These costs shall include any expenses incurred by the Purchaser in any bankruptcy, reorganization, or other insolvency proceeding.

In no event shall the interest rate charged or received hereunder at any time exceed the maximum interest rate permitted under applicable law. Payments of interest received by Purchaser hereunder which would otherwise cause the interest rate hereunder to exceed such maximum interest rate shall, to the extent of such excess, be deemed to be (and deemed to have been contracted as being) prepayments of principal and applied as such.
