If QuietPower requests Thacher to obtain financing for the Purchase Price to be paid by QuietPower in an Acquisition, a separate and additional fee normal and customary for obtaining such financing will be negotiated at that time and will be paid by QuietPower to Thacher upon closing of the financing. Notwithstanding anything to the contrary herein, QuietPower shall not be liable for any Transaction Fee hereunder except in accordance with the above, regardless of the cause of or reasons for the inability or failure to consummate any Acquisition within the time parameters set forth above.
