Explanation of Responses:

1. I exercised an option to purchase 4,948 shares of stock using 1,774 shares as consideration. I satisfied my tax withholding obligation by selling 1,364 shares to Questar. This total also reflects a gift of 554 shares made on June 6, 2005 at a price of $64.10 as well as a gift of 30 shares made on June 13, 2005 at a price of $64.28

2. Phantom stock units will be converted to cash beginning one year after my retirement. I retired effective April 30, 2005.

3. During my employment, I also received phantom stock units as a result of my participation in an excess benefit plan. This total includes 3,592.1336 units in such plan in addition to units held through my account balance in a deferred compensation plan. I receive dividends on those units.
