SUPPLEMENT NO. 2 DATED AUGUST 11, 2006

TO THE PROSPECTUS DATED APRIL 26, 2006

This document supplements, and should be read in conjunction with, our prospectus dated April 26, 2006 relating to our offering of 475,000,000 shares of common stock, as supplemented by supplement no. 1 dated May 16, 2006. Capitalized terms used in this supplement have the same meanings as set forth in the prospectus. The purpose of this supplement is to disclose:

Status of Our Public Offerings

We commenced our initial public offering of 785 million shares of common stock on December 1, 2003, which consisted of a 600 million-share primary offering and a 185 million-share offering under our dividend reinvestment plan. We stopped making offers under the primary offering on November 26, 2005. We raised gross offering proceeds of approximately $2.0 billion from the sale of approximately 197.1 million shares in our initial public offering, including shares sold under the dividend reinvestment plan after the primary offering had been terminated.

On November 10, 2005, we commenced our follow-on offering of 300.6 million shares of common stock. Of these shares, we are offering 300 million shares in a primary offering and 0.6 million shares under our dividend reinvestment plan. On April 14, 2006, we amended the registration statements for our follow-on offering and our initial public offering in order to offer in a combined prospectus the 300.6 million shares registered under the follow-on offering and the 174.4 million unsold dividend reinvestment plan shares registered under the initial public offering. As of August 9, 2006, we had received gross offering proceeds of approximately $517.5 million from the sale of approximately 51.8 million shares in our follow-on offering.

As of August 9, 2006, we had received aggregate gross offering proceeds of approximately $2.5 billion from the sale of approximately 248.9 million shares in our public offerings. After incurring approximately $49.6 million in acquisition fees, approximately $233.5 million in selling commissions and dealer manager fees, approximately $38.3 million in other organization and offering expenses, and funding common stock redemptions of approximately $34.8 million pursuant to the share redemption program, as of August 9, 2006, we had raised aggregate net offering proceeds available for investment in properties of approximately $2.1 billion, substantially all of which had been invested in real estate properties.

Acquisition of the 263 Shuman Boulevard Building

On July 20, 2006, we purchased a five-story office building containing approximately 354,000 rentable square feet (the “263 Shuman Boulevard Building”) for approximately $55.3 million, exclusive of closing costs. The acquisition was funded with net proceeds raised from this offering and with proceeds from our $400.0 million line of credit with Wachovia Bank, N.A. The 263 Shuman Boulevard Building is located on an approximate 15.2-acre parcel of land at 263 Shuman Boulevard in Naperville, Illinois. The 263 Shuman Boulevard Building was purchased from 263 Shuman, LLC, which is not affiliated with us or our advisor.

The 263 Shuman Boulevard Building, which was completed in 1986, is entirely leased to OfficeMax Incorporated. OfficeMax, which is traded on the New York Stock Exchange, is a provider of business-to-business and retail office products distribution. OfficeMax provides office supplies and paper, print and document services, technology products and solutions, and furniture to large, medium and small businesses and consumers. OfficeMax reported a net worth, as of April 1, 2006, of approximately $1.7 billion.

The current annual base rent payable under the OfficeMax lease, which commenced in June 2006 and expires in May 2017, is approximately $4.5 million; however, provided that OfficeMax is not in default under its lease, OfficeMax is entitled to a full abatement of its base rent and its proportionate share of taxes and a partial abatement of its proportionate share of operating expenses that would otherwise be due for the first lease year (the “Rental Concession”). OfficeMax has the right, at its option, to extend the initial term of its lease for two additional five-year periods. OfficeMax has a one-time option to terminate its lease effective in 2014 for a termination fee equal to the sum of unamortized leasing costs and the Rental Concession, plus six months of base rent and operating expenses.

We do not intend to make significant renovations or improvements to the 263 Shuman Boulevard Building in the near term. We believe that the 263 Shuman Boulevard Building is adequately insured.

Acquisition of the 11950 Corporate Boulevard Building

On August 9, 2006, we purchased a four-story office building containing approximately 227,000 rentable square feet (the “11950 Corporate Boulevard Building”) for approximately $44.0 million, exclusive of closing costs. The acquisition was funded with net proceeds raised from this offering and with proceeds from our $400.0 million line of credit with Wachovia Bank, N.A. The 11950 Corporate Boulevard Building is located on an approximate 13.2-acre parcel of land at 11950 Corporate Boulevard in Orlando, Florida. The 11950 Corporate Boulevard Building was purchased from 11950 Corporate Owner Corporation, which is not affiliated with us or our advisor.

The 11950 Corporate Boulevard Building, which was completed in 2001, is entirely leased to Siemens Westinghouse Power Corporation (“Siemens Westinghouse”). Siemens Westinghouse, a subsidiary of the German electronics and electrical engineering group Siemens AG, is headquartered in Orlando, Florida and is the regional business entity in the Americas for Siemens Power Generation’s global fossil power generation business. Siemens AG, which is traded on the New York Stock Exchange, has approximately 461,000 employees working to develop and manufacture products, design and install complex systems and projects, and tailor a wide range of services for individual requirements. Siemens AG focuses on the areas of information and communications, automation and control, power, transportation, medical, and lighting. Siemens AG reported a net worth, as of June 30, 2006, of approximately €27.8 billion. The current annual base rent payable under the Siemens Westinghouse lease, which commenced in April 2001 and expires in June 2011, is approximately $3.2 million. Siemens Westinghouse has the right, at its option, to extend the initial term of its lease for two additional five-year periods.

We do not intend to make significant renovations or improvements to the 11950 Corporate Boulevard Building in the near term. We believe that the 11950 Corporate Boulevard Building is adequately insured.

Indebtedness

As of August 9, 2006, our leverage ratio, that is, the ratio of total debt to total purchase price of real estate assets plus cash and cash equivalents, was approximately 22%. As of August 9, 2006, total indebtedness was approximately $605.4 million, which consisted of fixed-rate mortgages on certain properties of approximately $475.6 million, approximately $115.5 outstanding under our $400.0 million credit facility and approximately $14.3

million outstanding under our construction line of credit. Based on the value of our borrowing-base properties, we had approximately $284.5 million in remaining capacity under our $400.0 million line of credit with Wachovia, N.A., of which $1.4 million was pledged in the form of letters of credit for future tenant improvements and leasing costs.

Amendment to Share Redemption Program

Our board of directors has further amended our share redemption program, which enables stockholders to sell their shares to us, subject to the limitations described below. The amendment, which will become effective on September 9, 2006, grants us the discretion to redeem all shares submitted for redemption upon the death of stockholders. Set forth below is a full description of our amended share redemption program.

For Ordinary Redemptions (those that do not occur within two years of death or “qualifying disability”, as defined below), the initial price at which we will repurchase a share under the share redemption program is 91% of the price at which we sold the share. We will pay $9.10 to redeem a share issued at $10.00. This initial redemption price will remain fixed until three years after we complete our offering stage. We define the completion of our offering stage to be upon the termination of our first public equity offering that is followed by a one-year period in which we do not engage in another public equity offering. (For purposes of this definition, we do not consider a “public equity offering” to include offerings on behalf of selling stockholders or offerings related to a dividend reinvestment plan, employee benefit plan or the redemption of interests in our operating partnership).

Three years after we complete our offering stage, the redemption price for Ordinary Redemptions will equal 95% of the estimated per share value of our shares, as estimated by our advisor or another firm chosen for that purpose. We will report this redemption price in the annual report and the three quarterly reports that we publicly file with the SEC.

There are several limitations on our ability to redeem shares:

Although there is no limit on the number of shares we may redeem upon the death of stockholders, we are under no obligation to redeem such shares to the extent such redemptions would cause total redemptions to exceed the two limits set forth immediately above.

Subject to the limitations described above, we will redeem shares on the last business day of each month. Requests for redemption must be received at least five business days before a month-end redemption date in order for us to repurchase the shares that month. If we cannot purchase all shares presented for redemption, we will honor redemption requests at the applicable month-end on a pro rata basis. We will deviate from pro rata purchases in two minor ways: (i) if a pro rata redemption would result in you owning less than half of the minimum amount required by applicable state law, then we would redeem all of your shares; and (ii) if a pro rata redemption would result in you owning more than half but less than all of the amount required by applicable state law, then we would not redeem any shares that would reduce your holdings below the minimum amount. In the event that you seek the redemption of all of your shares, there is no holding-period requirement for shares purchased pursuant to our dividend reinvestment plan.

If we do not completely satisfy your redemption request at month-end because the request was not received in time or because of the restrictions on the number of shares we can redeem under the program, we will treat the unsatisfied portion of the redemption request as a request for redemption in the following month unless you withdraw the request before the next date for redemptions. You may withdraw a redemption request upon written notice to us at the address below before the date for redemption.

In several respects we treat redemptions sought within two years of a stockholder’s death or “qualifying disability” differently from Ordinary Redemptions. First, there is no requirement that the shares be outstanding for at least a year before being redeemed. Second, the redemption price equals 100% of the price at which we sold the share until three years after we complete our offering stage. At that time, the redemption price will be 100% of the price at which we sold the share or 100% of the estimate of our per share value, whichever is greater. Finally, as explained above, there is no limit on the number of shares we may redeem upon the death of stockholders.

In order for a disability to entitle a stockholder to the special redemption terms described above (a “qualifying disability”), (1) the stockholder must receive a determination of disability based upon a physical or mental condition or impairment arising after the date the stockholder acquired the shares to be redeemed, and (2) such determination of disability must be made by the governmental agency responsible for reviewing the disability retirement benefits that the stockholder could be eligible to receive (the “applicable governmental agency”). The “applicable governmental agencies” are limited to the following: (i) if the stockholder paid Social Security taxes and therefore could be eligible to receive Social Security disability benefits, then the applicable governmental agency is the Social Security Administration or the agency charged with responsibility for administering Social Security disability benefits at that time if other than the Social Security Administration; (ii) if the stockholder did not pay Social Security benefits and therefore could not be eligible to receive Social Security disability benefits, but the stockholder could be eligible to receive disability benefits under the Civil Service Retirement System (“CSRS”), then the applicable governmental agency is the U.S. Office of Personnel Management or the agency charged with responsibility for administering CSRS benefits at that time if other than the Office of Personnel Management; or (iii) if the stockholder did not pay Social Security taxes and therefore could not be eligible to receive Social Security benefits but suffered a disability that resulted in the stockholder’s discharge from military service under conditions that were other than dishonorable and therefore could be eligible to receive military disability benefits, then the applicable governmental agency is the Veteran’s Administration or the agency charged with responsibility for administering military death benefits at that time if other than the Veteran’s Administration.

Disability determinations by governmental agencies for purposes other than those listed above, including but not limited to worker’s compensation insurance, administration or enforcement of the Rehabilitation Act or Americans with Disabilities Act or waiver of insurance premiums, will not entitle a stockholder to the special redemption terms described above. Redemption requests following an award by the applicable governmental agency of disability benefits must be accompanied by: (1) the investor’s initial application for disability benefits and (2) a Social Security Administration Notice of Award, a U.S. Office of Personnel Management determination of disability under CSRS, a Veteran’s Administration record of disability-related discharge or such other documentation issued by the applicable governmental agency that we deem acceptable and demonstrates an award of the disability benefits.

We understand that the following disabilities do not entitle a worker to Social Security disability benefits:

Therefore, such disabilities will not qualify for the special redemption terms except in the limited circumstances when the investor is awarded disability benefits by the other “applicable governmental agencies” described above.

A stockholder that is a trust may only redeem on the terms available in connection with the death or disability of a stockholder if the deceased or disabled was the sole beneficiary of the trust or if the only other beneficiary of the trust was the spouse of the deceased or disabled.

Qualifying stockholders who desire to redeem their shares must give written notice to Wells Investment Securities, the dealer manager for this offering, at 6200 The Corners Parkway, Suite 250, Norcross, Georgia 30092, ATTN: Investor Services. Wells Investment Securities is responsible for all services to be performed in connection with the share redemption program, although it has outsourced clerical duties to our advisor.

Our board of directors may amend, suspend or terminate the share redemption program upon 30 days’ notice. However, under the terms of our recently amended Corporate Governance Guidelines, until a secondary market develops for shares of our common stock or our board’s decision to commence a liquidation of the Company, we may not amend the share redemption program in a way that materially adversely affects the rights of redeeming heirs without the approval of our stockholders. We will notify you of any amendment, suspension or termination of the share redemption program (i) in the annual or quarterly reports mentioned above or (ii) by means of a separate mailing, accompanied by disclosure in a current or periodic report under the Securities Exchange Act of 1934. During a public offering, we will also include this information in a prospectus supplement or post-effective amendment to the registration statement, as then required under federal securities laws.

Our share redemption program only provides stockholders a limited ability to redeem shares for cash until a secondary market develops for the shares, at which time the program will terminate. No such market presently exists, and we cannot assure you that any market for your shares will ever develop.

On June 16, 2006, in connection with the amendment to our share redemption program, we entered into an insurance agreement with an affiliate of London Life and Casualty Reinsurance Corporation, to provide us with an insurance-backed funding source for the redemption of the shares under our share redemption program in the event we receive an unusually large number of redemption requests due to the death of investors. The funding for redemptions under the share redemption program was previously funded solely from funds received from our dividend reinvestment plan. After the deductible has been met under the insurance agreement, funds will be disbursed to us, upon receipt of a share re-registration or redemption request due to the death of a stockholder.

In accordance with the insurance agreement, the share redemption program insurance proceeds will be paid to us after a quarterly adjusted deductible, currently $1.8 million for the quarter ending September 30, 2006, is met. The deductible adjusts with additional investment proceeds raised and with the changing demographics of our stockholder base (age, gender, etc.). The maximum dollar value of proceeds that we can collect under the insurance agreement is $6.0 billion in aggregate or $5.0 million for any individual redemption request. The insurance agreement has a 10-year term unless it expires earlier upon the occurrence of one of the following liquidity events: (i) the listing of our shares on a national exchange, (ii) our liquidation, or (iii) the acquisition of a majority of our shares by an unaffiliated entity or a merger in which we are not the surviving entity. We may elect to terminate the insurance agreement at any time with 30 days’ written notice, subject to a $0.1 million termination fee and possible penalty. The board has agreed to seek the approval of our stockholders prior to terminating this insurance program.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the accompanying consolidated financial statements and notes thereto contained in this supplement no. 2, as well as our consolidated financial statements and notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations for the year ended December 31, 2005 included in the prospectus. This discussion contains forward-looking statements, which can be identified with the use of forward-looking terminology such as “may,” “will, “intend” or similar words. Actual results may differ from those described in forward-looking statements. For a discussion of the factors that could cause actual results to differ from those anticipated, see “Risk Factors” in the prospectus.

We were formed on July 3, 2003. During 2004, we began acquiring real estate assets and receiving investor proceeds under our initial public offering of common stock. We continued receiving investor proceeds and investing in real estate assets through June 30, 2006. Thus, our results of operations for the three months and six months ended June 30, 2006 and June 30, 2005 reflect growing operational revenues and expenses, fluctuating interest expense, and general and administrative expenses. The increased operational revenues and expenses result from acquiring real properties, while the fluctuations in interest expense arise from using varying levels of short-term and long-term debt financing for our acquisitions. Our general and administrative expenses have declined as a percentage of total revenues for the three months and six months ended June 30, 2006, as compared to the three months and six months ended June 30, 2005, commensurate with the operational growth of the enterprise.

Liquidity and Capital Resources

Overview

From January 2004 through June 2006, we raised significant funds through the sale of our common stock under our public offerings. We primarily used the proceeds from these sales of common stock, net of offering costs and other expenses, to acquire real properties and fund certain capital improvements identified at the time of acquisition. We anticipate receiving proceeds from the sale of our common stock in this offering in the future, and investing such proceeds in future acquisitions of real properties. We also anticipate receiving proceeds from the sale of our common stock under our dividend reinvestment plan in the future, and using a significant portion of such proceeds to fund redemptions of our common stock under our share redemption program. We expect that our primary source of future operating cash flows will be cash generated from the operations of the properties currently in our portfolio and those to be acquired in the future. The amount of future dividends to be paid to our stockholders will be largely dependent upon the amount of cash generated from our operating activities, our expectations of future cash flows, and our determination of near-term cash needs for capital improvements, tenant re-leasing, redemptions of our common stock, and debt repayments.

The competition to acquire high-quality commercial office properties remains high. Timing differences arise between acquiring properties and raising capital and between making operating payments and collecting operating receipts. Accordingly, we may periodically be required to borrow funds on a short-term basis to meet our dividend payment schedule. Our primary focus, however, is to continue to maintain the quality of our portfolio. Thus, in this intensely competitive environment, we may opt to lower the dividend rather than compromise that quality or accumulate significant borrowings to meet a dividend level higher than operating cash flow would support. We will continue to carefully monitor our cash flows and market conditions and their impact on our earnings and future dividend projections.

Short-term Liquidity and Capital Resources

During the six months ended June 30, 2006, we generated net cash flows from operating activities of approximately $66.0 million, which is primarily comprised of receipts for rental income, tenant reimbursements, hotel income, and interest and other income, partially offset by payments for property operating costs, interest expense, asset and property management fees, hotel operating costs, and general and administrative expenses. From cash flows from operating activities during the six months ended June 30, 2006, we paid dividends to stockholders of approximately $63.9 million. During the six months ended June 30, 2006, we generated net cash flows from financing activities of approximately $36.0 million, primarily as a result of raising proceeds from the sale of common stock under our public offerings, net of commissions, dealer-manager fees, and other offering costs, of approximately $378.3 million, reduced by net debt repayments of approximately $258.5 million and redemptions of common stock of approximately $14.0 million. Such net cash flows from financing activities and cash on hand were used primarily to invest approximately $89.5 million in real estate and earnest money and pay acquisition fees of approximately $10.6 million. We expect to utilize residual cash and cash equivalents of approximately $34.2 million as of June 30, 2006 to satisfy current liabilities, pay future dividends, fund future acquisitions of real properties, or reduce indebtedness.

We intend to continue to generate capital from the sale of common stock in this offering and from third-party borrowings, and to use such capital primarily to fund future acquisitions of real estate. As of July 31, 2006, we held cash balances of approximately $46.2 million and had approximately $92.0 million of outstanding borrowings under the $400.0 million unsecured revolving financing facility with a syndicate of banks led by Wachovia Bank, N.A. (the “Wachovia Line of Credit”). As of July 31, 2006, after consideration of letters of credit pledged against the Wachovia Line of Credit, we had a remaining borrowing capacity of approximately $306.6 million under the Wachovia Line of Credit. Accordingly, we believe that we have adequate capacity to continue to expand our portfolio and meet our future operating cash flow needs. We expect to use substantially all of our future operating cash flow, after payment for certain capital expenditures, to pay dividends to stockholders and to use cash on hand and third-party borrowings to fund future acquisitions of real properties.

On June 2, 2006, our board of directors declared a daily dividend for stockholders of record from June 16, 2006 through September 15, 2006 in an amount equal to an annualized dividend of $0.60 per share, which is consistent with the rate of dividends declared for each quarter in 2005 and the first two quarters of 2006 on a per share basis. Such dividend will be paid during September 2006.

Long-term Liquidity and Capital Resources

We expect that our primary sources of capital over the long term will include proceeds from the sale of our common stock, proceeds from secured or unsecured borrowings from third-party lenders, and net cash flows from operations. We expect that our primary uses of capital will be for property acquisitions, either directly or through investments in joint ventures, tenant improvements, offering-related costs, operating expenses, including interest expense on any outstanding indebtedness, and dividends.

In determining how and when to allocate cash resources, we initially consider the source of the cash. We expect that substantially all future net operating cash flows, after payments for certain capital expenditures such as tenant improvements and leasing commissions, will be used to pay dividends. However, we may use other sources of cash, such as short-term borrowings, to fund dividends from time to time (see “Liquidity and Capital Resources - Overview” above). We expect to use substantially all net cash flows generated from raising equity or debt financing to fund acquisitions, certain capital expenditures identified upon acquisition, the repayment of outstanding borrowings, and the redemption of shares under the share redemption program. If sufficient equity or debt capital is not available, our future investments in real estate will be lower.

To the extent that future cash flows provided by operations are lower due to lower returns on properties, future dividends paid may be lower as well. Our cash flow from operations depends significantly on market rents and our tenants’ ability to make rental payments. We believe that the diversity of our tenant base and the concentration of creditworthy tenants in our portfolio helps to mitigate the risk of tenants defaulting on leases. However, general economic downturns, or downturns in one or more of our core markets, could adversely impact the ability of our tenants to make lease payments and our ability to re-lease space on favorable terms when leases expire. In the event of either situation, our cash flow and consequently our ability to meet capital needs, could adversely affect our ability to pay dividends in the future.

Contractual Commitments and Contingencies

As of June 30, 2006, our contractual obligations are as follows (in thousands):

Results of Operations

Overview

Our results of operations are not indicative of those expected in future periods as we expect that rental income, tenant reimbursements, operating expenses, asset management fees, depreciation, amortization, and net income will increase in future periods as a result of owning the assets we acquired during the last six months of 2005 and the first six months of 2006 for an entire period and as a result of anticipated future acquisitions of real estate assets.

We commenced our initial public offering on December 1, 2003. Following the receipt and acceptance of subscriptions for the minimum offering of $2,500,000 on January 22, 2004, we acquired 25 real properties during 2004 and the first six months of 2005. During the remainder of 2005 and the first six months of 2006, we invested in 17 additional properties, which increased our total portfolio to 42 properties as of June 30, 2006. Accordingly, the results of operations presented for the three months and six months ended June 30, 2006 and June 30, 2005 are not directly comparable.

Comparison of the three months ended June 30, 2005 versus the three months ended June 30, 2006

Rental income and tenant reimbursements increased from approximately $29.8 million and $6.0 million, respectively, for the three months ended June 30, 2005 to approximately $58.5 million and $14.5 million, respectively, for the three months ended June 30, 2006, primarily as a result of the growth in the portfolio during the last six months of 2005 and the first six months of 2006. Rental income and tenant reimbursements are expected to continue to increase in future periods, as compared to historical periods, as a result of owning the assets acquired during the last six months of 2005 and the first six months of 2006 for an entire period and future acquisitions of real estate assets.

Hotel income and hotel operating costs of approximately $6.0 million and $4.2 million, respectively, were recognized for the three months ended June 30, 2006 and reflect earnings on one hotel property located in Cleveland, Ohio, which we acquired during the fourth quarter of 2005.

Property operating costs and asset and property management fees increased from approximately $10.3 million and $2.8 million, respectively, for the three months ended June 30, 2005 to approximately $21.5 million and $6.2 million, respectively, for the three months ended June 30, 2006, primarily as a result of the growth in the portfolio during the last six months of 2005 and the first six months of 2006. Property operating costs and asset and property management fees are expected to continue to increase in future periods, as compared to historical periods, due to owning the assets acquired during the last six months of 2005 and the first six months of 2006 for an entire period and future acquisitions of additional real estate assets.

Depreciation of real estate and amortization of related lease costs increased from approximately $5.2 million and $9.6 million, respectively, for the three months ended June 30, 2005 to approximately $11.2 million and $20.0 million, respectively, for the three months ended June 30, 2006, primarily due to the acquisition of properties during the last six months of 2005 and the first six months of 2006. We expect depreciation and amortization to continue to increase in future periods, as compared to historical periods, due to future acquisitions of real estate assets.

General and administrative expenses increased from approximately $2.5 million for the three months ended June 30, 2005 to approximately $3.0 million for the three months ended June 30, 2006, primarily due to increases in salary expense reimbursements payable to Wells Capital and Wells Management Company, Inc. (“Wells Management”) as a result of acquiring additional properties during the last six months of 2005 and the first six months of 2006. General and administrative expenses as a percent of total revenues decreased from approximately 7% for the three months ended June 30, 2005 to approximately 4% for the three months ended June 30, 2006.

Interest expense increased from approximately $5.4 million for the three months ended June 30, 2005 to approximately $10.2 million for the three months ended June 30, 2006, primarily due to new mortgage notes and mortgage notes assumed in connection with property acquisitions during the last six months of 2005, as well as an increase in average borrowings under our line of credit. Average borrowings under our line of credit increased from approximately $0.9 million during the three months ended June 30, 2005 to $163.4 million during the three months ended June 30, 2006. Future levels of interest expense will vary primarily based on the amounts of future

borrowings and the costs of borrowings. Future borrowings will be used primarily to fund future acquisitions of real estate or interests therein. Accordingly, the amounts of future borrowings and future interest expense will largely depend on the level of additional proceeds we raise in this offering and any future offerings, the opportunities to acquire real estate assets consistent with our investment objectives, and the timing of such future acquisitions.

Minority interest in earnings of consolidated entities increased from approximately $75,000 for the three months ended June 30, 2005 to approximately $405,000 for the three months ended June 30, 2006. This increase is primarily a result of acquiring interests in three separate joint ventures, as well as the consolidation of a variable interest entity in which we are the primary beneficiary, during the last six months of 2005. Earnings allocated to minority interest partners fluctuate based on the level of earnings generated by the respective properties and the nature of the allocation provisions provided in the joint venture agreements.

Net income and net income per share increased from approximately $1.4 million and $0.01, respectively, for the three months ended June 30, 2005 to approximately $4.1 million and $0.02, respectively, for the three months ended June 30, 2006, primarily due to the increase in net operating income generated from our growing portfolio of properties outpacing the increase in portfolio expenses during the three months ended June 30, 2006, as compared to the three months ended June 30, 2005. We expect future real estate acquisitions to result in an increase in net income in future periods. The level of future net income per share will vary primarily based on the level of proceeds raised in this offering and any future offerings and the rate at which we are able to invest such proceeds in income-generating real estate assets.

Comparison of the six months ended June 30, 2005 versus the six months ended June 30, 2006

Rental income and tenant reimbursements increased from approximately $54.9 million and $11.1 million, respectively, for the six months ended June 30, 2005 to approximately $114.8 million and $27.4 million, respectively, for the six months ended June 30, 2006, primarily as a result of the growth in the portfolio during the last six months of 2005 and the first six months of 2006. Rental income and tenant reimbursements are expected to continue to increase in future periods, as compared to historical periods, as a result of owning the assets acquired during the last six months of 2005 and the first six months of 2006 for an entire period and future acquisitions of real estate assets.

Hotel income and hotel operating costs of approximately $10.4 million and $8.0 million, respectively, were recognized for the six months ended June 30, 2006 and reflect earnings on one hotel property located in Cleveland, Ohio, which we acquired during the fourth quarter of 2005.

Property operating costs and asset and property management fees increased from approximately $18.1 million and $5.4 million, respectively, for the six months ended June 30, 2005 to approximately $43.0 million and $12.0 million, respectively, for the six months ended June 30, 2006, primarily as a result of the growth in the portfolio during the last six months of 2005 and the first six months of 2006. Property operating costs and asset and property management fees are expected to continue to increase in future periods, as compared to historical periods, due to owning the assets acquired during the last six months of 2005 and the first six months of 2006 for an entire period and future acquisitions of additional real estate assets.

Depreciation of real estate and amortization of related lease costs increased from approximately $9.2 million and $18.0 million, respectively, for the six months ended June 30, 2005 to approximately $21.9 million and $39.5 million, respectively, for the six months ended June 30, 2006, primarily due to the acquisition of properties during the last six months of 2005 and the first six months of 2006. We expect depreciation and amortization to continue to increase in future periods, as compared to historical periods, due to future acquisitions of real estate assets.

General and administrative expenses increased from approximately $4.6 million for the six months ended June 30, 2005 to approximately $5.9 million for the six months ended June 30, 2006, primarily due to increases in salary expense reimbursements payable to Wells Capital and Wells Management as a result of acquiring additional properties during the last six months of 2005 and the first six months of 2006. General and administrative expenses as a percent of total revenues decreased from approximately 7% for the six months ended June 30, 2005 to approximately 4% for the six months ended June 30, 2006.

Interest expense increased from approximately $11.2 million for the six months ended June 30, 2005 to approximately $21.3 million for the six months ended June 30, 2006, primarily due to new mortgage notes and mortgage notes assumed in connection with property acquisitions during the last six months of 2005, as well as an increase in average borrowings under our line of credit. Average borrowings under our line of credit increased from approximately $19.7 million during the first six months of 2005 to $217.3 million during the first six months of 2006. Future levels of interest expense will vary primarily based on the amounts of future borrowings and the costs of borrowings. Future borrowings will be used primarily to fund future acquisitions of real estate or interests therein. Accordingly, the amounts of future borrowings and future interest expense will largely depend on the level of additional proceeds we raise in this offering and any future offerings, the opportunities to acquire real estate assets consistent with our investment objectives, and the timing of such future acquisitions.

We recognized a loss on early extinguishment of debt of $1.1 million during the six months ended June 30, 2006 in connection with prepaying the University Circle Buildings mortgage note in January 2006. The loss resulted from a prepayment penalty of $5.7 million and a write-off of $0.6 million in deferred financing costs, partially offset by a write-off of the unamortized fair value adjustment to debt of approximately $5.2 million.

Minority interest in earnings of consolidated entities increased from approximately $106,000 for the six months ended June 30, 2005 to approximately $376,000 for the six months ended June 30, 2006. This increase is primarily a result of acquiring interests in three separate joint ventures, as well as the consolidation of a variable interest entity in which we are the primary beneficiary, during the last six months of 2005. Earnings allocated to minority interest partners fluctuate based on the level of earnings generated by the respective properties and the nature of the allocation provisions provided in the joint venture agreements.

Net income increased from approximately $2.2 million for the six months ended June 30, 2005 to approximately $3.2 million for the six months ended June 30, 2006, while net income per share decreased from approximately $0.02 for the six months ended June 30, 2005 to approximately $0.01 for the six months ended June 30, 2006. The increase in net income is primarily due to the increase in net operating income generated from our growing portfolio of properties outpacing the increase in portfolio expenses during the six months ended June 30, 2006, as compared to the six months ended June 30, 2005. The decrease in net income per share is primarily due to the increase in proceeds raised in this offering outpacing the increase in net income. We expect future real estate acquisitions to result in an increase in net income in future periods and expect future net income per share to fluctuate primarily based on the level of proceeds raised in this offering and any future offerings the rate at which we are able to invest such proceeds in income-generating real estate assets.

Funds From Operations

Funds from operations (“FFO”) is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income. We believe that FFO is a beneficial indicator of the performance of equity REITs. Specifically, FFO calculations exclude factors such as depreciation and amortization of real estate assets and gains or losses from sales of operating real estate assets. As such factors can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates, FFO may provide a valuable comparison of operating performance between periods and with other REITs. Management believes that accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered the presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. As a result, we believe that the use of FFO, together with the required GAAP presentation, provides a more complete understanding of our performance relative to our competitors and a more informed and appropriate basis on which to make decisions involving operating, financing, and investing activities. We calculate FFO in accordance with the current National Association of Real Estate Investment Trust (“NAREIT”) definition. However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do.

As presented below, FFO is adjusted to exclude the impact of certain noncash items, such as depreciation, amortization, and gains on the sale of real estate assets. Reconciliations of net income to FFO are presented below (in thousands):

Set forth below is additional information related to certain cash and noncash items included in or excluded from net income above, which may be helpful in assessing our operating results. In addition, cash flows generated from FFO may be used to fund all or a portion of certain capitalizable items that are excluded from FFO, such as capitalized interest, tenant improvements, building improvements, and deferred lease costs. See the accompanying consolidated statements of cash flows for detail of our operating, investing, and financing cash activities.

Noncash Items Included in Net Income:

Cash Item Excluded from Net Income:

Election as a REIT

We have elected to be taxed as a REIT under the Internal Revenue Code of 1986 (the “Code”), as amended, and have operated as such beginning with our taxable year ended December 31, 2003. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of our adjusted taxable income, as defined in the Code, to our stockholders, computed without regard to the dividends-paid deduction and by excluding our net capital gain. As a REIT, we generally will not be subject to federal income tax on income that we distribute to our stockholders. If we fail to qualify as a REIT in any taxable year, we will then be subject to federal income taxes on our taxable income for that year and for the four years following the year during which qualification is lost, unless the Internal Revenue Service grants us relief under certain statutory provisions. Such an event could materially adversely affect our net income and net cash available for distribution to our stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT for federal income tax purposes.

On October 4, 2005, we created Wells TRS II, LLC (“Wells TRS”), a wholly owned subsidiary organized as a Delaware limited liability company, which owns, among other things, an interest in a full-service hotel. We have elected to treat Wells TRS as a taxable REIT subsidiary. We may perform additional, non-customary services for tenants of buildings that we own through Wells TRS, including any real estate or non-real estate related services; however, any earnings related to such services are subject to federal and state income taxes. In addition, in order for us to continue to qualify as a REIT, our investments in taxable REIT subsidiaries cannot exceed 20% of the value of our total assets. Wells TRS had net operating income on an income tax basis for the three months ended June 30, 2006 and incurred a net operating loss on an income tax basis for the six months ended June 30, 2006. The related deferred tax asset as of June 30, 2006 and December 31, 2005 is included in prepaid and other assets in the accompanying consolidated balance sheets; the related expense for the three months ended June 30, 2006 and related benefit for the six months ended June 30, 2006 are included in the accompanying consolidated statements of income.

No provision for federal income taxes has been made in our accompanying consolidated financial statements, other than the provision relating to Wells TRS, as we made distributions in excess of taxable income for the periods presented. We are subject to certain state and local taxes related to property operations in certain locations, which have been provided for in our accompanying consolidated financial statements.

Inflation

We are exposed to inflation risk, as income from long-term leases is the primary source of our cash flows from operations. There are provisions in the majority of our tenant leases that are intended to protect us from, and mitigate the risk of, the impact of inflation. These provisions include rent steps, reimbursement billings for operating expense pass-through charges, real estate tax and insurance reimbursements on a per square-foot basis, or in some cases, annual reimbursement of operating expenses above a certain per square-foot allowance. However, due to the long-term nature of the leases, the leases may not re-set frequently enough to fully cover inflation.

Application of Critical Accounting Policies

Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied, thus resulting in a different presentation of the financial statements. Additionally, other companies may utilize different estimates that may impact comparability of our results of operations to those of companies in similar businesses.

Investment in Real Estate Assets

We are required to make subjective assessments as to the useful lives of our depreciable assets. We consider the period of future benefit of the asset to determine the appropriate useful lives. These assessments have a direct impact on net income. The estimated useful lives of our assets by class are as follows:

Allocation of Purchase Price of Acquired Assets

Upon the acquisition of real properties, we allocate the purchase price of properties to acquired tangible assets, consisting of land and building, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based in each case on our estimate of their fair values.

The fair values of the tangible assets of an acquired property (which includes land and building) are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and building based on our determination of the relative fair value of these assets. We determine the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors we consider in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases, including leasing commissions and other related costs. In estimating carrying costs, we include real estate taxes, insurance, and other operating expenses during the expected lease-up periods based on current market conditions.

The fair values of above-market and below-market in-place leases are recorded based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) our estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining terms of the leases. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental income over the remaining terms of the respective leases.

The fair values of in-place leases include direct costs associated with obtaining a new tenant, opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease, and tenant relationships. Direct costs associated with obtaining a new tenant include commissions, tenant improvements and other direct costs and are estimated based on our consideration of current market costs to execute a similar lease. These direct costs are included in deferred lease costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. Customer relationships are valued based on expected renewal of a lease or the likelihood of obtaining a particular tenant for other locations. These lease intangibles are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases.

Estimates of the fair values of the tangible and intangible assets require us to estimate market lease rates, property operating expenses, carrying costs during lease-up periods, discount rates, market absorption periods, and the number of years the property is held for investment. The use of inappropriate estimates would result in an incorrect assessment of our purchase price allocations, which would impact the amount of our reported net income.

Valuation of Real Estate Assets

We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate and related intangible assets of both operating properties and properties under construction, in which we have an ownership interest, either directly or through investments in joint ventures, may not be recoverable. When indicators of potential impairment are present that suggest that the carrying amounts of real estate and related

intangible assets may not be recoverable, we assess the recoverability of these assets by determining whether the carrying value will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we decrease the carrying value of the real estate and related intangible assets to the estimated fair values, as defined by Statement of Financial Accounting Standard No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, and recognize an impairment loss. Estimated fair values are calculated based on the following information, in order of preference, dependent upon availability: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of undiscounted cash flows, including estimated salvage value. We have determined that there has been no impairment in the carrying value of our real estate assets during the six months ended June 30, 2006 and 2005.

Projections of expected future operating cash flows require that we estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property and the number of years the property is held for investment, among other factors. The subjectivity of assumptions used in the future cash flow analysis, including discount rates, could result in an incorrect assessment of the property’s fair value and could result in the misstatement of the carrying value of our real estate and related intangible assets and net income.

Related-Party Transactions and Agreements

We have entered into agreements with our advisor, Wells Capital, and its affiliates, whereby we pay certain fees and reimbursements to Wells Capital or its affiliates, for acquisition fees, commissions, dealer-manager fees, asset and property management fees, construction fees, reimbursement of organizational and offering costs, and reimbursement of operating costs. See Note 7 to our accompanying consolidated financial statements included herein for a discussion of the various related-party transactions, agreements and fees.

Commitments and Contingencies

We are subject to certain commitments and contingencies with regard to certain transactions. Refer to Note 8 to our accompanying consolidated financial statements for further explanation. Examples of such commitments and contingencies include:

Events Subsequent to June 30, 2006

Subsequent to June 30, 2006, we sold additional shares of common stock as more fully explained in this supplement no. 2 under the heading “Status of Our Public Offerings.” On July 20, 2006, we acquired the 263 Shuman Boulevard Building as described under the heading “Acquisition of the 263 Shuman Boulevard Building.” On August 9, 2006, we acquired the 11950 Corporate Boulevard Building as described under the heading “Acquisition of the 11950 Corporate Boulevard Building.”

1. Organization

Wells Real Estate Investment Trust II, Inc. (“Wells REIT II”) is a Maryland corporation that has elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes. Wells REIT II engages in the acquisition and ownership of commercial real estate properties throughout the United States, including properties that are under construction, are newly constructed, or have operating histories. Wells REIT II was incorporated on July 3, 2003 and commenced operations on January 22, 2004. Wells REIT II conducts business primarily through Wells Operating Partnership II, L.P. (“Wells OP II”), a Delaware limited partnership. Wells REIT II is the sole general partner of Wells OP II and controls the operations of Wells OP II. Wells REIT II owns more than 99.9% of the equity interests in Wells OP II. Wells Capital, Inc. (“Wells Capital”), the external advisor to Wells REIT II, is the sole limited partner of Wells OP II. Wells OP II acquires, develops, owns, leases, and operates real properties directly, through wholly owned subsidiaries or through joint ventures. References to Wells REIT II herein shall include all subsidiaries of Wells REIT II, including consolidated joint ventures, Wells OP II, and Wells OP II’s subsidiaries. See Note 7 for a discussion of the advisory services provided by Wells Capital.

As of June 30, 2006, Wells REIT II owned interests in 40 office properties, one industrial building, and one hotel, comprising approximately 11.6 million square feet of rentable space located in 16 states and the District of Columbia. Thirty-six of the properties are wholly owned and six are owned through consolidated joint ventures. As of June 30, 2006, the office and industrial properties were approximately 96% leased.

On December 1, 2003, Wells REIT II commenced its initial public offering of up to 785.0 million shares of common stock, of which 185.0 million shares were reserved for issuance through Wells REIT II’s dividend reinvestment plan, pursuant to a Registration Statement filed on Form S-11 under the Securities Act of 1933. Except for continuing to offer shares for sale through its dividend reinvestment plan, Wells REIT II stopped offering shares for sale under its initial public offering on November 26, 2005. Wells REIT II raised gross offering proceeds of approximately $2.0 billion from the sale of approximately 197.1 million shares under its initial public offering, including shares sold under the dividend reinvestment plan after the primary offering had terminated. On November 10, 2005, Wells REIT II commenced a follow-on offering of up to 300.6 million shares of common stock, of which 0.6 million shares were reserved for issuance under Wells REIT II’s dividend reinvestment plan, pursuant to a Registration Statement filed on Form S-11 under the Securities Act of 1933. On April 14, 2006, Wells REIT II amended the aforementioned registration statements to offer in a combined prospectus the 300.6 million shares registered under the follow-on offering and 174.4 million unsold shares related to the dividend reinvestment plan and registered under the initial public offering. As of June 30, 2006, Wells REIT II had raised gross offering proceeds of approximately $443.2 million from the sale of approximately 44.3 million shares under the follow-on offering, including dividend reinvestment plan shares sold under the combined prospectus.

Wells REIT II has raised gross offering proceeds from the sale of common stock under the initial public offering and follow-on offering of approximately $2.4 billion. After deductions from such gross offering proceeds for payments of acquisition fees of approximately $48.1 million, selling commissions and dealer-manager fees of approximately $226.5 million, other organization and offering expenses of approximately $38.3 million, and common stock redemptions of approximately $31.3 million under the share redemption program, Wells REIT II had received aggregate net offering proceeds of approximately $2.1 billion as of June 30, 2006. Substantially all of Wells REIT II’s net offering proceeds have been invested in real properties.

Wells REIT II’s stock is not listed on a public securities exchange. However, Wells REIT II’s charter requires that, in the event that Wells REIT II’s stock is not listed on a national securities exchange by October 2015, Wells REIT II must either seek stockholder approval of an extension or amendment of this listing deadline or stockholder approval to begin liquidating investments and distributing the resulting proceeds to the stockholders. In the event that Wells REIT II seeks stockholder approval for an extension or amendment to this listing date and does not obtain it, Wells REIT II will then be required to seek stockholder approval to liquidate. In this circumstance, if Wells REIT II seeks and does not obtain approval to liquidate, Wells REIT II will not be required to list or liquidate and could continue to operate indefinitely as an unlisted company.

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements of Wells REIT II have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, including the instructions to Form 10-Q and Article 10 of Regulation S-X, and do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, the statements for these unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Results for these interim periods are not necessarily indicative of a full year’s results. Wells REIT II’s consolidated financial statements include the accounts of Wells REIT II, Wells OP II, and a variable interest entity in which Wells REIT II is the primary beneficiary. For further information, refer to the financial statements and footnotes included in Wells REIT II’s prospectus dated April 26, 2006.

Redeemable Common Stock

As of June 30, 2006, Wells REIT II’s share redemption program provided that all redemptions during any calendar year, including those upon death or qualifying disability, are limited to those that can be funded with proceeds raised in the current calendar year from Wells REIT II’s dividend reinvestment plan. As the use of those proceeds for redemptions is outside the control of Wells REIT II, those proceeds are considered to be temporary equity under Accounting Series Release No. 268, Presentation in Financial Statements of Redeemable Preferred Stock. Therefore, Wells REIT II has included an amount equal to proceeds from shares issued through Wells REIT II’s dividend reinvestment plan in the current calendar year, less the amount of redemptions previously funded with such proceeds, as redeemable common stock in the accompanying consolidated financial statements as of June 30, 2006.

Wells REIT II’s redeemable common shares are contingently redeemable at the option of the holder until such shares are tendered for redemption. Accordingly, pursuant to Statement of Financial Accounting Standard (“SFAS”) No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity (“SFAS 150”), Wells REIT II reclassifies such obligations from mezzanine equity to a liability based upon their respective settlement values upon being tendered for redemption. As of June 30, 2006 and December 31, 2005, shares tendered for redemption of approximately $36,000 and $0, respectively, have not been redeemed, and are, therefore, included in accounts payable, accrued expenses, and accrued capital expenditures in the accompanying consolidated balance sheets.

Revenue Recognition – Hotel Operations

Wells REIT II owns an interest in a full-service hotel. Revenues derived from the operations of the hotel include, but are not limited to, revenues from rental of rooms, food and beverage sales, telephone usage, and other service revenues. Revenue is recognized when rooms are occupied, when services have been performed, and when products are delivered.

Income Taxes

Wells REIT II has elected to be taxed as a REIT under the Internal Revenue Code of 1986 (the “Code”), as amended, and has operated as such beginning with its taxable year ended December 31, 2003. To qualify as a REIT, Wells REIT II must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its adjusted taxable income, as defined in the Code, to its stockholders. As a REIT, Wells REIT II generally is not subject to income tax on income it distributes to stockholders. Wells REIT II is subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in the accompanying consolidated financial statements.

On October 4, 2005, Wells REIT II created Wells TRS II, LLC (“Wells TRS”), a wholly owned subsidiary organized as a Delaware limited liability company, which owns, among other things, an interest in a full-service hotel. Wells REIT II has elected to treat Wells TRS as a taxable REIT subsidiary. Wells REIT II may perform additional, non-customary services for tenants of buildings owned by Wells REIT II through Wells TRS, including any real estate or non-real estate related services; however, any earnings related to such services are subject to federal and state income taxes. In addition, for Wells REIT II to continue to qualify as a REIT, Wells REIT II’s

F-7

investments in taxable REIT subsidiaries cannot exceed 20% of the value of the total assets of Wells REIT II. Deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted rates expected to be in effect when the temporary differences reverse. Wells TRS had net operating income on an income tax basis for the three months ended June 30, 2006 and incurred a net operating loss on an income tax basis for the six months ended June 30, 2006. The related deferred tax asset as of June 30, 2006 and December 31, 2005 is included in prepaid and other assets in the accompanying consolidated balance sheets; the related expense for the three months ended June 30, 2006 and the related benefit for the six months ended June 30, 2006 are included in the accompanying consolidated statements of income.

Recent Accounting Pronouncement

In July 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109, (“FIN 48”), which clarifies the relevant criteria and approach for the recognition, derecognition, and measurement of uncertain tax positions. FIN 48 will be effective for Wells REIT II beginning January 1, 2007. Wells REIT II is currently in the process of assessing the provisions of FIN 48; however, Wells REIT II does not expect the adoption of this interpretation to have a material impact on its consolidated financial statements.

Reclassifications

Certain prior period amounts have been reclassified to conform with the current period financial statement presentation.

3. Real Estate Acquisition

Summary

As of June 30, 2006, Wells REIT II owned interests in 42 properties as a result of acquiring 18 properties during the year ended December 31, 2004, acquiring 21 properties during the year ended December 31, 2005, and acquiring 2 properties and completing construction of the LakePointe 3 building during the second quarter of 2006.

SanTan Buildings Acquisition

On April 18, 2006, Wells REIT II purchased two, three-story office buildings containing approximately 268,000 aggregate rentable square feet located on an approximate 16.4-acre tract of land at 3100-3200 West Ray Road in Chandler, Arizona (the “SanTan Buildings”) for a purchase price of approximately $59.3 million, exclusive of closing costs and adjustments. The SanTan Buildings, which were constructed in 2000 and 2003, are leased to Toyota Motor Credit Corporation (approximately 50%), ISOLA USA Corporation (approximately 9%), and various other office tenants (approximately 41%).

4. Line of Credit and Notes Payable

As of June 30, 2006 and December 31, 2005, Wells REIT II had the following indebtedness outstanding (in thousands):

During the three months ended June 30, 2006, Wells REIT II engaged in the following significant activities with respect to its line of credit and notes payable:

The line of credit represents a $400.0 million unsecured revolving financing facility (the “Wachovia Line of Credit”) with a syndicate of banks led by Wachovia Bank, N.A., which expires May 9, 2008. During 2005, Wells REIT II pledged approximately $9.2 million of its borrowing capacity under the Wachovia Line of Credit to letters of credit for future tenant improvements and leasing costs. As of June 30, 2006, after consideration of the letters of credit, Wells REIT II had a remaining borrowing capacity of up to approximately $306.8 million under the Wachovia Line of Credit. During the three months ended June 30, 2006, Wells REIT II made net repayments of $111.0 million on the Wachovia Line of Credit.

The LakePointe 3 construction loan is a debt instrument used to fund a portion of the costs necessary to build an office building in Charlotte, North Carolina, which was completed in May 2006. The loan matures in 2007 and requires monthly interest payments at a rate of monthly LIBOR, plus 100 basis points (approximately 6.1% per annum as of June 30, 2006). During the fourth quarter of 2005, Wells REIT II entered into an interest rate swap agreement to hedge exposure to changing interest rates. Under the terms of the interest rate swap agreement, Wells REIT II is obligated to pay a monthly interest payment at a fixed rate of 4.84% per annum of the lesser of the outstanding balance on the construction loan or the notional amount under the swap agreement. The interest rate swap expires in 2007.

Wells REIT II made interest payments, including amounts capitalized, of approximately $19.1 million and $7.8 million during the six months ended June 30, 2006 and 2005, respectively. This excludes the $5.7 million prepayment penalty paid in January 2006 related to the University Circle Buildings mortgage note which is included in loss on early extinguishment of debt in the accompanying consolidated statements of income.

5. Share Redemption Program

The board of directors of Wells REIT II has approved an amendment to the share redemption program (“SRP”), which will become effective September 9, 2006. The amendment grants Wells REIT II discretion to redeem all shares submitted for redemption upon the death of stockholders. The redemption limits set forth in the SRP are summarized below:

F-9

Although there is no limit on the number of shares Wells REIT II may redeem upon the death of stockholders, Wells REIT II is under no obligation to redeem such shares to the extent such redemptions would cause total redemptions to exceed the two limits set forth immediately above.

6. Supplemental Disclosures of Noncash Activities

Outlined below are significant noncash investing and financing transactions for the six months ended June 30, 2006 and 2005 (in thousands):

7. Related-Party Transactions

Advisory Agreement

On October 20, 2005, Wells REIT II entered into a new advisory agreement (the “Advisory Agreement”) with Wells Capital, which entitles Wells Capital to earn specified fees for certain services. The Advisory Agreement is effective through October 19, 2006; however, either party may terminate the Advisory Agreement without cause or penalty upon providing 60 days’ written notice. If initiating termination of the Advisory Agreement, Wells REIT II would be obligated to pay all unpaid earned fees and reimbursements of expenses to Wells Capital.

Under the terms of the Advisory Agreement, Wells Capital receives the following fees and reimbursements:

Due to Affiliates

The detail of amounts due to affiliates is provided below as of June 30, 2006 and December 31, 2005 (in thousands):

Economic Dependency

Wells REIT II has engaged Wells Capital and its affiliates, Wells Management and WIS, to provide certain services that are essential to Wells REIT II, including asset management services, supervision of the management and leasing of some properties owned by Wells REIT II, asset acquisition and disposition services, the sale of shares of Wells REIT II’s common stock, as well as other administrative responsibilities for Wells REIT II including accounting services, stockholder communications, and investor relations. These agreements are terminable by either party upon 60 days’ written notice. As a result of these relationships, Wells REIT II is dependent upon Wells Capital, Wells Management, and WIS.

Wells Capital, Wells Management, and WIS are all owned and controlled by Wells Real Estate Funds, Inc. (“WREF”). The operations of Wells Capital, Wells Management, and WIS represent substantially all of the business of WREF. Accordingly, Wells REIT II focuses on the financial condition of WREF when assessing the financial condition of Wells Capital, Wells Management, and WIS. In the event that WREF was to become unable to meet its obligations as they become due, Wells REIT II might be required to find alternative service providers.

Future net income generated by WREF will be largely dependent upon the amount of fees earned by Wells Capital and Wells Management based on, among other things, the level of investor proceeds raised from the sale of Wells REIT II’s common stock and the volume of future acquisitions and dispositions of real estate assets by WREF-sponsored programs. As of June 30, 2006, Wells REIT II believes that WREF is generating adequate cash flow from operations and has adequate liquidity available in the form of cash on hand and current receivables necessary to meet its current and future obligations as they become due.

8. Commitments and Contingencies

Take-Out Agreements

Wells Management has developed a program that involves the acquisition of income-producing commercial properties through a series of single-member limited liability companies for the purpose of facilitating the resale of co-tenancy interests in such real estate properties (the “Wells Section 1031 Program”) to persons seeking to reinvest the proceeds from a sale of real estate held for investment in another real estate investment in order to qualify for like-kind exchange treatment under Section 1031 of the Internal Revenue Code (“1031 Participants”). Acquisitions of properties for the Wells Section 1031 Program are generally financed with a combination of permanent first mortgage financing and interim financing obtained from institutional lenders. Following the acquisition of a property, a subsidiary of Wells Management attempts to sell co-tenancy interests in such property to 1031 Participants. The proceeds from such sales are typically used to immediately repay the interim financing.

As of June 30, 2006, Wells REIT II had commitments outstanding under three Take-Out Purchase and Escrow Agreements (the “Take-Out Agreements”). Under the terms of the Take-Out Agreements, Wells REIT II receives a fee in exchange for committing to purchase any of the co-tenancy interests described above that remain unsold to 1031 Participants on the maturity date of the interim financing obtained to acquire the properties. In consideration
