On December 30, 2013, Inland American Real Estate Trust, Inc., a Maryland corporation (the “Company”), entered into a Sixth Master Management Agreement and Property Management Agreement Amendment Agreement (the “Amendment”) with Inland American Industrial Management LLC, Inland American Office Management LLC and Inland American Retail Management LLC (each a “Manager”), which amended all of the Company’s master management agreements with the Managers, dated July 1, 2012, as amended (the “Master Management Agreements”), and individual property management agreements between the Company’s subsidiaries and the Managers, as amended (the “Individual Management Agreements”), which taken together govern the management of all of the Company’s properties.

Each Manager’s sole member is Inland American Holdco Management LLC, which has three members, all corporations that are controlled by the principals of The Inland Group, Inc. but which are owned by a number of individuals. Neither The Inland Group, Inc. nor any of its subsidiaries own any shares of stock in these corporations.

The Inland Group, Inc. is the ultimate parent of the Company’s sponsor, Inland Real Estate Investment Corporation, and the Company’s business manager, Inland American Business Manager & Advisor, Inc.

The Amendment changes the date by which a notice of termination must be delivered in order to prevent the automatic renewal of the Master Management Agreements and Individual Management Agreements. The new termination notice deadline for each agreement is January 31, 2014. Prior to executing the Amendment, the termination notice deadline for each agreement was December 31, 2013.

The Amendment also changes the termination date for each of the Master Management Agreements and Individual Management Agreements from the earlier of 120 calendar days following the delivery of a termination notice or April 30, 2014 to the earlier of 120 calendar days following the delivery of a termination notice or May 31, 2014.

In all other respects, the terms and conditions of the Master Management Agreements and Individual Management Agreements remain unchanged.

The information set forth above with respect to the Amendment does not purport to be complete in scope and is qualified in its entirety by the full text of the Amendment attached hereto as Exhibit 10.1 and incorporated into this Item 1.01 disclosure by reference.
