Additional Rent. Subtenant shall pay to Sublandlord its pro rata share (“Pro-Rata Share”) of all “Direct Expenses” (as defined in [Section 4.2.2] of the Master Lease) and costs of utilities under [Section 6.2] of the Master Lease, as incorporated herein, and all amounts other than Base Rent required to be paid by Sublandlord under the Master Lease to perform maintenance or provide utilities with respect to the Subleased Premises and the Shared Area (in each case as if Master Landlord provided the same; including being subject to the terms of [Section 4.2.4] of the Master Lease), as and when such amounts are due under the Master Lease, as incorporated herein. For purposes of this Sublease, Subtenant’s Pro Rata Share is deemed to be 13.97% with respect to the Building, which is equal to 100% of the rentable square feet of the Subleased Premises plus 25% of the rentable square feet of the Shared Area, divided by the square footage of the Building, and 29.23% with respect to the Premises. Sublandlord shall promptly forward to Subtenant all Estimate Statements, Statements, invoices and backup documentation received from Master Landlord regarding “Tenant’s Share” of Direct Expenses under the Master Lease. Subtenant shall also pay to Sublandlord, within thirty (30) days of request by Sublandlord, the entire cost of such amounts to the extent due to the misuse or excess use or negligence, willful misconduct or violation of this Sublease by Subtenant or any of its agents, employees or contractors. In addition, Subtenant shall pay to Sublandlord, within thirty (30) days of request by Sublandlord, the entire cost of Sublandlord’s cost of performing any repairs or maintenance or providing other services to the Subleased Premise or Shared Area specifically requested by Subtenant. All monetary obligations of Subtenant to Sublandlord under this Sublease (other than Base Rent) shall be deemed “Additional Rent.” Base Rent and Additional Rent shall be referred to collectively as “Rent”. Subtenant shall be entitled to its Pro-Rata Share of all credits, if any, given by Master Landlord to Sublandlord for Sublandlord’s overpayment of such amounts, and shall not be required to pay any gross receipts tax on rent payable under the Master Lease.

Additional Rent. Except as otherwise provided in this Lease, any additional rent or other sum owed by Tenant to Landlord hereunder, and any cost, expense, damage or liability incurred by Landlord for which Tenant is liable hereunder, shall be considered additional rent payable pursuant to this Lease to be paid by Tenant no later than thirty (30) days after the date Landlord notifies Tenant of the amount thereof.

Subject to the provisions of this Paragraph 3, Tenant shall pay during the Term as rent for the Premises the sums specified in the Basic Lease Information (as increased from time to time as provided in the Basic Lease Information or as may otherwise be provided in this Lease) (the “Base Rent”). Base Rent shall be payable in consecutive monthly installments, in advance, without prior notice, demand, deduction or offset, commencing on the Term Commencement Date and continuing on the first day of each calendar month thereafter, except that the first full monthly installment of Base Rent shall be payable upon Tenant’s execution of this Lease. If the Term Commencement Date is not the first day of a calendar month, then the Base Rent for the Partial Lease Month shall be prorated based on the actual number of days of that month, and shall be payable on the first day of the calendar month following the Term Commencement Date. Any and all payments which are due, or may become due and owing at any time in the future under the Lease, including but not limited to Rent, Additional Rent, CAM, Expense, Security Deposit, reimbursements, and fines shall be paid only in lawful currency of the United States of America (e.g. USD).

Southwestern shall use Southwestern’s year-end audited financial statements in determining the extent to which the Performance Targets were achieved during the Performance Period for each Performance Measure and shall certify in writing whether and the extent to which Performance Targets under the Performance Measures for the Performance Period have been met.

No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Base Rent or any Additional Rent will be other than on account of the earliest stipulated Base Rent and Additional Rent, nor will any endorsement or statement on any check or letter accompanying a check for payment of any Base Rent or Additional Rent be an accord and satisfaction. Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or to pursue any other remedy provided in this Lease.

Late Payment of Rent. If any installment of Rent, Additional Rent, Subtenant TI Cost Reimbursement, or any other sum due from Subtenant hereunder shall not be received by Sublandlord within five (5) days after such amount shall be due, then, without any requirement for notice to Subtenant, Subtenant shall pay to Sublandlord a late charge equal to five percent (5%) of such overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Sublandlord will incur by reason of late payment by Subtenant.
