     The English language press release of Van der Moolen Holding N.V. dated

           Van der Moolen Announces Reduction in Workforce
                  at Van der Moolen Specialists USA


    AMSTERDAM, The Netherlands--(BUSINESS WIRE)--Jan. 23, 2007--Van
der Moolen Holdings, N.V. announced today that its Van der Moolen
Specialists, USA, LLC unit (VDMS) will implement an immediate
reduction in work force of approximately 30%. This action is being
taken as the NYSE completes the move of all listed securities to its
new Hybrid Market system later today.

    The staff reduction is expected to yield annualized savings of
approximately $4.5 million dollars going forward and will result in a
one-time charge for severance costs of approximately $1.3 million
dollars to VDMS first quarter 2007 earnings.

    "This is a difficult decision, but one which is necessary for VDMS
due to implementation of the NYSE Hybrid market and more automation at
the point of sale" said Richard E. den Drijver, CEO of Van der Moolen
Holding NV.
