<PAGE>   4

equal to 1/12th of Tenant's pro-rata share of Taxes which are payable during any
Lease Year and shall base its estimate on the most recently ascertainable tax
bills, making such adjustments thereto reflect any anticipated increases, as
Lessor may in its reasonable discretion determine. Any fractional month shall be
prorated. Following the issuance by the taxing authorities of first tax bills
payable during any Lease Year, Lessor shall furnish Tenant with a copy of said
tax bill together with a written statement showing Tenant's pro-rata share of
such Taxes and the payments made by Tenant with respect to Lessor's estimate of
Tenant's pro-rata share of the said Taxes during said Lease Year. If Tenant's
pro-rata share of said Taxes exceeds Tenant's payments made pursuant to Lessor's
estimate, Tenant shall pay Lessor the deficiency within ten (10) days after
being invoiced by Lessor; if said payments exceed Tenant's pro-rata share of the
Taxes, Lessor shall credit such excess against the next due payments from Tenant
for Taxes. In the event the commencement date of the term of this Lease during
the first Lease Year and the last Lease Year do not correspond with a tax year,
the number of months within said Lease Years shall be prorated by the number of
lease months to the tax year. As to any tax year, a portion only of which is
contained in the term of this Lease, Tenant's obligation for such pro-rata share
of the actual Taxes shall remain in effect notwithstanding the expiration of
this Lease. Tenant's obligations under this Section shall survive the expiration
of the term of this Lease. Tenant's above initial estimate is $588.00 per month.

SECTION 2.03. Additional Rent

         The Tenant shall pay as additional rent any money required to be paid
pursuant to Sections 2.02, 2.04, 8.01, 10.02, 11.02, 11.04 and 12.01 and all

charges are not paid at the time provided in this Lease, they shall
nevertheless, if not paid when due, be collectible as additional rent with the
next installment of rent thereafter failing due hereunder, but nothing herein
contained shall be deemed to suspend or delay the payment of any amount of money
or charge at the time the same becomes due and payable hereunder, or limit any
other remedy of the Lessor.

SECTION 2.04. Past Due Rent and Additional Rent

         If Tenant shall fail to pay, when the same is due and payable. any rent
or any additional rent, or amount or charges, of the character described in

(5th) day after the due date thereof to the day of payment, at the rate of

a One Hundred Dollar ($100.00) penalty due and payable within seven (7) days
after invoice from Lessor.

boiler and/or casualty insurance policies by reason thereof. The Tenant also

rendered, and the amount thereof shall be deemed to be, and be paid as,
additional rent.

regardless of the cause of such loss or injury, even if it results from some act
or negligence of a party hereto, its agents, servants or employees; provided,
however, that this provision shall be inapplicable if it shall have the effect
of invalidating the insurance coverage of a party hereto. Nothing contained
herein shall relieve Lessor or Tenant of their other obligations described
elsewhere in this Lease.

expenses, losses, actions, suits, claims, judgments, and any other liability
whatsoever in connection with a breach by Tenant of any federal, state or local
environmental protection laws and/or regulations. It is understood by Lessor
that Tenant shall have the right to store within the leased premises minimal
amounts of diesel fuel for purposes of operating the backup generator. Tenant

liable for an interruption or failure in the supply of any such utilities to the
leased premises.

final and binding upon both parties. Each party shall pay the fee and expense of
the appraiser, selected by such party, and, if a third appraiser is selected,
the fee of the third appraiser shall be borne equally between the parties
hereto. Fixed minimum rent during the Option Term shall be paid in monthly

demand therefor and without any deduction or set-off whatsoever. Notwithstanding

minimum rent during the Option Term decrease or be less than the fixed minimum
rent paid during the last Lease Year of the Lease Term.
