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

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

following should be completed. (Check box if appropriate)

         [x] (a) The reasons described in reasonable detail in Part III of this
form could not be eliminated without unreasonable effort or expense;

         [ ] (b) (i) The subject annual report, semi-annual report, transition
report on Form 10-K, Form 20F, 11-K or Form N-SAR, or portion thereof will be

PART III - NARRATIVE

         Registrant's Chief Financial Officer, the officer primarily responsible
for preparing the subject report, has had a short-term, unexpected absence from
work due to a family emergency. He is expected to return to work in sufficient
time to permit Registrant to file the subject report within five days after its
due date, and Registrant's remaining staff has determined that it is appropriate
so to delay the filing of the subject report.


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.

Registrant expects to report earnings of approximately $830,000 and $610,000 for
the three months and six months, respectively, ending June 30,2003, as compared
to net losses of $246,800 and $472,100, respectively, for the same periods in
the prior year. The substantial improvement in operating results is due
primarily to Registrant's one time gain of $932.700 in the three months ended
June 30, 2003 ($875,300 for the six months then ended) reflecting the settlement
of the Registrant's dispute with its former affiliate, Euro-Nocopi, S.A.
