# Texas Ventures Acquisition III upsizes sponsor note to $750K convertible at $10 per unit

## Summary
- Amended and restated convertible unsecured note dated Nov 8, 2026 raises principal to up to $750,000 from $250,000 after Yorkville Acquisition Sponsor II agreed to lend up to $500,000 more.
- Note bears no interest; principal is payable on the earlier of consummation of the initial business combination or the effective date of the company's winding up.
- Sponsor may convert at $10.00 per unit into up to 75,000 New Units (one Class A share plus one-half warrant at $11.50 strike), exercisable 30 days after the business combination.
- Sponsor waives claims against the IPO trust account, but the note is repayable from trust proceeds released at closing; principal is prepayable at the company's election.
- Issued under Section 4(a)(2); amends and replaces the $250,000 note dated Sept 30, 2026, signed by CEO/CFO Troy Rillo.
