Dear Rick:

It has been my privilege to serve as a member of the Board of Directors of ZixCorp since 1998. As you know, I have recently been appointed Chief Financial Officer of Computer Sciences Corporation and, as such, my expanded responsibilities will not allow me the time to properly represent the shareholder interests of ZixCorp. Accordingly, please accept my immediate resignation from the Board of Directors effective today.

I wish you, the board and the management team all the best success.

Very truly yours,

Michael E. Keane
