form could not be eliminated without unreasonable effort or expense;

         [x] (b) (i) The subject annual report, semi-annual report, transition

PART III - NARRATIVE

Registrant is required to include in its financial statements forming part of
the subject report the results of Euro-Nocopi, SA ("Euro"), a French
corporation, based on the equity method of accounting. The financial information
concerning Euro necessary to complete the preparation of Registrant's financial
statements in accordance with such requirement has not yet been furnished to
Registrant by Euro. As a consequence, Registrant's management has been unable to
complete the preparation of Registrant's financial statements.

PART IV - OTHER INFORMATION

(1)  Name and address of person to contact in regard to this notification:

                           Thomas F. Hurley, Esq.
                           Hangley Aronchick Segal & Pudlin
                           One Logan Square - 27th Floor
                           Philadelphia, PA 19103
                           Telephone:  (215) 496-7056

(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
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

Based on information currently available to Registrant, its net loss is
anticipated to increase from approximately $550,000 for the fiscal year ended
December 31, 1998 to approximately $1,360,000 for the fiscal year ended December
31, 1999. The increase in net loss is primarily attributable to (a) the write
off during the fourth quarter of the fiscal year ended December 31, 1999 of
certain assets (primarily patents) due to the uncertainty with respect to the
Company's ability to recover the costs thereof (approx. $510,000); (b) severance
expenses associated with the termination of employment of certain executive
officers of Registrant (approx. $390,000); and (c) a year to year decrease in
operating revenues, less than fully offset by corresponding reductions in
expenses.

The foregoing does not reflect changes to Registrant's financial results that
may occur as a result of the inclusion therein of Euro's results in accordance
with the equity method of accounting. Such changes may increase or decrease
Registrant's net loss.
