Each of the Guarantors agrees that its guarantee hereunder shall continue to be effective or be reinstated, as the case may be, if at any time pay ment, or any part thereof, of any Obligation, is rescinded, invalidated or must otherwise be re stored by the Administrative Agent or any other Secured Party upon the bankruptcy or reorgani zation of any Guarantee Party or otherwise.
