(with Independent Accountants’ Report thereon)

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees
United Community Banks, Inc. Profit Sharing Plan
Blairsville, Georgia

We have audited the accompanying statements of net assets available for plan benefits of United Community Banks, Inc. Profit Sharing Plan as of December 31, 2003 and 2002, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2003. 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 of the Public Company Accounting Oversight Board (United States). Those standards 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. 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 plan benefits of United Community Banks, Inc. Profit Sharing Plan as of December 31, 2003 and 2002 and the changes in its net assets available for plan benefits for the year ended December 31, 2003, in conformity with the United States generally accepted accounting principles.

Our audit of the Plan’s financial statements as of and for the year ended December 31, 2003, was performed 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 and has been subjected to the auditing procedures applied in our audit of the basic financial statements for the year ended December 31, 2003, and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.
