              RONALD PETTENGILL RESIGNS AS PREDICTIVE SYSTEMS' CEO

New York, NY, March 30, 2001 - Predictive Systems (NASDAQ: PRDS), a leading
network infrastructure consulting firm, today announced that Ronald Pettengill,
the company's CEO and co-founder, will step down from his role as CEO and
Chairman of the Board. Mr. Pettengill will continue to serve on the company's
Board of Directors. William Wyman, a director of the company, has been elected
CEO and Chairman of the Board. Mr. Wyman will serve in this capacity pending the
conclusion of a successful search for a new CEO. Robert Belau, Predictive
Systems' president and co-founder, will continue as president with the same
responsibilities and will report to Mr. Wyman.

A board member since 1999, Mr. Wyman worked at Booz Allen & Hamilton, a large
international consulting firm, the last five years of which he was president of
management consulting. In 1984, he started his own firm, Oliver Wyman & Company,
now a leading provider of consulting services to the top executives of large
financial institutions. Since 1995, Mr. Wyman has been a business advisor and
counselor on a broad range of issues to a number of corporate chief executives
of financial services, information services, forest products and software
companies.

"Over the past six years, I have had the pleasure of building a start-up into a
global corporation, leading a team of top-flight management and working with
some of the best and brightest professionals in the industry. Frankly, I'm
looking forward to taking a break and spending time with my family," said
Pettengill, who is leading the search for a replacement with the assistance of
executive search firm, Russell Reynolds. "I am incredibly proud of the company
we've created and the level of service we continue to provided to a stellar list
of Fortune 1000 companies and remain steadfastly optimistic about the company's
future."

"Ron has made innumerable contributions to the growth and success of Predictive
Systems, having guided us through a successful public offering and successfully
leading our global expansion," said Wyman. "I am confident however, that the
solid foundation that he helped create will enable us to continue to build on
our success and remain a leading network infrastructure company."
