Investor further understands that the Shares may not be sold, offered for sale, pledged, hypothecated or otherwise transferred except pursuant to an effective registration statement under the act or upon receipt by the company of an opinion of counsel satisfactory to the company that registration is not required under the act or unless sold pursuant to Rule 144.

k)       Indemnification. The Investor hereby indemnify and hold harmless the Company and the Company’s respective officers, directors, shareholders, employees, attorneys and agents, as the case may be, from and against all damages suffered and liabilities of any kind incurred by any of them (including costs of investigation and defense and attorneys’ fees) arising out of any inaccuracy in the agreements, representations, covenants and warranties made by the Investor in this Subscription Agreement.

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.
