Part II-Rules 12b-25(b) and (c)

If the subject report could not be filed without  unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate.)


               (a)  The  reasons  described  in  detail in Part III of this form
                    could  not be  eliminated  without  unreasonable  effort  or
                    expense;

   [ X ]       (b)  The subject annual report,  semi-annual  report,  transition
                    report on Form  10-K,  Form 20-F,  Form 11-K,  Form N-SAR or
                    Form N-CSR, or portion  thereof,  will be filed on or before
                    the 15th calendar day following the  prescribed due date; or
                    the subject  quarterly  report or transition  report on Form
                    10-Q,  or  subject  distribution  report  on Form  10-D,  or
                    portion  thereof  will  be  filed  on or  before  the  fifth
                    calendar day following the prescribed due date; and

               (c)  The accountant's statement or other exhibit required by Rule
                    12b-25(c) has been attached if applicable.

Due to the reasons stated below,  the Registrant could not have timely filed its
Form 10-Q for the fiscal  period ended  December  23, 2005 without  unreasonable
effort or expense. This Form 10-Q will be filed no later than the fifth calendar
day following the prescribed due date.

Part III-Narrative

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

The Registrant requires additional time to prepare and file its Quarterly Report
on Form 10-Q for the nine months ended  December 23, 2005. The decision to delay
the filing of the  quarterly  report was made to provide  management  additional
time necessary to complete its review.  The issues under review are not expected
to impact the operating  results announced by the Registrant on January 27, 2006
in its filing on Form 8-K.


(Attach extra sheets if needed.)

     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
