YOU MAY LATER CANCEL ANY INSURANCE PURCHASED BY US, BUT ONLY AFTER PROVIDING EVIDENCE THAT YOU HAVE OBTAINED INSURANCE AS REQUIRED BY OUR AGREEMENT. IF WE PURCHASE INSURANCE FOR THE COLLATERAL, YOU WILL BE RESPONSIBLE FOR THE COSTS OF THAT INSURANCE, INCLUDING THE INSURANCE PREMIUM, INTEREST AND ANY OTHER CHARGES WE MAY IMPOSE IN CONNECTION WITH THE PLACEMENT OF THE INSURANCE, UNTIL THE EFFECTIVE DATE OF THE CANCELLATION OR EXPIRATION OF THE INSURANCE.
