l)       Changes in Status. If, before the issuance of any Shares to the Investor, the Investor’s investment intent as expressed herein materially changes, or if any change occurs that would make either the representations or warranties made by the Investor herein materially untrue or misleading, then the Investor shall immediately so notify the Company, and any prior acceptance of the subscription of the Investor shall be voidable at the option of the Company in its sole and absolute discretion.

IN WITNESS WHEREOF, the Investors execute and agree to be bound by this Subscription Agreement by executing this Signature Page to be effective as of March 15, 2019.
