of Millipore Corporation (Millipore or the Corporation).

1. Deferred Amounts. Millipore will establish in your name a book
reserve (the Deferred Compensation Account). Provided this letter is executed and received on or before
{[insert date 30 days from date elected as a Director]},during your service as a Director, Millipore
will credit your Deferred Compensation Account on a quarterly basis, on the first day of January, April, July, and October of each year, commencing with the quarter beginning
{1 , 20}, for the following amounts, which are annualized:



| | (a) | An amount equal to % of the annual retainer payable on the date of the Annual Meeting of Stockholders.
| | --- | ------------------------------------------------------------------------------------------------------



| | (b) | An amount equal to % of all fees which would otherwise be payable to you in consideration of your
attendance at any and all meetings of the Board of Directors of Millipore or any Committee thereof (regular or special on which you serve).
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | % of any and all retainers to which you may in the future be entitled should you service as a Chairman
of a Committee of the Board of Directors of Millipore.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------

2. Interest. Until distribution, interest will be earned on the amount in your
Deferred Compensation Account at the rate Millipore would pay on a senior 10-year Corporate note given the Corporations debt rating at the time of calculation. If Millipore does not have a debt rating, the rate will be its marginal 10-year
senior borrowing rate. The interest rate will be adjusted once a year in January.

3. Title to the Account. Title to and beneficial ownership of the
Deferred Compensation Account shall at all times remain in the Corporation and you and your designated beneficiary shall not have any proprietary interest therein. Your interest in your Deferred Compensation Account may not be assigned, pledged or
hypothecated.

4. Form of Payment. Subject to certain exceptions noted below, payments will be made to you in ten (10) annual installments as
described below.

5. Time of Payment. The amount credited to your Deferred Compensation Account will be paid to you in cash as follows:



| | (a) | Upon retirement from the Board, the installments will be paid on January 1stof each year starting with the year subsequent to retirement.

term as a Board member without renewal or intent to renew.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii. | The amount of each annual cash installment paid on January 1stshall be equal to the Deferred Compensation Account balance as of the immediately preceding December 31stdivided by the number of installments remaining to be made. (For example, if the account balance on December 31stprior to the first installment payment date is $100,000, the first installment amount is $10,000 (i.e., $100,000/10 = $10,000). In the following year, if the account balance on December 31stprior to the second installment payment date is $95,000, the second installment amount is $10,555 (i.e., $95,000/9 = $10,555).)
