      Van der Moolen Holding NV (NYSE:VDM) (Amsterdam:VDMN) is pleased to 
      announce an agreement in principle to acquire a 100% interest in Robbins 
      & Henderson LLC (R & H), a US based institutional broker. R & H offers a 
      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.”

      thereby accelerating the growth of this effort.”
