of the Company and Investor shall be binding upon and benefit the successors, assigns, heirs, administrators and transferees of

8.       Transfer
of this Note or Securities Issuable on Conversion Hereof. With respect to any offer, sale or other disposition of this
Note or securities into which such Note may be converted, Investor will give written notice to the Company prior thereto, describing
briefly the manner thereof, together with a written opinion of Investor's counsel, or other evidence if reasonably satisfactory
to the Company, to the effect that such offer, sale or other distribution may be effected without registration or qualification
(under any federal or state law then in effect). Upon receiving such written notice and reasonably satisfactory opinion, if so
requested, or other evidence, the Company, as promptly as practicable, shall notify Investor that Investor may sell or otherwise
dispose of this Note or such securities, all in accordance with the terms of the notice delivered to the Company. If a determination
has been made pursuant to this Section 10 that the opinion of counsel for Investor, or other evidence, is not reasonably
satisfactory to the Company, the Company shall so notify Investor promptly after such determination has been made. Notwithstanding
the foregoing, with respect to any offer, sale or other disposition of this Note or securities into which such Note may be converted
to any person or entity affiliated with Investor (an "Affiliated Party"), Investor will give written notice
to the Company prior thereto, describing briefly the manner thereof, and the Investor may transfer the Note to such Affiliated
Party as long as the Affiliated Party agrees in writing to be bound by the terms hereof as if such Affiliated Party was the original
Investor hereunder. Each Note thus transferred and each certificate representing the securities thus transferred shall bear a
legend as to the applicable restrictions on transferability in order to ensure compliance with the Securities Act, unless in the
opinion of counsel for the Company such legend is not required in order to ensure compliance with the Securities Act. The Company
may issue stop transfer instructions to its transfer agent in connection with such restrictions. Subject to the foregoing, transfers
of this Note shall be registered upon registration books maintained for such purpose by or on behalf of the Company. Prior to
presentation of this Note for registration of transfer, the Company shall treat the registered holder hereof as the owner and
holder of this Note for the purpose of receiving all payments of principal and interest hereon and for all other purposes whatsoever,
whether or not this Note shall be overdue and the Company shall not be affected by notice to the contrary.
