Item 4.01 - Changes in Registrant's Certifying Accountant

a.   Previous independent registered public accounting firm

     i.   On September 24, 2004,Castelle dismissed PricewaterhouseCoopers LLP as
          its independent  registered  public  accounting firm. The Registrant's
          Audit  Committee  participated  in and approved the decision to change
          independent registered public accounting firms.

     ii.  The reports of PricewaterhouseCoopers  LLP on the financial statements
          for the  past  two  fiscal  years  contained  no  adverse  opinion  or
          disclaimer  of  opinion  and  were not  qualified  or  modified  as to
          uncertainty, audit scope or accounting principles.

     iii. During the two most  recent  fiscal  years and through  September  24,
          2004, there have been no disagreements with PricewaterhouseCoopers LLP
          on  any  matter  of  accounting  principles  or  practices,  financial
          statement   disclosure,   or  auditing   scope  or   procedure,   with
          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 two most  recent  fiscal  years and through  September  24,
          2004,  there have been no reportable  events (as defined in Regulation
          S-K Item 304(a)(1)(v)).

     v.   The Registrant has requested that  PricewaterhouseCoopers  LLP furnish
          it with a letter addressed to the SEC stating whether or not it agrees
          with the above statements.  A copy of such letter, dated September 24,
          2004 is filed as Exhibit 16.1 to this Form 8-K.

 b.   New independent registered public accounting firm

     i.   The  Registrant  engaged  Grant  Thornton  LLP as its new  independent
          registered public accounting firm as of September 24, 2004. During the
          two most recent  fiscal  years and through  September  24,  2004,  the
          Registrant has not consulted with Grant Thornton LLP regarding  either
          (i)  the   application   of  accounting   principles  to  a  specified
          transaction,  either  completed  or  proposed;  or the  type of  audit
          opinion  that  might  be  rendered  on  the   Registrant's   financial
          statements,   and  neither  a  written  report  was  provided  to  the
          Registrant  nor oral  advice  was  provided  that Grant  Thornton  LLP
          concluded  was an important  factor  considered  by the  Registrant in
          reaching  a  decision  as to the  accounting,  auditing  or  financial
          reporting  issue;  or (ii) any matter that was either the subject of a
          disagreement,  as  that  term is  defined  in  Item  304(a)(1)(iv)  of
          Regulation S-K and the related instructions to that
          Item,  or a  reportable  event,  as that term is defined in Item 304
         (a)(1)(v) of Regulation S-K.
