Report of Independent Accountants To the Participants and Administrator of the Callaway Golf Company 401(k) Profit Sharing Plan In our opinion, the financial statements listed in the accompanying index present fairly, in all material respects, the net assets available for benefits of the Callaway Golf Company 401(k) Profit Sharing Plan (the "Plan") at December 31, 1999 and 1998 and the changes in net assets available for benefits for the years then ended, 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 audits. We conducted our audits 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 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 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. This supplemental schedule is the responsibility of the Plan's management. 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. /s/ PricewaterhouseCoopers LLP San Diego, California June 9, 2000 -4-

Callaway Golf Company 401(K) Profit Sharing Plan Notes to Financial Statements December 31, 1999 and 1998 - ------------------------------------------------------------------------------ 1. Description of Plan General Callaway Golf Company (the "Company") adopted on December 12, 1991, effective January 1, 1991, a voluntary deferred compensation and profit sharing plan, the Callaway Golf Company 401(k) Profit Sharing Plan, as amended, (the "Plan"), to enable eligible employees to make pre-tax savings deferrals and to share in the Company's earnings, thereby providing employees with an opportunity to accumulate funds for their retirement. Eligible employees who are employed for at least six months and accrue 500 hours of service, and are age eighteen or older, may participate in the Plan. The Plan is administered by the Company and Wells Fargo Bank serves as the trustee. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates. Plan Merger On December 31, 1998, the Odyssey Golf 401(k) Plan (the "Odyssey Plan") merged with and into the Plan. As a result, $778,000 in net assets were transferred to the Plan. Contributions Participants can elect to defer from 1% to 10% of their compensation, subject to the maximum permitted under Federal law. Participants also may contribute amounts representing distributions (or "rollovers") from other qualified plans. During 1999 and 1998, the Company made matching contributions each pay period equal to 100% of the deferral rate elected by participants for deferral rates up to 6% of annual compensation. The Company also may make discretionary profit sharing contributions. For the Plan year 1999, the profit sharing contribution authorized by the Company and accrued by the Plan was $3,605,000. The entire contribution was received by the Plan in February 2000. Plan participants do not accrue earnings on contributions until such contributions are received by the Plan. There were no discretionary profit sharing contributions for the Plan year 1998. Participant Accounts Each participant's account is credited with the participant's contributions and an allocation of: (a) the Company's matching and profit sharing contributions; (b) Plan earnings; and (c) forfeitures related to terminated participants' nonvested balances. Only participants who are actively employed on the last day of the Plan year or have completed more than 500 hours of service during the year will be allocated forfeitures and profit sharing contributions. Allocations of the Company's profit sharing contributions and Plan forfeitures are based on each participant's compensation in relation to total compensation of all Plan participants. Plan forfeitures totaled $273,000 and $223,000 for the years then ended December 31, 1999 and 1998, respectively. Vesting Participants are fully vested in their pre-tax contributions and vest in Company matching and profit sharing contributions at a rate of 25% per year, becoming fully vested after the completion of four years of employment. -7-

Callaway Golf Company 401(K) Profit Sharing Plan Notes to Financial Statements December 31, 1999 and 1998 - ------------------------------------------------------------------------------ During 1998, the Plan was amended to allow certain participants terminated by the Company to receive, upon termination, 100% accelerated vesting in the unvested portion of their matching employer contributions account. Distributions Distributions to participants are payable when a participant retires, or is terminated and requests distribution of the vested value of his or her account. If the vested value of the participant's account exceeds $5,000, the participant is allowed by law to leave benefits on deposit with the Plan. The amount left on deposit and the interest earned thereon are not forfeitable. Investment Options Upon enrollment in the Plan, a participant may direct contributions to any of the following investment options: . Wells Fargo Money Market Fund - Invests primarily in U.S. Government and corporate debt securities with an average maturity of 30 to 45 days. . Wells Fargo Short-term Intermediate U.S. Government Fund - Invests in short to intermediate term debt obligations of the U.S. Treasury, government agencies, corporations, and mortgage and asset-backed securities. The average maturity of the fund is not to exceed 10 years. This investment is no longer available to participants for future contributions. . Wells Fargo Equity Value Fund - Seeks to provide long-term capital appreciation by investing in common stocks which the fund manager believes are undervalued. . Wells Fargo S&P 500 Stock Fund - Seeks to provide total returns comparable to the returns of the S&P 500 Stock Index by investing in the same stocks and in substantially the same percentages as the S&P 500 Index. . Wells Fargo Managed Investment Fund - Seeks a high level of total return consistent with reasonable risk by shifting investments among common stocks, bond and money market instruments. This fund became available to participants as of October 1, 1999. . T.

Callaway Common Stock Fund - Invests in the common stock of the Company. Included in the Callaway Common Stock Fund are funds held in a money market account that will be used to purchase or redeem shares of the Company's common stock. Plan Administrative Expenses Plan administrative expenses are paid by the Company. 2. Summary of Significant Accounting Policies Basis of Accounting The financial statements are prepared on the accrual basis of accounting. Investment Valuation Investments are valued at quoted market prices. Participant loans are stated at amortized cost which approximates fair value. The Plan presents in the statement of changes in net assets available for 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. Contributions Participant contributions and Company matching contributions are recorded in the period during which the Company makes payroll deductions from the participants' earnings. Company profit sharing contributions are recorded by the Plan when and if approved by the Company's Board of Directors. Distributions to Participants Distributions to participants are recorded when paid. 3. Participant Loans Participants may borrow up to 50% of their vested account balance in loan amounts ranging from a minimum of $1,000 to a maximum of $50,000. Such loans must be repaid within 5 years or, if used to purchase a principal residence, 15 years. The loans are secured by the balances in the participants' accounts, and bear interest equal to the current prime rate at the inception of the loan. The prime rate was 8.50% at December 31, 1999 and 7.75% at December 31, 1998. 4. 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. If the Plan is terminated, participants will become fully vested in their accounts. However, the Plan assets will first be used to pay any expenses of the Plan. 5. Income Taxes The Internal Revenue Service has determined, and informed the Company by a letter dated May 23, 1995, that the Plan and related trust are designed in accordance with the applicable sections of the Internal Revenue Code. The Plan has been amended since such determination, however, the Plan's administrator believes that the Plan is designed and is currently being -9-
