9. Effectiveness of the Plan and Amendments
The Plan and any amendments requiring shareholder approval pursuant to Article 8 are subject to approval by vote of the shareholders of the Corporation within 12 months after their adoption by the Board. Director Shares may be awarded prior to shareholder approval of amendments, but any Director Share award requiring such amendments shall be subject to the approval of the amendments by the shareholders. The date on which any Director Shares awarded prior to shareholder approval of the amendment are awarded shall be the Date of Grant for all purposes of the Plan as if the Director Shares had not been subject to such approval. Any Director Shares awarded subject to shareholder approval of an amendment and any dividends payable thereon are subject to forfeiture if such shareholder approval is not obtained.
