    AMSTERDAM, Netherlands--(BUSINESS WIRE)--July 26, 2007--Van der
Moolen Holding NV (NYSE:VDM) (Amsterdam:VDMN) is pleased to announce
an agreement in principle to acquire a 100% interest in Robbins &

wide variety of brokerage services through an experienced team of
industry professionals. Gross revenue in 2006 was $ 6.4 million.

    The acquisition will be subject to regulatory consent.

    The acquisition price is based on the earnings of R&H for the
years 2006, 2007 and 2008. For 2006 the price amounts $ 2 million. The
acquisition price for 2007 and 2008 respectively will be the net
profit for the year multiplied by factor 4.5 for 2007 and factor 4 for
2008. R&H will be included in the VDM figures as of third quarter 2007
earnings.

    Richard den Drijver, CEO of VDM: "This acquisition marks the start
of a brokerage division for VDM in the US. This will bring us closer
to achieving our goal to become a Global Securities Firm in 3 time
zones acting as a liquidity provider, a broker and an investor and
developer of exchanges. With R&H we can now offer professional
services to our broker clients in the US."

    Tom Hearden, CEO of R & H: "Together, VDM and R & H will provide a
suite of products and services that will enable our customers to be
competitive in a global arena. Additionally, this will enhance our
ability to recruit experienced investment professionals thereby
accelerating the growth of this effort."

    VDM furthermore announces that it has sold 123,646 NYSE shares in
July 2007 at an average price of $ 74.36. The remaining number of
shares VDM owns is 175,476.
