terms of the Lease Agreement; and (b) Lessor shall use commercially reasonable
efforts to investigate the status of the roof and if, as a result of such

Original Lease, Lessor at Lessor’s expense shall make the repairs at its
expense, but should it be determined that Lessee has not fulfilled its
obligations under the Lease Agreement, then Lessee at Lessee’s expense shall
bear the cost of the repairs, as required under the Lease Agreement.

5. New Options to Renew. Lessor hereby grants to Lessee two (2) consecutive

the “Original Term” shall mean the Extension Period; (B) references therein, and
