1	These equivalent shares are allocated to my account in Questar's Employee Investment Plan as of July 31, 2002.
2	These numbers include vested options only. Detailed information concerning my options has been previously disclosed.
3	I defer compensation each month that is accounted for with phantom stock units. I also participate in an excess benefit plan that is accounted for with phantom stock units. The total includes phantom stock units in both plans as of June 30, 2002. During June, I had 82.1991 phantom stock units allocated to my deferred compensation plan account at a price of $24.60 per share.
