                             RULE 12b-25 (b) AND (c)

following  should  be  completed.  (Check  box  if  appropriate.)



         |(a)  The  reasons  described  in  reasonable  detail  in  Part  III of
         |     this  form could not be eliminated without unreasonable effort or
         |     expense;
         | (b)  The  subject  annual  report,  semi-annual  report,  transition
         |     report  on Form 10-K, 20-F, 11-K or Form 10-Q, or portion thereof
         |     will  be  filed  on or before the 15th calendar day following the
  [X]    |     prescribed  due  date;  or  the  subject  quarterly  report  or

                                    PART III
                                    NARRATIVE

     State  below  in  reasonable  detail the reasons why Form 10-K, 11-K, 20-F,
10-Q,  N-SAR  or the transition report portion thereof could not be filed within
the  prescribed  time  period.

     The  registrant  is in the process of preparing and reviewing the financial
information  of  the  Company on a consolidated basis.  The process of compiling
and  disseminating  the information required to be included in the Form 10-Q for
the relevant fiscal quarter, as well as the completion of the required review of
the  Company's  financial  information  on  a  consolidated  basis, could not be
completed  without  incurring  undue  hardship  and  expense.  The  registrant
undertakes  the  responsibility to file such quarterly report no later than five
days  after  its  original  date.


                                     PART IV
                                OTHER INFORMATION

(1)  Name  and  telephone  number  of  person  to  contact  in  regard  to  this
notification

        Gabriel  B.  Vegh       (510)                       354-0300
             (Name)          (Area  Code)              (Telephone Number)

(2)  Have  all  other periodic reports required under Section 13 or 15(d) of the
Securities  Exchange  Act of 1934 or Section 30 of the Investment Company Act of
1940  during  the  preceding  12  months  or  for  such  shorter period that the
registrant was required to file such report(s) been filed?  If the answer is no,
identify  report(s).

                                 [x] Yes [ ] No


(3)  Is it anticipated that any significant change in results of operations from
the  corresponding  period  for  the  last  fiscal year will be reflected by the
earnings  statements  to  be  included in the subject report or portion thereof?

                                 [x] Yes [ ] No

If  so:  attach  an  explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of  the  results  cannot  be  made.

     For  the  quarter  ended  June  30,  2004,  the  registrant had revenues of
approximately  $578,000  and  a  net loss of approximately $(2,673,000). For the
quarter  ended  June  30,  2005,  the registrant currently estimates that it had
revenues of approximately $510,000 and a net loss of approximately $(2,452,000).
Results  for  this  relevant fiscal quarter remain subject to further adjustment
and actual results may differ significantly from the foregoing estimates.
