Explanation of Responses:
1. As of July 30, 2010, I have 2,645.1331 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.
2. The option vests in three annual installments beginning on March 5, 2010.
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. The restricted stock units vest in three equal annual installments beginning on July 1, 2011, subject to accelerated vesting upon the occurrence of certain events a set forth in the award agreement.
5. This number varies from prior Form 4 due to rounding.
