Zhiyong -

I have looked over the consolidated gas system inception document. Here are a few questions/observations:

1. Value all physical deals. Not just current month. This will require logistics to enter all forward transport rather than just current month. (This is not an issue, just needs to be addressed as we go)

2. Term transport in new physical system would require spread option model to be in place.

3. Storey - Would all term transportation be a spread option and we would set the correlations to one if there was no optionality?

4. CPR is currently used as a back up if Sitara goes down. What would we do if the new system goes down?

5. What is the functionality to downstream systems going to look like? (Risktrac - V@R, credit)

6. Will calculations be performed from the same new system as Global Markets?

7. What will happen if: There is a fixed price physical deal where the risk components are split?

Example: Price : NG-PRICE Basis: FT-WEST Index: INTRA-WEST
