Head of Global Capital Markets Colm Kelleher to Assume CFO Role.

Morgan Stanley (NYSE: MS) announced that David H. Sidwell, Executive Vice President and Chief Financial Officer, has decided to retire from the Firm at the end of 2007. Colm Kelleher, who currently serves as the Head of Global Capital Markets, will replace Mr. Sidwell. Mr. Kelleher will join the Firm’s Management Committee and report to Chairman and Chief Executive Officer John J. Mack. Christopher Carter, who is currently Vice Chairman of Institutional Securities, will succeed Mr. Kelleher as Head of Global Capital Markets.

Mr. Sidwell, 54, joined Morgan Stanley in 2004. He has played a vital role in developing the Firm’s strategic growth plan and communicating it to the investment community. He also has played an important part in Morgan Stanley’s efforts to improve its risk-taking and capital allocation, which has helped the Firm deliver record financial performance in recent quarters.

Mr. Mack said, “David Sidwell has been a key member of our management team at Morgan Stanley and has helped lead the Firm through a period of significant change. His focus, insight and integrity have earned him tremendous credibility – both within Morgan Stanley and throughout the investment community. David informed me last year of his intention to retire, but agreed to stay on through the end of 2007 to ensure a smooth transition. I am pleased that in the months ahead, he will be working closely with Colm to help continue our positive momentum.”

Mr. Mack continued, “Colm Kelleher has proven himself a major asset to Morgan Stanley over the past 19 years, not only in his current role as Head of Global Capital Markets, but also as Co-Head of Fixed Income in Europe. He has been a leader in building client coverage teams and in advocating the further uniting of equity and debt capital markets. His experience as a business leader, combined with his training and expertise as a Chartered Accountant and his commitment to Morgan Stanley, make him extremely well-suited to serve in this critically important role.”

Mr. Sidwell said, “It has been a privilege to work with the talented team at Morgan Stanley, and play a part in our efforts to re-energize the Firm, improve its financial performance and lay a strong foundation for future profitable growth. Colm Kelleher brings a valuable business and client perspective along with accounting experience to the CFO post, and I look forward to working with him in the months ahead to continue building on Morgan Stanley’s success.”
