expense with reasonable promptness. In the event of termination of this Lease,

paid to the date of the fire or other casualty, unless the premises shall be
tenantable and reasonably accessible in which case rent shall be payable to the
date of the Lease termination. If the premises are untenantable or are not
readily accessible and this Lease is not terminated, rent shall abate on a per
diem basis from the date of the fire or other casualty until the premises are
ready for occupancy and reasonably accessible to Lessee. If part of the
premises are untenantable, rent shall be pro-rated on a per diem basis and
apportioned in accordance with the part of the premises usable by Lessee, until
the damaged part is ready for Lessee's occupancy. In all cases, due allowance
shall be made for reasonable delay caused by adjustment of insurance loss,
strikes, labor difficulties or any cause beyond Lessor's reasonable control.

         12.     If, by any action of the public authorities, or any similar
cause or reason not within the scope of the immediately preceding paragraph 11,
the demised premises or any part thereof shall have become untenantable for
Lessee's business as now

conducted, the parties shall have the same options, rights and obligations as
provided in the case of partial destruction by fire, in the immediately
preceding paragraph 11.

         13.     This Lease shall replace a Lease between the Lessor and Lessee
dated March l, 1995, and said March 1, 1995 Lease is terminated and null and
void as of the commencement date of this Lease.

         14.     That the covenants herein contained shall bind the parties
mutually and their respective heirs, personal representatives, successors and
assigns.

         IN WITNESS WHEREOF, the parties have hereunto set their hands and
