Item 5.  Other Events.

                  On November 1, 1998, Sofamor Danek Group, Inc. (the "Company")
entered into an Agreement and Plan of Merger (the "Merger Agreement") with
Medtronic, Inc., a Minnesota corporation ("Parent"), and MSD Merger Corp., an
Indiana corporation and wholly owned subsidiary of Parent ("Merger Subsidiary").

                  Subject to the terms and conditions of the Merger Agreement,
Merger Subsidiary will be merged with and into the Company (the "Merger") at the
effective time of the Merger and the Company will become a wholly owned
subsidiary of Parent. At the effective time of the Merger, then outstanding
shares of common stock, no par value, of the Company ("Company Common Stock"),
other than shares of Company Common Stock to be canceled in accordance with the
Merger Agreement, will be converted into the right to receive a number of shares
(carried out to five decimal places and rounded up if the sixth decimal place is
5 or greater) (the "Conversion Ratio") of common stock, par value $.10 per
share, of Parent ("Parent Common Stock"), based on the average (rounded to the
nearest full cent, with the cents rounded up if the third decimal place is 5 or
more) of the daily closing sale prices of a share of Parent Common Stock as
reported on the New York Stock Exchange ("NYSE") Composite Tape, as reported in
the Wall Street Journal (the "Parent Average Stock Price"), for the fifteen
consecutive NYSE trading days ending on and including the NYSE trading day that
is two NYSE trading days prior to the meeting of shareholders of the Company
that will be called to vote on the Merger (the "Determination Period"),
determined as follows.

         (i)      if the Parent Average Stock Price for the Determination Period
                  is greater than $56.97 and less than $69.63, then the
                  Conversion Ratio shall equal $115 divided by the Parent
                  Average Stock Price for the Determination Period;
         (ii)     if the Parent Average Stock Price for the Determination Period
                  is equal to or less than $56.97, then the Conversion Ratio
                  shall equal 2.01861; or
         (iii)    if the Parent Average Stock Price for the Determination Period
                  is equal to or greater than $69.63, then the Conversion Ratio
                  shall equal 1.65159.

                  The Merger is subject to approval by the shareholders of the
Company, regulatory approvals and other customary closing conditions.

                  Also on November 1, 1998, the Company entered into a Stock
Option Agreement with Parent (the "Stock Option Agreement") pursuant to which
the Company granted an option to Parent to purchase up to 5,366,478 shares of
Company Common Stock at a price of $115 per share upon the occurrence of certain
events related to termination of the Merger Agreement.
