest in such Awards which would not otherwise be vested. For purposes of this paragraph, an Award shall be considered assumed if, following the merger or Change
in Control, the award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the transaction, the consideration (whether stock, cash, or other securities or property) received in the transaction by holders
of the Company’s common stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the
consideration to be received, for each Share and each unit/right to acquire a Share subject to the Award to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by
holders of the Company’s common stock in the merger or Change in Control. 
 8. No Effect on Employment or Service. Neither the
Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider, nor will they interfere in any way with the Participant’s right or the employing entity’s
right to terminate such relationship at any time, with or without cause. A Participant’s rights, if any, in respect of or in connection with any Award are derived solely from the discretionary decision of the Company to permit
the Participant to participate in the Plan and to benefit from a discretionary Award. By accepting an Award hereunder, a Participant expressly acknowledges and agrees that there is no obligation on the part of the Company to
continue the Plan and/or grant any additional Awards. Any Award granted hereunder is not intended to be compensation of a continuing or recurring nature, or part of a Participant’s normal or expected compensation, and in no way represents any
portion of a Participant’s salary, compensation, or other remuneration for purposes of pension, benefits, severance, redundancy, resignation or any other purpose. 

9. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. The granting of Awards and the issuance and delivery of Shares under the Plan shall be subject to all Applicable
Laws, and to such approvals by any governmental agencies or national securities exchanges as may be required. Shares will not be issued pursuant to the exercise or vesting of an Award unless the exercise or vesting of such Award and the issuance and
delivery of such Shares will comply with Applicable Laws, and may be further subject to the approval of counsel for the Company with respect to such compliance. 

  
 -7- 








 (b) Investment Representations. As a condition to the payout of an Award, the Company may
require the person receiving the Shares upon vesting, to render to the Company a written statement containing such representations and warranties as, in the opinion of counsel for the Company, may be required to ensure compliance with any of the
aforementioned relevant provisions of law, including a representation that the Shares are being acquired only for investment and without any present intention to sell or distribute such Shares, if, in the opinion of counsel for the Company, such a
representation is required. 
 10. Miscellaneous. 

(a) Severability. If a court of competent jurisdiction holds any provision invalid and unenforceable, the remaining provisions of the
Plan shall continue in effect. 
 (b) Construction. Captions and titles contained herein are for convenience only and shall not
affect the meaning or interpretation of any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be
exclusive, unless the context clearly requires otherwise. 
 (c) Clawback. An Award granted under the Plan will be subject to any
provisions of Applicable Laws providing for the recoupment or clawback of incentive compensation; the terms of any Company recoupment, clawback or similar policy in effect at the time of grant of the Award; and any recoupment,
clawback or similar provisions that may be included in the applicable Award Agreement. 
 (d) Fractional Shares. The Company shall
not be required to issue fractional shares upon the exercise or settlement of any Award.
