         On April 11, 2001 the Registrant, Digital Angel Corporation, filed
a Current Report on Form 8-K reporting the acquisition of the Advanced
Wireless Group from Applied Digital Solutions, Inc. By this amendment the
Registrant is filing the required financial statements and pro forma
financial information.



Item 7.  Financial Statements and Exhibits.

(a)      Financial statements of business acquired:

         Financial statements for the Advanced Wireless Group as of December
         31, 2001 and 2000, and for each of the three years in the three
         year period ended December 31, 2001.

         On April 18, 2002, Applied Digital Solutions, Inc. ("ADS") changed
         its certifying accountant from PricewaterhouseCoopers LLP ("PwC")
         to Grant Thornton LLP. Prior to the merger of Digital Angel
         Acquisition Co., a wholly-owned subsidiary of the Registrant, with
         and into the former Digital Angel Corporation ("Digital Angel"),
         Digital Angel was a wholly-owned subsidiary of ADS. On May 14,
         2002, Grant Thornton LLP resigned due to a disagreement with ADS
         concerning the proper treatment with respect to certain options.
         The Registrant has not engaged an outside auditing firm to replace
         Grant Thornton LLP. Until the interim financial statements
         contained in the Registrant's Quarterly Report on Form 10-Q have
         been reviewed by an independent public accountant, PwC has
         indicated its intention not to consent to the use of its report on
         the Advanced Wireless Group's consolidated financial statements as
         of and for the year ended December 31, 2001 required pursuant to
         Rule 3-05(b)(2) of Regulation S-X. As a result of the foregoing,
         the Registrant has included as an exhibit to this report the
         Advanced Wireless Group's unaudited consolidated financial
         statements as of December 31, 2001 and 2000 and for the three year
         period ended December 31, 2001.

         Form 10Q for Digital Angel Corporation as of March 31, 2002, and
         for the three months ended March 31, 2002 and 2001, incorporated by
         reference to Digital Angel's Form 10-Q filed on May 20, 2002.

(b)      Pro forma financial information

         Pro forma financial information for the year ended December 31,
         2001 and the three months ended March 31, 2002.

(c)      Exhibits.

         99.3  Financial statements of the Advanced Wireless Group as of
               December 31, 2001 and 2000 and for each of the three years in
               the three-year period ended December 31, 2001.

         99.4  Pro forma financial information.
