**NYSE
      Group Announces Workforce Reduction**





New
      York,
      Nov. 8, 2006 - NYSE Group, Inc. (NYSE: NYX) today announced a workforce
      reduction of more than 500 positions, including approximately 400 employees
      and
      120 full-time consultants, from its NYSE, NYSE Arca and Securities Industry
      Automation Corporation (SIAC) business units. This organizational downsizing,
      which is effective immediately and extends through March 2007 for certain
      positions, excludes NYSE Regulation and reflects ongoing initiatives to cut
      costs and improve efficiencies, eliminate duplicate services, and leverage
      synergies resulting from the March 2006 NYSE-Archipelago merger. Since March
      2005 when NYSE, Archipelago Holdings, and SIAC had 3,484 employees on a combined
      pro forma basis, there has been a reduction of over 950 employees; excluding
      NYSE Regulation, this represents a 35% workforce reduction.




Individuals
      whose positions are being eliminated will receive separation packages, and
      those
      eligible will receive outplacement services and retirement benefits. As part
      of
      the terms of NYSE Group’s recent SIAC transaction, approximately 150 SIAC
      positions which are part of this workforce reduction will become part of the
      American Stock Exchange.
