Item 1.01.  Entry Into a Material Definitive Agreement

      Amendments to Outside Director Stock Plans

      On December 8, 2005, the Board of Directors of Peapack-Gladstone Financial
Corporation (the "Corporation")  approved the adoption of amendments to the 1998
Stock  Option  Plan for  Outside  Directors  and the 2002 Stock  Option Plan for
Outside Directors.

      The  amendments  provide the  Compensation  Committee of the Board,  which
administers each of the plans, with the discretion to accelerate the vesting and
exercisability of options granted under the plans.

      Acceleration of Vesting

      In light of  upcoming  changes in the  accounting  for stock  options,  on
December 8, 2005,  the  Compensation  Committee  the Board of  Directors  of the
Corporation  authorized the accelerated  vesting of 79,200 stock options held by
outside  directors  under the  Corporation's  1998 Stock Option Plan for Outside
Directors  and 2002  Stock  Option  Plan  for  Outside  Directors.  Based on the
Corporation's  closing stock price of $28.25 per share on December 8, 2005,  all
of the total  accelerated  options have exercise prices above the closing market
price at the time of acceleration. The total weighted average price per share of
