Capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the Agreement.

Notwithstanding anything to the contrary in the Agreement, including in Section 1.1 thereof, the Company and the Purchaser hereby agree that, on the terms and subject to the conditions in the Agreement, on the Closing Date, the Company agrees to sell and issue to the Purchaser, and the Purchaser agrees to purchase from the Company 6,346,155 shares of Class A Common Stock, free and clear of any Liens (other than restrictions arising under applicable securities Laws), at a purchase price of $15.60 per share of Class A Common Stock.   Notwithstanding anything to the contrary in the Agreement, the Company and the Purchaser hereby further agree that, subject only to the satisfaction of the conditions set forth in paragraph five of this letter agreement, on the date that is 5 business days following the receipt by the Purchaser of the approval contemplated by Item 6 of Schedule 2.2(b) to the Agreement (the “Second Closing Date”), the Company agrees to sell and issue to the Purchaser, and the Purchaser agrees to purchase from the Company 1,666,666 shares of Class A Common Stock, free and clear of any Liens (other than restrictions arising under applicable securities Laws), at a purchase price of $15.60 per share of Class A Common Stock (the “Second Purchase Price”).  The closing of the purchase and sale by the Purchaser of the Class A Common Stock referred to in the previous sentence pursuant to this letter agreement (the “Second Closing”) shall be held at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52^nd Street, New York, New York 10019, at 10:00 am New York time on the Second Closing Date.

Notwithstanding anything to the contrary in the Agreement, the Company and the Purchaser hereby agree that, if the Second Closing has not occurred on or before October 6, 2017, (i) neither the Company nor the Purchaser shall be obligated to consummate the Second Closing and (ii) the Company and the Purchaser will discuss in good faith possible alternative investment arrangements.

The parties hereto agree that references in Section 1.2(b) of the Agreement to the Closing and the Closing Date shall be deemed to be references to the Second Closing and the Second Closing Date for purposes of the Second Closing and that references to the Purchase Price in Section 1.2(b)(2) of the Agreement shall be deemed to refer to the pro rata portion of the Purchase Price payable in respect of the number of shares of Class A Common Stock being purchased on the Closing Date or the Second Closing Date, as applicable.
