The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the Common Stock under the Election Plan has been registered under a then currently effective registration statement under the Securities Act of 1933, as amended, or (ii) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates representing Common Stock issued under the Election Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws.
