Explanation of Responses:

1. I received a distribution of formerly restricted shares of stock and made an advance election to satisfy my tax payment obligations by selling shares to Questar.

2. As of February 16, 2009, I have 50,293.2470 equivalent shares of stock in Questar's Employee Investment Plan. The number of equivalent shares will fluctuate as Questar's stock price changes; this fluctuation does not reflect any transactions that should be reported.

3. Phantom stock units will be converted to cash per my elections on or within 5 years of my termination of employment (subject to 6-month delay if necessary to comply with IRC 409A), or upon my death or Disability.

4. I also receive phantom stock units as a result of my participation in an excess benefit plan. I have 9,402.2230 shares in it in addition to my shares in a deferred compensation plan. I also receive dividends.
