PART II -- RULES 12B-25(B) AND (C)

If the subject  report could not be filed without  reasonable  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  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,  Form 20-F,  11-K or Form N-SAR,  or portion
               thereof,  will be filed on or before the  fifteenth  calendar day
               following  the  prescribed  due date;  or the  subject  quarterly
               report of transition report on Form 10-Q, or portion thereof will
               be filed on or  before  the  fifth  calendar  day  following  the

     [X]       (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 Forms 10-K, 11-K, 10-Q, N-SAR,
or the  transition  report or  portion  thereof,  could not be filed  within the
prescribed time period.

Since  the  end  of the  registrant's  fiscal  year  of  November  30,  1999,  a
significant Transaction has been entered into which is currently being asssessed
for its impact on the financial  statements and the disclosures  included in the
Annual  Report on Form 10K.  This  transaction  involves the  conversion  of the
Company's Grant Mill into a fossil fuel production plant in conjunction with the
University of Alaska, Fairbanks. The registrant is currently assesing the impact
of this and other  transactions  on its cash flow  requirements  for the  coming
financial  year.  Furthermore,  the  registrant  is in  the  process  of  making
financing  arrangements,  the  outcome of which may impact this  assessment.  In
order to ensure that certain assets and liabilities are appropriately  reflected
in the financial statements, the registrant is delaying the filing of its Annual
Report on Form 10K for the  financial  year  ended  November  30,  1999,  beyond
February 28, 2000.
