Item 7.01                                             Regulation FD Disclosure.

On November 18, 2009, Behringer Harvard REIT I, Inc. (the “Company”) began distribution of its 2009 Third Quarter Report Summary.  A copy of the 2009 Third Quarter Report Summary, appearing as Exhibit 99.1, is furnished and not filed pursuant to Regulation FD.

On November 18, 2009, the Company will hold a conference call for financial advisors to review third quarter 2009 financial results and highlight portfolio performance. A copy of the script for that call, appearing as Exhibit 99.2, and a copy of the presentation materials to be used during that call, appearing as Exhibit 99.3, are furnished and not filed pursuant to Regulation FD.

The script and presentation materials include information about Funds from Operations (“FFO”), Modified Funds from Operations (“MFFO”) and Same Store Sales.  FFO is a supplemental non-GAAP financial measure used by the real estate industry to measure the operating performance of real estate assets.  MFFO excludes impairment charges, adjustments to fair value for derivatives not qualifying for hedge accounting and acquisition-related costs that were required to be expensed effective January 1, 2009 in connection with the adoption of FAS 141R.  Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate diminishes predictably over time.  Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered the presentation of operating results for real estate companies that use historical cost accounting alone to be insufficient.

Accordingly, we believe that FFO is helpful to stockholders and our management as a measure of operating performance because it excludes depreciation and amortization, gains and losses from property dispositions, and extraordinary items, and as a result, when compared year over year, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, general and administrative expenses, and interest costs, which is not immediately apparent from net income.  We believe that MFFO is helpful to stockholders and our management as a measure of operating performance because it excludes charges that management considers more reflective of investing activities or non-operating valuation changes.  By providing FFO and MFFO, we present information that reflects how our management analyzes our long-term operating activities.  We believe fluctuations in MFFO are indicative of changes in operating activities and provide comparability in evaluating our performance over time and as compared to other real estate companies that may not be affected by impairments or have derivatives or acquisition activities.  The following table presents our calculation of FFO and MFFO for the three and nine months ended September 30, 2009 and 2008 (in thousands, except per share amounts):

(1)          This represents our share of depreciation and amortization expense of the properties which we account for under the equity method of accounting.  The expenses of our unconsolidated interests are reflected in our equity in earnings of investments.

(2)          Reflects the gain on sale of 9100 Mineral Circle (sold in February 2008), Enclave on the Lake (sold in July 2008) and 2383 Utah (sold in August 2008.)

(3)          Reflects an adjustment for the noncontrolling third-party partners’ proportionate share of the real estate depreciation and amortization, an adjustment for the limited partnership unit holders’ proportionate share of the real estate depreciation and amortization and gain on sale of 9100 Mineral Circle, Enclave on the Lake and 2383 Utah.

(4)          Reflects an adjustment for the noncontrolling third-party partners’ proportionate share of asset impairment losses and an adjustment for the limited partnership unit holders’ proportionate share of the asset impairment losses and fair value adjustments to derivatives.

We define net operating income (“NOI”) as rental revenue, less property operating expenses, real estate taxes and property management fees.   We believe that NOI provides a supplemental measure of our operating performance because NOI reflects the operating performance of our properties and excludes items that are not associated with management of the properties, such as general and administrative expenses, asset management fees and interest expense.  We define same store NOI as NOI less lease termination fee income and non-cash revenue items including straight-line rent adjustments and the amortization of above and below market rent.  Now that we have sufficient history with our portfolio, we view same store NOI both year over year and quarter over quarter as an important measure of the operating performance of our properties because it allows us to compare operating results of properties owned for the entirety of the current and comparable periods and therefore eliminates variations caused by acquisitions or dispositions during the periods under review.  The following table presents our calculations of same store NOI for the three months ended September 30, 2009 and 2008 and June 30, 2009 (in thousands, except property count):

The following table presents our calculations of same store NOI for the nine months ended September 30, 2009 and 2008 (in thousands, except property count):
