ATAI further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Shares, and on requirements relating to the Company which are outside of ATAI’s control, and which the Company is under no obligation and may not be able to satisfy.
