On September 24, 2015, Xenith Bankshares, Inc. (the “Company”) entered into an Amendment to Credit Agreement (the “Amendment”) with Raymond James Bank, N.A. (the “Lender”) that amends certain provisions of the Credit Agreement, dated as of September 30, 2014 (the “Credit Agreement”), between the Company and the Lender.

The Lender, or its affiliates, have provided, and may in the future from time to time provide, certain commercial and investment banking, financial advisory and other services in the ordinary course of business for the Company, for which the Lender, or its affiliates, has in the past and may in the future receive customary fees and commissions.

The foregoing description of the Amendment is qualified in its entirety by reference to the Amendment, a copy of which is attached as Exhibit 10.1 hereto and incorporated herein by reference. The Credit Agreement was previously filed as Exhibit 10.1 to the Company’s Current Report on Form 8-K on October 1, 2014.

The information set forth above under “Item 1.01. Entry into a Material Definitive Agreement” is hereby incorporated by reference into this Item 2.03.
