                        Part II. Rule 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 appropriate box.)

[ X ]    (a) The reasons described in reasonable 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, 20-F, 11-K or Form N-SAR, 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 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
         12(b)-25(c) has been attached if applicable.


                               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. (Attach extra sheets if needed.)

         The quarterly report on Form 10-Q could not be filed within the
         prescribed time period because the registrants, together with their
         independent auditors, have not been able to complete the interim
         financial statements required to be included in the Form 10-Q in order
         for the Form 10-Q to be filed in a timely manner.

portion thereof?
