Report of Independent Auditors Benefit Committee Gray Communications Systems, Inc. We have audited the accompanying statements of net assets available for benefits of the Gray Communications Systems, Inc. Capital Accumulation Plan as of December 31, 1999 and 1998, and the related statement of changes in net assets available for benefits for the year ended December 31, 1999. 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 in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audits 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 at December 31, 1999 and 1998 and the changes in its net assets available for benefits for the year ended December 31, 1999, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedules of Assets Held for Investment Purposes at End of Year as of December 31, 1999 and Reportable Transactions for the year ended December 31, 1999, are presented for purposes of additional analysis and are not a required part of the 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 our audits of the financial statements and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP May 18, 2000 1

Gray Communications Systems, Inc. Capital Accumulation Plan Notes to Financial Statements December 31, 1999 1. Description of the Plan The following brief description of the Gray Communications Systems, Inc. Capital Accumulation Plan (the "Plan") is provided for general information purposes only. Participants should refer to the Plan Document for more complete information. The Plan was established effective October 1, 1994 for the benefit of eligible employees of Gray Communications Systems, Inc., and of its subsidiaries and affiliates that subsequently adopt the Plan. General The Plan is a voluntary defined contribution plan for salaried and non-salaried employees of Gray Communications Systems, Inc. and its subsidiaries (the "Sponsor") who have completed one eligibility year of service as defined in the Plan document. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). While the Sponsor has not expressed any intent to do so, the Benefit Committee retains the right to terminate the Plan at any time, subject to the provisions of ERISA. In the event a decision is made by the Benefit Committee to terminate the Plan, all participants shall receive full distribution of the balances in their accounts. Trust Agreement Assets of the Plan are held for safekeeping and investment by INVESCO Trust Company (the "Trustee") as part of a trust agreement between the Sponsor and the Trustee. Contributions Each active Plan participant may make contributions up to a maximum of 16% of his/her compensation on a before-tax basis and up to a maximum of 16% on an after-tax basis, as long as the sum of the before-tax and after-tax percentages does not exceed 16%. Participant contributions made on a before-tax basis under Section 401(k) of the Internal Revenue Code (the "Code") can not exceed the elective contribution limit of $10,000 during 1999. Contributions by highly compensated employees are subject to additional restrictions. Upon enrollment, a participant may direct employee contributions in 10% increments to any of the Plan's fund options. Contributions to the Gray Communications Systems, Inc. Common Stock Fund are temporarily invested in a Retirement Trust Liquid Asset Fund until used to purchase Gray Communications Systems, Inc. common stock. Participants may change their investment options quarterly. 4

The Sponsor shall contribute to the Plan a matching percentage, as determined by a declaration of its Board of Directors before the beginning of any Plan year, of the eligible contributions of plan participants not to exceed 6% of eligible compensation as defined in the Plan document. The matching percentage was 50% for the year ended December 31, 1999. The Sponsor's matching contributions can be made either in shares of Gray Communications Systems, Inc. Class B common stock or in cash. Any forfeitures of Sponsor contributions are used to reduce future Sponsor contributions. Forfeitures of nonvested amounts were approximately $80,700 for the year ended December 31, 1999. 5

Gray Communications Systems, Inc. Capital Accumulation Plan Notes to Financial Statements (continued) 1. Description of the Plan (continued) Vesting Participants are fully vested with regard to their contributions. Participants vest in the Sponsor's contributions after completing five years of service, as defined in the Plan document. Withdrawals A participant may withdraw all or part of his/her after-tax contributions for any reason, subject to the suspension of such participant's rights to make after tax contributions for six months. Hardship withdrawals may be available as defined by the Plan document. A participant making a hardship withdrawal is ineligible to contribute to the Plan for the next twelve months from the date of receipt of the withdrawal and is prohibited from making any elective or employee contributions to all other plans of the Sponsor, including, but not limited to, any stock option, stock purchase or similar plan maintained by the Sponsor. Distributions A participant, following termination of employment, can elect to have Plan benefits paid in a single lump-sum distribution, in installments or in a combination of the two methods. At December 31, 1999, none of the net assets available for benefits were allocated to the accounts of persons who had withdrawn from participation in the Plan, but had not been paid. Such amounts would be, if any, recorded as benefits payable for purposes of the Plan's Form 5500. Loans The Plan provides for participant loans at rates of interest established by the Sponsor's Benefit Committee. Such loans are limited as defined by the Plan document. 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared based on the accrual method of accounting with investments carried at fair values as described below. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Investment Valuation 6

The collective trust funds are valued at their redemption prices (fair values) as established by the Trustee. Generally, the fair values are based on the fair values of the underlying assets which are based on national stock exchange closing prices or other published sources. Investments traded on a national securities exchange are valued at the last reported sales price on the last business day of the Plan year. Securities traded in the over-the-counter market are valued at the last reported sales price on the last business day of the Plan year. The participant loans are valued at their outstanding balances, which approximate fair value. 7

Gray Communications Systems, Inc. Capital Accumulation Plan Notes to Financial Statements (continued) 2. Summary of Significant Accounting Policies (continued) Investment Valuation (continued) Purchases and sales of securities are reflected on the trade dates. Dividend income is recorded on the ex-dividend date. Income from other investments is recorded as earned. Administrative Expenses All administrative and investment expenses, except for fund management fees, are paid by the Sponsor. There were no administrative and investment expenses paid by the Sponsor for the year ended December 31, 1999. Parties-in-Interest Transactions Plan assets included in the Collective Trust Funds are managed by INVESCO Trust Company ("INVESCO"). As INVESCO is the trustee, as defined by the Plan, transactions involving these investments are party-in-interest transactions. In addition, transactions involving the Common Stock Fund, which invests in the common stock of the Sponsor, also qualify as party-in-interest transactions. Reclassifications Certain amounts in the December 31, 1998 financial statements have been reclassified to conform to the December 31, 1999 presentation. 3. Income Tax Status The Plan has received a determination letter from the Internal Revenue Service dated October 25, 1995, stating that the Plan qualifies under Section 401(a) and 401(k) of the Internal Revenue Code (the "Code") and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Sponsor believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. 4. Investments During 1999, the Plan's investments including investments purchased, sold as well as held during the year appreciated (depreciated) in fair value as determined by quoted market prices as follows: Net Realized and Unrealized Appreciation (Depreciation) in Fair Value of Investments ---------------------------------- Principal Protection Fund $ 19,277 Intermediate Return Fund 55,620 Growth and Income Fund 314,946 8
