These financial statements are the responsibility of the Program's management. My responsibility is to express an opinion on these financial statements based on my audit. I conducted my audit in accordance with generally accepted auditing standards. Those standards require that I plan and perform my audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. I believe that my audit provides a reasonable basis for my opinion. In my opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Tandy Employees Supplemental Stock Program as of December 31, 1999 and 1998, and results of its operations for the years ended December 31, 1999, 1998 and 1997 in conformity with generally accepted accounting principles. My audit was made 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 complying with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974 and is not a required part of the basic financial statements. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in my opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

The Program is subject to Title I of the Employee Retirement Income Security Act of 1974 (ERISA) relating to the protection of employee benefit rights, but is not subject to Title IV, relating to plan termination insurance coverage, and such insurance will not be extended to participants in the Program in the future. Contributions Prior to January 1, 1996, through authorized payroll deduction a participant could contribute 5% of his or her gross salary or wages to the Program after reaching a maximum salary deferral contribution limit under the Tandy Employees Deferred Salary and Investment Plan. Effective January 1, 1996 the contribution percentage could vary from 1 to 8% of his or her gross salary or wages after reaching a maximum salary deferral contribution limit under the Tandy Fund. The Company makes contributions to the Program equal to 80% of the participant's contribution. Cash dividends are added to the participant's account as Other contributions paid on the shares of common stock credited to a participant's account. These Other contributions are not subject to matching contributions by the Company.
