THIRD WAVE TECHNOLOGIES, INC. 2000 STOCK PLAN</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THIS FIRST AMENDMENT to the Third Wave Technologies, Inc. 2000 Stock Plan (this &#147;<B>First
Amendment</B>&#148;) is effective as of January&nbsp;19, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Board of Directors (the &#147;<B>Board</B>&#148;) of Third Wave Technologies, Inc. (the
&#147;<B>Corporation</B>&#148;) adopted and the stockholders of the Corporation approved the Third Wave
Technologies, Inc. 2000 Stock Plan (the &#147;<B>Plan</B>&#148;);
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS, the Board has determined that it is in the best interest of the Corporation to amend
the Plan to change the definition of &#147;Fair Market Value&#148; thereunder.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW, THEREFORE, the Plan shall be amended as follows:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;The definition of &#147;Fair Market Value&#148; set forth in Section 1(m) shall be deleted in its
entirety and the following substituted in lieu thereof:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 4%">(m) &#147;Fair Market Value&#148; means, as of any date, the value of Common Stock determined
as follows:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 6%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If the Common Stock is listed on any established stock exchange or a
national market system, including without limitation the Nasdaq Global Market or The
Nasdaq Capital Market of The Nasdaq Stock Market, its Fair Market Value shall be the
closing sales price of such stock (or the closing bid, if no sales were reported) as
quoted on such exchange or system on the date of such determination (or the next
market trading day if the date of such determination is not a market trading day),
as reported in the Wall Street Journal or such other source as the Administrator
deems reliable;
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 6%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) If the Common Stock is regularly quoted by a recognized securities dealer
but selling prices are not reported, the Fair Market Value of a Share of Common
Stock shall be the mean between the high bid and low asked prices of the Common
Stock on the date of such determination (or the next market trading day if the date
of such determination is not a market trading day), as reported in the Wall Street
Journal or such other source as the Administrator deems reliable; or
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 6%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) In the absence of an established market for the Common Stock, the Fair
Market Value shall be determined in good faith by the Administrator.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;Except as herein amended, the terms and provisions of the Plan shall remain in full force
and effect as originally adopted and approved.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IN WITNESS WHEREOF, the undersigned hereby certifies that this First Amendment was duly
adopted by the Board on January&nbsp;19, 2007.
