For Immediate Release

             Third Wave, Mitsubishi Announce Japanese Joint Venture
                            for Personalized Medicine

MADISON,  Wis. and TOKYO,  April 5, 2006--Third Wave  Technologies Inc. (Nasdaq:
TWTI) and Mitsubishi  Corporation  today  announced that Third Wave has formed a
joint   venture   with    Mitsubishi   to   accelerate   the   development   and
commercialization of clinical molecular diagnostic products and pharmacogenetics
in Japan and throughout the Asia-Pacific region.

      Third  Wave  Japan now will  accelerate  and  expand  the  development  of
high-value  clinical products for the Japanese  molecular  diagnostic market, in
particular,  and the approval of those products by the Japanese  Pharmaceuticals
and Medical Devices Agency,  or PDMA.  Products for hepatitis B and C viral load
and genotyping,  human papilloma virus, and mycobacterium are in development. In
addition to these  infectious  disease  products,  Third Wave Japan  anticipates
developing  pharmacogenetic  products to improve drug safety and efficacy. Third
Wave will have  worldwide  rights  outside  the  Asia-Pacific  region to any new
technology or product developed by Third Wave Japan.

      Third Wave began to establish its presence in the Japanese clinical market
in 2000.  Third Wave Japan and Mitsubishi  expect to work together to accelerate
the penetration of Invader(R)  products in Asia-Pacific  clinical  laboratories,
particularly  in Japan.  Third  Wave  Japan  expects  to  leverage  Mitsubishi's
strength  and  expertise in the  Asia-Pacific  health care market to help expand
Third Wave's reach in the region.

      The joint venture is being formed through Mitsubishi's minority investment
in Third  Wave  Japan.  Upon  closing  of the  investment,  Mitsubishi  will own
approximately 14% of Third Wave Japan. CSK Holdings Corporation, through its new
subsidiary  CSK Institute for  Sustainability,  Ltd., is also investing and will
own  approximately  3% of Third Wave Japan. The transaction is expected to close
during April 2006.

      Mitsubishi  Corporation is one of Japan's  largest  companies,  generating
more than $160  billion  in  revenues  in 2005.  Mitsubishi  has made  selective
investments  during  the past  several  years as it has  positioned  itself as a
global player in biotechnology. The CSK



Institute of Sustainability is a newly formed subsidiary of CSK Holdings focused
on personalized  medicine.  CSK also has made a number of successful investments
in the biotechnology field in recent years,  focusing on personalized  medicine,
in particular.

      "We are  delighted to be  partnering  with Third Wave in Japan during this
period of rapid change in the Japanese  medical scene,  during which  technology
advancement  is  opening  new  opportunities  in  diagnostics,"  said  Tsunehiko
Yanagihara,  general manager of Mitsubishi  Corporation's Life Sciences Business
Unit.

      "Third Wave and our Invader  chemistry have earned a strong  reputation in
Japan and  elsewhere  in the  region,  and we look  forward to  building  on the
relationship  we have  established  with  Mitsubishi to accelerate our growth in
Asia-Pacific's  clinical  molecular  diagnostics  market," said Kevin T. Conroy,
president and chief  executive  officer of Third Wave.  "The  commitment made by
Mitsubishi and CSK to accelerated commercialization our Invader chemistry to the
clinical market in the region,  demonstrated by their investments in Third Wave,
should be influential as we seek to aggressively expand our market position."

      Third Wave has a long  history of  innovation  in Japan that is founded in
its collaboration with Dr. Yusuke Nakamura of the RIKEN  Institute/University of
Tokyo,  which dates back to 2000. Dr.  Nakamura,  widely  regarded as one of the
world's leading genetic researchers,  led Japan's Millennium Project large-scale
genotyping  initiative and was the principal  contributor  of the  International
HapMap Project. Third Wave supported Dr. Nakamura on these and other efforts. In
addition,   Third  Wave  has  had,  since  2000,  a  product   development   and
commercialization  agreement with BML Inc. of Tokyo, a major clinical  reference
laboratory in Japan.
