      CHIRON PLANS TO CONDUCT EXCHANGE OFFER WITH HOLDERS OF ITS EXISTING 1.90%
                          CONVERTIBLE SUBORDINATED NOTES

EMERYVILLE, CA, April 6, 2000 -- Chiron Corp (NASDAQ: CHIR) announced today
that it has filed a registration statement with the Securities and Exchange
Commission to register $243.8 million of new convertible subordinated notes
with a seven year maturity date, which will be offered in exchange for its
existing 1.90% Convertible Subordinated Notes due November 17, 2000.  The
conversion premium and coupon rate associated with the new notes will be set
when the exchange offer commences following effectiveness of the registration
statement.

This exchange offer is intended to preserve existing debt/equity ratios,
extend the maturity of a comparable amount of indebtedness, and increase the
conversion price, thereby decreasing the amount of equity issuable upon
conversion as compared to the existing notes.  The specific conversion price
of the new notes will be established based on the average closing price of
Chiron common shares for the five business days preceding the second trading
day prior to the expiration of the tender offer.  In addition to the new
notes current noteholders will receive a cash payment, equal to the
difference between the value of the existing notes and the exchanged notes,
as more fully described in the registration statement.

Consummation of the exchange offer will be conditioned on receipt of at least
75 percent of the 1.90% Convertible Subordinated Notes being validly
tendered, and upon a minimum and maximum stock price which will be set at
transaction launch following effectiveness of the registration statement.

A prospectus for the exchange offer will be available when the registration
statement becomes effective. The new securities may not be exchanged nor may
offers to exchange be accepted prior to the time the registration statement
becomes effective. For more information, holders of the 1.90% Convertible
Subordinated Notes may contact Georgeson Shareholder Communications Inc. at
17th State Street, 10th Floor, New York, NY 10004, or via telephone at
800-223-2064.

Goldman, Sachs & Co. will act as the dealer manager to solicit exchanges.
State Street Bank and Trust Co. of California, N.A. will act as exchange
agent.  Georgeson Shareholder Communications Inc. will act as the information
agent.
