These financial statements and the schedule referred to below are the responsibility of the Plan administrator. Our responsibility is to express an opinion on these financial statements and the schedule based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. 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 net assets available for benefits of the Plan as of December 31, 2000 and 1999, and the changes in its net assets available for benefits for the year ended December 31, 2000, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for purposes of additional analysis and is not a required part of the basic financial statements but is 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 schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

More complete information regarding the Plan's provisions may be found in the Plan document. GENERAL Effective January 1, 1989, Medco Containment Services, Inc., which changed its name and corporate structure to Merck-Medco Managed Care, L.L.C. (the "Company"), effective January 1, 1997, established the Plan under the provisions of Section 401(a) of the Internal Revenue Code ("IRC"), which includes a qualified cash or defined arrangement as described in Section 401(k) of the IRC, for the benefit of eligible employees of the Company. The Plan is a defined contribution plan covering substantially all employees of the Company and certain subsidiaries, other than certain employees subject to collective bargaining agreements, who have completed one year of service and attained the age of twenty-one. Participation in the Plan is voluntary. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan was amended as a result of the merger, effective November 18, 1993, by and between the Company and a subsidiary of Merck & Co., Inc. ("Merck"). The amendment provided participants with an option to invest all or part of their contributions in the common stock of Merck. Effective January 1, 1998, the Plan was amended to reflect various statutory changes and to provide participants the ability to direct the investment of Company matching contributions in any of the available investment options. The Plan is administered by the Employee Benefits Committee, which is appointed by the Board of Managers of the Company. All costs of administering the Plan are borne by the Company. CONTRIBUTIONS Each year, participants may contribute an amount up to 15% of base compensation, as defined by the Plan (up to 10% if a highly compensated employee as defined by the IRC) subject to certain limitations under the IRC. Participants direct the investment of their contributions into various investment options offered by the Plan, with a minimum investment of 1% in any investment medium. Fidelity Management Trust Company ("Fidelity") is the trustee of the Plan. As of December 31, 2000, the Plan offered 15 mutual funds and the Merck Common Stock Fund. Effective February 1, 2001, the Plan offers 22 investment options: 21 mutual funds and the Merck Common Stock Fund. The Company matches 100% of employee contributions for the first 3% of base compensation deferred and 50% of employee contributions for the next 3% deferred. Participants direct the investment of all Company matching contributions in any of the available investment options. 4 8 MERCK-MEDCO MANAGED CARE 401(k) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS ---- (Continued) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and the Company's matching contribution and allocation of Plan earnings. Allocation is based on participants' account balances, as defined in the Plan document. VESTING Participants are vested immediately in their contributions plus actual earnings thereon. Participants with an employment commencement date before January 1, 1992 became 100% vested on January 1, 1999. Participants with an employment commencement date on or after January 1, 1992 become vested in Company contributions as follows: Years of Service % Vested ---------------- -------- Less than 2 years 0% 2 years but less than 3 25% 3 years but less than 4 50% 4 years but less than 5 75% 5 years or more 100% At December 31, 2000, forfeited nonvested accounts totaled $1,805,382. These accounts will be used to reduce future Company contributions. PARTICIPANT LOANS Participants may borrow from their account balances with interest charged at the prime rate plus 1%. Loan terms range from one to five years or up to thirty years for the purchase of a primary residence. The minimum loan is $1,000 and the maximum loan is the lesser of $50,000 less the highest outstanding loan balance during the one year period prior to the new loan application date, or 50% of the participant's vested account balance less any current outstanding loan balance. PAYMENT OF BENEFITS In-service and termination distributions are made throughout the year in accordance with applicable Plan provisions. 5 9 MERCK-MEDCO MANAGED CARE 401(k) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS ---- (Continued) (2) SUMMARY OF ACCOUNTING POLICIES USE OF ESTIMATES The financial statements are prepared in conformity with accounting principles generally accepted in the United States and, accordingly, include amounts that are based on management's best estimates and judgments. Actual results could differ from these estimates. INVESTMENT VALUATION AND INCOME RECOGNITION The financial statements of the Plan have been prepared on the accrual basis of accounting. The investments of the Plan are stated at quoted market value. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Purchases and sales of securities are recorded on a trade-date basis. Dividend income is recorded on the ex-dividend date. The net appreciation (depreciation) in market value of investments is based on the beginning of the year market value or value at the time of purchase during the year and is included in the statement of changes in net assets available for benefits. RISKS AND UNCERTAINTIES The Plan provides for various investment options in investment securities. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statement of net assets available for benefits. (3) INVESTMENTS The following presents investments that represent 5 percent or more of the Plan's net assets as of year-end: December 31, -------------------------------- 2000 1999 ------------ ------------ Merck Common Stock Fund, 7,530,475 and 8,514,937 units, respectively $240,646,254 $195,219,801 T. Rowe Price Blue Chip Growth Fund, 1,495,699 and 1,317,333 units, respectively $ 50,629,405 $ 47,871,865 Fidelity Retirement Money Market Fund, 31,516,490 and 17,498,784 units, respectively $ 31,516,490 $ 17,498,784 6 10 MERCK-MEDCO MANAGED CARE 401(k) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS ---- (Continued) During 2000, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value by $49,306,346 as follows: Mutual Funds $(20,365,561) Merck Common Stock Fund 69,671,907 ------------ $ 49,306,346 ============ (4) NONPARTICIPANT-DIRECTED INVESTMENTS The Plan does not have nonparticipant-directed investments. (5) RELATED-PARTY TRANSACTIONS Certain Plan investments are shares of mutual funds managed by Fidelity. Because Fidelity is the trustee, these transactions qualify as party-in-interest transactions. Merck & Co., Inc. is a party-in-interest to the Plan under the definition provided in Section 3(14) of ERISA. Therefore, Merck Common Stock Fund transactions qualify as party-in-interest transactions. All party-in-interest transactions are set forth on the attached schedule. (6) PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become fully vested in their account balances. (7) TAX STATUS The trust established under the Plan is qualified under the IRC as exempt from Federal income taxes and the Plan received a favorable determination letter from the Internal Revenue Service ("IRS") on June 26, 1992. Prior to December 31, 1994, the Plan was amended to meet certain requirements of the Tax Reform Act of 1986. The Plan was restated as of January 1, 1998. The Plan administrator and legal counsel are of the opinion that the Plan meets the IRS requirements and, therefore, the trust continues to be tax exempt. As a result, no provision for income taxes has been made. Prior to December 31, 2001, the Employee Benefits Committee intends to review the Plan and will amend it, if necessary, to meet certain requirements of recent tax code revisions. (8) PROHIBITED TRANSACTIONS There were no prohibited transactions during 2000. 7 11 MERCK-MEDCO MANAGED CARE 401(k) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS ---- (Continued) (9) OTHER MATTERS: Net reallocations in 2000 of $5,862,360 primarily consist of $5,610,248 for employees who transferred into the Plan from ProVantage Health Services, Inc., which was acquired by the Company in June 2000. In addition, ($4,964) was transferred between the Plan and the Merck & Co., Inc. Employee Savings and Security Plan for the employees who were transferred to Merck during 2000. The remaining $257,076 relates to miscellaneous net transfers. 8 12 Schedule H EIN: 22-3461740 Plan No.: 003 MERCK-MEDCO MANAGED CARE 401 (k) SAVINGS PLAN LINE 4i - SCHEDULE OF ASSETS HELD FOR INVESTMENT PURPOSES AS OF DECEMBER 31, 2000 (b) Identity of Issue, Borrower, (c) Description of Investment Including Maturity Date, (a) Lessor or Similar Party Rate of Interest, Collateral, Par or Maturity Value (d) Cost (e) Current Value ---- -------------------------------- ------------------------------------------------------ ------------- ----------------- * Merck & Co., Inc.
