Vapotherm, Inc. Amended and Restated 2015 Stock Incentive Plan, as amended

Exhibit 10.8

VAPOTHERM, INC.

2015 STOCK INCENTIVE PLAN

Vapotherm, Inc. (the “Company”) hereby establishes this equity-based incentive compensation plan to be known as the “Vapotherm, Inc. 2015 Stock Incentive Plan” (hereinafter referred to as the “Plan”), in order to provide incentives and awards to select key management employees, directors, and advisors of the Company and its Affiliates.

The Plan permits the granting of the following types of awards (“Awards”), according to the Sections of the Plan listed here:

The Plan is not intended to affect and shall not affect any stock options, equity-based compensation, or other benefits that the Company or its Affiliates may have provided, or may separately provide in the future pursuant to any agreement, plan, or program that is independent of this Plan.

Terms in the Plan that begin with an initial capital letter have the defined meaning set forth in Appendix A, unless defined elsewhere in this Plan or the context of their use clearly indicates a different meaning.

Subject to the provisions of Section 13 of the Plan, the maximum number of Shares that the Company may issue for all Awards is 3,424,469 Shares (all of which may be delivered upon the exercise of ISOs), plus any Shares that remain available for grant under the Company’s 2005 Stock Incentive Plan after the date of adoption of the Plan, or that become available for grant under the Company’s 2005 Stock Incentive Plan after the date of adoption of the Plan as a result of forfeiture of awards thereunder. For all Awards, the Shares issued pursuant to the Plan may be authorized but unissued Shares, or Shares that the Company has reacquired or otherwise holds in treasury.

Shares that are subject to an Award that for any reason expires, is forfeited, is cancelled, or becomes unexercisable, and Shares that are for any other reason not paid or delivered under the Plan shall again, except to the extent prohibited by Applicable Law, be available for subsequent Awards under the Plan. In addition, the Committee may make future Awards with respect to Shares that the Company retains from otherwise delivering pursuant to an Award either (i) as payment of the exercise price of an Award, or (ii) in order to satisfy the withholding or employment taxes due upon the grant, exercise, vesting, or distribution of an Award.

(a) General. The Committee shall administer the Plan in accordance with its terms, provided that the Board may act in lieu of the Committee on any matter. The Committee shall hold meetings at such times and places as it may determine and shall make such rules and regulations for the conduct of its business as it deems advisable. In the absence of a duly appointed Committee or if the Board otherwise chooses to act in lieu of the Committee, the Board shall function as the Committee for all purposes of the Plan.

(b) Committee Composition. The Board shall appoint the members of the Committee. If and to the extent permitted by Applicable Law, the Committee may authorize one or more officers to make Awards to Eligible Persons who are not officers. The Board may at any time appoint additional members to the Committee, remove and replace members of the Committee with or without Cause, and fill vacancies on the Committee however caused.

(c) Powers of the Committee. Subject to the provisions of the Plan, the Committee shall have the authority, in its sole discretion:

(i) to determine Eligible Persons to whom Awards shall be granted from time to time and the number of Shares, units, or SARs to be covered by each Award;

(ii) to determine, from time to time, the Fair Market Value of Shares;

(iii) to determine, and to set forth in Award Agreements, the terms and conditions of all Awards, including any applicable exercise or purchase price, the installments and conditions under which an Award shall become vested (which may be based on performance), terminated, expired, cancelled, or replaced, and the circumstances for vesting acceleration or waiver of forfeiture restrictions, and other restrictions and limitations;

(iv) to approve the forms of Award Agreements and all other documents, notices and certificates in connection therewith which need not be identical either as to type of Award or among Participants;

(v) to construe and interpret the terms of the Plan and any Award Agreement, to determine the meaning of their terms, and to prescribe, amend, and rescind rules and procedures relating to the Plan and its administration; and

(vi) in order to fulfill the purposes of the Plan and without amending the Plan, modify, cancel, or waive the Company’s rights with respect to any Awards, to adjust or to modify Award Agreements for changes in Applicable Law or compliance with or exemption from Section 409A of the Code, and to recognize differences in foreign law, tax policies, or customs; and

-2-

(vii) to make all other interpretations and to take all other actions that the Committee may consider necessary or advisable to administer the Plan or to effectuate its purposes.

Subject to Applicable Law and the restrictions set forth in the Plan, the Committee may delegate administrative functions to individuals who are officers or Employees of the Company or its Affiliates.

(d) Deference to Committee Determinations. The Committee shall have the discretion to interpret or construe ambiguous, unclear, or implied (but omitted) terms in any fashion it deems to be appropriate in its sole discretion, and to make any findings of fact needed in the administration of the Plan or Award Agreements. The Committee’s prior exercise of its discretionary authority shall not obligate it to exercise its authority in a like fashion thereafter. The Committee’s interpretation and construction of any provision of the Plan, or of any Award or Award Agreement, shall be final, binding, and conclusive. The validity of any such interpretation, construction, decision or finding of fact shall not be given de novo review if challenged in court, by arbitration, or in any other forum, and shall be upheld unless clearly made in bad faith or materially affected by fraud.

(e) No Liability; Indemnification. Neither the Board nor any Committee member, nor any Person acting at the direction of the Board or the Committee, shall be liable for any act, omission, interpretation, construction or determination made in good faith with respect to the Plan, any Award or any Award Agreement. The Company and its Affiliates shall pay or reimburse any member of the Committee, as well as any Director, Employee, or Consultant who takes action in connection with the Plan, for all expenses incurred with respect to the Plan, and to the full extent allowable under Applicable Law shall indemnify each and every one of them for any claims, liabilities, and costs (including reasonable attorney’s fees) arising out of their good faith performance of duties under the Plan. The Company and its Affiliates may obtain liability insurance for this purpose.

(a) General Rule. The Committee may grant ISOs only to Employees (including officers who are Employees) of the Company or an Affiliate that is a “parent corporation” or “subsidiary corporation” within the meaning of Section 424 of the Code, and may grant all other Awards to any Eligible Person. A Participant who has been granted an Award may be granted an additional Award or Awards if the Committee shall so determine, if such person is otherwise an Eligible Person and if otherwise in accordance with the terms of the Plan.

(b) Grant of Awards. Subject to the express provisions of the Plan, the Committee shall determine from the class of Eligible Persons those individuals to whom Awards under the Plan may be granted, the number of Shares subject to each Award, the price (if any) to be paid for the Shares or the Award and, in the case of Performance Awards, in addition to the matters addressed in Section 10 below, the specific objectives, goals and performance criteria that further define the Performance Award. Each Award shall be evidenced by an Award Agreement signed by the Company and, if required by the Committee, by the Participant. The Award Agreement shall set forth the material terms and conditions of the Award established by the Committee.

-3-

(c) Replacement Awards. Subject to Applicable Laws (including any associated Shareholder approval requirements), the Committee may, in its sole discretion and upon such terms as it deems appropriate, require as a condition of the grant of an Award to a Participant that the Participant surrender for cancellation some or all of the Awards that have previously been granted to the Participant under this Plan or otherwise. An Award that is conditioned upon such surrender may or may not be the same type of Award, may cover the same (or a lesser or greater) number of Shares as such surrendered Award, may have other terms that are determined without regard to the terms or conditions of such surrendered Award, and may contain any other terms that the Committee deems appropriate. In the case of Options, these other terms may not involve an Exercise Price that is lower than the Exercise Price of the surrendered Option unless the Company’s shareholders approve the grant itself or the program under which the grant is made pursuant to the Plan.

(a) Types; Documentation. The Committee may in its discretion grant ISOs to any Employee and Non-ISOs to any Eligible Person, and shall evidence any such grants in an Award Agreement that is delivered to the Participant. Each Option shall be designated in the Award Agreement as an ISO or a Non-ISO, and the same Award Agreement may grant both types of Options. At the sole discretion of the Committee, any Option may be exercisable, in whole or in part, immediately upon the grant thereof, or only after the occurrence of a specified event, or only in installments, which installments may vary. Options granted under the Plan may contain such terms and provisions not inconsistent with the Plan that the Committee shall deem advisable in its sole and absolute discretion.

(b) ISO $100,000 Limitation. To the extent that the aggregate Fair Market Value of Shares with respect to which Options designated as ISOs first become exercisable by a Participant in any calendar year (under this Plan and any other plan of the Company or any Affiliate) exceeds $100,000, such excess Options shall be treated as Non-ISOs. For purposes of determining whether the $100,000 limit is exceeded, the Fair Market Value of the Shares subject to an ISO shall be determined as of the date of grant. In reducing the number of Options treated as ISOs to meet the $100,000 limit, the most recently granted Options shall be reduced first. In the event that Section 422 of the Code is amended to alter the limitation set forth therein, the limitation of this Section 6(b) shall be automatically adjusted accordingly.

(c) Term of Options. Each Award Agreement shall specify a term at the end of which the Option automatically expires, subject to earlier termination provisions contained in Section 6(h) hereof; provided, that, the term of any Option may not exceed ten years from the date of grant. In the case of an ISO granted to an Employee who is a Ten Percent Holder on the date of grant, the term of the ISO shall not exceed five years from the date of grant.

(d) Exercise Price. The exercise price of an Option shall be determined by the Committee in its discretion and shall be set forth in the Award Agreement, subject to the following special rules:

(i) ISOs. If an ISO is granted to an Employee who on the date of grant is a Ten Percent Holder, the per Share exercise price shall not be less than 110% of the Fair Market Value per Share on such date of grant. If an ISO is granted to any other Employee, the per Share exercise price shall not be less than 100% of the Fair Market Value per Share on the date of grant.

-4-

(ii) Non-ISOs. The per Share exercise price for the Shares to be issued pursuant to the exercise of a Non-ISO shall not be less than 50% of the Fair Market Value per Share on the date of grant; provided that the Committee may amend the Plan to increase this percentage at any time.

(e) Exercise of Option. The Committee shall in its sole discretion determine the times, circumstances, and conditions under which an Option shall be exercisable, and shall set them forth in the Award Agreement. The Committee shall have the discretion to determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such leave approved by the Company.

(f) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Committee may require in an Award Agreement that an Option be exercised as to a minimum number of Shares, provided that such requirement shall not prevent a Participant from purchasing the full number of Shares as to which the Option is then exercisable.

(g) Methods of Exercise. Prior to its expiration pursuant to the terms of the applicable Award Agreement, and subject to the times, circumstances and conditions for exercise contained with the applicable Award Agreement, each Option may be exercised, in whole or in part (provided that the Company shall not be required to issue fractional shares), by delivery of written notice of exercise to the secretary of the Company accompanied by the full exercise price of the Shares being purchased. In the case of an ISO, the Committee shall determine the acceptable methods of payment on the date of grant and it shall be included in the applicable Award Agreement. The methods of payment that the Committee may in its discretion accept or commit to accept in an Award Agreement include:

(i) cash or check payable to the Company (in U.S. dollars);

(ii) other Shares that (A) are owned by the Participant who is purchasing Shares pursuant to an Option, (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is being exercised, (C) were not acquired by such Participant pursuant to the exercise of an Option, unless such Shares have been owned by such Participant for at least six months or such other period as the Committee may determine, (D) are all, at the time of such surrender, free and clear of any and all claims, pledges, liens and encumbrances, or any restrictions which would in any manner restrict the transfer of such shares to or by the Company (other than such restrictions as may have existed prior to an issuance of such Shares by the Company to such Participant), and (E) are duly endorsed for transfer to the Company;

(iii) at the election of the Participant, by the Company holding back Shares otherwise deliverable upon exercise having a Fair Market Value equal to the aggregate exercise price of the Shares as to which the Option is being exercised;

-5-

(iv) a cashless exercise program that the Committee may approve, from time to time in its discretion, pursuant to which a Participant may concurrently provide irrevocable instructions (A) to such Participant’s broker or dealer to effect the immediate sale of the purchased Shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the exercise price of the Option plus all applicable taxes required to be withheld by the Company by reason of such exercise, and (B) to the Company to deliver the certificates for the purchased Shares directly to such broker or dealer in order to complete the sale; or

(v) any combination of the foregoing methods of payment.

The Company shall not be required to deliver Shares pursuant to the exercise of an Option until payment of the full exercise price therefore is received by the Company.

(h) Termination of Continuous Service. The Committee may establish and set forth in the applicable Award Agreement the terms and conditions on which an Option shall remain exercisable, if at all, following termination of a Participant’s Continuous Service. The Committee may waive or modify these provisions at any time. To the extent that a Participant is not entitled to exercise an Option at the date of his or her termination of Continuous Service, or if the Participant (or other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified in the Award Agreement or below (as applicable), the Option shall terminate and the Shares underlying the unexercised portion of the Option shall revert to the Plan and become available for future Awards. In no event may any Option be exercised after the expiration of the Option term as set forth in the Award Agreement.

The following provisions shall apply to the extent an Award Agreement does not specify the terms and conditions upon which an Option shall terminate when there is a termination of a Participant’s Continuous Service:

(i) Termination other than Upon Disability or Death or for Cause. In the event of termination of a Participant’s Continuous Service (other than as a result of Participant’s death, disability, Retirement or termination for Cause), the Participant shall have the right to exercise an Option at any time within 90 days following such termination to the extent the Participant was entitled to exercise such Option at the date of such termination.

(ii) Disability. In the event of termination of a Participant’s Continuous Service as a result of his or her being Disabled, the Participant shall have the right to exercise an Option at any time within one year following such termination to the extent the Participant was entitled to exercise such Option at the date of such termination.

(iii) Retirement. In the event of termination of a Participant’s Continuous Service as a result of Participant’s Retirement, the Participant shall have the right to exercise the Option at any time within six months following such termination to the extent the Participant was entitled to exercise such Option at the date of such termination.

-6-

(iv) Death. In the event of the death of a Participant during the period of Continuous Service since the date of grant of an Option, or within thirty days following termination of the Participant’s Continuous Service, the Option may be exercised, at any time within one year following the date of the Participant’s death, by the Participant’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent the right to exercise the Option had vested at the date of death or, if earlier, the date the Participant’s Continuous Service terminated.

(v) Cause. If the Committee determines that a Participant’s Continuous Service terminated due to Cause, the Participant shall immediately forfeit the right to exercise any Option, and it shall be considered immediately null and void.

(i) Reverse Vesting. The Committee in its sole and absolute discretion may allow a Participant to exercise unvested Options, in which case the Shares then issued shall be Restricted Shares having analogous vesting restrictions to the unvested Options.

(j) Adjustment for Section 409A of the Code. In the event an Option is granted with an Exercise Price that is below Fair Market Value on the date of grant, subject to Section 11(e) below, the Option shall be subject to any terms and conditions that the Administrator may in its discretion determine to be necessary to avoid the income tax penalties set forth under Section 409A of the Code.

(a) Grants. The Committee may in its discretion grant Share Appreciation Rights to any Eligible Person, in any of the following forms:

(i) SARs Related to Options. The Committee may grant SARs either concurrently with the grant of an Option or with respect to an outstanding Option, in which case the SAR shall extend to all or a portion of the Shares covered by the related Option. An SAR shall entitle the Participant who holds the related Option, upon exercise of the SAR and surrender of the related Option, or portion thereof, to the extent the SAR and related Option each were previously unexercised, to receive payment of an amount determined pursuant to Section 7(e) below. Any SAR granted in connection with an ISO will contain such terms as may be required to comply with the provisions of Section 422 of the Code and the regulations promulgated thereunder.

(ii) SARs Independent of Options. The Committee may grant SARs which are independent of any Option subject to such conditions as the Committee may in its discretion determine, which conditions will be set forth in the applicable Award Agreement.

(iii) Limited SARs. The Committee may grant SARs exercisable only upon or in respect of a Change in Control or any other specified event, and such limited SARs may relate to or operate in tandem or combination with or substitution for Options or other SARs, or on a stand-alone basis, subject to such conditions as the Committee may in its discretion determine, which conditions will be set forth in the applicable Award Agreement.

(b) Exercise Price. The per Share exercise price of an SAR shall be determined in the sole discretion of the Committee, shall be set forth in the applicable Award Agreement, and shall be no less than the Fair Market Value of one Share. The exercise price of an SAR related to an Option shall be the same as the exercise price of the related Option. The exercise price of an SAR shall be subject to the special rules on pricing contained in Sections 6(d) hereof.

-7-

(c) Exercise of SARs. Unless the Award Agreement otherwise provides, an SAR related to an Option will be exercisable at such time or times, and to the extent, that the related Option will be exercisable. An SAR may not have a term exceeding ten years from its date of grant. An SAR granted independently of any other Award will be exercisable pursuant to the terms of the Award Agreement. Whether an SAR is related to an Option or is granted independently, the SAR may only be exercised when the Fair Market Value of the Shares underlying the SAR exceeds the exercise price of the SAR.

(d) Effect on Available Shares. To the extent that an SAR is exercised, only the actual number of delivered Shares (if any) will be charged against the maximum number of Shares that may be delivered pursuant to Awards under this Plan.

(e) Payment. Upon exercise of an SAR related to an Option and the attendant surrender of an exercisable portion of any related Award, the Participant will be entitled to receive payment of an amount determined by multiplying –

(i) the excess of the Fair Market Value of a Share on the date of exercise of the SAR over the exercise price per Share of the SAR, by

(ii) the number of Shares with respect to which the SAR has been exercised.

Notwithstanding the foregoing, an SAR granted independently of an Option (i) may limit the amount payable to the Participant to a percentage, specified in the Award Agreement but not exceeding one-hundred percent (100%), of the amount determined pursuant to the preceding sentence, and (ii) shall be subject to any payment or other restrictions that the Committee may at any time impose in its discretion, including restrictions intended to conform the SARs with Section 409A of the Code.

(f) Form and Terms of Payment. Subject to Applicable Law, the Committee may, in its sole discretion, settle the amount determined under Section 7(e) above solely in cash, solely in Shares (valued at their Fair Market Value on the date of exercise of the SAR), or partly in cash and partly in Shares. Absent a contrary determination by the Committee, all SARs shall be settled in cash as soon as practicable after exercise. Notwithstanding the foregoing, the Committee may, in an Award Agreement, determine the maximum amount of cash or Shares or combination thereof that may be delivered upon exercise of an SAR.

(g) Termination of Employment or Consulting Relationship. The Committee shall establish and set forth in the applicable Award Agreement the terms and conditions on which an SAR shall remain exercisable, if at all, following termination of a Participant’s Continuous Service. The provisions of Section 6(h) above shall apply to the extent an Award Agreement does not specify the terms and conditions upon which an SAR shall terminate when there is a termination of a Participant’s Continuous Service.

-8-

(a) Grants. The Committee may in its discretion grant restricted shares (“Restricted Shares”) to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant and that sets forth the number of Restricted Shares, the purchase price for such Restricted Shares (if any), and the terms upon which the Restricted Shares may become vested. In addition, the Company may in its discretion grant the right to receive Shares after certain vesting requirements are met (“Restricted Share Units”) to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant which sets forth the number of Shares (or formula, that may be based on future performance or conditions, for determining the number of Shares) that the Participant shall be entitled to receive upon vesting and the terms upon which the Shares subject to a Restricted Share Unit may become vested. The Committee may condition any Award of Restricted Shares or Restricted Share Units to a Participant on receiving from the Participant such further assurances and documents as the Committee may require to enforce the restrictions. In addition, the Committee may grant Awards hereunder in the form of unrestricted shares (“Unrestricted Shares”), which shall vest in full upon the date of grant or such other date as the Committee may determine or which the Committee may issue pursuant to any program under which one or more Eligible Persons (selected by the Committee in its discretion) elect to receive Unrestricted Shares in lieu of cash bonuses that would otherwise be paid.

(b) Vesting and Forfeiture. The Committee shall set forth in an Award Agreement granting Restricted Shares or Restricted Share Units, the terms and conditions under which the Participant’s interest in the Restricted Shares or the Shares subject to Restricted Share Units will become vested and non-forfeitable. Except as set forth in the applicable Award Agreement or the Committee otherwise determines, upon termination of a Participant’s Continuous Service for any other reason, the Participant shall forfeit his or her Restricted Shares and Restricted Share Units; provided that if a Participant purchases the Restricted Shares and forfeits them for any reason, the Company shall return the purchase price to the Participant only if and to the extent set forth in an Award Agreement.

(c) Issuance of Restricted Shares Prior to Vesting. The Company shall issue stock certificates that evidence Restricted Shares pending the lapse of applicable restrictions, and that bear a legend making appropriate reference to such restrictions. Except as set forth in the applicable Award Agreement or the Committee otherwise determines, the Company or a third party that the Company designates shall hold such Restricted Shares and any dividends that accrue with respect to Restricted Shares pursuant to Section 8(e) below.

(d) Issuance of Shares upon Vesting. As soon as practicable after vesting of a Participant’s Restricted Shares (or Shares underlying Restricted Share Units) and the Participant’s satisfaction of applicable tax withholding requirements, the Company shall release to the Participant, free from the vesting restrictions, one Share for each vested Restricted Share (or issue one Share free of the vesting restriction for each vested Restricted Share Unit), unless an Award Agreement provides otherwise. No fractional shares shall be distributed.

(e) Dividends Payable on Vesting. Whenever Shares are released to a Participant or duly-authorized transferee pursuant to Section 8(d) above as a result of the vesting of Restricted Shares or the Shares underlying Restricted Share Units are issued to a Participant pursuant to Section 8(d) above, such Participant or duly-authorized transferee shall also be entitled to receive (unless otherwise provided in the Award Agreement), with respect to each Share released or issued, an amount equal to any cash dividends and a number of Shares equal to any stock dividends, which were declared and paid to the holders of Shares between the date of grant and the date such Share is released from the vesting restrictions in the case of Restricted Shares or issued in the case of Restricted Share Units.

-9-

(f) Section 83(b) Elections. A Participant may make an election under Section 83(b) of the Code (the “Section 83(b) Election”) with respect to Restricted Shares. Shares with respect to which a Participant makes a Section 83(b) Election shall not be eligible for deferral pursuant to Section 9 below.

The Committee may in its discretion grant Deferred Share Units to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant and that sets forth the number of Shares (or formula, that may be based on future performance or conditions, for determining the number of Shares) that the Participant shall be entitled to receive upon settlement, and the terms upon which the Shares subject to a Deferred Share Unit may become vested and settled. The Committee may condition any Award Deferred Share Units to a Participant on receiving from the Participant such further assurances and documents as the Committee may require to enforce the restrictions.

The Committee may in its discretion grant Performance Awards to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant and that sets forth the terms and conditions of the Award. A Performance Award is an Award which is based on the achievement of specific goals with respect to the Company or any Affiliate or individual performance of the Participant, or a combination thereof, over a specified period of time.

(a) General. As a condition to the issuance or distribution of Shares pursuant to the Plan, the Participant (or in the case of the Participant’s death, the person who succeeds to the Participant’s rights) shall make such arrangements as the Company may require for the satisfaction of any applicable federal, state, local or foreign withholding tax obligations that may arise in connection with the Award and the issuance of Shares. The Company shall not be required to issue any Shares until such obligations are satisfied. If the Committee allows the withholding or surrender of Shares to satisfy a Participant’s tax withholding obligations, the Committee shall not allow Shares to be withheld in an amount that exceeds the minimum statutory withholding rates for federal and state tax purposes, including payroll taxes.

(b) Surrender of Shares. If permitted by the Committee, in its discretion, a Participant may satisfy the minimum applicable tax withholding and employment tax obligations associated with an Award by surrendering Shares to the Company (including Shares that would otherwise be issued pursuant to the Award) that have a Fair Market Value determined as of the applicable Tax Date equal to the amount required to be withheld. In the case of Shares previously acquired from the Company that are surrendered under this Section 11, such Shares must have been owned by the Participant for more than six months on the date of surrender (or such longer period of time the Company may in its discretion require).

-10-

(c) Income Taxes and Deferred Compensation. Participants are solely responsible and liable for the satisfaction of all taxes and penalties that may arise in connection with Awards (including any taxes arising under Section 409A of the Code), and the Company shall not have any obligation to indemnify or otherwise hold any Participant harmless from any or all of such taxes. The Administrator shall have the sole discretion to interpret the requirements of the Code, including Section 409A, for purposes of the Plan and all Awards.

(a) General. Except as set forth in this Section 12, or as otherwise approved by the Committee for a select group of management or highly compensated Employees, 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. The designation of a beneficiary by a Participant will not constitute a transfer. An Award may be exercised, during the lifetime of the holder of an Award, only by such holder, the duly-authorized legal representative of a Participant who is Disabled, or a transferee permitted by this Section 12.

(b) Limited Transferability Rights. Notwithstanding anything else in this Section 12, the Committee may in its discretion provide in an Award Agreement that an Award other than an ISO may be transferred, on such terms and conditions as the Committee deems appropriate, either (i) by instrument to the Participant’s “Immediate Family” (as defined below), or (ii) by instrument to an inter vivos or testamentary trust (or other entity) in which the Award is to be passed to the Participant’s designated beneficiaries. “Immediate Family” means any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and shall include adoptive relationships. Any transferee of a Participant’s rights shall succeed to and be subject to all of the terms of the Plan and the Award Agreement (and any amendments thereto) granting the transferred Award.

(a) Changes in Capitalization. The Committee shall equitably adjust the number of Shares covered by each outstanding Award, and the number of Shares that have been authorized for issuance under the Plan but as to which no Awards have yet been granted or that have been returned to the Plan upon cancellation, forfeiture, or expiration of an Award, as well as the price per Share covered by each such outstanding Award, to reflect any increase or decrease in the number of issued Shares resulting from a stock-split, reverse stock-split, stock dividend, combination, recapitalization 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. In the event of any such transaction or event, the Committee may provide in substitution for any or all outstanding Options under the Plan such alternative consideration (including securities of any surviving entity) as it may in good faith determine to be equitable under the circumstances and may require in connection therewith the surrender of all Options so replaced. In any case, such substitution of securities shall not require the consent of any person who is granted Options pursuant to the Plan. Except as expressly provided herein or in an Award Agreement, 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 required to be made with respect to, the number or price of Shares subject to any Award.

-11-

(b) Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company other than as part of a Change in Control, each Award will terminate immediately prior to the consummation of such action, subject to the ability of the Committee to exercise any discretion authorized in the case of a Change in Control.

(c) Change in Control. In the event of a Change in Control, the Committee may in its sole and absolute discretion and authority, without obtaining the approval or consent of the Company’s shareholders or any Participant with respect to his or her outstanding Awards, take one or more of the following actions:

For purposes of this section, “Involuntary Termination” means termination of a Participant’s Continuous Service by the Company without Cause or by reason of the Participant’s resignation within 60 days following (A) a material reduction in the Participant’s job responsibilities, but not a mere change in title; (B) relocation of the Participant’s principal office to a location more than 50 miles from the Participant’s principal office for the Company at the time of the Change in Control; or (C) a reduction in Participant’s then-current total compensation by at least 10%, other than as part of an across-the-board percentage reduction applicable to all other similarly-situated Employees, Directors, or Consultants.

(d) Certain Distributions. In the event of any distribution to the Company’s shareholders of securities of any other entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Committee may, in its discretion, appropriately adjust the price per Share covered by each outstanding Award to reflect the effect of such distribution.

-12-

Within the limitations of the Plan and consistent with the requirements of Section 409A and 424 of the Code, as applicable, the Committee may modify an Award to accelerate the rate at which an Option or SAR may be exercised (including without limitation permitting an Option or SAR to be exercised in full without regard to the installment or vesting provisions of the applicable Award Agreement or whether the Option or SAR is at the time exercisable, to the extent it has not previously been exercised), to accelerate the vesting of any Award, to extend or renew outstanding Awards, or to accept the cancellation of outstanding Awards to the extent not previously exercised either for the granting of new Awards or for other consideration in substitution or replacement thereof. Notwithstanding the foregoing provision, no modification of an outstanding Award shall materially and adversely affect such Participant’s rights thereunder, unless either the Participant provides written consent or there is an express Plan provision permitting the Committee to act unilaterally to make the modification.

The Plan shall continue in effect for a term of ten (10) years from its effective date as determined under Section 19 below or until the tenth anniversary of its approval by the stockholders of the Company, if earlier, unless the Plan is sooner terminated under Section 16 below.

(a) Authority to Amend or Terminate. Subject to Applicable Laws, the Board may from time to time amend, alter, suspend, discontinue, or terminate the Plan.

(b) Effect of Amendment or Termination. No amendment, suspension, or termination of the Plan shall materially and adversely affect Awards already granted unless either it relates to an adjustment pursuant to Section 13 above, or it is otherwise mutually agreed between the Participant and the Committee, which agreement must be in writing and signed by the Participant and the Company. Notwithstanding the foregoing, the Committee may amend the Plan to eliminate provisions which are no longer necessary as a result of changes in tax or securities laws or regulations, or in the interpretation thereof.

Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with Applicable Law, with such compliance determined by the Company in consultation with its legal counsel.

The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

This Plan shall become effective on the date of its approval by the Board; provided that this Plan shall be submitted to the Company’s shareholders for approval, and if not approved by the shareholders in accordance with Applicable Laws (as determined by the Committee in its discretion) within one year from the date of approval by the Board, this Plan and any Awards shall be null, void, and of no force and effect. Awards granted under this Plan before approval of this Plan by the shareholders shall be granted subject to such approval, and no Shares shall be distributed before such approval.

All disputes relating to or arising from the Plan shall be governed by the internal substantive laws (and not the laws of conflicts of laws) of the State of Delaware, to the extent not preempted by United States federal law. If any provision of this Plan is held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions shall continue to be fully effective.

(a) U.S. Securities Laws. This Plan, the grant of Awards, and the exercise of Options and SARs under this Plan, and the obligation of the Company to sell or deliver any of its securities (including, without limitation, Options, Restricted Shares, Restricted Share Units, Deferred Share Units, and Shares) under this Plan shall be subject to all Applicable Law. In the event that the Shares are not registered under the Securities Act of 1933, as amended (the “Act”), or any applicable state securities laws prior to the delivery of such Shares, the Company may require, as a condition to the issuance thereof, that the persons to whom Shares are to be issued represent and warrant in writing to the Company that such Shares are being acquired by him or her for investment for his or her own account and not with a view to, for resale in connection with, or with an intent of participating directly or indirectly in, any distribution of such Shares within the meaning of the Act, and a legend to that effect may be placed on the certificates representing the Shares.

(b) Other Jurisdictions. To facilitate the making of any grant of an Award under this Plan, the Committee may provide for such special terms for Awards to Participants who are foreign nationals or who are employed by the Company or any Affiliate outside of the United States of America as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. The Company may adopt rules and procedures relating to the operation and administration of this Plan to accommodate the specific requirements of local laws and procedures of particular countries. Without limiting the foregoing, the Company is specifically authorized to adopt rules and procedures regarding the conversion of local currency, taxes, withholding procedures and handling of stock certificates which vary with the customs and requirements of particular countries. The Company may adopt sub-plans and establish escrow accounts and trusts as may be appropriate or applicable to particular locations and countries.

Neither a Participant nor any transferee of a Participant shall have any rights as a shareholder of the Company with respect to any Shares underlying any Award until the date of issuance of a share certificate to a Participant or a transferee of a Participant for such Shares in accordance with the Company’s governing instruments and Applicable Law. Prior to the issuance of Shares pursuant to an Award, a Participant shall not have the right to vote or to receive dividends or any other rights as

a shareholder with respect to the Shares underlying the Award, notwithstanding its exercise in the case of Options and SARs. No adjustment will be made for a dividend or other right that is determined based on a record date prior to the date the stock certificate is issued, except as otherwise specifically provided for in this Plan.

The Plan shall not confer upon any Participant any right to continue an employment, service or consulting relationship with the Company, nor shall it affect in any way a Participant’s right or the Company’s right to terminate the Participant’s employment, service, or consulting relationship at any time, with or without Cause.
