2 REQUIRED INFORMATION (as required by items no. 1 thru 3) INDEX Independent Accountants' Report Financial Statements: Statements of Net Assets Available for Plan Benefits as of December 31, 1998 and 1997 Statements of Changes in Net Assets Available for Plan Benefits for the years ended December 31, 1998 and December 31, 1997 Notes to Financial Statements Supplemental Schedules: Schedule I - Item 27a - Schedule of Assets held for investment purposes as of December 31, 1998. Schedule II - Item 27d - Schedule of Reportable Transactions for the year ended December 31, 1998.

3 Independent Accountants' Report To the Participants and Administrator of Dover Corporation Retirement Savings Plan: In our opinion, the accompanying statements of net assets available for plan benefits and the related statements of changes in net assets available for plan benefits present fairly, in all material respects, the net assets available for plan benefits of the Dover Corporation Retirement Savings Plan (the "Plan") at December 31, 1998 and 1997, and the changes in net assets available for plan benefits for the years ended December 31, 1998 and 1997 in conformity with generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above. Our audits were conducted 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 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 fund information in the statements of net assets available for plan benefits and the statement of changes in net assets available for plan benefits is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for plan benefits of each fund. These supplemental schedules and fund information are the responsibility of the Plan's management. The supplemental schedules and fund information 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.

8 (1) Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying statements, prepared on the accrual basis of accounting, present the net assets available for Plan benefits and changes in net assets available for Plan benefits for the Dover Corporation Retirement Savings Plan (the "Plan"). (b) Management of Trust Funds American Express Financial Advisors (the "Trustee") has been granted discretionary authority to purchase and sell securities. The Trustee maintains investment funds as follows: - The Dover Corporation Pooled Stock Account (Stock Fund) is authorized to invest in Dover Corporation common stock and money market funds. - The American Express Trust Income Fund II (Income Fund) is authorized to invest primarily in insurance and bank investment contracts. About 90% of the investments are made in stable contracts; the remaining 10% are invested in high-quality money market securities. - The IDS Stock Fund (Equity Fund) is authorized to invest mainly in U.S. common stocks and bonds. This is a medium risk fund with medium long-term return potential. - The IDS Mutual Fund (Balanced Fund) is authorized to invest mainly in common and preferred stocks and bonds while it also makes investments in securities of foreign issuers, cash, short-term corporate notes and repurchase agreements, and stock index futures contracts and options. - The IDS New Dimensions Fund (Growth Fund) is authorized to invest mainly in U.S. common stocks and may also invest in securities of foreign issuers, cash, short-term corporate notes and repurchase agreements, and stock index futures contracts and options. This fund has a higher long-term return potential. - The Templeton Foreign Fund is authorized to invest primarily in stocks and debt obligations of companies and governments outside the United States with the objective of obtaining long-term capital growth. - The Aim Constellation Fund is authorized to invest primarily in common stocks of medium-sized and smaller emerging growth companies with the objective of obtaining capital growth. - The American Express Trust Long-Term Horizon Fund is authorized to invest in other collective investment funds to create a diversified portfolio with an aggressive risk profile appropriate for individuals with long-term time horizons. - The American Express Trust Medium-Term Horizon Fund is authorized to invest in other collective investment funds to create a diversified portfolio with a moderately conservative risk profile appropriate for individuals with medium-term time horizons - The American Express Trust Short-Term Horizon Fund is authorized to invest in other collective investment funds to create a diversified portfolio with a conservative risk profile appropriate for individuals with short-term time horizons.

9 The Plan Administrator may delegate the management of the Plan's assets to another investment manager if it deems it advisable in the future. Funds temporarily awaiting investment are placed in a short-term investment fund of the Trustee where they earn the prevailing market rate of interest. (c) Investments Investments in securities are carried by the Plan at fair values, which are determined by the Trustee, as follows: - Common stock - quotations obtained from National Securities Exchanges; and fixed income and short-term securities (U.S. government obligations, commercial paper, corporate bonds) - stated at market values based upon market quotations obtained from published sources. - Purchases and sales of investment securities are reflected on a trade-date basis. Gains and losses on sales of investment securities are determined on the average cost method. - Dividend income is recorded on the ex-dividend date. Income from other investments is recorded as earned. (d) Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates (e) Risks and Uncertainties The Plan provides for various investment options in any combination of stocks, bonds, mutual funds, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is as least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for plan benefits and the statement of changes in net assets available for plan benefits. (f) Other The Plan presents in the Statement of Changes in Net Assets Available for Plan Benefits, the net appreciation (depreciation) in the fair value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Participant loans are valued at cost, which approximates fair value.

10 2) The Plan The following description of the Plan provides only general information. The provisions of the Plan are governed in all respects by the detailed terms and conditions contained in the Plan itself. The Plan is a defined contribution plan established to encourage and facilitate systematic retirement savings and investment by eligible employees of Dover Corporation ("Dover"). Participating units of Dover may participate in (i) the salary reduction and matching contribution portions of the Plan, (ii) the profit-sharing contribution portion of the Plan, or (iii) both. All employees of such participating units who have reached age 21 and completed one year of service are eligible to participate in the Plan, except in the case of certain participating units whose employees are immediately eligible to join the plan after attaining age 21. Salary reduction contributions to the Plan are voluntary. A participant may elect to exclude from 1% to 18% in whole percentages of his or her compensation (the "Deferred Amount") from current taxable income by contributing it to the Plan. The amount contributed is subject to applicable Internal Revenue Code limits, and the percentage of compensation contributed by highly compensated employees may be further limited to enable the Plan to satisfy nondiscrimination requirements. In addition, the Internal Revenue Code limits to $160,000 (as adjusted for cost-of-living increases) the amount of compensation that may be taken into account under the Plan. Each participating Dover unit (Employers) made contributions to the Plan on behalf of the Participants employed by it equal to a percentage of the first 6% of earnings included in the Deferred Amount (the "Employer Matching Contribution"). At the discretion of an Employer's Board of Directors, an additional year-end Employer Matching Contribution may be made to the Plan on behalf of Participants employed on the last day of the year. Basic and additional matching contributions are subject to an aggregate limit on such contributions of 200% of the first 6% of compensation included in the Deferred Amount. All employer-matching contributions are initially invested in the Stock Fund. Participants are fully vested with respect to amounts attributable to their salary reduction amounts and matching contributions, except for participating units whose employees are immediately eligible, in which case employer matching contributions are subject to a one year of service vesting requirement. An Employer may elect to make Profit Sharing Contributions for a plan year with respect to its employees who have satisfied the age and service requirements described above. Such contributions will be allocated in proportion to the compensation of participants who are employed by that employer and are employees on the last day of the plan year. A participant's Profit-Sharing account vests at the rate of 20% per year of service (except in the case of certain Employers, whose employees' Profit-Sharing Contribution accounts are immediately vested). A participant's Profit-Sharing account becomes fully vested after five years, upon the attainment of age 65 while an employee, in the event of his or her death or permanent disability while an employee, or in the event of a plan termination. A participant's vested account balance in the Plan is distributable following the participant's retirement, death, or other termination of employment. On October 1, 1995 the Plan was amended to allow for installment distribution payments in the case of fully vested participants who have attained age 55. The Plan does not permit withdrawals during a Participant's active career, other than certain required distributions payable to participants who have attained age 70-1/2. A participant who has been active in the Plan for at least twelve months may request a loan from the Plan except that participants who have made rollovers into the Plan may request a loan without meeting the 12 month requirement. A maximum of three loans may be outstanding at any one time. The minimum a participant may borrow is $1,000, and the maximum amount is determined by the balance in

11 the participant's vested account as of the Valuation Date preceding the loan request in accordance with Department of Labor Regulations, as per the following schedule: Vested Account Balance Allowable Loan ------------------------------------------------------------------------------- less than or equal to $100,000 up to 50% of Vested Account Balance more than $100,000 $50,000 Loans are available for the acquisition of a home, medical expenses, education expenses, or other purposes approved by the Plan Administrator. These loans bear interest from 6% to 11%. Each Participant has the right to direct the entire amount of the Deferred Amount being allocated to his or her Savings Account during a Plan Year to be invested in one or more of the available Investment Funds in multiples of five percent. Each participant has the right at any time to move all or any portion of the amount in his or her account (including the amount attributable to Employer Matching Contributions) among the investment funds. Each participant has the right to rollover into the plan distributions from other qualified plans or conduit IRA's.
