Subject: rate for tenaska deal daren , when we met regarding the rate for the tenaska gas management agreement , you guys mentioned that it would be tied to an index - - could you restate for me how that is to work - - it will start out 4 cents per mmbtu based on the greater of the volumes nominated through the supply contracts or the actual deliveries to the plant . then the fee will vary month to month ? year to year ? based on what index ? thanks , sandi
