US HIFU Acquires European Distribution Rights of the Sonablate(R) 500 Medical Device and Ownership of the Sonatherm(R) 600 Medical Device

CHARLOTTE, North Carolina, May 28, 2010 - USHIFU, LLC (US HIFU), a world leader in minimally invasive high
intensity focused ultrasound (HIFU) technologies and manufacturer of the
Sonablate(R) 500 (Sonablate) medical device, announces the acquisition of
certain Misonix (Nasdaq: MSON) HIFU assets and European distribution rights.
In addition, through its transaction with Misonix, US HIFU acquires the
Sonatherm(R) 600 medical device, a laparoscopic HIFU system used to ablate
certain soft tissues.

The acquisition of the Sonatherm 600 is a major step for US HIFU: it
represents the company's first device with FDA clearance for
commercialization in the U.S.

"Our intent has always been to continue building the HIFU device product
pipeline, and acquiring the Sonatherm is a significant milestone in that
process," said US HIFU's chief executive officer Steve Puckett, Jr. "The
device has two FDA 510(k) clearances for soft tissue ablation. Post-market
surveillance trials have already begun in Europe, and we plan to add clinical
sites in the U.S. to study the Sonatherm 600 later this year."

In addition to US HIFU's plans for clinical evaluation of the Sonatherm
600 in Europe and the U.S., its plans for growing the Sonablate HIFU
technology in Europe include rolling out state-of-the-art Sonablate 500
machines; infusing both capital and human resources to significantly increase
access to Sonablate HIFU; expanding the base of European Sonablate users; and
increasing the existing clinical data registry.

Sonablate HIFU for prostate cancer is a minimally invasive, targeted
approach to treating the disease with precision-focused ultrasound energy
that, when delivered, raises the temperature of the tissue in a matter of
seconds, resulting in its destruction. The tissue throughout the prostate is
ablated while structures outside the gland remain unharmed.

Members of US HIFU's management team are making preparations for a
European road show whereby they will showcase the innovative feature upgrades
to the Sonablate by giving a then-versus-now comparison. The team will also
strategize with clinicians to tailor flexible, market-specific roll-out
plans.

"We are confident that this initial push will have a big impact
considering that much of the European user base has been exposed exclusively
to older Sonablate technology, and we have made a number of technical
upgrades," said Puckett. "We also want to convey to the European clinical
community our commitment to substantially increase the monetary and human
resources dedicated to physician training, patient education, technician
support and data collection through our International HIFU Registry."

UK HIFU, one of US HIFU's subsidiaries, will conduct day-to-day European
operations. The first European headquarters will be in the UK, with a
satellite office in Berlin scheduled to open over the next three months. In
collaboration with UK HIFU employees, US HIFU staff will launch and continue
to conduct business operations in Europe to guarantee rapid proliferation of
the technology and physician training.

"This transaction brings Sonablate manufacturing and research and
development together again under one roof-Focus Surgery-allowing for
increased efficiency operationally and an expansion of our HIFU product
portfolio," said Puckett.

Sonablate HIFU is under clinical investigation by the FDA in the U.S. but
approved or authorized and commercially available in more than 30 other
countries. Through International HIFU, one of US HIFU's subsidiaries,
patients and physicians from the U.S. are traveling regularly for the
procedure to locations where it is approved and available, such as Mexico,
Bermuda, the Bahamas and Canada.
