&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Irwin Financial Corporation intends to disclose the following in connection with communications with some of the depositors of its subsidiary banks:  "Given national news of the past two weeks, we want to reassure you that we do not have any material exposure to Fannie Mae, Freddie Mac, Lehman Brothers, Washington Mutual or AIG.  We do not own the common or preferred stock of any of these entities.  We do own some mortgage backed securities issued or guaranteed by Fannie and Freddie, but the government's intervention was designed to protect the value of these securities.  We have some routine derivatives contracts with Lehman Brothers; however, they do not owe us anything on these contracts, so we have no exposure to losses from their bankruptcy."<BR>
