Exhibit 99.1

This is a follow up to the memo sent out yesterday regarding CTM’s opportunities. As noted and discussed with all of you yesterday, we have been engaged in strategic discussions related to supporting the continued pace of growth of CTM relative to the size and ongoing strategy of CTB. I am now able to disclose more about those discussions.

Over the past three (3) months, we have talked with a significant number of potential financial partners. Many of the potential partners are private equity firms with a desire to establish a major presence in mortgage banking. These discussions have progressed and we are currently in more detailed discussions with several private equity firms. As noted yesterday, the non-bank segment of the mortgage banking industry has grown dramatically in the last several years. Therefore, this is a very exciting time to work with private equity to determine how to build a major mortgage market participant.

At the same time, the merger between MB Financial and Cole Taylor Bank results in a much larger financial institution where there will be opportunities for CTM to grow. In order to better understand the opportunity with MB Financial, we are initiating more in-depth discussions with executives from MB starting this Thursday.

Hopefully the ongoing discussions with potential partners including MB Financial will provide additional clarity to the paths available to CTM in building our business to its full potential. As noted yesterday, the bottom line in all of this is that we are working to provide all of you, all of us, the opportunity to reach our full potential at CTM.

We will provide you with additional information, to the best of our abilities, as these discussions evolve. For many reasons, this is an exciting time here at CTM. As always, my commitment is to lead the team to its full potential at CTM.

Please direct any questions to the senior executive leader of your team.
