Chiron Real Estate LP (the Operating Partnership) and Chiron Real Estate Inc. (the Parent) entered into a Master Note and Guaranty Agreement (the Agreement) with NYL Investors LLC and its affiliates (the Purchasers) on March 2, 2026. The Agreement establishes an uncommitted senior note facility, allowing the Operating Partnership to issue senior unsecured promissory notes (the Notes) up to an aggregate outstanding principal amount of $150.0 million. The facility is uncommitted, meaning New York Life and the Purchasers are not obligated to purchase any Notes, and each purchase is subject to their sole discretion and customary conditions. Notes may be issued during a period ending on the earliest of March 2, 2029 (third anniversary), termination by either party, or termination following certain events of default. Each series of Notes will have a stated maturity of no more than ten years from the date of issuance, with interest rates determined at issuance based on spreads over U.S. Treasury securities, payable quarterly or semi-annually. The minimum principal amount for any single issuance of Notes is $10.0 million. The Notes are senior unsecured obligations of the Operating Partnership and rank pari passu with its other senior unsecured indebtedness. The Parent unconditionally and irrevocably guarantees the obligations of the Issuer under the Notes and the Agreement, and Subsidiary Guarantors will also provide guarantees. An 'Increased Interest Event' will occur if the Coupon Adjustment Leverage Ratio is greater than or equal to 6.50 to 1.00 as of December 31, 2026, leading to a 0.65% per annum increase in the interest rate on outstanding Notes from January 1, 2027, until the ratio falls below 6.50 to 1.00 for two consecutive fiscal quarters.
