                                     PART II
                             RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense

                                    PART III
                                    NARRATIVE

         State below in reasonable detail the reasons why the Forms 10-K, 11-K,
20-F, 10-Q, N-SAR, or the transition report or portion thereof, could not be
filed within the prescribed time period. (Attach Extra Sheets if Needed).

      On August 21, 1998, the Registrant's facility in St. Francisville,
Louisiana was severely damaged by a fire, which necessitated the closure of the
facility. The Company is currently assessing the financial impact of the loss
and, in connection therewith, negotiating a settlement agreement with the
insurance carrier as well as its largest secured creditor which has a lien on
the assets. If these negotiations are successful, the Company might avoid the
need to record a significant loss due to the fire at September 30, 1998. As a
result, the Registrant requires additional time to properly determine the
financial impact, if any, of these events on its financial statements and in its
Annual Report on Form 10-KSB for the fiscal year ended September 30, 1998. These
accounting issues could not be resolved without unreasonable effort or expense
in order to file the Form 10-KSB within the prescribed time period.

      The registrant expects to file the Annual Report on Form 10-KSB for the
fiscal year ended September 30, 1998 on or before January 13, 1999.

                                     PART IV
                                OTHER INFORMATION

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

   Charles E. Coppa             781                         224-2411
      (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 reports) been filed? If answer is no,
identify report(s).

                                                          |X|  Yes     |_|  No

         (3) Is it anticipated that any significant change in result 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.
