EST PRIVATEBANCORP, INC. ANNOUNCES PLANNED EXPANSION TO MILWAUKEE Veteran Banker Jay Williams to lead The PrivateBank- Wisconsin Milwaukee, WI, April 21, 2004--PrivateBancorp, Inc. (Nasdaq: PVTB) today announced its intent to expand to the southeastern Wisconsin market with the opening of The PrivateBank- Wisconsin. The PrivateBank will operate in Wisconsin under the leadership of prominent Wisconsin banker Jay B. Williams, who will serve as managing director and chief executive officer. In addition, the Company's Nominating and Corporate Governance Committee has recommended that Williams be appointed to the board of directors of PrivateBancorp, Inc. and The PrivateBank and Trust Company. Ralph B. Mandell, Chairman, President and Chief Executive Officer of PrivateBancorp, Inc. said The PrivateBank is expected to open for business at an as of yet undisclosed downtown Milwaukee location by the end of 2004. "We are excited about the expansion into Milwaukee because it not only fulfills our strategic objective of pursuing selective growth opportunities in Midwestern markets, it also meets all of our highly selective expansion criteria," said Mandell. "There are opportunities to focus on target market segments and gain clients who are seeking the higher level of personalized service and broad array of banking and wealth management products that are the hallmark of The PrivateBank's core value proposition." "The key to success in any market requires a uniquely qualified individual at the helm who brings banking expertise, civic involvement and strong personal relationships," Mandell said. "This is a combination that has been very effective in PrivateBancorp's prior expansions in St. Louis and in suburban markets in the Chicago metropolitan area and Jay Williams brings all these attributes combined with a high energy level." "The PrivateBank - Wisconsin will be the standard bearer for PrivateBancorp's unique approach to private banking in the southeastern Wisconsin market," noted Williams. "Our clients, who will include individuals, small to middle market businesses and their owners, commercial real estate investors, and professionals, will benefit from a level of service and a range of products that we believe is not currently present in the market." Williams, who served as President of U.S. Bank Wisconsin from 2000-2003, has over 30 years of midwestern banking experience, with a strong emphasis on middle market banking and wealth management. In addition, he has served on numerous community boards, including United Way of Greater Milwaukee, Wisconsin Manufacturers and Commerce, Boys and Girls Clubs of Greater Milwaukee and YMCA of Metropolitan Milwaukee.
