provisions and conditions hereinafter set forth, Authority and Tenant do
hereby covenant and agree, and each for itself does hereby covenant and
agree, as follows:

         SECTION 1. DEFINITIONS. Except as otherwise provided herein, and
unless the context shall clearly require otherwise, all words and terms used
in this Twentieth Supplemental Lease Agreement which are defined in the Lease
Agreement, shall, for all purposes of this Twentieth Supplemental Lease
Agreement, have the respective meanings given to them in the Lease Agreement.

         SECTION 2. GRANTING OF LEASEHOLD. In addition to the lease and
demise to Tenant of the land in the Lease Agreement, the Authority hereby
leases and demises to Tenant, and Tenant hereby takes and hires from
Authority, subject to the provisions and conditions set forth in the Lease

Agreement for the purpose of constructing improvements required for Tenant's
intended use of the land leased hereby, subject however, to Authority's
right-of-entry set forth in Section 21 of the Lease Agreement.

         SECTION 4. RENTAL. In addition and supplemental to the rentals
required to be paid to the Authority pursuant to Section 5 of the Lease
Agreement (including all prior supplemental lease agreements), during the
term of this Twentieth Supplemental Lease Agreement, Tenant shall pay the
Authority in advance on the first business day of each month $5,848.41 in
equal installments beginning December 1, 2000 or date of beneficial occupancy

"Environmental Laws", then the form of Remediation will be determined by the

enforcement jurisdiction over the subject site. Authority will grant to
Tenant a rent credit equal to the reasonable documented costs paid by Tenant
for the Remediation of such "Hazardous Substances" associated with the
centerline intersection of Taxiway November and Taxilane 800.

Supplemental Lease Agreement, shall mean any hazardous or toxic substances,

sections of this Twentieth Supplemental Lease agreement are inserted for
