• Drawdowns can be requested up to USD 100,000, with funding due within five business days of each request.
• Note bears no interest, with principal due at consummation of initial business combination; non-payment at that point triggers an event of default that can accelerate repayment.
• If no business combination is completed, repayment is limited to funds available outside trust account tied to initial public offering.
