<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Waters Corporation to Acquire Environmental Resource Associates, Inc. (ERA), Leader in
Environmental Laboratory Proficiency Testing</B>
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Milford, MA, November&nbsp;20, 2006 &#151; Waters Corporation (NYSE: WAT) announced today it has entered
into an agreement to acquire all the outstanding capital stock of ERA, a privately held company
located in Arvada, Colorado, U.S.A., for an undisclosed amount. The transaction is expected to be
complete before the end of 2006. Current annual revenues for ERA are approximately $17&nbsp;million and
the acquisition is expected to be neutral to Waters Corporation&#146;s (&#147;the Company&#148;) earnings in 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Commenting on the planned acquisition, Ian King, Vice President of Chemical Operations at Waters
said, &#147;Environmental testing is a significant growth market for the Company and the addition of ERA
improves our access to this customer base. ERA is recognized as a market leader in laboratory
proficiency testing with highly dedicated and professional management and talented employees.
Combining the strengths of the Company&#146;s analytical technologies with ERA&#146;s leading testing
services will create new business opportunities, especially in emerging geographies where method
standardization and calibration are increasingly in higher demand.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Dr.&nbsp;Carl Craig, ERA Vice President of Sales and Marketing, commented, &#147;We&#146;re very excited with the
prospect of expanding ERA&#146;s international business while continuing to build upon our leadership
position in the U.S.A. in the environmental proficiency testing and pharmaceutical reference
materials markets.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Waters Corporation holds worldwide leading positions in three complementary analytical technologies
&#151; liquid chromatography, mass spectrometry and thermal analysis. These markets account for
approximately $5&nbsp;billion of the overall $20 &#151; $25&nbsp;billion analytical instrument market.

<DIV style="font-family: 'Times New Roman',Times,serif">
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Certain statements contained herein are forward looking. Many factors could cause actual results
to differ from these statements, including delays in product introductions, loss of market share
through competition, introduction of competing products by other companies, pressures on prices
from competitors and/or customers, regulatory obstacles to new product introductions, lack of
acceptance of new products, changes in the healthcare market and the pharmaceutical industry,
changes in distribution of the Company&#146;s products, and foreign exchange fluctuations. Such factors
and others are discussed more fully in the section entitled &#147;Risk Factors&#148; of the Company&#146;s annual
report on Form&nbsp;10K for the year ended December&nbsp;31, 2005 and quarterly report on Form&nbsp;10Q for the
period ended September&nbsp;30, 2006, as filed with the Securities and Exchange Commission, which &#147;Risk
Factors&#148; discussion is incorporated by reference in this release.
