Schedule of Information Contained in this Report: 1. The English language press release of Van der Moolen Holding N.V. dated January 2, 2006 announcing that Van der Moolen closes acquisition of Curvalue. Van der Moolen closes acquisition of Curvalue; Richard den Drijver, CEO of Curvalue, nominated to Van der Moolen's Executive Board; Mr. den Drijver expected to succeed Mr. Boettcher as Chief Executive in 2006 AMSTERDAM, Netherlands--(BUSINESS WIRE)--Jan. 2, 2006--Van der Moolen is pleased to announce that its acquisition of Curvalue Financial Services was completed on January 2, 2006. All assets and liabilities of Curvalue, including its undistributed retained earnings for the full calendar year 2005, are consolidated with those of Van der Moolen Holding NV from that date. We expect operational integration of the two firms to be complete by the end of 2006. Although we will seek to maximize the cost savings made possible by the combination, we anticipate few if any staff reductions as a result of the acquisition. Most of the synergies arising from the combination will be on revenue rather than cost lines. With the integration of Curvalue and some additional development work, Van der Moolen's business will consist of three key activities, each offering considerable potential: -- We expect our NYSE specialist unit to adapt successfully in the new Hybrid market environment, and if the history of changes to the NYSE's market model is any guide, the Hybrid will stimulate trading activity. While our specialist unit will continue to be primarily dependent on external conditions to drive its growth, its fixed costs and capital intensity will be reduced. -- Our European trading activities will be greatly expanded, and significantly improved in quality. With increased scope and scale, and with solid reserves of intellectual capital and technological sophistication to draw on, they will be able to create a virtuous circle of innovation driving revenues which can fund further innovation. -- Starting from a competitively advantageous position, the Online Trader brokerage activity that we have acquired with Curvalue will have very substantial room for growth, not only in Europe but throughout the world. We want Online Trader to be the portal through which our customers worldwide can access all public markets in any instrument. Longer term, we expect integration to become more complete as we introduce principal facilitation to the Online Trader platform. Richard den Drijver, founder and CEO of Curvalue, has been nominated to the Executive Board of Van der Moolen Holding NV, subject to the approval of the Annual General Meeting of Shareholders scheduled for April 5, 2005. F.M.J. Boettcher, CEO of Van der Moolen, remarked, "We are delighted to welcome the management and staff of Curvalue to the Van der Moolen Group. We believe that the combined firms are truly greater than the 'sum of their parts,' offering exciting growth opportunities well beyond the initially realizable cost synergies. This acquisition fulfills our strategic requirements for an activity that reinforces our European presence, returns us to derivative trading and provides us with the means to develop an institutional customer business. Moreover Curvalue brings us an excellent successor for my position." Van der Moolen will announce its earnings for the full year 2005 on February 23, 2006, at which time we will outline the strategy for the combination of Curvalue and Van der Moolen in more detail. As a result of the closing, the date of the Q1/2006 earnings release is amended to May 18, 2006. For more information about Van der Moolen, please visit www.vandermoolen.com.
