       Item 5.  Other Events.
  
           On March 30, 1999, Fusion Medical Technologies, Inc. (the "Company")
  and BankBoston, N.A. (the "Rights Agent") executed an amendment (the
  "Amendment") to the Preferred Shares Rights Agreement dated October 10, 1997
  between the Company and the Rights Agent (as amended, modified or supplemented
  from time to time, the "Rights Agreement"). Capitalized terms used but not
  defined herein shall have the meaning assigned thereto in the Rights Agreement.
  
           Section 27 of the Rights Agreement provides that prior to the
  Distribution Date, the Company may supplement or amend the Rights Agreement in
  any respect without the consent of the Rights Holders. The State of Wisconsin
  Investment Board ("SWIB") requested the Company to amend the Rights Agreement to
  exclude SWIB from the definition of "Acquiring Person" unless and until such
  time as SWIB becomes the Beneficial Owner of a percentage of Common Shares of
  the Company then outstanding which equals or exceeds 20%. SWIB agreed not to
  seek election or placement of a representative of SWIB on the Company's Board of
  Directors while SWIB is the Beneficial Owner of 15% or more of the outstanding
  Common Shares of the Company. The Company approved the Amendment on March 30,
  1999.
  
           The Amendment provides that SWIB shall not be deemed to be an Acquiring
  Person under the Rights Agreement until SWIB shall have become the Beneficial
  Owner of a percentage of Common Shares then outstanding which equals or exceeds
  the SWIB Percentage.  The SWIB Percentage equals 20% through January 14, 2000.
  However, after January 14, 2000, the SWIB Percentage shall be reduced to (i)
  15%, if SWIB does not beneficially own 15% or more of the Common Shares
  outstanding at the close of business on January 14, 2000, or (ii) if SWIB
  beneficially owns 15% or more of the Common Shares outstanding at the close of
  business on January 14, 2000, the next highest whole percentage in excess of the
  percentage of Common Shares of the Company then outstanding and beneficially
  owned by SWIB, not to exceed 20%.  The definitions of "Distribution Date" and
  "Triggering Event" were also amended to conform to the modifications made to the
  definition of Acquiring Person.
  
           The Amendment to the Rights Agreement, specifying the terms of the
  Rights, is an exhibit hereto, and the Rights Agreement, including the form of
  the Rights Certificate, is incorporated herein by reference. The foregoing
  description of the Rights and the Amendment does not purport to be complete and
  is qualified in its entirety by reference to such exhibits.
