Plans or Proposals The Reporting Person is the Chief Executive Officer and a member of the board of directors ("Board") of the Issuer. In this capacity, he may communicate with other members of management, other members of the Board, and/or other shareholders from time to time with respect to operational, strategic, financial or governance matters or otherwise work with management and the Board with a view to maximizing shareholder value. Such discussions and actions may be preliminary and exploratory in nature, and may not rise to the level of a plan or proposal. As an executive officer of the Issuer, the Reporting Person is eligible to receive, from time to time at the discretion of the Board or the compensation committee or other duly constituted committee thereof, equity awards pursuant to the Issuer's Omnibus Long Term Incentive Plan or other equity plans adopted from time to time. Such awards may consist of stock options, restricted share awards or restricted share units, which may be subject to vesting upon the satisfaction of time-based or performance-based vesting conditions.
