18. Transfer of this Note.

If a determination has been made pursuant to this Section 17 that the opinion of counsel for the Payee, or other evidence, or the written acknowledgment from the desired transferee, is not reasonably satisfactory to the Maker, the Maker shall so notify the Payee promptly after such determination has been made. Each Note 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 Maker such legend is not required in order to ensure compliance with the

Securities Act. The Maker 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 on the books maintained for such purpose by or on behalf of the Maker. Prior to presentation of this Note for registration of transfer, the Maker shall treat the registered holder hereof as the owner and holder of this Note for the purpose of receiving all payments of principal hereon and for all other purposes whatsoever, whether or not this Note shall be overdue, and the Maker shall not be affected by notice to the contrary.
