any alterations, additions or improvements to any common areas without
Landlord's prior written consent, which consent may be granted or withheld in
Landlord's sole discretion. Any alterations, additions or improvements requested
by Tenant and approved by Landlord shall be performed (i) by Landlord's
contractor or another contractor approved by Landlord, (ii) in a good and
workmanlike manner, and (iii) in accordance with all applicable codes, laws,

period of one (1) year (the "Renewal Term") by giving written notice to Landlord

Rental shall be calculated at the annual rate of $20.50 per square foot of net
rentable area.

                  c)       If Tenant shall fail to exercise its option for the
Renewal Term, or if all conditions set forth above are not entirely satisfied,
the Lease shall expire at the expiration of the Extension Term and Tenant shall
have no further right thereafter to renew the Lease or to require any interest
whatsoever in the Leased Premises.

                  d) This option to renew is not transferable and shall be

negotiations of this Fourth Amendment and each party shall indemnify and hold

expense in the event of the inaccuracy of such representations and warranty.
