Since joining NASDAQ in May 2003, Greifeld has taken steps to sharpen the company's strategic direction, focusing its mission on being the premier U.S. equities market. The market's focus is to provide the most efficient, transparent trading platform for investors by leveraging NASDAQ's advanced trading technology; to capture the majority of U.S. IPOs and attract listings from competitive exchanges.

Tapping his 20-year industry experience and leadership with electronic trading systems, Greifeld has led a significant enhancement of NASDAQ's trading offerings. In March 2004, he oversaw the launch of NASDAQ's market center-a newly integrated system capable of trading of NASDAQ, NYSE, AMEX-listed securities and exchange traded funds on a single electronic platform. In January of 2004, Greifeld spearheaded NASDAQ's innovative "dual listing" program, which for the first time allowed NYSE-listed companies to list on NASDAQ. This innovative initiative made worldwide news and significantly ratcheted up the debate regarding efficient electronic markets versus manual, floor-based exchanges. Greifeld has been a vocal advocate for modernizing market structure and increasing public company CEO attention on the performance and quality of stock markets for the benefit of company shareholders and all investors.

In May 2004, Greifeld led NASDAQ's decision to acquire BRUT ECN from SunGard Data Systems (NYSE: SDS). The BRUT acquisition provides NASDAQ trading systems with additional capabilities, including advanced order routing. Most recently, in April 2005, NASDAQ announced a definitive agreement to purchase the INET ECN.

Greifeld is an active speaker on financial market structure and regulatory issues. He has been vocal in Washington regarding enhancements to Sarbanes-Oxley for small companies and the use of stock options as a tool for business and economic growth. Greifeld has addressed organizations including The Investment Company Institute, the National Press Club, and the World Economic Forum.

Prior to joining NASDAQ, Greifeld was an Executive Vice President with SunGard Data Systems Inc., a $6.2 billion market cap company, where he was responsible for all of SunGard's sell-side businesses and its buy-side transaction routing businesses. While serving as President Chief Operating Officer of Automated Securities Clearance, Inc. (ASC) from 1991-1999, Mr. Greifeld led the team that created BRASS and made it the industry standard trade order management system for NASDAQ stocks.

Greifeld holds a Masters in Business from New York University, Stern School of Business and B.A. in English from Iona College. His graduate school thesis was on the operation of The NASDAQ Stock Market.

Greifeld is an avid runner and has completed four marathons. He was recently named Chairman of the USA Track & Field Foundation.
