EMPLOYEE STOCK PURCHASE AND SAVINGS PLAN (Full title of the plan) MERCK & CO., INC. P.O. BOX 100 WHITEHOUSE STATION, NEW JERSEY 08889-0100 (Name of issuer of the securities held pursuant to the plan and the address of its principal executive office) 2 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To Merck & Co., Inc.: We have audited the accompanying statements of net assets available for benefits of the Merck & Co., Inc. Employee Stock Purchase and Savings Plan as of December 31, 1993 and 1992, and the related statement of changes in net assets available for benefits for the year ended December 31, 1993. These financial statements and the schedules referred to below are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements and schedules 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 net assets available for benefits of the Plan as of December 31, 1993 and 1992, and the changes in its net assets available for benefits for the year ended December 31, 1993, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes and reportable transactions are presented for purposes 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 audit 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.
