Notwithstanding Section 20 above, in the event the entire balance of rent due under this lease becomes due and payable as liquidated damages, said amount shall be discounted to its net present value as of the date of LESSOR’S notice of default, using the published prime rate then in effect. Furthermore, LESSEE’S covenants under this lease shall be independent of LESSOR’S covenants, and LESSOR’S failure to perform any of its covenants under this lease, including a covenant constituting a significant inducement to LESSEE to enter into this lease, shall not excuse the payment of rent or any other charges by LESSEE or allow LESSEE to terminate this lease.
