Explanation of Responses:

1. As of August 13, 2004, I have 29,978.4897 equivalent shares of stock in my account in Questar's Employee Investment Plan.

2. As previously reported, the options granted in February of 2001, February of 2002 and February of 2003 vest in four equal annual installments beginning six months after grant. The total reported for Ms. Holbrook includes installments of her 2001, 2002, and 2003 options that vested since the date of the last report.

3. This date is unknown since I am only reflecting my total in phantom stock units at this time.

4. I receive phantom stock units as a result of my participation in an excess benefit plan. This total includes 2,996.4022 units in such plan in addition to units held through my account balance in a deferred compensation plan.

5. I exercised an option to purchase 1,545 shares of stock using 644 shares as consideration.
