(a)    In General.

An electronic Exercise Notice must be digitally signed or authenticated by Participant in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that Participant is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile or electronic transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company). Each Exercise Notice, whether electronic or written, must state Participant’s election to exercise the Option, the number of whole shares of Common Stock for which the Option is being exercised and such other representation and agreements as to Participant’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate Exercise Price for the number of shares of Common Stock being purchased in such form of consideration under Section 4.3(a) and the payment of any applicable withholding tax in accordance with Section 4.4. The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice, the aggregate Exercise Price and any applicable withholding tax.

(a)    Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Common Stock for which the Option is being exercised shall be made in one of the following forms:

        (i)     By cash, check, bank draft or money order payable to the Company;

(ii)     With the consent of the Committee, by tender to the Company, or attestation to the ownership, of whole shares of Common Stock owned by Participant having a Fair Market Value not less than the aggregate Exercise Price;

(iii)     With the consent of the Committee, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of Shares with a Fair Market Value that does not exceed the aggregate Exercise Price; provided, however, that the Company will accept a cash or other payment from Participant to the extent of any remaining balance of the aggregate Exercise Price not satisfied by such reduction in the number of whole Shares to be issued;

(iv)     By means of a Cashless Exercise, as defined in Section 4.3(b); or

(v)     By any combination of the foregoing.

(b)    Limitations on Forms of Consideration.

(i)    Tender of Stock. Notwithstanding the foregoing, the Option may not be exercised (and any tax withholding obligation may not be satisfied) by tender to the Company, or attestation to the ownership, of shares of Common Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. If required by the Company, the Option may not be exercised (and any tax withholding obligation may not be satisfied) by tender to the Company, or attestation to the ownership, of shares of Common Stock unless such shares either have been owned by Participant for more than six (6) months or such other shorter or longer period, if any, required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company.

(ii)    Cashless Exercise. A “Cashless Exercise” means the delivery of a properly executed notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale with respect to some or all of the shares of Common Stock then issuable upon 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), and confirmation that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the Option Exercise Price; provided that payment of such proceeds is then made to the Company at such time as may be required by the Committee, but in any event not later than the settlement of such sale. The Company reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to establish, decline to approve or terminate any such program or procedure, including with respect to Participant notwithstanding that such program or procedures may be available to others.

(a)    Tax Withholding Right. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company or an Affiliate (each, a “Participating Company” and together the “Participating Company Group”), Participant hereby authorizes withholding from payroll and any other amounts payable to Participant, and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), 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. The Company shall

have no obligation to deliver shares of Common Stock until the tax withholding obligations of the Participating Company Group have been satisfied by Participant.

(b)    Forms of Consideration Authorized. The Company and its Affiliates may withhold or Participant may make such payment in one or more of the forms specified below:

(i)    By cash, check, bank draft or money order payable to the Company or its Affiliate with respect to which the withholding obligation arises;

(ii)    By the deduction of such amount from other compensation payable to Participant;

(iii)    With respect to any withholding taxes arising in connection with the exercise of the Option, with the consent of the Committee, by tendering to the Company, or attestation to the ownership, of whole shares of Common Stock owned by Participant having a Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of the Company and its Affiliates based on the minimum applicable statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes (or such lesser amount as may be necessary to avoid classification of the Option as a liability for financial accounting purposes);

(iv)     With the consent of the Committee, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of Shares with a Fair Market Value not exceeding the amount necessary to satisfy the withholding obligation of the Company and its Affiliates based on the minimum applicable statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes (or such lesser amount as may be necessary to avoid classification of the Option as a liability for financial accounting purposes); provided, however, that the Company will accept a cash or other payment from Participant to the extent of any remaining balance of the tax withholding obligation is not satisfied by such reduction in the number of whole Shares to be issued;

(v)    With respect to any withholding taxes arising in connection with the exercise of the Option, by means of a Cashless Exercise pursuant to which the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company or the Affiliate with respect to which the withholding obligation arises in satisfaction of such withholding taxes; or

(vi)    In any combination of the foregoing.

(c)    Certain Company Rights. With respect to any withholding taxes arising in connection with the Option, in the event Participant fails to provide timely payment of all sums required pursuant to Section 0, the Company shall have the right and option, but not the obligation, to treat such failure as an election by Participant to satisfy all or any portion of Participant’s required payment obligation pursuant to Section 0 or Section Error! Reference source not found. above, or any combination of the foregoing as the Company may determine to be appropriate.

(d)    Participant Responsibility. Participant is ultimately liable and responsible for all taxes owed in connection with the Option, regardless of any action the Participating Company Group takes with respect to any tax withholding obligations that arise in connection with the Option. No member of the Participating Company Group makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or exercise of the Option or the

subsequent sale of Common Stock. The Participating Company Group does not commit and is under no obligation to structure the Option to reduce or eliminate Participant’s tax liability.

4.5    Beneficial Ownership of Shares; Certificate Registration. Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of Participant with any broker with which Participant has an account relationship of which the Company has notice any or all shares acquired by Participant pursuant to the exercise of the Option. Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of Participant, or, if applicable, in the names of the heirs of Participant.

4.6    Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares of Common 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 Common Stock upon exercise 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 Common Stock may then be listed. In addition, the Option may not be exercised unless (a) 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 (b) 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. PARTICIPANT IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, PARTICIPANT 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 Participant 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.

During the lifetime of Participant, the Option shall be exercisable only by Participant or Participant’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of Participant or Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of Participant, the Option, to the extent provided in Section 7, may be exercised by Participant’s legal representative or by any person empowered to do so under the deceased Participant’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 after the first to occur of (a) the close of business on the Option Expiration Date, or (b) the close of business on the last date for exercising the Option following termination of Participant’s Continuous Service as described in Section 7.

7.    Effect of Termination of Continuous Service.

7.1    Option Exercisability. The Option shall terminate immediately upon Participant’s termination of Continuous Service to the extent that it is then unvested and shall be exercisable after Participant’s termination of Continuous Service to the extent unexercised and exercisable for Vested Shares only during the applicable time period as determined below and thereafter shall terminate.

(a)    Disability. If Participant’s Continuous Service terminates because of the Disability of Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which Participant’s Continuous Service terminated, may be exercised by Participant (or Participant’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which Participant’s Continuous Service terminated, but in any event no later than the Option Expiration Date; provided, however, that, subject to Section 10 of the Plan and the last paragraph under the heading “Vested Shares” in the Notice, if Participant’s termination of Continuous Service due to the Disability of Participant occurs prior to the Amendment Approval Date, any portion of the Option which is vested at the time of termination of Participant’s Continous Service shall remain exercisable until the later of (i) the date that is three (3) months following the Amendment Approval Date (provided the Amendment Approval Date occurs on or prior to August 27, 2027) or (ii) the date that is twelve (12) months after the date on which Participant’s Continuous Service terminated.

Participant’s Continuous Service shall be deemed to have terminated on account of death if Participant dies within three (3) months after Participant’s termination of Continuous Service for any reason other than the discharge of Participant by a Participating Company for Cause.

(c)    Cause. If Participant’s Continuous Service terminates because of the discharge of Participant by a Participating Company for Cause, the Option shall terminate immediately upon such termination and may not thereafter by exercised by Participant.    

(d)    Other Termination of Continous Service.

(e)    Amendment Approval Condition to Exercise. Notwithstanding the foregoing, to the extent the Amendment Approval Date does not occur on or prior to August 27, 2018, this Option shall be canceled and become null and void, regardless of any earlier termination of Participant’s Continuous Service.
