of premium or penalty,  to repay in whole or in part the unpaid  balance of this

Florida.  The exclusive  venue for any litigation in connection  with or arising
out of this Note  shall be Palm  Beach  County,  Florida,  and the Maker  hereby
consents and submits to the jurisdiction of the state and federal courts sitting
