Although no Reporting Person has any specific plan or proposal to acquire or dispose of the Common Stock, the Reporting Person may, at any time and from time to time, acquire additional Common Stock or dispose of any or all of their Common Stock depending upon an ongoing evaluation of the investment in the Common Stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Client Accounts and Heartland’s fiduciary duty to such clients.
