Item 4.01     CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

(a)  Previous independent registered public accounting firm

     (i)  On September 11, 2007, AmBase Corporation (the "Registrant") dismissed
          PricewaterhouseCoopers   LLP  as  its  independent  registered  public
          accounting firm. The  Registrant's  Accounting and Audit Committee and
          the Board of  Directors  participated  in and approved the decision to
          change its independent registered public accounting firm.

     (ii) The reports of PricewaterhouseCoopers  LLP on the financial statements
          for the fiscal  years ended  December  31, 2005 and 2006  contained no
          adverse  opinion or  disclaimer  of opinion and were not  qualified or
          modified as to uncertainty, audit scope or accounting principle.

     (iii)During the fiscal  years ended  December 31, 2005 and 2006 and through
          September   11,   2007,   there  have  been  no   disagreements   with
          PricewaterhouseCoopers  LLP on any matter of accounting  principles or
          practices,  financial  statement  disclosure,  or  auditing  scope  or
          procedure,  which disagreements if not resolved to the satisfaction of
          PricewaterhouseCoopers  LLP would have caused  them to make  reference
          thereto in their reports on the financial statements for such years.

     (iv) During the fiscal  years ended  December 31, 2005 and 2006 and through
          September 11, 2007,  there have been no reportable  events (as defined
          in Item 304(a)(1)(v) of Regulation S-K).

     (v)  The Registrant has requested that  PricewaterhouseCoopers  LLP furnish
          it with a letter  addressed to the Securities and Exchange  Commission
          stating whether or not it agrees with the above statements.  A copy of
          such letter, dated September 14, 2007, is filed as (Exhibit 16 to this
          Form 8-K).

(b)  New independent registered public accounting firm

     (i)  The  Registrant  engaged  UHY  LLP as its new  independent  registered
          public  accounting  firm as of September  11, 2007.  During the fiscal
          years ended December 31, 2005 and 2006 and through September 11, 2007,
          the  Registrant  has not  consulted  with UHY LLP regarding any of the
          matters  described  in  Item  304(a)(2)(i)  or Item  304(a)(2)(ii)  of
          Regulation S-K.
