These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial condition of the Millipore Corporation Employees' Participation and Savings Plan as of December 31, 1993 and 1992 and the income and changes in plan equity for the years ended December 31, 1993, 1992 and 1991 in conformity with generally accepted accounting principles. As more fully described in Note F to the financial statements, the Plan changed its method of accounting for distributions payable in the statement of financial condition. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of (1) assets held for investment and (2) reportable transactions are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/Coopers & Lybrand Boston, Massachusetts Coopers & Lybrand June 24, 1994 F-1 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN STATEMENTS OF FINANCIAL CONDITION December 31, 1993 and 1992 1993 Millipore Short-Term Guaranteed Common Income Balanced Income Equity Loan Stock Fund Fund Fund Fund Fund Total Fund Assets Cash $ - $ - $ - $ - $ - $ - $ - Investments, at fair value: Common stock of Millipore Corporation, 84,068 shares with a cost of $2,714,192 3,362,720 - - - - - 3,362,720 Other Investments 15,393 18,976,434 79,065,170 5,082,654 5,580,384 - 108,720,035 Contributions receivable: Participation Plan - - 6,799,572 - - - 6,799,572 Savings Plan: Employee Contribution 40,333 250,987 171,530 75,738 88,336 - 626,924 Employer Contribution 11,715 70,147 50,580 21,778 25,214 - 179,434 Dividends and interest 11,917 57,851 130,109 167 197 - 200,241 Loan repayments receivable 7,881 68,749 51,371 4,223 15,039 5,922,916 6,070,179 Total assets $3,449,959 $19,424,168 $86,268,332 $5,184,560 $5,709,170 $5,922,916 $125,959,105 Liabilities and Plan Equity Accounts payable and accrued expenses $1,050 $6,786 $44,892 $447 $577 $ - $53,752 Total liabilities 1,050 6,786 44,892 447 577 - 53,752 Plan equity 3,448,909 19,417,382 86,223,440 5,184,113 5,708,593 5,922,916 125,905,353 Total liabilities and plan equity $3,449,959 $19,424,168 $86,268,332 $5,184,560 $5,709,170 $5,922,916 $125,959,105 The accompanying notes are an integral part of the financial statements.

F-3 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN Notes to Financial Statements A. Description of the Plan The Millipore Corporation Employees' Participation and Savings Plan (the Plan) covers all U.S. employees who have at least two years continuous service with Millipore Corporation (the Company) and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan includes a profit participation feature (Participation Plan) and a savings plan feature (Savings Plan). The plan has been amended, effective January 1, 1986, to reduce the eligibility requirements for the Savings Plan from two years to six months. Effective April 1, 1989, eligibility for new hires to participate in the Savings Plan was changed to one year. Under the Participation Plan, the Company makes discretionary contributions to the Plan of a percentage of the Company's profits as designated by the Company's Board of Directors. Contributions are allocated to participants' accounts based on participants' compensation during the year for which the contribution is made and are invested in the Balanced Fund. The Participation Plan is integrated with the Retirement Plan for Employees of Millipore Corporation (Retirement Plan), a separate plan, which provides guaranteed retirement income levels to the extent such income levels are not provided by the Participation Plan. Under the Savings Plan, participants may make voluntary contributions of up to 12% of their eligible compensation. Prior to April 1, 1987 all participants with 10 or more years of service would receive a Company match of 25% of their contributions. Participants with less than 10 years of service would receive a Company match of 25% of their contribution up to 6% of their eligible compensation. Effective April 1, 1987, the Company changed its matching contribution policy for participants with 10 or more years of service -- such participants receive a Company match of 50% of their contribution up to 6% of their eligible compensation. Contributions under the Savings Plan and the Company's matching amount may be invested, at the participants election, in the Balanced Fund, the Short-Term Income Fund, the Equity Fund, the Guaranteed Income Fund or the Millipore Common Stock Fund. Participants are generally allowed to borrow from the Plan the amounts contributed by them and the Company's matching amount. F-4 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN Notes to Financial Statements (Continued) A. Description of the Plan (Continued) Borrowings are evidenced by interest bearing promissory notes and are reflected in the Loan Fund net of principal repayments. All interest payments are credited to the participant's account. All contributions, and income earned thereon, under both sections of the Plan are fully and immediately vested. Participants who are 59 1/2 years or older may at any time withdraw amounts contributed by them as well as income earned thereon. In the event of a participant's death, termination or retirement, all amounts contributed to the Plan by, or on behalf of the participant, including income earned thereon, will be distributed in a lump sum to the participant or beneficiary. Participation Plan contributions in such cases and income earned thereon may be transferred to the Retirement Plan for distribution in accordance with its provisions. A detailed description of the Plan is available upon request at the Company's headquarters in Bedford, Massachusetts. B. Summary of Significant Accounting Policies Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. Investment Valuation Money market funds are valued at cost, which approximates fair market value. Mutual funds are recorded at their net asset value, which approximates fair market value. Common stocks are valued at the last reported sales price on the last business day of the year if traded on a national securities exchange or the last reported bid price as of the last business day of the year if traded on the over-the-counter market. Insurance contracts are valued at contract value. Purchases and sales of securities are recorded on a trade date basis. Realized gains and losses on sales of securities are based on average cost. In accordance with the policy of stating investments at fair value, net unrealized appreciation or depreciation for the year is reflected in the statement of income and changes in plan equity. F-5 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN Notes to Financial Statements (Continued) B. Summary of Significant Accounting Policies (Continued) Dividend and Interest Income Dividend income is recorded on the ex-dividend date. Interest income is recorded as earned on an accrual basis. Contributions Contributions from the Company under the Participation Plan are accrued and paid annually based upon a determination by the Board of Directors of the Company in accordance with the provisions of the Plan. Payment of Benefits Benefits are recorded when paid. C. Investment Programs The Plan's assets are invested among five investment funds and a loan fund. The mix of investments within each fund is determined by the trustees of the Plan. Millipore Common Stock Fund: This fund's investments consist primarily of Millipore Common Stock. Short-Term Income Fund: Investments of this fund include fixed income securities of money market funds and mutual funds that are invested solely in United States Treasury Securities. Balanced Fund: Investments of this fund include money market funds, and mutual funds and are intended to provide a mixture of capital growth and income. F-6 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN Notes to financial Statements (Continued) C. Investment Programs (Continued) Guaranteed Income Fund: Investments of this fund include fixed income securities with specific maturity dates and fixed rates of interest. Equity Fund: Investments of this fund include equity mutual funds or convertible bonds. Loan Fund: This fund consists of amounts borrowed by participants less principal repayments. Loans to participants are reflected as an increase in Loan Fund equity and as a decrease in the equity of the investment fund from which the loan was made. Repayments, conversely, reduce loan fund equity and increase the respective investment fund's equity. Interest paid to the Plan on loans to participants is credited to the borrower's account in the investment fund to which repayments are allocated.

Investment Income (Continued) Income earned by each fund, including realized and unrealized gains and losses on investments, is allocated to participants' accounts based on their pro rata share of contributions and income earned thereon. At December 31, 1993, there were 616 employees participating in Millipore Common Stock Fund, 1,493 in the Short-Term Income Fund, 3,029 in the Balanced Fund, 622 in the Guarantee Income Fund, and 701 in the Equity Fund, There were 907 participants with loans outstanding from the Loan Fund at December 31, 1993. Employees are permitted to invest in more than one fund. F. Distributions Payable In July of 1993, the American Institute of Certified Public Accountants issued an audit guide entitled "Audits of Employee Benefit Plans, with conforming changes as of May 1, 1993", (the "Guide"). The provisions of the Guide are effective for plan years beginning after December 15, 1990. The Guide prohibits the recognition, as a liability, of amounts allocated to participants who have withdrawn from the Plan as of year end, but for which disbursement of those funds has not been made by year end, in the statements of financial condition. Disclosure of such amounts, however, is required. Accordingly, the Plan has adopted these provisions effective January 1, 1993. The cumulative effects of the adoption of this provision as of January 1, 1993 were a decrease in terminations and withdrawals payable of $1,838,052 and an increase in net income of $1,838,052 for the year ended December 31, 1993. The following is a reconciliation of plan equity per the financial statements to the Form 5500: 1993 Plan equity per the financial statements $125,905,353 Amounts allocated to withdrawing participants 3,267,379 Net Assets available for benefits per the Form 5500 $122,637,974 The following is a reconciliation of terminations and withdrawals per the financial statements to the Form 5500 for the year ended December 31, 1993: 1993 Terminations and withdrawals per the financial statements $7,327,699 Add: Amounts allocated to withdrawing participants at December 31, 1993 3,267,379 Less: Amounts allocated to withdrawing participants at December 31, 1992 1,838,052 Benefits paid to participants per the Form 5500 $8,757,026 F-11 MILLIPORE CORPORATION EMPLOYEES' PARTICIPATION AND SAVINGS PLAN Notes to Financial Statements (Continued) F. Distributions Payable (Continued) Amounts allocated to withdrawing participants are recorded on the Form 5500 for benefit claims that have been processed and approved for payment prior to December 31 but not yet paid as of that date. G. General Termination Condition While the Company has not expressed any intent to discontinue its contribution under the participation feature of the Plan, it is free to do so at any time under the current provisions of the Plan. In the event of a permanent discontinuance of Company contributions under the participation feature of the Plan, dissolution of the Company, acquisition of the Company by an unaffiliated Company or vote by the Company's Board of Directors to discontinue the Plan, the Plan shall be deemed terminated and each participant shall be entitled to an immediate distribution of his account. H. Tax Status The Internal Revenue Service has determined and informed the Company by a letter dated April 2, 1985, that the Plan is designed in accordance with applicable sections of the Internal Revenue Code (IRC). The plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. Amounts contributed to the Plan by a participant or by the Company on behalf of a participant up to the amount deferrable under the Code are generally not included in the participant's gross income in the year of the contribution. Participants are not subject to federal income tax on income credited to their account nor can they deduct losses charged to their account until distributions are made to them. A participant or beneficiary may, in certain circumstances, defer payment of federal income taxes on all or a portion of distributions from the Plan by transferring all or a portion of the distribution to an individual retirement account or other qualified plan.
