reverse stock split (if any), post initial financing (whether that initial
financing be a single round or in multiple tranches over a period of time), and

Position in accordance with Rule 144 upon Seller’s request (except in the event
it is unlawful to do so in the reasonable opinion of Company’s counsel), or does
