Explanation of Responses:

1. As of September 13, 2004, I have 2,271.3359 equivalent shares of stock in Questar's Employee Investment Plan.

2. Phantom stock units will be converted to cash beginning at retirement; my retirement date is unknown.

3. I receive phantom stock units as a result of my participation in an excess benefit plan. This total includes 3,052.0568 units in such Plan in addition to units held through my account balance in a deferred compensation Plan.

4. The question about dates is irrelevant since I am not reporting any changes in my stock options.

5. 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. My total reported includes installments of my 2001, 2002, and 2003 options that vested since the date of the last report.
