Explanation of Responses:

( 1 )The price reported in Column 4 is the weighted average sales price from multiple sales on the Transaction Date, at prices ranging from $3.00 to $3.26, inclusive. Either Reporting Person will, upon the request of MPG Office Trust, Inc., any security holder of MPG Office Trust, Inc., or the staff of the Securities and Exchange Commission, provide the requesting party full information regarding the number of shares sold at each separate price within the range reported in this and any other footnote to Column 4. ( 2 )The price reported in Column 4 is the weighted average sales price from multiple sales on the Transaction Date, at prices ranging from $3.23 to $3.43, inclusive. ( 3 )The price reported in Column 4 is the weighted average sales price from multiple sales on the Transaction Date, at prices ranging from $3.25 to $3.35, inclusive. ( 4 )The 5,594,220 shares are directly beneficially owned by Wells Fargo Bank, N.A. ("WFB"). All other reported shares are indirectly beneficially owned by WFB and are owned directly by a borrower and pledged to WFB as collateral for a loan. The reported transactions involved sales of the shares by the borrower, and payment of sale proceeds to WFB. WFB is an indirect wholly-owned subsidiary of Wells Fargo & Company ('WFC"), and WFC is therefore an indirect beneficial owner of all of the shares reported herein.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
