Sublease will commence on the date tenant chooses to take possession but no

Subtenant upon determination that the Premises have suffered only normal wear
and tear during the term of this Sublease. In the event that Subtenant takes
possession prior to September 16, 2002, Subtenant shall deliver to Tenant at
that time, rent prorated from that date thru September 15, 2002.

         A late charge of six (6%) percent of the Rent shall be incurred if rent
is not paid when due. If Rent is not paid when due and Tenant issues a Notice To

Subtenant shall only tender cash or cahier's check for all future payments. This

addition, Subtenant shall be liable in the sum of $25.00 for each check that is
returned to Tenant because the check has been dishonored.

with the provisions of the Master Lease and this Sublease, and for no other
purpose.

extent that they relate to the Subleased Premises and to the extent that they
are not inconsistent with the terms of this Sublease are made a part of and
incorporated into this Sublease as if recited in full in this Sublease.

         The rights and obligations of the Landlord and the Tenant under the
Master Lease will be deemed the rights and obligations of Tenant and Subtenant,
respectively, under this Sublease, and will inure to the benefit of, and be

Sublease only, in the event of a conflict between the terms of the Master Lease
and the terms of this Sublease, the terms of this Sublease will control.

provided for in the Sublease without any abatement, deduction or setoff. Except

bound by, all of the covenants, agreements,
