NatSource Deal Valuation

Bob,

I have compiled three Excel files that value Pete Keavey's Gas Daily swaps
and options. In looking at the spreadsheet that you sent, I found these to
be the most incorrectly valued. In order to get the valuations, I had book
administators run calculations in the ERMS system. These values should
correlate with how credit valued these deals. Each file consists of a
summary worksheet and a detail worksheet for each deal. Please feel free to
call, or have Homer call, with any questions that you have.

Thank you,
