Any transferee in a permitted transfer must agree in writing to be bound by the same restrictions, and any required public filings must clearly indicate the nature of such transfer. Stephens Inc. may, in its discretion and at any time and from time to time, with notice to the other Representatives, release all or any portion of the shares of our common stock and other securities that are restricted by these agreements from the restrictions listed above. Nasdaq Listing Our common stock is listed and traded on the Nasdaq under the symbol “SFNC.” Indemnity We have agreed to indemnify the underwriters and their affiliates, selling agents and controlling persons against certain liabilities, including certain liabilities under the Securities Act. If we are unable to provide this indemnification, we will contribute to the payments the underwriters and their affiliates, selling agents and controlling persons may be required to make in respect of those liabilities. Stabilization Transactions In connection with this offering, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock, including stabilizing transactions, short sales and purchases to cover positions created by short sales. Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our common stock while this offering is in progress.
