2005 STOCK INCENTIVE PLAN 

 VAPOTHERM, INC. 

AMENDED AND RESTATED 

2005 STOCK INCENTIVE PLAN 
  

	1.	 Establishment, Purpose, and Types of Awards 

Vapotherm, Inc. (the “Company”) hereby establishes this equity-based incentive compensation plan to be known as the “Vapotherm,
Inc. Amended and Restated 2005 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
terms of this Plan, as amended and restated herein, shall not apply to any Awards granted before January 1, 2005 (except pursuant to the terms and conditions of Section 12 of the Plan, as in effect on December 31, 2004). 

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

 

			
	Section 6	  	Options
	Section 7	  	Share Appreciation Rights
	Section 8	  	Restricted Shares, Restricted Share Units, and Unrestricted Share Awards
	Section 9	  	Deferred Share Units
	Section 10	  	Performance Awards

 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. 

 

	2.	 Defined Terms 

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. 
  

	3.	 Shares Subject to the Plan 

Subject to the provisions of Section 13 of the Plan, the maximum number of Shares that the Company may issue for all Awards is 18,649,180
Shares. 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. Notwithstanding the foregoing, but subject to adjustments pursuant to Section 13 below and to the extent required under applicable tax laws, the number of Shares that are available
for ISO Awards shall equal the number of Shares designated in the preceding paragraph reduced by the number of Shares issued pursuant to Awards, provided that any Shares that are either purchased under the Plan and forfeited back to the Plan or
surrendered in payment of the exercise price for an Award shall be available for issuance pursuant to ISO Awards. 
  

	4.	 Administration 

(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 Reporting Persons (or other officers) to make Awards to Eligible Persons who are not Reporting Persons (or other officers whom the Committee has specifically authorized to make Awards). 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 

  
 -2- 

 (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, and to recognize differences in foreign law, tax policies, or customs; and 

(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 Reporting Persons, 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. 
  

	5.	 Eligibility 

(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) Reserved. 

(d) 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. 

 

	6.	 Option Awards 

(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 Grant Date. 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 Grant Date. In the case of an ISO granted to an Employee who is a Ten
Percent Holder on the Grant Date, the term of the ISO shall not exceed five years from the Grant Date. 

  
 -4- 

 (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 Grant Date 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 Grant Date. 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 Grant Date. 

(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 100% of the Fair Market Value per Share on the Grant Date; 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 Grant Date 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; 

  
 -5- 

 (iii) 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 
 (iv) 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.

 (iv) Death. In the event of the death of a Participant during the period of Continuous Service since the Grant Date
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. 

  
 -6- 

 (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) Buyout
Provisions. The Committee may at any time offer to buy out an Option, in exchange for a payment in cash or Shares, based on such terms and conditions as the Committee shall establish and communicate to the Participant at the time that
such offer is made. In addition, but subject to any Shareholder approval requirement of applicable law, if the Fair Market Value for Shares subject to an Option is more than 33% below their exercise price for more than 30 consecutive business days,
the Committee may unilaterally terminate and cancel the Option either (i) by paying the Participant, in cash or Shares, an amount not less than the Black-Scholes value of the vested portion of the Option, (ii) by irrevocably committing to
grant, on any date the Committee designates, a new Award other an Option or SAR, or (iii) by irrevocably committing to grant a new Option, on a designated date more than six months after such termination and cancellation of such Option (but
only if the Participant’s Continuous Service has not terminated prior to such designated date), on substantially the same terms as the cancelled Option, provided that the per Share exercise price for the new Option shall equal the per Share
Fair Market Value of a Share on the date the new grant occurs. 
 (k) 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 Grant Date, 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. 
  

	7.	 Share Appreciate Rights (SARs) 

(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. 

  
 -7- 

 (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, and may be payable in cash or Shares based on the spread between the exercise price
of the SAR, and (A) a price based upon or equal to the Fair Market Value of the Shares during a specified period, at a specified time within a specified period before, after or including the date of such event, or (B) a price related to
consideration payable to Company’s shareholders generally in connection with the event. 
 (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 100% of 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) and 6(j) hereof. 

(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 Grant Date. 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. The number of Shares subject to the SAR and the related Option of the Participant will, however, be reduced by the number of underlying Shares
as to which the exercise relates, unless the Award Agreement otherwise provides. 
 (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. 

  
 -8- 

 (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. In any
event, cash shall be paid in lieu of fractional 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. 
 (h) Repricing and Buy-out. The Committee has the
same discretion to reprice and to buy-out SARs as it has to take such actions pursuant to Section 6(j) above with respect to Options. 

 

	8.	 Restricted Shares, Restricted Share Units, and Unrestricted Shares 

(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. 

  
 -9- 

 (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, and cash shall be paid in lieu thereof. 

(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 (plus, in the discretion of the Committee, simple interest at a rate as the Committee may
determine) and a number of Shares equal to any stock dividends, which were declared and paid to the holders of Shares between the Grant Date 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. 
 (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. If a Participant who has received Restricted Share Units provides the Committee with written notice of his or her intention to
make a Section 83(b) Election with respect to the Shares subject to such Restricted Share Units, the Committee may in its discretion convert the Participant’s Restricted Share Units into Restricted Shares, on a one-for-one basis, in full satisfaction of the Participant’s Restricted Share Unit Award. The Participant may then make a Section 83(b) Election with respect to
those 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. 

(g) Deferral Elections. At any time within the thirty-day period (or other shorter or longer
period that the Committee selects) in which a Participant who is a member of a select group of management or highly compensated employees (within the meaning of the Code) receives an Award of either Restricted Shares or Restricted Share Units,
the Committee may permit the Participant to irrevocably elect, on a form provided by and acceptable to the Committee, to defer the receipt of all or a percentage of the Shares that would otherwise be transferred to the Participant upon the vesting
of such Award. If the Participant makes this election, the Shares subject to the election, and any associated dividends and interest, shall be credited to an account established pursuant to Section 9 hereof on the date such Shares would
otherwise have been released or issued to the Participant pursuant to Section 8(d) above. 

  
 -10- 

	9.	 Deferred Share Units 

(a) Elections to Defer. The Committee may permit any Eligible Person who is a Director, Consultant or member of a select group of
management or highly compensated employees (within the meaning of the Code) to irrevocably elect, on a form provided by and acceptable to the Committee (the “Election Form”), to forego the receipt of cash or other compensation (including
the Shares deliverable pursuant to any Award other than Restricted Shares for which a Section 83(b) Election has been made), and in lieu thereof to have the Company credit to an internal Plan account (the “Account”) a number of
deferred share units (“Deferred Share Units”) having a Fair Market Value equal to the Shares and other compensation deferred. These credits will be made at the end of each calendar quarter (or other period that the Administrator
establishes prospectively) during which compensation is deferred. Unless, within five business days after the Company receives an election form, the Company sends the Participant a written notice explaining why it is invalid, each Election Form
shall take effect on the first day of the next calendar year (or on the first day of the next calendar month in the case of an initial election by a Participant who is first eligible to defer hereunder) after its delivery to the Company, subject to
Section 8(g) regarding deferral of Restricted Shares and Restricted Share Units and to Section 10(e) regarding deferral of Performance Awards. Notwithstanding the foregoing sentence: (i) Election Forms shall be ineffective with
respect to any compensation that a Participant earns before the date on which the Company receives the Election Form, and (ii) the Committee may unilaterally make awards in the form of Deferred Share Units, regardless of whether or not the
Participant foregoes other compensation. 
 (b) Vesting. Unless an Award Agreement expressly provides otherwise, each Participant
shall be 100% vested at all times in any Shares subject to Deferred Share Units. 
 (c) Issuances of Shares. The Company shall
provide a Participant with one Share for each Deferred Share Unit in five substantially equal annual installments that are issued before the last day of each of the five calendar years that end after the date on which the Participant’s
Continuous Service terminates, unless – 
 (i) the Participant has properly elected a different form of
distribution, on a form approved by the Committee, that permits the Participant to select any combination of a lump sum and annual installments that are completed within ten years following termination of the Participant’s Continuous Service,
and 
 (ii) the Company received the Participant’s distribution election form at the time the Participant elects to
defer the receipt of cash or other compensation pursuant to Section 9(a), provided that (subject to any prospective changes that the Administrator communicates in writing to a Participant), the Participant may change such election through any
subsequent election that (i) is delivered to the Administrator at least one year before the date on which distributions are otherwise scheduled to commence pursuant to the Participant’s election, and (ii) defers the commencement of
distributions by at least five years from the originally scheduled commencement date. 
 Fractional shares shall not be issued, and instead
shall be paid out in cash. 

  
 -11- 

 (d) Crediting of Dividends. Whenever Shares are issued to a Participant pursuant to
Section 9(c) above, such Participant shall also be entitled to receive, with respect to each Share issued, a cash amount equal to any cash dividends (plus simple interest at a rate of five percent per annum, or such other reasonable rate
as the Committee may determine in an Award Agreement), and a number of Shares equal to any stock dividends which were declared and paid to the holders of Shares between the Grant Date and the date such Share is issued. 

(e) Emergency Withdrawals. In the event a Participant suffers an unforeseeable emergency within the contemplation of this Section
and Section 409A of the Code, the Participant may apply to the Company for an immediate distribution of all or a portion of the Participant’s Deferred Share Units. The unforeseeable emergency must result from a sudden and unexpected
illness or accident of the Participant, the Participant’s spouse, or a dependent (within the meaning of Section 152(a) of the Code) of the Participant, casualty loss of the Participant’s property, or other similar extraordinary and
unforeseeable conditions beyond the control of the Participant. Examples of purposes which are not considered unforeseeable emergencies include post-secondary school expenses or the desire to purchase a residence. In no event will a distribution be
made to the extent the unforeseeable emergency could be relieved through reimbursement or compensation by insurance or otherwise, or by liquidation of the Participant’s nonessential assets to the extent such liquidation would not itself cause a
severe financial hardship. The amount of any distribution hereunder shall be limited to the amount necessary to relieve the Participant’s unforeseeable emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the
distribution. The Committee shall determine whether a Participant has a qualifying unforeseeable emergency and the amount which qualifies for distribution, if any. The Committee may require evidence of the purpose and amount of the need, and may
establish such application or other procedures as it deems appropriate. 
 (f) Unsecured Rights to Deferred Compensation. A
Participant’s right to Deferred Share Units shall at all times constitute an unsecured promise of the Company to pay benefits as they come due. The right of the Participant or the Participant’s duly-authorized transferee to receive
benefits hereunder shall be solely an unsecured claim against the general assets of the Company. Neither the Participant nor the Participant’s duly-authorized transferee shall have any claim against or rights in any specific assets, shares, or
other funds of the Company. 
  

	10.	 Performance Awards 

(a) Performance Units. Subject to the limitations set forth in paragraph (c) hereof, the Committee may in its discretion
grant Performance Units to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant which sets forth the terms and conditions of the Award. A Performance Unit 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. 

(b) Performance Compensation Awards. Subject to the limitations set forth in paragraph (c) hereof, the Committee may, at the
time of grant of a Performance Unit, designate such Award as a “Performance Compensation Award” in order that such Award constitutes “qualified performance-based compensation” under Code Section 162(m), in which event the
Committee shall have the power to grant such Performance Compensation Award upon terms and conditions that qualify it as “qualified performance-based compensation” within the meaning of Code Section 162(m). With respect to each such
Performance Compensation Award, the Committee shall establish, in writing within the time required under Code Section 162(m), a “Performance Period,” “Performance Measure(s)”, and “Performance Formula(e)” (each
such term being hereinafter defined). Once 

	
	

  
 -12- 

 established for a Performance Period, the Performance Measure(s) and Performance Formula(e) shall not be
amended or otherwise modified to the extent such amendment or modification would cause the compensation payable pursuant to the Award to fail to constitute qualified performance-based compensation under Code Section 162(m). 

A Participant shall be eligible to receive payment in respect of a Performance Compensation Award only to the extent that the Performance
Measure(s) for such Award is achieved and the Performance Formula(e) as applied against such Performance Measure(s) determines that all or some portion of such Participant’s Award has been earned for the Performance Period. As soon as
practicable after the close of each Performance Period, the Committee shall review and certify in writing whether, and to what extent, the Performance Measure(s) for the Performance Period have been achieved and, if so, determine and certify in
writing the amount of the Performance Compensation Award to be paid to the Participant and, in so doing, may use negative discretion to decrease, but not increase, the amount of the Award otherwise payable to the Participant based upon such
performance. 
 (c) Limitations on Awards. The maximum Performance Unit Award and the maximum Performance Compensation Award
that any one Participant may receive for any one Performance Period shall not together exceed 50,000 Shares and $250,000 in cash. The Committee shall have the discretion to provide in any Award Agreement that any amounts earned in excess of these
limitations will either be credited as Deferred Share Units, or as deferred cash compensation under a separate plan of the Company (provided in the latter case that such deferred compensation either bears a reasonable rate of interest or has a value
based on one or more predetermined actual investments). Any amounts for which payment to the Participant is deferred pursuant to the preceding sentence shall be paid to the Participant in a future year or years not earlier than, and only to the
extent that, the Participant is either not receiving compensation in excess of these limits for a Performance Period, or is not subject to the restrictions set forth under Section 162(m) of the Code. 

(d) Definitions. 

(i) “Performance Formula” means, for a Performance Period, one or more objective formulas or standards established by
the Committee for purposes of determining whether or the extent to which an Award has been earned based on the level of performance attained or to be attained with respect to one or more Performance Measure(s). Performance Formulae may vary from
Performance Period to Performance Period and from Participant to Participant and may be established on a stand-alone basis, in tandem or in the alternative. 

(ii) “Performance Measure” means one or more of the following selected by the Committee to measure Company,
Affiliate, and/or business unit performance for a Performance Period, whether in absolute or relative terms (including, without limitation, terms relative to a peer group or index): basic, diluted, or adjusted earnings per share; sales or revenue;
earnings before interest, taxes, and other adjustments (in total or on a per share basis); basic or adjusted net income; returns on equity, assets, capital, revenue or similar measure; economic value added; working capital; total shareholder return;
and product development, product market share, research, licensing, litigation, human resources, information services, mergers, acquisitions, sales of assets of Affiliates or business units. Each such measure shall be, to the extent applicable,
determined in accordance with 

  
 -13- 

 generally accepted accounting principles as consistently applied by the Company (or such
other standard applied by the Committee) and, if so determined by the Committee, and in the case of a Performance Compensation Award, to the extent permitted under Code Section 162(m), adjusted to omit the effects of extraordinary items, gain
or loss on the disposal of a business segment, unusual or infrequently occurring events and transactions and cumulative effects of changes in accounting principles. Performance Measures may vary from Performance Period to Performance Period and from
Participant to Participant, and may be established on a stand-alone basis, in tandem or in the alternative. 
 (iii)
“Performance Period” means one or more periods of time (of not less than one fiscal year of the Company), as the Committee may designate, over which the attainment of one or more Performance Measure(s) will be measured for the purpose of
determining a Participant’s rights in respect of an Award. 
 (e) Deferral Elections. At any time prior to the date that is at
least six months before the close of a Performance Period (or shorter or longer period that the Committee selects) with respect to an Award of either Performance Units or Performance Compensation, the Committee may permit a Participant who is
a member of a select group of management or highly compensated employees (within the meaning of the Code) to irrevocably elect, on a form provided by and acceptable to the Committee, to defer the receipt of all or a percentage of the cash or Shares
that would otherwise be transferred to the Participant upon the vesting of such Award. If the Participant makes this election, the cash or Shares subject to the election, and any associated interest and dividends, shall be credited to an account
established pursuant to Section 9 hereof on the date such cash or Shares would otherwise have been released or issued to the Participant pursuant to Section 10(a) or Section 10(b) above. 

 

	11.	 Taxes 

(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) Default Rule for Employees. In the absence of any other arrangement, an Employee shall be deemed to have directed the Company
to withhold or collect from his or her cash compensation an amount sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of the exercise of an Award. 

(c) Special Rules. In the case of a Participant other than an Employee (or in the case of an Employee where the next payroll
payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the absence of any other arrangement and to the extent permitted under Applicable Law, the Participant shall be deemed to have elected to
have the Company withhold from the Shares or cash to be issued pursuant to an Award that number of 

  
 -14- 

 Shares having a Fair Market Value determined as of the applicable Tax Date (as defined below) or cash equal
to the amount required to be withheld. For purposes of this Section 11, the Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined under the Applicable Law (the
“Tax Date”). 
 (d) 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). 
 (e) 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 discretion to organize any deferral program, to require deferral election forms, and to
grant or to unilaterally modify any Award in a manner that (i) conforms with the requirements of Section 409A of the Code with respect to compensation that is deferred and that vests after December 31, 2004, (ii) voids any Participant
election to the extent it would violate Section 409A of the Code, and (iii) for any distribution event or election that could be expected to violate Section 409A of the Code, make the distribution only upon the earliest of the first
to occur of a “permissible distribution event” within the meaning of Section 409A of the Code, or a distribution event that the Participant elects in accordance with Section 409A of the Code. 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. 
  

	12.	 Non-Transferability of 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), (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, or (iii) by gift to charitable institutions.
“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. 

  
 -15- 

	13.	 Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions

 (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. 
 (b) Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company other than as part of a
Change of 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: 

 

	 	(i)	 arrange for or otherwise provide that each outstanding Award shall be assumed or a substantially similar award
shall be substituted by a successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”) in which case a Participant who is Involuntarily Terminated (as defined below) in connection with, or
within 12 months following the Change in Control shall become fully vested in any assumed or substituted Award held by the terminated Participant at the time of termination; 

 

	 	(ii)	 terminate upon the consummation of the transaction, provided that the vesting of all outstanding Awards shall
accelerate in full as of a date immediately prior to consummation of the Change of Control. To the extent that an Award is not exercised prior to consummation of a transaction in which the Award is not being assumed or substituted, such Award shall
terminate upon such consummation; or 

  

	 	(iii)	 be assumed, or an equivalent award shall be substituted, by any Successor Company. 

  
 -16- 

 For purposes of this section, “Involuntary Termination” means termination
of a Participant’s Continuous Service without Cause ; or by 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 of 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. 
  

	14.	 Time of Granting Awards. 

The date of grant (“Grant Date”) of an Award shall be the date on which the Committee makes the determination granting such Award or
such other date as is determined by the Committee, provided that in the case of an ISO, the Grant Date shall be the later of the date on which the Committee makes the determination granting such ISO or the date of commencement of the
Participant’s employment relationship with the Company. 
  

	15.	 Modification of Awards and Substitution of Options. 

(a) Modification, Extension, and Renewal of Awards. Within the limitations of the Plan, 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. 

(b) Substitution of Options. Notwithstanding any inconsistent provisions or limits under the Plan, in the event the Company or an
Affiliate acquires (whether by purchase, merger or otherwise) all or substantially all of outstanding capital stock or assets of another corporation or in the event of any reorganization or other transaction qualifying under Section 424 of the
Code, the Committee may, in accordance with the provisions of that Section, substitute Options for options under the plan of the acquired company provided (i) the excess of the aggregate fair market value of the shares subject to an option
immediately after the substitution over the aggregate option price of such shares is not more than the similar excess immediately before such substitution and (ii) the new option does not give persons additional benefits, including any
extension of the exercise period. 

  
 -17- 

	16.	 Term of Plan. 

The Plan shall continue in effect for a term of ten (10) years from its effective date as determined under Section 20 below, unless
the Plan is sooner terminated under Section 17 below. 
  

	17.	 Amendment and Termination of the Plan. 

(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. 
  

	18.	 Conditions Upon Issuance of Shares. 

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. 
  

	19.	 Reservation of Shares. 

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. 
  

	20.	 Effective Date. 

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. 

 

	21.	 Controlling Law. 

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 Maryland, 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. 

  
 -18- 

	22.	 Laws And Regulations. 

(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. 

23. No Shareholder Rights. 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. 

24. No Employment Rights. 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.

“Affiliate” means, with respect to any Person (as defined below), any other Person that directly
or indirectly controls or is controlled by or under common control with such Person. For the purposes of this definition, “control,” when used with respect to any Person, means the possession, direct or indirect, of the power to direct or
cause the direction of the management and policies of such Person or the power to elect directors, whether through the ownership of voting securities, by contract or otherwise; and the terms “affiliated,” “controlling” and
“controlled” have meanings correlative to the foregoing. 
 “Applicable Law” means the legal
requirements relating to the administration of options and share-based plans under applicable U.S. federal and state laws, the Code, any applicable stock exchange or automated quotation system rules or regulations, and the applicable laws of
any other country or jurisdiction where Awards are granted, as such laws, rules, regulations and requirements shall be in place from time to time. 

“Award” means any award made pursuant to the Plan, including awards made in the form of an
Option, an SAR, a Restricted Share, a Restricted Share Unit, an Unrestricted Share, a Deferred Share Unit and a Performance Award, or any combination thereof, whether alternative or cumulative, authorized by and granted under this Plan. 

“Award Agreement” means any written document setting forth the terms of an Award that has been
authorized by the Committee. The Committee shall determine the form or forms of documents to be used, and may change them from time to time for any reason. 

“Board” means the Board of Directors of the Company. 

“Cause” for termination of a Participant’s Continuous Service will exist if the Participant is
terminated from employment or other service with the Company or an Affiliate for any of the following reasons: (i) the Participant’s willful failure to substantially perform his or her duties and responsibilities to the Company or
deliberate violation of a material Company policy; (ii) the Participant’s commission of any material act or acts of fraud, embezzlement, dishonesty, or other willful misconduct; (iii) the Participant’s material unauthorized use
or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or her relationship with the Company; or (iv) Participant’s
willful and material breach of any of his or her obligations under any written agreement or covenant with the Company. 

 The Committee shall in its discretion determine whether or not a Participant is being
terminated for Cause. The Committee’s determination shall, unless arbitrary and capricious, be final and binding on the Participant, the Company, and all other affected persons. The foregoing definition does not in any way limit the
Company’s ability to terminate a Participant’s employment or consulting relationship at any time, and the term “Company” will be interpreted herein to include any Affiliate or successor thereto, if appropriate. 

“Change in Control” means the first of the following to occur after the date of adoption of this
Plan (as set forth in Section 4.5.1 hereto), excluding any event that is Management Action: 
 (i) Acquisition of
Controlling Interest. Any Person (other than Persons who are Employees at any time more than one year before a transaction) becomes the Beneficial Owner, directly or indirectly, of
securities of the Company representing 50% or more of the combined voting power of the Company’s then outstanding securities. In applying the preceding sentence, (i) securities acquired directly from the Company or its
Affiliates by or for the Person shall not be taken into account, and (ii) an agreement to vote securities shall be disregarded unless its ultimate purpose is to cause what would otherwise be Change of Control, as reasonably determined by the

commencing after the date of adoption of this Plan, individuals who constituted the Board at the beginning of the period (or their approved replacements, as defined in the next sentence) cease for any reason to constitute a majority of the
Board. A new Director shall be considered an “approved replacement” Director if his or her election (or nomination for election) was approved by a vote of at least a majority of the Directors then still in office who either were Directors
at the beginning of the period or were themselves approved replacement Directors, but in either case excluding any Director whose initial assumption of office occurred as a result of an actual or threatened solicitation of proxies or consents by or
on behalf of any Person other than the Board. 
 (iii) Merger Approved. The Company consummates a merger, or
consolidation of the Company with any other corporation unless: (a) the voting securities of the Company outstanding immediately before the merger or consolidation would continue to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; and
(b) no Person (other than Persons who are Employees at any time more than one year before a transaction) becomes the Beneficial Owner, directly or indirectly, of securities of the Company representing
50% or more of the combined voting power of the Company’s then outstanding securities. 
 (iv) Sale of
Assets. The stockholders of the Company approve an agreement for the sale or disposition by the Company of all, or substantially all, of the Company’s assets. 

(v) Liquidation or Dissolution. The stockholders of the Company approve a plan or proposal for liquidation or
dissolution of the Company. 

  
 -2- 

 Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have
occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the record holders of the common stock of the Company immediately prior to such transaction or series of transactions continue
to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions. 

“Code” means the U.S. Internal Revenue Code of 1986, as amended. 

“Committee” means one or more committees or subcommittees of the Board appointed by the Board to
administer the Plan in accordance with Section 4 above. With respect to any decision involving an Award intended to satisfy the requirements of Section 162(m) of the Code, the Committee shall consist of two or more Directors of the Company
who are “outside directors” within the meaning of Section 162(m) of the Code. With respect to any decision relating to a Reporting Person, the Committee shall consist of two or more Directors who are disinterested within the meaning
of Rule 16b-3.

Affiliate to render services and is compensated for such services. 
 “Continuous Service” means the
absence of any interruption or termination of service as an Employee, Director, or Consultant. Continuous Service shall not be considered interrupted in the case of: (i) sick leave; (ii) military leave; (iii) any other leave of
absence approved by the Committee, provided that such leave is for a period of not more than 90 days, unless reemployment upon the expiration of such leave is guaranteed by contract or statute, or unless provided otherwise pursuant to Company policy
adopted from time to time; (iv) changes in status from Director to advisory director or emeritus status; or (iv) in the case of transfers between locations of the Company or between the Company, its Affiliates or their respective
successors. Changes in status between service as an Employee, Director, and a Consultant will not constitute an interruption of Continuous Service. 

“Deferred Share Units” mean Awards pursuant to Section 9 of the Plan. 

“Director” means a member of the Board, or a member of the board of directors of an Affiliate.

 “Disabled” means a condition under which a Participant — 

(a) is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be

Company. 
 “Eligible Person” means any Consultant, Director or Employee and includes non-Employees to whom an offer of employment has been extended. 

“Employee” means any person whom the Company or any Affiliate classifies as an employee

Company or any Committee appointed by the Board to administer the Plan, and shall (in the absence of decisions clearly made in bad faith or materially effected by fraud) be final, conclusive and binding on all parties, including you and your
successors in interest. Capitalized terms are defined in the Plan or in this Award Agreement. 
 1.    Variable
Terms. This Option shall have, and be interpreted according to, the following terms, subject to the provisions of the Plan in all instances:

		  	☐  Not allowed.

  

	1 	 If an ISO is awarded to a person owning more than 10% of the voting power of all classes of stock of the

	Expiration Date:	  	☐	  	         years after Grant Date
		  	☐	  	10 years after Grant Date

 2.    Accelerated Vesting; Change in Corporate Control. To the extent you have
not previously vested in your rights with respect to this Award, your Award will become fully vested on the earlier to occur of (a) the one-year anniversary of a Change in Control or (b) if your
Continuous Service ends due to a termination by you for Good Reason or by the Company without Cause, in each case within 12 months following a Change in Control. 

3.    Term of Option. The term of the Option will expire at 5:00 p.m. (E.D.T. or E.S.T., as applicable) on the
Expiration Date. 
 4.    Manner of Exercise. The Option shall be exercised in the manner set forth in the
Plan, using the exercise form attached hereto as Exhibit B. The amount of Shares for which the Option may be exercised is cumulative; that is, if you fail to exercise the Option for all of the Shares vested under the Option during any period
set forth above, then any Shares subject to the Option that are not exercised during such period may be exercised during any subsequent period, until the expiration or termination of the Option pursuant to Sections 2 and 6 of this Award Agreement
and the terms of the Plan. Fractional Shares may not be purchased. 
 5.    Special ISO Provisions. If
designated as an ISO, this Option shall be treated as an ISO to the extent allowable under Section 422 of the Code, and shall otherwise be treated as a NQSO. If you sell or otherwise dispose of Shares acquired upon the exercise of an ISO within
1 year from the date such Shares were acquired or 2 years from the Grant Date, you agree to deliver a written report to the Company within 10 days following the sale or other disposition of such Shares detailing the net proceeds of such sale or

Company, but subject to the terms of the Participant’s Employment Agreement, the Participant shall devote his or her full energies, abilities, attention and business time to the performance of his or her job responsibilities and shall not
engage in any activity which conflicts or interferes with, or in any way compromises, his or her performance of such responsibilities. 

  
 -2- 

 (b)    Confidential Information. The Participant recognizes that
by virtue of his or her employment with the Company, he or she will be granted otherwise prohibited access to confidential information and proprietary data which are not known, and not readily accessible to the Company’s competitors. This
information (the “Confidential Information”) includes, but is not limited to, current and prospective customers; the identity of key contacts at such customers; customers’ particularized preferences and needs; marketing strategies and
plans; financial data; personnel data; compensation data; proprietary procedures and processes; and other unique and specialized practices, programs and plans of the Company and its customers and prospective customers. The Participant recognizes
that this Confidential Information constitutes a valuable property of the Company, developed over a significant period of time and at substantial expense. Accordingly, the Participant agrees that he or she shall not, at any time during or after his
or her employment with the Company, divulge such Confidential Information or make use of it for his or her own purposes or the purposes of any person or entity other than the Company. 

(c)    Non-Solicitation of Customers. The Participant recognizes that by
virtue of his or her employment with the Company he or she will be introduced to and involved in the solicitation and servicing of existing customers of the Company and new customers obtained by the Company during his or her employment. The
Participant understands and agrees that all efforts expended in soliciting and servicing such customers shall be for the permanent benefit of the Company. The Participant further agrees that during his or her employment with the Company the
Participant will not engage in any conduct which could in any way jeopardize or disturb any of the Company’s customer relationships. The Participant also recognizes the Company’s legitimate interest in protecting, for a reasonable period
of time after his or her employment with the Company, the Company’s customers. Accordingly, the Participant agrees that, for a period beginning on the date hereof and ending one (1) year after termination of Participant’s employment
with the Company, regardless of the reason for such termination, the Participant shall not, directly or indirectly, without the prior written consent of the Chairman of the Company, market, offer, sell or otherwise furnish any products or services
similar to, or otherwise competitive with, those offered by the Company to any customer of the Company. 
 (d)    Non-Solicitation of Employees. The Participant recognizes the substantial expenditure of time and effort which the Company devotes to the recruitment, hiring, orientation, training and retention of its
employees. Accordingly, the Participant agrees that, for a period beginning on the date hereof and ending eighteen (18) months after termination of Participant’s employment with the Company, regardless of the reason for such termination,
the Participant shall not, directly or indirectly, for himself or herself or on behalf of any other person or entity, solicit, recruit, or induce the termination of employment of any employee of the Company. 

(e)    Survival of Commitments; Potential Recapture of Award and Proceeds. The Participant acknowledges and agrees
that the terms and conditions of this Section regarding confidentiality and non-solicitation shall survive both (i) the termination of Participant’s employment with the Company for any reason, and
(ii) the termination of the Plan, for any reason. The Participant acknowledges and agrees that the grant of Options in this Award Agreement is just and adequate consideration for the survival of the restrictions set forth herein,

  
 -3- 

 
and that the Company may pursue any or all of the following remedies if the Participant either violates the terms of this Section or succeeds for any reason in invalidating any part of it (it
being understood that the invalidity of any term hereof would result in a failure of consideration for the Award): 
  

	 	(i)	 declaration that the Award is null and void and of no further force or effect; 

 

	 	(ii)	 recapture of any cash paid or Shares issued to the Participant, or any designee or beneficiary of the
Participant, pursuant to the Award; 

  

	 	(iii)	 recapture of the proceeds, plus reasonable interest, with respect to any Shares that are both issued pursuant
to this Award and sold or otherwise disposed of by the Participant, or any designee or beneficiary of the Participant. 

 The remedies
provided above are not intended to be exclusive, and the Company may seek such other remedies as are provided by law, including equitable relief. 

(f)    Acknowledgement. The Participant acknowledges and agrees that his or her adherence to the foregoing
requirements will not prevent him or her from engaging in his or her chosen occupation and earning a satisfactory livelihood following the termination of his or her employment with the Company. 

8.    Designation of Beneficiary. Notwithstanding anything to the contrary contained herein or in the Plan, following
the execution of this Award Agreement, you may expressly designate a beneficiary (the “Beneficiary”) to his or her interest in the Option awarded hereby. You shall designate the Beneficiary by completing and executing a designation

prior written consent of the Committee. Notwithstanding the foregoing, the Participant may transfer this Option (i) by instrument to an inter vivos or testamentary trust (or other entity) in which each beneficiary is a permissible gift
recipient, as such is set forth in subsection (ii) of this Section, or (ii) by gift to charitable institutions or by gift or transfer not for consideration to any of the following relatives of the Participant (or to an inter vivos trust,

Vapotherm, Inc. (the “Company”) hereby establishes this equity-based incentive compensation plan to be known as the “Vapotherm,
Inc. Amended and Restated 2005 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
terms of this Plan, as amended and restated herein, shall not apply to any Awards granted before January 1, 2005 (except pursuant to the terms and conditions of Section 12 of the Plan, as in effect on December 31, 2004). 

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

 

			
	Section 6	  	Options
	Section 7	  	Share Appreciation Rights
	Section 8	  	Restricted Shares, Restricted Share Units, and Unrestricted Share Awards
	Section 9	  	Deferred Share Units
	Section 10	  	Performance Awards

 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. 

 

	2.	 Defined Terms 

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. 
  

	3.	 Shares Subject to the Plan 

Subject to the provisions of Section 13 of the Plan, the maximum number of Shares that the Company may issue for all Awards is 18,649,180
Shares. 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. Notwithstanding the foregoing, but subject to adjustments pursuant to Section 13 below and to the extent required under applicable tax laws, the number of Shares that are available
for ISO Awards shall equal the number of Shares designated in the preceding paragraph reduced by the number of Shares issued pursuant to Awards, provided that any Shares that are either purchased under the Plan and forfeited back to the Plan or
surrendered in payment of the exercise price for an Award shall be available for issuance pursuant to ISO Awards. 
  

	4.	 Administration 

(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 Reporting Persons (or other officers) to make Awards to Eligible Persons who are not Reporting Persons (or other officers whom the Committee has specifically authorized to make Awards). 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, and to recognize differences in foreign law, tax policies, or customs; and 

(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 Reporting Persons, 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. 
  

	5.	 Eligibility 

(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) Reserved. 

(d) 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. 

 

	6.	 Option Awards 

(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 Grant Date. 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 Grant Date. In the case of an ISO granted to an Employee who is a Ten
Percent Holder on the Grant Date, the term of the ISO shall not exceed five years from the Grant Date. 

  
 -4- 

 (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 Grant Date 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 Grant Date. 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 Grant Date. 

(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 100% of the Fair Market Value per Share on the Grant Date; 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 Grant Date 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; 

  
 -5- 

 (iii) 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 
 (iv) 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.

 (iv) Death. In the event of the death of a Participant during the period of Continuous Service since the Grant Date
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. 

  
 -6- 

 (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) Buyout
Provisions. The Committee may at any time offer to buy out an Option, in exchange for a payment in cash or Shares, based on such terms and conditions as the Committee shall establish and communicate to the Participant at the time that
such offer is made. In addition, but subject to any Shareholder approval requirement of applicable law, if the Fair Market Value for Shares subject to an Option is more than 33% below their exercise price for more than 30 consecutive business days,
the Committee may unilaterally terminate and cancel the Option either (i) by paying the Participant, in cash or Shares, an amount not less than the Black-Scholes value of the vested portion of the Option, (ii) by irrevocably committing to
grant, on any date the Committee designates, a new Award other an Option or SAR, or (iii) by irrevocably committing to grant a new Option, on a designated date more than six months after such termination and cancellation of such Option (but
only if the Participant’s Continuous Service has not terminated prior to such designated date), on substantially the same terms as the cancelled Option, provided that the per Share exercise price for the new Option shall equal the per Share
Fair Market Value of a Share on the date the new grant occurs. 
 (k) 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 Grant Date, 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. 
  

	7.	 Share Appreciate Rights (SARs) 

(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. 

  
 -7- 

 (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, and may be payable in cash or Shares based on the spread between the exercise price
of the SAR, and (A) a price based upon or equal to the Fair Market Value of the Shares during a specified period, at a specified time within a specified period before, after or including the date of such event, or (B) a price related to
consideration payable to Company’s shareholders generally in connection with the event. 
 (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 100% of 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) and 6(j) hereof. 

(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 Grant Date. 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. The number of Shares subject to the SAR and the related Option of the Participant will, however, be reduced by the number of underlying Shares
as to which the exercise relates, unless the Award Agreement otherwise provides. 
 (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. 

  
 -8- 

 (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. In any
event, cash shall be paid in lieu of fractional 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. 
 (h) Repricing and Buy-out. The Committee has the
same discretion to reprice and to buy-out SARs as it has to take such actions pursuant to Section 6(j) above with respect to Options. 

 

	8.	 Restricted Shares, Restricted Share Units, and Unrestricted Shares 

(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. 

  
 -9- 

 (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, and cash shall be paid in lieu thereof. 

(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 (plus, in the discretion of the Committee, simple interest at a rate as the Committee may
determine) and a number of Shares equal to any stock dividends, which were declared and paid to the holders of Shares between the Grant Date 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. 
 (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. If a Participant who has received Restricted Share Units provides the Committee with written notice of his or her intention to
make a Section 83(b) Election with respect to the Shares subject to such Restricted Share Units, the Committee may in its discretion convert the Participant’s Restricted Share Units into Restricted Shares, on a one-for-one basis, in full satisfaction of the Participant’s Restricted Share Unit Award. The Participant may then make a Section 83(b) Election with respect to
those 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. 

(g) Deferral Elections. At any time within the thirty-day period (or other shorter or longer
period that the Committee selects) in which a Participant who is a member of a select group of management or highly compensated employees (within the meaning of the Code) receives an Award of either Restricted Shares or Restricted Share Units,
the Committee may permit the Participant to irrevocably elect, on a form provided by and acceptable to the Committee, to defer the receipt of all or a percentage of the Shares that would otherwise be transferred to the Participant upon the vesting
of such Award. If the Participant makes this election, the Shares subject to the election, and any associated dividends and interest, shall be credited to an account established pursuant to Section 9 hereof on the date such Shares would
otherwise have been released or issued to the Participant pursuant to Section 8(d) above. 

  
 -10- 

	9.	 Deferred Share Units 

(a) Elections to Defer. The Committee may permit any Eligible Person who is a Director, Consultant or member of a select group of
management or highly compensated employees (within the meaning of the Code) to irrevocably elect, on a form provided by and acceptable to the Committee (the “Election Form”), to forego the receipt of cash or other compensation (including
the Shares deliverable pursuant to any Award other than Restricted Shares for which a Section 83(b) Election has been made), and in lieu thereof to have the Company credit to an internal Plan account (the “Account”) a number of
deferred share units (“Deferred Share Units”) having a Fair Market Value equal to the Shares and other compensation deferred. These credits will be made at the end of each calendar quarter (or other period that the Administrator
establishes prospectively) during which compensation is deferred. Unless, within five business days after the Company receives an election form, the Company sends the Participant a written notice explaining why it is invalid, each Election Form
shall take effect on the first day of the next calendar year (or on the first day of the next calendar month in the case of an initial election by a Participant who is first eligible to defer hereunder) after its delivery to the Company, subject to
Section 8(g) regarding deferral of Restricted Shares and Restricted Share Units and to Section 10(e) regarding deferral of Performance Awards. Notwithstanding the foregoing sentence: (i) Election Forms shall be ineffective with
respect to any compensation that a Participant earns before the date on which the Company receives the Election Form, and (ii) the Committee may unilaterally make awards in the form of Deferred Share Units, regardless of whether or not the
Participant foregoes other compensation. 
 (b) Vesting. Unless an Award Agreement expressly provides otherwise, each Participant
shall be 100% vested at all times in any Shares subject to Deferred Share Units. 
 (c) Issuances of Shares. The Company shall
provide a Participant with one Share for each Deferred Share Unit in five substantially equal annual installments that are issued before the last day of each of the five calendar years that end after the date on which the Participant’s
Continuous Service terminates, unless – 
 (i) the Participant has properly elected a different form of
distribution, on a form approved by the Committee, that permits the Participant to select any combination of a lump sum and annual installments that are completed within ten years following termination of the Participant’s Continuous Service,
and 
 (ii) the Company received the Participant’s distribution election form at the time the Participant elects to
defer the receipt of cash or other compensation pursuant to Section 9(a), provided that (subject to any prospective changes that the Administrator communicates in writing to a Participant), the Participant may change such election through any
subsequent election that (i) is delivered to the Administrator at least one year before the date on which distributions are otherwise scheduled to commence pursuant to the Participant’s election, and (ii) defers the commencement of
distributions by at least five years from the originally scheduled commencement date. 
 Fractional shares shall not be issued, and instead
shall be paid out in cash. 

  
 -11- 

 (d) Crediting of Dividends. Whenever Shares are issued to a Participant pursuant to
Section 9(c) above, such Participant shall also be entitled to receive, with respect to each Share issued, a cash amount equal to any cash dividends (plus simple interest at a rate of five percent per annum, or such other reasonable rate
as the Committee may determine in an Award Agreement), and a number of Shares equal to any stock dividends which were declared and paid to the holders of Shares between the Grant Date and the date such Share is issued. 

(e) Emergency Withdrawals. In the event a Participant suffers an unforeseeable emergency within the contemplation of this Section
and Section 409A of the Code, the Participant may apply to the Company for an immediate distribution of all or a portion of the Participant’s Deferred Share Units. The unforeseeable emergency must result from a sudden and unexpected
illness or accident of the Participant, the Participant’s spouse, or a dependent (within the meaning of Section 152(a) of the Code) of the Participant, casualty loss of the Participant’s property, or other similar extraordinary and
unforeseeable conditions beyond the control of the Participant. Examples of purposes which are not considered unforeseeable emergencies include post-secondary school expenses or the desire to purchase a residence. In no event will a distribution be
made to the extent the unforeseeable emergency could be relieved through reimbursement or compensation by insurance or otherwise, or by liquidation of the Participant’s nonessential assets to the extent such liquidation would not itself cause a
severe financial hardship. The amount of any distribution hereunder shall be limited to the amount necessary to relieve the Participant’s unforeseeable emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the
distribution. The Committee shall determine whether a Participant has a qualifying unforeseeable emergency and the amount which qualifies for distribution, if any. The Committee may require evidence of the purpose and amount of the need, and may
establish such application or other procedures as it deems appropriate. 
 (f) Unsecured Rights to Deferred Compensation. A
Participant’s right to Deferred Share Units shall at all times constitute an unsecured promise of the Company to pay benefits as they come due. The right of the Participant or the Participant’s duly-authorized transferee to receive
benefits hereunder shall be solely an unsecured claim against the general assets of the Company. Neither the Participant nor the Participant’s duly-authorized transferee shall have any claim against or rights in any specific assets, shares, or
other funds of the Company. 
  

	10.	 Performance Awards 

(a) Performance Units. Subject to the limitations set forth in paragraph (c) hereof, the Committee may in its discretion
grant Performance Units to any Eligible Person and shall evidence such grant in an Award Agreement that is delivered to the Participant which sets forth the terms and conditions of the Award. A Performance Unit 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. 

(b) Performance Compensation Awards. Subject to the limitations set forth in paragraph (c) hereof, the Committee may, at the
time of grant of a Performance Unit, designate such Award as a “Performance Compensation Award” in order that such Award constitutes “qualified performance-based compensation” under Code Section 162(m), in which event the
Committee shall have the power to grant such Performance Compensation Award upon terms and conditions that qualify it as “qualified performance-based compensation” within the meaning of Code Section 162(m). With respect to each such
Performance Compensation Award, the Committee shall establish, in writing within the time required under Code Section 162(m), a “Performance Period,” “Performance Measure(s)”, and “Performance Formula(e)” (each
such term being hereinafter defined). Once 

	
	

  
 -12- 

 established for a Performance Period, the Performance Measure(s) and Performance Formula(e) shall not be
amended or otherwise modified to the extent such amendment or modification would cause the compensation payable pursuant to the Award to fail to constitute qualified performance-based compensation under Code Section 162(m). 

A Participant shall be eligible to receive payment in respect of a Performance Compensation Award only to the extent that the Performance
Measure(s) for such Award is achieved and the Performance Formula(e) as applied against such Performance Measure(s) determines that all or some portion of such Participant’s Award has been earned for the Performance Period. As soon as
practicable after the close of each Performance Period, the Committee shall review and certify in writing whether, and to what extent, the Performance Measure(s) for the Performance Period have been achieved and, if so, determine and certify in
writing the amount of the Performance Compensation Award to be paid to the Participant and, in so doing, may use negative discretion to decrease, but not increase, the amount of the Award otherwise payable to the Participant based upon such
performance. 
 (c) Limitations on Awards. The maximum Performance Unit Award and the maximum Performance Compensation Award
that any one Participant may receive for any one Performance Period shall not together exceed 50,000 Shares and $250,000 in cash. The Committee shall have the discretion to provide in any Award Agreement that any amounts earned in excess of these
limitations will either be credited as Deferred Share Units, or as deferred cash compensation under a separate plan of the Company (provided in the latter case that such deferred compensation either bears a reasonable rate of interest or has a value
based on one or more predetermined actual investments). Any amounts for which payment to the Participant is deferred pursuant to the preceding sentence shall be paid to the Participant in a future year or years not earlier than, and only to the
extent that, the Participant is either not receiving compensation in excess of these limits for a Performance Period, or is not subject to the restrictions set forth under Section 162(m) of the Code. 

(d) Definitions. 

(i) “Performance Formula” means, for a Performance Period, one or more objective formulas or standards established by
the Committee for purposes of determining whether or the extent to which an Award has been earned based on the level of performance attained or to be attained with respect to one or more Performance Measure(s). Performance Formulae may vary from
Performance Period to Performance Period and from Participant to Participant and may be established on a stand-alone basis, in tandem or in the alternative. 

(ii) “Performance Measure” means one or more of the following selected by the Committee to measure Company,
Affiliate, and/or business unit performance for a Performance Period, whether in absolute or relative terms (including, without limitation, terms relative to a peer group or index): basic, diluted, or adjusted earnings per share; sales or revenue;
earnings before interest, taxes, and other adjustments (in total or on a per share basis); basic or adjusted net income; returns on equity, assets, capital, revenue or similar measure; economic value added; working capital; total shareholder return;
and product development, product market share, research, licensing, litigation, human resources, information services, mergers, acquisitions, sales of assets of Affiliates or business units. Each such measure shall be, to the extent applicable,
determined in accordance with 

  
 -13- 

 generally accepted accounting principles as consistently applied by the Company (or such
other standard applied by the Committee) and, if so determined by the Committee, and in the case of a Performance Compensation Award, to the extent permitted under Code Section 162(m), adjusted to omit the effects of extraordinary items, gain
or loss on the disposal of a business segment, unusual or infrequently occurring events and transactions and cumulative effects of changes in accounting principles. Performance Measures may vary from Performance Period to Performance Period and from
Participant to Participant, and may be established on a stand-alone basis, in tandem or in the alternative. 
 (iii)
“Performance Period” means one or more periods of time (of not less than one fiscal year of the Company), as the Committee may designate, over which the attainment of one or more Performance Measure(s) will be measured for the purpose of
determining a Participant’s rights in respect of an Award. 
 (e) Deferral Elections. At any time prior to the date that is at
least six months before the close of a Performance Period (or shorter or longer period that the Committee selects) with respect to an Award of either Performance Units or Performance Compensation, the Committee may permit a Participant who is
a member of a select group of management or highly compensated employees (within the meaning of the Code) to irrevocably elect, on a form provided by and acceptable to the Committee, to defer the receipt of all or a percentage of the cash or Shares
that would otherwise be transferred to the Participant upon the vesting of such Award. If the Participant makes this election, the cash or Shares subject to the election, and any associated interest and dividends, shall be credited to an account
established pursuant to Section 9 hereof on the date such cash or Shares would otherwise have been released or issued to the Participant pursuant to Section 10(a) or Section 10(b) above. 

 

	11.	 Taxes 

(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) Default Rule for Employees. In the absence of any other arrangement, an Employee shall be deemed to have directed the Company
to withhold or collect from his or her cash compensation an amount sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of the exercise of an Award. 

(c) Special Rules. In the case of a Participant other than an Employee (or in the case of an Employee where the next payroll
payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the absence of any other arrangement and to the extent permitted under Applicable Law, the Participant shall be deemed to have elected to
have the Company withhold from the Shares or cash to be issued pursuant to an Award that number of 

  
 -14- 

 Shares having a Fair Market Value determined as of the applicable Tax Date (as defined below) or cash equal
to the amount required to be withheld. For purposes of this Section 11, the Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined under the Applicable Law (the
“Tax Date”). 
 (d) 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). 
 (e) 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 discretion to organize any deferral program, to require deferral election forms, and to
grant or to unilaterally modify any Award in a manner that (i) conforms with the requirements of Section 409A of the Code with respect to compensation that is deferred and that vests after December 31, 2004, (ii) voids any Participant
election to the extent it would violate Section 409A of the Code, and (iii) for any distribution event or election that could be expected to violate Section 409A of the Code, make the distribution only upon the earliest of the first
to occur of a “permissible distribution event” within the meaning of Section 409A of the Code, or a distribution event that the Participant elects in accordance with Section 409A of the Code. 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. 
  

	12.	 Non-Transferability of 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), (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, or (iii) by gift to charitable institutions.
“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. 

  
 -15- 

	13.	 Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions

 (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. 
 (b) Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company other than as part of a
Change of 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: 

 

	 	(i)	 arrange for or otherwise provide that each outstanding Award shall be assumed or a substantially similar award
shall be substituted by a successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”) in which case a Participant who is Involuntarily Terminated (as defined below) in connection with, or
within 12 months following the Change in Control shall become fully vested in any assumed or substituted Award held by the terminated Participant at the time of termination; 

 

	 	(ii)	 terminate upon the consummation of the transaction, provided that the vesting of all outstanding Awards shall
accelerate in full as of a date immediately prior to consummation of the Change of Control. To the extent that an Award is not exercised prior to consummation of a transaction in which the Award is not being assumed or substituted, such Award shall
terminate upon such consummation; or 

  

	 	(iii)	 be assumed, or an equivalent award shall be substituted, by any Successor Company. 

  
 -16- 

 For purposes of this section, “Involuntary Termination” means termination
of a Participant’s Continuous Service without Cause ; or by 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 of 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. 
  

	14.	 Time of Granting Awards. 

The date of grant (“Grant Date”) of an Award shall be the date on which the Committee makes the determination granting such Award or
such other date as is determined by the Committee, provided that in the case of an ISO, the Grant Date shall be the later of the date on which the Committee makes the determination granting such ISO or the date of commencement of the
Participant’s employment relationship with the Company. 
  

	15.	 Modification of Awards and Substitution of Options. 

(a) Modification, Extension, and Renewal of Awards. Within the limitations of the Plan, 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. 

(b) Substitution of Options. Notwithstanding any inconsistent provisions or limits under the Plan, in the event the Company or an
Affiliate acquires (whether by purchase, merger or otherwise) all or substantially all of outstanding capital stock or assets of another corporation or in the event of any reorganization or other transaction qualifying under Section 424 of the
Code, the Committee may, in accordance with the provisions of that Section, substitute Options for options under the plan of the acquired company provided (i) the excess of the aggregate fair market value of the shares subject to an option
immediately after the substitution over the aggregate option price of such shares is not more than the similar excess immediately before such substitution and (ii) the new option does not give persons additional benefits, including any
extension of the exercise period. 

  
 -17- 

	16.	 Term of Plan. 

The Plan shall continue in effect for a term of ten (10) years from its effective date as determined under Section 20 below, unless
the Plan is sooner terminated under Section 17 below. 
  

	17.	 Amendment and Termination of the Plan. 

(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. 
  

	18.	 Conditions Upon Issuance of Shares. 

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. 
  

	19.	 Reservation of Shares. 

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. 
  

	20.	 Effective Date. 

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. 

 

	21.	 Controlling Law. 

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 Maryland, 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. 

  
 -18- 

	22.	 Laws And Regulations. 

(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. 

23. No Shareholder Rights. 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. 

24. No Employment Rights. 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.

cause the direction of the management and policies of such Person or the power to elect directors, whether through the ownership of voting securities, by contract or otherwise; and the terms “affiliated,” “controlling” and
“controlled” have meanings correlative to the foregoing. 
 “Applicable Law” means the legal
requirements relating to the administration of options and share-based plans under applicable U.S. federal and state laws, the Code, any applicable stock exchange or automated quotation system rules or regulations, and the applicable laws of
any other country or jurisdiction where Awards are granted, as such laws, rules, regulations and requirements shall be in place from time to time. 

“Award” means any award made pursuant to the Plan, including awards made in the form of an
Option, an SAR, a Restricted Share, a Restricted Share Unit, an Unrestricted Share, a Deferred Share Unit and a Performance Award, or any combination thereof, whether alternative or cumulative, authorized by and granted under this Plan.

“Cause” for termination of a Participant’s Continuous Service will exist if the Participant is

deliberate violation of a material Company policy; (ii) the Participant’s commission of any material act or acts of fraud, embezzlement, dishonesty, or other willful misconduct; (iii) the Participant’s material unauthorized use
or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or her relationship with the Company; or (iv) Participant’s
willful and material breach of any of his or her obligations under any written agreement or covenant with the Company. 

 The Committee shall in its discretion determine whether or not a Participant is being
terminated for Cause. The Committee’s determination shall, unless arbitrary and capricious, be final and binding on the Participant, the Company, and all other affected persons. The foregoing definition does not in any way limit the
Company’s ability to terminate a Participant’s employment or consulting relationship at any time, and the term “Company” will be interpreted herein to include any Affiliate or successor thereto, if appropriate. 

“Change in Control” means the first of the following to occur after the date of adoption of this
Plan (as set forth in Section 4.5.1 hereto), excluding any event that is Management Action:

Controlling Interest. Any Person (other than Persons who are Employees at any time more than one year before a transaction) becomes the Beneficial Owner, directly or indirectly, of

Affiliates by or for the Person shall not be taken into account, and (ii) an agreement to vote securities shall be disregarded unless its ultimate purpose is to cause what would otherwise be Change of Control, as reasonably determined by the

commencing after the date of adoption of this Plan, individuals who constituted the Board at the beginning of the period (or their approved replacements, as defined in the next sentence) cease for any reason to constitute a majority of the
Board. A new Director shall be considered an “approved replacement” Director if his or her election (or nomination for election) was approved by a vote of at least a majority of the Directors then still in office who either were Directors
at the beginning of the period or were themselves approved replacement Directors, but in either case excluding any Director whose initial assumption of office occurred as a result of an actual or threatened solicitation of proxies or consents by or
on behalf of any Person other than the Board. 
 (iii) Merger Approved. The Company consummates a merger, or
consolidation of the Company with any other corporation unless: (a) the voting securities of the Company outstanding immediately before the merger or consolidation would continue to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; and
(b) no Person (other than Persons who are Employees at any time more than one year before a transaction) becomes the Beneficial Owner, directly or indirectly, of securities of the Company representing
50% or more of the combined voting power of the Company’s then outstanding securities.

Assets. The stockholders of the Company approve an agreement for the sale or disposition by the Company of all, or substantially all, of the Company’s assets. 

(v) Liquidation or Dissolution. The stockholders of the Company approve a plan or proposal for liquidation or
dissolution of the Company. 

  
 -2- 

 Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have
occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the record holders of the common stock of the Company immediately prior to such transaction or series of transactions continue
to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions. 

“Code” means the U.S. Internal Revenue Code of 1986, as amended. 

“Committee” means one or more committees or subcommittees of the Board appointed by the Board to

who are “outside directors” within the meaning of Section 162(m) of the Code. With respect to any decision relating to a Reporting Person, the Committee shall consist of two or more Directors who are disinterested within the meaning
of Rule 16b-3.

absence approved by the Committee, provided that such leave is for a period of not more than 90 days, unless reemployment upon the expiration of such leave is guaranteed by contract or statute, or unless provided otherwise pursuant to Company policy
adopted from time to time; (iv) changes in status from Director to advisory director or emeritus status; or (iv) in the case of transfers between locations of the Company or between the Company, its Affiliates or their respective

“Director” means a member of the Board, or a member of the board of directors of an Affiliate.

 “Disabled” means a condition under which a Participant —
