Subtenant acknowledges that Subtenant’s late payment of Rent will cause Sublandlord to incur costs not contemplated by this Sublease, the exact amount of such costs being difficult and impractical to fix. Such other costs include, without limitation, processing, administrative and accounting charges and late charges that may be imposed on Sublandlord.  Accordingly, if Subtenant fails to pay any Rent within three (3) days of the date when due, Subtenant shall pay a late charge and interest thereon equal to 5% of the delinquent installment of Rent.   Sublandlord and Subtenant agree that this late charge represents a fair and reasonable estimate of the costs that Sublandlord will incur due to Subtenant’s late payment of Rent.  Sublandlord’s acceptance of a late charge will not constitute a waiver of Subtenant’s default with respect to the delinquent amount or prevent Sublandlord from exercising any of the other rights and remedies available to Sublandlord under this Sublease or under applicable law.  No endorsement or statement on a check or letter accompanying a check or payment shall be considered an accord and satisfaction of past due Rent.  Subtenant’s covenant to pay Rent is independent of every other covenant in this Sublease.
