Section 2.5 Effective Time and Termination

The Plan originally became effective at the time (the “Effective Time”) it was originally approved by the Board of Zymeworks and has been and may be amended from time to time. No Awards may be issued under the Plan from and after the tenth anniversary of the Effective Time, provided that Awards issued prior to such date shall remain in effect following such date in accordance with their terms.

Section 2.6 Tax Withholdings and Deductions

The Corporation shall have the authority and the right to deduct or withhold from any amount otherwise payable to a Participant, or require a Participant to remit to the Corporation, an amount sufficient for the Corporation to be able to comply with the applicable provisions of any U.S. or non-U.S. federal, provincial, state or local law relating to the withholding of tax or other required deductions (“Tax Obligations”) arising as a result of any Award. Notwithstanding any other provision contained herein, the delivery of Shares with respect to any Award granted under this Plan is subject to the condition that if at any time the Corporation determines, in its discretion, that the satisfaction of the Tax Obligations is necessary or desirable in respect of such delivery, such delivery is not required unless provision for the Tax Obligation has been made to the satisfaction of the Corporation. In such circumstances, the Corporation may require that a Participant pay to the Corporation, in addition to the Exercise Price for the Shares (if applicable), such amount as the Corporation is obliged to remit to the relevant taxing authority in respect of the Award. Any such additional payment is due no later than the date as of which any amount with respect to the Award first becomes includable in the gross income of the Participant for tax purposes. To the extent permitted by the Board, a Participant may direct a portion of the Shares acquired to be sold by a broker to satisfy the Tax Obligations and the funds from such sale to be paid to the Corporation to be remitted to the relevant taxing authority.

Section 2.7 Non-Transferability

Except as set forth herein, Awards are not transferable. Options may be exercised only by:

(a) the Participant to whom the Options were granted;

(b) with the Board’s prior written approval and subject to such conditions as the Corporation may stipulate (which may include conditions with respect to compliance with applicable securities law), such Participant’s family or retirement savings trust or any registered retirement savings plans or registered retirement income funds of which the Participant is and remains the annuitant;

(d) upon the Participant’s Incapacity, the legal representative having authority to deal with the property of the Participant;

provided that any such legal representative shall first deliver evidence satisfactory to the Corporation of entitlement to exercise any Option. A person exercising an Option may subscribe for Shares only in the person’s own name or in the person’s capacity as a legal representative.

Section 2.8 Participation in this Plan

(a) No Participant has any claim or right to be granted an Award (including, without limitation, an Award granted in substitution for any Award that has expired pursuant to the terms of this Plan), and the granting of any Award does not and is not to be construed as giving a Participant a right to continued employment or to remain an employee of the Corporation or an Affiliate of the Corporation. Nothing contained in this Plan or in any Award granted under this Plan shall interfere in any way with the rights of the Corporation or an Affiliate of the Corporation in connection with the employment, retention or termination of any such person.

(b) No Participant has any rights or privileges as a shareholder of the Corporation in respect of Shares with respect to any Award until the allotment and issuance to the Participant of certificates representing such Shares or the entry of such Participant’s name on the share register of the Corporation as the holder of Shares and that person becomes the holder of record of those Shares. The Participant or the Participant’s legal representative shall not, by reason of the grant of any Award (other than an Award of Restricted Stock as set forth in Article 5), be considered to be a shareholder of the Corporation until shares have been issued in respect thereof.

(c) The Corporation makes no representation or warranty as to the future market value of the Shares or with respect to any income tax matters affecting the Participant resulting from the grant, vesting or delivery of an Award or transactions in the Shares. With respect to any fluctuations in the market price of Shares, neither the Corporation, nor any of its directors, officers, employees, shareholders or agents shall be liable for anything done or omitted to be done by such person or any other person with respect to the price, time, quantity or other conditions and circumstances of the issuance of Shares hereunder or in any other manner related to the Plan. For greater certainty, no amount will be paid to, or in respect of, a Participant under the Plan or pursuant to any other arrangement, and no additional Awards will be granted to such Participant to compensate for a downward fluctuation in the price of the Shares, nor will any other form of benefit be conferred upon, or in respect of, a Participant for such purpose. The Corporation does not assume responsibility for the income or other tax consequences resulting to the Participant and they are advised to consult with their own tax advisors.

Section 2.9 Notice

Each notice relating to an Award, including the exercise of an Option, must be in writing. All notices to the Corporation must be delivered personally, by prepaid registered mail or by email and must be addressed to the secretary of the Corporation. All notices to the Participant will be addressed to the principal address of the Participant on file with the Corporation. Either the Corporation or the Participant may designate a different address by written notice to the other. Such notices are deemed to be received: (i) if delivered personally, on the date of delivery; (ii) if sent by prepaid, registered mail, on the fifth Business Day following the date of mailing; or (iii) if sent by email, when the sender receives an email from the recipient acknowledging receipt, provided that an automatic “read receipt” does not constitute acknowledgment of an email for purposes hereof. Any notice given by either the Participant or the Corporation is not binding on the recipient thereof until received.

Section 2.10 Right to Issue Other Shares

The Corporation shall not by virtue of this Plan be in any way restricted from declaring and paying stock dividends, issuing further Shares, repurchasing Shares or varying or amending its share capital or corporate structure.

Section 2.11 Quotation of Shares

So long as the Shares are listed on a Stock Exchange, the Corporation must apply to the Stock Exchange for the listing or quotation, as applicable, of the Shares issued upon the exercise or delivery of all Awards granted under the Plan, however, the Corporation cannot guarantee that such Shares will be listed or quoted on the Stock Exchange or any other stock exchange.

Section 2.12 No Fractional Shares

No fractional Shares shall be issued upon the exercise or delivery of any Award granted under the Plan and, accordingly, if a Participant would become entitled to a fractional Share upon the exercise or delivery of an Award, or from an adjustment permitted by the terms of this Plan, such Participant shall only have the right to purchase or receive the next lowest whole number of Shares, and no payment or other adjustment will be made with respect to the fractional interest so disregarded.

Section 2.13 Governing Law

With respect to Awards granted prior to the Arrangement Effective Time, the Plan shall be governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein. With respect to Awards granted on or after the Arrangement Effective Time, the Plan shall be governed by the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof and the federal laws of the United States applicable therein, without giving effect to the principles of conflicts of law thereof.

ARTICLE IV

EXERCISE & EXPIRY & CHANGE OF CONTROL

Section 4.1 Conditions of Exercise

(a) Vested Options may only be exercised during the Exercise Period by the Participant or upon the Participant’s death or Incapacity, his or her legal representative (provided that such legal representative shall first deliver evidence satisfactory to the Corporation of entitlement to exercise such vested Options). Subject to the restrictions set out in this Plan and to any alternative exercise procedure which may be established from time to time by the Board, Options to acquire Shares may be exercised by delivering to the Corporation an Exercise Notice, together with a bank draft, certified cheque or other form of payment acceptable to the Corporation in an amount equal to the aggregate Exercise Price of the Shares to be purchased pursuant to the exercise of the Options and, if required by Section 2.6, the amount necessary to satisfy any source deductions or withholding taxes.

(b) Pursuant to the Exercise Notice, a Participant may choose to undertake a “cashless exercise” with the assistance of a broker in order to facilitate the exercise of such Participant’s Options. The “cashless exercise” procedure may include a sale of such number of Shares as is necessary to raise an amount equal to the aggregate Exercise Price for all Options being exercised by that Participant under an Exercise Notice. The Participant shall also comply with Section 2.6 of this Plan with regards to any applicable withholding tax and shall comply with all such other procedures and policies as the Corporation may prescribe or determine to be necessary or advisable from time to time in connection with such “cashless exercise.”

(c) In addition, in lieu of exercising any vested Option in the manner described in this Article 4, and pursuant to the terms of this Article 4, a Participant may provide a properly endorsed notice of surrender to the Secretary of the Corporation, substantially in the form of Exhibit “C” to the Grant Agreement (a “Surrender Notice”) pursuant to which the Participant agrees to transfer, dispose and surrender an Option (“Surrender”) to the Corporation and elects to receive that number of Shares calculated using the following formula, after deduction of any income tax and other amounts required by law to be withheld pursuant to Section 2.6:

X = Y * (A-B) / A

Where:

X = the number of Shares to be issued to the Participant

Y = the number of Shares underlying the Options to be Surrendered

A = the Fair Market Value of the Shares as at the date of the Surrender

B = the Exercise Price of such Options

The decision of whether or not to permit Surrender for any Option is at the sole discretion of the Corporation and will be made on a case by case basis.

(d) Where Shares are to be issued to the Participant pursuant to the terms of this Section 4.1, as soon as practicable following the receipt of the Exercise Notice and, if Options are exercised only in accordance with the terms of Section 4.1(a), the required bank draft, certified cheque or other acceptable form of payment, the Corporation shall duly issue such Shares to the Participant as fully paid and non-assessable.

Section 4.2 Exercise Period

(a) The Exercise Period shall be determined by the Board in its sole and absolute discretion at the time the Option is granted and:

(i) each Option shall Expire not later than ten (10) years after the Date of Grant; and

(ii) unless otherwise provided in the Participant’s Grant Agreement, the Exercise Period shall be automatically reduced or the Expiry Date postponed in accordance with this Article 4 upon the occurrence of any of the events referred to herein.

(b) Notwithstanding any other provision of the Plan, if the Expiry Date of an Option falls on a date upon which such Participant is prohibited from exercising such Option due to a blackout period or other trading restriction imposed by the Corporation, then the Expiry Date of such Option shall be automatically extended to the tenth (10th) Business Day following the date

the relevant black-out period or other trading restriction imposed by the Corporation is lifted, terminated or removed; provided, however, that notwithstanding the foregoing, the Expiry Date of an Option shall in no case extend beyond the tenth (10th) anniversary of the date on which it is granted.

Section 4.3 Termination Date

(a) Subject to Section 4.2, unless otherwise provided in the Participant’s Grant Agreement, employment agreement:

(i) if, at any time, a Participant ceases to be an employee of the Corporation or a subsidiary as a result of the Participant’s retirement with the concurrence of the Board, any Options granted to such Participant and vested as of the Termination Date (as defined below) shall remain exercisable by such Participant until the earlier of: (i) 90 days following the Termination Date; and (ii) the Expiry Date. As of the Termination Date, all unvested Options of such Participant shall Expire and such Participant shall no longer be eligible for a grant of Options;

(ii) if, at any time, a Participant ceases to be an employee of the Corporation or a subsidiary as a result of the Participant’s death or Incapacity, any Options granted to such Participant and vested as of the Termination Date shall remain exercisable by such Participant (or, in accordance with Section 2.7, the Participant’s legal representative) until the earlier of: (i) one year following the date of death or the date on which the Board determines that the Incapacity will prevent the employee from fulfilling his or her duties with the Corporation; and (ii) the Expiry Date. As of the Termination Date, all unvested Options of such Participant shall Expire;

(iii) if, at any time, a Participant ceases to be an employee of the Corporation or a subsidiary as a result of the Participant’s termination for cause, as determined by the Board, in its discretion, then, as of the Termination Date, the vested and unvested Options granted to such Participant shall Expire and be of no further force or effect whatsoever and such Participant shall no longer be eligible for a grant of Options;

(iv) if, at any time, a Participant ceases to be an employee of the Corporation or a subsidiary as a result of the Participant’s resignation, then any Options granted to such Participant and vested as of the Termination Date shall remain exercisable by such Participant until the earlier of: (i) 90 days following the Termination Date; and (ii) the Expiry Date. As of the Termination Date, all unvested Options granted to such Participant shall Expire and be of no further force or effect whatsoever and such Participant shall no longer be eligible for a grant of Options; and

(v) if, at any time, a Participant ceases to be an employee of the Corporation or a subsidiary as a result of the Participant’s dismissal without cause, any Options granted to such Participant and vested as of the Termination Date shall remain exercisable by such Participant until the earlier of: (i) ninety (90) days following the Termination Date; and (ii) the Expiry Date. As of the Termination Date, all unvested Options of such Participant shall Expire (for certainty, without regard to any period of reasonable notice that the Corporation or a subsidiary, as the case may be, may be required at law to provide to the Participant) and such Participant shall no longer be eligible for a grant of Options.

(b) Notwithstanding any other provisions of this Section 4.3, the Board may extend the expiration date of vested and unvested Options of a Participant beyond the Expiry Dates set out above, provided that such extended dates are not later than the initial assigned maximum Expiry Date of any such Option.

“Incapacity” means the permanent and total incapacity of a Participant as determined in accordance with procedures established by the Board for purposes of this Plan; and

“Termination Date” means in the case of a Participant whose employment or term of office with the Corporation or a subsidiary terminates in the circumstances set out in Section 4.3, the date that is designated by the Corporation or a subsidiary, as the case may be, as the last day of the Participant’s employment or term of office with the Corporation or a subsidiary, as the case may be, provided that in the case of termination of employment by voluntary resignation by the Participant, such date shall not be earlier than the date notice of resignation was given, and, in the case of a termination by the Corporation without cause, “Termination Date” specifically does not mean the date on which any period of reasonable notice that the Corporation or a subsidiary, as the case may be, may be required at law to provide to the Participant, would expire.

Section 4.4 Change of Control

(a) Notwithstanding anything else in this Plan or any Grant Agreement, the Board has the right to provide for the conversion or exchange of any outstanding Awards into or for options, rights or other securities in any entity participating in or resulting from a Change of Control, cash or other property.

(b) Upon the Corporation entering into an agreement relating to a transaction which, if completed, would result in a Change of Control, or otherwise becoming aware of a pending Change of Control, the Corporation shall give written notice of the proposed Change of Control to the Award holders, together with a description of the effect of such Change of Control on outstanding Awards, not less than seven (7) days prior to the closing of the transaction resulting in the Change of Control.

(c) The Board may, in its sole discretion, accelerate the vesting and/or the Expiry Date of any or all outstanding Awards to provide that, notwithstanding the vesting provisions of such Awards or any Grant Agreement, such designated outstanding Awards shall be fully vested and conditionally exercisable (in the case of Options) upon (or prior to) the completion of the Change of Control provided that the Board shall not, in any case, authorize the exercise of Options pursuant to this Section 4.4(c) beyond the Expiry Date of the Options. If the Board elects to accelerate the vesting and/or the Expiry Date of the Options, then if any of such Options are not

exercised within seven (7) days after the applicable holders are given the notice contemplated in Section 4.4(b) (or such later Expiry Date as the Board may prescribe), such unexercised Options shall, unless the Board otherwise determines, terminate and Expire following the completion of the proposed Change of Control. If, for any reason, the Change of Control does not occur within the contemplated time period, the acceleration of the vesting and the Expiry Date of the Awards shall be retracted and vesting shall instead revert to the manner provided in the Grant Agreement.

(d) To the extent that the Change of Control would also result in a capital reorganization, arrangement, amalgamation or reclassification of the share capital of the Corporation (and the Board does not accelerate the vesting and/or the Expiry Date of Awards pursuant to Section 4.4(c)), the Corporation shall make adequate provisions to ensure that, upon completion of the proposed Change of Control, the number and kind of shares subject to outstanding Awards and, if applicable, the Exercise Price per share of Options shall be appropriately adjusted (including by substituting the Awards for awards with respect to securities in any successor entity to the Corporation) in such manner as the Board considers equitable to prevent substantial dilution or enlargement of the rights granted to Award holders. The Board may make changes to the terms of the Awards or the Plan to the extent necessary or desirable to comply with any rules, regulations or policies of any stock exchange on which any securities of the Corporation may be listed, provided that the value of previously granted Awards and the rights of Award holders are not materially adversely affected by any such changes.

(e) Notwithstanding anything else to the contrary herein, in the event of a potential Change of Control, the Board shall have the power, in its sole discretion, to modify the terms of this Plan and/or the Awards (including, for greater certainty, to cause the vesting of all unvested Awards) to assist the Participants to tender into a take-over bid or other transaction leading to a Change of Control. For greater certainty, in the event of a take-over bid or other transaction leading to a Change of Control, the Board shall have the power, in its sole discretion, to permit Participants to conditionally exercise their Options, such conditional exercise to be conditional upon the take-up by such offeror of the Shares or other securities tendered to such take-over bid in accordance with the terms of such take-over bid (or the effectiveness of such other transaction leading to a Change of Control). If, however, the potential Change of Control referred to in this Section 4.4(e) is not completed within the time specified therein (as the same may be extended), then notwithstanding this Section 4.4(e) or the definition of “Change of Control”: (i) any conditional exercise of vested Options shall be deemed to be null, void and of no effect, and such conditionally exercised Options shall for all purposes be deemed not to have been exercised; (ii) Shares which were issued pursuant to exercise of Options which vested pursuant to this Section 4.4 shall be returned by the Participant to the Corporation and reinstated as authorized but unissued Shares; and (iii) the original terms applicable to Options which vested pursuant to this Section 4.4 shall be reinstated.

ARTICLE V

OTHER AWARDS

Section 5.1 General

In addition to Awards of Options hereunder, the Board may grant the types of Awards described in this Article 5 (“Other Awards”), in accordance with the terms of this Article and the Plan.

The Board has the right to accelerate the date upon which any Other Award vests notwithstanding the vesting schedule set forth for such Other Award, regardless of any adverse or potentially adverse tax consequences resulting from such acceleration.

Section 5.2 Restricted Stock

The Board may grant or award Shares to Eligible Persons that are subject to transfer, vesting and forfeiture restrictions (“Restricted Stock”) in respect of such number of Shares, and subject to such terms or conditions, as it shall determine and specify in a Grant Agreement, and may provide in a Grant Agreement for an Option to be exercisable for Restricted Stock. A holder of Restricted Stock shall have all of the rights of a shareholder of the Corporation, including the right to vote the shares, unless the Board shall otherwise determine at the time of grant; provided that unless the Board determines otherwise any dividends paid on Restricted Stock will be held in escrow until all restrictions on such Shares have lapsed. Unless a Participant’s Grant Agreement provides to the contrary, unvested Restricted Stock shall not be transferred without the written consent of the Board. In addition, at the time of termination for any reason of a Participant’s employment or other service relationship with the Corporation or a subsidiary, unvested Restricted Stock shall be forfeited to the Corporation for no consideration, unless otherwise determined by the Board. Share certificates, if any, representing Awards of Restricted Stock (which may also be held in book entry or similar form) shall be imprinted with a legend to the effect that the Shares represented may not be sold, exchanged, transferred, pledged, hypothecated or otherwise disposed of except in accordance with the terms of the Grant Agreement and, if the Board so determines, the holder may be required to deposit the share certificates or other evidence of legal and beneficial ownership with the President, Chief Financial Officer, Secretary or other officer of the Corporation or with an escrow agent designated by the Board, together with a stock power or other instrument of transfer appropriately endorsed in blank. In the event that the Restricted Stock is not represented by a share certificate, the Corporation shall direct the Corporation’s registrar and transfer agent to make an appropriate notation of the restrictions on transfer to which the Restricted Stock is subject in the stock books and records of the Corporation.

Section 5.3 Restricted Stock Units

The Board may grant Awards payable in Shares upon vesting (“Restricted Stock Units”) to Eligible Persons hereunder, in respect of such number of Shares, and subject to such terms or conditions, as it shall determine and specify in a Grant Agreement. A Restricted Stock Unit represents the right to receive, without payment to the Corporation, a Share. Restricted Stock Units shall become vested as determined by the Board as set forth in the applicable Grant

Agreement, unless otherwise described in the Plan. Amounts payable in connection with a Restricted Stock Unit shall be paid to the holder thereof as set forth in the applicable Grant Agreement, but in no event later than two and one-half months following the end of the calendar year in which the applicable vesting condition is met (unless receipt is deferred in accordance with procedures adopted by the Board, any of which shall comply with the requirements of Section 409A of the Code if the Participant is a United States taxpayer). Restricted Stock Units shall not constitute or be treated as property or as a trust fund of any kind. All amounts at any time attributable to the Restricted Stock Units shall be and remain the sole property of the Corporation and all holders’ rights thereunder are limited to the rights to receive Shares as provided in the Plan and the applicable Grant Agreement.

Section 5.4 Other Share-Based Awards; Performance Vesting

The Board may grant such Other Awards payable in Shares as the Board may determine to be necessary or appropriate, including awards of Shares that are not subject to vesting or forfeiture restrictions. The vesting of Other Awards hereunder may be made subject to the attainment of performance goals, as the Board may determine in its discretion.

This Appendix sets forth special provisions of the Zymeworks Inc. Inducement Stock Option and Equity Compensation Plan (the “Plan”) that apply to U.S. Participants. All Options issued under the Plan to U.S. Participants are intended to be exempt from Section 409A of the Code, or any successor thereto, and all provisions hereunder shall be read, interpreted, and applied with that purpose in mind. Terms used herein that are defined in the Plan shall have the meanings set forth in the Plan, as amended from time to time.

1.	Interpretation

(iii)

“Non-Qualified Option” means any Option granted under the Plan to a U.S. Participant which is not an Incentive Stock Option;

(vi)

“U.S. Participant” shall have the meaning set forth in Section 2(a), below.

(b)

The Plan and this Appendix are complementary to each other and shall, with respect to Options granted to U.S. Participants, be read and deemed as one. In the event of any contradiction, whether explicit or implied, between the provisions of this Appendix and the Plan, the provisions of this Appendix shall prevail with respect to Options granted to U.S. Participants.

(b)

Each U.S. Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or for the account of such U.S. Participant in connection with the Plan (including any taxes and penalties under Section 409A), and neither the Corporation nor any Affiliate of the Corporation shall have any obligation to pay, indemnify or otherwise hold such U.S. Participant (or any beneficiary) harmless from any or all of such taxes or penalties.

(c)

The Corporation and its Affiliates, if applicable, shall withhold taxes according to the requirements of applicable laws, rules and regulations, including the withholding of taxes at source to satisfy any applicable U.S. and non-U.S. federal, provincial, state or local tax withholding obligation and employment taxes.

(d)	Each recipient of an Option hereunder who is or who becomes a U.S. Participant is advised to consult with his or her personal tax advisor with respect to the tax consequences under federal, state, local and other tax laws of the receipt and/or exercise of an Option hereunder.

(e)

Without derogating from the powers and authorities of the Board detailed in the Plan, and unless specifically required under applicable law, the Board shall also have the sole and full discretion and authority to administer the provisions of this Appendix and all actions related thereto including, in addition to any powers and authorities specified in the Plan, the performance, from time to time and at any time, of adopting standard forms of Grant Agreements to be applied with respect to U.S. Participants, incorporating and reflecting, inter alia, relevant provisions regarding the grant of Options in accordance with this Appendix and amending or modifying the terms of such standard forms from time to time.

3.	Exercise Price

The Exercise Price of each Option granted under the Plan to a U.S. Participant shall not be less than the Fair Market Value of a Share on the date such Option is granted. Notwithstanding any other provision of the Plan, in determining the Fair Market Value of a Share under the Plan in connection with the grant of an Option to a U.S. Participant, the Board will make the determination of Fair Market Value in good faith consistent with the rules of Section 409A of the Code and the rules of the Nasdaq, to the extent applicable.

5.	Adjustments to Options

In the event of a corporate transaction requiring the adjustment of an Option held by a U.S. Participant, the number of Shares deliverable on the exercise of an Option held by a U.S. Participant and the Exercise Price of an Option held by a U.S. Participant shall be adjusted in a manner intended to keep the Options exempt from Section 409A of the Code.

6.	Amendment of Appendix

The Board shall retain the power and authority to amend or modify this Appendix and any Option issued hereunder to the extent the Board in its sole discretion deems necessary or advisable to comply with law or regulation, including to comply with any guidance issued under Section 409A of the Code. Such amendments may be made without the approval of any U.S. Participant.

Section 3.1 Participation in the Plan

No Participant has any claim or right to be granted a Restricted Stock Unit, and the granting of any Restricted Stock Unit is not to be construed as giving a Participant a right to continued employment or to remain an employee of the Corporation or an Affiliate of the Corporation.

Section 3.2 Issuance; Binding Agreement

Any issuance of Shares and ownership of the Shares are subject to the terms and conditions of the Plan (all of which are incorporated into and form part of this Grant Agreement) and this Grant Agreement. The Participant’s record of Share ownership shall be recorded in the books of the Corporation only when the Restricted Stock Units vest and the Shares are issued. Shares shall be delivered to the Participant as soon as practicable following the applicable vest date, subject to the Participant’s employment or service on such date. This Grant Agreement shall inure to the benefit of and be binding upon the parties and their respective successors (including any successor by reason of amalgamation of any party) and permitted assigns.

Section 3.3 Miscellaneous

(g)

The Participant hereby acknowledges and agrees that any sums required to satisfy the U.S. and non-U.S. federal, state, provincial and local tax withholding obligations of the Corporation that arise in connection with the Award or the transactions contemplated by this Grant Agreement (the “Tax Obligations”) are the sole responsibility of the Participant. By accepting this Grant Agreement, the Participant hereby agrees that, until and unless the Board determines otherwise, Shares held by the Participant shall be sold on Participant’s behalf in such amounts and at such times as is determined in accordance with this Section 3.3(a), and to allow the Agent (as defined below) to remit the cash proceeds of such sales to the Corporation as more specifically set forth below, as the method by which Participant shall satisfy the Tax Obligations (the “Sell-to-Cover Arrangement”). The Participant further acknowledges and agrees to the following provisions:

(i)

The Participant hereby irrevocably appoints the Corporation’s designated broker Solium Capital Inc., or such other broker as the Corporation may select, as the Participant’s agent (the “Agent”), and authorizes and directs the Agent to implement the Sell-to-Cover Arrangement while in effect, including but not limited to:

Sell on the open market at the then-prevailing market price(s), on the Participant’s behalf, as soon as practicable on or after the delivery of Shares underlying the Restricted Stock Units, the number (rounded up to the next whole number) of Shares sufficient to generate proceeds to cover (A) the satisfaction of the Tax Obligations arising from the settlement of the associated vested Restricted Stock Units and (B) all applicable fees and commissions due to, or required to be collected by, the Agent with respect thereto;

Remit directly to the Corporation the proceeds necessary to satisfy the Tax Obligations arising from the settlement of the associated vested Restricted Stock Units

B-2

Retain the amount required to cover all applicable fees and commissions due to, or required to be collected by, the Agent, relating directly to the sale; and

Deposit any remaining funds in the Participant’s account.

(ii)

The Participant acknowledges that by accepting this Award, he or she is agreeing to the Sell-to-Cover Arrangement as the method through which the Participant shall satisfy the Tax Obligations. The Participant authorizes the Corporation and the Agent to cooperate and communicate with one another to determine the number of Shares that must be sold pursuant to this Section 3.3(a) to satisfy the Tax Obligations.

(iii)

The Participant acknowledges that the Agent is under no obligation to arrange for the sale of Shares at any particular price under the Sell-to-Cover Arrangement and that the Agent may effect sales under the Sell-to-Cover Arrangement in one or more orders and that the average price for executions resulting from bunched orders may be assigned to the Participant’s account. In addition, the Participant acknowledges that it may not always be possible to sell Shares under the Sell-to-Cover Arrangement and in the event of the Agent’s inability to sell Shares, the Participant will continue to be responsible for the Tax Obligations.

(iv)

The Participant hereby agrees to execute and deliver to the Agent any other agreements or documents as the Agent reasonably deems necessary or appropriate to carry out the purposes and intent of the Sell-to-Cover Arrangement. The Agent is a third-party beneficiary of this Section 3.3(a).

(v)

The Participant’s agreement to the Sell-to-Cover Arrangement is irrevocable.

(vi)

The Participant further represents that:

The Participant is agreeing to the Sell-to-Cover Arrangement in good faith and not as part of a plan or scheme to evade any law, including, without limitation, any securities laws; and

The Participant will not disclose to the Agent any information concerning the Corporation that might influence the Agent’s execution of sales under the Sell-to-Cover Arrangement.

(vii)

If the Administrator determines that Participant cannot satisfy Participant’s Tax Obligation through the Sell-to-Cover Arrangement or the Board otherwise determines it is in the best interests of the Corporation for Participant to satisfy Participant’s Tax Obligation by a method other than through the Sell-to-Cover Arrangement, it may permit or require Participant to satisfy Participant’s Tax Obligation, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying cash, (ii) electing to have the Corporation withhold otherwise deliverable Shares having a value equal to the minimum amount statutorily required to be withheld (or such greater amount as Participant may elect

B-3

if permitted by the Board, if such greater amount would not result in adverse financial accounting consequences), (iii) withholding the amount of such Tax Obligation from Participant’s wages or other cash compensation paid to Participant by the Corporation and/or the Affiliate employing or engaging the Participant, (iv) delivering to the Corporation Shares that Participant owns and that have vested with a fair market value equal to the amount required to be withheld (or such greater amount as Participant may elect if permitted by the Board, if such greater amount would not result in adverse financial accounting consequences), or (v) such other means as the Board deems appropriate. To the extent determined appropriate by the Corporation in its discretion, it will have the right (but not the obligation) to satisfy any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant.

(h)

To the extent that the Corporation declares a cash dividend while all or a portion of the Restricted Stock Units are unvested, the Participant shall be credited with dividend equivalent rights (as determined by the Board in its discretion) with respect to each Share subject to the unvested portion of the Restricted Stock Units. Such dividend equivalent right will entitle the Participant to payment of such dividend only upon vesting of the corresponding portion of the Restricted Stock Unit; and such right will be forfeited to the extent the corresponding portion of the Restricted Stock Unit is forfeited.

(i)

No purported sale, assignment, mortgage, hypothecation, transfer, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any of the Restricted Stock Units by any holder thereof shall be valid (other than pursuant to the laws of descent and distribution).
