Item 5.  Other Events
         ------------

On March 6, 1998 the Company acquired by merger Prisma Acquisition Corp.
("Prisma"), a privately-held company located in Rome, NY, which develops,
manufactures and markets instruments and reagents used by veterinarians to
measure blood chemistry information at the point-of-care. The consideration paid
to the stockholders of Prisma was a $1,000,000 convertible note, 458,000 newly
issued and unregistered shares of the Company's common stock and the issuance of
options to purchase 157,000 shares of the Company's common stock in replacement
of Prisma's outstanding stock options. The 458,000 shares and 157,000 stock
options numbers were calculated by dividing $2,000,000 by $3.25, which was the
average closing price of Synbiotics' common stock for the thirty trading days
prior to March 6, 1998.

The convertible note (which was issued to only one of Prisma's stockholders) is
due March 5, 1999, bears interest at the rate of 5% per year and is unsecured.
The note is convertible at any time, at the option of the Company, into a number
of unregistered shares of the Company's common stock equal to the outstanding
principal and accrued interest divided by the average closing price of the
Company's common stock for the thirty trading days immediately prior to the
conversion. The note is subordinate to the Company's notes payable to Banque
Paribas, which were issued in conjunction with the July, 1997 acquisition of the
veterinary diagnostics business of Rhone-Merieux, S.A.S.

All of the assets acquired by the Company were used and will continue to be used
to operate the instrument and reagent  business activities described above.
