of Landlord to perform any alterations, repairs or improvements, except as may be
expressly provided otherwise in this Amendment.




B. Cost of Improvements to Expansion Space. Provided Tenant is not in default,
Tenant shall be entitled to receive an improvement allowance (the “Expansion

Lease shall remain unchanged and in full force and effect.




C. In the case of any inconsistency between the provisions of the Lease and this
Amendment, the provisions of this Amendment shall govern and control.

Landlord in writing.




G. Tenant hereby represents to Landlord that Tenant has dealt with no broker in
connection with this Amendment except Grubb & Ellis | Levy Beffort. Tenant agrees
to indemnify and hold Landlord and the Landlord Related Parties harmless from all
claims of any brokers claiming to have represented Tenant in connection with this
Amendment.




H. The liability of Landlord for Landlord’s obligations under the Lease, as amended
by this Agreement (the “Amended Lease”), shall be limited to Landlord’s interest in
the Building and the land thereunder and Tenant shall not look to any other property
or assets of Landlord or the property or assets of any partner, shareholder,
director, officer, principal, employee or agent, directly and indirectly, of

to perform such obligations; and none of the Parties shall be personally liable for
the performance of Landlord’s obligations under the Amended Lease.



     IN WITNESS WHEREOF, Landlord and Tenant have duly executed this Amendment as of the day and
