We note from your disclosure on page 20 that over 14% of your leases expire in 2013. In future Exchange Act periodic reports, to the extent a material amount of your leases expire by the end of the current fiscal year, please discuss the relationship of market rents and expiring rents. Also, please compare rents on new and renewed leases to prior rent, based on effective rent.

Response:
We will incorporate the Staff's Comment in future Exchange Act periodic reports, beginning with our Quarterly report on Form 10-Q for the period ending June 30, 2013.

We will incorporate the Staff's Comment in future Exchange Act periodic reports, beginning with our Quarterly report on Form 10-Q for the period ending June 30, 2013.

the Company is responsible for the adequacy and accuracy of the disclosure in the filing;
