Pursuant to Paragraph (c) of the Basic Lease Information, Landlord recognizes that the guaranteed maximum price under the Construction Contract has increased by a total amount equal to $903,391.00 and has agreed to advance the full $500,000 contingency outlined in the Project Budget and advance an additional $403,391.00 to cover the increase. Therefore, the annual Fixed Rent will increase by a total of $108,924.00 ($500,000 *11.7% plus $403,391 *12.5%) for a new annual Fixed Rent of $2,374,339.00. Beginning in the month of January 2001 and every month thereafter until September of 2002, the monthly payments shall be in the amount of $197,862.00.

If, upon Final Completion of the Improvements, not all of the funds advanced have been used, then the Fixed Rent will be decreased as outlined in Paragraph (c) and confirmed in a second supplement to the Lease.
