If any installment of Rent is not paid promptly on the first of the month or otherwise when due, the unpaid amounts shall bear interest at the Interest Rate specified in Section 4.5 of the Master Lease from the date due to the date of payment.  In addition, Subtenant acknowledges that the late payment of any installment of Rent will cause Sublandlord to incur certain costs and expenses not contemplated under this Sublease, the exact amount of which are extremely difficult or impractical to fix.  These costs and expenses will include, without limitation, administrative and collection costs and processing and accounting expenses.  Therefore, if any installment of rent is not received by Sublandlord from Subtenant when due with respect to Base Rent, or within three (3) business days after notice such installment is due with respect to components of rent other than Base Rent, Subtenant shall immediately pay to Sublandlord a charge for administration collection and accounting expenses equal to five percent (5%) of the amount of such delinquent amounts due in addition to the installment of Rent then owing with interest at rate specified above, regardless of whether or not a notice of default or notice of termination has been given by Sublandlord.  Notwithstanding the foregoing, Subtenant will be entitled to notice and a three (3) business day cure period before a late fee is assessed for the first late payment of Base Rent in any calendar year only.  Sublandlord and Subtenant agree that the late payment charge represents a reasonable estimate of Sublandlord’s costs and expenses and is fair compensation to Sublandlord for its loss suffered by Subtenant’s nonpayment of any amounts when due and payable pursuant to this Sublease.  This provision shall not relieve Subtenant from payment of Rent at the time and in the manner herein specified.
