Sirona Announces Fair Value Option Exchange Offer

LONG ISLAND CITY, N.Y.--(Business Wire)--
Sirona (Nasdaq: SIRO), a leading global manufacturer of technologically
advanced, high quality dental equipment, today announced that its Board of
Directors has authorized a fair value option exchange program for the Company’s
2006 Equity Incentive Plan. This exchange program, which is only available to
employees and eligible consultants, is expected to provide additional incentive
and retention value. 

Under the terms of the exchange, participants will be able to tender options
which have significantly higher exercise prices than the current market value
and in return obtain a lower number of newly granted options. The exercise price
of the new options will be the closing price of Sirona common stock on the
NASDAQ Global Select Market on the exchange date, the date on which this offer
expires. The option exchange program is designed so that the current fair value
of the options surrendered is equal to the fair value of the replacement
options, and the exchange offer will not result in additional expense. The
replacement options will have an additional year of vesting as compared to the
surrendered options. Approximately 1.1 million options are eligible for exchange
under the offer.

offer to buy or the solicitation of an offer to sell shares of Sirona common
stock or options to purchase Sirona common stock.The exchange offer will be made
