ITEM 8.01                      Other Events

1st Source Corporation, parent company of 1st Source Bank, has entered into agreements that restructure its interest in its corporate facility located in downtown South Bend, Indiana.  The company has agreed to a new 10.5 year lease on terms that reduce the costs of the facility to the company. Under the terms of the new lease, 1st Source is relieved of responsibility for managing the office building and reduces its leased space to 84,696 sq. ft. effective January 1, 2011.

1st Source has also transferred to the building owner its interest in the atrium that connects the office building to the adjacent hotel building that, together with an underlying parking garage, comprise the 1st Source Center. 1st Source also assigned its operations and maintenance obligations in connection with the atrium and parking garage to the building owner. The building owner further assumed responsibility for ground lease payments and agreed to contribute $375,000 to atrium renovations on 1st Source’s behalf in connection with a related sale of the parking garage.

1st Source also has sold to the South Bend Redevelopment Commission its interest in the parking garage for $1,950,000. The sale eliminates prior obligations for conveyance payments to the City of South Bend. Under the terms of the sale, existing operation and maintenance agreements remain in place ensuring availability of parking for 1st Source customers and employees.

1st Source also has agreed to expend $5,400,000 on building and other infrastructure improvements to facilities and systems it owns or leases within the City of South Bend and to secure $375,000 for atrium improvements.
