II, a Delaware corporation and blank check company (the “Maker”), promises to pay to the order of Longview Investors II LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of Three Million Dollars ($3,000,000) or such lesser amount as shall have been advanced by Payee to Maker in lawful money of the United States of America, on the terms and conditions described below.
