Millipore Conference Call, January 27, 2005
Fourth Quarter and Year-End Results

Forward-looking statements/risk factors
In order to take advantage of the safe harbor provisions of the private securities litigation reform act of 1995, you should understand that we will be making forward-looking statements in this conference. These statements involve a number of risks and uncertainties, all of which are set forth in detail in our annual report on form 10-K, subsequent quarterly reports on form 10-Q, and our other SEC filings. We assume no obligation to update any forward-looking statement based on new information, future events or any other reason.

Regulation G: Use of non-GAAP financial measures
In addition to analyzing U.S. GAAP financial results, management also analyzes “non-GAAP” and “pro forma” financial measures as we believe these measures may allow for a better understanding of the underlying business trends.
“Constant currency” is a non-GAAP measure whereby foreign currency balances are translated, in all periods presented, at Millipore’s predetermined budgeted exchange rates for 2004, thus excluding the impact of fluctuations in the actual foreign currency rates.
Pro forma basis financial results reflect U.S. GAAP results, translated at actual rates of exchange and adjusted for unusual or non-operating items.
