QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: What am I being asked to approve?

A: You are being asked to approve the Agreement and Plan of Reorganization by and between Gwinnett and United, pursuant to which Gwinnett will be merged with and into United. Approval of the merger requires the affirmative vote of a majority of the outstanding shares of Gwinnett common stock. The Gwinnett board of directors has unanimously approved and adopted the Agreement and Plan of Reorganization and recommends voting FOR approval of this merger agreement.

Q: When is the merger expected to be completed?

A: We plan to complete the merger during the second quarter of 2007.

Q: What will I receive in the merger?

A: Unless adjusted pursuant to the terms of the merger agreement, you will receive either (i) 2.2545 shares of United common stock, or (ii) $72.8865 in cash, without interest, for each share of Gwinnett common stock; provided, that an aggregate of no more than 306,137 shares of Gwinnett common stock may be exchanged for cash and an aggregate of no more than 2,524,764 shares of Gwinnett common stock may be exchanged for United common stock. United will not issue fractional shares in the merger. Instead, you will receive a cash payment, without interest, for the value of any fraction of a share of United common stock that you would otherwise be entitled to receive based on $32.33 per share.

For example:

Assuming the stock exchange ratio remains 2.2545 and stock elections are not subject to proration, if you own 100 shares of Gwinnett common stock and elect to receive all stock in the merger, you will be entitled to 225 shares of United common stock (100 x 2.2545, rounded down to the nearest whole share). In addition, you will be entitled to receive $14.55 in cash for your .45 fractional share of United (.45 x $32.33).

To review what you will receive in the merger in greater detail, see “Details of the Proposed Merger-The Merger Consideration” beginning on page 17.

Q: What should I do now?

A: Indicate on the enclosed proxy card how you want to vote with respect to the proposed merger, and sign and mail the proxy card in the enclosed envelope as soon as possible so that your shares will be represented at the meeting. If you sign and send in a proxy card but do not indicate how you want to vote, your proxy will be voted in favor of the proposal to approve the merger. A special shareholders meeting will take place on June 1, 2007, at 8:00 a.m. at the main office of First Bank of the South, 2230 Riverside Parkway, Lawrenceville, Georgia 30043, to vote on the merger proposal.

You may withdraw your proxy up to and including the day of the special meeting by notifying Gwinnett prior to the meeting, in writing, or by submitting an executed, later-dated proxy to: Andrew R. Pourchier, Executive Vice President, Chief Financial Officer and Secretary, Gwinnett Commercial Group, Inc., 2230 Riverside Parkway, Lawrenceville, Georgia 30043.

-1-

Q: How can I elect stock, cash or both?

A: You may indicate a preference to receive United common stock, cash or a combination of both in the merger by completing the enclosed election form. However, an aggregate of no more than 306,137 shares of Gwinnett common stock may be exchanged for cash and an aggregate of no more than 2,524,764 shares of Gwinnett common stock may be exchanged for United common stock. Accordingly, if the aggregate cash elections are greater than the maximum, each cash election will be reduced pro rata based on the amount that the aggregate cash elections exceed the maximum. Alternatively, if the aggregate stock elections are greater than the maximum, each stock election will be reduced pro rata based on the amount that the aggregate stock elections exceed the maximum. If you do not make an election by or at the special shareholders meeting to be held on June 1, 2007, you will be treated as though you elected to receive all cash unless cash has been fully subscribed by the electing Gwinnett shareholders, in which event you will be treated as if you elected all stock. Gwinnett’s board of directors makes no recommendation as to whether you should choose United common stock or cash or a combination of both for your shares of Gwinnett Commercial Group, Inc. common stock. You should consult with your own financial advisor on that decision.

Q: What information should I consider?

A: We encourage you to read this entire document carefully. You should also review the factors considered by each company’s board of directors discussed in “Details of the Proposed Merger-Background of and Reasons for the Merger” beginning on page 14.

Q: What will I receive as consideration for the Gwinnett stock options and/or stock appreciation rights I hold?

A: Each Gwinnett option holder has agreed not to exercise his or her options prior to the closing of the merger. In exchange, United has agreed to pay the holder of each option $72.8865 in cash less the exercise price of each option. United has also agreed to pay the holder of each Gwinnett stock appreciation right, which we refer to as a “SAR”, $72.8865 in cash less the exercise price of each SAR.

Q: What are the tax consequences of the merger to me?

A: We expect that the exchange of shares of Gwinnett common stock for United common stock by Gwinnett shareholders generally will be tax-free to you for federal income tax purposes. However, you will have to pay taxes at either capital gains or ordinary income rates, depending upon individual circumstances, on cash received (i) in exchange for your shares of Gwinnett common stock; (ii) in lieu of fractional shares of United Stock; (iii) if you are a Gwinnett option and/or SARs holder, in exchange for your options and/or SARs; and (iv) upon your exercise of dissenters’ rights. To review the tax consequences to Gwinnett shareholders and option and SARs holders in greater detail, see “Details of the Proposed Merger-Material Federal Income Tax Consequences of the Merger and Opinion of Tax Counsel” beginning on page 30.

Your tax consequences will depend on your personal situation. You should consult your tax adviser for a full understanding of the tax consequences of the merger to you.

-2-

Q: Should I send in my stock certificates now?

A: No. After the merger is completed, you will receive written instructions from United for exchanging your Gwinnett common stock certificates for United common stock and/or cash.

Q: Who should I call with questions?

A: You should call Andrew R. Pourchier, Executive Vice President, Chief Financial Officer and Secretary of Gwinnett at (770) 237-0007.

·	The Terms of the Merger (see page 19)

If Gwinnett shareholders approve the merger and subject to required regulatory approvals, Gwinnett will be merged with and into United. Unless adjusted pursuant to the terms of the merger agreement, Gwinnett shareholders may elect to receive shares of United common stock or cash in exchange for each of their shares of Gwinnett common stock in the merger on the following basis:

2.2545 shares of United common stock; or

$72.8865 in cash, without interest;

provided, that an aggregate of no more than 306,137 shares of Gwinnett common stock may be exchanged for cash and an aggregate of no more than 2,524,764 shares of Gwinnett common stock may be exchanged for United common stock. You may elect any combination of stock or cash for all of your Gwinnett shares. If the aggregate cash elections are greater than the maximum, all such cash elections will be subject to proration, and, if the aggregate stock elections are greater than the maximum, all such stock elections will be subject to proration.

You will also receive a cash payment, without interest, for the value of any fraction of a share of United common stock that you would otherwise be entitled to receive based on $32.33 per share.

Following the merger, Gwinnett’s subsidiary, First Bank of the South, will be merged with and into United Community Bank, a wholly-owned Georgia bank subsidiary of United, and United Community Bank will be the surviving bank.

·	The Reasons Management of Both Companies Support the Merger (see page 14)

The boards of directors of Gwinnett and United support the merger and believe that it is in the best interests of both companies and their respective shareholders. The board of directors of Gwinnett believes that the merger will allow Gwinnett to better serve its customers and markets and that the merger will permit Gwinnett shareholders to have an equity interest in a resulting financial institution with greater financial resources, significant economies of scale and a larger shareholder base, which will increase the liquidity of the Gwinnett shareholders’ equity investments. The board of directors of United believes that Gwinnett provides United with an expansion opportunity in an attractive market area. Both boards of directors believe that the terms of the merger are fair and equitable and that following the merger the combined bank will maintain the competitive advantage of a community banking business model.

·	Shareholders’ Meeting

The special meeting of shareholders of Gwinnett will be held on June 1, 2007 at 8:00 a.m., at the main office of First Bank of the South, 2230 Riverside Parkway, Lawrenceville, Georgia 30043, for the purpose of voting on approval of the merger.

-5-

·	Record Date

You are entitled to vote at the shareholders’ meeting if you owned shares of Gwinnett common stock on May 1, 2007.

·	Vote Required (see page 22)

Approval by holders of a majority of the Gwinnett common stock outstanding on May 1, 2007, is required to approve the merger. As of such date, 2,830,901 shares of Gwinnett common stock were issued and outstanding, each of which is entitled to one vote per share. All of the directors, executive officers and 5% shareholders of Gwinnett have agreed to vote their shares in favor of the merger. Gwinnett’s directors, executive officers and 5% shareholders own 1,228,697 shares, or 43.40%, of Gwinnett common stock (excluding options).

·	Conditions, Termination, and Effective Date (see page 20)

The merger will not occur unless certain conditions are met, and United or Gwinnett can terminate the merger agreement if specified events occur or fail to occur. The merger must also be approved by the Gwinnett shareholders. Following the merger, Gwinnett’s subsidiary, First Bank of the South, will be merged into United’s Georgia bank subsidiary, United Community Bank.

The closing of the merger will occur after the merger is approved by Gwinnett shareholders and the foregoing regulators and after the certificate of merger is filed as required under Georgia law.

·	Rights of Dissenting Shareholders (see page 28)

You are entitled to dissent from the merger and to receive a cash payment for your Gwinnett common stock if you follow certain statutory provisions regarding the rights of dissenting shareholders under Article 13 of the Georgia Business Corporation Code.

·	Federal Income Tax Consequences (see page 30)

Gwinnett has received an opinion from Kilpatrick Stockton LLP stating that, assuming the merger is completed as currently anticipated, Gwinnett will not recognize any gain or loss for federal income tax purposes, and shareholders of Gwinnett to the extent they receive solely United stock will not recognize any gain or loss for federal income tax purposes. All cash you receive as a result of the merger (i) pursuant to a cash election, (ii) in lieu of fractional shares, (iii) if you are a Gwinnett option and/or SARs holder, in exchange for your options and/or SARs, and (iv) as payment for exercising your right to dissent, will be fully or partially subject to income tax under the Internal Revenue Code as either ordinary income or a capital gain or loss, depending upon your particular circumstances. Neither United nor Gwinnett has requested a ruling to this effect from the Internal Revenue Service.

-6-

·	Accounting Treatment (see page 27)

The merger will be accounted for as a purchase for financial reporting and accounting purposes.

·	Opinion of Gwinnett’s Financial Advisor (see page 31)

Burke Capital Group, L.L.C. has rendered an opinion to Gwinnett that based on and subject to the procedures, matters, and limitations described in its opinion and other matters it considered relevant, as of the date of its opinion, the merger consideration is fair from a financial point of view to the shareholders of Gwinnett. A summary of Burke’s opinion begins on page 29 and the full opinion is attached as Appendix C to these materials.

United’s common stock trades on the Nasdaq Stock Market under the ticker symbol “UCBI”. The following table sets forth, for the periods indicated, the high, low and closing sales prices per share of United’s common stock as quoted on Nasdaq. Amounts have been restated to reflect the pro forma effect of United’s three-for-two split effective April 28, 2004:

	High		Low		Close

Second Quarter		26.44		21.70		26.02
First Quarter		27.92		23.02		23.73

2004
Fourth Quarter		29.60		23.17		26.93

The closing sales price of United common stock as of February 5, 2007, the date the merger agreement was executed, was $33.06. The closing sales price of United common stock as of May 1, 2007, the most recent date feasible for inclusion in these materials, was $29.89.

There has been no public trading market for Gwinnett common stock. We believe the last sale of Gwinnett common stock among shareholders in a private transaction was on November 13, 2006 at a price of $60.00 per share, based on unofficial information that Gwinnett management believes is reliable.

-7-

Assuming there is no adjustment in the merger consideration, if the merger had been completed on February 5, 2007, the implied value of one share of Gwinnett common stock, exchanged for shares of United common stock in the event of a stock election, would have been $74.53 based on United’s closing sales price on that date, and, on May 1, 2007, the implied value of one share of Gwinnett common stock, exchanged for shares of United common stock, would have been $73.97. The value of one share of Gwinnett common stock exchanged for cash is fixed at $67.38.

There were 287 shareholders of record of Gwinnett common stock as of May 1, 2007.

·	Dividends (see page 27)

United declared cash dividends of $.18 per share, in the aggregate, in the first and second quarters of 2007, $.32 per share in 2006, $.28 per share in 2005 and $.24 per share in 2004. United intends to continue paying cash dividends, but the amount and frequency of cash dividends, if any, will be determined by United’s board of directors after consideration of certain non-financial and financial factors including earnings, capital requirements, and the financial condition of United, and will depend on cash dividends paid to it by its subsidiary banks. The ability of United’s subsidiary banks to pay dividends to it is restricted by certain regulatory requirements.

Pursuant to the terms of the merger agreement, Gwinnett declared a cash dividend of $3.80 per share (which includes a regular annual cash dividend of $1.55 per share) to record holders as of February 5, 2007 payable on March 12, 2007. Gwinnett declared cash dividends of $1.45 per share in 2006, $1.35 per share in 2005 and $1.25 per share in 2004.

·	Differences in Legal Rights Between Shareholders of Gwinnett and United (see page 26)

Following the merger you will no longer be a Gwinnett shareholder and, if you receive shares of United common stock following the merger, your rights as a shareholder will no longer be governed by Gwinnett’s articles of incorporation and bylaws. You will be a United shareholder, and your rights as a United shareholder will be governed by United’s articles of incorporation and bylaws. Your former rights as a Gwinnett shareholder and your new rights as a United shareholder are different in certain ways, including the following:

Gwinnett’s board of directors consists of 15 members, while United’s consists of 11 members.

The bylaws of Gwinnett set forth different requirements for removal of directors than do the articles of incorporation and bylaws of United.

United has different special procedures in its articles of incorporation requiring supermajority approval and disinterested shareholder approval of some business transactions.

The articles of incorporation of United require a supermajority shareholder vote to amend most provisions of its articles of incorporation and bylaws. Gwinnett’s articles of incorporation and bylaws do not.

United is subject to filing requirements under the Securities Exchange Act. Gwinnett is not subject to such requirements.

-8-

·	Interests of Directors and Officers of Gwinnett in the Merger (see page 24)

Some of the directors and officers of Gwinnett have interests in the merger in addition to their interests as shareholders generally, including the following:

Glenn S. White, President and Chief Executive Officer of Gwinnett will terminate his employment agreement with Gwinnett and has entered into a settlement agreement with United for a payment equal to $939,550, as required by his existing employment agreement upon his termination following a change in control of Gwinnett and reduced to prevent such payment from being an amount that would be considered an “excess parachute payment” under the Internal Revenue Code. Mr. White has entered into a new employment agreement with United for a rolling three-year term, and will be granted 10,000 shares of restricted stock, which will vest on the fifth anniversary of the closing of the merger, and options to purchase 25,000 shares. The options vest as follows: 50% on the third anniversary, 25% on the fourth anniversary and 25% on the fifth anniversary of the closing of the merger.

Steven W. Williams, President of First Bank of the South and Executive Vice-President of Gwinnett will terminate his employment agreement with Gwinnett and has entered into a settlement agreement with United for a payment equal to $443,467, as required by his existing employment agreement upon his termination following a change in control of Gwinnett. Mr. Williams has entered into a new employment agreement with United for a rolling two-year term, and will be granted 7,000 shares of restricted stock, which will vest on the fifth anniversary of the closing of the merger, and options to purchase 17,500 shares. The options vest as follows: 50% on the third anniversary, 25% on the fourth anniversary and 25% on the fifth anniversary of the closing of the merger.

Andrew R. Pourchier, Executive Vice President, Chief Financial Officer and Secretary of Gwinnett, has entered into a one year consulting agreement with United and will terminate his employment agreement with Gwinnett for a payment equal to $442,467, as required by his existing employment agreement upon his termination following a change in control of Gwinnett.

At the closing of the merger, various other Gwinnett officers will terminate their respective employment agreement with Gwinnett and have entered into a settlement agreement with United for a payment equal to the amount required by their existing employment agreements upon their respective termination following a change in control of Gwinnett. Each of these officers have entered into an employment agreement with United.

In exchange for a payment by United, various Gwinnett lending officers have entered into non-competition agreements with United that will prohibit the officers from competing with United after the closing of the merger if their employment is terminated.

United will generally indemnify and provide liability insurance to the present directors and officers of Gwinnett Commercial and First Bank of the South for a period of three years following the closing of the merger for actions taken by such directors and officers in such capacity.

GAAP Reconciliation and Explanation

United’s net operating income is determined by methods other than in accordance with GAAP and excludes merger-related charges. United excludes these charges because management believes that non-GAAP operating results provide a helpful measure for assessing United’s financial performance since the excluded charges are non-recurring and operating income more closely reflects what United earned during the applicable periods disregarding the non-operating impact of acquisitions. United’s net operating income should not be viewed as a substitute for net income determined in accordance with GAAP and is not necessarily comparable to non-GAAP performance measures that may be presented by other companies. The following is a reconciliation of United’s net operating income to GAAP net income:

RISK FACTORS

In addition to the other information, including risk factors, incorporated by reference herein from United’s Annual Report on Form 10-K for the year ended December 31, 2006 , you should carefully read and consider the following factors in evaluating the merger and in deciding whether to elect to receive cash, shares of United common stock or some combination thereof in the merger.

Because the market price of United common stock will fluctuate, Gwinnett shareholders electing to receive stock cannot be sure of the value of the merger consideration they will receive.

Upon completion of the merger, each share of Gwinnett common stock will be converted into the merger consideration consisting of shares of United common stock or cash. The market value of the merger consideration received by Gwinnett shareholders who receive all or part of the merger consideration in the form of United shares will vary with the price of United’s common stock. United’s stock price changes daily as a result of a variety of factors other than the business and relative prospects of United, including general market and economic conditions, industry trends, and the regulatory environment. These factors are beyond United’s control.

Gwinnett shareholders may receive a form of consideration different from what they elect.

For example, if you elect to receive cash for 1,000 Gwinnett shares and the aggregate cash elections exceed by 10% the 306,137 Gwinnett share maximum, the shares for which you will be paid cash will be reduced to the number determined by dividing your cash election by the aggregate cash elections and multiplying that quotient by the 306,137 cash election maximum. This proration will result in you receiving cash for 909 of your Gwinnett shares and being treated as if you had elected to receive stock for your remaining 91 shares.

At the time you vote with respect to the merger agreement, you will not know how much cash or the number of United shares you will receive as a result of the merger.

Gwinnett’s officers and directors have interests in the merger in addition to or different from your interests as a Gwinnett shareholder.

Some of Gwinnett’s executive officers participated in negotiations of the merger agreement with United, and the board of directors approved the merger agreement and is recommending that Gwinnett shareholders vote for the merger agreement. In considering these facts and the other information contained in these materials, you should be aware that certain of Gwinnett’s executive officers and directors have economic interests in the merger in addition to the interests that they share with you as a Gwinnett shareholder. These interests include the payment of certain benefits in consideration of the termination of existing employment agreements, the employment of several of Gwinnett’s current executive officers by United following completion of the merger and the appointment of John D. Stephens, the chairman of the board of directors of Gwinnett, to the board of directors of United. See “Details of the Proposed Merger — Interest of the Directors and Officers of Gwinnett in the Merger” on page 24.

-12-

United may be unable to successfully integrate Gwinnett’s operations and retain its key employees.

The merger involves the integration of two companies that previously operated independently. The difficulties of combining the companies’ operations include integrating personnel, departments, systems, operating procedures and information technologies and retaining key employees. Failures in integrating operations or the loss of key personnel could have a material adverse effect on the business and results of operations of the combined company.

If the merger is not completed, United and Gwinnett common stock could be materially adversely affected.

The merger is subject to customary conditions to closing, including the approval of the Gwinnett shareholders. In addition, United and Gwinnett may terminate the merger agreement under certain circumstances. If United and Gwinnett do not complete the merger, the market price of United common stock or Gwinnet common stock may fluctuate to the extent that the current market prices of those shares reflect a market assumption that the merger will be completed. Further, whether or not the merger is completed, United and Gwinnett will also be obligated to pay certain investment banking, legal and accounting fees and related expenses in connection with the merger, which could negatively impact results of operations when incurred. In addition, neither company would realize any of the expected benefits of having completed the merger. If the merger is not completed, United and Gwinnett cannot assure their respective shareholders that additional risks will not materialize or not materially adversely affect the business, results of operations and stock prices of United and Gwinnett.

The termination fee contained in the merger agreement may discourage other companies from trying to acquire Gwinnett.

Gwinnett has agreed to pay a termination fee of $7.5 million to United if, under certain circumstances, the merger agreement is terminated and, at the time of termination, a competing offer is outstanding or such offer has been accepted by Gwinnett. This fee could discourage other companies from trying to acquire Gwinnett.

DETAILS OF THE PROPOSED MERGER

Background of and Reasons for the Merger

In exercising their fiduciary responsibilities to shareholders, Gwinnett’s management and board of directors regularly assess the local banking industry, including the regulatory and competitive environment for banking services. The board of directors has, over time, considered the possibility of a number of strategic options in evaluating ways to maximize shareholder value. As a result of Gwinnett’s historical growth and performance, management and the board of directors began to consider the company’s strategic alternatives in the summer of 2006, including, but not limited to, capital planning, a de novo branching strategy, acquisitions of other community banks, and pursuing a sale or merger transaction.

In June 2006, Gwinnett elected to engage an investment banking firm to advise it on general investment banking matters including the operating and merger and acquisition environment in Atlanta and, more specifically, the potential acquisition of other community banks or the sale of the company. Gwinnett engaged Burke Capital Group, L.L.C. as its financial advisor based on its extensive experience advising financial institutions and other qualifications. Burke has detailed knowledge of Gwinnett, is very familiar with the Southeastern U.S. banking market and, to a greater extent, the Atlanta banking market, and had significant knowledge of potential partners for a merger or sale of Gwinnett.

Burke held discussions with senior management of Gwinnett to compile a list of the most likely strategic partners in the event that Gwinnett decided to pursue a sale transaction. In the following weeks, Burke obtained and reviewed several detailed reports provided by Gwinnett including: company history, markets, management, past and current financial performance, projected financial performance, business plan, asset quality, branch locations and a variety of other financial and non-financial information. Burke utilized this data to compile a package of confidential financial and business information regarding Gwinnett to be used by Burke as a marketing tool for initial discussions with selected strategic partners.

From June through August 2006, Burke contacted ten bank holding companies with known interest in the Atlanta marketplace. Burke entered into confidentiality agreements on behalf of Gwinnett with seven of these companies and provided each with a package of confidential financial and business information regarding Gwinnett. From August through December 2006, several of these companies, including United, held meetings with senior management of Gwinnett to discuss Gwinnett’s strategic direction and a potential acquisition of the company.

During December 2006, Gwinnett held several meetings with the management of United to assess combining the respective organizations. In late December 2006, Gwinnett, United and Burke met to discuss the preliminary terms of a potential acquisition by United. United expressed an oral preliminary indication of interest utilizing 85% stock and 15% cash consideration for a purchase price of approximately $205 million.

On January 4, 2006, Burke met with the Gwinnett board of directors to discuss the initial oral indication of interest received from United. Burke and Gwinnett considered the United offer as well as the timing and expectation of offers from the other interested parties. Gwinnett discussed its obligations to give due consideration to all relevant factors, including the short-term and long-term interests of Gwinnett’s employees, customers, shareholders and other constituents. The Gwinnett board of directors authorized the executive officers of Gwinnett and Burke to continue to negotiate the price and other terms of a transaction with United.

-14-

Throughout January 2007, the parties continued to negotiate the merger consideration, the treatment of outstanding options to purchase Gwinnett common stock in the merger and the ability of Gwinnett to pay a pre-closing dividend to its shareholders. As the parties negotiated that purchase price, they also discussed whether (1) the purchase price would be a fixed amount and the exchange ratio for United stock would fluctuate or the exchange ratio for United stock would be fixed and the purchase price would fluctuate, and (2) the purchase price would be subject to adjustment in the event of a substantial increase or decrease in the market price of United’s stock.

After extensive negotiations, the parties agreed on a purchase price of $216.5 million based on the recent average trading price of United common stock of $32.33, which equated to 5.7 million shares of United common stock and $32.5 million in cash to stockholders and holders of Gwinnett options and stock appreciation rights. In addition to the merger consideration, the parties agreed that Gwinnett shareholders would receive their regularly scheduled annual cash dividend of $1.55 from Gwinnett payable in March 2007 and a special cash dividend not to exceed $2.25 per share (which is in part attributable to 2007 earnings), both payable prior to the closing of the transaction, and that United would purchase outstanding Gwinnett stock options and stock appreciation rights for cash. On January 10, 2007, United provided a term sheet to Gwinnett, which summarized the material terms of the proposed transaction.

The Gwinnett board of directors met on January 16, 2007 and approved the term sheet and authorized the executive officers to proceed with the negotiation and preparation of a definitive merger agreement. The board also reviewed a memorandum provided by Powell Goldstein LLP, legal counsel to Gwinnett, regarding the legal standards applicable to its decisions and actions with respect to the proposed transactions. The parties then scheduled their respective due diligence investigations of the other party, and counsel for each party began the preparation of a definitive merger agreement.

On February 5, 2007, the Gwinnett board of directors met to evaluate and discuss the proposed definitive merger agreement between Gwinnett and United. Burke rendered to the Gwinnett board of directors its oral opinion (subsequently confirmed in writing) that, as of the date of its opinion and based upon and subject to the considerations described in its opinion and other matters that Burke considered relevant, the proposed merger consideration was fair, from a financial point of view, to Gwinnett’s common stockholders. Powell Goldstein briefly reviewed the memorandum that was previously provided to the Gwinnett board of directors regarding the legal standards applicable to its decisions and actions with respect to the proposed transactions. Powell Goldstein also reviewed the legal terms of the proposed merger and the related agreements.

On February 5, 2007, following a thorough review and discussion, the Gwinnett board of directors voted to approve the Agreement and Plan of Reorganization providing for the merger of Gwinnett with United. Gwinnett and United finalized, executed, and delivered the definitive agreements for the transaction on that date. The transaction was announced publicly prior to the opening of the trading markets on February 6, 2007.

Without assigning any relative or specific weights, the board of directors of Gwinnett considered the following material factors in approving the merger:

Positive Factors:

The value and form of the consideration to be received by Gwinnett shareholders relative to the actual, tangible and leveraged book value, core deposits and aggregate and per share earnings of Gwinnett;

-15-

Information concerning the financial condition, results of operations and business prospects of Gwinnett and of United;

The financial terms of recent business combinations in the financial services industry and a comparison of the multiples of selected combinations with the terms of the proposed transaction with United;

A report and opinion presented by Burke as to the fairness, from a financial point of view, of the consideration to be paid to the company’s shareholders in the merger;

Gwinnett shareholders’ ability to elect to receive United common stock or cash in exchange for their Gwinnett common stock;

The special dividend of $2.25 per share to be paid to Gwinnett’s shareholders in addition to their regular annual dividend of $1.55 per share;

The liquidity of the consideration to be received by Gwinnett’s shareholders in the merger in light of United’s status as a Nasdaq-listed company;

The cultural fit between the Gwinnett and United community banking business models;

United’s positive record in retaining customers and employees following business combination transactions;

The alternatives to the merger, including remaining an independent institution;

The competitive and regulatory environment for financial institutions generally; and

The fact that the merger is structured as a tax-free reorganization and the exchange of Gwinnett common stock for United common stock will occur on a tax-free basis.

Negative Factors:

· Gwinnett shareholders will receive a dividend downgrade of approximately 46% based on Gwinnett’s and United’s respective dividend rates as of December 31, 2006;

· Collectively, the Gwinnett shareholders will not hold a controlling interest in the resulting company; and

· The risk that the combined company may not realize the expected benefits from the merger if United and Gwinnett are not successful in integrating the two companies following the merger.

The Gwinnett board of directors believes that analyses performed by Burke in connection with rendering its opinion to the board, taken as a whole, support the boards’ recommendation to the Gwinnett shareholders to approve the proposed merger. The Gwinnett board of directors considered in its review of the analyses performed by Burke all of the individual factors that did not support a recommendation to the Gwinnett shareholders to approve the proposed merger. These factors included:

the price to the last twelve months earnings multiple and the associated implied value of the merger consideration was less than the median price to the last twelve months earnings multiples and associated implied values of the consideration received in 10 comparable southeast transactions and 25 comparable U.S. transactions;

-16-

the price to actual book value multiple and the associated implied value of the merger consideration was less than the median price to actual book value multiples and associated implied values of the consideration received in 10 comparable southeast transactions and 25 comparable U.S. transactions;

the price to tangible book value multiple and the associated implied value of the merger consideration was less than the median price to tangible book value multiples and associated implied values of the consideration received in 10 comparable southeast transactions and 25 comparable U.S. transactions;

the contribution analysis indicated that the pro forma ownership of United common stock issuable to Gwinnett shareholders assuming a hypothetical 100% stock transaction in the merger was slightly less than the earnings contributed to United by Gwinnett; and

the selected peer group analysis of United indicated that the liquidity for United’s common stock is low compared to the selected peer group.

After careful consideration of these factors and the potential short- and long-term benefits to Gwinnett shareholders, the Gwinnett board of directors determined that the overall potential benefits of the merger outweighed these negative factors.

The board of directors of Gwinnett believes the merger is in the best interest of its shareholders and will allow Gwinnett to better serve its customers and markets. The merger will permit Gwinnett shareholders to have an equity interest in a resulting financial institution with greater financial resources, significant economies of scale and a larger shareholder base, which will increase the liquidity of the Gwinnett shareholders’ equity investments. The board of directors of Gwinnett also believes that the terms of the merger, including the basis of exchange of United common stock for Gwinnett common stock, which was determined through arms-length negotiations between United and Gwinnett, are fair and equitable and take into account the relative earning power of United and Gwinnett, historic and anticipated operations, the economies of scale to be achieved through the merger, the trading prices of the shares of the respective companies, and other pertinent factors.

The board of directors of Gwinnett believes that in the current regulatory and competitive environment, a partnership with a larger organization with a more diverse franchise, greater economies of scale, larger capital base, more diverse product line, and a superior ability to attract talented employees provides a distinct competitive advantage, and that following the merger the combined bank will maintain the competitive advantage of a community banking business model.

The Merger Consideration

Unless adjusted pursuant to the terms of the merger agreement, Gwinnett shareholders may elect to receive shares of United common stock or cash in exchange for each of their shares of Gwinnett common stock in the merger on the following basis:

2.2545 shares of United common stock; or

$72.8865 in cash, without interest;

provided, that an aggregate of no more than 306,137 shares of Gwinnett common stock may be exchanged for cash and an aggregate of no more than 2,524,764 shares of Gwinnett common stock may be exchanged for United common stock. Although each Gwinnett shareholder may elect to receive cash or stock, if the aggregate cash elections are greater than the maximum, each cash election will be reduced pro rata based on the amount that the aggregate cash elections exceed the maximum. Alternatively, if the aggregate stock elections are greater than the maximum, each stock election will be reduced pro rata based on the amount that the aggregate stock elections exceed the maximum.

-17-

At the time you vote with respect to the merger agreement, you will not know how much cash or the number of United shares you will receive as a result of the merger.

United will not issue fractional shares in the merger. Instead, you will receive a cash payment, without interest, for the value of any fraction of a share of United common stock that you would otherwise be entitled to receive based on $32.33 per share.

Merger Consideration Adjustment and Termination Rights

Because a portion of the merger consideration includes United common stock payable at a fixed exchange ratio for Gwinnett common stock and the market value of the United common stock changes daily, the total value of the merger consideration will fluctuate. Neither United nor Gwinnett can give you any assurance as to the price of United common stock or the value of the merger consideration when the merger becomes effective or when United’s shares are delivered to you. As an illustration, assuming the merger had been completed on February 5, 2007, the date the merger agreement was executed, the aggregate merger consideration payable pursuant to stock and cash elections (which does not include $10,165,563 payable to holders of Gwinnett options and SARs) would have been $210,493,434. However, assuming the merger had been completed on May 1, 2007, the most recent date available before these materials were mailed, the aggregate merger consideration payable pursuant to stock and cash elections would have been $192,449,585.

Under the merger agreement, the merger consideration may be adjusted if the average closing price of United common stock for the 30 day period preceding the six trading days prior to the Closing Date is greater than $33.56 or less than $29.09 per share and the percentage change in the United stock price is greater than the concurrent percentage change in the average price per share of the peer group of comparable companies specified in the merger agreement. In such case, the stock or cash portion of the merger consideration may be adjusted by the amount which would cause the value of the portion of the merger consideration payable in United stock to be increased or decreased by the lesser of (i) the difference between the percentage change in the United stock price and the percentage change in the peer group stock price, or (ii) the difference between the percentage change in the United stock price and a 10% change.

For example, assume that United’s average closing price decreased 15% from $32.33 to $27.48 and that the concurrent average price per share of the peer group decreased 12%. In that case, the aggregate merger consideration would have decreased from the $210,493,434 value on February 5, 2007 to $178,731,625. Gwinnett would then have the right to terminate the merger agreement because the percentage decrease in the United stock price is greater than 10% and the percentage change in the United stock price is greater than the percentage change in the average price per share of the peer group. United can prevent the merger agreement from terminating by electing to increase the merger consideration by an amount equal to 3% of the value of the stock consideration. In this example, 3% is the difference between the percentage change in the United stock price and the percentage change in the peer group stock price, which is less than the difference between the percentage change in the United stock price and 10%. This increase would cause the total merger consideration to increase to $184,252,375. If United elected not to make the adjustment, Gwinnett could, but would not be required to, terminate the merger agreement and the merger would not be completed.

Alternatively, assume that United’s average closing price increased 15% from $32.33 to $37.18 and that the concurrent change in the average price per share of the peer group increased 12%. In that case, the aggregate merger consideration would have increased from the $210,493,434 value on February 5, 2007 to $233,944,805. United would then have the right to adjust the merger consideration because the percentage increase in the United stock price is greater than 10% and the percentage change in the United stock price is greater than the percentage change in the average price per share of the peer group. United could elect to decrease the merger consideration by an amount equal to 3% of the value of the stock consideration. In this example, 3% is the difference between the percentage change in the stock price and the percentage change in the peer group stock price, which is less than the difference between the percentage change in the United stock price and 10%. This decrease would cause the total merger consideration to decrease to $228,424,055. Gwinnett would then have the right to terminate the merger agreement because of the adjustment and the merger would not be completed. If United elected not to make the adjustment, the merger agreement would not terminate.

This summary highlights selected information regarding the merger consideration adjustment and termination provisions in the merger agreement. For a more complete description of these terms, you should carefully read the Agreement and Plan of Reorganization included in Appendix A to these materials. In addition, we urge you to obtain current information on the market value of United shares. See “Summary — Markets for Common Stock” on page 7.

The Merger Agreement

The material features of the merger agreement are summarized below:

Effective Date

The merger agreement provides that the merger will be effective upon the approval of the Agreement and Plan of Reorganization by the shareholders of Gwinnett and the filing of the Certificate of Merger reflecting the merger with the Secretary of State of the State of Georgia.

The merger and the bank merger have been approved by the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation and the Department of Banking and Finance of the State of Georgia. Management of United and Gwinnett anticipate that the merger will become effective during the second quarter of 2007.

Terms of the Merger

If Gwinnett shareholders approve the merger and subject to required regulatory approvals, Gwinnett will be merged with and into United. In connection with the merger, Gwinnett shareholders will receive United common stock or cash or a combination of both in exchange for their Gwinnett common stock, subject to adjustment and proration as previously described. United shareholders will continue to hold their existing United common stock.

-19-

If, prior to the merger closing, the outstanding shares of United common stock or Gwinnett common stock are increased through a stock dividend, stock split, subdivision, recapitalization, or reclassification of shares, or are combined into a lesser number of shares by reclassification, reverse stock split, recapitalization, reduction of capital or other transaction, the number of shares of United common stock and/or cash to be delivered pursuant to the merger in exchange for a share of Gwinnett common stock will be proportionately adjusted.

If the merger is completed, Gwinnett will be merged with and into United. Following the merger, the articles of incorporation, bylaws, corporate identity, and existence of United will not be changed, and Gwinnett will cease to exist as a separate entity. Following the merger, Gwinnett’s subsidiary, First Bank of the South, will be merged with and into United Community Bank, Blairsville, Georgia, a wholly-owned Georgia bank subsidiary of United, and United Community Bank will be the surviving bank.

Registration of United Common Stock

As a condition to the merger, United agreed to register with the Securities and Exchange Commission the shares of United common stock to be exchanged for shares of Gwinnett common stock and to maintain the effectiveness of such registration through the issuance of such shares in connection with the closing of the merger. However, such registration will not cover resales of United common stock by any former holders of Gwinnett common stock, and United is under no obligation to maintain the effectiveness of such registration, or to prepare and file any post-effective amendments to such registration, after the issuance of such shares in connection with the closing of the merger.

Gwinnett Option and SAR Holders

Each Gwinnett option holder has agreed not to exercise his or her options prior to the closing of the merger. In exchange, United has agreed to pay the holder of each option $72.8865 in cash less the exercise price of each option. United has also agreed to pay the holder of each Gwinnett stock appreciation right, which we refer to as a SAR, $72.8865 in cash less the exercise price of each SAR.

Termination and Conditions of Closing

The merger agreement may be terminated at any time either before or after approval of the merger agreement by the shareholders of Gwinnett, but not later than the effective date of the merger:

(1)

by either party, if a material adverse change in the financial condition or business of the other party has occurred, or if material loss or damage to the other party’s properties or assets has occurred, which change, loss or damage materially affects or impairs such party’s ability to conduct its business;

(2)

by either party, if the other party has not substantially complied with, or substantially performed, the terms, covenants or conditions of the merger agreement, and such non-compliance has not otherwise been waived;

(3)

by either party, in the event of a material breach by the other party of any covenant, agreement or obligation contained in the merger agreement which breach has not been cured within 20 days after the giving of written notice of the breach or, if such breach is not capable of being cured within 20 days, the breaching party has not begun to cure such breach within 20 days after such written notice;

(4)

by either party, if the terminating party learns of any facts or conditions not disclosed by the other party in the merger agreement, or by United if it learns of any facts or conditions not disclosed by Gwinnett in its financial statements or disclosure memorandum, or by Gwinnett if it learns of any facts or conditions not disclosed by United in its SEC reports, which facts or conditions were required to be disclosed, and which materially and adversely affects such business, properties, assets, or earnings or the ownership, value or continuance thereof;

-20-

(5)

by either party, if any action, suit or proceeding is instituted or threatened against either party seeking to restrain, prohibit or obtain substantial damages in respect of the merger agreement or the consummation of the transactions, which, in the good faith opinion of the terminating party makes consummation of the transactions inadvisable;

(6)

by either party, if the merger has not occurred on or before July 31, 2007;

(7)

by United, if the holders of more than 5% of the outstanding shares of Gwinnett common stock elect to exercise statutory dissenters’ rights;

(8)

by either party, if the Gwinnett shareholders do not approve the merger agreement; or

(9)

by Gwinnett, as described in “— Merger Consideration Adjustment and Termination Rights” on page 18;

Gwinnett must pay to United a termination fee of $7.5 million, if, while a competing offer for the acquisition of Gwinnett by a party other than United is outstanding or after such an offer has been accepted by Gwinnett:

either party terminates the agreement because the Gwinnett shareholders did not approve the merger;

Gwinnett terminates the agreement other than pursuant to either (1)-(4) listed above; or

United terminates the agreement pursuant to either (2)-(5) listed above.

The following summarizes the required conditions of closing:

the accuracy of the representations and warranties of all parties contained in the merger agreement and related documents as of the date when made and the effective date;

the performance of all agreements and the satisfaction of all conditions required by the merger agreement;

the delivery of officers’ certificates, secretary’s certificates, and legal opinions to Gwinnett and United by the other;

the execution of an agreement by each director and executive officer of Gwinnett, pursuant to which each of them agrees: (i) to recommend, subject to any applicable fiduciary duty, to Gwinnett shareholders approval of the merger; (ii) to vote the capital stock of Gwinnett owned or controlled by them in favor of the merger; (iii) to transfer or assign shares of United common stock, received by them in connection with the merger only in compliance with the 1933 Securities Exchange Act, applicable state securities laws and the rules and regulations promulgated under either; and (iv) with respect to directors only, to not compete with United for a period of two years after the closing date of the merger.

approval of the merger by at least a majority of the shares held by Gwinnett shareholders;

approvals of governmental authorities, and the expiration of any regulatory waiting periods;

-21-

effectiveness of the registration statement of United relating to the shares of United common stock to be issued to Gwinnett shareholders in the merger, of which this document forms a part;

the receipt by United of a letter from Mauldin & Jenkins Certified Public Accounts, LLC with respect to Gwinnett’s unaudited financial statements from December 31, 2006 through the date of the most recent monthly financial statements available in the ordinary course of business; and

the issuance of certificate of merger by the Secretary of State of the State of Georgia.

Surrender of Certificates and Election of Consideration

After the effective date of the merger, each holder of Gwinnett common stock (as of that date) will be required to deliver the certificates representing such holder’s shares of Gwinnett common stock to United’s exchange agent, Illinois Stock Transfer, in order to receive payment of the consideration from United in connection with the merger. Each holder of Gwinnett common stock must complete and return the enclosed election form by or at the special shareholders meeting to be held on June 1, 2007 indicating his, her or its preference as to the proportion of United common stock and/or cash he, she or it wishes to receive upon delivery of his, her or its shares of Gwinnett common stock.

Although each Gwinnett shareholder may elect to receive all cash or all stock, an aggregate of no more than 306,137 shares of Gwinnett common stock may be exchanged for cash and an aggregate of no more than 2,524,764 shares of Gwinnett common stock may be exchanged for United common stock. Accordingly, if the aggregate cash elections are greater than the maximum, each cash election will be reduced pro rata based on the amount that the aggregate cash elections exceed the maximum. Alternatively, if the aggregate stock elections are greater than the maximum, each stock election will be reduced pro rata based on the amount that the aggregate stock elections exceed the maximum. If a holder does not make an election by or at the special shareholders meeting to be held on June 1, 2007, the holder will be treated as though it elected to receive cash unless cash has been fully subscribed by the electing Gwinnett shareholders, in which event such holder will be treated as if he, she or it elected stock.

After delivering shares of Gwinnett common stock, the holder will receive either 2.2545 shares of United common stock, or a cash payment of $72.8865, without interest per share of Gwinnett common stock that such holder owned on the effective date of the merger. In lieu of a fractional share, a cash payment, without interest, will be paid for any fractional interest in United common stock.

Until a holder delivers Gwinnett common stock to United, the holder may not receive payment of any dividends or other distributions on shares of United common stock into which his, her, or its shares of Gwinnett common stock have been converted, if any, and may not receive any notices sent by United to its shareholders with respect to those shares.

Required Shareholder Approval

The holders of a majority of the outstanding shares of Gwinnett common stock entitled to vote at the special meeting must approve the merger agreement for the merger to be completed. Abstentions from voting and broker non-votes will be included in determining whether a quorum is present and will have the effect of a vote against the merger agreement.

As of May 1, 2007, the record date for determining the shareholders entitled to notice of and to vote at the special meeting, the outstanding voting securities of Gwinnett consisted of 2,830,901 shares of Gwinnett common stock, with each registered holder of Gwinnett common stock being entitled to one vote per share. All of the directors, executive officers and 5% shareholders of Gwinnett have agreed to vote their shares in favor of the merger. Gwinnett’s directors, executive officers and 5% shareholders own 1,228,697 shares, or 43.40%, of Gwinnett common stock (excluding options).

-22-

Potential New Director

Under the terms of the merger agreement, after the closing of the merger United plans to increase the size of its Board from 11 members to 12 and appoint John D. Stephens, the current chairman of the board of directors of Gwinnett, to the board of directors of United. Mr. Stephens, age 66, has served as the chairman of the board of directors of Gwinnet and its bank subsidiary, First Bank of the South, since May 2000. Mr. Stephens is also the president and chief executive officer of Stephens Rock & Dirt, a position he has held since 2001.

As a director of United, Mr. Stephens will receive an annual retainer of $20,000 and a separate meeting fee of $3,000 for each board meeting he attends in 2007. The annual retainer and meeting fees are payable in cash or may be deferred pursuant to United’s Deferred Compensation Plan. In addition to the retainer and meeting fees, United reimburses non-employee directors for their travel expenses incurred in attending meetings of the board of directors or its committees, as well as for fees and expenses incurred in attending director education seminars and conferences. Directors do not receive any stock option or other equity awards nor any other personal benefits.

Expenses

All expenses incurred by United in connection with the merger, including all fees and expenses of its agents, representatives, counsel and accountants and the fees and expenses related to filing these materials and all regulatory applications with state and federal authorities will be paid by United. All expenses incurred by Gwinnett in connection with the merger agreement, including all fees and expenses of its agents, representatives, counsel and accountants will be paid by Gwinnett. The cost of reproducing and mailing these materials will be shared by the parties, with each party paying 50%.

Conduct of Business of Gwinnett Pending Closing

The merger agreement provides that, pending consummation of the merger, Gwinnett will, except with the written consent of United:

conduct its business in the ordinary course, without the creation of any indebtedness for borrowed money other than deposits and ordinary and customary accounts and credit arrangements;

maintain its properties and assets in good operating condition, ordinary wear and tear excepted;

maintain and keep in full force and effect all required insurance;

preserve its capital structure and make no change in its authorized or issued capital stock or other securities, and grant no right or option to purchase or otherwise acquire any of its capital stock or securities;

not pay cash dividends other than cash dividends payable prior to the effective date of closing not to exceed, in the aggregate, $3.80 per share of Gwinnett common stock to record holders as of February 5, 2007;

-23-

not redeem, purchase or otherwise acquire, directly or indirectly, any of its capital stock;

make no amendment to its articles of incorporation or bylaws, and preserve its corporate existence and powers;

acquire no business, corporation, partnership, association or other entity or division thereof, and no assets which are material, in the aggregate, to it;

not sell, mortgage, lease, buy or otherwise acquire, transfer or dispose of any real property or interest therein, or any tangible or intangible asset (other than in the ordinary course of business);

make no change in its banking and safe deposit arrangements;

not enter into, renew or cancel any material contracts;

maintain all books and records in the usual, regular and ordinary course;

file all reports required to be filed with any regulatory or governmental agencies, and deliver copies of such reports to United promptly after they are filed; and

adopt no new severance plan and grant no severance or termination payments to any officer, director or employee, other than in accordance with existing agreements or the agreements that are conditions to the closing of the merger.

In addition, the merger agreement provides that Gwinnett will promptly advise United, orally and in writing, of any change or event having, or which the Gwinnett management believes could have, a material adverse effect on the assets, liabilities, business, operations or financial condition of Gwinnett.

Interests of the Directors and Officers of Gwinnett in the Merger

Except as set forth below, no director or officer of Gwinnett, or any of their associates, has any direct or indirect material interest in the merger other than owning shares of Gwinnett common stock which will be converted in the merger into United common stock and cash. United and Gwinnett do not anticipate that the merger will result in any material change in compensation to employees of Gwinnett other than as set forth below.

Glenn S. White, President and Chief Executive Officer of Gwinnett will terminate his employment agreement with Gwinnett and has entered into a settlement agreement with United for a payment of three times the sum of his current base salary, average annual bonus of the three most recent years and annual automobile allowance, or $939,550, as required by his existing employment agreement upon his termination following change in control of Gwinnett and reduced to prevent such payment from being an amount that would be considered an “excess parachute payment” under the Internal Revenue Code.

Mr. White has entered into a new employment agreement with United for a rolling three-year term that provides for a payment of an amount equal to three times the sum of his base salary then in effect, an amount equal to his average annual bonus of the three most recent years and his monthly automobile allowance multiplied by twelve, subject to any reduction necessary to prevent such payment from being considered an “excess parachute payment”, if, within six months following a change of control of United, either Mr. White terminates his employment or United terminates Mr. White other than for cause. The agreement also provides that, if Mr. White is terminated at any time by United without cause, Mr. White will receive (i) his base salary for a period of thirty-six months, and (ii) an amount equal to two times the average annual bonus paid to Mr. White for the three most recent fiscal years. Additionally, if Mr. White terminates his employment from United with cause he will be entitled to receive his base salary for a period of the lesser of thirty-six months following the effective date of the termination or the remaining term of the agreement. United will also grant Mr. White 10,000 shares of restricted stock, which will vest on the fifth anniversary of the closing of the merger, and options to purchase 25,000 shares. The options vest as follows: 50% on the third anniversary, 25% on the fourth anniversary and 25% on the fifth anniversary of the closing of the merger.

-24-

Steven W. Williams, President of First Bank of the South and Executive Vice-President of Gwinnett will terminate his employment agreement with Gwinnett and has entered into a settlement agreement with United for a payment of two times the sum of his current base salary, average annual bonus of the three most recent years and annual automobile allowance, or $443,467, as required by his existing employment agreement upon his termination following change in control of Gwinnett.

Mr. Williams has entered into a new employment agreement with United for a rolling two-year term that provides for a payment of an amount equal to two times the sum of his base salary then in effect, an amount equal to his average annual bonus of the three most recent years and his monthly automobile allowance multiplied by twelve, subject to any reduction necessary to prevent such payment from being considered an “excess parachute payment”, if, within six months following a change of control of United, either Mr. Williams terminates his employment or United terminates Mr. Williams other than for cause. The agreement also provides that, if Mr. Williams is terminated at any time by United without cause, Mr. Williams will continue to receive his base salary for a period of twenty-four months. Additionally, if Mr. Williams terminates his employment from United with cause he will be entitled to receive his base salary for a period of the lesser of twenty-four months following the effective date of the termination or the remaining term of the agreement. United will also grant Mr. Williams 7,000 shares of restricted stock, which will vest on the fifth anniversary of the closing of the merger, and options to purchase 17,500 shares. The options vest as follows: 50% on the third anniversary, 25% on the fourth anniversary and 25% on the fifth anniversary of the closing of the merger.

Andrew R. Pourchier, Executive Vice President, Chief Financial Officer and Secretary of Gwinnett, has entered into a one year consulting agreement with United and will terminate his employment agreement with Gwinnett for a payment of two times the sum of his current base salary, average annual bonus of the three most recent years and annual automobile allowance, or $442,467, as required by his existing employment agreement upon his termination following a change in control of Gwinnett.

At the closing of the merger, four other Gwinnett officers will terminate their respective employment agreement with Gwinnett and have entered into a settlement agreement with United for aggregate payments of $972,667, as required by their existing employment agreements upon their respective termination following a change in control of Gwinnett. Each of these officers have entered into an employment agreement with United that provides for a payment upon their respective termination following a change in control.

In exchange for a payment by United, twelve Gwinnett lending officers have entered into non-competition agreements with United that will prohibit the officers from competing with United after the closing of the merger if their employment is terminated in exchange for aggregate payments of $700,000.

-25-

United has agreed to provide to officers and employees of Gwinnett who continue employment with United or its subsidiaries employee benefits under employee benefit plans, on terms and conditions substantially similar to those currently provided to similarly situated United officers and employees.

United has agreed to appoint John D. Stephens, chairman of the board of directors of Gwinnett, to the board of directors of United following the closing of the merger.

Differences in Legal Rights Between Shareholders of Gwinnett and United

Following the merger you will no longer be a Gwinnett shareholder and, if you receive shares of United following the merger, your rights as a shareholder will no longer be governed by Gwinnett’s articles of incorporation and bylaws. You will be a United shareholder and your rights as a United shareholder will be governed by United’s articles of incorporation and bylaws. Your former rights as a Gwinnett shareholder and your new rights as a United shareholder are different in certain ways, including the following:

Composition of Board of Directors

Gwinnett’s board of directors consists of 15 members, while United’s consists of 11 members.

Removal of Directors

The bylaws of Gwinnett provide that directors may be removed with or without cause, upon the affirmative vote of the holders of a majority of the issued and outstanding shares entitled to vote in an election of Directors.

The articles of incorporation of United provide that directors may be removed only for cause and only upon the affirmative vote of the holders of two-thirds of the issued and outstanding shares entitled to vote on the removal.

Approval of Business Transactions

Neither the articles of incorporation nor bylaws of Gwinnett require any supermajority approval of business transactions.

Neither the articles of incorporation nor bylaws of United require any supermajority approval of business transactions generally. The articles of incorporation of United provide that in order to engage in a merger, consolidation, sale or transfer or disposition of all or substantially all of the assets of United, sale of $1 million or more in securities, a plan of liquidation, or any other transaction with any holder of 10% or more of the issued and outstanding shares of United that would increase the percentage ownership of such shareholder, such transaction must be approved by either a resolution adopted by at least three-fourths of the directors then in office, or the affirmative vote of the holders of at least 75% of the outstanding shares of common stock of United and the separate affirmative vote of at least 75% of the outstanding shares of common stock, excluding those shares held by such shareholder.

Amendments to Articles of Incorporation and Bylaws

Gwinnett’s articles of incorporation provide that action by the shareholders with respect to bylaws shall be taken by an affirmative vote of a majority of all shares entitled to elect Directors, and action by the Board of Directors with respect to bylaws shall be taken by an affirmative vote of a majority of all Directors then holding office. The shareholder may provide by resolution that any bylaw provision repealed, amended, adopted or altered by them may not be repealed, amended, adopted or altered by the Board of Directors.

-26-

The articles of incorporation of United provide that its articles of incorporation may be amended to increase its authorized shares by a majority vote of the outstanding shares. Otherwise, its articles of incorporation and bylaws may be amended only by the affirmative vote of holders of two-thirds of the shares of United capital stock then issued and outstanding and entitled to vote.

Securities Exchange Act Reporting

United is subject to filing requirements under the Securities Exchange Act. These filing requirements are both periodic and transaction-based obligations whereby United discloses certain information to the Securities and Exchange Commission, and this information is subsequently made available to the public.

Gwinnett is not subject to any of the filing requirements with the Securities and Exchange Commission.

Dividends

Pursuant to the terms of the merger agreement, Gwinnett declared a cash dividend of $3.80 per share (which includes a regular cash dividend of $1.55 per share) to record holders as of February 5, 2007 payable on March 12, 2007. Gwinnett declared cash dividends of $1.45 per share in 2006, $1.35 per share in 2005 and $1.25 per share in 2004.

Accounting Treatment

The merger will be accounted for as a purchase for financial reporting and accounting purposes. After the merger, the results of operations of Gwinnett will be included in the consolidated financial statements of United. The merger consideration will be allocated based on the fair values of the assets acquired and the liabilities assumed. Any excess of cost over fair value of the net tangible and identified intangible assets of Gwinnett acquired will be recorded as goodwill. Any identified intangible asset may be amortized by charges to operations under generally accepted accounting principles.

Resales of United Common Stock by Directors, Executive Officers and Shareholders of Gwinnett

Although United, through these materials, will register the United common stock to be issued in the merger under the Securities Act of 1933, the former directors, executive officers, and 10% or greater shareholders of Gwinnett and certain other affiliates of United (as defined in Rule 405 of the Securities Act) may not resell the United common stock received by them unless those sales are made pursuant to an effective registration statement under the Securities Act, or under Rules 144 and 145 of the Securities Act, or another exemption from registration under the Securities Act. Rules 144 and 145 limit the amount of United common stock or other equity securities of United that those persons may sell during any three-month period, and require that certain current public information with respect to United be available and that the United common stock be sold in a broker’s transaction or directly to a market maker in United common stock.

-27-

Regulatory Approvals

The Board of Governors of the Federal Reserve System has approved the merger. In determining whether to grant that approval, the Federal Reserve considered the effect of the merger on the financial and managerial resources and future prospects of the companies and banks concerned and the convenience and needs of the communities to be served.

The Georgia Department of Banking and Finance has also approved the merger. The Department of Banking and Finance’s review of the application did not include an evaluation of the proposed transaction from the financial perspective of the individual shareholders of Gwinnett. Further, no shareholder should construe an approval of the application by the Department of Banking and Finance to be a recommendation that the shareholders vote to approve the proposal. Each shareholder entitled to vote should evaluate the proposal to determine the personal financial impact of the completion of the proposed transaction. Shareholders not fully knowledgeable in such matters are advised to obtain the assistance of competent professionals in evaluating all aspects of the proposal including any determination that the completion of the proposed transaction is in the best financial interest of the shareholder.

Rights of Dissenting Shareholders

Georgia law confers rights upon shareholders of corporations organized under Georgia law, such as Gwinnett, in certain circumstances, to demand payment for the fair value of all or a portion of their shares, and it establishes procedures for the exercise of those rights. These shareholder rights are referred to within this document as “dissenters’ rights”.

In general, if the merger is completed, under Article 13 of the Georgia Business Corporation Code, a Gwinnett shareholder who dissents from the merger, and who otherwise complies with the provisions of Article 13, is entitled to demand and receive payment in cash of an amount equal to the fair value of all, but not less than all, of such shareholder’s shares of Gwinnett common stock.

For the purpose of determining the amount to be received in connection with the exercise of statutory dissenters’ rights under the Georgia Business Corporation Code, Georgia law provides that the fair value of a dissenting Gwinnett shareholder’s common stock equals the value of the shares immediately before the effective date of the merger, excluding any appreciation or depreciation in anticipation of the merger.

A dissenting shareholder of Gwinnett must exercise dissenters’ rights with respect to all of the shares owned of record by such shareholder, other than those shares registered in the dissenting shareholder’s name but beneficially owned by another person. Shares registered in the name of a dissenting shareholder but beneficially owned by another person, may be excluded from a dissenting shareholder’s dissent only if the dissenting shareholder notifies Gwinnett in writing of the name and address of each person on whose behalf dissenters’ rights are being asserted and the number of shares owned beneficially by such person.

-28-

A Gwinnett shareholder who choosing to dissent from the merger and to receive payment in cash of the fair value of shares of Gwinnett common stock owned by such shareholder in accordance with the requirements of the Georgia Business Corporation Code must:

deliver to Gwinnett, prior to the time the shareholder vote on the merger agreement is taken, a written notice of such shareholder’s intent to demand payment for those shares registered in the dissenting shareholder’s name if the merger is completed; and

not vote those shares in favor of the merger agreement.

Any filing of a written notice of intent to dissent with respect to the merger should be sent to: Andrew R. Pourchier, Executive Vice President, Chief Financial Officer and Secretary, Gwinnett Commercial Group, Inc., 2230 Riverside Parkway, Lawrenceville, Georgia 30043. A vote against the merger agreement alone will not satisfy the requirements for compliance with Article 13 of the Georgia Business Corporation Code. A shareholder who wishes to dissent from the merger must, as an initial matter, separately comply with all of applicable conditions listed above.

Within ten days after the vote of Gwinnett shareholders is taken at the special meeting, Gwinnett will provide to each shareholder who timely submitted a written notice of intent to dissent, and who did not vote in favor of the merger at the special meeting, a dissenters’ notice that:

states where the dissenting shareholder must send a payment demand, and where and when the certificates for the dissenting shareholder’s shares, if any, are to be deposited;

sets a date by which Gwinnett must receive the dissenting shareholder’s payment demand; and

is accompanied by a copy of Article 13 of the Georgia Business Corporation Code.

Following receipt of the dissenters’ notice from Gwinnett, each dissenting Gwinnett shareholder must deposit Gwinnett share certificates representing the shares subject to the dissent with Gwinnett, or its successor and demand payment from Gwinnett in accordance with the terms of the dissenters’ notice. A dissenting shareholder who does not deposit those share certificate(s) and demand payment from Gwinnett by the date set forth in the dissenters’ notice will forfeit any right to payment under Article 13 of the Georgia Business Corporation Code.

Within ten days after the later of the date that the vote of Gwinnett shareholders is taken at the special meeting, or the date on which Gwinnett receives a payment demand, Gwinnett will send a written offer to each shareholder who complied with the provisions set forth in the dissenters’ notice to pay each such shareholder an amount that Gwinnett estimates to be the fair value of those shares, plus accrued interest. The offer of payment will be accompanied by:

Gwinnett’s balance sheet as of the end of a fiscal year ending not more than 16 months before the date of making an offer, an income statement for that year, a statement of changes in shareholders’ equity for that year, and the latest available interim financial statements, if any;

an explanation of how any interest was calculated;

a statement of the dissenting shareholder’s right to demand payment of a different amount under Section 14-2-1327 of the Georgia Business Corporation Code; and

a copy of Article 13 of the Georgia Business Corporation Code.

A dissenting shareholder choosing to accept Gwinnett’s offer of payment must do so by written notice to Gwinnett within 30 days after receipt of Gwinnett’s offer of payment. A dissenting shareholder not responding to that offer within the 30-day period will be deemed to have accepted the offer of payment. Gwinnett must make payment to each shareholder who responds to the offer of payment within 60 days after the making of the offer of payment, or the effective date of the merger, whichever is later. Upon payment, the dissenting shareholder will cease to have any interest in such shares of Gwinnett common stock.

-29-

If a dissenting shareholder does not accept, within 30 days after Gwinnett’s offer, the estimate of fair value in payment for such shares and interest due thereon and demands payment of some other estimate of the fair value of the shares and interest due thereon, then Gwinnett, within 60 days after receiving the payment demand of a different amount from a dissenting shareholder, must file an action in the Superior Court in Gwinnett County, Georgia, requesting that the fair value of those shares be determined. Gwinnett must make all dissenting shareholders whose demands remain unsettled parties to the proceeding. If Gwinnett does not commence the proceeding within that 60-day period, it will be required to pay each dissenting shareholder whose demand remains unsettled the amount demanded by the dissenting shareholder.

Gwinnett urges its shareholders to read all of the dissenter’s rights provisions of the Georgia Business Corporation Code, which are reproduced in full in Appendix B to these materials and which are incorporated herein by reference.

Material Federal Income Tax Consequences of the Merger and Opinion of Tax Counsel

Consideration Received for Gwinnett Common Stock

Gwinnett has received an opinion from Kilpatrick Stockton, LLP to the effect that, assuming the merger is completed in accordance with the terms of the merger agreement:

the merger and the issuance of shares of United common stock in connection with the merger, as described in the merger agreement, will constitute a tax-free reorganization under Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended;

no gain or loss will be recognized by Gwinnett as a result of the merger;

no gain or loss will be recognized by holders of Gwinnett common stock upon the exchange of Gwinnett common stock solely for United common stock as a result of the merger;

if pursuant to the merger a Gwinnett shareholder exchanges all of his or her shares of Gwinnett common stock for a combination of United stock and cash, the Gwinnett shareholder will generally recognize gain (but not loss) in an amount equal to the lesser of (i) the amount of gain realized (i.e., the excess of the sum of the amount of cash, but not cash received in lieu of a fractional share, and the fair market value of the United common stock received pursuant to the merger over such shareholder’s adjusted tax basis in its shares of Gwinnett common stock surrendered), and (ii) the amount of cash (but not cash in lieu of a fractional share) received pursuant to the merger. Any recognized gain will generally be long-term capital gain if the Gwinnett shareholder’s holding period with respect to the Gwinnett common stock surrendered is more than one year. If, however, the cash received has the effect of the distribution of a dividend, the gain would be treated as a dividend to the extent of the holder’s ratable share of Gwinnett’s accumulated earnings and profits as calculated for federal income tax purposes;

gain or loss will be recognized pursuant to Section 302 of the Internal Revenue Code of 1986, as amended, by Gwinnett common stockholders upon their receipt of solely cash for their shares of Gwinnett common stock, including cash received (i) as a result of a cash election; (ii) in lieu of fractional shares of United common stock, and (iii) upon their exercise of dissenters’ rights;

-30-

the aggregate tax basis of United common stock received by shareholders of Gwinnett pursuant to the merger will be the same as the tax basis of the shares of Gwinnett common stock exchanged therefore, (i) decreased by any portion of such tax basis allocated to fractional shares of United common stock that are treated as redeemed by United, (ii) decrease by the amount of cash received by a shareholder in the merger (other than cash received with respect to fractional shares), and (iii) increased by the amount of gain recognized by a shareholder in the merger (other than gain recognized with respect to fractional shares);

the holding period of the shares of United common stock received by the shareholders of Gwinnett will include the holding period of the shares of Gwinnett common stock exchanged, provided that the common stock of Gwinnett is held as a capital asset on the date of the consummation of the merger; and

as a result of the subsidiary merger of First Bank of the South into United Community Bank, no gain or loss shall be recognized to any of First Bank of the South, United Community Bank, Gwinnett, United or holders of Gwinnett common stock.

Consideration Received for Gwinnett Options and SARs

Holders of Gwinnett options and/or SARs issued to the holder in connection with their employment by Gwinnett will recognize ordinary income upon their receipt of cash in exchange for or cancellation of each option or SAR, and may be subject to payroll tax withholding on such payment. Holders of Gwinnett options or warrants received other than in connection with their employment by Gwinnett will recognize ordinary income or capital gain (or loss) upon the receipt of cash in exchange for or cancellation of such option or warrant depending on a variety of individual circumstances, including how long such options or warrants were held and the circumstances under which they were granted. No opinion has been provided by Kilpatrick Stockton regarding the character of such income or gain resulting from the receipt of cash with respect to such options or warrants, and such holders are advised to consult with their own tax advisors as to any tax consequences of the exchange of their options or warrants.

No ruling will be requested from the Internal Revenue Service with respect to any Federal income tax consequences of the merger.

The preceding discussion relates to the material federal income tax consequences of the merger to Gwinnett shareholders generally. You are advised to consult your own tax advisors as to any state, local, or other tax consequences of the merger.

Opinion of Gwinnett’s Financial Advisor

Gwinnett retained Burke Capital Group, L.L.C. to act as its financial advisor in connection with a possible business combination, and Burke acted as financial advisor to Gwinnett in connection with its proposed merger with United and participated in certain of the negotiations leading to the merger agreement. In connection with Burke’s engagement, Gwinnett asked Burke to evaluate the fairness of the merger consideration to Gwinnett’s stockholders from a financial point of view. At the February 5, 2007 meeting of the Gwinnett board to evaluate the merger, Burke delivered to the board its oral and written opinion that, based upon and subject to various matters set forth in its opinion, the merger consideration was fair to Gwinnett’s stockholders from a financial point of view. At this meeting, Gwinnett’s board voted to approve the merger and subsequently executed the merger agreement. Burke has consented to the inclusion of its opinion in these materials.

THE FULL TEXT OF BURKE’S WRITTEN OPINION IS ATTACHED AS APPENDIX C TO THESE MATERIALS. THE OPINION OUTLINES MATTERS CONSIDERED AND QUALIFICATIONS AND LIMITATIONS ON THE REVIEW UNDERTAKEN BY BURKE IN RENDERING ITS OPINION. THE DESCRIPTION OF THE OPINION SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE OPINION. WE URGE YOU TO READ THE ENTIRE OPINION CAREFULLY IN CONNECTION WITH YOUR CONSIDERATION OF THE PROPOSED MERGER.

BURKE’S OPINION SPEAKS ONLY AS OF THE DATE OF THE OPINION. THE OPINION WAS DIRECTED TO THE GWINNETT BOARD AND IS DIRECTED ONLY TO THE FAIRNESS OF THE MERGER CONSIDERATION TO GWINNETT SHAREHOLDERS FROM A FINANCIAL POINT OF VIEW. IT DOES NOT ADDRESS THE UNDERLYING BUSINESS DECISION OF GWINNETT TO ENGAGE IN THE MERGER OR ANY OTHER ASPECT OF THE MERGER AND IS NOT A RECOMMENDATION TO ANY GWINNETT SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE SHAREHOLDER MEETING WITH RESPECT TO THE MERGER, OR ANY OTHER MATTER.

In connection with rendering its February 5, 2007 opinion, Burke reviewed and considered, among other things:

The merger agreement and certain of the schedules in the related disclosure memorandum;

Certain publicly available financial statements and other historical financial information of Gwinnett and United that it deemed relevant;

Projected earnings estimates for Gwinnett for the years ending December 31, 2007 through 2011 that are not publicly available, prepared by and reviewed with senior management of Gwinnett and the views of senior management regarding Gwinnett’s business, financial condition, results of operations and future prospects;

Internal financial and operating information with respect to the business, operations and prospects of Gwinnett furnished to Burke by Gwinnett that is not publicly available;

The reported prices and trading activity of United common stock and compared those prices and activity with other publicly-traded companies that Burke deemed relevant;

The pro forma financial impact of the merger on United’s ability to complete a transaction from a regulatory standpoint with an emphasis on the pro forma capital ratios, based on assumptions determined by senior management of Gwinnett and Burke;

-32-

The financial terms of other recent business combinations in the commercial banking industry, to the extent publicly available;

The current market environment generally and the banking environment in particular; and

Such other information, financial studies, analyses and investigations and financial, economic and market criteria as it considered relevant.

Gwinnett’s Board of Directors did not limit the investigations made or the procedures followed by Burke in giving its opinion.

In performing its reviews and analyses and in rendering its opinion, Burke assumed and relied upon the accuracy and completeness of all the financial information, analyses and other information that was publicly available or otherwise furnished to, reviewed by or discussed with it and further relied on the assurances of management of Gwinnett and United that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. Burke was not asked to and did not independently verify the accuracy or completeness of such information and it did not assume responsibility or liability for the accuracy or completeness of any of such information. Burke did not make an independent evaluation or appraisal of the assets, the collateral securing assets or the liabilities, contingent or otherwise, of Gwinnett or United or any of their respective subsidiaries, or the ability to collect any such assets, nor was it furnished with any such evaluations or appraisals. Burke is not an expert in the evaluation of allowances for loan losses and it did not make an independent evaluation of the adequacy of the allowance for loan losses of Gwinnett or United, nor did it review any individual credit files relating to Gwinnett or United. With Gwinnett’s consent, Burke assumed that the respective allowances for loan losses for both Gwinnett and United were adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. In addition, Burke did not conduct any physical inspection of the properties or facilities of Gwinnett or United. Burke is not an accounting firm and it relied on the reports of the independent accountants of Gwinnett and the directors of United for the accuracy and completeness of the financial statements furnished to it.

Burke’s opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of its opinion. Burke assumed, in all respects material to its analysis, that all of the representations and warranties contained in the merger agreement and all related agreements are true and correct, that each party to such agreements will perform all of the covenants required to be performed by such party under such agreements and that the conditions precedent in the merger agreement are not waived. Burke also assumed that there has been no material change in Gwinnett’s and United’s assets, financial condition, results of operations, business or prospects since the date of the last financial statements made available to them, that Gwinnett and United will remain as going concerns for all periods relevant to its analyses.

In rendering its February 5, 2007 opinion, Burke performed a variety of financial analyses. The following is a summary of the material analyses performed by Burke, but is not a complete description of all the analyses underlying Burke’s opinion. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Burke believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Burke’s comparative analyses described below is identical to Gwinnett or United and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of Gwinnett or United and the companies to which they are being compared.

-33-

The earnings projections used and relied upon by Burke in its analyses were based upon internal projections of Gwinnett. Burke assumed for purposes of its analyses that such performance would be achieved. Burke expressed no opinion as to such financial projections or the assumptions on which they were based. The financial projections furnished to Burke by Gwinnett were prepared for internal purposes only and not with a view towards public disclosure. These projections, as well as the other estimates used by Burke in its analyses, were based on numerous variables and assumptions which are inherently uncertain and, accordingly, actual results could vary materially from those set forth in such projections.

In performing its analyses, Burke also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Gwinnett, United and Burke. The analyses performed by Burke are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. Burke prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Gwinnett board at the February 5, 2007 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Burke’s analyses do not necessarily reflect the value of Gwinnett’s common stock or United’s common stock or the prices at which Gwinnett’s or United’s common stock may be sold at any time.

Summary of Proposed Merger

Burke reviewed the financial terms of the proposed transaction whereby the holders of Gwinnett common stock shall be entitled to receive, in exchange for their shares of Gwinnett stock, 2.2545 shares of United common stock, $72.8865 in cash or a combination thereof subject to the limitations as described in the merger agreement. Holders of outstanding options and SARs shall receive cash, equal to $72.8865 minus the applicable exercise price per option or SAR. Based upon the terms of the merger agreement and United’s closing stock price of $32.96 on February 2, 2007, Burke calculated merger consideration of $220,089,447 and a special cash dividend of $6,369,527 for an aggregate transaction valuation of $226,458,974 or $76.24 per fully diluted Gwinnett share on February 5, 2007, the date of the Gwinnett board meeting.

-34-

Utilizing Gwinnett’s December 31, 2006 unaudited financial information, Burke calculated the following ratios:

Deal Value Considerations:			Deal Multiples:
Aggregate Price/Fully Diluted Share	$	76.24	Transaction Value/ 2006 Net Income	19.05	x
Merger Consideration for Common Shares	$	209,924,226	Transaction Value / Book Value	2.86	x
Merger Consideration for Outstanding Opinions / SARs	$	10,165,221	Transaction Value / Tangible Book Value	3.35	x
Aggregate Cash Dividend⁽¹⁾	$	6,369,527	Transaction Value / Leveraged Book Value⁽²⁾	4.42	x
Total Transaction Value	$	226,458,974	Core Deposit Premium	33.6	%

*	Deal multiples based on December 31, 2006 unaudited financial result.

(1)	Represents a $2.25 special cash dividend to all record Gwinnett shareholders as of December 31, 2006.

(2)	Assumes tangible equity to tangible assets of 7%. Excess equity valued at 1.0x.

The fully diluted share count is based upon Gwinnett’s 2,830,901 outstanding common shares, 208,321 outstanding options to purchase common shares at a weighted average exercise price of $28.72 and 22,000 stock appreciation rights at a weighted average exercise price of $29.06. This analysis assumes no options are exercised prior to closing. Any exercise of options prior to closing would change the fully diluted share count and would slightly change the per share consideration, but not the total transaction valuation.

Analysis of Gwinnett

Selected Peer Group Analysis. Burke used publicly available information to compare selected financial information for Gwinnett and a group of selected financial institutions. The group consisted of Gwinnett and 68 banks, which we refer to as the “Gwinnett Peer Group”. The Gwinnett Peer Group consisted of selected Southeast banks with assets between $500 million and $1.5 billion and having earned at least 1.00% on average assets for the trailing twelve months.

The analysis compared the median performance of the Gwinnett Peer Group, based upon the latest publicly available financial data, to Gwinnett’s December 31, 2006 unaudited financial results. The table below sets forth the comparative data.

	Revenues						Earnings												Capital Implications						Asset Quality			Employee Productivity		Asset Growth
	Net Interest Margin			Noninterest Income/Average Assets			Efficiency			ROAA ⁽¹⁾			ROAE ⁽²⁾			Pre-Provision, Pre-Tax Margin			Equity / Assets			Asset Utilization			NPAs/Total Assets⁽³⁾			Assets / Employee		1-yr

Gwinnett’s performance is above the Gwinnett Peer Group.

Analysis of Selected Merger Transactions

Southeastern Transactions. In order to address the specific valuation considerations within the Southeastern market that Gwinnett serves, Burke selected a group of comparable Southeastern merger and acquisition transactions and compared the pricing multiples to the multiples implied by the merger consideration. Specifically, Burke selected bank merger and acquisition transactions according to the following criteria:

Merger and acquisition transactions announced after January 1, 2003.

Seller located within the Southeastern United States - AL, AR, FL, GA, LA, MS, NC, SC, TN & VA.

Seller assets between $500 million and $1.5 billion.

Seller with ROAA greater than 1.25% in the latest quarter prior to announcement.

Burke selected 10 transactions fitting the criteria listed above as being comparable to the proposed merger. The 10 comparable transactions selected included the following:

Buyer	State	Seller	State
Banco Sabadell SA	Spain	Transatlantic Holding Corp.	FL
Park National Corp.	OH	Vision Bancshares Inc.	FL
Alabama National BanCorp.	AL	PB Financial Services Crop.	GA
BB&T Corp.	NC	First Citizens Bancorp	TN
Pinnacle Financial Partners	TN	Cavalry Bancorp Inc.	TN
Synovus Financial Corp.	GA	Riverside Bancshares Inc.	GA
Liberty Bancshares Inc.	AR	Russellville Bancshares Inc.	AR
Boston Private Equity Financial	MA	Gibraltar Financial Corp.	FL
Provident Bankshares Corp.	MD	Southern Financial Bancorp	VA
Fulton Financial Corp.	PA	Resource Bankshares Corp.	VA

Burke reviewed the multiples of transaction value at announcement to last twelve months’ (“LTM”) earnings, transaction value to most recent quarterly (“MRQ”) earnings annualized, transaction value to book value, transaction value to tangible book value, transaction value to leveraged book value, and book premium to core deposits and computed high, low, mean, median, and quartile multiples and premiums for the transactions. These multiples and premiums were applied to Gwinnett’s financial information as of and for the period ended December 31, 2006 and were used to impute a transaction price. As illustrated in the following table, Burke derived an imputed range of values per share of Gwinnett’s common stock of $63.66 to $92.45 based upon the median and mean multiples of the selected Southeastern transactions.

-36-

	Median Multiple			Implied Value / Share		Gwinnett Merger Consideration
Transaction Value / LTM Earnings		19.96	x	$	79.68		19.05	x
Transaction Value / MRQ Earnings (annualized)		17.91	x	$	72.76		18.76	x
Transaction Value / Book Value		3.49	x	$	92.45		2.86	x
Transaction Value / Tangible Book Value		3.53	x	$	80.12		3.35	x
Transaction Value / Leveraged Book Value*		3.55	x	$	63.66	��	4.42	x
Tangible Book Premium / Core Deposits		26.41	%	$	64.96		33.66	%

		Average Valuation		$	75.61	$	76.24

		Implied Range		$	63.66	$	92.45

*	Assumes 7% tangible equity to tangible assets. Excess equity valued at 1.0x.

The analysis showed that the merger consideration of $76.24 per fully diluted share is within the range of values imputed by the mean and median multiples of the comparable Southeastern transactions and slightly above the implied average valuation of the comparables universe.

U.S. Transactions. Burke, in addition to analyzing Southeastern transactions, selected a group of comparable U.S. merger and acquisition transactions and compared the pricing multiples to the multiples implied by the merger consideration. Specifically, Burke selected bank merger and acquisition transactions according to the following criteria:

Merger and acquisition transactions announced after January 1, 2003.

Seller located within the continental United States.

Seller assets between $500 million and $1.5 billion.

Seller with ROAA greater than 1.25% in the latest quarter prior to announcement.

Southwest Bankcorp. Of Texas	TX	Klein Bancshares Inc.	TX
Provident Bankshares Corp.	MD	Southern Financial Bancorp	VA

Burke reviewed the multiples of transaction value at announcement to LTM earnings, transaction value to MRQ earnings annualized, transaction value to book value, transaction value to tangible book value, transaction value to leveraged book value and book premium to core deposits and computed high, low, mean, median, and quartile multiples and premiums for the transactions. These multiples and premiums were applied to Gwinnett’s financial information as of and for the period ended December 31, 2006 and were used to impute a transaction price. As illustrated in the following table, Burke derived an imputed range of values per share of Gwinnett’s common stock of $65.85 to $89.10 based upon the median and mean multiples of the selected U.S. transactions.

-38-

	Median Multiple			Implied Value / Share		Gwinnett Merger Consideration
Transaction Value / LTM Earnings		19.73	x	$	78.79		19.05	x
Transaction Value / MRQ Earnings (annualized)		17.62	x	$	71.61		18.76	x
Transaction Value / Book Value		3.36	x	$	89.10		2.86	x
Transaction Value / Tangible Book Value		3.53	x	$	80.05		3.35	x
Transaction Value / Leveraged Book Value*		3.70	x	$	65.85		4.42	x
Tangible Book Premium / Core Deposits		28.05	%	$	67.49		33.66	%

		Average Valuation		$	75.20	$	76.24

		Implied Range		$	65.85	$	89.10

*	Assumes 7% tangible equity to tangible assets. Excess equity valued at 1.0x.

The analysis showed that the merger consideration of $76.24 per fully diluted share is within the range of values imputed by the mean and median multiples of the comparable U.S. transactions and slightly above the implied average valuation of the comparables universe.

Discounted Cash Flow Analysis

Using a discounted cash flow analysis, Burke estimated the present value of the future stream of earnings and dividends that Gwinnett could produce based upon an internal earnings and balance sheet forecast for 2007 through 2011. Burke performed discounted cash flow analyses based upon terminal values to both earnings and tangible equity.

In order to derive the terminal value of Gwinnett’s earnings stream beyond 2010, Burke assumed terminal value multiples ranging from 15.0x to 18.0x of fiscal year 2011 net income. The dividend streams and terminal values were then discounted to present values using different estimated discount rates (ranging from 14.0% to 16.0%) chosen to reflect different assumptions regarding the required rates of return to holders or prospective buyers of Gwinnett common stock. This discounted cash flow analysis indicated a value range between $55.43 and $70.35 per share of Gwinnett common stock.

The value of the consideration offered by United to Gwinnett in the merger is $76.24 per fully diluted share of Gwinnett common stock on, which is above the range of values imputed from the discounted cash flow analysis.

Contribution Analysis

Burke computed the contribution of United and Gwinnett to various elements of the pro forma entity’s income statement, excluding estimated cost savings and operating synergies, balance sheet and franchise. The following table compares the pro forma ownership in the combined company, assuming a hypothetical 100% transaction, to each company’s respective contribution to each element of the analysis.

-39-

	Contribution
	Gwinnett			United
Pro Forma Fully Diluted Ownership		13.26	%		86.74	%

*Earnings (000’s)*
2006 Actual Earnings		14.73	%		85.27	%
2007 Estimated Earnings		13.58	%		86.42	%

*Balance Sheet (12/31/2006) (000’s)*
Loans, net		9.00	%		91.00	%
Assets		8.68	%		91.32	%
Deposits		9.17	%		90.83	%
Equity		11.38	%		88.62	%
Tangible Equity		13.07	%		86.93	%

*Branches*		5.15	%		94.85	%

The contribution analysis indicated that the pro forma ownership of United common stock issuable to Gwinnett shareholders assuming a hypothetical 100% stock transaction in the merger was greater than loans, assets, deposits, equity, tangible equity and branches and slightly less than earnings contributed to United by Gwinnett.

Analysis of United

Selected Peer Group Analysis

Burke used publicly available information to compare selected financial information for United and a group of selected financial institutions. The group consisted of United and 31 bank holding companies, which we refer to as the United Peer Group. The United Peer Group consisted of selected publicly traded U.S. banks with assets between $5 billion and $10 billion.

Relative Stock Price Performance

Burke analyzed the price performance of United common stock from February 1, 2006 to February 2, 2007 and compared that performance to the performance of the S&P Bank Index (WCB: BIX) and the S&P 500 Index (WCB: GSPC) over the same period. The S&P Bank Index is a market cap weighted price index composed of 25 major financial company stocks. The S&P Bank Index is not traded but is quoted under the symbol “BIX”. This analysis indicated the following cumulative changes in price over the period:

United:	15.00%
S&P Bank Index:	11.12%
S&P 500 Index:	12.15%

Burke noted that United’s stock price outperformed both indices from February 1, 2006 to February 2, 2007, the prior trading day to Burke’s oral and written opinion.

Other Factors And Analyses

Burke took into consideration various other factors and analyses, including: historical market prices and trading volumes for United’s common stock; movements in the common stock of selected publicly-traded companies and movements in the S&P Bank Index.

Information Regarding Burke

Pursuant to a letter agreement dated December 13, 2006, Gwinnett paid Burke a fee of $50,000 upon the execution of the merger agreement. In addition, Gwinnett has agreed to pay Burke a financial advisory fee that will fluctuate based upon the ultimate value received by Gwinnett at the closing of the merger, including both the merger consideration, consideration paid to the holders of Gwinnett options and SARs, and the 2007 cash dividend that Gwinnett intends to pay prior to closing of the merger. As of the date of the announcement of the merger, the fee payable to Burke at the closing of the merger would have been $2,214,190. In addition, Gwinnett has agreed to reimburse Burke for its reasonable out-of-pocket expenses and to indemnify Burke and certain related persons against certain liabilities arising out of or in conjunction with its rendering of services under its engagement, including certain liabilities under the federal securities laws.

Burke is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Burke is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

The authorized capital stock of United currently consists of 100,000,000 shares of common stock, $1.00 par value per share and 10,000,000 shares of preferred stock, $1.00 par value per share. As of May 1, 2007, 43,064,895 shares of common stock were issued and outstanding, exclusive of 51,864 shares issuable to participants in United’s Deferred Compensation Plan and 3,086,625 shares reserved for issuance upon the exercise of outstanding options and vesting of restricted stock. At that date, United had 32,200 shares of Series A Non-Cumulative Preferred Stock issued and outstanding.

Common Stock

All voting rights are vested in the holders of the common stock. Each holder of common stock is entitled to one vote per share on any issue requiring a vote at any meeting. The shares do not have cumulative voting rights. Subject to the right of holders of United’s Series A Non-Cumulative Preferred Stock to receive dividends, all shares of United common stock are entitled to share equally in any dividends that United’s board of directors may declare on United common stock from sources legally available for distribution. The determination and declaration of dividends is within the discretion of United’s board of directors. Upon liquidation, holders of United common stock are entitled to receive on a pro rata basis, after payment or provision for payment of all debts and liabilities of United, and after all distributions payments are made to holders of United’s Series A Non-Cumulative Preferred Stock, all assets of United available for distribution, in cash or in kind.

The outstanding shares of United common stock are, and the shares of United common stock to be issued by United in connection with the merger will be, duly authorized, validly issued, fully paid, and nonassessable.

Preferred Stock

United is authorized to issue 10,000,000 shares of preferred stock, issuable in specified series and having specified voting, dividend, conversion, liquidation, and other rights and preferences as United’s board of directors may determine. The preferred stock may be issued for any lawful corporate purpose without further action by United shareholders. The issuance of any preferred stock that has conversion rights might have the effect of diluting the interests of United’s other shareholders. In addition, shares of preferred stock could be issued with certain rights, privileges, and preferences, which would deter a tender or exchange offer or discourage the acquisition of control of United.

United’s board of directors has designated 287,411 of the 10,000,000 authorized shares of preferred stock as “Series A Non-Cumulative Preferred Stock”, of which 32,200 remain outstanding. The Series A stock has a stated value of $10.00 per share, and holders of Series A stock are entitled to a preferential annual dividend of 6%, payable quarterly on each January 1, April 1, July 1 and October 1. The declaration of dividends with respect to the Series A stock is within the discretion of United’s board of directors.

-42-

In addition, holders of the Series A stock are entitled to receive, on a pro rata basis, distributions upon liquidation prior to any payment by United to the holders of its common stock, in an amount equal to the stated value per share of the Series A stock, plus any accrued but unpaid dividends. The Series A stock has no voting rights, except as required under the Georgia Business Corporation Code, and is not convertible into shares of common stock or other securities of United. United may, at its option, redeem all or part of the Series A stock outstanding by paying cash for such shares in an amount equal to the stated value per share, plus any accrued but unpaid dividends.

Interest is payable semi-annually in arrears in cash on March 31 and September 30 of each year. The notes are callable at par on September 30, 2010, and September 30 of each year thereafter until maturity on September 30, 2015. The notes are general unsecured obligations of United, subordinated to all existing and future secured and senior indebtedness, and payment of principal of the notes may be accelerated only in the case of bankruptcy, insolvency, receivership, conservatorship or reorganization of United or one of United’s bank subsidiaries.

Trust Preferred Securities

United has five wholly owned statutory trusts, which issued guaranteed preferred interests in United’s junior subordinated deferrable interest debentures. The debentures represent the sole asset of each of the trusts. These debentures qualify as Tier I capital under Federal Reserve Board guidelines. All of the common securities of the trusts are owned by United. United has entered into contractual arrangements which, taken collectively, fully and unconditionally, guarantee payment of: (1) accrued and unpaid distributions required to be paid on the securities; (2) the redemption price with respect to any securities called for redemption by the respective trust; and (3) payments due upon a voluntary or involuntary dissolution, winding up or liquidation of the respective trust. The following is a description of each trust preferred security.

10.60% Trust Preferred Securities

In September 2000, United formed a wholly owned Connecticut statutory business trust, United Community Statutory Trust I (“United Statutory Trust”), which issued $5 million of guaranteed preferred beneficial interests in United’s junior subordinated deferrable interest debentures. The proceeds from the issuance of the securities were used by United Statutory Trust to purchase $5.2 million of junior subordinated debentures of United, which carry a fixed interest rate of 10.60%. The securities accrue and pay distributions semiannually at a fixed rate of 10.60% per annum of the stated liquidation value of $1,000 per capital security and are mandatorily redeemable upon maturity of the debentures on September 7, 2030, or upon earlier redemption as provided in the indenture. United has the right to redeem the debentures purchased by United Statutory Trust in whole or in part, on or after September 7, 2010. As specified in the indenture, if the debentures are redeemed prior to maturity, the redemption price will be the principal amount, any accrued but unpaid interest, plus a premium ranging from 5.3% in 2010 to .53% beginning in 2019.

Certain Provisions of United’s Articles of Incorporation and Bylaws Regarding Change of Control

Ability to Consider Other Constituencies

United’s articles of incorporation permit its board of directors, in determining what is believed to be in the best interest of United and its shareholders, to consider the interests of its employees, customers, suppliers and creditors, the communities in which its offices and establishments are located and all other factors that they consider pertinent, in addition to considering the effects of any actions on United and its shareholders. This provision permits United’s board of directors to consider numerous judgmental or subjective factors affecting a proposal, including some non-financial matters, and on the basis of these considerations may oppose a business combination or some other transaction which, viewed exclusively from a financial perspective, might be attractive to some, or even a majority, of its shareholders.

Amendments to Articles of Incorporation and Bylaws

United’s articles of incorporation specifically provide that neither the articles of incorporation nor the bylaws of United may be amended without the affirmative vote the holders of two-thirds of the shares issued and outstanding and entitled to vote thereon, except for provisions relating to increasing the number of authorized shares of common and preferred stock of United. This provision could allow the holders of 33.4% of the outstanding capital stock of United to exercise an effective veto over a proposed amendment to the articles or bylaws, despite the fact that the holders of 66.6% of the shares favor the proposal. This provision protects, among other things, the defensive measures included in United’s articles of incorporation and bylaws by making more difficult future amendments to the articles of incorporation and bylaws that could result in the deletion or revision of such defensive measures.

Supermajority Approval of Interested Business Combinations

United’s articles of incorporation provide that if a proposed business combination between United and any interested shareholder is not approved by three-fourths of all directors of United then in office, the business combination must be approved by the affirmative vote of the holders of at least 75% of the outstanding shares of United’s common stock, including the affirmative vote of the holders of at least 75% of the outstanding shares of common stock held by shareholders other than the interested shareholder. This provision may discourage attempts by other corporations or groups to acquire control of United, without negotiation with management, through the acquisition of a substantial number of shares of United’s stock followed by a forced merger. This provision may also enable a minority of the shareholders of United to prevent a transaction favored by a majority of the shareholders, and may discourage tender offers or other non-open market acquisitions of United’s common stock because of the potentially higher vote requirements for shareholder approval of any subsequent business combination. Additionally, in some circumstances, United’s board of directors could, by withholding its consent to such a transaction, cause the 75%/75% shareholder vote to be required to approve a business combination, thereby enabling management to retain control over the affairs of United and their present positions with United.

-45-

Removal of Directors

United’s articles of incorporation provide that a member of United’s board of directors may only be removed for cause, and only upon the affirmative vote of two-thirds of the outstanding shares of capital stock of United entitled to vote thereon. This provision may prevent a significant shareholder from avoiding board scrutiny of a proposed business combination by merely removing directors with conflicting views, and may encourage individuals or groups who desire to propose takeover bids or similar transactions to negotiate with the board of directors. However, outside of the context of an acquisition attempt, it may serve as an impediment to a more legitimate need to remove a director.

In addition, in certain aspects of its banking business, First Bank of the South also competes with credit unions, small loan companies, consumer finance companies, brokerage firms, insurance companies, money market funds and other financial institutions.

technological changes may increase competitive pressures and increase costs.

We believe these forward-looking statements are reasonable, but we caution that the foregoing list of factors is not exclusive and that you should not place undue reliance on these forward-looking statements, because the future results and shareholder values of United following completion of the merger may differ materially from those expressed or implied by these forward-looking statements. We do not intend to update any forward-looking statement, whether written or oral, relating to the matters discussed in these materials.

Such adjustment, if any, shall be reflected in the payment of the adjusted Merger Consideration as provided in accordance with the Merger Agreement.

WHEREAS, the authorized capital stock of GCG consists of 12,000,000 shares of voting Common Stock, no par value per share, of which 2,830,901 shares are issued and outstanding (the “GCG Stock”) and 2,000,000 shares of nonvoting common stock, no par value per share, none of which is issued and outstanding; and

WHEREAS, the respective Boards of Directors of the Constituent Corporations deem it advisable and in the best interests of each such corporation and its shareholders that GCG merge with and into United, with United being the surviving corporation; and

WHEREAS, the respective Boards of Directors of the Constituent Corporations, by resolutions duly adopted, have approved and adopted this Agreement, and the Board of Directors of GCG, by resolution duly adopted, has directed that this Agreement be submitted to the shareholders of GCG for their approval; and

WHEREAS, United has agreed to issue shares of United Stock which shareholders of GCG will be entitled to receive, according to the terms and conditions contained herein, on or after the Effective Date (as defined herein) of the merger provided for herein.

NOW, THEREFORE, for and in consideration of the premises and the mutual agreements herein contained, and other good and valuable consideration, the receipt and adequacy of which as legally sufficient consideration are hereby acknowledged, the parties hereto have agreed and do hereby agree, as follows:

1.	Merger.

Pursuant to and with the effects provided in the applicable provisions of Article 11 of the Georgia Business Corporation Code, as amended (Chapter 2 of Title 14 of the Official Code of Georgia), GCG (sometimes referred to as the “Merged Corporation”) shall be merged with and into United (the “Merger”). United shall be the surviving corporation (the “Surviving Corporation”) and shall continue under the name “United Community Banks, Inc.” On the Effective Date (as defined herein) of the Merger, the individual existence of the Merged Corporation shall cease and terminate.

A-33

2.	Actions to be Taken.

The acts and things required to be done by the Georgia Business Corporation Code in order to make this Agreement effective, including the submission of this Agreement to the shareholders of the Merged Corporation and the filing of the certificate of merger in Georgia, relating hereto in the manner provided in said laws, shall be attended to and done by the proper officers of the Constituent Corporations with the assistance of counsel as soon as practicable.

3.	Effective Date.

The Merger shall be effective upon the approval of this Agreement by the shareholders of the Merged Corporation and the filing of the certificate of merger in Georgia, relating hereto in the manner provided in the Georgia Business Corporation Code (the “Effective Date”).

4.	Articles of Incorporation and Bylaws of the Surviving Corporation.

(a) The Amended and Restated Articles of Incorporation of United, as heretofore amended, shall on the Effective Date be the Articles of Incorporation of the Surviving Corporation.

(b) Until altered, amended or repealed, as therein provided, the Amended and Restated Bylaws of United as in effect on the Effective Date shall be the Bylaws of the Surviving Corporation.

5.	Manner and Basis of Converting Shares of Capital Stock; Capital Structure of the Surviving Corporation.

Unless amended pursuant to Section 11.8 of that certain Agreement and Plan of Reorganization of even date herewith by and between GCG and United (the “Acquisition Agreement”), the manner and basis of converting the shares of capital stock of each of the Constituent Corporations into shares of the Surviving Corporation shall be as follows:

(a) In the Merger, the holders of GCG Stock shall be entitled to elect to receive, in exchange for their shares of GCG Stock, shares of United Stock, cash or a combination thereof, in the amounts specified by such holders in accordance with the provisions of Section 5(b) below, and each share of GCG Stock outstanding immediately prior to the Effective Date shall, by virtue of the Merger, be converted on the Effective Date into fully paid and nonassessable shares of United Stock and/or cash as follows, subject to any adjustments occurring after the date hereof as contemplated by Section 5(d) below:

(1) 2.2545 shares of United Stock for each outstanding share of GCG Stock (the “Stock Exchange Ratio”);

(2) $72.8865 in cash, without interest, per share of GCG Stock (the “Cash Exchange Rate”); or

(3) any combination thereof;

provided, however, that no more than 306,137 shares of GCG Stock may be exchanged for cash (the “Maximum Cash Election”) and no more than 2,524,764 shares of GCG Stock may be exchanged for United Stock (the “Maximum Stock Election”) and any shares of GCG Stock elected to be exchanged for cash above the Maximum Cash Election or stock above the Maximum Stock Election shall be subject to proration as provided in Section 5(b) below.

A-34

(b) At the same time that the notice of special meeting of GCG shareholders (the “Special Meeting”) is first mailed to GCG shareholders, a form of election shall also be mailed to each GCG shareholder (the date of such form of election being referred to herein as the “Mailing Date”). Each GCG shareholder shall indicate thereon his, her or its preference as to the proportion of United Stock and/or cash which he, she or it desires to receive in exchange for his, her or its GCG Stock, and shall return the form to the Secretary of GCG prior to the date of the Special Meeting. If a GCG shareholder does not make such an election by the date of the Special Meeting, such shareholder shall receive cash as set forth in Section 5(a)(2) above unless the number of shares for which cash elections have been received exceeds the Maximum Cash Election, in which case such shareholder shall receive United Stock as set forth in Section 5(a)(1) above. If holders of GCG Stock elect to receive cash for a number of shares of GCG Stock in excess of the Maximum Cash Election or elect to receive United Stock for an aggregate number of shares of GCG Stock in excess of the Maximum Stock Election, then the number of shares exchanged for cash or United Stock, respectively, by each shareholder so electing will be reduced such that the amount of shares exchanged for cash equals the Maximum Cash Election and the amount of shares exchanged for United Stock equals the Maximum Stock Election, based on the ratio that the number of shares elected to be exchanged by such shareholder bears to the total number of shares elected to be exchanged for cash or United Stock by all GCG shareholders. To the extent a GCG shareholder does not receive the number of shares of United Stock determined pursuant to Section 5(a) above for each share of GCG Stock such shareholder elected to be exchanged for United Stock or the amount in cash determined pursuant to Section 5(a) above for each share of GCG Stock such shareholder elected to be exchanged for cash due to the proration provided in this Section 5(b), such shareholder shall be entitled to receive the amount in cash determined pursuant to Section 5(a) above for each remaining share of GCG Stock not exchanged for United Stock or the number of shares of United Stock determined pursuant to Section 5(a) for each remaining share of GCG Stock not exchanged for cash, respectively.

(c) Upon the Effective Date, all rights with respect to GCG Stock pursuant to stock options (the “GCG Stock Options”) and stock appreciation rights (the “GCG SARs”) granted by GCG which are outstanding at the Effective Date, whether or not exercisable, shall be converted on the Effective Date, subject to any adjustments occurring after the date hereof as contemplated by Section 5(d) below, into an amount in cash, without interest, equal to the result of $72.8865 minus the applicable “Exercise Price” or “Strike Price” for such GCG Stock Options or GCG SARs, respectively, as defined in the applicable stock option or stock appreciation right agreement.

(d) If either party should change the number of its outstanding shares as a result of a stock split, stock dividend, or similar recapitalization with respect to such shares prior to the Effective Date then the shares to be issued hereunder to holders of GCG Stock shall be proportionately adjusted.

(e) No scrip or fractional share certificates of United Stock shall be issued in connection with the Merger and an outstanding fractional share interest will not entitle the owner thereof to vote, to receive dividends or to have any of the rights of a shareholder with respect to such fractional interest. In lieu of any fractional interest, there shall be paid in cash, without interest, an amount (computed to the nearest cent) equal to such fraction multiplied by $32.33.

(f) As soon as practicable after the Effective Date, each holder as of the Effective Date of any of the shares of GCG Stock to be converted by such holder as elected by such holder as above provided, upon presentation and surrender of the certificates representing such shares to United, shall be entitled to receive in exchange therefor a certificate representing the number of shares of United Stock, and cash, to which such shareholder shall be entitled according to the terms of this Agreement. Until such surrender, each such outstanding certificate which prior to the Effective Date represented GCG Stock shall be deemed for all corporate purposes to evidence ownership of the number of shares of United Stock into which the same shall have been converted as elected by such holder as above provided, the right to receive cash by such holder as above provided, and the right to receive payment for fractional shares.

A-35

(g) Upon the Effective Date, each share of United Stock issued and outstanding immediately prior to the Effective Date shall continue unchanged and shall continue to evidence a share of common stock of the Surviving Corporation.

(h) Except as otherwise provided in this Section 5, in no event shall the total number of shares of United Stock issued in connection with the Merger exceed 5,692,082.

6. Termination of Separate Existence.

Upon the Effective Date, the separate existence of the Merged Corporation shall cease and the Surviving Corporation shall possess all of the rights, privileges, immunities, powers and franchises, as well of a public nature as of a private nature, of each of the Constituent Corporations; and all property, real, personal and mixed, and all debts due on whatever account, and all other choses in action, and all and every other interest of or belonging to or due to each of the Constituent Corporations shall be taken and deemed to be transferred to and vested in the Surviving Corporation without further act or deed, and the title to any real estate or any interest therein, vested in either of the Constituent Corporations shall not revert or be in any way impaired by reason of the Merger. The Surviving Corporation shall thenceforth be responsible and liable for all the liabilities, obligations and penalties of each of the Constituent Corporations; and any claim existing or action or proceeding, civil or criminal, pending by or against either of said Constituent Corporations may be prosecuted as if the Merger had not taken place, or the Surviving Corporation may be substituted in its place, and any judgment rendered against either of the Constituent Corporations may thenceforth be enforced against the Surviving Corporation; and neither the rights of creditors nor any liens upon the property of either of the Constituent Corporations shall be impaired by the Merger.

7. Further Assignments.

If at any time the Surviving Corporation shall consider or be advised that any further assignments or assurances in law or any other things are necessary or desirable to vest in said corporation, according to the terms hereof, the title to any property or rights of the Merged Corporation, the proper officers and directors of the Merged Corporation shall and will execute and make all such proper assignments and assurances and do all things necessary and proper to vest title in such property or rights in the Surviving Corporation, and otherwise to carry out the purposes of this Agreement.

This Agreement is subject to, and consummation of the Merger is conditioned upon, the fulfillment as of the Effective Date of each of the following conditions:

(a) Approval of this Agreement by the affirmative vote of the holders of a majority of the outstanding voting shares of GCG Stock; and

(b) All the terms, covenants, agreements, obligations and conditions of the Acquisition Agreement to be complied with, satisfied and performed on or prior to the Closing Date (as defined therein), shall have been complied with, satisfied and performed in all material respects unless accomplishment of such covenants, agreements, obligations and conditions has been waived by the party benefited thereby.

A-36

9.	Termination.

This Agreement may be terminated and the Merger abandoned in accordance with the terms of the Acquisition Agreement, at any time before or after adoption of this Agreement by the directors of either of the Constituent Corporations, notwithstanding favorable action on the Merger by the shareholders of the Merged Corporation, but not later than the issuance of the certificate of merger by the Secretary of State of the State of Georgia with respect to the Merger in accordance with the provisions of the Georgia Business Corporation Code.

Counterparts; Title; Headings.

This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same instrument.

Lawrenceville, GA 30043

Members of the Board of Directors:

Gwinnett Commercial Group, Inc. ("GCG") and United Community Banks, Inc. (“United”) are considering entering into an Agreement and Plan of Merger (the “Agreement”), dated as of the 5th day of February, 2007, whereby GCG will merge with and into United (the “Merger”), with United being the surviving corporation. Pursuant to the terms of the Agreement, holders of GCG Stock shall be entitled to elect to receive, in exchange for their shares of GCG Stock, $72.8865 in cash, 2.2545 shares of United (“United Stock”) or a combination thereof subject to the limitations as described in the Agreement. Holders of outstanding options to acquire GCG Stock (the “GCG Stock Options”) and holders of outstanding GCG stock appreciation rights (the “GCG SARs”) shall receive cash, equal to the result of $72.8865 minus the applicable exercise price for such GCG Stock Options or GCG SARs. In addition to the terms described above, record holders of GCG Stock as of December 31, 2006 shall receive a special cash dividend payable prior to closing not to exceed $2.25 per share. This cash dividend is in addition to the $1.55 regularly scheduled dividend payable in March. The terms and conditions of the Merger are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, as of the date hereof, of the Merger consideration that United will render.

Burke Capital Group, L.L.C. (“BCG”) is an investment banking firm which specializes in financial institutions in the United States. GCG has retained us to render our opinion to its Board of Directors.

In connection with this opinion, we have reviewed, among other things:

(i)	The Agreement and certain of the schedules thereto;

(ii)	Certain publicly available financial statements and other historical financial information of GCG and United that it deemed relevant;

(iii)

Projected earnings estimates for GCG for the years ending December 31, 2007 through 2011 prepared by and reviewed with senior management of GCG and the views of senior management regarding GCG’s business, financial condition, results of operations and future prospects;

(iv)	Internal financial and operating information with respect to the business, operations and prospects of GCG furnished to BCG by GCG that is not publicly available;

(v)	The reported prices and trading activity of United’s common stock and compared those prices and activity with other publicly-traded companies that BCG deemed relevant;

(vi)	The pro forma financial impact of the merger on United’s ability to complete a transaction from a regulatory standpoint, based on assumptions determined by senior management of GCG and BCG;

(vii)

The financial terms of other recent business combinations in the commercial banking industry, to the extent publicly available;

(viii)

The current market environment generally and the banking environment in particular;

(ix)	Such other information, financial studies, analyses and investigations and financial, economic and market criteria as it considered relevant.

In performing our review, we have relied upon the accuracy and completeness of the financial and other information that was available to us from public sources, that GCG and United or their respective representatives provided to us or that was otherwise reviewed. We have further relied on the assurances of management of GCG and United that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of GCG, United or any of their subsidiaries, or the collectibility of any such assets, nor have we been furnished with any such evaluations or appraisals. We did not make an independent evaluation of the adequacy of the allowance for loan losses of GCG or United, nor have we reviewed any individual credit files relating to GCG or United. We have assumed, with your consent, that the respective allowances for loan losses for both GCG and United are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. With respect to the earnings estimates for GCG and United and all projections of transaction costs, purchase accounting adjustments and expected cost savings that we reviewed with the management of GCG, BCG assumed, with your consent, that they reflected the best currently available estimates and judgments of the respective managements of the respective future financial performances of GCG and United and that such performances will be achieved. We express no opinion as to such earnings estimates or financial projections or the assumptions on which they are based. We have assumed in all respects material to our analysis that GCG and United will remain as going concerns for all periods relevant to our analyses, that all of the representations and warranties contained in the Agreement and all related agreements are true and correct, that each party to the Agreement and such other related agreements will perform all of the covenants they are required to perform thereunder and that the conditions precedent in the Agreement and such other related agreements are not waived.

Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We are expressing no opinion herein as to what the price at which GCG’s common stock may trade at any time.

We will receive a fee for our services as financial advisor to GCG and for rendering this opinion. BCG does not have an investment banking relationship with United; nor does it have any contractual relationship with United.

This opinion is directed to the Board of Directors of GCG and may not be reproduced, summarized, described or referred to or given to any other person without our prior consent.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the amount of the Merger consideration is fair from a financial point of view.
