OUR OPPORTUNITY
================================================================================


*  As a $1.5 billion institution we have the opportunity to increase our
   long-term growth rate by acquiring larger lending and deposit relationships.

*  We know long-term shareholder value is created through core banking and
   attractive branch networks. We will seek to thoughtfully expand the branch
   system.

*  Though we view ourselves as builders in the shorter term, we will continue to
   do so as long as our strategy continues to create shareholder value.
