The Carlyle Group, Partnering with J.H. Whitney & Co., Leads Acquisition of Authentix, Inc.

Global private equity firm The Carlyle Group today announced that

along with private equity firm J.H. Whitney & Co., a group of existing
investors that include Manti Resources, Inc., and Authentix´ existing
management team, it has acquired Authentix, Inc., a company that
develops and delivers an array of authentication and brand protection
solutions in the banknote, consumer, medical device, oil and gas and
pharmaceutical industries, as well as excise tax recovery solutions
for national and state governments. The transaction closed on April
18, 2008. Financial terms were not disclosed.

A pioneer in the rapidly growing authentication industry

Authentix develops nanoscale-engineered markers, opto-electronic and
nanophotonic detection devices and software that help its clients
ensure the authenticity, integrity and safety of their products. Over
the past five years, Authentix has recovered more than $5 billion in
lost revenues for its clients, which include Fortune 500 companies and
national governments. Authentix currently provides authentication
services in 18 countries on five continents.

"Focused on industries that are most susceptible to losses from
the counterfeiting of their products, Authentix will continue to
capitalize on the authentication market, which is projected to triple
by 2011," said Steve Bailey, Managing Director, The Carlyle Group. "We
are excited to work with Authentix´ seasoned management team and
talented employee base and to continue to invest in research and
development at a rate commensurate to the growing concern about the
rise of counterfeiting, smuggling and grey market diversion."

"This transaction will enable Authentix to tap into Carlyle´s
global network and expertise and significantly strengthen our
international business development activities," said David Moxam

Chairman and CEO, Authentix. "Additionally, we are excited to extend
our capital base and accelerate our acquisition strategy to better
serve our existing and future clients across all industries. As the
dynamics of global counterfeiting continue to evolve, this investment
affirms our commitment to the use of advanced and innovative
nanotechnology, device and software platforms for brand integrity and
excise tax collection programs."

"Authentix´ unique portfolio of technologies and its
solutions-based approach has ensured the company is a trusted partner
to corporations and governments around the world," said Carlyle Senior
Advisor, Charles Rossotti, who from 1997 to 2002 served as
Commissioner of Internal Revenue Service. "In particular, Authentix´
Excise Tax Recovery Programs provide government authorities with the
ability to effectively authenticate and track goods to ensure tax
revenues are optimized rather than lost altogether, a major problem

for example, in tobacco and oil and gas industries. I look forward to
working with the Authentix team to further expand the company´s global
client base."

MHT Securities, a wholly owned subsidiary of MHT Partners, which
focuses on merger and acquisition advisory for tech-enabled growth
companies, was the exclusive advisor to Authentix in this transaction.

Authentix´ solutions are built upon three key components:
authentication, recognition and data management. Depending on a
particular client´s needs, products are marked with authenticating
forensic features that range from nanoscale markers embedded in
packaging materials to molecular markers that can be incorporated into
the product itself (ranging from fuels to pharmaceuticals). Authentix
develops a wide range of opto-electronic devices that are used to test
for these proprietary markers. These devices recognize the in-product
and on-package markers determining if the product is authentic

counterfeit or diluted. Data retrieved from product sampling via
Authentix´ opto-electronic devices can be aggregated and used to
create real-time reports for clients. This authentication and tracking
data, for example, highlights geographical problem domains, identifies
compromises in supply chain integrity, etc. This valuable information
and analyses enable clients to take appropriate remedial action.
