(1)	This total reflects a gift of Stock for 28,000 shares on December 20, 2011.
(2)	This date is unknown until I retire as a director.
(3)	On December 30, 2011, I elected to reallocate the portion of my account balance in a Questar Corporation ("Questar") deferred compensation plan (the Plan) which were deemed invested in phantom stock units of QEP Resources, Inc., ("QEP") into Questar phantom stock units pursuant to the terms of the Plan. The QEP phantom stock units became a part of the Plan following the spin-off of QEP on June 30, 2010.
(4)	I deferred my director's fees, and such fees are accounted for in phantom stock units that are credited with dividends.
