Summary of MPG OFFICE TRUST, INC.

Item 2.02 Results of Operations and Financial Condition.

On July 23, 2012, MPG Office Trust, Inc. (the "Company") filed a Current Report on Form 8-K containing, among other things, certain second quarter 2012 supplemental operating and financial data. Subsequent to the filing of the Form 8-K, the Company determined that a reclassification of the operating results of Stadium Gateway, a joint venture property that was disposed on July 12, 2012, was not reflected as part of income (loss) from discontinued operations for the three months ended June 30, 2012 in the unconsolidated joint venture statements of operations found on page 17 of Exhibit 99.2. Accordingly, the Company is filing this Current Report on Form 8-K/A to furnish revised supplemental information for the quarter ended June 30, 2012, which replaces the supplemental information that was furnished as Exhibit 99.2 in the Form 8-K filed on July 23, 2012. The reclassification of the operating results of Stadium Gateway for the three months ended June 30, 2012 did not change the net income or loss of either the unconsolidated joint venture or the Company for the 2012 second quarter.

The supplemental information, including the revised unconsolidated joint venture statement of operations for the three months ended June 30, 2012, is available on our website, free of charge, at www.mpgoffice.com. A copy of the revised supplemental information is furnished herewith as Exhibit 99.1.

Exhibit 99.1 is being furnished pursuant to Item 2.02 and shall not be deemed "filed" for any purpose, including for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section. The information in this Current Report on Form 8-K/A shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act regardless of any general incorporation language in such filing.
