     Third Wave Reports Fourth-Quarter and Full-Year 2005 Financial Results

MADISON,  Wis., Feb. 28, 2006--Third Wave Technologies Inc. (Nasdaq: TWTI) today
reported financial results for the fourth quarter and year ended Dec. 31, 2005.

      Third Wave  reported  total  revenues  of $23.9  million and a net loss of
$22.3 million,  or ($0.54) per diluted share,  for the year ended Dec. 31, 2005,
compared to total  revenues of $46.5 million and a net loss of $1.9 million,  or
($0.05)  per diluted  share,  for the prior year.  The  company  reported  total
revenues of $5.8 million and a net loss of $5.0 million,  or ($0.12) per diluted
share, for the fourth quarter ended Dec. 31, 2005, compared to total revenues of
$8.1 million and a net loss of $4.7 million,  or ($0.12) per diluted share,  for
the same period of 2004.

      The year-over-year  variances in the company's  financial results were due
largely to the previously  announced and  anticipated  decline in  non-recurring
research  revenue,  which  decreased by $23.7  million in 2005,  and to the $6.9
million in  litigation  expense  incurred in 2005 to defend the  company's  core
patents.

      Third Wave reported total clinical  molecular  diagnostic revenue of $15.7
million for the year ended Dec. 31, 2005, an increase from $15.0 million for the
prior year.  U.S.  clinical  molecular  diagnostic  revenue  increased  to $14.5
million, or 18%, during 2005.

      The company  reported  gross  margins of 70% for both the quarter and year
ended  Dec.  31,  2005,  compared  to 72% and 73% for the same  periods of 2004,
respectively.  Total operating expenses were $11.1 million and $47.1 million for
the  quarter  and year ended Dec.  31,  2005,  respectively,  compared  to $13.1
million and $48.9 million for the same periods of 2004.

      Third Wave incurred  significant  litigation expenses during 2005. For the
second  time in two  years,  the  company  successfully  enforced  its  patented
nucleic-acid  detection  methods.  A  federal  jury last  fall  found  that that
Stratagene  Corp.  infringed two key Third Wave patents covering its proprietary
molecular methods. Stratagene recently posted a


$21-million  bond with the court in Third  Wave's name that  secures the damages
and  attorneys'  fees awarded to Third Wave in the  successful  suit.  The court
issued its  decision  last week  awarding  all of Third  Wave's  requested  $4.2
million in attorneys'  fees and costs.  The company has announced that, with the
exception of its dispute  with  Stratagene,  it has resolved its  patent-related
lawsuits and anticipates  significantly lower litigation expenses during 2006 as
a result.

      The  savings  in  litigation  expenses  will  enable  Third Wave to invest
heavily during 2006 in research and development,  and in the clinical trials for
its  human  papilloma  virus,  or HPV,  and  pharmacogenetic  products  that are
necessary for the anticipated submissions of those products to the U.S. Food and
Drug  Administration  (FDA). The current global HPV market is approximately $150
million and is growing at 30-35% a year. The total global market  opportunity is
approximately $1 billion a year. The potential market  opportunity in the United
States alone is more than $500 million.

      The company in late December 2005 paid off a $9.5-million bank note. Third
Wave ended 2005 with cash, cash equivalents and short-term  investments of $38.7
million, compared to $66.7 million at Dec. 31, 2004.

      "Third  Wave will  continue to focus on the growth of the  company's  U.S.
clinical  molecular  diagnostic  revenue  during  2006 and we believe  2005 is a
strong  foundation  for that growth," said Kevin T. Conroy,  president and chief
executive of Third Wave.  "During  2005,  we increased  our  recurring  clinical
customer  base to more than 140, and launched new clinical  products,  including
our FDA-cleared UGT1A1  pharmacogenetic test. Our Invader chemistry also enables
us to capture  recurring-revenue  opportunities in the research and agricultural
markets and we will continue to do so in 2006.

      "Third  Wave's  Invader  chemistry and  outstanding  people give us unique
advantages in the growing nucleic acid testing market," Mr. Conroy said. "We are
committed to making  solid  progress on both  revenues and new product  delivery
during 2006 to maximize shareholder value, which is our top priority."

2006 Outlook

      Third Wave  anticipates  total revenues of $23-25 million,  which includes
increases in clinical  molecular  diagnostic  and Agbio revenue and a decline in
research revenue. The company expects U.S. clinical molecular diagnostic revenue
of $15.5-17.5 million and total clinical molecular  diagnostic revenue of $16-18
million.  Agbio revenue, which is a component of research revenue, will continue
to grow, but total research  revenue will decline to  approximately  $7 million,
due to the  completion  of  research  projects  that  has been  anticipated  and
previously announced.
