ITEM 5.  OTHER EVENTS.

On January 28, 2002 the Board of Directors of Millipore Corporation declared a
stock dividend of all of the shares of Mykrolis Corporation owned by Millipore.
The dividend will be distributed on February 27, 2002, to Millipore stockholders
of record as of 5:00 p.m. Eastern time on February 13, 2002.  Millipore
currently owns 32,500,000 shares of Mykrolis common stock, which represents
approximately 82.3 percent of the total outstanding common stock of Mykrolis.
The other 17.7 percent of the outstanding common stock of Mykrolis was sold by
Mykrolis in an initial public offering on August 9, 2001.

                      FORWARD LOOKING STATEMENT DISCLAIMER

The matters discussed herein, as well as in future oral and written statements
by management of Mykrolis Corporation that are forward-looking statements, are
based on current management expectations that involve substantial risks and
uncertainties which could cause actual results to differ materially from the
results expressed in, or implied by, these forward-looking statements.  When
used herein or in such statements, the words "anticipate", "believe",
"estimate", "expect", "may", "will", "should" or the negative thereof and
similar expressions as they relate to Mykrolis or its management are intended to
identify such forward-looking statements.  Potential risks and uncertainties
that could affect Mykrolis' future operating results include: further
deterioration in our revenues due to a prolonged downturn in the semiconductor
industry; the loss of or reduction in orders from our key customers, who are
likewise adversely impacted by the downturn in the semiconductor industry and
which account for a large percentage of our sales; delays or disruptions in the
transfer of the production of our products to different manufacturing facilities
pursuant to the separation from Millipore Corporation; increased competition in
our industry resulting in downward pressure on prices and reduced margins;
increased costs associated with building out our business infrastructure in
connection with our separation from Millipore Corporation; and those risks
described under the heading "Risk Factors" in our Registration Statement on Form
S-1 (Reg. No. 333-57182) which was declared effective on August 9, 2001, in our
second and third quarter 10-Q Reports and in our other SEC filings.
