 ARTICLE IV. 
 PURCHASE OF SHARES 
  

	 	4.1	Option Price 

 The Option
Price per share of the Class A Common Stock sold to Participants hereunder shall be 85% of the Fair Market Value of such share on the Offering Date. 
  

	 	4.2	Purchase of Shares 


(a) On each Offering Date on which he or she is employed, each Participant will automatically and without any action on his or her
part be deemed to have exercised his or her option to purchase at the Option Price the largest number of whole shares of Class A Common Stock which can be purchased with the amount in the Participant’s Plan Account. The balance, if any,
remaining in the Participant’s Plan Account (after exercise of his or her option) as of an Offering Date shall, at the election of the Company, be either carried forward to the next Option Period or refunded. 

(b) As soon as practicable following each Offering Date, the Company, pursuant to each Participant’s instructions, will
electronically deliver to the Participant’s designated brokerage account such number of shares purchased pursuant to Section 4.2(a) above. Thereafter, if requested by the Participant, the Company will physically deliver to the Participant
a certificate issued in his or her name for such number of shares; or transfer such shares to another brokerage account. In the event the Company is required to obtain from any commission or agency authority to issue and deliver the shares, either
physically or electronically, the Company will seek to obtain such authority. Inability of the Company to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance and delivery of the
shares, either physical or electronic, shall relieve the Company from liability to any Participant except to refund to him or her the amount withheld. 
  

	 	4.3	Limitations on Purchase 


No Employee shall be granted an option under the Plan which permits his or her rights to purchase Class A Common Stock under the
Plan or any other employee stock purchase plan of the Company or any of its Subsidiaries to accrue at a rate which exceeds $25,000 (as measured by the Fair Market Value of such Class A Common Stock at the time the option is granted) for each
calendar year such option is outstanding. 
  

	 	4.4	Transferability of Rights 


An option granted under the Plan shall not be transferable and is exercisable only by the Participant. No option or interest or right
therein or part thereof shall be liable for the debts, contracts or engagements of the Participant or his or her successors in interest or shall be subject to disposition by alienation, anticipation, pledge, encumbrance, assignment or any other
means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempt at disposition thereof shall be null and
void and of no effect.

	 	5.4	Insufficient Shares 

 If
the aggregate funds available for the purchase of Class A Common Stock on any Offering Date would cause an issuance of shares in excess of the number provided for in Section 5.1 hereof, (a) the Committee shall proportionately reduce
the number of shares that would otherwise be purchased by each Participant in order to eliminate such excess, and (b) the Plan shall automatically terminate immediately after such Offering Date. 

 

	 	5.5	Rights as Stockholders 


With respect to shares of Class A Common Stock subject to an option, a Participant shall not be deemed to be a stockholder and shall

following exercise of his or her option. 
 ARTICLE VI. 

TERMINATION OF PARTICIPATION 
  

	 	6.1	Early Termination of Participation; Voluntary Withdrawal 

 (a) A Participant may terminate his or her obligation to make any additional payments into the Plan, either by additional payroll deductions or by additional lump sum payments, at any time during an

Upon any such early termination, such Participant may elect either to withdraw from the Plan pursuant to Section 6.1(b) below or to have amounts credited to his or her Plan Account held in the Plan for the purchase of Class A Common Stock

such Option Period.

automatically terminated: (i) the Participant’s payroll deduction authorization or written notice of election to participate in the Plan by remitting a lump sum payment, as applicable, (ii) his or her interest in the Plan and
(iii) his or her option under the Plan. Any Eligible Employee who withdraws from the Plan may again become a Participant in accordance with Section 3.2 hereof. 

 

	 	6.2	Termination of Eligibility 

 (a) If a Participant ceases to be eligible under Section 3.1 hereof for any reason, the amount in such Participant’s Plan Account will be refunded to the Participant or his or her

(b) Upon payment by the Company to the Participant or his or her beneficiary or estate of the remaining balance, if any, in
Participant’s Plan Account, the Participant’s interest in the Plan and the Participant’s option under the Plan shall terminate.

 ARTICLE VII. 
 GENERAL PROVISIONS 
  

	 	7.1	Condition of Employment
