|5. |  | (a) |  | The above are the essential binding terms of the transaction in question. If a formal master physical agreement is in effect between the parties, then the above confirmation terms are subject to that agreement. In the
event of any conflict between this transaction and the terms of the formal agreement, the terms above prevail. If no formal agreement exists, then the parties will finalize and sign one, failing which this transaction remains binding on the parties.
Upon finalizing that agreement, the above transaction will form a part of, and be subject to, that formal agreement.
