No failure on the part of Buyer to exercise, or delay in exercising, any right or remedy under the Repurchase Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right or remedy thereunder preclude any further exercise thereof or the exercise of any other right.  The rights and remedies in the Repurchase Documents are cumulative and not exclusive of any rights and remedies provided by law.  Application of the Default Rate after an Event of Default shall not be deemed to constitute a waiver of any Event of Default or Buyer’s rights and remedies with respect thereto, or a consent to any extension of time for the payment or performance of any obligation with respect to which the Default Rate is applied.  Except as otherwise expressly provided in the Repurchase Documents, no amendment, waiver or other modification of any provision of the Repurchase Documents shall be effective without the signed agreement of Seller and Buyer.  Any waiver or consent under the Repurchase Documents shall be effective only if it is in writing and only in the specific instance and for the specific purpose for which given.
