 4. Exercise of the Option. 
 4.1 Right to Exercise. Except as otherwise provided
herein, the Option shall be exercisable on and after the Initial Exercise Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option. In no event shall the Option be exercisable for more shares than the Number of Option Shares. 
 4.2 Method of Exercise. Exercise of the Option shall be by written notice to the Company which must state the election to exercise the Option, the number of whole shares of Stock for which the Option is
being exercised and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. The written notice must be signed by the

 4 








 full payment of the aggregate Exercise Price for the number of shares of Stock being purchased. The Option shall be
deemed to be exercised upon receipt by the Company of such written notice and the aggregate Exercise Price.

for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company of whole shares of Stock owned by the Optionee having a Fair Market Value not
less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as defined in Section 4.3(c), or (iv) by any combination of the foregoing. 
 (b) Tender of Stock. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of shares of Stock to the extent such tender of Stock would constitute a violation of the provisions
of any law, regulation or agreement restricting the redemption of the Company’s stock. The Option may not be exercised by tender to the Company of shares of Stock unless such shares either have been owned by the Optionee for more than six
(6) months or were not acquired, directly or indirectly, from the Company. 
 (c) Cashless Exercise. A “Cashless
Exercise” means the assignment in a form acceptable to the Company of the proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option pursuant to a program or procedure approved by
the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company reserves, at any and all times,
the right, in the Company’s sole and absolute discretion, to decline to approve or terminate any such program or procedure. 
 4.4
Tax Withholding. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Optionee agrees to make adequate provision for any sums required to satisfy the federal, state, local
and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option,
(ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option, or (iii) the lapsing of any restriction with respect to any shares acquired upon exercise of the Option. 
 4.5 Certificate Registration. Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the
shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee. 
 4.6 Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise 
  

 5 








 would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or
the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the
Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an
applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE
OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and
sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the
Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be
requested by the Company. 
 4.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the
exercise of the Option. 
 5. Nontransferability of the Option. The Option may be exercised during the lifetime of the Optionee
only by the Optionee or the Optionee’s guardian or legal representative and may not be assigned or transferred in any manner except by will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the
extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution. 
 6. Termination of the Option. The Option shall terminate and may no longer be exercised on the first to occur of (a) the Option
Expiration Date, (b) the last date for exercising the Option following termination of the Optionee’s Service as described in Section 7, or (c) a Change in Control to the extent provided in Section 8. 
 7. Effect of Termination of Service. 
 7.1 Option Exercisability. 
 (a) Disability. If the Optionee’s Service with the Participating Company
Group is terminated because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or
legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 
  

 6 








 (b) Death. If the Optionee’s Service with the Participating Company Group is terminated
because of the death of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the
right to exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration
Date. The Optionee’s Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee’s termination of Service. 
 (c) Other Termination of Service. If the Optionee’s Service with the Participating Company Group terminates for any reason, except
Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee within three (3) months after the date on which the
Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 
 7.2 Extension if Exercise Prevented
by Law. Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until three
(3) months after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date. 
 7.3 Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a sale, within the applicable time periods set forth in Section 7.1, of shares acquired upon the exercise
of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by
the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee’s termination of Service, or (iii) the Option Expiration Date. 
 8. Ownership Change and Change in Control. 
 8.1 Definitions. 
 (a) An “Ownership Change Event” shall be deemed to have
occurred if any of the following occurs with respect to the Company: 
 (i) the direct or indirect sale or exchange in a single or series of
related transactions by the shareholders of the Company of more than fifty percent (50%) of the voting stock of the Company; 
 (ii) a
merger or consolidation in which the Company is a party; 
 (iii) the sale, exchange, or transfer of all or substantially all of the assets
of the Company; or 
  

 7 








 (iv) a liquidation or dissolution of the Company. 
 (b) A “Change in Control” shall mean an Ownership Change Event or a series of related Ownership Change Events (collectively, the
“Transaction”) wherein the shareholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the same proportions as their ownership of shares of the Company’s
voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the “Transferee Corporation(s)”), as the case may be. For purposes of the preceding sentence, indirect beneficial ownership shall include, without limitation, an interest resulting
from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board
shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company or multiple Ownership Change Events are related, and its determination shall be final, binding and conclusive. 
 8.2 Effect of Change in Control on Option. In the event of a Change in Control, any unexercised portion of the Option shall be immediately
exercisable and vested in full as of the date ten (10) days prior to the date of the Change in Control. Any exercise of the Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the
Change in Control. In addition, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the “Acquiring Corporation”), may either assume the Company’s rights and
obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation’s stock. The Option shall terminate and cease to be outstanding effective as of the date of the Change in Control to the
extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of
the Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as otherwise provided
herein. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the Option immediately prior to an Ownership Change Event described in Section 8.1(a)(i) constituting a Change in Control is the surviving
or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an
affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the Option shall not terminate. 
 9. Adjustments for Changes in Capital Structure. In the event of any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise Price and class of shares of stock subject to the Option. If a majority of the shares which are
of the same class as the shares that are subject to the Option are exchanged for, 
  

 8 








 converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation
(the “New Shares”), the Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares and the Exercise Price shall be adjusted in a
fair and equitable manner, as determined by the Board, in its sole discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be rounded down to the nearest whole number, and in
no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. 
 10.
Rights as a Shareholder. The Optionee shall have no rights as a shareholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as
evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such
certificate is issued, except as provided in Section 9. 
 11. Legends. The Company may at any time place legends
referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present
to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry out the provisions of this Section. 
 12. Binding Effect. Subject to the restrictions on transfer set forth herein, this Option Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. 
 13. Termination or
Amendment. The Board may terminate or amend the Plan or the Option at any time; provided, however, that no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee
unless such termination or amendment is necessary to comply with any applicable law, regulation or rule. No amendment or addition to this Option Agreement shall be effective unless in writing. 
 14. Integrated Agreement. This Option Agreement constitutes the entire understanding and agreement of the Optionee and the Participating
Company Group with respect to the subject matter contained herein, and there are no agreements, understandings, restrictions, representations, or warranties among the Optionee and the Participating Company Group with respect to such subject matter
other than those as set forth or provided for herein. To the extent contemplated herein, the provisions of this Option Agreement shall survive any exercise of the Option and shall remain in full force and effect. 
 15. Applicable Law. This Option Agreement shall be governed by the laws of the State of Delaware as such laws are applied to agreements
between Delaware residents entered into and to be performed entirely within the State of Delaware.
