Pursuant to the Underwriting Agreement, the Company also granted the Underwriters a 30-day option to purchase up to an additional $6.0 million aggregate principal amount of the Notes to cover over-allotments, if any.

The Notes are fully and unconditionally guaranteed (the “Guarantee”) by the Guarantor.

The Company may redeem the Notes in whole or in part at any time or from time to time at the Company’s option on or after June 1, 2027, upon not less than 30 days’ nor more than 60 days’ notice to holders prior to the redemption date, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, as described in greater detail in the Indenture.

The occurrence of an Event of Default (as defined in the Indenture) may, subject to certain conditions set forth in the Indenture, lead to the principal amount of, premium, if any, and accrued and unpaid interest on all of the outstanding Notes to be due and payable immediately.
