Approach
Call of Special
Meeting
UPEK will solicit AuthenTec
stockholders to call a special
meeting of stockholders
-
10% of AuthenTec
stockholders must deliver “agent
designations”
in order to call a special meeting
At the special meeting (if called), UPEK will seek to
remove all incumbent AuthenTec
directors and elect a
new slate of directors that UPEK believes would be open
to considering the merger proposal
Annual Meeting
UPEK is also going to nominate an alternative slate of 6
directors at AuthenTec’s
upcoming 2010 annual
stockholders meeting
-
UPEK’s
nominees are:  Vincent F. Titolo, Dr. Randall
C. Fowler, Gary Martell, Robert N. Blair, Keith R.
Lobo and Anthony Maher
The nominees have substantial industry experience
Open to Negotiated
Transaction

merger proposal

The Current Situation for AuthenTec
Stockholders
AuthenTec’s
stock has
decreased dramatically since
IPO.  Stockholder value has
similarly declined.
While the economic downturn
has hurt everyone, technology
stocks have recovered to their
original value since the
AuthenTec’s
IPO, while
AuthenTec’s
market
capitalisation has decreased by
75%.
Most of AuthenTec’s
market
capitalisation is represented by
its cash, not its intrinsic
business.
Given this performance, it is
difficult to attract additional
investors.

Peak market
cap. of ~$450m.
In excess of 17
months with no
improvement.
Tech stocks have
recovered since AUTH
IPO, while AUTH
decreased by 75%.
IPO at ~$300m
market cap.
Reports loss of a 2009
design-in opportunity at a
‘significant PC customer.’
Even a new Chairman
has not meaningfully
improved stock.
AUTH is not a very liquid stock, making it
challenging to attract additional investors.


What UPEK Brings to the Combination

that has been won from AuthenTec. UPEK is
also currently shipping

wireless OEMs.
Diversification of the business via strong industrial offerings serving
