                           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 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;

         (b)      The subject annual report, semi-annual report, transition
                  report on Form 10-K, 10-KSB, 20-F, 11-K or Form N-SAR, or

                                  PART III
                                  NARRATIVE

         State below in reasonable detail the reasons why Form 10-K, 10-KSB,
11-K, 20-F, 10-Q, 10-QSB, N-SAR or the transition report portion thereof
could not be filed within the prescribed time period. (Attach extra sheets
if needed.)

         Applied Digital Solutions, Inc. ("ADS") and its now former outside
auditing firm, Grant Thornton LLP, have had a disagreement on the proper
accounting treatment with respect to certain options, and as a result, in
part, of this disagreement, Grant Thornton communicated its resignation as
ADS's auditors in a letter dated May 14, 2002. Grant Thornton advised ADS
that it has not completed its review of ADS's quarterly report on Form 10-Q
for the first quarter of 2002 and should not be associated with that report
in any way. Accordingly, ADS is unable to file its Form 10-Q within the
prescribed deadline and otherwise in accordance with applicable SEC rules
and regulations without, among other things, unreasonable effort and
expense.

         The options in question (about which ADS and Grant Thornton have
had the disagreement) are options that Medical Advisory Systems, Inc.
("MAS") was to assume or convert into MAS options under the terms of an
agreement and plan of merger, dated November 1, 2001, by and among MAS, a
MAS wholly-owned subsidiary, and Digital Angel Corporation ("Old Digital
Angel Corporation"), in which ADS held a controlling interest. On March 27,
2002, the MAS wholly-owned subsidiary was merged with and into Old Digital
Angel Corporation under the terms of the merger agreement. Old Digital Angel
Corporation, as the surviving corporation, became a wholly-owned subsidiary
of MAS, which has since been renamed Digital Angel Corporation ("New Digital
Angel Corporation"). Grant Thornton has also communicated by letter dated
May 14, 2002, the termination of its auditor relationship with New Digital
Angel Corporation.


                                  12b25-2




         With respect to the dispute as to the proper accounting treatment
for these options, Grant Thornton's position is that ADS should recognize in
the first quarter of 2002 a one-time, non-cash, compensation expense, in the
amount of approximately $14.5 million, under the guidance provided by
Accounting Principles Board Opinion No. 25 (APB 25). ADS is of the view that
the cost of the assumed- or to-be-converted options represents part of the
merger consideration and should be capitalized and reflected on ADS's
balance sheet, consistent with accounting for the transaction as a business
combination using the purchase method of accounting, in accordance with
Accounting Principles Board Opinion No. 16 (APB 16). ADS intends to consult
the staff of the Securities and Exchange Commission with respect to this
issue.
