Irrespective of the foregoing, the Commencement Date shall not occur prior to November 15, 1994, unless Tenant occupies the Demised Premises for the conduct of its business. Landlord shall use its good faith efforts to cause the Commencement Date for the fifth, sixth and ninth floors of the Demised Premisesto occur on November 15, 1994, or as soon thereafter as reasonably practical subject to events or circumstances beyond the reasonable control of Landlord. Anything to the contrary contained herein notwithstanding, with respect to the fifth, sixth and ninth floors of the Demised Premises, 2 (i) on or before June 30, 1994, Tenant shall provide Landlord with final, approved pricing documents related to the upfitting of the Demised Premises (including, without limitation, space plans showing electrical outlets, telephone jacks, final wall locations and finish parameters); and (ii) on or before July 31, 1994, Tenant shall provide Landlord with final, approved plans and specifications and permit drawings released for construction related to the upfitting of the Demised Premises.

During each Option Period(s), the Annual Minimum Rent for the Demised Premises shall be as specified in Schedule I. For purposes of this Lease, the term "Market Rate" or "Market" shall mean the annual minimum rent established by Landlord to reflect Landlord's estimate of the annual minimum rent which could reasonably be expected from a third party if the Demised Premises were released for the Option Period; however, the annual minimum rent so established shall not exceed the annual minimum rent then generally being quoted by Landlord to prospective tenants for comparable tenant space in the Building, and if no comparable tenant space is then being leased in the Building, the annual minimum rent so established shall not exceed the annual minimum rent then being quoted by landlords for new tenants for comparable tenant space in first-class, high-rise office buildings in the vicinity of the Building(in each case as adjusted to allow for a Base Amount and Tax Base Amount equivalent to that specified in Schedule D. For purposes of the foregoing definition, all references as to the quotation of annual minimum rent shall mean the rent quoted for a term comparable to the Option Period to the fullest extent possible. In the event, Tenant exercises its option to extend the term of this Lease pursuant to this Section 4.07, at the request of Tenant, Landlord, at its sole cost, shall cause the Demised Premises to be recarpeted and painted and new wallcoverings to be installed with all such reupfittings to be of the substantially same standard and quality as the original upfitting of the Demised Premises pursuant to Exhibit C attached hereto.

If the base for the Index is changed so that 1982-84 prices &re no longer taken as representing 100, an appropriate adjustment will be applied to the published indices so as to rate them to the aforesaid base in which 1982-84 prices are taken as representing 100. In the event the Index is discontinued, such other substantially similar government index or publication as chosen by Landlord and Tenant for a reasonable replacement shall be used for such adjustment. Landlord shall not be prohibited from leasing space or providing other options for space on the fourth floor of the Building for periods which conflict with Tenant's expansion option. Notwithstanding anything mentioned above, the actual delivery date of the Option Space may vary up to one hundred eighty (180) days based upon obligations to the existing tenant(s). Additionally, Tenant will act reasonably and in good faith to phase its occupancy requirements so as to promote orderly vacating of the Option Space.

Nothing in this Lease shall require Landlord to give any notice prior to the commencement of any summary dispossess proceeding for nonpayment of Annual Minimum Rent and additional rent or a plenary action for the recovery of Annual Minimum Rent and additional rent on account of any default in the payment of any rent payable under this Lease. 20.04.
