If any person who has not signed the registration statement is named therein as about to become a director, the written consent of such person shall be filed with the registration statement. Any such consent, however, may be omitted if there is filed with the registration statement a statement by the registrant, supported by an affidavit or affidavits, setting forth the reasons for such omission and establishing that the obtaining of such consent is impracticable or involves undue hardship on the registrant.
