Citizens May Invoice

The West Gas Desk built up a negative imbalance on Citizen's TA
(Transportation Agreement) 97ZH. Citizens purchased 23,175 MMBtu to apply to
this imbalance. For the May invoice, we need to subtract this amount from
usage. Enter the volume into the area where we show transportation by others
to the citygate. This is logical as we otherwise would have to transport
this gas in ourselves.

After this trade, the TA imbalance on 97ZH will be 30,688 MMBtu. ENA is
responsible for this imbalance. It is my understanding that future
imbalances will go to the 97ZH OBA rather than the TA. Therefore, this
current TA imbalance will be there until it is eliminated.

Call me with any questions.
