                ENTEGRIS MICROELECTRONICS GROUP SHIFTS TO DIRECT
 SALES AND DISTRIBUTION SYSTEM IN EUROPE AND ASIA; FLUID HANDLING GROUP EXTENDS
                       DISTRIBUTION AGREEMENT WITH METRON

  Company expects to exceed second quarter financial performance expectations,
                           excluding one-time charge

     CHASKA, Minn., March 1, 2001-- Entegris, Inc. (Nasdaq: ENTG), the materials
integrity management company, today announced that it will shift sales
responsibility for its microelectronics group products from Metron Technology
N.V. to a direct sales and distribution system beginning April 1, 2001 in Europe
and May 1, 2001 in Asia. The company also announced it has extended its contract
with Metron to distribute its fluid handling group's product line in all regions
currently covered until at least August 31, 2005.

"As the market changes, this is an important step for our microelectronics group
to ensure we stay as close as possible to our customers," commented Jim
Dauwalter, Entegris' CEO. "Our ongoing goal is to provide the most efficient and
effective means of protecting and transporting their critical materials.
Utilizing our worldwide infrastructure, we believe this change will aid us to
better anticipate customer needs and react quickly in support of rapidly
changing market conditions."

"We are pleased Metron is working closely with us during the transition period,"
Dauwalter continued. "Their continued support is facilitating a smooth
transition for our employees and customers worldwide. In addition, Metron will
continue to be an integral part of our worldwide sales and distribution network
for the fluid handling group. They have proven to be a valuable business partner
and have served Entegris well by helping to drive record revenue growth for the
fluid handling group."

                                     -more-


Under the terms of the transition agreement, Entegris will transfer to Metron
1.125 million shares of its Metron stock and make cash payments of $1.75 million
over a 15-month period, for the early termination of the microelectronics group
product distribution agreement. In addition, Entegris has agreed to buy back
approximately $2.5 million worth of existing microelectronics group product
inventory from Metron pending inspection and approvals.

Related to the transfer of Metron shares, cash payments and other costs
associated with the agreement, Entegris expects to take a one-time pre-tax
charge of approximately $8 million or $0.07 cents earnings per share (EPS)
during the second quarter ending February 24, 2001. The company expects to
exceed its previous second quarter 2001 sales financial guidance of
approximately $102 million.

"By leveraging our current infrastructure, we feel that the move will have a
positive impact on our financial performance after the transition period and
provide us with a more direct and close relationship with our customers," said
John Villas, Entegris' CFO.

The agreements will be filed with the Securities and Exchange Commission on Form
8K.
