KBS REAL ESTATE INVESTMENT TRUST III, INC.

SUPPLEMENT NO. 4 DATED MARCH 14, 2011

TO THE PROSPECTUS DATED OCTOBER 26, 2010

This document supplements, and should be read in conjunction with, the prospectus of KBS Real Estate Investment Trust III, Inc. dated October 26, 2010, as supplemented by supplement no. 1 dated November 23, 2010, supplement no. 2 dated December 6, 2010 and supplement no. 3 dated January 25, 2011. As used herein, the terms “we,” “our” and “us” refer to KBS Real Estate Investment Trust III, Inc. and, as required by context, KBS Limited Partnership III, which we refer to as our “Operating Partnership,” and to their subsidiaries. Capitalized terms used in this supplement have the same meanings as set forth in the prospectus. The purpose of this supplement is to disclose:

— the status of the offering;

— updated risks related to an investment in us;

— “Management’s Discussion and Analysis of Financial Condition and Results of Operations” similar to that filed in our annual report on Form 10-K for the year ended December 31, 2010; and

— our consolidated balance sheet and the notes thereto as of December 31, 2010.

Status of the Offering

We commenced this offering of 280,000,000 shares of common stock on October 26, 2010. As of March 11, 2011, our escrow agent had not received sufficient offering proceeds to meet the minimum offering amount and we had not yet commenced real estate operations.

Risk Factors

Before purchasing our common stock, you should carefully consider the following risks as well as those described in the prospectus and in supplement no. 1.

If we are unable to find suitable investments, we may not be able to achieve our investment objectives or pay distributions.

Our ability to achieve our investment objectives and to pay distributions depends upon the performance of KBS Capital Advisors, our advisor, in the acquisition of our investments, including the determination of any financing arrangements, and the ability of our advisor to source loan origination opportunities for us. Competition from competing entities may reduce the number of suitable investment opportunities offered to us or increase the bargaining power of property owners seeking to sell. Additionally, disruptions and dislocations in the credit markets have materially impacted the cost and availability of debt to finance real estate acquisitions, which is a key component of our acquisition strategy. The lack of available debt could result in a further reduction of suitable investment opportunities and create a competitive advantage to other entities that have greater financial resources than we do. We will also depend upon the performance of our property managers in the selection of tenants and negotiation of leasing arrangements. Rising vacancies across commercial real estate have resulted in increased pressure on real estate investors and their property managers to find new tenants and keep existing tenants. In order to do so, we may have to offer inducements, such as free rent and tenant improvements, to compete for attractive tenants. We are also subject to competition in seeking to acquire real estate-related investments. The more shares we sell in this offering, the greater our challenge will be to invest the net offering proceeds on attractive terms. Our investors must rely entirely on the management abilities of KBS Capital Advisors, the property managers KBS Capital Advisors selects and the oversight of our board of directors. We can give no assurance that KBS Capital Advisors will be successful in obtaining suitable investments on financially attractive terms or that, if KBS Capital Advisors makes investments on our behalf, our objectives will be achieved. If we, through KBS Capital Advisors, are unable to find suitable investments promptly, we will hold the proceeds from this offering in an interest-bearing account or invest the proceeds in short-term assets. If we would continue to be unsuccessful in locating suitable investments, we may ultimately decide to liquidate. In the event we are unable to timely locate suitable investments, we may be unable or limited in our ability to pay distributions and we may not be able to meet our investment objectives.

1

Our advisor and its affiliates will face conflicts of interest relating to the origination and acquisition of assets and leasing of properties due to their relationship with other KBS-sponsored programs and institutional investors, which could result in decisions that are not in our best interest or the best interests of our stockholders.

We rely on our sponsors and other key real estate and debt finance professionals at our advisor, including Peter M. Bren, Keith D. Hall, Peter McMillan III and Charles J. Schreiber, Jr., to identify suitable investment opportunities for us. KBS REIT I, KBS REIT II, KBS Legacy Partners Apartment REIT and KBS Strategic Opportunity REIT are also advised by KBS Capital Advisors and rely on our sponsors and many of the same real estate and debt finance professionals as will future public KBS-sponsored programs. Messrs. Bren and Schreiber and several of the other key real estate professionals at KBS Capital Advisors are also the key real estate professionals at KBS Realty Advisors and its affiliates, the advisors to the private KBS-sponsored programs and the investment advisors to institutional investors in real estate and real estate-related assets. As such, the other KBS-sponsored programs that are currently raising funds for investment and KBS-advised investors rely on many of the same real estate and debt finance professionals, as will future programs. Many investment opportunities that are suitable for us may also be suitable for other KBS programs and investors. When these real estate and debt finance professionals direct an investment opportunity to any KBS-sponsored program or KBS-advised investor, they, in their sole discretion, will offer the opportunity to the program or investor for which the investment opportunity is most suitable based on the investment objectives, portfolio and criteria of each program or investor. Until KBS REIT II has fully invested the proceeds from its initial public offering, and to the extent that an investment opportunity meets the cash flow requirements, operating needs, diversification goals and overall portfolio mix of KBS REIT II, we expect the advisor to direct the investment opportunity to KBS REIT II. KBS REIT II ceased offering shares in its primary public offering on December 31, 2010. Based upon current market conditions, we expect that KBS REIT II will have fully invested the proceeds from its initial public offering within the next three to six months. However, from time to time, and based upon asset sales and the maturity, prepayment or workout of debt-related investments, KBS REIT II may seek to make a small number of investments during our acquisition stage. For so long as we are externally advised, our charter provides that it shall not be a proper purpose of the corporation for us to make any significant investment unless the advisor has recommended the investment to us. Thus, the real estate and debt finance professionals of KBS Capital Advisors could direct attractive investment opportunities to other entities or investors. Such events could result in us investing in properties that provide less attractive returns, which would reduce the level of distributions we may be able to pay our stockholders.

We and other KBS-sponsored programs and KBS-advised investors also rely on these real estate professionals to supervise the property management and leasing of properties. If the KBS team of real estate professionals directs creditworthy prospective tenants to properties owned by another KBS-sponsored program or KBS-advised investor when it could direct such tenants to our properties, our tenant base may have more inherent risk and our properties’ occupancy may be lower than might otherwise be the case.

Further, existing and future KBS-sponsored programs and KBS-advised investors and Messrs. Bren, Hall, McMillan and Schreiber are generally not prohibited from engaging, directly or indirectly, in any business or from possessing interests in any other business venture or ventures, including businesses and ventures involved in the acquisition, origination, development, ownership, leasing or sale of real estate-related investments. Messrs. Bren, Hall, McMillan and Schreiber have agreed to restrictions with respect to sponsoring another multi-family REIT while the KBS Legacy Partners Apartment REIT offering is ongoing.

The offering price of our shares of common stock was not established on an independent basis and bears no relationship to the net value of our assets. The offering price is likely to be higher than the amount our stockholders would receive per share if we were to liquidate at this time because of the upfront fees that we pay in connection with the issuance of our shares. We may use the most recent price paid to acquire a share in this offering or a follow-on public offering as the estimated value of our shares until we have completed our offering stage. Even when our advisor begins to use other valuation methods to estimate the value of our shares, the value of our shares will be based upon a number of assumptions that may not be accurate or complete.

We established the offering price of our shares on an arbitrary basis. The selling price of our shares bears no relationship to our book or asset values or to any other established criteria for valuing shares. Because the offering price is not based upon any independent valuation, the offering price may not be indicative of the proceeds that our stockholders would receive upon liquidation. Further, the offering price may be significantly more than the price at which the shares would trade if they were to be listed on an exchange or actively traded by broker-dealers.

To assist FINRA members and their associated persons that participate in this offering, pursuant to FINRA Conduct Rule 5110, we disclose in each annual report distributed to stockholders a per share estimated value of our shares, the method by which it was developed, and the date of the data used to develop the estimated value. For this purpose, KBS Capital Advisors estimated the value of our common shares as $10.00 per share as of December 31, 2010. The basis for this valuation is the fact that the current public offering price of our shares of common stock in our primary public offering is $10.00 per share (ignoring purchase price discounts for certain categories of purchasers). Our advisor has indicated that it intends to use the most recent price paid to acquire a share in this offering (ignoring purchase price discounts for certain categories of purchasers) or a follow-on public offering as its estimated per share value of our shares until we have completed our offering stage. We will consider our offering stage complete when we are no longer publicly offering equity securities—whether through this offering or follow-on public offerings—and have not done so for up to 18 months. We currently expect to update the estimated value per share every 12 to 18 months thereafter. If our board of directors determines that it is in our best interest, we may conduct follow-on offerings upon the termination of this offering. Our charter does not restrict our ability to conduct equity offerings in the future. For purposes of determining when our offering stage is complete, 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.

Although this initial estimated value represents the price at which most investors will purchase shares in this offering, this reported value is likely to differ from the price at which a stockholder could resell his or her shares because (i) there is no public trading market for the shares at this time; (ii) the estimated value does not reflect, and is not derived from, the fair market value of our properties and other assets, nor does it represent the amount of net proceeds that would result from an immediate liquidation of those assets, because the amount of proceeds available for investment from this offering will be net of selling commissions, dealer manager fees, other organization and offering costs and acquisition and origination fees and expenses; (iii) the estimated value does not take into account how market fluctuations will affect the value of our investments, including how the current disruptions in the financial and real estate markets may affect the values of our investments; and (iv) the estimated value does not take into account how developments related to individual assets may increase or decrease the value of our portfolio.

When determining the estimated value of our shares by methods other than the last price paid to acquire a share in a public offering, our advisor, or another firm we choose for that purpose, will estimate the value of our shares based upon a number of assumptions that may not be accurate or complete. Accordingly, these estimates may or may not be an accurate reflection of the fair market value of our investments and may or may not represent the amount of net proceeds that would result from an immediate sale of our assets.

There can be no assurance that the direct or indirect effects of the Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010 for the purpose of stabilizing or reforming the financial markets, will not have an adverse effect on our interest rate hedging activities.

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) became law in the United States. Title VII of the Dodd-Frank Act contains a sweeping overhaul of the regulation of privately negotiated derivatives. The provisions of Title VII become effective on July 16, 2011 or, with respect to particular provisions, on such other date specified in the Dodd-Frank Act or by subsequent rulemaking. While the full impact of the Dodd-Frank Act on our interest rate hedging activities cannot be assessed until implementing rules and regulations are promulgated, the requirements of Title VII may affect our ability to enter into hedging or other risk management transactions, may increase our costs in entering into such transactions, and may result in us entering into such transactions on more unfavorable terms than prior to effectiveness of the Dodd-Frank Act. The occurrence of any of the foregoing events may have an adverse effect on our business.

Dividends payable by REITs do not qualify for the reduced tax rates.

Legislation enacted in 2003 and modified in 2005 and 2010 generally reduces the maximum tax rate for dividends payable to domestic stockholders that are individuals, trusts and estates to 15% (through 2012). Dividends payable by REITs, however, are generally not eligible for the reduced rates. Although this legislation does not adversely affect the taxation of REITs or dividends paid by REITs, the more favorable rates applicable to regular corporate dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in stock of non-REIT corporations that pay dividends, which could adversely affect the value of the stock of REITs, including our common stock.

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 balance sheet of KBS Real Estate Investment Trust III, Inc. and the notes thereto, included in this supplement. This discussion contains forward-looking statements that can be identified with the use of forward-looking terminology such as “may,” “will,” “seeks,” “anticipates,” “believes,” “estimates,” “expects,” “plans,” “intends,” “should” or similar expressions. Actual results may differ from those described in forward-looking statements. For a discussion of the factors that could cause our actual results to differ from those anticipated, see “Risk Factors” in the prospectus, in supplement no. 1 and in supplement no. 4.

Overview

We were formed on December 22, 2009 as a Maryland corporation and intend to qualify as a real estate investment trust (“REIT”) beginning with the taxable year ending December 31, 2011. On February 4, 2010, we filed a registration statement on Form S-11 with the SEC to offer a minimum of 250,000 shares and a maximum of 280,000,000 shares of common stock for sale to the public, of which 200,000,000 shares were registered in our primary offering and 80,000,000 shares were registered under our dividend reinvestment plan. The SEC declared our registration statement effective on October 26, 2010 and we retained KBS Capital Markets Group, an affiliate of our advisor, to serve as the dealer manager of the offering pursuant to a dealer manager agreement. The dealer manager is responsible for marketing our shares in this offering.

We intend to use substantially all of the net proceeds from this offering to invest in and manage a diverse portfolio of real estate properties and real estate-related assets. We plan to diversify our portfolio by investment type, investment size and investment risk with the goal of attaining a portfolio of income-producing real estate properties and real estate-related assets that provide attractive and stable returns to our investors. We intend to allocate between 60% and 70% of our portfolio to investments in core properties and between 30% and 40% of our portfolio to other real estate-related investments such as mortgage, mezzanine, bridge and other loans; debt and derivative securities related to real estate assets, including mortgage-backed securities; and the equity securities of other REITs and real estate companies. Although this is our current target portfolio, we may make adjustments to our target portfolio based on real estate market conditions and investment opportunities. We will not forego what we believe to be a good investment because it does not precisely fit our expected portfolio composition.

As of December 31, 2010, we had not broken escrow in this offering or acquired, originated or contracted to make any investments. We also had not identified any assets in which there is a reasonable probability that we will invest.

KBS Capital Advisors is our advisor. As our advisor, KBS Capital Advisors will manage our day-to-day operations and our portfolio of real estate properties and real estate-related investments. KBS Capital Advisors will make recommendations on all investments to our board of directors. All proposed investments must be approved by at least a majority of our board of directors, including a majority of the conflicts committee. Unless otherwise provided by our charter, the conflicts committee may approve a proposed investment without action by the full board of directors if the approving members of the conflicts committee constitute at least a majority of the board of directors. KBS Capital Advisors will also provide asset-management, marketing, investor-relations and other administrative services on our behalf.

We intend to make an election to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), beginning with the taxable year ending December 31, 2011. If we qualify as a REIT for federal income tax purposes, we generally will not be subject to federal income tax to the extent we distribute qualifying dividends to our stockholders. If we fail to qualify as a REIT in any taxable year after electing REIT status, we will be subject to federal income tax on our taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year in which our qualification is denied. Such an event could materially and adversely affect our net income and cash available for distribution. However, we believe that we will be organized and will operate in a manner that will enable us to qualify for treatment as a REIT for federal income tax purposes beginning with our taxable year ending December 31, 2011, and we intend to continue to operate so as to remain qualified as a REIT for federal income tax purposes thereafter.

Market Outlook – Real Estate and Real Estate Finance Markets

The following discussion is based on management’s beliefs, observations and expectations with respect to the real estate and real estate finance markets.

During the past three years, significant and widespread concerns about credit risk and access to capital have been present in the U.S. and global financial markets. Economies throughout the world have experienced increased unemployment and sagging consumer confidence due to a downturn in economic activity. Despite improved stock market performance and some positive economic indicators, a lack of job creation, low consumer confidence and a growing federal budget deficit temper the positive indicators. Amid signs of recovery in the economic and financial markets, concerns remain regarding job growth, wage stagnation, credit restrictions and increased taxation. Over the past several months, the U.S. commercial real estate industry has experienced a slow-down in the deterioration of fundamental benchmarks. However, the current economic conditions continue to create a highly competitive leasing environment which will impact our investments in real estate properties, as well as the collateral securing any real estate-related investments we make.

Liquidity and Capital Resources

We are dependent upon the net proceeds from this offering to conduct our proposed operations. We will obtain the capital required to purchase real estate and real estate-related investments and conduct our operations from the proceeds of this offering and any future offerings we may conduct, from secured or unsecured financings from banks and other lenders and from any undistributed funds from our operations. As of December 31, 2010, we have not made any investments, and our total assets consist of $0.2 million of cash and cash equivalents.

We will not sell any shares in this offering unless we raise a minimum of $2,500,000 in gross offering proceeds from persons who are not affiliated with us, our sponsors or our advisor. If we are unable to raise substantially more funds in this offering than the minimum offering amount, we will make fewer investments resulting in less diversification in terms of the type, number and size of investments we make and the value of an investment in us will fluctuate more widely with the performance of the specific assets we acquire. Further, we will have certain fixed operating expenses, including certain expenses as a publicly offered REIT, regardless of whether we are able to raise substantial funds in this offering. Our inability to raise substantial funds would increase our fixed operating expenses as a percentage of gross income, reducing our net income and limiting our ability to make distributions. We do not expect to establish a permanent reserve from our offering proceeds for maintenance and repairs of real properties, as we expect the vast majority of leases for the properties we acquire will provide for tenant reimbursement of operating expenses. However, to the extent that we have insufficient funds for such purposes, we may establish reserves from gross offering proceeds, out of cash flow from operations or out of net cash proceeds from the sale of properties.

We currently have no outstanding debt. Once we have fully invested the proceeds of the offering, we expect that our debt financing will be between 35% and 65% of the cost of our tangible assets (before deducting depreciation or other non-cash reserves). We expect our debt financing related to the acquisition of core properties to be between 45% and 65% of the aggregate cost of all such assets. We expect our debt financing related to the acquisition of real-estate related investments to be between 0% and 65% of the aggregate cost of all such assets, depending upon the market’s appetite for such financings. Though this is our target leverage, our charter does not limit our leverage until our borrowings would exceed 75% of the cost of our tangible assets (before deducting depreciation or other non-cash reserves), and we may exceed this limit with the approval of the conflicts committee of our board of directors. During the early stages of the offering, and to the extent financing in excess of this limit is available on attractive terms, our conflicts committee may approve debt in excess of this limit.

5

In addition to making investments in accordance with our investment objectives, we expect to use our capital resources to make certain payments to our advisor and the dealer manager. During our organization and offering stage, these payments will include payments to the dealer manager for selling commissions and the dealer manager fee and payments to the dealer manager and our advisor for reimbursement of certain organization and offering expenses. However, at the termination of our primary offering and at the termination of the offering under our dividend reinvestment plan, our advisor has agreed to reimburse us to the extent that selling commissions, the dealer manager fee and other organization and offering expenses incurred by us exceed 15% of our gross offering proceeds. Further, other than selling commissions and the dealer manager fee, we are only liable to reimburse organization and offering costs incurred by our advisor, the dealer manager and their affiliates, up to an amount that, when combined with selling commissions and dealer manager fees, does not exceed 15% of the gross proceeds of our offering as of the date of reimbursement. During our acquisition and development stage, we expect to make payments to our advisor in connection with the selection and origination or purchase of investments, the management of our assets and costs incurred by our advisor in providing services to us. The advisory agreement has a one-year term but may be renewed for an unlimited number of successive one-year periods upon the mutual consent of our advisor and our conflicts committee. As of December 31, 2010, we had not acquired, originated or contracted to make any investments. Also, as of December 31, 2010, our advisor had not identified any assets in which there is a reasonable probability that we will invest.

We intend to elect to be taxed as a REIT and to operate as a REIT beginning with our taxable year ending December 31, 2011. To maintain our qualification as a REIT, we will be required to make aggregate annual distributions to our stockholders of at least 90% of our REIT taxable income (computed without regard to the dividends paid deduction and excluding net capital gain). Our board of directors may authorize distributions in excess of those required for us to maintain REIT status depending on our financial condition and such other factors as our board of directors deems relevant. We have not established a minimum distribution level.

Results of Operations

We were formed on December 22, 2009 and, as of December 31, 2010, we have not commenced operations. We will not commence any significant operations until we have made investments with the net proceeds from this offering. As of December 31, 2010, our advisor has incurred organization and offering expenses on our behalf of $2.1 million. The reimbursement of these organization and offering costs to our advisor is contingent on us raising the minimum offering amount in this offering, and we may only reimburse our advisor up to an amount that does not cause total organization and offering expenses incurred by us, when combined with selling commissions and dealer manager fees, to exceed 15% of the gross proceeds from the offering as of the date of reimbursement. Therefore, these costs are not our liabilities as of December 31, 2010.

Critical Accounting Policies

Below is a discussion of the accounting policies that management believes will be critical once we commence operations. We consider these policies critical in that they involve significant management judgments and assumptions, require estimates about matters that will be inherently uncertain and because they are important for understanding and evaluating our reported financial results. These judgments will affect the reported amounts of assets and liabilities and our 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. With different estimates or assumptions, materially different amounts could be reported in our financial statements. Additionally, other companies may utilize different estimates that may impact the comparability of our results of operations to those of companies in similar businesses.

Revenue Recognition

Real Estate

We will recognize minimum rent, including rental abatements, lease incentives and contractual fixed increases attributable to operating leases, on a straight-line basis over the term of the related leases when collectibility is reasonably assured and will record amounts expected to be received in later years as deferred rent receivable. If the lease provides for tenant improvements, we will determine whether the tenant improvements, for accounting purposes, are owned by the tenant or by us. When we are the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:

— whether the lease stipulates how a tenant improvement allowance may be spent;

— whether the amount of a tenant improvement allowance is in excess of market rates;

— whether the tenant or landlord retains legal title to the improvements at the end of the lease term;

— whether the tenant improvements are unique to the tenant or general-purpose in nature; and

— whether the tenant improvements are expected to have any residual value at the end of the lease.

We will record property operating expense reimbursements due from tenants for common area maintenance, real estate taxes and other recoverable costs in the period the related expenses are incurred.

We will make estimates of the collectibility of our tenant receivables related to base rents, including deferred rents receivable, expense reimbursements and other revenue or income. We will specifically analyze accounts receivable, deferred rent receivable, historical bad debts, customer creditworthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In addition, with respect to tenants in bankruptcy, we will make estimates of the expected recovery of pre-petition and post-petition claims in assessing the estimated collectibility of the related receivable. In some cases, the ultimate resolution of these claims can exceed one year. When a tenant is in bankruptcy, we will record a bad debt reserve for the tenant’s receivable balance and generally will not recognize subsequent rental revenue until cash is received or until the tenant is no longer in bankruptcy and has the ability to make rental payments.

Real Estate Loans Receivable

Interest income from any real estate loans receivable we may purchase or originate will be recognized on an accrual basis over the life of the investment using the interest method. Direct loan origination fees and origination or acquisition costs, as well as acquisition premiums or discounts, will be amortized over the term of the loan as an adjustment to interest income. We will place loans on nonaccrual status when any portion of principal or interest is 90 days past due, or earlier when concern exists as to the ultimate collection of principal or interest. When a loan is placed on nonaccrual status, we will reverse the accrual for unpaid interest and generally will not recognize subsequent interest income until the cash is received, or the loan returns to accrual status. We will resume the accrual of interest if we determine the collection of interest according to the contractual terms of the loan is probable.

Real Estate Securities

We will recognize interest income on real estate securities that are beneficial interest in securitized financial assets and are rated “AA” and above on an accrual basis according to the contractual terms of the securities. Discounts or premiums will be amortized to interest income over the life of the investment using the interest method.

We will recognize interest income on real estate securities that are beneficial interests in securitized financial assets that are rated below “AA” using the effective yield method, which requires us to periodically project estimated cash flows related to these securities and recognize interest income at an interest rate equivalent to the estimated yield on the security, as calculated using the security’s estimated cash flows and amortized cost basis, or reference amount. Changes in the estimated cash flows will be recognized through an adjustment to the yield on the security on a prospective basis. Projecting cash flows for these types of securities will require significant judgment, which may have a significant impact on the timing of revenue recognized on these investments.

7

Cash and Cash Equivalents

We will recognize interest income on our cash and cash equivalents as it is earned and will record such amounts as other interest income.

Real Estate

Depreciation and Amortization

Real estate costs related to the acquisition and improvement of properties will be capitalized and amortized over the expected useful life of the asset on a straight-line basis. Repair and maintenance costs will be charged to expense as incurred and significant replacements and betterments will be capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. We consider the period of future benefit of an asset to determine its appropriate useful life. Expenditures for tenant improvements will be capitalized and amortized over the shorter of the tenant’s lease term or expected useful life. We anticipate the estimated useful lives of our assets by class to be generally as follows:

Buildings	25-40 years
Building improvements	10-25 years
Tenant improvements	Shorter of lease term or expected useful life
Tenant origination and absorption costs	Remaining term of related leases, including below-market renewal periods

Real Estate Acquisition Valuation

We will record the acquisition of income-producing real estate or real estate that will be used for the production of income as a business combination. All assets acquired and liabilities assumed in a business combination will be measured at their acquisition-date fair values. Acquisition costs will be expensed as incurred and restructuring costs that do not meet the definition of a liability at the acquisition date will be expensed in periods subsequent to the acquisition date. In addition, changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period are recorded to income tax expense.

Intangible assets include the value of in-place leases, which represents the estimated value of the net cash flows of the in-place leases to be realized, as compared to the net cash flows that would have occurred had the property been vacant at the time of acquisition and subject to lease-up. Acquired in-place lease value will be amortized to expense over the average remaining non-cancelable terms of the respective in-place leases, including any below-market renewal periods.

We will assess the acquisition-date fair values of all tangible assets, identifiable intangibles and assumed liabilities using methods similar to those used by independent appraisers (e.g., discounted cash flow analysis) and that utilize appropriate discount and/or capitalization rates and available market information. Estimates of future cash flows are based on a number of factors, including historical operating results, known and anticipated trends, and market and economic conditions. The fair value of tangible assets of an acquired property considers the value of the property as if it were vacant.

We will record above-market and below-market in-place lease values for acquired properties based on the present value (using an interest 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) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of above-market in-place leases and for the initial term plus a consideration for any extended terms for any leases with renewal options deemed to be below-market. We will amortize any recorded above-market or below-market lease values as a reduction or increase, respectively, to rental income over the remaining non-cancelable terms of the respective lease, including any renewal periods deemed to be below-market.

We will estimate the value of tenant origination and absorption costs by considering the estimated carrying costs during hypothetical expected lease-up periods, considering current market conditions. In estimating carrying costs, we will include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods. We will amortize the value of tenant origination and absorption costs to depreciation and amortization expense over the remaining average non-cancelable term of the leases.

Estimates of the fair values of the tangible assets, identifiable intangibles and assumed liabilities will require us to make significant assumptions 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 will be held for investment. The use of inappropriate assumptions would result in an incorrect valuation of our acquired tangible assets, identifiable intangibles and assumed liabilities, which would impact the amount of our net income.

8

Impairment of Real Estate and Related Intangible Assets and Liabilities

We will monitor events and changes in circumstances that could indicate that the carrying amounts of our real estate and related intangible assets and liabilities may not be recoverable or realized. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets and liabilities may not be recoverable, we will assess the recoverability by estimating whether we will recover the carrying value of the real estate and related intangible assets and liabilities through its undiscounted future cash flows and its eventual disposition. If, based on this analysis, we do not believe that we will be able to recover the carrying value of the real estate and related intangible assets and liabilities, we will record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the real estate and related intangible assets and liabilities.

Real Estate Loans Receivable

We will record real estate loans receivable at amortized cost, net of loan loss reserves (if any), and will evaluate these loans for impairment at each balance sheet date. The amortized cost of a real estate loan receivable is the outstanding unpaid principal balance, net of unamortized acquisition premiums or discounts and unamortized costs and fees directly associated with the origination or acquisition of the loan.

The reserve for loan losses is a valuation allowance that reflects our estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve will be adjusted through “Provision for loan losses” on our consolidated statements of operations and will be decreased by charge-offs to specific loans when losses are confirmed. The reserve for loan losses may include a portfolio-based component and an asset-specific component.

The asset-specific reserve component relates to reserves for losses on loans considered impaired. We will consider a loan to be impaired when, based upon current information and events, we believe that it is probable that we will be unable to collect all amounts due under the contractual terms of the loan agreement. We will also consider a loan to be impaired if we grant the borrower a concession through a modification of the loan terms or if we expect to receive assets (including equity interests in the borrower) with fair values that are less than the carrying value of the loan in satisfaction of the loan. A reserve will be established when the present value of payments expected to be received, observable market prices, the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) or amounts expected to be received in satisfaction of a loan are lower than the carrying value of that loan.

The portfolio-based reserve component covers the pool of loans that do not have asset-specific reserves. A provision for loan losses will be recorded when available information as of each balance sheet date indicates that it is probable that the pool of loans will incur a loss and the amount of the loss can be reasonably estimated. Required reserve balances for the pool of loans will be derived from estimated probabilities of default and estimated loss severities assuming a default occurs. On a quarterly basis, our management will assign estimated probabilities of default and loss severities to each loan in the portfolio based on factors such as the debt service coverage of the underlying collateral, the estimated fair value of the collateral, the significance of the borrower’s investment in the collateral, the financial condition of the borrower and/or its sponsors, the likelihood that the borrower and/or its sponsors would allow the loan to default, our willingness and ability to step in as owner in the event of default, and other pertinent factors.

Failure to recognize impairments would result in the overstatement of earnings and the carrying value of our real estate loans held for investment. Actual losses, if any, could differ significantly from estimated amounts.

Fair Value Measurements

Under GAAP, we will be required to measure certain financial instruments at fair value on a recurring basis. In addition, we will be required to measure other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate loans receivable and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories:

— Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities;

— Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and

— Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable.

9

When available, we will utilize quoted market prices from independent third-party sources to determine fair value and will classify such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require us to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When we determine the market for a financial instrument owned by us to be illiquid or when market transactions for similar instruments do not appear orderly, we will use several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and will establish a fair value by assigning weights to the various valuation sources. Additionally, when determining the fair value of liabilities in circumstances in which a quoted price in an active market for an identical liability is not available, we will measure fair value using (i) a valuation technique that uses the quoted price of the identical liability when traded as an asset or quoted prices for similar liabilities when traded as assets or (ii) another valuation technique that is consistent with the principles of fair value measurement, such as the income approach or the market approach.

Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.

We will consider the following factors to be indicators of an inactive market: (i) there are few recent transactions; (ii) price quotations are not based on current information; (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets); (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability; (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with our estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability; (vi) there is a wide bid-ask spread or significant increase in the bid-ask spread; (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities; and (viii) little information is released publicly (for example, a principal-to-principal market).

We will consider the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions; (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant; (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced); and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.

Income Taxes

We intend to elect to be taxed as a REIT under the Internal Revenue Code and intend to operate as such beginning with its taxable year ending December 31, 2011. We expect to have little or no taxable income prior to the year for which we intend to elect REIT status. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of our annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, we generally will not be subject to federal income tax on income that we distribute as dividends to our stockholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable 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 and adversely affect our net income and net cash available for distribution to stockholders. However, we intend to organize and operate in such a manner as to qualify for treatment as a REIT.

We have concluded that there are no significant uncertain tax positions requiring recognition in our financial statements. Neither we nor our subsidiaries have been assessed interest or penalties by any major tax jurisdictions. Our evaluations were performed for the tax year ended December 31, 2010.

KBS Real Estate Investment Trust III, Inc.

We have audited the accompanying consolidated balance sheet of KBS Real Estate Investment Trust III, Inc. as of December 31, 2010. The consolidated balance sheet is the responsibility of the Company’s management. Our responsibility is to express an opinion on this balance sheet based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated balance sheet is free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated balance sheet referred to above presents fairly, in all material respects, the consolidated financial position of KBS Real Estate Investment Trust III, Inc. at December 31, 2010, in conformity with U.S. generally accepted accounting principles.

1. ORGANIZATION

KBS Real Estate Investment Trust III, Inc. (the “Company”) was formed on December 22, 2009 as a Maryland corporation that intends to qualify as a real estate investment trust (“REIT”) commencing with its taxable year ending December 31, 2011. Substantially all of the Company’s business is expected to be conducted through KBS Limited Partnership III (the “Operating Partnership”), a Delaware limited partnership formed on January 5, 2010. The Company is the sole general partner of and owns a 0.1% partnership interest in the Operating Partnership. KBS REIT Holdings III LLC (“REIT Holdings III”), the limited partner of the operating partnership formed on January 5, 2010, owns the remaining 99.9% interest in the Operating Partnership and is its sole limited partner. The Company is the sole member and manager of REIT Holdings III.

Subject to certain restrictions and limitations, the business of the Company is externally managed by KBS Capital Advisors LLC (the “Advisor”), an affiliate of the Company, pursuant to an advisory agreement the Company entered with the Advisor, as amended and restated on January 21, 2011 (the “Advisory Agreement”). On January 26, 2010, the Company issued 20,000 shares of its common stock to the Advisor at a purchase price of $10.00 per share. As of December 31, 2010, the Advisor owns the 20,000 shares of common stock outstanding.

The Company intends to invest in a diverse portfolio of real estate properties and real estate-related assets. The primary types of properties the Company expects to invest in include office, industrial and retail properties located throughout the United States. All such real estate assets may be acquired directly by the Company or the Operating Partnership, though the Company may invest in other entities that make similar investments. The Company also expects to invest in real estate-related assets such as mortgage, mezzanine, bridge and other loans; debt and derivative securities related to real estate assets, including mortgage-backed securities; and the equity securities of other REITs and real estate companies.

On February 4, 2010, the Company filed a registration statement on Form S-11 with the Securities and Exchange Commission (the “SEC”) to offer a minimum of 250,000 shares (the “Minimum Number of Shares”) and a maximum of 280,000,000 shares of common stock for sale to the public (the “Offering”), of which 80,000,000 shares are being offered pursuant to the Company’s dividend reinvestment plan. The SEC declared the Company’s registration statement effective on October 26, 2010, and the Company retained KBS Capital Markets Group LLC (the “Dealer Manager”), an affiliate of the Company, to serve as the dealer manager of the Offering pursuant to a dealer manager agreement dated October 26, 2010 (the “Dealer Manager Agreement”). The Dealer Manager is responsible for marketing the Company’s shares being offered pursuant to the Offering. As described above, the Company intends to use substantially all of the net proceeds from the Offering to invest in a diverse portfolio of real estate properties and real estate-related assets.

As of December 31, 2010, the Company had not broken escrow in its Offering and neither the Company nor the Operating Partnership had acquired, originated or contracted to make any investments. Also as of December 31, 2010, the Advisor had not identified any assets in which there is a reasonable probability that the Company or the Operating Partnership will invest.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The consolidated balance sheet includes the accounts of the Company, REIT Holdings III and the Operating Partnership. All significant intercompany balances and transactions are eliminated in consolidation.

The accompanying consolidated balance sheet is prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).

Use of Estimates

The preparation of the consolidated balance sheet in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated balance sheet and accompanying notes. Actual results could materially differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term (with an original maturity of three months or less), highly-liquid investments utilized as part of the Company’s cash-management activities to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value. There are no restrictions on the use of the Company’s cash and cash equivalents as of December 31, 2010.

At December 31, 2010, the Company’s cash and cash equivalents balance was $0.2 million.

Revenue Recognition

Real Estate

The Company will recognize minimum rent, including rental abatements, lease incentives and contractual fixed increases attributable to operating leases, on a straight-line basis over the term of the related leases when collectibility is reasonably assured and will record amounts expected to be received in later years as deferred rent receivable. If the lease provides for tenant improvements, the Company will determine whether the tenant improvements, for accounting purposes, are owned by the tenant or by the Company. When the Company is the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:

• whether the lease stipulates how a tenant improvement allowance may be spent;

• whether the amount of a tenant improvement allowance is in excess of market rates;

• whether the tenant or landlord retains legal title to the improvements at the end of the lease term;

• whether the tenant improvements are unique to the tenant or general purpose in nature; and

• whether the tenant improvements are expected to have any residual value at the end of the lease.

The Company will record property operating expense reimbursements due from tenants for common area maintenance, real estate taxes, and other recoverable costs in the period the related expenses are incurred.

The Company will make estimates of the collectibility of its tenant receivables related to base rents, including deferred rent receivable, expense reimbursements and other revenue or income. Management will specifically analyze accounts receivable, deferred rent receivable, historical bad debts, customer creditworthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In addition, with respect to tenants in bankruptcy, management will make estimates of the expected recovery of pre-petition and post-petition claims in assessing the estimated collectibility of the related receivable. In some cases, the ultimate resolution of these claims can exceed one year. When a tenant is in bankruptcy, the Company will record a bad debt reserve for the tenant’s receivable balance and generally will not recognize subsequent rental revenue until cash is received or until the tenant is no longer in bankruptcy and has the ability to make rental payments.

Real Estate Loans Receivable

Interest income from any real estate loans receivable the Company may purchase or originate will be recognized on an accrual basis over the life of the investment using the interest method. Direct loan origination fees and origination or acquisition costs, as well as acquisition premiums or discounts, will be amortized over the term of the loan as an adjustment to interest income. The Company will place loans on nonaccrual status when any portion of principal or interest is 90 days past due, or earlier when concern exists as to the ultimate collection of principal or interest. When a loan is placed on nonaccrual status, the Company will reverse the accrual for unpaid interest and generally will not recognize subsequent interest income until the cash is received, or the loan returns to accrual status. The Company will resume the accrual of interest if it determines the collection of interest, according to the contractual terms of the loan, is probable.

Real Estate Securities

The Company will recognize interest income on real estate securities that are beneficial interests in securitized financial assets and are rated “AA” and above on an accrual basis according to the contractual terms of the securities. Discounts or premiums will be amortized to interest income over the life of the investment using the interest method.

The Company will recognize interest income on real estate securities that are beneficial interests in securitized financial assets that are rated below “AA” using the effective yield method, which requires the Company to periodically project estimated cash flows related to these securities and recognize interest income at an interest rate equivalent to the estimated yield on the security, as calculated using the security’s estimated cash flows and amortized cost basis, or reference amount. Changes in the estimated cash flows will be recognized through an adjustment to the yield on the security on a prospective basis. Projecting cash flows for these types of securities will require significant judgment, which may have a significant impact on the timing of revenue recognized on these investments.

Cash and Cash Equivalents

The Company will recognize interest income on its cash and cash equivalents as it is earned and will record such amounts as other interest income.

Real Estate

Depreciation and Amortization

Real estate costs related to the acquisition and improvement of properties will be capitalized and amortized over the expected useful life of the asset on a straight-line basis. Repair and maintenance costs will be charged to expense as incurred and significant replacements and betterments will be capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. The Company considers the period of future benefit of an asset to determine its appropriate useful life. Expenditures for tenant improvements will be capitalized and amortized over the shorter of the tenant’s lease term or expected useful life. The Company anticipates the estimated useful lives of its assets by class to be generally as follows:

Buildings	25-40 years
Building improvements	10-25 years
Tenant improvements	Shorter of lease term or expected useful life
Tenant origination and absorption costs	Remaining term of related leases, including below-market renewal periods

Real Estate Acquisition Valuation

The Company will record the acquisition of income-producing real estate or real estate that will be used for the production of income as a business combination. All assets acquired and liabilities assumed in a business combination will be measured at their acquisition date fair values. Acquisition costs will be expensed as incurred and restructuring costs that do not meet the definition of a liability at the acquisition date will be expensed in periods subsequent to the acquisition date.

Intangible assets include the value of in-place leases, which represents the estimated value of the net cash flows of the in-place leases to be realized, as compared to the net cash flows that would have occurred had the property been vacant at the time of acquisition and subject to lease-up. Acquired in-place lease value will be amortized to expense over the average remaining non-cancelable terms of the respective in-place leases, including any below-market renewal periods.

F-6

KBS REAL ESTATE INVESTMENT TRUST III, INC.

NOTES TO CONSOLIDATED BALANCE SHEET (CONTINUED)

December 31, 2010

The Company will assess the acquisition-date fair values of all tangible assets, identifiable intangibles and assumed liabilities using methods similar to those used by independent appraisers (e.g., discounted cash flow analysis) and that utilize appropriate discount and/or capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and market and economic conditions. The fair value of tangible assets of an acquired property considers the value of the property as if it was vacant.

The Company will record above-market and below-market in-place lease values for acquired properties based on the present value (using an interest 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) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of above-market in-place leases and for the initial term plus a consideration for any extended terms for any leases with renewal options deemed to be below-market. The Company will amortize any recorded above-market or below-market lease values as a reduction or increase, respectively, to rental income over the remaining non-cancelable terms of the respective lease, including any below-market renewal periods.

The Company will estimate the value of tenant origination and absorption costs by considering the estimated carrying costs during hypothetical expected lease-up periods, considering current market conditions. In estimating carrying costs, management will include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods. The Company will amortize the value of tenant origination and absorption costs to depreciation and amortization expense over the remaining average non-cancelable term of the leases.

Estimates of the fair values of the tangible assets, identifiable intangibles and assumed liabilities will require the Company to make significant assumptions 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 will be held for investment. The use of inappropriate assumptions would result in an incorrect valuation of the Company’s acquired tangible assets, identifiable intangibles and assumed liabilities, which would impact the amount of the Company’s net income.

Impairment of Real Estate and Related Intangible Assets and Liabilities

The Company will monitor events and changes in circumstances that could indicate that the carrying amounts of its real estate and related intangible assets and liabilities may not be recoverable or realized. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets and liabilities may not be recoverable, the Company will assess the recoverability by estimating whether the Company will recover the carrying value of the real estate and related intangible assets and liabilities through its undiscounted future cash flows and its eventual disposition. If, based on this analysis, the Company does not believe that it will be able to recover the carrying value of the real estate and related intangible assets and liabilities, the Company will record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the real estate and related intangible assets and liabilities.

Real Estate Loans Receivable

The Company will record real estate loans receivable at amortized cost, net of loan loss reserves (if any), and will evaluate these loans for impairment at each balance sheet date. The amortized cost of a real estate loan receivable is the outstanding unpaid principal balance, net of unamortized acquisition premiums or discounts and unamortized costs and fees directly associated with the origination or acquisition of the loan.

The reserve for loan losses is a valuation allowance that reflects management’s estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve will be adjusted through “Provision for loan losses” on the Company’s consolidated statements of operations and will be decreased by charge-offs to specific loans when losses are confirmed. The reserve for loan losses may include a portfolio-based component and an asset-specific component.

The asset-specific reserve component relates to reserves for losses on loans considered impaired. The Company will consider a loan to be impaired when, based upon current information and events, it believes that it is probable that the Company will be unable to collect all amounts due under the contractual terms of the loan agreement. The Company will also consider a loan to be impaired if it grants the borrower a concession through a modification of the loan terms or if it expects to receive assets (including equity interests in the borrower) with fair values that are less than the carrying value of the loan in satisfaction of the loan. A reserve will be established when the present value of payments expected to be received, observable market prices, the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) or amounts expected to be received in satisfaction of an impaired loan are lower than the carrying value of that loan.

The portfolio-based reserve component covers the pool of loans that do not have asset-specific reserves. A provision for loan losses will be recorded when available information as of each balance sheet date indicates that it is probable that the pool of loans will incur a loss and the amount of the loss can be reasonably estimated. Required reserve balances for the pool of loans will be derived from estimated probabilities of default and estimated loss severities assuming a default occurs. On a quarterly basis, the Company’s management will assign estimated probabilities of default and loss severities to each loan in the portfolio based on factors such as the debt service coverage of the underlying collateral, the estimated fair value of the collateral, the significance of the borrower’s investment in the collateral, the financial condition of the borrower and/or its sponsors, the likelihood that the borrower and/or its sponsors would allow the loan to default, the Company’s willingness and ability to step in as owner in the event of default, and other pertinent factors.

Failure to recognize impairments would result in the overstatement of earnings and the carrying value of the Company’s real estate loans held for investment. Actual losses, if any, could differ significantly from estimated amounts.

Deferred Financing Costs

The Company will defer financing costs such as commitment fees, legal fees and other third party costs associated with obtaining commitments for financing that result in a closing of such financing. The Company will amortize these costs over the terms of the respective financing agreements using the interest method. The Company will expense unamortized deferred financing costs when the associated debt is refinanced or repaid before maturity unless specific rules are met that would allow for the carryover of such costs to the refinanced debt. Costs incurred in seeking financing transactions that do not close will be expensed in the period in which it is determined that the financing will not close.

Fair Value Measurements

Under GAAP, the Company will be required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company will be required to measure other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate loans receivable and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories:

• Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities;

• Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model derived valuations in which significant inputs and significant value drivers are observable in active markets; and

• Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable.

When available, the Company will utilize quoted market prices from independent third party sources to determine fair value and will classify such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement.

Additionally, when determining the fair value of liabilities in circumstances in which a quoted price in an active market for an identical liability is not available, the Company will measure fair value using (i) a valuation technique that uses the quoted price of the identical liability when traded as an asset or quoted prices for similar liabilities when traded as assets or (ii) another valuation technique that is consistent with the principles of fair value measurement, such as the income approach or the market approach.

Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.

The Company will consider the following factors to be indicators of an inactive market: (i) there are few recent transactions, (ii) price quotations are not based on current information, (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets), (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability, (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with the Company’s estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability, (vi) there is a wide bid ask spread or significant increase in the bid ask spread, (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities, and (viii) little information is released publicly (for example, a principal-to-principal market).

The Company will consider the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions, (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant, (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced), and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.

Redeemable Common Stock

The Company has adopted a share redemption program that may enable future stockholders to sell their shares to the Company in limited circumstances.

There are several limitations on the Company’s ability to redeem shares under the share redemption program:

• Unless the shares are being redeemed in connection with a stockholder’s death, “qualifying disability” or “determination of incompetence” (each as defined under the share redemption program), the Company may not redeem the shares until the stockholder has held the shares for one year.

• During each calendar year, the share redemption program limits the number of shares the Company may redeem to those that the Company could purchase with the amount of the net proceeds from the issuance of shares under the dividend reinvestment plan during the prior calendar year.

• During any calendar year, the Company may redeem no more than 5% of the weighted-average number of shares outstanding during the prior calendar year.

• The Company has no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland law, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency.

Pursuant to the program, the Company will initially redeem shares at prices determined as follows:

• The lower of $9.25 or 92.5% of the price paid to acquire the shares from the Company for stockholders who have held their shares for at least one year;

• The lower of $9.50 or 95.0% of the price paid to acquire the shares from the Company for stockholders who have held their shares for at least two years;

• The lower of $9.75 or 97.5% of the price paid to acquire the shares from the Company for stockholders who have held their shares for at least three years; and

• The lower of $10.00 or 100% of the price paid to acquire the shares from the Company for stockholders who have held their shares for at least four years.

Notwithstanding the above, the redemption price for redemptions sought upon a stockholder’s death, “qualifying disability” or “determination of incompetence” will initially be the amount paid to acquire the shares from the Company. Furthermore, once the Company establishes an estimated value per share of its common stock, the redemption price per share for all stockholders will be equal to the estimated value per share, as determined by the Advisor or another firm chosen for that purpose. The Company currently expects to establish an estimated value per share after the completion of its offering stage. The Company will consider its offering stage complete when it is no longer publicly offering equity securities – whether through the primary offering or a follow-on public offering – and has not done so for up to 18 months. “Public equity offering” for this purpose does not include offerings on behalf of selling stockholders or offerings related to a dividend reinvestment plan, employee benefit plan or the redemption of interests in the Operating Partnership.

The Company’s board of directors may amend, suspend or terminate the share redemption program with 30 days’ notice to its stockholders. The Company may provide this notice by including such information in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the SEC, or by a separate mailing to its stockholders.

The Company will record amounts that are redeemable under the share redemption program as redeemable common stock in its consolidated balance sheets because the shares will be mandatorily redeemable at the option of the holder and therefore their redemption will be outside the control of the Company. The maximum amount redeemable under the Company’s share redemption program is limited to the number of shares the Company could redeem with the amount of the net proceeds from the sale of shares under the dividend reinvestment plan during the prior calendar year. However, because the amounts that can be redeemed in future periods are determinable and only contingent on an event that is likely to occur (e.g., the passage of time), the Company will present the net proceeds from the current year and prior year dividend reinvestment plan, net of current year redemptions, as redeemable common stock in its consolidated balance sheets.

The Company will classify financial instruments that represent a mandatory obligation of the Company to redeem shares as liabilities. The Company’s redeemable common shares are contingently redeemable at the option of the holder. When the Company determines it has a mandatory obligation to redeem shares under the share redemption program, it will reclassify such obligations from temporary equity to a liability based upon their respective settlement values. As of December 31, 2010, no shares had been tendered for redemption or redeemed by the Company because no shares were eligible for redemption.

Related Party Transactions

Pursuant to the Advisory Agreement and Dealer Manager Agreement, the Company is obligated to pay the Advisor and the Dealer Manager specified fees upon the provision of certain services related to the Offering, the investment of funds in real estate and real estate-related investments, management of the Company’s investments and for other services (including, but not limited to, the disposition of investments). The Company is also obligated to reimburse the Advisor and Dealer Manager for organization and offering costs incurred by the Advisor and the Dealer Manager on behalf of the Company, and the Company is obligated to reimburse the Advisor for acquisition and origination expenses and certain operating expenses incurred on behalf of the Company or incurred in connection with providing services to the Company. In addition, the Advisor is entitled to certain other fees, including an incentive fee upon achieving certain performance goals, as detailed in the Advisory Agreement discussed in Note 4, “Related Party Transactions.”

The Company will record all related party fees as incurred, subject to any limitations described in the Advisory Agreement.

Organization and Offering Costs

Organization and offering costs (other than selling commissions and dealer manager fees) of the Company are initially being paid by the Advisor, the Dealer Manager or their affiliates on behalf of the Company. Other offering costs include all expenses to be incurred by the Company in connection with the Offering. Organization costs include all expenses to be incurred by the Company in connection with the formation of the Company, including but not limited to legal fees and other costs to incorporate the Company.

Pursuant to the Advisory Agreement and the Dealer Manager Agreement, the Company is obligated to reimburse the Advisor, the Dealer Manager or their affiliates, as applicable, for organization and other offering costs paid by them on behalf of the Company, but only to the extent that the reimbursement would not cause selling commissions, the dealer manager fee and other organization and offering expenses borne by the Company to exceed 15% of the gross offering proceeds of the Offering as of the date of the reimbursement. In addition, after the termination of the primary offering, the Advisor is obligated to reimburse us to the extent selling commissions, the dealer manager fee and other organization and offering costs borne by the Company exceed 15% of the gross proceeds raised in the primary offering. The Advisor will do the same after termination of the offering pursuant to the dividend reinvestment plan.

In the event the Minimum Number of Shares of the Company’s common stock is not sold to the public, the Company will terminate the Offering and will have no obligation to reimburse the Advisor, the Dealer Manager or their affiliates for any organization and offering costs. As of December 31, 2010, the Advisor has incurred organization and offering costs on behalf of the Company of approximately $2.1 million. These costs are not recorded in the financial statements of the Company as of December 31, 2010 because such costs are not a liability of the Company until the Minimum Number of Shares of the Company’s common stock is issued. In addition, the Company will only be liable to reimburse the Advisor, the Dealer Manager and their affiliates, for such costs up to an amount that does not cause total organization and offering expenses incurred by the Company, when combined with selling commissions and dealer manager fees, to exceed 15% of the gross proceeds of the Offering. When recorded by the Company, organization costs will be expensed as incurred, which include all expenses to be incurred by the Company in connection with the formation of the Company, including but not limited to legal fees and other costs to incorporate the Company; and offering costs, which include selling commissions and dealer manager fees, will be deferred and charged to stockholder’s equity as such amounts are reimbursed to the Advisor, the Dealer Manager or their affiliates from the gross proceeds of the Offering.

Independent Director Compensation

The Company will pay each of its independent directors an annual retainer of $40,000. In addition, the independent directors will be paid for attending meetings as follows: (i) $2,500 for each board meeting attended, (ii) $2,500 for each committee meeting attended (except that the committee chairman is paid $3,000 for each meeting attended), (iii) $2,000 for each teleconference board meeting attended, and (iv) $2,000 for each teleconference committee meeting attended (except that the committee chairman is paid $3,000 for each teleconference committee meeting attended). All directors will also receive reimbursement of reasonable out-of-pocket expenses incurred in connection with attendance at meetings of the board of directors. No independent director fees or director reimbursements are payable unless the Company sells the Minimum Number of Shares; until the Company sells the Minimum Number of Shares, fees and other amounts payable to the board of directors will accrue without interest. Director compensation is an operating expense of the Company that is subject to the operating expense reimbursement obligation of the Advisor discussed in Note 4, “Related Party Transactions.”

Income Taxes

The Company intends to elect to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, and intends to operate as such beginning with its taxable year ending December 31, 2011. The Company expects to have little or no taxable income prior to the year for which it intends to elect REIT status. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the Company’s annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax on income that it distributes as dividends to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost, unless the Internal Revenue Service grants the Company relief under certain statutory provisions. Such an event could materially and adversely affect the Company’s net income and net cash available for distribution to stockholders. However, the Company intends to organize and operate in such a manner as to qualify for treatment as a REIT.

The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries has been assessed interest or penalties by any major tax jurisdictions.

Segments

The Company expects to invest in and manage a diverse portfolio of real estate properties and real estate-related assets, including the acquisition of commercial properties and investment in real estate-related assets such as mortgage, mezzanine, bridge and other loans; debt securities such as mortgage-backed securities and debt securities issued by other real estate companies; equity securities of real estate companies; and certain types of illiquid securities. As a result, the Company may operate in two business segments: real estate and real estate-related.

Recently Issued Accounting Standards Updates

In January 2010, the FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements (“ASU No. 2010-06”). ASU No. 2010-06 requires additional disclosures regarding significant transfers in and out of Level 1 and Level 2 fair value measurements, including a description of the reasons for the transfers. Further, this ASU requires additional disclosures about purchases, sales, issuances and settlements relating to the activity in Level 3 fair value measurements. ASU No. 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements relating to the activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. The adoption of ASU No. 2010-06 did not have a material impact on the Company’s consolidated financial statements.

In July 2010, the FASB issued ASU No. 2010-20, Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses (“ASU No. 2010-20”). ASU No. 2010-20 requires the Company to provide a greater level of disaggregated information about the credit quality of its financing receivables and its allowance for credit losses. This ASU also requires the Company to disclose additional information related to credit quality indicators, past due information, information related to loans modified in a troubled debt restructuring and significant purchases and sales of financing receivables disaggregated by portfolio segment. ASU No. 2010-20 was initially effective for interim and annual periods ending on or after December 15, 2010. As this ASU amends only the disclosure requirements for loans and the allowance for credit losses, the adoption of ASU No. 2010-20 is not expected to have a significant impact on the Company’s financial statements. In January 2011, the FASB issued ASU No. 2011-01, Receivables (Topic 310): Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20 (“ASU No. 2011-01”). ASU No. 2011-01 announced that it was deferring the effective date of new disclosure requirements for troubled debt restructurings prescribed by ASU No. 2010-20. The effective date for those disclosures will be concurrent with the effective date for proposed ASU No. 2010-20. Currently, that guidance is anticipated to be effective for interim and annual periods ending after June 15, 2011. The adoption of ASU No. 2010-20 may require additional disclosures, but the Company does not expect the adoption to have a material impact to its consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-29, Business Combinations (Topic 805): Disclosure of Supplementary Pro Forma Information for Business Combinations (a consensus of the FASB Emerging Issues Task Force) (“ASU No. 2010-29”). ASU No. 2010-29 updated accounting guidance to clarify that pro forma disclosures should be presented as if a business combination occurred at the beginning of the prior annual period for purposes of preparing both the current reporting period and the prior reporting period pro forma financial information. These disclosures should be accompanied by a narrative description about the nature and amount of material, nonrecurring pro forma adjustments. The new accounting guidance is effective for business combinations consummated in periods beginning after December 15, 2010, and should be applied prospectively as of the date of adoption. Early adoption is permitted. The Company adopted ASU No. 2010-29 for the year ended December 31, 2010 and the adoption of this ASU did not have a material impact to its consolidated financial statements.

3. STOCKHOLDER’S EQUITY

General

Under the Second Articles of Amendment and Restatement of the Company (the “Charter”), the total number of shares of capital stock authorized for issuance is 1,010,000,000 shares, consisting of 1,000,000,000 shares of common stock and 10,000,000 shares of preferred stock, each as defined by the Company’s Charter.

The shares of common stock have a par value of $0.01 per share and entitle the holders to one vote per share on all matters upon which stockholders are entitled to vote, to receive dividends and other distributions as authorized by the board of directors in accordance with the Maryland General Corporation Law and to all rights of a stockholder pursuant to the Maryland General Corporation Law. The common stock has no preferences or preemptive, conversion or exchange rights. As of December 31, 2010, the Company had issued 20,000 shares of common stock.

The Company is authorized to issue one or more classes or series of preferred stock. Prior to the issuance of such shares, the board of directors shall have the power from time to time to classify or reclassify, in one or more series, any unissued shares and designate the preferences, rights and privileges of such shares. As of December 31, 2010, no shares of the Company’s preferred stock were issued and outstanding.

Dividend Reinvestment Plan

The Company has adopted an amended and restated dividend reinvestment plan (the “DRP”) through which common stockholders may elect to reinvest an amount equal to the distributions declared on their shares in additional shares of the Company’s common stock in lieu of receiving cash distributions. The initial purchase price per share under the DRP will be $9.50. Once the Company establishes an estimated value per share, shares issued pursuant to the dividend reinvestment plan will be priced at the estimated value per share of the Company’s common stock, as determined by the Advisor or another firm chosen for that purpose. The Company expects to establish an estimated value per share after the completion of its offering stage. The offering stage will be considered complete when the Company is no longer publicly offering equity securities — whether through the primary offering or follow-on public offerings — and has not done so for up to 18 months. No selling commissions or dealer manager fees will be paid on shares sold under the DRP. “Public equity offering” for this purpose does not include offerings on behalf of selling stockholders or offerings related to a dividend reinvestment plan, employee benefit plan or the redemption of interests in the Operating Partnership. The board of directors of the Company may amend or terminate the DRP for any reason upon 10 days’ notice to participants.

4. RELATED PARTY TRANSACTIONS

The Company has entered the Advisory Agreement with the Advisor and the Dealer Manager Agreement with the Dealer Manager. These agreements entitle the Advisor and the Dealer Manager to specified fees upon the provision of certain services with regard to the Offering and the investment of funds in real estate properties and real estate-related investments, among other services, as well as reimbursement of organization and offering costs incurred by the Advisor and the Dealer Manager on behalf of the Company (as discussed in Note 2) and certain costs incurred by the Advisor in providing services to the Company. The fees and reimbursement obligations are as follows:

Form of Compensation	Amounts
Selling Commission	The Company will pay the Dealer Manager up to 6.5% of the gross offering proceeds before reallowance of commissions earned by participating broker-dealers. The Dealer Manager will reallow 100% of commissions earned to participating broker-dealers. No sales commission will be paid on shares sold through the dividend reinvestment plan. Assuming all shares in the primary offering are sold at the highest possible selling commissions (with no discounts to any categories of purchasers), estimated selling commissions are approximately $162,500 if the Company sells the minimum of 250,000 shares and approximately $130,000,000 if the Company sells the maximum of 200,000,000 shares in the primary offering.
Dealer Manager Fee	The Company will pay the Dealer Manager up to 3.0% of gross offering proceeds. No dealer manager fee is payable on shares sold under the dividend reinvestment plan. The Dealer Manager may reallow to any participating broker-dealer up to 1.0% of the gross offering proceeds attributable to that participating broker-dealer as a marketing fee and in special cases the dealer manager may increase the reallowance. A reduced dealer manager fee is payable with respect to certain volume discount sales. The estimated dealer manager fee is approximately $75,000 if the Company sells the minimum of 250,000 shares and approximately $60,000,000 if the Company sells the maximum of 200,000,000 shares in the primary offering.
Reimbursement of Organization and Offering Expenses	The Company will reimburse the Advisor or its affiliates for organization and other offering expenses (as discussed in Note 2) incurred by the Advisor or its affiliates on behalf of the Company to the extent that reimbursement would not cause selling commissions, the dealer manager fee and the organization and other offering expenses borne by the Company to exceed 15.0% of gross offering proceeds as of the date of reimbursement. The Company estimates organization and offering costs (other than selling commissions and the dealer manager fees) of approximately $137,500 if the Company sells the minimum of 250,000 shares and approximately $19,137,000 if the Company sells the maximum of 280,000,000 shares.
Acquisition Fee	The Company will pay the Advisor 1.0% of the cost of investments acquired, including acquisition expenses and any debt attributable to such investments. With respect to investments in and originations of loans, the Company will pay an origination fee to the Advisor or its subsidiary in lieu of an acquisition fee.

KBS REAL ESTATE INVESTMENT TRUST III, INC.

NOTES TO CONSOLIDATED BALANCE SHEET (CONTINUED)

December 31, 2010

Form of Compensation	Amounts
Origination Fee	The Company will pay the Advisor 1.0% of the amount funded by the Company to acquire or originate mortgage, mezzanine, bridge or other loans, including any acquisition or origination expenses related to such investment and any debt used to fund the acquisition or origination of the loan. The Company will not pay an acquisition fee with respect to such loans. This fee relates to services provided to the Company in connection with sourcing and structuring investments in and originations of loans.
Acquisition and Origination Expenses	The Company will reimburse the Advisor or its affiliates for customary acquisition and origination expenses (including expenses relating to potential investments that do not close), such as legal fees and expenses (including fees of independent contractor in-house counsel that are not employees of the advisor), costs of due diligence, travel and communications expenses, accounting fees and expenses and other closing costs and miscellaneous expenses relating to the acquisition or origination of real estate properties, real estate-related loans, real estate-related debt securities and other real estate-related investments. The Company estimates that these expenses will be an amount equal to approximately 0.59% of the cost of its investments, excluding fees and expenses associated with such investments.
Asset Management Fee (1)	With respect to investments in real property, the asset management fee the Company will pay the Advisor will be a monthly fee equal to one-twelfth of 0.75% of the amount paid or allocated to acquire the investment. This amount includes any portion of the investment that was debt financed and is inclusive of acquisition expenses related thereto (but excludes acquisition fees paid or payable to the Advisor). In the case of investments made through joint ventures, the asset management fee will be determined based on the Company’s proportionate share of the underlying investment. With respect to investments in loans and any investments other than real property, the asset management fee the Company will pay the Advisor will be a monthly fee calculated, each month, as one-twelfth of 0.75% of the lesser of (i) the amount actually paid or allocated to acquire or fund the loan or other investment (which amount includes any portion of the investment that was debt financed and is inclusive of acquisition or origination expenses related thereto but is exclusive of acquisition or origination fees paid or payable to the Advisor) and (ii) the outstanding principal amount of such loan or other investment, plus the acquisition or origination expenses related to the acquisition or funding of such investment (excluding acquisition or origination fees paid or payable to the Advisor), as of the time of calculation.

Form of Compensation	Amounts
Reimbursement of Operating Expenses (1)	Under the Advisory Agreement, the Advisor and its affiliates may seek reimbursement of the expenses incurred by the Advisor or its affiliates in connection with their provision of services to the Company, including the Company’s allocable share of the Advisor’s overhead, such as rent, employee costs, utilities and IT costs. The Advisor may seek reimbursement for employee costs under the Advisory Agreement. The Advisor will seek reimbursement for the Company’s allocable portion of the salaries, benefits and overhead of internal audit department personnel providing services to the Company. In the future if the Advisor seeks reimbursement for additional employee costs, such costs may include the Company’s proportionate share of the salaries of persons involved in the preparation of documents to meet SEC reporting requirements. The Company will not reimburse the Advisor or its affiliates for employee costs in connection with services for which the Advisor or its affiliates receive acquisition, origination or disposition fees (other than reimbursement of travel and communication expenses) or for the salaries and benefits the Advisor or its affiliates may pay to the Company’s executive officers.
Disposition Fee (1)	For substantial assistance in connection with the sale of properties or other investments, the Company will pay the Advisor, the sponsors or their affiliates a disposition fee of 1.0% of the contract sales price of each real property or other investments sold (including residential or commercial mortgage-backed securities issued by a subsidiary of the Company as part of a securitization transaction); provided, however, that if in connection with such disposition commissions are paid to third parties unaffiliated with the Advisor, the sponsors or their affiliates, the fee paid to the Advisor, the sponsors, or their affiliates may not exceed the commissions paid to such unaffiliated third parties, and provided further that the disposition fees paid to the Advisor, the sponsors, their affiliates and unaffiliated third parties may not exceed 6.0% of the contract sales price. The Company will not pay a disposition fee upon the maturity, prepayment or workout of a loan or other debt-related investment, provided that if the Company takes ownership of a property as a result of a workout or foreclosure of a loan, the Company will pay a disposition fee upon the sale of such property. To the extent the disposition fee is paid upon the sale of any assets other than real property, it will count against the limit on “total operating expenses” described below. The Company does not intend to sell assets to affiliates. However, if the Company does sell an asset to an affiliate, its organizational documents would not prohibit it from paying the Advisor a disposition fee. Before the Company sells an asset to an affiliate, the Company’s Charter would require that a majority of the Company’s board of directors (including a majority of the members of the conflicts committee) not otherwise interested in the transaction conclude that the transaction is fair and reasonable to the Company.
Subordinated Participation in Net Cash Flows (1)	After investors receive a return of their net capital contributions and an 8.0% per year cumulative, noncompounded return, the Advisor is entitled to receive 15.0% of the net cash flows produced by the Company, whether from continuing operations, net sale proceeds or otherwise. To the extent this fee is derived from cash flows other than net sales proceeds, this fee will count against the limit on “total operating expenses” described below.

Form of Compensation

Amounts

Subordinated Incentive Listing Fee (1)

Upon listing the Company’s common stock on a national securities exchange, the Advisor or its affiliates will receive 15.0% of the amount by which (1) the market value of the Company’s outstanding stock plus distributions paid by the Company prior to listing exceeds (2) the sum of invested capital and the amount of cash flow necessary to generate an 8.0% per year cumulative, noncompounded return to stockholders. This fee will count against the limit on “total operating expenses” described below.

⁽¹⁾ Commencing on the earlier of four fiscal quarters after (i) the Company makes its first investment or (ii) six months after commencement of the Offering, the Advisor will reimburse the Company at the end of any fiscal quarter for total operating expenses that in the four consecutive fiscal quarters then ended exceed the greater of 2% of its average invested assets or 25% of its net income, unless the conflicts committee of the Company’s board of directors has determined that such excess expenses were justified based on unusual and non-recurring factors.

“Average invested assets” means the average monthly book value of the Company’s assets during the 12-month period before deducting depreciation, bad debts or other non-cash reserves.

“Total operating expenses” means all expenses paid or incurred by the Company, as determined under GAAP, that are in any way related to the Company’s operation, including advisory fees, but excluding (a) the expenses of raising capital such as organization and offering expenses, legal, audit, accounting, underwriting, brokerage, listing, registration and other fees, printing and other such expenses and taxes incurred in connection with the issuance, distribution, transfer, registration and stock exchange listing of the Company’s stock; (b) interest payments; (c) taxes; (d) non-cash expenditures such as depreciation, amortization and bad debt reserves; (e) reasonable incentive fees based on the gain on the sale of the Company’s assets; and (f) acquisition fees, origination fees, acquisition and origination expenses (including expenses relating to potential investments that the Company does not close), disposition fees on the sale of real property and other expenses connected with the acquisition, origination, disposition and ownership of real estate interests, loans or other properties (other than disposition fees on the sale of assets other than real property), such as the costs of foreclosure, insurance premiums, legal services, maintenance, repair and improvement of property. To the extent the Advisor receives the fee described above at “Subordinated Participation in Net Cash Flows” and such fee is derived from cash flows other than net sales proceeds, that fee will count against the limit on “total operating expenses.” To the extent the fee described above at “Disposition Fee” is paid upon the sale of any assets other than real property, that fee will count against the limit on “total operating expenses.” To the extent the Advisor receives the fee described above at “Subordinated Incentive Listing Fee,” that fee will count against the limit on “total operating expenses.”

The Advisory Agreement has a one-year term. The Company may terminate the Advisory Agreement upon 60 days’ written notice. The Advisor in its sole discretion may defer any fee payable to it under the Advisory Agreement. All or any portion of such fee not taken may be deferred without interest and paid when the Advisor determines.

Conflicts of Interest

All of the Company’s executive officers, some of the Company’s directors and the key real estate and debt finance professionals assembled by the Advisor are also executive officers, directors, managers, key professionals and/or holders of a direct or indirect controlling interest in the Advisor, the Dealer Manager and other KBS-affiliated entities. Through KBS-affiliated entities, some of these persons also serve as the investment advisers to institutional investors in real estate and real estate-related assets and, through KBS Capital Advisors, these persons serve as the advisor to KBS Real Estate Investment Trust, Inc., KBS Real Estate Investment Trust II, Inc., KBS Strategic Opportunity REIT, Inc., and KBS Legacy Partners Apartment REIT, Inc. As a result, they owe fiduciary duties to each of these entities, their members and limited partners and their investors, which fiduciary duties may from time to time conflict with the fiduciary duties that they owe to the Company and its stockholders.

Some of the material conflicts that the Advisor, the Dealer Manager, or their affiliates face are 1) the allocation of the time of key executive officers, directors, and other real estate professionals among the Company, other KBS-sponsored programs and KBS-advised investors, and the other activities in which they are involved; 2) the fees received by the Advisor and its affiliates in connection with transactions involving the purchase, origination, management and sale of investments regardless of the quality of the asset acquired or the service provided the Company; and 3) the fees received by the Advisor, the Dealer Manager and their affiliates in connection with the Company’s Offering.

5. COMMITMENTS AND CONTINGENCIES

Economic Dependency

The Company is dependent on the Advisor and the Dealer Manager for certain services that are essential to the Company, including the sale of the Company’s shares of common and preferred stock available for issue; the identification, evaluation, negotiation, origination, acquisition and disposition of investments; management of the daily operations of the Company’s investment portfolio; and other general and administrative responsibilities. In the event that these companies are unable to provide the respective services, the Company will be required to obtain such services from other sources.

Legal Matters

From time to time, the Company may become party to legal proceedings that arise in the ordinary course of its business. Management is not aware of any legal proceedings of which the outcome is reasonably likely to have a material adverse effect on its results of operations or financial condition.

6. SUBSEQUENT EVENTS

The Company evaluates subsequent events up until the date the consolidated balance sheet is issued.

Second Amended and Restated Articles of Incorporation

Effective January 21, 2011, the Company amended and restated its charter to limit certain incentive fees that may be paid to the Advisor related to the gain from the sale of assets, by providing that an interest in gain from the sale of the Company’s assets shall not be payable to the Advisor if it exceeds 15% of the balance of the net proceeds from the sale remaining after the Company’s stockholders receive, in the aggregate, an amount equal to 100% of the original issue price of their common stock, plus an amount equal to 6% of the original issue price of their common stock per year cumulative.
