New York —

Morgan Stanley (NYSE: MWD) today announced it currently expects its 2005 second quarter earnings per diluted share to be approximately 15 - 20% below second quarter earnings per diluted share in 2004 of $1.10. The results were primarily driven by the weakened market conditions that the company had previously announced. The company is still in the process of preparing second quarter financial statements and it is currently not anticipating a change in the Coleman litigation reserve.
