"3. PRICES AND OPEN POSITIONS

3.1 We will provide you with "bid" and "offer" prices in respect of currencies through our Trading Station or Dealing Desk. The prices that we quote are determined by us and usually represent a mark-up or markdown of inter-bank dealing rates. Each price shall be effective and may be used in a dealing instruction prior to the earlier of its expiration time and the time, if any, at which it is otherwise withdrawn by us. A price may not be used in a dealing instruction after such time. Each price shall be available for use in a dealing instruction for a transaction with a principal amount not to exceed a maximum determined by us. You acknowledge that these prices and maximum amounts may differ from prices and maximum amounts provided to other customers of ours and may be withdrawn or changed without notice. We may in our sole discretion and without prior notice to you immediately cease the provision of prices in some or all currency pairs and for some or all value dates at any time."
