Premises was modified, effective September 1, 2006, to 115,009 rentable square feet (RSF); and

WHEREAS,the parties have discovered the following mutual mistakes made in the terms set forth in said Fifth Amendment, to-wit:

| | 1. | The total RSF for the Leased Premises effective September 1, 2006 was erroneously identified as 115,009 RSF when the Leased Premises actually will consist of 114,782 RSF as of September 1, 2006.                                                                                                                                                              
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | 2. | The parties failed to identify that the Lower Level Building Equipment Room consisting of 1,032 useable square feet (USF) and the East center staircase containing 185 USF will become Building Common Areas rather than
part of the Leased Premises should Lessee exercise its Option to Give-Back Space as set forth in Article 4 of said Fifth Amendment,
