its responsibilities to a Committee, which shall consist of at least two members of the Board. In addition, to the extent permitted by Applicable Law, the Board or the Committee may further delegate its responsibilities to any Employee of the
Company or any Affiliate. Where this Plan specifies that an action is to be taken or a determination made by the Board, only the Board may take that action or make that determination. Where this Plan references the Administrator, the action may be
taken or determination made by the Board, the Committee, or other Administrator. However, only the Board or the Committee may approve grants of Options to Executives, and an Administrator other than the Board or the Committee may grant Options only
within guidelines established by the Board or the Committee. Moreover, all actions and determinations by any Administrator are subject to the provisions of this Plan. 
  

 5 

 (b) So long as the Company has registered and outstanding a class of equity securities under
Section 12 of the Exchange Act and to the extent necessary or helpful to comply with Applicable Law with respect to officers subject to Section 16 of the Exchange Act and/or others, the Committee shall consist of Company Directors who are
“Non-Employee Directors” as defined in Rule 16b-3 and who are “outside directors” as defined in Section 162(m) of the Code.

 (g) to determine the types of payment that may be used to purchase Shares subject to Awards; 
 (h) to determine the types of payment that may be used to satisfy withholding tax obligations; 
 (i) to determine the other terms of each Option or Stock Award, including but not limited to: the time or times at which Options or Stock Awards may
vest, be exercised or settled, or become nonforfeitable (including any acceleration related to such terms), whether and under what conditions an Option or Stock Award is assignable, and whether an Option is a Nonstatutory Option or an Incentive
Stock Option and any other conditions that are to apply to the Award; 
 (j) to modify or amend any Option or Stock Award; 
 (k) to authorize any person to sign any Award Agreement or other document related to this Plan on behalf of the Company;

Event or a Divestiture, then the effect of that Event or Divestiture; and 
 (s) to make all other determinations the Administrator deems

 4.3 Scope of Discretion. Subject to the last sentence of this
Section 4.3, on all matters for which this Plan confers the authority, right, or power on the Board, the Committee, or other Administrator to make decisions, that body may make those decisions in its sole and absolute discretion. Moreover, but
again subject to the last sentence of this Section 4.3, in making those decisions the Board, the Committee, or other Administrator need not treat all persons eligible to receive Awards, all Participants, all Awards or all Shares subject to
Awards the same way. However, the discretion of the Board, the Committee, or other Administrator is subject to the specific provisions and specific limitations of this Plan, as well as all rights conferred on specific Participants by Award
Agreements and other agreements. 
  

	5.	Persons Eligible to Receive Awards 

 5.1 Eligible
Individuals. Options and Stock Awards may be granted to, and only to, Employees, Directors and Consultants, including to prospective Employees, Directors and Consultants conditioned on the beginning of their service for the Company or an
Affiliate, provided that Incentive Stock Options many only be granted to Employees, as provided in Section 7(g). 
 5.2
Section 162(m) Limitation. So long as the Company is a “publicly held corporation” within the meaning of Section 162(m) of the Code, no Employee or prospective Employee may be granted one or more Options or Stock Awards
within any fiscal year of the Company to purchase more than 750,000 Shares, subject to adjustment under Section 11. If an Award is cancelled without being exercised or if the Option Price of an Option is reduced, that cancelled or repriced
Award shall continue to be counted against the limit on Awards that may be granted to any individual under this Section 5.2. 
  

	6.	Terms and Conditions of Options 

 The following
rules apply to all Options: 
 6.1 Price. No Option may have an Option Price less than 50% of the Fair Market Value of the Shares on
the Grant Date. No Option intended as “qualified incentive-based compensation” within the meaning of Section 162(m) of the Code may have an Option Price less than 100% of the Fair Market Value of the Shares on the Grant Date. In no
event will the Option Price of any Option be less than the par value of the Shares issuable under the Option if that is required by Applicable Law. The Option Price of an Incentive Stock Option shall be subject to Section 7(f). 
 6.2 No Option Repricings. Other than in accordance with Section 11, Options may not be repriced, replaced, regranted through cancellation or
modified without stockholder approval, if the effect of the repricing, replacement, regrant or modification would be to reduce the effective Option Price of the Options. 
  

 7 

 6.3 Term. No Option shall be exercisable after its Expiration Date. No Option may have an
Expiration Date that is more than 10 years after its Grant Date. The term of an Incentive Stock Option shall be subject to Sections 7(a) and 7(e). 
 6.4 Vesting. 
 (a) Options shall be exercisable: (a) on the Grant Date, or (b) in accordance
with a schedule related to the Grant Date, the date the Optionee’s directorship, employment, or consultancy begins, or a different date specified in the Option Agreement. If so provided in the Option Agreement, an Option may be exercisable
subject to the application of Reverse Vesting to the Option Shares. The vesting of Incentive Stock Options shall be subject to Section 7(c). 
 (b) The Administrator 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 leave that is not a leave required to be provided to the Optionee under Applicable Law. In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon an
Optionee’s returning from military leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to
Options to the same extent as would have applied had the Optionee continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 
 6.5 Form of Payment 
 (a) The
Administrator shall determine the acceptable form and method of payment for exercising an Option. 
 (b) Acceptable forms of payment for all
Option Shares are cash, check or wire transfer, denominated in U.S. dollars except as specified by the Administrator for non-U.S. Employees or non-U.S. sub-plans. 
 (c) In addition, the Administrator may permit payment of the Option Price to be made by any of the following methods: 
 (i) other Shares, or the designation of other Shares, which (A) if required to avoid the Company’s incurring adverse accounting charges, in the case of Shares acquired upon exercise of an option (whether or
not under this Plan) are “mature” shares for purposes of avoiding variable accounting treatment under generally accepted accounting principals (generally, mature shares are those that have been owned by the Optionee for more than six
months on the date of surrender), and (B) have a Fair Market Value on the date of surrender equal to the Option Price of the Shares as to which the Option is being exercised; 
 (ii) provided that a public market exists for the Shares, through a “same day sale” commitment from the Optionee and a
broker-dealer that is a member of the National Association of Securities Dealers (an “NASD Dealer”) under which the Optionee irrevocably elects to exercise the Option and the NASD Dealer irrevocably commits to forward an
amount equal to the Option Price plus any applicable withholding taxes, directly to the Company, upon receipt of the Option Shares (a “Cashless Exercise”); 
  

 8 

 (iii) cancellation of any debt owed by the Company or by any Affiliate to the Optionee,
including, without limitation, waiver of compensation due or accrued for services previously rendered to the Company; and 
 (iv) any combination of the methods of payment permitted by any paragraph of this Section 6.5. 
 (d) The Administrator may
also permit any other form or method of payment for Option Shares permitted by Applicable Law. 
 6.6 Nonassignability of Nonstatutory
Options. Except as set forth in any Option Agreement or as determined by the Administrator, no Nonstatutory Option shall be assignable or otherwise transferable by the Optionee except by will or by the laws of descent and distribution; provided
however, Nonstatutory Options may be transferred and exercised in accordance with a Qualified Domestic Relations Order and Nonstatutory Options may be exercised by a guardian or conservator appointed to act for the Optionee. Notwithstanding the
foregoing, Nonstatutory Options may be transferred by instrument to an inter vivos or testamentary trust in which the Nonstatutory Options are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or pursuant to domestic
relations orders to “Immediate Family Members” (as defined below) of the Optionee. “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 (including adoptive relationships), a trust in which these persons have more than fifty percent of the beneficial interest, a foundation in which these
persons (or the Optionee) control the management of assets, and any other entity in which these persons (or the Optionee) own more than fifty percent of the voting interests. Incentive Stock Options may only be assigned subject to Section 7(h).

  

	7.	Incentive Stock Options 

 The following rules apply
only to Incentive Stock Options and only to the extent these rules are more restrictive than the rules that would otherwise apply under this Plan. With the consent of the Optionee, or where this Plan provides that an action may be taken
notwithstanding any other provision of this Plan, the Administrator may deviate from the requirements of this Section, notwithstanding that any Incentive Stock Option modified by the Administrator will thereafter be treated as a Nonstatutory Option.

 (a) The Expiration Date of an Incentive Stock Option shall not be later than 10 years from its Grant Date, with the result that no
Incentive Stock Option may be exercised after the expiration of 10 years from its Grant Date. 
 (b) No Incentive Stock Option may be granted
more than 10 years from the date this Plan was approved by the Board. 
 (c) Options intended to be Incentive Stock Options that are granted
to any single Optionee under all incentive stock option plans of the Company and its Affiliates, including Incentive Stock Options granted under this Plan, may not become exercisable at a rate of more than $100,000 in Fair Market Value of stock
(measured on the grant dates of the options) during any calendar year. For this purpose, an Option becomes exercisable with respect to a given share of stock the first time its holder may purchase that share, notwithstanding any right of the Company
to repurchase that share. Unless the Administrator specifies otherwise in the related agreement governing the Option, this limitation shall be applied by, to the extent necessary to satisfy this $100,000 rule, treating certain stock options that
were intended to be Incentive Stock Options as Nonstatutory Options. The stock options or portions of stock options to be reclassified as Nonstatutory Options are those with the highest option prices, whether granted under this Plan or any 

  

 9 

 
other equity compensation plan of the Company or any Affiliate that permits that treatment. This Section 7(c) shall not cause an Incentive Stock Option
to become exercisable before its original vesting or exercisability date or cause an Incentive Stock Option that has already vested or become exercisable to cease to be vested or exercisable. 
 (d) In order for an Incentive Stock Option to be exercised for any form of payment other than those described in Section 6.5(b), that right must be
stated in the Option Agreement relating to that Incentive Stock Option. 
 (e) Any Incentive Stock Option granted to a Ten Percent
Stockholder, must have an Expiration Date that is not later than five years from its Grant Date, with the result that no such Option may be exercised after the expiration of five years from the Grant Date. A “Ten Percent
Stockholder” is any person who, directly or by attribution under Section 424(d) of the Code, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of any Affiliate on the
Grant Date. 
 (f) The Option Price of an Incentive Stock Option shall never be less than the Fair Market Value of the Shares at the Grant
Date. The Option Price for the Shares covered by an Incentive Stock Option granted to a Ten Percent Stockholder shall never be less than 110% of the Fair Market Value of the Shares at the Grant Date. 
 (g) Incentive Stock Options may be granted only to Employees. If an Optionee changes status from an Employee to a Consultant, that Optionee’s
Incentive Stock Options become Nonstatutory Options if not exercised within the time period described in Section 7(i). 
 (h) No rights
under an Incentive Stock Option may be transferred by the Optionee, other than by will or the laws of descent and distribution. During the life of the Optionee, an Incentive Stock Option may be exercised only by the Optionee. 
 (i) An Incentive Stock Option shall be treated as a Nonstatutory Option if it remains exercisable after, and is not exercised within, the three-month
period beginning with the Optionee’s Termination for any reason other than the Optionee’s death or disability (as defined in Section 22(c) of the Code). In the case of Termination due to death, an Incentive Stock Option shall continue
to be treated as an Incentive Stock Option if it remains exercisable after, but is not exercised within, the one year period provided it is exercised before the Expiration Date. In the case of Termination due to disability, an Incentive Stock Option
shall be treated as a Nonstatutory Option if it remains exercisable after, but is not exercised within, one year after the Optionee’s Termination. 
 (j) An Incentive Stock Option may be modified by the Board. 
  

	8.	Exercise of Options 

 8.1 In General. An
Option shall be exercisable in accordance with this Plan, the Option Agreement under which it is granted, and as prescribed by the Administrator. 
 8.2 Time of Exercise. An Option shall be considered exercised when the Company receives: (a) written notice of exercise from the person entitled to exercise the Option, (b) full payment, or provision for payment, in a form
and method approved by the Administrator, for the Shares for which the Option is being exercised, and (c) with respect to Nonstatutory Options, payment, or provision for payment, in a form approved by the Administrator, of all applicable
withholding taxes due upon exercise. An Option may not be exercised for a fraction of a Share. 
  

 10 

 8.3 Issuance of Option Shares. The Company shall issue Option Shares in the name of the person
properly exercising the Option. If the Optionee is that person and so requests, the Option Shares shall be issued in the name of the Optionee and the Optionee’s spouse. The Company shall endeavor to issue Option Shares promptly after an Option
is exercised. However, until Option Shares are actually issued, as evidenced by the appropriate entry on the stock books of the Company or its transfer agent, no right to vote or receive dividends or other distributions, and no other rights as a
stockholder, shall exist with respect to the Option Shares, even though the Optionee has completed all the steps necessary to exercise the Option. No adjustment shall be made for any dividend, distribution, or other right for which the record date
precedes the date the Option Shares are issued, except as provided in Section 11. 
 8.4 Termination 
 (a) In General. Except as provided in an Option Agreement or in writing by the Administrator, and as otherwise provided in
Sections 8.4(b), (c), (d), (e), (f), (g) and (h), after an Optionee’s Termination the Optionee’s Options shall be exercisable to the extent (but only to the extent) they are vested on the date of that Termination and only during
the three months (or such other period of time as is determined by the Administrator) after the Termination, but in no event after the Expiration Date. To the extent the Optionee does not exercise an Option within the time specified for exercise,
the Option shall automatically terminate. 
 (b) Leaves of Absence. Unless otherwise provided in the Option Agreement, no
Option may be exercised more than three months (or such other period of time as is determined by the Administrator) after the beginning of a leave of absence, other than a personal, medical or military leave approved by the Administrator with
employment guaranteed upon return. 
 (c) Death or Disability. Unless otherwise provided by the Administrator or in the Option
Agreement, if an Optionee’s Termination is due to death or disability (as determined by the Administrator with respect to Nonstatutory Options and as defined by Section 22(e) of the Code with respect to Incentive Stock Options), all
Options of that Optionee to the extent they are vested at the date of that Termination may be exercised for one year (or such other period of time as is determined by the Administrator) after that Termination, but in no event after the Expiration
Date. In the case of Termination due to death, an Option may be exercised as provided in Section 19. In the case of Termination due to disability, if a guardian or conservator has been appointed to act for the Optionee and been granted this
authority as part of that appointment, that guardian or conservator may exercise the Option on behalf of the Optionee. Death or disability occurring after an Optionee’s Termination shall not cause the Termination to be treated as having
occurred due to death or disability. To the extent an Option is not so exercised within the time specified for its exercise, the Option shall automatically terminate. 
 (d) Divestiture. If an Optionee’s Termination is due to a Divestiture, the Board may take any one or more of the actions described in Section 11.3 or 11.5. 
 (e) Retirement. Unless otherwise provided in the Option Agreement or by the Administrator in writing, if an Optionee’s Termination is
due to the Optionee’s retirement in accordance with the Company’s or an Affiliate’s retirement policy, all Options of that Optionee to the extent they are vested at the Optionee’s date of retirement may be exercised for three
months (or such other period of time as is determined by the Administrator) after the Optionee’s date of retirement, but in no event after the Expiration Date. To the extent the Optionee does not exercise an Option within the time specified for
exercise, the Option shall automatically terminate. 
 (f) Severance Programs. Unless otherwise provided in the Option
Agreement or by the Administrator in writing, if an Optionee’s Termination results from participation in a voluntary severance incentive program of the Company or an Affiliate 

  

 11 

 
approved by the Board, all Options of that Employee to the extent they are vested at the time of that Termination shall be exercisable for three months (or
such other period of time as is determined by the Administrator) after the Optionee’s Termination, but in no event after the Expiration Date. If the Optionee does not exercise an Option within the time specified for exercise, the Option shall
automatically terminate. 
 (g) Termination for Cause. If an Optionee’s Termination is due to Cause (as defined below),
all of the Optionee’s Options shall automatically terminate and cease to be exercisable at the time of such termination and all Options exercised after the first event constituting Cause may be rescinded by the Administrator. “Cause”
means breach of any provision of a Key Employment Agreement, Secure Computing Corporation Employment Agreement or any other agreement between the Company or any of its Affiliates and an Optionee, employment-related dishonesty, fraud, misconduct or
disclosure or misuse of confidential information, or other employment-related conduct that is likely to cause significant injury to the Company, an Affiliate, or any of their respective employees, officers or directors (including, without
limitation, commission of a felony or similar offense), in each case as determined by the Administrator. “Cause” shall not require that a civil judgment or criminal conviction have been entered against or guilty plea shall have been made
by the Optionee regarding any of the matters referred to in the previous sentence. Accordingly, the Administrator shall be entitled to determine “Cause” based on the Administrator’s good faith belief. If the Optionee is criminally
charged with a felony or similar offense, that shall be a sufficient, but not a necessary, basis for such a belief. 
 9. Stock Grants and Stock Unit
Awards. Each Stock Award Agreement reflecting the issuance of a Stock Grant or Stock Unit shall be in such form and shall contain such terms and conditions as the Administrator shall deem appropriate. The terms and conditions of such agreements
may change from time to time, and the terms and conditions of separate agreements need not be identical, but each such agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions: 
 9.1 Consideration. A Stock Grant or Stock Unit may be awarded in consideration for such property
or services as is permitted under Applicable Law, including for past services actually rendered to the Company or an Affiliate for its benefit. 
 9.2 Vesting. Shares of Common Stock awarded under an agreement reflecting a Stock Grant and a Stock Unit award may, but need not, be subject to a share repurchase option, forfeiture restriction or other conditions in favor of the
Company in accordance with a vesting or lapse schedule to be determined by the Administrator. 
 9.3 Termination. In the event of a
Participant’s Termination, the Company may reacquire any or all of the Shares held by the Participant which have not vested or which are otherwise subject to forfeiture or other conditions as of the date of Termination under the terms of the
Stock Award Agreement. 
 9.4 Transferability. Except as determined by the Board and reflected in the Stock Award Agreement, no rights
to acquire Shares under a Stock Grant or a Stock Unit shall be assignable or otherwise transferable by the Participant except by will or by the laws of descent and distribution. 
  

	10.	Stock Appreciation Rights 

 10.1 In General.
Stock Appreciation Rights may be granted either alone, in addition to, or in tandem with other Awards granted under the Plan. The Administrator may grant Stock Appreciation Rights to eligible Participants subject to terms and conditions not
inconsistent with this Plan and determined by the Administrator. The specific terms and conditions applicable to the Participant shall be provided for in the Stock Award Agreement. Stock Appreciation Rights shall be exercisable, in whole or in part,
at such times as the Administrator shall specify in the Stock Award Agreement. 
  

 12 

 10.2 Exercise of Stock Appreciation Right. Upon the exercise of a Stock Appreciation Right, in
whole or in part, the Participant shall be entitled to a payment in an amount equal to the excess of the Fair Market Value on the date of exercise of a fixed number of Shares covered by the exercised portion of the Stock Appreciation Right, over the
Fair Market Value on the grant date of the Shares covered by the exercised portion of the Stock Appreciation Right (or if reflected in the Stock Award Agreement, such other amount calculated with respect to Shares subject to the award as the
Administrator may determine). The amount due to the Participant upon the exercise of a Stock Appreciation Right shall be paid in such form of consideration as determined by the Administrator and may be in cash, Shares or a combination thereof, over
the period or periods specified in the Stock Award Agreement. A Stock Award Agreement may place limits on the amount that may be paid over any specified period or periods upon the exercise of a Stock Appreciation Right, on an aggregate basis or as
to any Participant. A Stock Appreciation Right shall be considered exercised when the Company receives written notice of exercise in accordance with the terms of the Stock Award Agreement from the person entitled to exercise the Stock Appreciation
Right. 
 10.3 Transferability. Except as determined by the Board and reflected in the Stock Award Agreement, no Stock Appreciation
Rights shall be assignable or otherwise transferable by the Participant except by will or by the laws of descent and distribution. 
  

	11.	Certain Transactions and Events 

 11.1 In
General. Except as provided in this Section 11, no change in the capital structure of the Company, merger, sale, or other disposition of assets or a subsidiary, change of control, issuance by the Company of shares of any class of securities
convertible into shares of any class, conversion of securities, or other transaction or event shall require or be the occasion for any adjustments of the type described in this Section 11. 
 11.2 Changes in Capital Structure. In the event of any stock split, reverse stock split, recapitalization, combination or reclassification of
stock, stock dividend, spin-off, or similar change to the capital structure of the Company (not including a Fundamental Transaction or an Event), the Board shall make whatever adjustments it concludes are appropriate to: (a) the number and type
of Awards that may be granted under this Plan, (b) the number and type of Awards that may be granted to any individual under this Plan, including under Section 5.2 of this Plan, (c) the Option Price or Stock Award price, if any, and
number and class of securities issuable under each outstanding Award, and (d) the repurchase price of any securities substituted for Award Shares that are subject to repurchase rights. The specific adjustments shall be determined by the Board
in its sole and absolute discretion. Unless the Board specifies otherwise, any securities issuable as a result of any such adjustment shall be rounded to the next lower whole security. 
 11.3 Fundamental Transactions. If the Company merges with another entity in a transaction in which the Company is not the surviving entity or if,
as a result of any other transaction or event, other securities are substituted for the Shares or Shares may no longer be issued (each a “Fundamental Transaction”), then, notwithstanding any other provision of this Plan, the
Board shall do one or more of the following contingent on the closing or completion of the Fundamental Transaction: (a) arrange for the substitution in exchange for Awards of awards on equity securities other than Shares (including, if
appropriate, equity securities of an entity other than the Company) (an “assumption” of Options) on such terms and conditions as the Board determines are appropriate, (b) accelerate the vesting and/or exercisability and
termination of any restrictions of outstanding Awards, in whole or in part, so that 

  

 13 

 
Awards can be exercised before or otherwise in connection with the closing or completion of a Fundamental Transaction or event but then terminate,
(c) cancel or arrange for the cancellation of Awards in exchange for cash payments to Participants, and (d) either arrange for any repurchase rights of the Company with respect to Award Shares to apply to the securities issued in
substitution for Shares or terminate repurchase rights on Award Shares. The Board need not adopt the same rules for each Award or each Participant. 
 11.4 Events. The majority of the “Incumbent Board” (as defined below) may also, but need not, specify that other transactions or events constitute an “Event,” as set forth below. In connection with
an Event, notwithstanding any other provision of this Plan, the Incumbent Board may take any one or more of the actions described in Section 11.3. In addition, the Incumbent Board may extend the date for the exercise of Options (but not beyond
their original Expiration Date). The Incumbent Board need not adopt the same rules for each Award or each Participant. Examples of transactions or events that the Incumbent Board may treat as an Event are: 
 (1) The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) of beneficial
ownership (within the meaning of Exchange Act Rule 13d-3) of 20% (except for acquisitions by any individual, entity or group that, prior to the Effective Date, owns 20% or more of any class of capital stock of the Company) or more of either
(i) the then outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (ii) the combined voting power of the then outstanding voting securities of the Company entitled to vote
generally in the election of the Board (the “Outstanding Company Voting Securities”); provided, however, that the following acquisitions shall not constitute an Event: 
 (A) any acquisition of voting securities of the Company directly from the Company, 
 (B) any acquisition of voting securities of the Company by the Company or any of its wholly owned “Subsidiaries” (as defined in
Section 424 of the Code), 
 (C) any acquisition of voting securities of the Company by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any of its Subsidiaries, or 
 (D) any acquisition by any corporation with respect to which,
immediately following such acquisition, more than 60% of respectively, the then outstanding shares of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote
generally in the election of directors is then beneficially owned, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and
Outstanding Company Voting Securities immediately prior to such acquisition in substantially the same proportions as was their ownership, immediately prior to such acquisition, of the Outstanding Company Common Stock and Outstanding Company Voting
Securities, as the case may be; 
 (2) Individuals who, as of the Effective Date, constitute the Board (the “Incumbent
Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a Company Director subsequent to the Effective Date whose election, or nomination for election by the
Company’s stockholders, was approved by a vote of at least a majority of the Company Directors then comprising the Incumbent Board shall be considered a member of the Incumbent Board, but excluding, for this purpose, any such individual whose
initial assumption of office occurs as a result of an actual or threatened election contest which was (or, if threatened, would have been) subject to Exchange Act Rule 14a-11; 
  

 14 

 (3) Approval by the stockholders of the Company of a reorganization, merger, consolidation or statutory
exchange of Outstanding Company Voting Securities, unless immediately following such reorganization, merger, consolidation or exchange, all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the
Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such reorganization, merger, consolidation or exchange beneficially own, directly or indirectly, more than 60% of, respectively, the then outstanding
shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such reorganization, merger, consolidation
or exchange in substantially the same proportions as was their ownership, immediately prior to such reorganization, merger, consolidation or exchange, of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may
be; or 
 (4) Approval by the stockholders of the Company of (i) a complete liquidation or dissolution of the Company or (ii) the
sale or other disposition of all or substantially all of the assets of the Company, other than to a corporation with respect to which, immediately following such sale or other disposition, more than 60% of, respectively, the then outstanding shares
of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in the election of directors is then beneficially owned, directly or indirectly, by all or
substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such sale or other disposition in substantially
the same proportion as was their ownership, immediately prior to such sale or other disposition, of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be. 
 Notwithstanding the above, an Event shall not be deemed to occur with respect to a Participant if the acquisition of the 20% or greater interest referred
to in paragraph (1) is by a group, acting in concert, that includes that Participant or if at least 40% of the then outstanding common stock or combined voting power of the then outstanding voting securities (or voting equity interests) of the
surviving corporation or of any corporation (or other entity) acquiring all or substantially all of the assets of the Company shall be beneficially owned, directly or indirectly, immediately after a reorganization, merger, consolidation, statutory
share exchange or sale or other disposition of assets referred to in paragraphs (3) or (4) by a group, acting in concert, that includes that Participant. 
 11.5 Divestiture. If the Company or an Affiliate sells or otherwise transfers equity securities of an Affiliate to a person or entity other than the Company or an Affiliate, or leases, exchanges or transfers
all or any portion of its assets to such a person or entity, then the Board, in its sole and absolute discretion, may specify that such transaction or event constitutes a “Divestiture”. In connection with a Divestiture,
notwithstanding any other provision of this Plan, the Board may take one or more of the actions described in Section 11.3 with respect to Awards or Award Shares held by, for example, Employees, Directors or Consultants for whom that transaction
or event results in a Termination. The Board need not adopt the same rules for each Award or each Participant. 
 11.6 Dissolution. If
the Company adopts a plan of dissolution, the Board may, in its sole and absolute discretion, cause Awards to be fully vested and exercisable (but not after their Expiration Date) before the dissolution is completed but contingent on its completion
and may cause the Company’s repurchase rights on Award Shares to lapse upon completion of the dissolution. To the extent not exercised or settled before the earlier of the completion of the dissolution or their Expiration Date, Awards shall
terminate just before the dissolution is completed. The Board need not adopt the same rules for each Award or each Participant. 
  

 15 

 11.7 Cut-Back to Preserve Benefits. If the Administrator determines that the net after-tax amount
to be realized by any Participant, taking into account any accelerated vesting, termination of repurchase rights, or cash payments to that Participant in connection with any transaction or event addressed in this Section 11, would be greater if
one or more of those steps were not taken with respect to that Participant’s Awards or Award Shares, then and to that extent one or more of those steps shall not be taken. 
 11.8 Substitute Awards. The Board may cause the Company to grant Substitute Awards in connection with the acquisition by the Company or an
Affiliate of equity securities of any entity (including by merger) or all or a portion of the assets of any entity. Any such substitution shall be effective when the acquisition closes. Unless and to the extent specified otherwise by the Board,
Substitute Awards shall have the same terms and conditions as the options they replace, except that (subject to Section 11) Substitute Awards shall be Awards to purchase Shares rather than equity securities of the granting entity and shall have
an exercise or purchase price that, as determined by the Board in its sole and absolute discretion, properly reflects the substitution. 
  

	12.	Withholding and Tax Reporting 

 12.1 Tax
Withholding Option 
 (a) General. Whenever Award Shares are granted, vest, transferred, purchased, issued or become free of
restrictions, the Company may require the Participant to remit to the Company an amount sufficient to satisfy any applicable tax withholding requirement, whether the related tax is imposed on the Participant or the Company. The Company shall have no
obligation to deliver Award Shares or release Award Shares from an escrow or permit a transfer of Award Shares until the Participant has satisfied those tax withholding obligations. Whenever payment in satisfaction of Awards is made in cash, the
payment will be reduced by an amount sufficient to satisfy all tax withholding requirements. 
 (b) Method of Payment. The
Participant shall pay any required withholding using the forms of consideration described in Section 6.5(b), except that, in the discretion of the Administrator, the Company may also permit the Participant to use any of the forms of payment
described in Section 6.5(c). The Administrator may also permit Award Shares to be withheld to pay required withholding. If the Administrator permits Award Shares to be withheld, the Fair Market Value of the Award Shares withheld shall not
exceed the amount determined by the applicable minimum statutory withholding rates and shall be determined as of the date that the amount of tax to be withheld or tendered for this purpose is to be determined. 
 12.2 Reporting of Dispositions. Any holder of Option Shares acquired under an Incentive Stock Option shall promptly notify the Administrator in
writing of the sale or other disposition of any of those Option Shares if the disposition occurs during: (a) the longer of two years after the Grant Date of the Incentive Stock Option and one year after the date the Incentive Stock Option was
exercised, or (b) such other period as the Administrator has established. 
  

	13.	Consulting or Employment Relationship 

 Nothing in
this Plan or in any Award Agreement, and no Award or the fact that Award Shares remain subject to repurchase rights, shall: (a) interfere with or limit the right of the Company or any Affiliate to terminate the employment or consultancy of any
Participant at any time, whether with or without cause or reason, and with or without the payment of severance or any other compensation or payment, or (b) interfere with the application of any provision in any of the Company’s or any
Affiliate’s charter documents or Applicable Law relating to the election, appointment, term of office, or removal of a Director. 
  

 16 

	14.	Section 162(m) Compliance 

 Any Stock Award
(other than an Option or any other Stock Award having a purchase price equal to 100% of the Fair Market Value on the date such Award is made) that is intended as “qualified performance-based compensation” within the meaning of
Section 162(m) of the Code must vest or become exercisable contingent on the achievement of one or more Qualifying Performance Criteria. Notwithstanding anything to the contrary herein, the Committee shall have the discretion to determine the
time and manner of compliance with Section 162(m) of the Code as required under applicable regulations and to conform the procedures related to the Award to the requirements of Section 162(m) of the Code and may reduce the number of Shares
granted or amount of cash or other property to which a Participant may otherwise have been entitled with respect to an Award designed to qualify as performance-based compensation under Section 162(m) of the Code. 
  

	15.	Compliance with Law 

 The grant of Awards and the
issuance and subsequent transfer of Award Shares shall be subject to compliance with all Applicable Laws, including all applicable securities laws. Awards may not be exercised or settled, and Award Shares may not be transferred, in violation of
Applicable Law. Thus, for example, Options may not be exercised unless: (a) a registration statement under the Securities Act is then in effect with respect to the related Option Shares, or (b) in the opinion of legal counsel to the
Company, those Option Shares may be issued in accordance with an applicable exemption from the registration requirements of the Securities Act and any other applicable securities laws. The Company is under no requirement to register any Award
Shares, and the failure or inability of the Company to obtain from any regulatory body the authority considered by the Company’s legal counsel to be necessary or useful for the lawful issuance of any Award Shares or their subsequent transfer
shall relieve the Company of any liability for failing to issue those Award Shares or permitting their transfer. As a condition to the exercise or settlement of any Award or the transfer of any Award Shares, the Company may require the Participant
to satisfy any requirements or qualifications that may be necessary or appropriate to comply with or evidence compliance with any Applicable Law. 
  

	16.	Amendment or Termination of this Plan or Outstanding Awards 

 16.1 Amendment and Termination. The Board may at any time amend, suspend, or terminate this Plan. 
 16.2 Stockholder
Approval. The Company shall obtain the approval of the Company’s stockholders for any amendment to this Plan if stockholder approval is necessary or desirable to comply with any Applicable Laws or with the requirements applicable to the
grant of Options intended to be Incentive Stock Options. The Board may also, but need not, require that the Company’s stockholders approve any other amendments to this Plan. In addition, unless approved by the stockholders of the Company, no
amendment shall be made that would result in a repricing of Options by (x) reducing the exercise price of outstanding Options or (y) canceling an outstanding Option held by a Participant and re-granting to the Participant a new Option with
a lower exercise price, in either case other pursuant to Section 11 of the Plan. 
 16.3 Effect. No amendment, suspension, or
termination of this Plan, and no modification of any Award even in the absence of an amendment, suspension, or termination of this Plan, shall impair any existing contractual rights of any Participant unless the affected Participant consents to the
amendment, suspension, termination, or modification. However, no such consent shall be required 

  

 17 

 
if the Administrator determines in its sole and absolute discretion that the amendment, suspension, termination, or modification: (a) is required or
advisable in order for the Company, the Plan, or the Award to satisfy Applicable Law, to meet the requirements of any accounting standard or to avoid any adverse accounting treatment, or (b) in connection with any transaction or event described
in Section 11, is in the best interests of the Company or its stockholders. The Administrator may, but need not, take the tax consequences to affected Participants into consideration in acting under the preceding sentence. Termination of this
Plan shall not affect the Administrator’s ability to exercise the powers granted to it under this Plan with respect to Awards granted before the termination or Award Shares issued under such Awards even if those Award Shares are issued after
the termination. 
  

	17.	Reserved Rights 

 17.1 Nonexclusivity of this
Plan. This Plan shall not limit the power of the Company or any Affiliate to adopt other incentive arrangements including, for example, the grant or issuance of stock options, stock, or other equity-based rights under other plans or
independently of any plan. 
 17.2 Unfunded Plan. This Plan shall be unfunded. Although bookkeeping accounts may be established with
respect to Participants, any such accounts will be used merely as a convenience. The Company shall not be required to segregate any assets on account of this Plan, the grant of Awards, or the issuance of Award Shares. The Company and the
Administrator shall not be deemed to be a trustee of stock or cash to be awarded under this Plan. Any obligations of the Company to any Participant shall be based solely upon contracts entered into under this Plan, such as Award Agreements. No such
obligation shall be deemed to be secured by any pledge or other encumbrance on any assets of the Company. Neither the Company nor the Administrator shall be required to give any security or bond for the performance of any such obligation.

  

	18.	Special Arrangements Regarding Award Shares 

 18.1
Escrows and Pledges. To enforce any restrictions on Award Shares including restrictions related to Reverse Vesting, the Administrator may require their holder to deposit the certificates representing Award Shares, with stock powers or other
transfer instruments approved by the Administrator endorsed in blank, with the Company or an agent of the Company to hold in escrow until the restrictions have lapsed or terminated. The Administrator may also cause a legend or legends referencing
the restrictions to be placed on the certificates. 
 18.2 Repurchase Rights 
 (a) Reverse Vesting. If an Option is subject to Reverse Vesting, the Company shall have the right, during the seven months after the
Optionee’s Termination, to repurchase any or all of the Option Shares that were unvested as of the date of that Termination, for a price equal to the lower of: (i) the Option Price for such Shares, minus the amount of any cash dividends
paid or payable with respect to the Option Shares for which the record date precedes the repurchase, and (ii) the Fair Market Value of those Option Shares as of the date of the Termination. The repurchase price shall be paid in (i) cash,
(ii) if the Option Shares were purchased in whole or in part for a promissory note, cancellation of indebtedness under that note, (iii) cancellation of any indebtedness owed by the Optionee to the Company or any Affiliate, or (iv) a
combination of those means. The Company may assign this right of repurchase. 
 (b) Procedure. The Company or its assignee may
choose to give the Optionee a written notice of exercise of its repurchase rights under this Section 18.2. However, the Company’s failure to give such a notice shall not affect its rights to repurchase Option Shares. The Company must,
however, tender the repurchase price during the period specified in this Section 18.2 for exercising its repurchase rights in order to exercise such rights. 
  

 18 

	19.	Beneficiaries 

 A Participant may file a written
designation of one or more beneficiaries who are to receive the Participant’s rights under the Participant’s Awards after the Participant’s death. A Participant may change such a designation at any time by written notice. If a
Participant designates a beneficiary, the beneficiary may exercise the Participant’s Awards after the Participant’s death. If a Participant dies when the Participant has no living beneficiary designated under this Plan, the Company shall
allow the executor or administrator of the Participant’s estate to exercise the Award or, if there is none, the person entitled to exercise the Award under the Participant’s will or the laws of descent and distribution. In any case, no
Option may be exercised after its Expiration Date. 
  

	20.	Miscellaneous 

 20.1 Governing Law. This Plan
and all determinations made and actions taken under this Plan shall be governed by the substantive laws, but not the choice of law rules, of the State of Delaware. 
 20.2 Determination of Value. Fair Market Value shall be determined as follows: 
 (a) Listed
Stock. If the Shares are traded on any established stock exchange or quoted on a national market system, Fair Market Value shall be the closing sales price for the Shares as quoted on that stock exchange or system for the date the value is
to be determined (the “Value Date”) as reported in The Wall Street Journal or a similar publication. If no sales are reported as having occurred on the Value Date, Fair Market Value shall be that closing sales price
for the last preceding trading day on which sales of Shares are reported as having occurred. If no sales are reported as having occurred during the five trading days before the Value Date, Fair Market Value shall be the closing bid for Shares on the
Value Date. If Shares are listed on multiple exchanges or systems, Fair Market Value shall be based on sales or bids on the primary exchange or system on which Shares are traded or quoted. 
 (b) Stock Quoted by Securities Dealer. If Shares are regularly quoted by a recognized securities dealer but selling prices are not reported
on any established stock exchange or quoted on a national market system, Fair Market Value shall be the mean between the high bid and low asked prices on the Value Date. If no prices are quoted for the Value Date, Fair Market Value shall be the mean
between the high bid and low asked prices on the last preceding trading day on which any bid and asked prices were quoted. 
 (c) No
Established Market. If Shares are not traded on any established stock exchange or quoted on a national market system and are not quoted by a recognized securities dealer, the Administrator (following guidelines established by the Board or
Committee) will determine Fair Market Value in good faith. The Administrator will consider the following factors, and any others it considers significant, in determining Fair Market Value: (i) the price at which other securities of the Company
have been issued to purchasers other than Employees, Directors, or Consultants, (ii) the Company’s net worth, prospective earning power, dividend-paying capacity, and non-operating assets, if any, and (iii) any other relevant factors,
including the economic outlook for the Company and the Company’s industry, the Company’s position in that industry, the Company’s goodwill and other intellectual property, and the values of securities of other businesses in the same
industry. 
 20.3 Reservation of Shares. During the term of this Plan, the Company will at all times reserve and keep available such
number of Shares as are still issuable under this Plan. 
  

 19 

 20.4 Electronic Communications. Any Award Agreement, notice of exercise of an Award, or other
document required or permitted by this Plan may be delivered in writing or, to the extent determined by the Administrator, electronically. Signatures may also be electronic if permitted by the Administrator. 
 20.5 Notices. Unless the Administrator specifies otherwise, any notice to the Company under any Award Agreement or with respect to any Awards or
Award Shares shall be in writing (or, if so authorized by Section 20.4, communicated electronically), shall be addressed to the Secretary of the Company, and shall only be effective when received by the Secretary of the Company.

	D.	In the event of any merger or consolidation or other reorganization ‘in which the Company shall be the surviving entity and its stockholders have a right to receive securities

upon such event unless and to the extent the Board of Directors shall have provided for the substitution of other Awards for, or for the assumption by the surviving corporation (or its Parent) of any unexercised, unvested or unsettled Awards then
outstanding. Such action by the Board of Directors may be taken with respect to ISO’s only to the extent permitted by the Code, including Sections 422 and 424. Except to the extent the Board of Directors shall have provided for the substitution
of other Awards for, or for the assumption by another corporation of, any unexercised, unvested or unsettled Awards then outstanding or shall have specifically otherwise provided as permitted by this Subparagraph E, the Awards which have not vested
shall not become exercisable or settleable upon such event and all outstanding Awards shall expire upon such event.

property to which such holder of the Award would have been entitled to receive pursuant to the terms of the merger or consolidation or other reorganization if, at the time of such merger or consolidation or other reorganization, such holder of the

reorganizations.

	A.	Price and Payment. The purchase price of each Share covered by each Option as determined by the Committee. The purchase price of each Share covered by an ISO shall not be
less than the fair market value of a Share at the time of the granting of the Option. The purchase price of each Share covered by NQSO may be less than or more than the fair market value of a Share at the time of the granting of the Option. The
purchase price of the Shares to which an Option shall be exercised shall be paid in full at the time of the exercise in cash or by check, subject to collection. With respect to Options granted to Employees of the Company, the Committee may also
provide that the purchase price may be paid in whole or in part by assigning to the Company a number of Shares having a fair market value, determined as of the date the Option is exercised, equal to the amount of the purchase price for the Shares
being acquired upon the exercise of the Option which the Committee permits to be paid by the assigning of Shares to the Company. In such event, the Committee may, in its sole discretion, require certain representations and other conditions precedent
to the acceptance of the Shares from the Optionee. 

  

	B.	Duration. The duration of the Options shall be as determined by the Committee, but in no event shall an Option granted hereunder be exercisable after the earliest of any of
the following dates: (i) the expiration of ten (10) years from the date the Option is granted; (ii) one (1) year after the cessation of employment of the holder of the Option with the Company, any Subsidiary, or the Parent,
except in the event of termination of such employment by reason of disability, death or retirement; (iii) two (2) years after the cessation of such employment in the event of termination of employment due to death, disability (within in
the meaning of Subsection 422(c)(6) of the Code) or retirement. The Committee’s determination as to whether such employment of an Optionee has ceased and the effective date thereof shall be final and conclusive on all persons affected thereby.
Whether military or other government or eleemosynary service or other leave of absence will constitute termination of such employment shall be determined in each case by the Committee in its sole discretion. 

  

	C.	Non-transferability. ISO’s granted under the Plan shall not be transferable otherwise than by will or the laws of descent and distribution or as otherwise permitted
pursuant to the Code. ISOs may be exercised during the lifetime of the Optionee only by the Optionee personally or by the Optionee’s legal representative. 

  

	D.	Exercise of Option. Options granted hereunder shall be exercisable in whole or in part as determined by the Committee.

Shares shall comply with (or be exempt from) all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, any applicable state securities law, and the
requirements of any stock exchange or nation market system on which the Shares may then be listed. If the issuance or transfer of Shares to be issued or issued pursuant to any Option granted under the Plan may in the opinion of counsel to the
Company conflict or be inconsistent with or not be permitted under any applicable law or regulation of any governmental agency having jurisdiction, including, without limitation, regulations promulgated pursuant to federal and state securities laws,
the Company reserves the right to delay the issuance of the Shares upon the exercise of an Option and such delay shall be without liability to or other obligation of

exemption under any federal or state law with respect to the grant of an Option or the issuance of Shares upon the exercise of an Option or the transfer of such Shares at any time thereafter. The Board of Directors or Committee may require that the
holder of an Option, as a condition to each exercise of the Option in whole or in part to represent to the Company in writing that the Shares to be acquired upon the exercise of the Option are to be acquired by the holder of the Option for
investment purposes only, for such person’s own account, and not with a view to distribution and make such other representations as counsel to the Company may reasonably request to assure the availability of an exemption from or compliance with
the registration, notice, reporting or permitting requirements of applicable federal or state securities laws. The Option may also set forth such other terms and conditions relating to the non registration or qualification of the Shares or the
issuance of the Shares by the Company or the transfer of the Shares by the Optionee under the federal and state securities laws, as the Board of Directors or Committee may prescribe. Such representations and other terms and conditions shall continue
in effect long as counsel to the Company may reasonably request. 

  

	F.	Disposition of Shares. In the event the disposition of Shares acquired upon the exercise of any Option is not covered by a then current registration statement under the
Securities Act of 1933, as amended, and under applicable state securities laws, the Shares so purchased shall be restricted against transfer to the extent and for as long as required by such laws and regulations promulgated thereunder or until, and
as long as, the Shares are covered by applicable registration statements filed by the Company in its sole discretion. 

  

	G.	Tax Withholdings. In any case where the Company, any Subsidiary or the Parent is obliged to account for (i) any tax (or similar liabilities) in any jurisdiction, and/or
(ii) employee and/or employer social security contributions (or similar liabilities) in any jurisdiction, by virtue of the exercise, release or assignment of the Option acquisition and holding of Shares (together, the “Tax
Liability”), the Company, Subsidiary or the Parent as the case may be, may recover the Tax Liability from the Optionee manner as the Board of Directors shall think fit and (without prejudice to the generality of the foregoing) Shares shall not
be transferred to the Optionee unless the Optionee either (iii) made a payment to the Company, Subsidiary or the Parent, as the case may be, of an amount equal to the estimated Tax Liability or (iv) entered into arrangements the Company,
Subsidiary or the Parent, as the case may be, to secure that such a payment is made. 

  

	H.	National Insurance Contributions Joint Election. Without prejudice to the generality of clause VI above (Conditions to Exercise of Options), the Optionees who are subject to
the laws of the United Kingdom may not exercise, release or assign an Option granted under the Plan in any circumstances unless and until the Board of Directors is satisfied that the Optionee has entered into a binding election in the form
prescribed by the Company pursuant to which the Optionee assumes liability for the whole of the employers’ National Insurance contributions in respect of share option gains arising from the Option. 

  

	I.	Executive Officers. In the event any class of equity security of the Company is registered pursuant to Section 12 of the 34 Act, any election granted to an executive
officer (as defined pursuant to rules promulgated under the 1934 Act) of the Parent shall only be made during the period set forth in Rule 16b-3 promulgated under the 1934 Act (or any successor rule or regulation), if any. 

 

					
	Stock Option Plan	 	8	 	

	VII.	EXERCISE. 

 An Option granted hereunder shall be
exercisable in whole or in part only by written notice delivered in person or by mail to the President of the Company or such other officer designated by the President, at its principal executive office, specifying the number of Shares to be
purchased and accompanied by payment therefor and other consideration in accordance with the Option. The holder of an Option shall not be deemed to be a holder of any Shares subject to any Option and shall not be entitled to the rights of a holder
of any Shares, including the right to vote the Shares and to receive dividends, unless and until such Shares have been issued. 
  

	VIII.	STOCK GRANTS AND STOCK UNIT AWARDS. 

 Each Stock
Award Agreement reflecting the issuance of a Stock Grant or Stock Unit shall be in such form and shall contain such terms and conditions as the Committee shall deem appropriate. The terms and conditions of such agreements may change from time to

provisions: 
  

	A.	Consideration. A Stock Grant or Stock Unit may be awarded in consideration for such property or services as is permitted under applicable law, including for past services
actually rendered to the Company or a Parent or Subsidiary for its benefit.

forfeiture restriction or other conditions in favor of the Company in accordance with a vesting or lapse schedule to be determined by the Committee. 

  

	C.	Termination. In the event of a Participant’s termination of employment for any reason, the Company may reacquire any or all of the Shares held by the Participant which
have not vested or which are otherwise subject to forfeiture or other conditions as of the date of termination of employment under the terms of the Stock Award Agreement. 

  

	D.	Transferability. Except as determined by the Board of Directors and reflected in the Stock Award Agreement, no rights to acquire Shares under a Stock Grant or a Stock Unit
shall be assignable or otherwise transferable by the Participant except by will or by the laws of descent and distribution. 

  

	IX.	STOCK APPRECIATION RIGHTS. 

  

	A.	In General. Stock Appreciation Rights may be granted either alone, in addition to, or in tandem with other Awards granted under the Plan. The Committee may grant Stock
Appreciation Rights to eligible Participants subject to terms and conditions not inconsistent with the Plan and determined by the Committee. The specific terms and conditions applicable to the Participant shall be provided for in the Stock Award
Agreement. Stock Appreciation Rights shall be exercisable, in whole or in part, at such times as the Committee shall specify in the Stock Award Agreement. 

  

					
	Stock Option Plan	 	9	 	

	B.	Exercise of Stock Appreciation Right. Upon the exercise of a Stock Appreciation Right, in whole or in part, the Participant shall be entitled to a payment in an amount
equal to the excess of the fair market value, as determined by the Committee, on the date of exercise of a fixed number of Shares covered by the exercised portion of the Stock Appreciation Right, over the fair market value, as determined by the
Committee, on the grant date of the Shares covered by the exercised portion of the Stock Appreciation Right (or if reflected in the Stock Award Agreement, such other amount calculated with respect to Shares subject to the award as the Committee may
determine). The amount due to the Participant upon the exercise of a Stock Appreciation Right shall be paid in such form of consideration as determined by the Committee and may be in cash, Shares or a combination thereof, over the period or periods
specified in the Stock Award Agreement. A Stock Award Agreement may place limits on the amount that may be paid over any specified period or periods upon the exercise of a Stock Appreciation Right, on an aggregate basis or as to any Participant. A
Stock Appreciation Right shall be considered exercised when the Company receives written notice of exercise in accordance with the terms of the Stock Award Agreement from the person entitled to exercise the Stock Appreciation Right.

  

	C.	Transferability. Except as determined by the Board of Directors and reflected in the Stock Award Agreement, no Stock Appreciation Rights shall be assignable or otherwise
transferable by the Participant except by will or by the laws of descent and distribution. 

  

	X.	SECTION 162(m) COMPLIANCE. 

 Any Stock Award (other
than an Option or any other Stock Award having a purchase price equal to 100% of the fair market value of the Shares, as determined by the Committee, on the date such Award is made) that is intended as “qualified performance-based
compensation” within the meaning of Section 162(m) of the Code must vest or become exercisable contingent on the achievement of one or more Qualifying Performance Criteria. Notwithstanding anything to the contrary herein, the Committee
shall have the discretion to determine the time and manner of compliance with Section 162(m) of the Code as required under applicable regulations and to conform the procedures related to the Award to the requirements of Section 162(m) of
the Code and may reduce the number of Shares granted or amount of cash or other property to which a Participant may otherwise have been entitled with respect to an Award designed to qualify as performance-based compensation under Section 162(m)
of the Code. 
  

	XI.	TERMINATION AND AMENDMENT. 

 The Board of Directors
may at any time terminate the Plan, or make such amendments thereto or modifications thereof as it shall deem advisable, including amendments deemed necessary or desirable to conform any ISO to any change in the Code or regulations thereto provided,
however, that the Board of Directors may not, without further approval by the stockholders of the Company, increase the maximum number of Shares for which Awards may be granted under the Plan or change the designation of the class of employees and
other persons eligible to receive Awards. In addition, unless approved by the stockholders of the Company, no 

  

					
	Stock Option Plan	 	10	 	

 
amendment shall be made that would result in a repricing of Options by (x) reducing the exercise price of outstanding Options or (y) canceling an
outstanding Option held by a Participant and re-granting to the Participant a new Option with a lower exercise price, in either case other pursuant to Paragraph V.B. of the Plan. No termination, modification or amendment of the Plan shall, without
the consent of the Participant to whom an Award shall theretofore have been granted adversely affect the rights of such Participant under such Award without the written consent of such Participant. 
  

	XII.	MISCELLANEOUS. 

  

	A.	Applicable Law. The Plan shall be governed and construed in accordance with the laws of the State of Delaware. 

  

	B.	Employee/Employer Rights. The granting of Awards hereunder shall be entirely discretionary and nothing in the Plan shall be deemed to give any person any right of continued
employment or give any person any right to receive Awards or additional Awards hereunder or interfere in any way with the right of the Company, its Parent or Subsidiary to terminate the Participant’s employment for any reason or the right of
the Participant to terminate his/her employment for any reason. Without prejudice to the generality of the foregoing, participation in this Plan is a matter entirely separate from any pension right or entitlement a Participant may have and from
their terms and conditions of employment and in particular (but without limiting the generality of the foregoing) any individual who leaves the employment of the Company or its Subsidiaries, or the Parent or who otherwise ceases to be an employee
shall not be entitled to any compensation for any loss of any right or benefit or prospective or benefit under the Plan which the Participant might otherwise have enjoyed whether such compensation is claimed by way of damages for wrongful dismissal
or other breach of contract or by way of compensation for loss of office, employment or otherwise howsoever. 

  

	C.	ISO Grants. The Plan is intended to provide in part for the grant of ISO’s pursuant to Section 422 of the Code, including amendments thereto hereafter adopted, and
the provisions of the Plan as they relate to ISO’s and the ISO’s granted shall be construed to effectuate such purpose. If for any reason it is subsequently determined that an intended to qualify as an ISO does not so qualify, the Company,
Parent and Subsidiary shall have no liability to the Participant and such Options shall be deemed to be Non-Qualified Stock Options. 

  

	XIII.	EFFECTIVE DATE. 

 The Plan shall become effective on
the date of its adoption by the Board of Directors subject to the approval of the Plan by the stockholders of the Company within twelve (12) months after the date of its adoption. The date of granting of an Award shall be the date on which the
Committee makes the determination of granting such Award or such later date as designated by the Committee.
