State below in reasonable detail the reasons why form 10-KSB, 11-K, 20-F, 10-QSB
or N-SAR or portion thereof could not be filed within the prescribed time
period.

The Registrant is unable to file its Annual Report on Form 10-KSB within the
prescribed time period because of the diversion of the Registrant's financial
management resources to efforts surrounding negotiations, finalization of
approvals, and administrative matters related to sales, proposed sales, and
proposed settlements with respect to the disposition of certain assets and
operations including the Registrant's Breece Hill Technologies subsidiary,
Magnum Technologies business, and operations related to the assets and licenses
purchased from Infinite Graphics Incorporated.

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

                                  James Geiser
                                 (612) 944-0400

     (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 report(s) been filed? If the answer is no,
identify report(s).

                                 [X] Yes [ ] No

     (3) Is it anticipated that any significant change in results 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 quantitively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

     Due to the sale of the Registrant's Magnum Technologies business, the
proposed settlement with respect to the assets and licenses purchased from
Infinite Graphics Incorporated, the proposed sale of the Registrant's Breece
Hill Technologies subsidiary, and a re-evaluation of the recoverability of
certain tangible and intangible assets during the fourth quarter of 1999, the
Registrant anticipates a charge of between $10 million to $12 million in
December 1999 related to these items. In addition, the Registrant anticipates
other operating losses, exclusive of the items above, of $9 million to $11
million in the fourth quarter of 1999, approximately $5 million to $6 million of
which are related to compensation paid to third parties through grants of equity
instruments. Based upon the September 30, 1999 year-to-date net loss of $7.4
million and upon consideration of the items above, the Registrant anticipates
the fiscal year 1999 net loss to be between $26 million and $30 million.
