Financing Lease Obligation Terms On March 31, 1999, the Company completed a $4.5 million financing obligation involving three existing restaurants as part of a sale/leaseback transaction. Under this financing, we are obligated to make monthly payments of $56,627 (which increases 4.04% every two years) for a minimum of 20 years. At the end of the 20 year lease term, we may extend the lease for up to two additional five year terms. We also have the option to purchase the leased restaurants on the 20th anniversary of the lease term and between the first and second five year option terms. The option purchase price is the greater of $4.5 million or the fair market value, as defined in the agreement, of the properties at the time the purchase option is exercised. Based upon our continued involvement in the leased property and its purchase option, the transaction has been accounted for as a financing arrangement. Accordingly, the three existing restaurants are included in property, equipment and leasehold improvements, and are being depreciated over a 20 year term. In addition, as the monthly lease payments are made, the obligation will be reduced by the 20 year amortization table.
