Schedule of Information Contained in this Report: 1. The English language press release of Van der Moolen Holding N.V. dated October 9, 2006 announcing that Van der Moolen anticipates a significant decline of third quarter 2006 revenues. Van der Moolen Anticipates a Significant Decline of Third Quarter 2006 Revenues AMSTERDAM--(BUSINESS WIRE)--Oct. 8, 2006--Van der Moolen announces that, based on current information, it anticipates reporting a significant decline of consolidated revenues compared to the second quarter of 2006. This reduction is mainly caused by an approximate 30% decline in VDM Specialists USA's principal trading revenues (dollar value) compared to the previous quarter. The developments in the USA, including the outsourcing of clearing activities, have resulted in a reduction of staff. Related severance payments are estimated to negatively affect net income for the third quarter by approximately EUR 0.4 million. As a result of abovementioned factors Van der Moolen anticipates a net loss attributable to common shareholders for the third quarter 2006. In the light of the developments in the USA the board has decided that an impairment test will be performed on the intangible assets allocated to this entity. The impairment test will be performed in due consultation with external advisors. On October 6, 2006, the New York Stock Exchange started the implementation of the Hybrid Market trading system (Phase III). According to the New York Stock Exchange, the full roll-out of this system is expected to be finalized prior to year end. As a result of the change in the trading system, Van der Moolen anticipates further staff reductions. These figures are preliminary estimates.
