NOW, THEREFORE, in contemplation of the foregoing and in consideration of the mutual agreements, covenants, representations and warranties contained herein and intending to be legally bound hereby, the parties agree as follows: 1. Agreement on Transfer and Sale of Shares. 1.1 Transfer and Encumbrance.

If after the execution hereof, the Stockholder should die or become incapacitated, or if any trust or estate holding the Shares or New Shares (as applicable) should be terminated, or if any corporation or partnership holding the Shares or New Shares (as applicable) should be dissolved or liquidated, or if any other such similar event or events shall occur, certificates representing the Shares or New Shares (as applicable) shall be delivered by or on behalf of the Stockholder in accordance with the terms and conditions of this Agreement, and actions taken by CMCO hereunder shall be as valid as if such death, incapacity, termination, dissolution, liquidation or other similar event or events had not occurred, regardless of whether or not CMCO has received notice of such death, incapacity, termination, dissolution, liquidation or other event. 4.
