After looking at this I realize it may not be as helpful as I thought - 
certainly would need to add more analysis on the delivery obligations like FM 
and other rights to interrupt.  Call if you have any questions (713 853 6349).

ps  if you get a chance I would love to see the form PGE used in addition to 
the WSPP - I think you said it was PGE 11.

Thanks
Have a great weekend.
