TRADING OUTSIDE OF NORMAL BUSINESS HOURS AUTHORIZATION LETTER To: Deutsche Bank Alex. Brown I wish to have the ability to enter orders for execution in equity securities outside of normal trading hours (9:30 am — 4:00 pm EST) in my brokerage account with Deutsche Bank Alex. Brown. In order for Deutsche Bank Alex. Brown to execute such transaction on my behalf, I represent that I understand the following: I am aware of the material risks associated with trading equity securities outside of normal trading hours, including but not limited to: W Risk of Lower Liquidity. There may be lower liquidity during extended hours trading as compared to regular market hours. As a result, your order may only be partially executed, or not at all. Liquidity refers to the ability of market participants to buy and sell securities. 9 Risk of Higher Volatility. There may be greater volatility in the price of securities during extended hours trading than during regular market hours. As a result, your order may only be partially executed, or not at all, or you may receive an inferior price during extended hours trading than you would during regular markets hours. W Risk of Changing Prices. The prices of securities traded during extended hours trading may not reflect the prices either at the end of regular market hours or upon the opening of the next morning's trading session. As a result, you may receive an inferior price during extended hours trading than you would during regular market hours. V Risk of Unlinked Markets. Depending on the extended hours trading system or the time of day, the prices displayed on a particular extended hours trading system may not reflect the prices in other concurrently operating extended hours trading systems dealing in the same securities. Accordingly, you may receive an inferior price in one extended hours trading system than you would in another extended hours trading system. IV Risk of News Announcements. Issue
