Mr. Zwanziger, at any time, and from time to time may acquire additional Common Shares or dispose of any or all of the Common Shares that he owns depending upon an ongoing evaluation of the investment in the Common Shares, prevailing market conditions, other investment opportunities, other investment considerations and/or other factors.

Except as disclosed herein, none of Janet Zwanziger, Zwanziger Family Ventures LLC or Zwanziger Ventures LLC have a plan or proposal which relate to, or could result in, any of the matters referred to in paragraphs (b) through (j) inclusive of the instructions to Item 4 of Schedule 13D.
