The State Street Building Purchase of the State Street Building. On July 30, 2001, Wells Operating - ------------------------------------- Partnership, L.P. (Wells OP), a Delaware limited partnership formed to acquire, own, lease and operate real properties on behalf of Wells REIT, purchased a seven-story office building with approximately 234,668 rentable square feet located at 1200 Crown Colony Drive, Norfolk County, Quincy, Massachusetts (State Street Building). Wells OP purchased this building from Crownview, LLC (Crownview) pursuant to that certain Agreement of Purchase and Sale of Property between Crownview and Wells OP. Crownview is not in any way affiliated with Wells REIT or Wells Capital, Inc., our Advisor. The purchase price for the State Street Building was $49,563,000. Wells OP incurred acquisition expenses in connection with the purchase of the State Street Building, including attorneys' fees, recording fees, structural report and environmental report fees, and other closing costs, of approximately $69,500. Wells OP also paid approximately $126,600 to reimburse the seller for its prorated share of real estate taxes and other operating expenses.

An independent appraisal of the State Street Building was prepared by Insignia/ESG, Inc., real estate appraisers, as of July 10, 2001, pursuant to which the market value of the real property containing the leased fee interest subject to the leases described below was estimated to be $52,000,000, in cash or terms equivalent to cash. This value estimate was based upon a number of assumptions, including that the State Street Building will continue operating at a stabilized level with SSB Realty LLC, a Delaware limited liability company (SSB Realty), occupying 100% of the rentable area, and is not necessarily an accurate reflection of the fair market value of the property or the net proceeds which would result from an immediate sale of this property. Wells OP also obtained an environmental report and an engineering inspection report prior to the closing evidencing that the condition of the land and the State Street Building were satisfactory. Description of the State Street Building and Site. The State Street Building, - ------------------------------------------------- which was completed in 1990, is a seven-story office building containing approximately 234,668 rentable square feet located on an 11.22 acre tract of land. The building is constructed using a steel frame with a reinforced concrete foundation. The exterior walls are made of primarily precast concrete with insulated glass windows in aluminum frames. The interior walls consist of painted gypsum board. In addition, there are four elevators and approximately 854 parking spaces. The State Street Building is located at 1200 Crown Colony Drive in Crown Colony Office Park in Quincy, Massachusetts, approximately 10 miles southwest of downtown Boston. Crown Colony Office Park contains high quality office buildings and is one of the most desirable parks in the south Boston market. The strength of the office market in this area is evidenced by the extensive office development near other interchanges along Route 128 in the Quincy/Braintree area. The property is well located in terms of proximity to Boston, and accessability to all of the other major highway systems that serve the city and the surrounding area because of its immediate access to a highway interchange and to public transportation. The State Street Building is leased entirely to SSB Realty. The SSB Realty Lease. The entire 234,668 rentable square feet of the State - -------------------- Street Building is currently under a lease agreement with SSB Realty. The landlord's interest in the SSB Realty lease was assigned to Wells OP at the closing. The current term of the lease is 10 years, which commenced on February 1, 2001, and expires on March 31, 2011. SSB has the right to extend the term of this lease for one additional five year period at the then-current fair market rental rate. In addition, the base operating costs and the base taxes will be adjusted for the extended term to reflect the actual operating costs and taxes for the preceding calendar year. SSB Realty is a wholly owned subsidiary of State Street Corporation, a Massachusetts corporation (State Street). State Street, a guarantor of the SSB Realty lease, is a world leader in providing financial services to investment managers, corporations, public pension funds, unions, not-for-profit organizations and individuals. State Street's capabilities range from investment research and professional investment management to trading and brokerage services to fund accounting and administration. With over 17,000 employees, offices in 23 countries, and serving clients in 55 different countries, State Street has over $6 trillion in assets under custody and $711 billion in assets under management. For the fiscal year ended December 31, 2000, State Street reported net income of approximately $595 million on revenues of approximately $3.6 billion, and a net worth, as of December 31, 2000, of approximately $3.26 billion. The base rent payable for the remainder of the SSB Realty lease is as follows: Lease Year Annual Rent Monthly Rent - --------------------------------------------------------------------------- April 1, 2001 - January 30, 2004 $6,922,706 $576,892 - --------------------------------------------------------------------------- February 1, 2004 - January 30, 2007 $7,274,708 $606,226 - --------------------------------------------------------------------------- February 1, 2007 - March 31, 2011 $7,861,378 $655,115 - --------------------------------------------------------------------------- 2

Pursuant to the SSB Realty lease, Wells OP is obligated to provide SSB Realty an allowance of up to approximately $2,112,000 for tenant, building and architectural improvements. Under the SSB Realty lease, SSB Realty is required to pay its proportionate share of taxes relating to the State Street Building and all operating costs incurred by the landlord in maintaining and operating the State Street Building, including, but not limited to, garbage and waste disposal, janitorial service and window cleaning, snow removal, security, insurance, water and sewer charges, wages, salaries and employee benefits of all employees engaged in the operation, maintenance and management of the building, indoor and outdoor landscaping, utilities and repairs, replacements and general maintenance. Wells OP, as the landlord, will be responsible, at tenant's expense, for maintaining the common areas of the building, the roof, foundation, exterior walls and windows, load bearing items and the central heating, ventilation and air conditioning, electrical, mechanical and plumbing systems of the building. Property Management Fees. Wells Management Company, Inc. (Wells Management), an - ------------------------ affiliate of Wells REIT and our Advisor, has been retained to manage and lease the State Street Building. Wells REIT shall pay management and leasing fees to Wells Management in the amount of 4.5% of gross revenues from the State Street Building, subject to certain limitations. Initial Transaction under the Section 1031 Exchange Program As described in Supplement No. 2 dated April 25, 2001 to the prospectus dated December 20, 2000, Wells Development Corporation, an affiliate of our Advisor, has developed a program (Section 1031 Exchange Program) involving the acquisition of income-producing commercial properties and the formation of a series of single member limited liabilities companies (Wells Exchange) for the purpose of facilitating the resale of co-tenancy interests in such real estate properties to persons (1031 Participants) who are looking to invest the proceeds from a sale of real estate held for investment into another real estate investment for purposes of qualifying for like-kind exchange treatment under Section 1031 of the Internal Revenue Code. The initial transaction in the Section 1031 Exchange Program involves the acquisition by Wells Exchange and resale of co-tenancy interests in the Ford Motor Credit Complex. The Ford Motor Credit Complex consists of two connecting office buildings containing 167,434 rentable square feet located in Colorado Springs, Colorado currently under a triple-net lease with Ford Motor Credit Company, a wholly-owned subsidiary of Ford Motor Company, which is the world's largest automobile finance company with more than 10 million customers in 40 countries. Wells Exchange is currently engaged in the offer and sale of co- tenancy interests in the Ford Motor Credit Complex to 1031 Participants. As a part of the initial transaction in the Section 1031 Exchange Program, in consideration for the payment of a Take Out Fee in the amount of $137,500, and following approval of the potential property acquisition by our board of directors, Wells OP entered into a Take Out Purchase and Escrow Agreement relating to the Ford Motor Credit Complex. Pursuant to the terms of the Take Out Purchase and Escrow Agreement, Wells OP is obligated to acquire, at Wells Exchange's cost ($839,694 in cash plus $832,060 of assumed debt for each 7.63358% co-tenancy interest), any co-tenancy interests in the Ford Motor Credit Complex which remain unsold on October 16, 2001. The obligations of Wells OP under the Take Out Purchase and Escrow Agreement are secured by reserving against Wells OP's existing line of credit with Bank of America, N.A. (Interim Lender). If, for any reason, Wells OP fails to acquire any of the co-tenancy interests in the Ford Motor Credit Complex which remain unsold as of October 16, 2001, or if there is otherwise an uncured default under the interim loan between Wells Exchange and the Interim Lender or Well OP's line of credit documents, the Interim Lender is authorized to draw down on Wells OP's line of credit in the amount necessary to pay the outstanding balance of the Interim Loan in full, in which event the appropriate amount of unsold co-tenancy interests in the Ford Motor Credit Complex would be deeded to Wells OP. Wells OP's maximum economic exposure in the transaction is $11,000,000, in which event Wells OP would acquire the Ford Motor Credit Complex for $11,000,000 in cash plus assumption of the first mortgage financing in the amount of $10,900,000. If Wells Exchange successfully sells 100% of the co- tenancy interests to 3

1031 Particpants, Wells OP will not acquire any interest in the Ford Motor Credit Complex. If some, but not all, of the co-tenancy interests are sold by Wells Exchange, Wells OP's exposure would be less, and it would end up owning an interest in the property in co-tenancy with 1031 Participants who had previously acquired co-tenancy interests in the Ford Motor Credit Complex from Wells Exchange. (See "Risk Factors - Section 1031 Exchange Program" contained in Supplement No. 2 dated April 25, 2001 to the prospectus dated December 20, 2000.) Management's Discussion and Analysis of Financial Condition and Results of Operation The information contained on page 98 in the "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" section of the prospectus is revised as of the date of this supplement by the deletion of the first two paragraphs of that section and the insertion of the following paragraphs in lieu thereof: We began active operations on June 5, 1998, when we received and accepted subscriptions for 125,000 shares pursuant to our initial public offering, which commenced on January 30, 1998.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To Wells Real Estate Investment Trust, Inc.: We have audited the accompanying statement of revenues over certain operating expenses for the State street bank BUILDING for the year ended December 31, 2000. This financial statement is the responsibility of management. Our responsibility is to express an opinion on this financial statement based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States. These standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of revenues over certain operating expenses is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of revenues over certain operating expenses. An audit also includes assessing the accounting principles used and significant estimates made by management as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. As described in Note 2, this financial statement excludes certain expenses that would not be comparable with those resulting from the operations of the State Street Bank Building after acquisition by the Wells Operating Partnership, L.P., a subsidiary of Wells Real Estate Investment Trust, Inc. The accompanying statement of revenues over certain operating expenses was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission and is not intended to be a complete presentation of the State Street Bank Building's revenues and expenses. In our opinion, the statement of revenues over certain operating expenses presents fairly, in all material respects, the revenues over certain operating expenses of the State Street Bank Building for the year ended December 31, 2000 in conformity with accounting principles generally accepted in the United States. /s/ ARTHUR ANDERSEN LLP Atlanta, Georgia August 1, 2001 6
