CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this Form 10-Q of Wells Real Estate Fund XII, L.P. (the Partnership or the Registrant) 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, 2007 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 (SEC), 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, 2007.

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 (FIN) No. 46(R), Consolidation of Variable Interest Entities, which supersedes FIN No. 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 Statement of Position (SOP) No. 78-9, Accounting for Investments In Real Estate Ventures, the Partnership accounts for its investments in the Joint Ventures using the
equity method of accounting, whereby original investments are recorded at cost and subsequently adjusted for contributions, distributions, and net income (loss) attributable to the Partnership. Pursuant to the terms of the joint venture agreements,
all income (loss) and distributions are allocated to joint venture partners in accordance with their respective ownership interests. Distributions of net cash from operations, if available, are generally distributed to the joint venture partners on
a quarterly basis.

Distributions of Net Cash from Operations

Net cash from operations, if available, is generally distributed quarterly to the limited partners as follows:



| |  |  | First, to all Cash Preferred limited partners on a per-unit basis until each limited partner has received distributions equal to a 10% per annum return on his
respective net 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 date.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Third, to the Cash Preferred limited partners on a per-unit basis and the General Partners allocated on a basis of 90% and 10%, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

No distributions of net cash from operations will be made to limited partners holding Tax Preferred Units.

Distribution of Sale Proceeds

Upon the sale of properties, unless
reserved, net sale proceeds will be distributed in the following order:



| |  |  | 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 previously 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;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | To all limited partners on a per-unit basis until each limited partner has received a cumulative 10% per annum return on his net capital contributions, as
defined;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To limited partners on a per-unit basis until each limited partner has received an amount equal to his preferential limited partner return (defined as the sum of 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
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Thereafter, 80% to the limited partners on a per-unit basis and 20% to the General Partners.

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, 2008 and December 31, 2007 represents operating cash flow generated by the Joint Ventures for the three months ended
June 30, 2008 and December 31, 2007, respectively, which is attributable to the Partnership.



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

Management and Leasing Fees

In accordance with the property management and leasing agreement, 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) 2.5% for management services and 2% for leasing services of the gross
revenues collected monthly, 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, which is assessed periodically based on market studies, 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, are 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 $8,430 and $16,383 for the three months ended June 30, 2008 and 2007, respectively, and $19,917 and $42,035 for the six months ended June 30, 2008 and 2007, respectively.

Administrative 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 incurred administrative expenses of $24,656 and $21,418 payable to Wells Capital and Wells Management for the three months ended June 30, 2008 and 2007, respectively, and $48,454 and
$42,193 for the six months ended June 30, 2008 and 2007, respectively. In addition, Wells Capital and Wells Management pay for certain operating expenses of the Partnership (bill-backs) directly and invoices the Partnership for the
reimbursement thereof on a quarterly basis. As of June 30, 2008 and December 31, 2007, due to affiliates balances represent administrative reimbursements and bill-backs due to Wells Capital and/or Wells Management.

Economic Dependency

The Partnership has engaged Wells Capital and Wells Management to provide certain essential services, including supervision of the management and leasing of its properties, asset acquisition and disposition services, as well as other
administrative responsibilities, 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, the Partnership is
dependent upon Wells Capital and Wells Management.

Wells Capital and Wells Management are all owned and controlled by WREF. The operations of Wells
Capital and Wells Management represent substantially all of the business of WREF. Accordingly, the Partnership focuses on the financial condition of WREF when assessing the financial condition of Wells Capital and Wells Management. In the event that
WREF were to become unable to meet its obligations as they become due, the Partnership 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 well as anticipated dividend income earned from its holdings of common stock of Piedmont REIT, which was acquired in connection with
the Piedmont REIT internalization transaction (see Assertion of Legal Actions Against Related-Parties below). In addition, during 2007, WREF guaranteed certain debt of another WREF-sponsored product that is in the start-up phase of its operations.
As of June 30, 2008, 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.

As of July 31, 2008, the amount of the debt guaranteed by WREF was equal to approximately $106.9 million.

The Partnership is also dependent upon the ability of its current tenants to pay their contractual rent amounts as they become due. The inability of a tenant to pay
future rental amounts would be likely to have a negative impact on the Partnerships results of operations. The Partnership is not currently aware of any reason why its existing tenants will not be able to pay their contractual rental amounts
as they become due in all material respects. Situations preventing the tenants from paying contractual rents could result in a material adverse impact on the Partnerships results of operations.

Assertion of Legal Actions Against Related-Parties

On March 12,
2007, a stockholder of Piedmont REIT, filed a putative class action and derivative complaint, presently styled In re Wells Real Estate Investment Trust, Inc. Securities Litigation, in the United States District Court for the District of
Maryland against, among others, Piedmont REIT; Leo F. Wells, III and Wells Capital, our General Partners; Wells Management, our property manager; certain affiliates of WREF; the directors of Piedmont REIT; and certain individuals who formerly
served as officers or directors of Piedmont REIT prior to the closing of the internalization transaction on April 16, 2007. The complaint alleges, among other things, violations of the federal proxy rules and breaches of fiduciary duty arising
from the Piedmont REIT internalization transaction and the related proxy statement filed with the SEC on February 26, 2007, as amended. The complaint seeks, among other things, unspecified monetary damages and nullification of the Piedmont REIT
internalization transaction. On April 9, 2007, the District Court denied the plaintiffs motion for an order enjoining the internalization transaction. On April 17, 2007, the Court granted the defendants motion to transfer venue
to the United States District Court for the Northern District of Georgia, and the case was docketed in the Northern District of Georgia on April 24, 2007. On June 7, 2007, the Court granted a motion to designate the class lead plaintiff
and class co-lead counsel. On June 27, 2007, the plaintiff filed an amended complaint, which attempts to assert class action claims on behalf of those persons who received and were entitled to vote on the Piedmont REIT proxy statement filed
with the SEC on February 26, 2007 and derivative claims on behalf of Piedmont REIT. On July 9, 2007, the Court denied the plaintiffs motion for expedited discovery related to an



Page 14

##### Table of Contents

anticipated motion for a preliminary injunction. On August 13, 2007, the defendants filed a motion to dismiss the amended complaint. On March 31,
2008, the Court granted in part the defendants motion to dismiss the amended complaint. The Court dismissed five of the seven counts of the amended complaint in their entirety. The Court dismissed the remaining two counts with the exception of
allegations regarding the failure to disclose in the Piedmont REIT proxy statement details of certain expressions of interest in acquiring Piedmont REIT. On April 21, 2008, the plaintiff filed a second amended complaint, which alleges
violations of the federal proxy rules based upon allegations that the proxy statement to obtain approval for the Piedmont REIT internalization transaction omitted details of certain expressions of interest in acquiring Piedmont REIT. The second
amended complaint seeks, among other things, unspecified monetary damages, to nullify and rescind the internalization transaction, and to cancel and rescind any stock issued to the defendants as consideration for the internalization
transaction. On May 12, 2008, the defendants answered and raised certain defenses to the second amended complaint. On June 23, 2008, the plaintiff filed a motion for class certification. As of the date of this filing, the time for the
defendants to respond to the plaintiffs motion for class certification has not yet passed. The parties are presently engaged in discovery. Mr. Wells, Wells Capital, and Wells Management intend to vigorously defend this action. Any
financial loss incurred by Wells Capital, Wells Management, or their affiliates could hinder their ability to successfully manage our operations and our portfolio of investments.

On August 24, 2007, two stockholders of Piedmont REIT filed a derivative complaint, styledDonald and Donna Goldstein, Derivatively on behalf of Defendant Wells Real Estate Investment Trust, Inc. v.
Leo F. Wells, III, et al.,in the Superior Court of Fulton County, Georgia, on behalf of Piedmont REIT against, among others, Leo F. Wells, III and Wells Capital, our General Partners, and a number of individuals who
currently or formerly served as officers or directors of Piedmont REIT. The complaint alleges, among other things, that the consideration paid by Piedmont REIT as part of the internalization transaction was excessive; that the defendants
breached their fiduciary duties to Piedmont REIT; and that the internalization transaction unjustly enriched the defendants. The complaint seeks, among other things, a judgment declaring that the defendants committed breaches of their fiduciary
duties and were unjustly enriched at the expense of Piedmont REIT; monetary damages equal to the amount by which Piedmont REIT was damaged by the defendants; an order awarding Piedmont REIT restitution from the defendants and ordering disgorgement
of all profits and benefits obtained by the defendants from their wrongful conduct and fiduciary breaches; an order rescinding the internalization transaction; and the establishment of a constructive trust upon any benefits improperly received by
the defendants as a result of their wrongful conduct. On October 19, 2007, the Court verbally granted the defendants motion for a protective order (and entered a written order on October 24, 2007) staying discovery until the
Court rules on the defendants motion to dismiss the complaint. On October 31, 2007, the defendants filed their motion to dismiss the plaintiffs derivative complaint. On December 19, 2007, the Court entered an order
allowing the plaintiffs to take limited written discovery on the issue of derivative demand, but the order staying discovery entered in October 2007 otherwise remains in effect. The defendants responded to the limited discovery requested by the
plaintiffs. On January 10, 2008, the plaintiffs filed an amended complaint, which contains substantially the same counts against the same defendants as the original complaint with certain additional factual allegations based primarily
on events occurring after the original complaint was filed. In addition, the plaintiffs responded to the defendants motion to dismiss this lawsuit. A hearing on the motion to dismiss was held on February 22, 2008. On
March 13, 2008, the Court granted the defendants motion to dismiss. On April 11, 2008, the plaintiffs filed a notice to appeal the Courts judgment granting the defendants motion to dismiss.



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

From time to time, the Partnership
and its General Partners are party to legal proceedings which arise in the ordinary course of our business. The Partnership is not currently involved in any litigation for which the outcome would, in the judgment of the General Partners based on
information currently available, have a materially adverse impact on the results of operations or financial condition of the Partnership, nor is management aware of any such litigation threatened against us.

|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, 2007.

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;



| |  |  | 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 now own interests in three
properties. Our focus at this time involves leasing the remaining vacancy at the 20/20 Building and maximizing the operating performance of our assets in order to deliver what we believe will be the best overall performance for our limited partners.

Operating distributions payable to the limited partners holding Cash Preferred Units for the second quarter of 2008 remained consistent with the level
paid in the prior quarter. We anticipate that operating distributions will remain at a similar level in the near-term.

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 our limited partners by attempting to negotiate 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 our limited partners, and to minimize contingencies and our post-closing involvement with buyers.

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, 2008,
we generated net operating cash flows, including operating distributions received from the Joint Ventures, of approximately $721,000. Operating 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. We used net operating cash flows primarily to fund operating distributions of approximately $705,000 to Cash Preferred
limited partners during the six months ended June 30, 2008. 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 our share of tenant re-leasing costs and other capital improvements for properties owned by the Joint Ventures. We anticipate that operating distributions from the Joint Ventures will remain at similar
levels in the near term.

At this time, we expect to continue to generate cash flows from operations, including distributions from the Joint Ventures,
sufficient to cover our estimated future expenses. We also believe that the cash on hand and distributions due from the Joint Ventures are sufficient to cover our working capital needs, including liabilities of approximately $378,000 as of
June 30, 2008.

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 our share of tenant improvements, renovations, expansions, and other significant capital improvements necessary for properties owned through the



Page 17

##### Table of Contents

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. Future cash flows from operating activities will be
primarily affected by distributions received from the Joint Ventures, which are dependent upon the net operating income generated by the Joint Ventures properties, less reserves for known capital expenditures.

Capital Resources

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

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 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 of June 30, 2008, we have received, used, distributed, and held net
sale proceeds allocated to the Partnership from the sale of properties as presented below:

Upon evaluating the capital needs of the properties in which we currently own an interest, our General Partners
have determined to hold reserves of the remaining net sale proceeds of approximately $14,000.

Results of Operations

Equity in Income of Joint Ventures

Equity in income of Joint Ventures was $294,991 and $658,359 for the three months ended June 30,
2008 and 2007, respectively and $585,016 and $985,930 for the six months ended June 30, 2008 and 2007, respectively. The decreases are primarily attributable to (i) recognizing a gain on the sale of 111 Southchase Boulevard in May 2007,
(ii) a decrease in operating income resulting from the aforementioned sale of 111 Southchase Boulevard, (iii) an increase in taxes incurred by Fund XII-REIT Associates as a result of the new Michigan business tax effective January 1,
2008, partially offset by (iv) an adjustment to the prior year Michigan single business tax based on a change in estimate. We estimated Michigan single business tax based on an estimate of the apportionment of revenue allocable to Fund XII-REIT
Associates from the property in Michigan. As a result of the recent tax changes, our future estimates of the Michigan business tax will fluctuate in relationship to revenue and gross receipts earned by Fund XII-REIT Associates from the property in
Michigan relative to revenue and gross receipts earned by Fund XII-REIT Associates from all properties in the future.

Absent leasing activity at the 20/20
Building, we anticipate equity in income of Joint Ventures to remain at similar levels.

Expenses

General and administrative expenses were $45,219 and $36,191 for the three months ended June 30, 2008 and 2007, respectively. The increase is primarily attributable
to an increase in administrative costs and an adjustment related to the 2006 Tennessee partnership franchise and excise taxes made in the second quarter of 2007. We estimate Tennessee partnership franchise and excise taxes based on an estimate of
the apportionment of income allocable to the Partnership from the property 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 the property in Tennessee fluctuates relative to income earned by the Partnership from all properties in the future.

General and administrative expenses were $111,925 and $92,805 for the six months ended June 30, 2008 and 2007, respectively. The increase is
primarily attributable to (i) an increase in printing and postage costs, (ii) an increase in administrative costs, and (iii) an adjustment related to the 2006 Tennessee partnership franchise and excise taxes made in the second quarter
of 2007. We estimate Tennessee partnership franchise and excise taxes based on an estimate of the apportionment of income allocable to the Partnership from the property 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 the property in Tennessee fluctuates
relative to income earned by the Partnership from all properties in the future.

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

Interest and Other Income

Interest and other income were $514 and $7,603 for the three months ended June 30, 2008 and 2007, respectively, and $1,512 and $9,902 for the six
months ended June 30, 2008 and 2007, respectively. The decreases are primarily a result of a decrease in the average amount of net sale proceeds held during the respective periods due to the distribution of net sale proceeds to limited partners
in November 2007, as well as a decrease in the average daily yield. Future levels of interest income will be largely dependent upon the timing of future dispositions and net sale proceeds distributions to the limited partners, and the amount of
operating cash needed to invest in the Joint Ventures related to funding our pro rata share of re-leasing costs and capital expenditures.

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 help 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 are required to make subjective assessments as to the useful lives of our depreciable assets. We 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 provided below:



|                      |  |                                       
|--------------------- |  | --------------------------------------
|                      | 
|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, and recognizes an impairment loss. Estimated fair values are calculated based on the



Page 20



---

##### Table of Contents

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 our real estate assets held by the Partnership as of
June 30, 2008.

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.



|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 currency exchange rate fluctuations,
or the other market risks contemplated by Item 305 of Regulation S-K.



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

We carried out an evaluation, under the
supervision and with the participation of management of Wells Capital, the corporate general partner of Wells Partners, 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 (the Exchange Act) as of the end of the quarterly 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 the reports we file or submit under the Exchange Act 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 the reports we file under the Exchange Act 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 changes in our
internal control over financial reporting during the quarter ended June 30, 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
