If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Lender, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Lender in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Lender if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Lender may determine.
