On August 1, 2025, the Company and the Purchasers executed the Note Purchase Agreement which authorized the sale and purchase of $200 million of aggregate principal amount of unsecured senior notes (the “Senior Notes”). $150 million of the Senior Notes closed and funded on August 1, 2025 and $50 million is expected to close and fund on September 15, 2025. The Senior Notes consist of (a) $60 million aggregate principal amount of 4.88% Series 2025-A Senior Notes due August 1, 2028 (the "Series 2025-A Notes"), (b) $90 million aggregate principal amount of 5.16% Series 2025-B Senior Notes due August 1, 2031 (the "Series 2025-B Notes"), and $50 million aggregate principal amount of 5.02% Series 2025-C Senior Notes due September 15, 2030 (the "Series 2025-C Notes"). The following is a summary of the material terms to which the Senior Notes will be subject.

a.Maturity Dates: The outstanding principal balance of the Senior Notes will be due and payable on the Maturity Dates (as defined in the first paragraph of each note) and set forth above.

The Senior Notes may be accelerated by the occurrence of certain payment defaults as set forth in the Note Purchase Agreement.

The Note Purchase Agreement includes customary events of default to which the Senior Notes are subject, including payment default on the Senior Notes and certain other indebtedness and obligations of the Company and bankruptcy, insolvency or similar events.
