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.

This press release is for informational purposes only and does not
constitute an 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 only pursuant to an offer to exchange
and related materials that Sirona intends to distribute to its option
holders and file with the Securities and Exchange Commission. Option
holders should read carefully the offer to exchange and related
materials because they will contain important information, including the
various terms of, and conditions to, the exchange offer. Option holders
and stockholders will be able to obtain a free copy of the tender offer
statement on Schedule TO, the offer to exchange, and other documents
that Sirona intends to file with the Securities and Exchange Commission
at the Commission’s website at www.sec.gov,
or directly from Sirona using the contact information below. Option
holders are urged to carefully read these materials prior to making any
decision with respect to the exchange offer.
