Fair Market Rent In the event that it becomes necessary to determine the Fair Market Rent of any Facility for any purpose of this Master Lease, and the parties cannot agree among themselves on such Fair Market Rent within twenty (20) days after the first request made by one of the parties to do so, then either party may notify the other of a person selected to act as appraiser (such person, and each other person selected as provided herein, an “Appraiser”) on its behalf. Within fifteen (15) days after receipt of any such Notice, the other party shall by notice to the first party appoint a second person as Appraiser on its behalf. The Appraisers thus appointed, each of whom must be a member of The Appraisal Institute/American Institute of Real Estate Appraisers (or any successor organization thereto, or, if no such organization exists, a similarly nationally recognized real estate appraisal organization) with at least ten (10) years of experience appraising properties similar to the Facilities, shall, within forty-five (45) days after the date of the notice appointing the first appraiser, proceed to appraise the applicable Facility to determine the Fair Market Rent thereof as of the relevant date; provided, that if one Appraiser shall have been so appointed, or if two Appraisers shall have been so appointed but only one such Appraiser shall have made such determination within fifty (50) days after the making of the initial appointment, then the determination of such Appraiser shall be final and binding upon the parties. If two (2) Appraisers shall have been appointed and shall have made their determinations within the respective requisite periods set forth above and if the difference between the amounts so determined shall not exceed ten percent (10%) of the lesser of such amounts, then the Fair Market Rent shall be an amount equal to fifty percent (50%) of the sum of the amounts so determined. If the difference between the amounts so determined shall exceed ten percent (10%) of the lesser of such amounts, either party may request the appointment of Experts pursuant to Article XXXIV.
Option Rent The annual Rent payable by Tenant during the Option Term (the “Option Rent”) shall be equal to the “Fair Rental Value,” as that term is defined below, for the Premises as of the commencement date of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to the annual rent per rentable square foot (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, with a comparable level of improvements (excluding any property that Tenant would be allowed to remove from the Premises at the termination of the Lease), for a comparable lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2, below (transactions satisfying the foregoing criteria shall be known as the “Comparable Transactions”), taking into consideration the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same can be utilized by a general office/lab user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however, that in calculating the Fair Rental Value, no consideration shall be given to the fact that Landlord is or is not required to pay a real estate brokerage commission in connection with Tenant’s exercise of its right to extend the Lease Term, or the fact that landlords are or are not paying real estate brokerage commissions in connection with such comparable space. The Concessions shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant. The term “Comparable Buildings” shall mean the Building and those other life sciences buildings which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation of to the building), quality of construction, level of services and amenities, size and appearance, and are located in South San Francisco, California and the surrounding commercial area.
Base Rent Lessee shall pay Base Rent and other rent or charges, as the same may be adjusted from time to time, to Lessor in lawful money of the United States, without offset or deduction, on or before the day on which it is due under the terms of this Lease. Base Rent and all other rent and charges for any period during the term hereof which is for less than one full month shall be prorated based upon the actual number of days of the month involved. Payment of Base Rent and other charges shall be made to Lessor at its address stated herein or to such other persons or at such other addresses as Lessor may from time to time designate in writing to Lessee.
Minimum Rent The defined term “Minimum Rent” set forth in Section 1.66 of the Lease is deleted in its entirety and replaced with the following:
Additional Rent Beginning with the commencement date of the term of this Lease, Tenant shall pay to Landlord in addition to the Basic Rent and as Additional Rent the following: (a) Tenant's proportionate share of all Taxes relating to the Complex as set forth in Paragraph 12, and (b) Tenant's proportionate share of all insurance premiums relating to the Complex, as set forth in Paragraph 15, and (c) Tenant's proportionate share of expenses for the operation, management, maintenance and repair of the Building (including common areas of the Building) and Common Areas of the Complex in which the Premises are located as set forth in Paragraph 7, and (d) All charges, costs and expenses, which Tenant is required to pay hereunder, together with all interest and penalties, costs and expenses including attorneys' fees and legal expenses, that may accrue thereto in the event of Tenant's failure to pay such amounts, and all damages, reasonable costs and expenses which Landlord may incur by reason of default of Tenant or failure on Tenant's part to comply with the terms of this Lease. In the event of nonpayment by Tenant of Additional Rent Landlord shall have all the rights and remedies with respect thereto as Landlord has for nonpayment of rent. The Additional Rent due hereunder shall be paid to Landlord or Landlord's agent (i) within five days for taxes and insurance and within thirty days for all other Additional Rent items after presentation of invoice from Landlord or Landlord's agent setting forth such Additional Rent and/or (ii) at the option of Landlord, Tenant shall pay to Landlord monthly, in advance, Tenant's prorata share of an amount estimated by Landlord to be Landlord's approximate average monthly expenditure for such Additional Rent items, which estimated amount shall be reconciled within 120 days of the end of each calendar year or more frequently if Landlord so elects to do so at Landlord's sole and absolute discretion, as compared to Landlord's actual expenditure for said Additional Rent items, with Tenant paying to Landlord, upon demand, any amount of actual expenses expended by Landlord in excess of said estimated amount, or Landlord crediting to Tenant (providing Tenant is not in default in the performance of any of the terms, covenants and conditions of this Lease) any amount of estimated payments made by Tenant in excess of Landlord's actual expenditures for said Additional Rent items. The respective obligations of Landlord and Tenant under this paragraph shall survive the expiration or other termination of the term of this Lease, and if the term hereof shall expire or shall otherwise terminate on a day other than the last day of a calendar year, the actual Additional Rent incurred for the calendar year in which the term hereof expires or otherwise terminates shall be determined and settled on the basis of the statement of actual Additional Rent for such calendar year and shall be prorated in the proportion which the number of days in such calendar year preceding such expiration or termination bears to 365. See Paragraph 54
