ITEM 8.01 OTHER EVENTS.

On July 20, 2009, Kilroy Realty, L.P., as borrower, and Kilroy Realty Corporation, as guarantor, entered into Amendment No. 3 (the "Amendment") to the Fourth Amended and Restated Credit Agreement (the "Credit Agreement") with the Banks listed on the signature pages thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, Bank of America, N.A., Commerzbank AG and Wachovia Bank, National Association, as Syndication Agents, J.P. Morgan Securities Inc. and Banc of Ameria Securities LLC, as Joint Lead Arrangers and Joint Bookrunners, and Keybank National Association and PNC Bank, National Association, as Co-Documentation Agents. All capitalized terms used herein but not otherwise defined shall have the meanings ascribed to them in the Credit Agreement or the Amendment, as applicable.

The Amendment amends and restates Section 5.20(a) of the Credit Agreement so that the occupancy covenant is suspended unless the unencumbered asset pool debt service coverage falls to 3.5x or below. At June 30, 2009, the unencumbered asset pool debt service coverage was 5.1x. Unencumbered asset pool debt service coverage is calculated by dividing the unencumbered asset pool net operating cash flow by the unsecured debt service on a trailing four quarter basis.

The above summary is qualified in its entirety by reference to the full text of the Amendment, a copy of which is attached to this report as Exhibit 10.1. The full text of the Amendment is incorporated herein by reference.
