Item 1.01 Entry into a Material Definitive Agreement

On October 14, 2009, we entered into a discounted payoff agreement with DB Realty Mezzanine Investment Fund II, LLC and DB Realty Mezzanine Parallel Fund II, LLC, holders of the existing mezzanine debt on Two Commerce Square. Under this agreement, we have agreed to pay off the two mezzanine loans, with a principal amount of approximately $36.1 million, for a discounted amount of $25.0 million on or before November 30, 2009 (subject to an extension right of up to 30 days). We have deposited $6.0 million with the holders of the loans under the agreement, which deposit will be credited against the payoff amount on closing. If we exercise the 30 day extension right, the deposit will be increased by an additional $7.0 million.

On October 10, 2009, we entered into a modification agreement with Wells Fargo Bank, holder of the existing mortgage loan on Campus El Segundo. The loan has been extended, without any principal payment to the lender, so that it matures on July 31, 2011, and has three one-year extension options at our election subject to us complying with certain loan covenants. The lender has the option to require payment of $2.5 million at the time of each extension. The interest rate on the loan has been increased to LIBOR plus 3.75% per annum. As of October 15, 2009, the balance of the loan was $17.0 million. We have guaranteed 100% of the principal, interest and any other sum payable under this loan.

On October 13, 2009, we entered into a modification agreement with Wells Fargo Bank, holder of the existing construction loan on Four Points Centre. The Four Points Centre construction loan in the amount of $29.7 million originally was scheduled to mature in June 2010. We have entered into an agreement with the lender to extend this loan to July 31, 2012 with two one-year extension options at our election subject to certain conditions. The first extension option is subject to a 75% loan to value test and a minimum debt yield, among other things. The second extension option is subject to a 75% loan to value test, executed leases representing at least 90% of the net rentable area, and a minimum debt yield, among other things. As of January 31, 2011, if the Four Points office buildings are not at least 65% leased on terms consistent with the appraisal proforma, we must pre-fund 18 months of interest into a restricted cash account with the lender; if the buildings are less than 35% leased at the time, we will also have to pay $2.0 million as a principal reduction of the loan. We have guaranteed the completion of construction and have completed the core and shell of this property. Furthermore, we have guaranteed 46.5% of the principal, interest and any other sum payable under this loan; this guaranty is currently limited to a maximum of $13.8 million and 100% of required principal paydowns. Upon the occurrence of certain events our maximum liability as guarantor will be reduced to 31.5% of all sums payable under this loan, and upon the occurrence of further events our maximum liability as guarantor will be reduced to 25% of all sums payable under this loan. We have agreed to certain financial covenants on this loan as the guarantor, including a net worth covenant of $225.0 million and a minimum unrestricted cash covenant of $10.0 million. We have also agreed to provide additional collateral of approximately 62.4 acres of fully entitled un-improved land, which is immediately adjacent to our Four Points Centre office buildings located in Austin, Texas. We have also committed to pay down the principal amount of the loan in the total amount of $7.8 million which will be paid $3.9 million in November, 2009 and the balance in three equal installments, in January, June and December, 2010. The amounts repaid may not be re-borrowed, but they are available to fund any remaining project costs. The interest rate on the loan has been increased to LIBOR plus 3.50% per annum.
