|6. | Transfer of this Note.
        With respect to any offer, sale or disposition of this Note, the Holder
        will give written notice to the Company prior thereto describing briefly
        the manner thereof together with a written opinion of such Holders
        counsel, to the effect that such offer, sale or disposition may be effected
        without registration or qualification (under any federal or state law
        then in effect) and that the requirement of Section 5 of this Note have
        been met. Promptly upon receiving such written notice and reasonably satisfactory
        opinion, the Company, as promptly as is practicable, shall notify such
        Holder that such Holder 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 Section 6
        that the opinion of counsel for the Holder is not reasonably satisfactory
        to the Company, the Company shall so notify the Holder promptly after
        such determination has been made.

        shall bear a legend as to the applicable restrictions on transferability
        in order to ensure compliance with the Securities Act of 1933, as amended
        (the Act), unless in the opinion of counsel for the Company,
        such legend is not required in order to ensure compliance in the Act.
        The Company may issue stop transfer orders in connection with such restrictions.
