Terms of the contract were not disclosed. "The proprietary e-business financial service offerings we are developing with MicroStrategy will provide Ameritrade with a competitive advantage that will be very hard to match," said Thomas K. Lewis, Jr., co-chief executive officer, Ameritrade Holding Corporation. "Working with the MicroStrategy technology, we will be able to process massive amounts of financial intelligence and proactively broadcast it directly to our customers. In addition to this unprecedented level of personalized financial insight and analysis, including 24x7 stock alerts, we also will be able to offer our customers the ability to act immediately to execute transactions via a wide range of wireless devices such as pagers, cellular phones, and PDAs," Lewis added. "This agreement with Ameritrade marks MicroStrategy's emergence as a strategic player in the e-business industry," said Michael J. Saylor, president and chief executive officer of MicroStrategy. "MicroStrategy's core technology strength is to extract insight from massive databases to provide organizations with better intelligence on their business and their customers. With Ameritrade we will leverage this expertise to develop financial applications that are proactive and personalized, allowing them to reach customers in unique ways, and provide customers with unmatched financial services." "Our goal is to enable Ameritrade to add business intelligence to e- commerce applications," said John Wyatt, president of MicroStrategy's E-Business Division. "With Ameritrade, we want to go beyond simple transactions over a web site to developing solutions that enable the company to capture data and use that data to proactively interact with its customers via the communication device of their choosing. We believe that Ameritrade is leading the industry in developing e-business applications that provide significant value to its customers." Wyatt added that this alliance could potentially include millions of software licenses to cover Ameritrade's rapidly growing customer base. According to Lewis, "We believe that the products and services that will result from our alliance with MicroStrategy will help fuel the next wave of growth in online investing. We envision a day in the not so distant future when we can utilize technology to automatically notify customers via cell phone, pager or email that a stock they have been watching is moving and a decision to buy, sell or hold is needed and with the press of a button they'll be able to respond. That's where the industry is going and we plan to be there first." 1 About Ameritrade Holding Corporation Ameritrade Holding Corporation is a pioneer in the discount and online brokerage industry.
