CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this Form 10-Q of Wells Real Estate Fund XII, L.P. (the Partnership) other than historical facts may be
considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Such statements include, in particular, statements about our plans, strategies,
and prospects and are subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a
guarantee of our performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as may, will, expect, intend,
anticipate, estimate, believe, continue, or other similar words. Specifically, we consider, among others, statements concerning future operating results and cash flows, our ability to meet future
obligations, and the amount and timing of any future distributions to limited partners to be forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date this
report is filed with the Securities and Exchange Commission. We make no representations or warranties (express or implied) about the accuracy of any such forward-looking statements contained in this Form 10-Q, and we do not intend to publicly update
or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Any such forward-looking
statements are subject to unknown risks, uncertainties, and other factors and are based on a number of assumptions involving judgments with respect to, among other things, future economic, competitive, and market conditions, all of which are
difficult or impossible to predict accurately. To the extent that our assumptions differ from actual results, our ability to meet such forward-looking statements, including our ability to generate positive cash flow from operations, provide
distributions to partners, and maintain the value of our real estate properties, may be significantly hindered. See Item 1A in the Partnerships Annual Report on Form 10-K for the year ended December 31, 2005 for a discussion of some
of the risks and uncertainties, although not all risks and uncertainties, which could cause actual results to differ materially from those presented in our forward-looking statements.

|2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------

Basis of Presentation

The financial statements of the Partnership 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 in accordance with such rules and regulations, 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 the General Partners, the statements for the unaudited interim periods presented include all adjustments that are of a normal and
recurring nature and necessary to fairly and consistently present the results for these periods. Results for interim periods are not necessarily indicative of full-year results. For further information, refer to the financial statements and
footnotes included in the Partnerships Annual Report on Form 10-K for the year ended December 31, 2005.

Investment in Joint Ventures

The Partnership has evaluated the Joint Ventures and concluded that none are variable interest entities under the provisions of
Financial Accounting Standards Board Interpretation No. (FIN) 46(R), Consolidation of Variable Interest Entities, which supersedes FIN 46 and is an interpretation of Accounting Research Bulletin (ARB) No. 51,
Consolidated Financial Statements. The Partnership does not have control over the operations of the Joint Ventures; however, it does exercise significant influence. Approval by the Partnership as well as the other joint venture partners is
required for any major decision or any action that would materially affect the Joint Ventures, or their real property investments. Accordingly, upon applying the provisions of Statement of Financial Accounting Standard (SFAS)
No. 94, Consolidation of All Majority-Owned Subsidiaries, ARB No. 51, and

capital contributions, as defined.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Second, to the General Partners until the General Partners receive distributions equal to 10% of the total cumulative distributions paid by the Partnership to

Upon the sale of

| |  |  | In the event that the particular property sold is sold for a price that is less than the original property purchase price, to the limited partners holding Cash
Preferred Units until they have received an amount equal to the excess of the original property purchase price over the price for which the property was sold, limited to the amount of depreciation, amortization, and cost recovery deductions taken by
the limited partners holding Tax Preferred Units with respect to such property;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To limited partners holding units which at any time have been treated as Tax Preferred Units until each limited partner has received an amount necessary to equal
the net cash available for distribution received by the limited partners holding Cash Preferred Units on a per-unit basis;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To limited partners on a per-unit basis until each limited partner has received 100% of his net capital contributions, as defined;

a 10% per annum cumulative return on net capital contributions for all periods during which the units were treated as Cash Preferred Units and a 15% per annum cumulative return on net capital contributions for all periods during which the
units were treated as Tax Preferred Units);
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To the General Partners until they have received 100% of their capital contributions, as defined;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | Then, if limited partners have received any excess limited partner distributions (defined as distributions to limited partners over the life of their investment
in the Partnership in excess of their net capital contributions, as defined, plus their preferential limited partner return), to the General Partners until they have received distributions equal to 20% of the sum of any such excess limited partner
distributions plus distributions made to the General Partners pursuant to this provision; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Allocations of Net Income, Net Loss, and Gain on Sale

For the purpose of determining allocations per the partnership agreement, net income is defined as net income recognized by the Partnership, excluding deductions for depreciation, amortization,
and cost recovery and the gain on the sale of assets. Net income, as defined, of the Partnership is generally allocated each year in the same proportion that net cash from operations is distributed to the partners holding Cash Preferred Units and
the General Partners. To the extent the Partnerships net income in any year exceeds net cash from operations, it will be allocated 99% to the limited partners holding Cash Preferred Units and 1% to the General Partners.

Net loss, depreciation, amortization, and cost recovery deductions for each fiscal year will be allocated as follows: (a) 99% to the limited
partners holding Tax Preferred Units and 1% to the General Partners until their capital accounts are reduced to zero; (b) then, to any partner having a positive balance in his capital account in an amount not to exceed such positive balance;
and (c) thereafter, to the General Partners.

Gains on the sale or exchange of the Partnerships properties will be allocated
generally in the same manner that the net proceeds from such sale are distributed to partners after the following allocations are made, if applicable: (a) allocations made pursuant to the qualified income offset provisions of the partnership
agreement; (b) allocations to partners having negative capital accounts until all negative capital accounts have been restored to zero; and (c) allocations to limited partners holding Tax Preferred Units in amounts equal to the deductions
for depreciation, amortization, and cost recovery previously allocated to them with respect to the specific partnership property sold, but not in excess of the amount of gain on sale recognized by the Partnership with respect to the sale of such
property.

Due from Joint Ventures

As presented in the accompanying balance sheets, due from joint ventures as of June 30, 2006 and December 31, 2005 represents operating cash flow generated by the Joint Ventures for the three months ended
June 30, 2006 and December 31, 2005, respectively, which is attributable to the Partnership.



|4. | RELATED-PARTY TRANSACTIONS
|-- | --------------------------

Management
and Leasing Fees

Wells Management Company, Inc. (Wells Management), an affiliate of the General Partners, receives
compensation for the management and leasing of the Partnerships properties owned through the Joint Ventures equal to the lesser of (a) of the gross revenues collected monthly, 2.5% for management services and 2% for leasing services, plus
a separate competitive fee for the one-time initial lease-up of newly constructed properties in an amount not to exceed the fee customarily charged in arms-length transactions by others rendering similar services in the same geographic area
for similar properties or (b) in the case of commercial properties leased on a long-term net basis (ten or more years), the maximum property management fee from such leases shall be 1% of the gross revenues generally paid over the life of the
leases except for a one-time initial leasing fee of 3% of the gross revenues on each lease payable over the first five full years of the original lease term. Management and leasing fees are paid by the Joint Ventures and, accordingly, included in
equity in income of joint ventures in the accompanying statements of operations. The Partnerships share of management and leasing fees and lease acquisition costs incurred through the Joint Ventures is $15,909 and $17,414 for the three months
ended June 30, 2006 and 2005, respectively, and $36,388 and $58,212 for the six months ended June 30, 2006 and 2005, respectively.

Administration Reimbursements

Wells Capital, the corporate general partner of Wells Partners, one of our General Partners,
and Wells Management perform certain administrative services for the Partnership, relating to accounting, property management, and other partnership administration, and incur the related expenses. Such expenses are allocated among other entities
affiliated with the General Partners based on time spent on each fund by individual administrative personnel. In the opinion of the General Partners, this allocation is a reasonable estimation of such expenses. The Partnership reimbursed Wells
Capital and Wells Management for administrative expenses of $15,821 and $21,565 for the three months ended June 30, 2006 and 2005, respectively, and $32,625 and $43,365 for the six months ended June 30, 2006 and 2005, respectively. In
addition, Wells Capital pays for certain operating expenses of the Partnership (bill-backs) directly and invoices the Partnership for the reimbursement thereof. As of June 30, 2006 and December 31, 2005, the due to affiliates
balances represent administrative reimbursements and bill-backs due to Wells Management and/or Wells Capital.

##### Table of Contents

Economic Dependency

We have engaged Wells Capital and Wells Management to provide certain essential services, including supervision of the management and leasing of our properties, asset acquisition and disposition services, as well as
other administrative responsibilities for us including accounting services and investor communications and relations. These agreements are terminable by either party upon 60 days written notice. As a result of these relationships, we are
dependent upon Wells Capital and Wells Management.

Wells Capital and Wells Management are all owned and controlled by Wells Real Estate
Funds, Inc. (WREF). The operations of Wells Capital and Wells Management represent substantially all of the business of WREF. Accordingly, we focus on the financial condition of WREF when assessing the financial condition of Wells
Capital and Wells Management. In the event that WREF was to become unable to meet its obligations as they become due, we 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 common stock for certain WREF-sponsored programs and the volume of future acquisitions and dispositions of real estate assets by WREF-sponsored programs. As of June 30, 2006, the General Partners believe that WREF
generates 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.



|5. | COMMITMENTS AND CONTINGENCIES
|-- | -----------------------------

The Partnership and its General Partners are from time to time a party to legal proceedings, which arise in the ordinary course of its business. The Partnership is not currently involved in any legal proceedings of which the outcome is
reasonable likely to have a material adverse effect on results of operations or financial condition. The Partnership is not aware of any legal proceedings contemplated by governmental authorities.



|ITEM 2. | 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 financial statements and notes thereto. See also Cautionary Note Regarding Forward-Looking
Statements preceding Part I, as well as the notes to our financial statements and Managements Discussion and Analysis of Financial Condition and Results of Operations provided in our Annual Report on Form 10-K for the year ended
December 31, 2005.

Overview

The
Partnership typically operates in the following five life cycle phases and, during which, typically focuses on the following key operating objectives. The duration of each phase is dependent upon various economic, industry, market, and other
internal/external factors. Some overlap naturally exists in the transition from one phase to the next.



| |  |  | Fundraising phase
| | - |  | -----------------

The period during which the Partnership is raising capital through the sale and issuance of limited partner units to the public;



| |  |  | Investing phase
| | - |  | ---------------

The period during which the Partnership invests the capital raised during the fundraising phase, less upfront fees, into the acquisition of real estate assets;



| |  |  | Holding phase
| | - |  | -------------

The period during which the Partnership owns and operates its real estate assets during the initial lease terms of the tenants;



Page 14



---

##### Table of Contents

| |  |  | Positioning-for-sale phase
| | - |  | --------------------------

The period during which the leases in place at the time of acquisition expire and, thus, the Partnership expends time, effort, and funds to re-lease such space to existing and/or new tenants. Following the holding
phase, the Partnership continues to own and operate the real estate assets, evaluate various options for disposition, and market the real estate assets for sale; and



| |  |  | Disposition-and-liquidation phase
| | - |  | ---------------------------------

The period during which the Partnership sells its real estate investments, distributes net sale proceeds to the partners, liquidates, and terminates the Partnership.

Portfolio Overview

We are currently operating in the
holding phase of our life cycle. We currently own interests in four properties, following the sale of the Gartner Building and the AT&T Oklahoma Building in April 2005. Two of the buildings in which we currently own interests are 100% leased to
tenants in the early to middle stages of their lease terms, and the other two buildings are vacant. Our focus at this time involves leasing the two vacant properties and maximizing the operating performance of the remaining assets in order to
deliver what we believe will be the best overall performance for our limited partners.

While the forgoing property sales have delivered
positive results, we are also facing some near-term leasing issues with regard to the two vacant properties. These leasing challenges may impact future operating performance; however, we are aggressively working with prospective tenants in the
respective markets in an attempt to minimize negative financial effects.

Operating distributions payable to the Cash Preferred limited
partners for the second quarter of 2006 remained consistent with the level paid in the prior quarter. The General Partners anticipate that operating distributions will decline in the near-term, as we fund our pro-rata share of anticipated capital
improvements and re-leasing costs for the 20/20 Building and 111 Southchase Boulevard.

Property Summary

As we continue to operate in the holding phase, we will continue to focus on re-leasing vacant space and space that may become vacant upon the expiration
of our current leases. In doing so, we will seek to maximize returns to the limited partners by negotiating long-term leases at market rental rates while attempting to minimize down time, re-leasing expenditures, ongoing property level costs and
portfolio costs. Later as we move into the positioning-for-sale and disposition-and-liquidation phases, our attention will shift to locating suitable buyers and negotiating purchase-sale contracts that will attempt to maximize the total return to
the limited partners, and to minimize contingencies and our post-closing involvement with the buyer.

Liquidity and Capital Resources

Overview

Our operating strategy entails funding expenditures related to the recurring operations of
the Joint Ventures properties and the portfolio with operating cash flows, including current and prior period operating distributions received from the Joint Ventures, and assessing the amount of remaining cash flows that will be required to
fund known future re-leasing costs and other capital improvements. Any residual operating cash flows are generally considered available for distribution to the Cash Preferred limited partners and, unless reserved, are generally paid quarterly. As a
result, the ongoing monitoring of our cash position is critical to ensuring that adequate liquidity and capital resources are available. Economic downturns in one or more of our core markets could adversely impact the ability of our tenants to honor
lease payments and our ability to re-lease space on favorable terms as leases expire or space otherwise becomes vacant. In the event of either situation, cash flows and, consequently, our ability to provide funding for capital needs could be
adversely affected.

Short-Term Liquidity

During the six months ended June 30, 2006, we generated net operating cash flows, including operating distributions received from the Joint Ventures, of approximately $637,000, as compared to approximately $1,053,000 for the six months
ended June 30, 2005. The 2006 decline is primarily due to a decline in operating distributions received from the Joint Ventures as a result of the sales of the Gartner Building and the AT&T Oklahoma Building in April 2005. Distributions
from the Joint Ventures are generally representative of rental revenues and tenant reimbursements, less property operating expenses, management fees, general administrative expenses, and capital expenditures.

Future operating distributions from the Joint Ventures are expected to decline in the near-term as a result of funding our pro-rata share of anticipated
capital improvements and re-leasing costs for the 20/20 Building and 111 Southchase Boulevard, both of which are currently vacant. Future operating distributions paid to limited partners will be largely dependent upon the amount of cash generated
from the Joint Ventures, our expectations of future cash flows, and determination of near-term cash needs for tenant re-leasing costs and other capital improvements for properties owned by the Joint Ventures.

We believe that the cash on hand and operating distributions due from the Joint Ventures are sufficient to cover our working capital needs, including
liabilities of approximately $341,000, as of June 30, 2006. We anticipate using operating cash flow to fund our proportionate share of capital expenditures noted above over the next twelve months.

Long-Term Liquidity

We expect that our future
sources of capital will be primarily derived from operating cash flows generated from the Joint Ventures and net proceeds generated from the selective and strategic sale of properties. Our future long-term liquidity requirements will include, but
not be limited to, funding tenant improvements, renovations, expansions and other significant capital improvements necessary for properties owned through the Joint Ventures. We expect to continue to use substantially all future net cash flows from
operations, including distributions received from the Joint Ventures, less, expenses related to the recurring operations of the properties and the portfolio and reserves for known capital expenditures, to pay operating distributions to the limited
partners.

Capital Resources

The
Partnership is an investment vehicle formed for the purpose of acquiring, owning, and operating income-producing real properties and has invested all of the partners original capital contributions. Thus, it is unlikely that we will acquire
interests in any additional properties. Historically, our investment strategy has generally involved acquiring properties that are pre-leased to creditworthy tenants on an all-cash basis through joint ventures with affiliated partnerships.

##### Table of Contents

The Joint Ventures fund capital expenditures primarily related to building improvements for the purpose
of maintaining the quality of our properties, and tenant improvements for the purpose of readying our properties for re-leasing. As leases expire, we typically attempt to re-lease space to an existing tenant or market the space to prospective new
tenants. Generally, tenant improvements funded in connection with lease renewals require less capital than those funded in connection with new leases. However, external conditions, such as the supply of and demand for comparable space available
within a given market, drive capital costs as well as rental rates.

Operating cash flows, if available, are generally distributed from the
Joint Ventures to the Partnership approximately one month following quarter-ends. However, the Joint Ventures will reserve operating distributions, or a portion thereof, as needed in order to fund known capital and other expenditures. Our cash
management policy typically includes first utilizing current period operating cash flow until depleted, at which point operating reserves are utilized to fund capital and other required expenditures. In the event that current and prior period
accumulated operating cash flows are insufficient to fund such costs, net property sale proceeds reserves, if available, would then be utilized. Any capital or other expenditures not provided for by the operations of the Joint Ventures will be
required to be funded by the Partnership and the respective joint venture partners on a pro-rata basis.

As June 30, 2006, we have
received, used, distributed, and held net sale proceeds allocated to the Partnership from the sale of properties as presented below:

Results of Operations

Equity in Income of Joint Ventures

Equity in income of the Joint Ventures was $249,701 and $4,323,399 for the three months
ended June 30, 2006 and 2005, respectively, and $508,525 and $4,769,272 for the six months ended June 30, 2006 and 2005, respectively. The decreases in equity in income of the Joint Ventures for 2006, as compared to 2005, are primarily
attributable to (i) the gain recognized on the sales of the Gartner Building and the AT&T Oklahoma Building in April 2005, and (ii) a decline in operating income resulting from the sales of the Gartner Building and the AT&T
Oklahoma Building in April 2005.

We expect equity in income of the Joint Ventures to remain at similar levels going forward until the
vacant space at 111 Southchase Boulevard and the 20/20 Building is re-leased.

Expenses

Total expenses of the Partnership were $58,649 and $61,704 for the three months ended June 30, 2006 and 2005, respectively. The decrease for the three months ended June 30, 2006, as
compared to the three months ended June 30, 2005, is primarily attributable to a decline in administrative costs and accounting and legal fees as a result of nonrecurring costs relating to the sales of the Gartner Building and the AT&T
Oklahoma Building in the second quarter of 2005.

##### Table of Contents

Total expenses of the Partnership were $152,808 and $123,281 for the six months ended June 30, 2006
and 2005, respectively. The increase for the six months ended June 30, 2006, as compared to the six months ended June 30, 2005, is primarily a result of an adjustment to 2005 estimated Tennessee partnership franchise and excise taxes
incurred in the first quarter of 2006. We estimate Tennessee partnership franchise and excise taxes based on an estimate of the apportionment of income allocable to the Partnership from properties in Tennessee relative to income allocable to the
Partnership from all properties as if earned ratably during the calendar year. Thus, our future estimates of Tennessee partnership franchise and excise tax expenses will fluctuate as the relationship of income earned by the Partnership from
properties in Tennessee fluctuates relative to income earned by the Partnership from all properties in the future. Accordingly, nonrecurring items, such as gains on the sales of properties, will have a significant impact on these estimates.

We also anticipate additional increases in administrative expenses in future periods resulting from increased costs relating to compliance
with reporting and regulatory requirements.

Interest and Other Income

Interest and other income was $2,526 and $17,637 for the three months ended June 30, 2006 and 2005, respectively, and $8,901 and $25,047 for the six months ended June 30, 2006 and 2005, respectively. The
2006 decreases, as compared to 2005, are primarily a result of a decrease in the average amount of net sale proceeds held during 2006, primarily as a result of the distribution of net proceeds in May 2005 and November 2005.

Future levels of interest income will be largely dependent upon the timing of future dispositions and net sale proceeds distributions to the investors.

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 would protect us from 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 our leases, the leases may not readjust their reimbursement rates frequently enough to cover inflation.

Application of Critical Accounting Policies

Summary

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 managements 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.

Below is a discussion of the accounting policies used by the Partnership and the Joint Ventures, which are considered to be critical in that they may
require complex judgment in their application or require estimates about matters that are inherently uncertain.

Investment in Real Estate Assets

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



|                      |  |                                       
|--------------------- |  | --------------------------------------
|Buildings             |  | 40 years                              
|Building improvements |  | 5-25 years                            
|Land improvements     |  | 20 years                              
|Tenant improvements   |  | Shorter of lease term or economic life

In the event that the Joint Ventures utilize inappropriate useful lives or methods of
depreciation, our net income would be misstated.

Valuation of Real Estate Assets

We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate assets in which we have an ownership interest through investments in
the Joint Ventures may not be recoverable. When indicators of potential impairment are present which indicate that the carrying amounts of real estate assets may not be recoverable, management assesses the recoverability of the real estate assets by
determining whether the carrying value of the real estate assets will be recovered through the undiscounted future operating cash flows expected from the use of the assets and their eventual disposition. In the event that such expected undiscounted
future cash flows do not exceed the carrying value, management adjusts the real estate assets to the fair value, as defined by SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, and recognizes an impairment
loss. Estimated fair values are calculated based on the following information, dependent upon availability, in order of preference: (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 any of the real estate assets held by the Partnership as of June 30, 2006.

Projections of expected future cash flows require management to estimate future market rental income amounts subsequent to the expiration of current
lease agreements, property operating expenses, discount rates, the number of months it takes to re-lease the property, and the number of years the property is held for investment. The use of inappropriate assumptions in the future cash flow analysis
would result in an incorrect assessment of the propertys future cash flows and fair value, and could result in the overstatement of the carrying value of any of the real estate assets held by the Joint Ventures and net income of the
Partnership.

Related-Party Transactions and Agreements

We have entered into agreements with Wells Capital and Wells Management, affiliates of our General Partners, and their affiliates, whereby we pay certain fees and expense reimbursements to Wells Capital, Wells
Management and their affiliates for asset management; the management and leasing of our properties; administrative services relating to accounting, property management, and other partnership administration; and incur the related expenses. See Note 4
to our financial statements included in this report for a description of these fees and expense reimbursements we have incurred.

Potential Tax Impact
on Limited Partners Holding Tax Preferred Units  American Jobs Creation Act of 2004

The American Jobs Creation Act of 2004 added
Section 470 to the Internal Revenue Code, which provides for certain limitations on the utilization of losses by investors that are attributable to leased property owned by a partnership having both taxable and tax-exempt partners such as the
Partnership. If Section 470 were deemed to apply to the Partnership, passive losses allocable to limited partners holding Tax Preferred Units could only be

##### Table of Contents

utilized to offset passive income generated from the same property or potentially from properties owned by the same partnership. In March 2005, the Internal
Revenue Service (IRS) announced that the IRS would not apply Section 470 to partnerships for the taxable year 2004 based solely on the fact that a partnership had both taxable and tax-exempt partners, and in December 2005, the IRS
extended the period for transitional relief through the 2005 tax year. In addition, pursuant to Section 403(ff) of the Gulf Opportunity Zone Act of 2005, the effective date provisions regarding the applicability of Section 470 were amended
to provide that, in the case of leased property treated as tax-exempt use property by reason of its being owned by a partnership having both taxable and tax-exempt partners, Section 470 will apply only to property acquired after March 12,
2004. Since the Partnership acquired all of its properties prior to March 12, 2004, and is not expected to acquire interests in any additional properties in the future, we do not believe that the provisions of Section 470 should apply to
limit the utilization of losses attributable to the properties owned by the Partnership; however, due to the uncertainties and lack of guidance relating to this provision, it is unclear as to whether the acquisition of a limited partnership interest
in the Partnership after the March 12, 2004 effective date may be deemed to be an acquisition of property within the meaning of the effective date provisions of Section 470.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Since we do not borrow any money, make any foreign investments, or invest in any market risk-sensitive instruments, we are not subject to risks relating to interest rates, foreign current exchange rate fluctuations, or the other market
risks contemplated by Item 305 of Regulation S-K.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

We carried out an
evaluation, under the supervision and with the participation of management of Wells Capital, our corporate General Partner, including the Principal Executive Officer and the Principal Financial Officer of Wells Capital, of the effectiveness of the
design and operation of the Partnerships disclosure controls and procedures as defined in rule 13a-15(e) of the Securities Exchange Act of 1934 as of the end of the period covered by this report. Based upon that evaluation, the Principal
Executive Officer and the Principal Financial Officer of Wells Capital concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report in providing a reasonable level of assurance
that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in applicable SEC rules and forms, including
providing a reasonable level of assurance that information required to be disclosed by us in such reports is accumulated and communicated to our management, including the Principal Executive Officer and the Principal Financial Officer of Wells
Capital, as appropriate, to allow timely decisions regarding required disclosure.

There were no significant changes in our internal
control over financial reporting during the quarter ended June 30, 2006 that have materially affected, or are likely to materially affect, our internal control over financial reporting.
