Ambulance of Modesto, Inc. and Intensive Care Ambulance, Inc. (collectively, the
"Disappearing Corporations") merged with and into the Surviving Corporation.
Said document was filed with the Office of the Secretary of State of California
on December 31, 1995.

     3. Paragraph 7 of the Agreement of Merger, as corrected, shall read in its
entirety as follows:

          "7. All of the issued and outstanding shares of each Disappearing
          Corporation shall, upon the effective date of the merger, be canceled
          without consideration. The issued shares of the Surviving Corporation
          shall not be converted or exchanged in any manner or any consideration
          be paid therefor, but each said share which is issued as of the
          effective date of the merger shall continue to represent one issued
          share of the Surviving Corporation."

     4. The foregoing correction of the Agreement of Merger does not change any
resolution duly approved by the board of directors or shareholders of the
Surviving Corporation or the Disappearing Corporations.

     I further declare under penalty of perjury under the laws of the State of
California that the matters set forth in this Certificate are true and correct
and of my own knowledge.
