(a)-(b) By virtue of their relationships, the Reporting Persons may be deemed to constitute a group within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As such, the Reporting Persons may be deemed to beneficially own an aggregate of 1,201,485 shares of Class A Common Stock, which includes (i) 930,596 shares of Class A Common Stock held by SLP Holdco and (ii) 242,889 shares of Class A Common Stock and 28,000 shares of Class A Common Stock underlying call options referenced in Item 6 held by SLP V Marquee, representing in the aggregate approximately 6.3% of the issued and outstanding Class A Common Stock of the Issuer.

• 8,000 shares of Class A Common Stock with an exercise price of $195.00 per share,

• 8,000 shares of Class A Common Stock with an exercise price of $200.00 per share,

• 10,000 shares of Class A Common Stock with an exercise price of $210.00 per share, and

• 2,000 shares of Class A Common Stock with an exercise price of $220.00 per share.

SLP V Marquee sold exchange-traded put options, expiring on March 16, 2018 and which are currently outstanding, that give the holder the right to sell to SLP V Marquee:

• 42,500 shares of Class A Common Stock with an exercise price of $220.00 per share,

• 52,400 shares of Class A Common Stock with an exercise price of $230.00 per share,

• 36,800 shares of Class A Common Stock with an exercise price of $240.00 per share, and

• 10,000 shares of Class A Common Stock with an exercise price of $250.00 per share.

The put options sold by SLP V Marquee do not give any of the Reporting Persons direct or indirect voting, investment or dispositive control over any shares of Class A Common Stock, unless and until exercised by the holder of such put options. Accordingly, the Reporting Persons disclaim any beneficial ownership in any shares of Class A Common Stock that underlie such put options.
