         13.      Except as amended hereby the Lease remains unamended and in
full force and effect and is hereby ratified and confirmed.

         14.      For any of the Spaces on the 4th Floor, if such Space is or
will become available prior to the commencement date set forth herein for it,
then Landlord shall notify Tenant of such availability, and Tenant may set the
commencement date prior to the original commencement date, but not before such
Space is actually available. Tenant or Landlord shall provide reasonable written
notice of any such change. Minimum base rent payment and tax-escalation payment
for any such early occupancy shall be at the per square foot, per annum rate for
Space leased hereunder in the Fourth Floor Premises at the time of Tenant's

Lease. Any other provision herein notwithstanding, the rent payment and real
estate tax escalation payment for each of the Spaces in Fourth Floor Premises

earlier of the date Tenant occupies such Space for the operation of its business
or the date of substantial completion of Landlord's work on such Space under
Paragraph 8 above.

         15.      If, at the time set for the commencement of a lease of a Space

any part of such Space exists ("Overlapping Space"), then the preexisting lease
for such Overlapping Space, but only to the extent of such Overlapping Space,
shall terminate upon Tenant's vacating such Overlapping Space for Landlord to
perform Landlord's renovations therein under this Fourth Amendment; and base
rent payment and the tax escalation payment for such Overlapping Space under any
such preexisting lease shall be pro rated to end as of the date that Tenant
vacates such Overlapping Space.
