that any future sale of shares of the Company’s capital stock could be at a premium or a discount to the Purchase Price, and such

on behalf of the Company.

and [his][their respective] affiliated and related entities’ entire ownership interest in the Company [(including any shares of
Company’s stock and options and other instruments, directly or indirectly held, or beneficially owned, by [●],
whether or not they are disclosed in this Agreement)[, except for the shares currently held by [●].

consequences of the Repurchase. Each of [●] and Stockholder is relying solely on such
advisors and not on any statements or representations of the Company or any of its Related Parties. Each of [●]
and Stockholder understands that [●] and Stockholder (and not the Company or any of
its Related Parties) shall be responsible for [●]’s and Stockholder’s tax
