 14. No Waiver. No failure on the part of Lender to exercise,
and no delay in exercising any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Lender of any right, remedy or power hereunder preclude any other or future exercise of any other right,
remedy or power. Each and every right, remedy or power hereby granted to Lender or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by Lender from time to time.

of the State of New York or the United States District Court for the Southern District of New York, in each case, located in New York County, New York. Borrower consents to the exclusive jurisdiction and venue of the foregoing courts and consents
