Tenant shall have until six (6) months following the Term Commencement Date (the “TI Deadline”), to submit Fund Requests (as defined in the Work Letter) to Landlord for disbursement of the unused portion of the TI Allowance, after which date Landlord’s obligation to fund any such costs for which Tenant has not submitted a Fund Request to Landlord shall expire. Base Rent shall be increased to include the amount of the Additional TI Allowance disbursed by Landlord in accordance with this Lease amortized over the portion of the initial Term occurring after the expiration of the Abatement Period (as defined below) at a rate of eight percent (8.00%) annually. The amount by which Base Rent shall be increased shall be determined as of the Term Commencement Date and Base Rent shall be increased accordingly and the payments of such increased Base Rent shall commence after expiration of the Abatement Period. If such determination of the increase in Base Rent as of the Term Commencement Date does not reflect use by Tenant of all of the Additional TI Allowance, then it shall be determined again as of the TI Deadline, with Tenant paying (on the next succeeding day that Base Rent is due under this Lease (the “TI True-Up Date”)) any underpayment of the further adjusted Base Rent for the period beginning on the day after the Abatement Period expires and ending on the TI True-Up Date. For purposes of clarification, the annual upward adjustments of Base Rent described in Section 2.3 shall apply to any increase in Base Rent arising from any disbursement of the Additional TI Allowance. Landlord shall not be obligated to expend any portion of the Additional TI Allowance unless and until Landlord shall have received from Tenant a letter in the form attached as [Exhibit D] hereto executed by an authorized officer of Tenant.

Base Rent is subject to an annual upward adjustment of three percent (3%) of the then-current Base Rent, with the first such adjustment becoming effective commencing on the first (1st) annual anniversary of the Term Commencement Date, and subsequent adjustments becoming effective on every successive annual anniversary of the Term Commencement Date during the Term. The foregoing table reflects such annual upward adjustments of the Base Rent. Base Rent is also subject to adjustment arising from any disbursement of the Additional TI Allowance as set forth in Section 4.4 below and subject to abatement in accordance with Article 8 below.

Commencing on the Term Commencement Date, Tenant shall pay to Landlord the sums set forth in Section 2.3 as Base Rent for the Premises, subject to the abatement of Base Rent to the extent set forth in Section 8 below. Base Rent shall be paid in equal monthly installments as set forth in Section 2.3, each in advance on the first day of each and every calendar month during the Term. For the avoidance of doubt, Tenant’s payment of Base Rent for the first (1st) month of the Term shall be delivered to Landlord on the Term Commencement Date.

Notwithstanding anything in the above Section 4 to the contrary, applicable monthly Base Rent only for the Expansion Premises shall be abated for the months of August, 2014 and August, 2015 (the “Expansion Space Rent Abatement Period”); provided, however, all other payments required to be paid by Tenant to Landlord pursuant to the Lease for the Premises and the Expansion Space shall remain due and payable during the Expansion Space Rent Abatement Period. If at any time during the initial Term Landlord terminates this Lease as a result of an Event of Default of a monetary nature hereunder, the abatement of Base Rent for the Expansion Space provided for herein shall immediately become void, and Tenant shall promptly pay to Landlord, in addition to all other amounts due to Landlord under the Lease, the full amount of all Base Rent for the Expansion Space herein abated, multiplied by a fraction, the numerator of which is the number of full calendar months remaining in the Term for the Expansion Space as of the date Landlord terminates this Lease as a result of an Event of Default of a monetary nature and the denominator of which is 57.

Base Rent and Additional Rent, as defined in Paragraph 4.B below, with the exception of the initial Base Rent as provided in Paragraph 4.C below, shall be paid on or before the first (1st) day of each month.

Base Rent and Additional Rent shall be paid directly to Sublessor at the applicable address set forth below Sublessor’s signature to this Sublease or such other address as may be designated in writing by Sublessor. Base Rent and Additional Rent for any period during the Term hereof which is for less than one (1) month of the Term shall be a pro rata portion of the monthly installment based on a thirty (30) day month. If an increase in Base Rent becomes effective on a date other than the first day of a calendar month, the Base Rent for that month shall be the sum of the two applicable rates, each prorated for the portion of the month during which the rate is in effect.

The “Property Management Fee” shall equal three percent (3.00%) of Base Rent due from Tenant. Tenant shall pay the Property Management Fee in accordance with Section 9.2 with respect to the entire Term, including any extensions thereof or any holdover periods by Tenant, regardless of whether Tenant is obligated to pay Base Rent, Operating Expenses or any other Rent with respect to any such period or portion thereof. During the Abatement Period (and any period of occupancy prior to the Term as further described in Section 9.5), the Property Management Fee shall be calculated as if Tenant were paying Seventy-Five Thousand Two Hundred Forty and 00/100 Dollars ($75,240.00) per month for Base Rent.
