[1] For each of the respective debentures, the Company has the right at any time, and from time to time, to defer payments of interest on the Junior Subordinated Debentures for a period not exceeding 20 consecutive quarters up to the debentures’ respective maturity dates. During any such period, interest will continue to accrue and the Company may not declare or pay any cash dividends or distributions on, or purchase, the Company’s common stock nor make any principal, interest or premium payments on or repurchase any debt securities that rank equally with or junior to the Junior Subordinated Debentures. The Company has the right at any time to dissolve each of the trusts and cause the Junior Subordinated Debentures to be distributed to the holders of the Trust Preferred Securities.
