Item 1.  Change in Control of Registrant

         Effective March 27, 2002, the Registrant, Digital Angel Corporation
(formerly known as Medical Advisory Systems, Inc. (MAS)) completed its
merger pursuant to a November 1, 2001 Agreement and Plan of Merger, as
amended (the "Merger Agreement") with Applied Digital Solutions, Inc. (ADS),
its wholly owned subsidiary, Digital Angel Corporation, and Digital Angel
Acquisition Co., a wholly-owned subsidiary of the Registrant. Prior to this
transaction, ADS was a 16.6% beneficial owner of the Registrant.

         Pursuant to the Merger Agreement, the Registrant acquired from ADS
the Advanced Wireless Group of ADS, which consisted of 100% of the
outstanding shares of common stock of Digital Angel Corporation and Timely
Technology Corp., and 85% of the outstanding shares of common stock of
Signature Industries, Limited. Each issued and outstanding share of Digital
Angel common stock held by ADS was converted into 0.9375 shares of MAS
common stock, or 18,750,000 shares of MAS common stock.

         In satisfaction of a condition to the consent to the merger of IBM
Credit Corporation, a secured creditor of ADS, the shares held by ADS were
transferred to the Digital Angel Share Trust, a Delaware statutory business
trust controlled by an advisory board. As a result, the trust has legal
title to 19,600,000 shares of MAS common stock or approximately 77.45% of
the MAS common stock, after giving effect to the exercise of options to
acquire shares of Digital Angel Corporation common stock exercised prior to
the merger. The trust has voting rights with respect to the MAS common stock
until ADS's obligations to IBM Credit Corporation are paid in full. ADS has
retained beneficial ownership of the shares. The trust may be obligated to
liquidate the shares of MAS common stock owned by it for the benefit of IBM
Credit Corporation in the event that ADS fails to make payments to IBM
Credit Corporation beginning on February 28, 2003, or otherwise defaults,
under the IBM credit agreement. As a result, the duration of the trust's
control over MAS following the merger and the identity of any parties which
may acquire control of MAS if and when such sales commence is uncertain.



         Following the merger, the Digital Angel Share Trust owns
approximately 77.45% of the issued and outstanding MAS common stock, after
giving effect to the exercise of options to acquire shares of Digital Angel
Corporation common stock exercised prior to the merger, and has the ability
to control the board of directors and elect the officers of Digital Angel
Corporation. The following individuals were appointed to serve as executive
officers of the registrant following the merger.

Item 2.  Acquisition or Disposition of Assets


         Effective March 27, 2002, the Registrant acquired from ADS the
Advanced Wireless Group of ADS, which consisted of 100% of the outstanding
shares of common stock of Digital Angel Corporation and Timely Technology
Corp., and 85% of the outstanding shares of common stock of Signature
Industries, Limited. Each issued and outstanding share of Digital Angel
common stock held by ADS was converted into 0.9375 shares of MAS common
stock, or 18,750,000 shares of MAS common stock.

         The assets of the Advanced Wireless Group acquired in connection
with the merger included, without limitation, physical property. For the
foreseeable future, the Registrant intends to utilize such assets in
connection with its operations.

         For accounting purposes, the transaction described above will be
accounted for as a reverse acquisition, with the Advanced Wireless Group as
acquirer. The historical financial statements of the Advanced Wireless Group
will become the historical financial statements of the Registrant and the
assets and liabilities of MAS will be accounted for as required under the
purchase method of accounting. The results of operations of MAS will be
included in the financial statements from March 27, 2002, the effective date
of the merger.

         Additional information with respect to the merger is set forth in
the merger agreement which is incorporated herein by reference and attached
hereto as Exhibits 2.1 and 2.2. The Registrant's common stock currently
trades on the American Stock Exchange under the symbol "DOC."


Item 4.  Change in Registrant's Certifying Accountant

         The Registrant and the accounting acquirer currently engage
different independent accountants. The Registrant is evaluating which
accountants will be engaged as the continuing independent accountants. When
this determination is made, the Registrant will file a current report on
