Subordinated Notes Payable

On March 13, 2017, the Company completed the public offering and sale of $75.0 million in aggregate principal amount of its 5.75% Fixed-To-Floating Rate Subordinated Notes due 2027 (the “subordinated notes”). The subordinated notes were sold to the public at par pursuant to an underwriting agreement and were issued pursuant to an indenture and a supplemental indenture. The subordinated notes will mature on March 15, 2027 and through March 14, 2022 will bear a fixed rate of interest of 5.75% per annum, payable semi-annually in arrears on September 15 and March 15 of each year. Beginning March 15, 2022, the interest rate on the subordinated notes resets quarterly to a floating rate per annum equal to the then-current three-month LIBOR plus 3.616%, payable quarterly in arrears on June 15, September 15, December 15, and March 15 of each year to the maturity date or earlier redemption.

On any scheduled interest payment date beginning March 15, 2022, the Company may, at its option, redeem the subordinated notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest.

The subordinated notes are unsecured and rank equally with all other unsecured subordinated indebtedness of the Company, including any subordinated indebtedness issued in the future under the indenture governing the subordinated notes. The subordinated notes are subordinated in right of payment to all senior indebtedness of the Company. The subordinated notes are obligations of the Company only and are not guaranteed by any subsidiaries, including the Bank. Additionally, the subordinated notes are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s subsidiaries, meaning that creditors of the Company’s subsidiaries (including, in the case of the Bank, its depositors) generally will be paid from those subsidiaries’ assets before holders of the subordinated notes have any claim to those assets.

For regulatory capital adequacy purposes, the subordinated notes qualify as Tier 2 capital for the Company. If in the future the subordinated notes no longer qualify as Tier 2 capital, the subordinated notes may be redeemed by the Company at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest, subject to prior approval by the Board of Governors of the Federal Reserve System.
