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
               12b-25(c) has been attached if applicable.



PART III. NARRATIVE

State below in reasonable detail the reasons why the Form 10-K, 11-K, 20F, 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 Company requires additional time to file its Form 10-K as a result of
ongoing negotiations with its creditors to amend an existing credit agreement
in order to cure a debt covenant violation that existed at December 31, 2000.
The Company requests additional time to file so that it may reach an agreement
with its creditors which will mitigate some uncertainty regarding the Company's
current sources of financing. The Company feels it would be more beneficial to
potential readers of the Form 10-K if the debt compliance issues were cured
prior to filing. The Company is hopeful that an agreement will be reached with
its creditors prior to the extended deadline. If an agreement cannot be reached,
however, the additional time also gives the Company sufficient time to ensure
accurate and detailed disclosure surrounding the currently existing
uncertainties and the Company's plans to secure amended financing.

     notification

     the corresponding period for the last fiscal year will be reflected by the
