(1) I exercised an option to purchase 9,914 shares of stock using 3,932 shares as consideration. I satisfied my tax withholding obligation by selling 1,972 shares to Questar.
(2) As of November 4, 2004, I have 30,041.9500 equivalent shares of stock in my account 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 beginning at retirement; my retirement date is unknown.
(4) I receive phantom stock units as a result of my participation in an excess benefit plan. This total includes 3,160.3792 units in such plan in addition to units held through my account balance in a deferred compensation plan.
