Taxes and Operating Expenses as described in Article 5 of the Lease shall be

       6. Section 6.02 of the Lease is hereby deleted and the following
substituted therefor:

       6.02. Landlord represents that there is no existing mortgage on the Land
and Building. In the event the Land or Building is encumbered by a mortgage lien
in the future, as a condition of Tenant’s subordination thereto, Landlord shall
obtain from such future mortgagee a Non-Disturbance Agreement in favor of Tenant
utilizing such mortgagee’s standard and customary form; provided, however, such
Non-Disturbance Agreement must (a) contain an acknowledgement and consent by the
mortgagee to the terms and conditions of this Lease, and (b) must generally
provide that so long as Tenant is not in default of its obligations under this
Lease, then its use and enjoyment of the Demised Premises shall not be disturbed
and that Tenant will not be named in or joined in any action or proceeding to
foreclose any such mortgage. If such Non-Disturbance Agreement contains usual
and customary institutional lender and tenant provisions and further provides
for an opportunity for the mortgagee to cure any Landlord defaults and other
reasonable lender requirements, then such Non-Disturbance Agreement shall be
deemed in conformance with the provisions hereof. If Tenant fails to reasonably
accept such Non-Disturbance Agreement, it shall be considered that Landlord has
satisfied any requirement respecting the future mortgagee and this Lease shall
be subordinate to the lien of the Mortgage. If Landlord is unable to obtain from
the Lender the Non-Disturbance Agreement as described in this Section 6.02, then
this Lease shall not be deemed subordinate to the lien of such future mortgagee.
Landlord shall facilitate the communication of requested changes to any form
from Tenant to the future mortgagee so as to ensure that Tenant’s changes and
comments are made known to the future mortgagee.

       7. The following Section is added to Article 8 (Assignment, Mortgaging,
Subletting) of the Lease:

       8.09. Tenant agrees that in connection with each separate request for a
Landlord’s consent to a subletting or assignment (including the review of a
statutory or other name change), Tenant shall pay to Landlord the sum of $500.00
representing a reasonable compensation to Landlord for the administration costs
of evaluating and responding to the request.

       8. The “monthly fixed rent payable during the last month of the term”as
referred to in Section 40.01 of the Lease shall be deemed to refer to the
monthly fixed rent set forth in this First Amendment.

       9. Article 42 of the Lease, Option to Renew, is hereby declared to be
null and void and of no further force and effect.

       10. Landlord and Tenant mutually covenant, warrant, and represent to each
other that there was no broker except The Garibaldi Group, L.L.C. (“Broker”)
instrumental in consummating this First Amendment to Lease and that no
conversations or negotiations were had with any broker except Broker concerning
the renewal of the Lease. Landlord and Tenant agree to hold the other harmless
against any claims for a brokerage commission arising out of any conversations
or negotiations had by it with any broker except Broker. Landlord agrees to pay
Broker pursuant to a separate agreement.

       11. Landlord represents that it presently holds a $400,000.00 letter of
credit pursuant to Article 35 (Security Deposit) of the Lease. Section 35.02 of
the Lease is hereby deleted.

       12. Except as modified herein, all of the terms, covenants and conditions
set forth in the Lease remain in full force and effect

          IN WITNESS WHEREOF, the parties hereto have hereunto set their hands
and seals the day and year first above written.
