Article
8.

Payroll Deductions


 


8.1                
Payroll Deduction Elections. An Eligible Employee who files
an enrollment form pursuant to Article 8 shall elect and authorize in such form to have deductions made from his or her Base Earnings
on each payday he or she receives a paycheck during the Accumulation Period to which the enrollment form relates, and he or she shall
designate on such form the percentage (in whole percentages) of Base Earnings to be deducted each payday during such Accumulation Period.
The minimum an Employee may elect and authorize to have deducted is 1% of his or her Base Earnings paid per pay period in such Accumulation
Period, and the maximum is 15% of his or her Base Earnings paid per pay period in such Accumulation Period (or such larger or smaller
percentage as the Administrator may designate from time to time).


 


8.2                
Duration of Payroll Deductions. Deductions from a Participant’s
Base Earnings shall commence upon the first payday on or after the commencement of the Accumulation Period, and shall continue until the
date on which such authorization ceases to be effective in accordance with Article 6. The amount of each deduction made for a Participant
shall be credited to the Participant’s Account.


 


8.3                
Unfunded Status of Payroll Deductions. Prior to the time
a Participant’s payroll deduction is used to purchase Shares as provided in Article 9 below, such amounts are considered
general assets of the Company or Participating Subsidiary (as applicable) and, as such, are subject to the claims of the Company’s
or Participating Subsidiary’s creditors in the event of insolvency or bankruptcy. The Company or Participating Subsidiary may use
such funds for any corporate purpose, and the Company will not be obligated to segregate such funds from the Company’s or Participating
Subsidiary’s general corporate funds and/or deposit such funds with an independent third party.


 


8.4                
Cancellation of Payroll Deduction Election. As of the last
day of any month during an Accumulation Period, a Participant may elect to cease (but not to increase or decrease) payroll deductions
made on his or her behalf for the remainder of such Accumulation Period by filing the applicable election with the Company or Participating
Subsidiary in such form and manner and at such time as may be permitted by the Administrator. A Participant who has ceased payroll deductions
may have the amount which was credited to his or her Account prior to such cessation applied to the purchase of Shares as of the Purchase
Date in accordance with Section 9.1 and receive the balance of the Account with respect to which the enrollment is ceased, if any,
in cash. A Participant who has ceased payroll deductions may also voluntarily withdraw from the Plan pursuant to Section 10.1.
Any Participant who ceases payroll deductions for an Accumulation Period may re-enroll in the Plan on the next subsequent Enrollment Date
following the cessation in accordance with the provisions of Article 6. A Participant who ceases to be employed by the Company
or any Participating Subsidiary will cease to be a Participant in accordance with Section 10.2.


 


8.5                
No Additional Contributions Permitted. A Participant may
not make any separate or additional contributions to his Account under the Plan. Neither the Company nor any Participating Subsidiary
shall make separate or additional contributions to any Participant’s Account under the Plan.

Article
9.

Purchase of Shares


 


9.1                
Exercise of Options. Subject to Section 9.2, any
option held by the Participant which was granted under this Plan and which remains outstanding as of a Purchase Date shall be deemed to
have been exercised on such Purchase Date for the purchase of the number of whole Shares which the funds accumulated in his or her Account
as of the Purchase Date will purchase at the applicable purchase price. Unless otherwise determined by the Committee, any payroll deductions
which are not sufficient to purchase a whole Share shall be retained in a Participant’s account for the subsequent Accumulation
Period. Any other amounts in a Participant’s Account after a Purchase Date shall be returned to the Participant. 


 


No
Shares will be purchased on behalf of any Participant who fails to file an enrollment form authorizing payroll deductions for an Accumulation
Period.


 


9.2                
Effect of Withdrawal from the Plan. A Participant who holds
an outstanding option as of a Purchase Date shall not be deemed to have exercised such option if the Participant elected not to exercise
the option by withdrawing from the Plan in accordance with Section 10.1.


 


9.3                
Option Exercise Price. The purchase price for each Share
purchased under any option shall not be less than 85% of the lesser of (a) the Fair Market Value of a Share on the Purchase Date or (b)
the Fair Market Value of a Share on the first Trading Day of the Accumulation Period. Notwithstanding the preceding, the Administrator
may establish a different purchase price for each Share purchased under any option provided that such purchase price is determined at
least thirty (30) days prior to the beginning of the Accumulation Period for which it is applicable and is not less than the exercise
price described in the preceding sentence.


 


9.4                
Restrictions on Option Exercise. If the total number of
Shares for which an option is exercised on any Purchase Date in accordance with this Article 9, when aggregated with all Shares
previously granted under this Plan, exceeds the maximum number of Shares reserved in Section 4.1 or pursuant to any aggregate limit
imposed by the Committee pursuant to Section 7.3(b)(ii), the Administrator shall make a pro rata allocation of the Shares available
for delivery and distribution in as nearly a uniform manner as shall be practicable and as it shall determine to be equitable, and the
balance of the cash amount credited to the Account of each Participant under the Plan shall be returned to him or her as promptly as administratively
practical.


 


Article
10.

Withdrawal From the Plan; Termination of Employment; Leave of Absence; Death


 


10.1            
Withdrawal from the Plan. A Participant may withdraw from the Plan in full (but not in part) during any Accumulation
Period by delivering a notice of withdrawal to the Company (in a manner prescribed by the Administrator) at any time prior to the first
day of the calendar last month immediately preceding the Purchase Date for such Accumulation Period, or at such shorter time in advance
of the Purchase Date as the Administrator may permit. If notice of withdrawal is timely received, all funds then accumulated in the Participant’s
Account shall not be used to purchase Shares, but shall instead be distributed to the Participant as soon as administratively practical,
and the Participant’s payroll deductions shall cease as soon as administratively practical. An Employee who has withdrawn during
an Accumulation Period may not return funds to the Company or a Participating Subsidiary during the same Accumulation Period and require
the Company or Participating Subsidiary to apply those funds to the purchase of Shares, nor may such Participant’s payroll deductions
continue, in accordance with Article 6. Any Eligible Employee who has withdrawn from the Plan may, however, re-enroll in the Plan
on the next subsequent Enrollment Date following withdrawal in accordance with the provisions of Article 6.


 






    8 


     


    

 


10.2            
Termination of Employment. Participation in the Plan terminates immediately when a Participant ceases to be employed
by the Company or any Participating Subsidiary for any reason whatsoever, including but not limited to termination of employment, whether
voluntary or involuntary, or on account of disability, or retirement, but not including death, or if the Participating Subsidiary employing
the Participant ceases for any reason to be a Participating Subsidiary. Participation in the Plan also terminates immediately when a Participant
ceases to be an Eligible Employee under Article 5 or withdraws from the Plan. Upon termination of participation such terminated
Participant’s outstanding options shall thereupon terminate. As soon as administratively practicable after termination of participation,
the Company shall pay to the Participant or legal representative all amounts accumulated in the Participant’s Account and held by
the Company at the time of termination of participation, and any Participating Subsidiary shall pay to the Participant or legal representative
all amounts accumulated in the Participant’s Account and held by the Participating Subsidiary at the time of termination of participation.


 


10.3            
Leave of Absence. If a Participant takes an unpaid leave of absence without terminating employment, such Participant
will be deemed to have discontinued contributions to the Plan in accordance with Section 8.3, but will remain a Participant in
the Plan through the balance of the Accumulation Period in which his or her leave of absence begins, so long as such leave of absence
does not exceed ninety (90) days. If a Participant takes an unpaid leave of absence without terminating employment, such Participant will
be deemed to have withdrawn from the Plan in accordance with Section 10.1
on the ninety-first (91st) day of such leave of absence.


 


10.4            
Death. As soon as administratively feasible after the death of a Participant, amounts accumulated in his or her Account
shall be paid in cash to the beneficiary or beneficiaries designated by the Participant on a beneficiary designation form approved by
the Administrator, but if the Participant does not make an effective beneficiary designation then such amounts shall be paid in cash to
the Participant’s spouse if the Participant has a spouse, or, if the Participant does not have a spouse, to the executor, administrator
or other legal representative of the Participant’s estate. Such payment shall relieve the Company and the Participating Subsidiary
of further liability with respect to the Plan on account of the deceased Participant. If more than one beneficiary is designated, each
beneficiary shall receive an equal portion of the Account unless the Participant has given express contrary instructions. None of the
Participant’s beneficiary, spouse, executor, administrator or other legal representative of the Participant’s estate shall,
prior to the death of the Participant by whom he has been designated, acquire any interest in the amounts credited to the Participant’s
Account under the Plan.

through the sale of the Shares acquired on exercise of an option or upon the transfer of Shares, through a broker-dealer to whom the Participant
has submitted an irrevocable instructions to deliver promptly to the Company or the Subsidiary Corporation, the amount to be withheld);
(B) requesting the Company to withhold from those Shares that would otherwise be received upon exercise of the Option or upon the transfer

to be satisfied by withholding Shares upon the transfer of Shares, pursuant to clause (i)(B) above shall not exceed the minimum amount
of taxes, including social security contributions, required to be withheld under federal, state and local law. An election by a Participant
under this subsection is irrevocable. Any fractional share amount and any additional withholding not paid by the withholding or surrender

under employment with the Employing Entity. Any actions undertaken by the Employing Entity or involvement of the Employing Entity in the
administration of the Plan are performed in the name of the Company and/or the Committee and shall not be deemed to establish any claim
against the Employing Entity for performance of the Plan. Thus, the Employing Entity shall not be held liable for proper performance of
the Plan. Irrespective of any information provided or support delivered by the Employing Entity, the Employing Entity does not assume
any obligation in the context of the Plan.

(d)              
Participation in the Plan is granted on an exclusively voluntary basis. Even if there is a repeated grant of rights and
without express notification that the grant is paid voluntarily, no legal claim for future grants exists and further grants remain in
the complete discretion of the Company.

for such processing under Applicable Data Protection Laws and agrees that its participation in the Plan or any other rights hereunder
is subject to the Participant providing and not withdrawing such consent.
