Report of Independent Accountants To the Participants and Administrator of DENTSPLY International Inc. 401(k) Savings Plan In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the DENTSPLY International Inc. 401(k) Savings Plan (the "Plan") at December 31, 1999, and the changes in net assets available for benefits for the year ended December 31, 1999 in conformity with accounting principles generally accepted in the United States. 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 audit. We conducted our audit of these statements in accordance with auditing standards generally accepted in the United States, 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 audit provides a reasonable basis for the opinion expressed above. Our audit was conducted 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 the purpose 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 is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit 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.

Significant Accounting Policies Basis of Accounting The accompanying financial statements have been prepared on the accrual basis of accounting. Financial Statement Presentation The Plan adopted American Institute of Certified Public Accountants Statement of Position 99-3, Accounting for and Reporting of Certain Defined Contribution Benefit Plan Investments and Other Disclosure Matters ("SOP 99-3"). Certain reclassifications of the 1998 amounts have been made to conform to the 1999 presentation in accordance with SOP 99-3. 11

Investment Valuation and Income Recognition The Plan's investments are stated at fair value. Shares of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. Common stock is valued at its quoted market price. Participant loans are valued at cost which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Payment of Benefits Benefits are recorded when paid. Plan Expenses Expenses incurred in connection with the administration of the Plan are paid by the Company. Reclassifications Certain amounts in the prior year financial statements have been reclassified to conform with the presentation of the current year financial statements. Use of Estimates 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 additions and deductions during the reporting period. Actual results could differ from those estimates. 3. Investments During 1999 and 1998, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated (depreciated) in value as follows: 1999 1998 Registered investment companies $5,267,120 $3,910,893 Common stock (140,032) (203,515) $5,127,088 $3,707,378 4. Related Party Transactions During 1999 and 1998, certain Plan investments were shares of a registered investment company managed by Schwab. Schwab is the trustee as defined by the Plan. The transactions in this fund are party-in-interest transactions exempt from prohibited transaction rules. 12

5. 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. 6. Plan Merger As a result of a business acquisition made by the Company during 1998, the GAC International, Inc. 401(k) Plan, with net assets of $2,281,052 was merged with and into the Plan in 1998. 7. Tax Status The Internal Revenue Service has determined and informed the Company by a letter dated March 25, 1994, that the Plan and related trust are 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 believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 13
