Nicor Gas Company

Let's verify that this is an IOU. The Master should be sent to the attention
of Dave Brown and you should advise Cary of when it was sent to the

ps Remind me to give you both copies of Tana's utility analysis. Also,
Marie, let's talk about the utility language and circulate for comment.
