Upon the occurrence of any Default and the continuance thereof, and upon prior written notice to Undersigned by Bank, interest shall accrue at an annual rate which shall be two percent (2%) above the rate of interest otherwise payable hereunder. At the option of Bank, interest which is not paid when due shall be added to principal. If any of the Liabilities or any portion thereof owing to Bank is not paid in full when due, Bank may, at its option and without notice, withdraw from any account of Undersigned with Bank an amount equal to such overdue amount and to apply such amount to the payment of the overdue Liabilities. All rights or remedies of Bank set forth or otherwise existing are cumulative. Neither any delay or failure by Bank, in exercising any of its options, powers or rights herein, nor any partial or single exercise thereof shall constitute a waiver of the right to exercise the same or any other right at any other time or from time to time thereafter. Bank is not required to resort to any particular security or persons to enforce payment, and Bank is not subject to any marshalling requirements of equities among Undersigned, if more than one, and among it or them.
