Deregistration
_____________________
This Registration Statement registered 152,565 shares of the Common Stock
of Synbiotics Corporation (the "Company"). These shares were offered pursuant
to Company's 1998 Stock Option Plan (the "Option Plan"). 140,899 shares have
been issued under the Option Plan. The remaining 11,666 stock options
outstanding under the Option Plan have been rolled into the Company's 1995 Stock
Option/Stock Issuance Plan, separately registered under a Form S-8 Registration
Statement filed with respect to the 1995 Stock Option/Stock Issuance Plan.
A new Form S-8 Registration Statement was filed today with respect to an
increase in the number of shares covered by the 1995 Stock Option/Stock Issuance
Plan. For purposes of calculating a reduced registration fee thereunder, the
11,666 "unused" shares under this Registration Statement were "transferred over"
to the new Form S-8 Registration Statement.
Accordingly, the Company hereby deregisters 11,666 shares of the Common
Stock originally covered by the Registration Statement.
